As the company transforms from exploration to development, its objective is to delineate a development scenario and process route for SSM with respect to achieving the highest market value from a suite of in-demand products.

It also aims to tighten exploration costs to focus only on areas with compelling geological models supported by positive exploration results.

The company recently produced HPA assaying of more than 99.99% aluminium oxide from metallurgical precipitation test work at SSM.

It is investigating both vat leach of lump material and agitated tank leach of concentrates using sulphuric acid.

Other targeted high value speciality commodities such as magnesium oxide and vanadyl sulphate will be examined with a prefeasibility study underway.

In addition, the company is also exploring for gold, silver and copper at the Mt Remarkable Project 200 kilometres southwest of Kununurra, which comprises more than 3,000 square kilometres of exploration leases under application.

Chairman Anthony Barton has been involved in founding and growing several successful listed public companies with extensive knowledge in capital markets, corporate finance, funds management and venture capital.

Barton is the founding executive chairman of boutique investment bank Australia Heritage Group and has 34 years’ commercial experience having acted in senior executive and director capacities for two leading stockbroking firms.

What does King River own?

The company owns the Speewah project, which has evolved over the last decade to a world-class deposit with respect to strongly supported development.

SSM is the largest vanadium-in-magnetite deposit in Australia with the highest vanadium grade in magnetite concentrate.

The vanadium deposits comprise a measured, indicated and inferred mineral resource of 4.712 billion tonnes at 0.3% V205, 2% titanium and 14.7% iron.

King River owns 785 square kilometres of mineral leases covering a unique geological feature in the eastern Kimberley of WA called the Speewah Dome.

On completion of the PFS later in 2019 the company plans to use the technical and financial information to identify partners in jointly funding a definitive feasibility study (DFS).

The DFS will include scaled up pilot plant programs, alternative production scale scenarios and pre-development applications.

A 31-hole reverse circulation drilling program at the Junction prospect near to existing vanadium resources has begun with samples sent to the assay laboratory and to be reported on in due course.

Additionally, in 2015 King River identified the presence of high-grade gold, silver and copper at what is now the Mt Remarkable project in the east Kimberley region of WA.

These surface discoveries of up to 4 metres at 113.26 g/t gold including 1 metre at 346 g/t led geologists to establish a new geological model and apply contemporary tools and methodology for exploration work.

The next phase of drilling will test the Trudi Main, Trudi East Extension, Trudi Main Deeper, new veins and targets generated by 2019 reconnaissance activities.

Inflection points The company plans to spend a total of $1.1 million this quarter with $450,000 allocated to the scoping study and PFS work King River expects some of its application licenses to be granted this year opening exploration opportunities for new high-grade gold deposits On completion of the PFS later in 2019 the company plans to identify partners in jointly funding a definitive feasibility study (DFS) Identifying commercialisation strategy

The board is pleased with the progress of the SSM PFS and is formulating the best commercialisation strategy for development of the project.

After the both the PFS and DFS is completed, the study partners will jointly share ownership of all technical information surrounding the project and will have earned an option to acquire a majority direct equity in the project by providing future funding.

King River has also begun a 31 hole reverse circulation drill program for 1,600 metres at the Junction prospect, near existing vanadium resources, with samples being progressively sent to the assay laboratory. 

Definition of additional resources on a Mining Lease may help expedite a development in the future.

The company is engaging a tailings storage facility (TSF) expert to develop the most environmentally sustainable strategy for dealing with any waste from the proposed operation.

About 70% of the mined material is likely to be rejected at the beneficiation stage and may be replaced back into the mined pit.

King River is also working with independent professionals to report alumina and magnesia in its database and include these values in the PFS.

<![CDATA[News - King River Resources confirms high initial precipitation values for iron oxide and titanium dioxide products ]]> https://www.proactiveinvestors.com.au/companies/news/221691/king-river-resources-confirms-high-initial-precipitation-values-for-iron-oxide-and-titanium-dioxide-products-221691.html King River Resources Ltd (ASX:KRR) has received positive results from metallurgical precipitation test work from the Speewah Specialty Metals (SSM) Project in the East Kimberley of Western Australia.

The company is investigating both vat leach of lump material and agitated tank leach of concentrates using sulphuric acid.

Scoping level capex and opex costings have supported the agitated tank concentrate leach option as the preferred process route to produce vanadium pentoxide (V2O5), titanium dioxide (TiO2) and iron oxide (Fe2O3) products.

READ: King River Resources’ test works continue to optimise Speewah Specialty Metals Project

In addition, King River has targeted other high value specialty commodities such as high purity alumina (HPA), magnesium oxide and vanadyl sulphate.

A prefeasibility study (PFS) is underway and is examining several process routes to extract these commodities.

Metallurgical refining test work has initially focused on precipitating iron, aluminium and titanium products from the sulphuric acid leach solutions as these metals occur in the highest concentrations.

READ: King River Resources’ shares surge after producing >99.99% purity aluminium oxide

The Fe2O3 chemical precipitation tests have used a sulphuric acid leach solution from the 5.6mm lump agitated vat leach and column leach tests completed by Nagrom.

These leach solutions contained 32-35g/L iron. The iron reduction method was used to initially precipitate a hydrated ferrous sulphate from the leachate at 81- 82% precipitation efficiencies.

The hydrated ferrous sulphate was washed to help remove entrained contaminants including vanadium and titanium.

The final precipitate was dried and staged calcined up to 1000°C to produce an Fe2O3 product that assayed 67.13% iron, with 1.91% magnesium and 0.21% aluminium.

Further iron reduction, purification and other methods of producing Fe2O3 are under investigation to develop the best Fe2O3 process route and maximise acid recycle or regeneration for the SSM project.

High-purity titanium dioxide products

King River’s TiO2 chemical precipitation tests have used the sulphuric acid leach solution from the 5.6mm lump column leach tests after iron reduction and precipitation of ferrous sulphate.

These leach solutions contained 3.4-3.9g/L titanium. The hydrolysis method has been used successfully to precipitate titanium dioxide from the leachate at 87-92% precipitation efficiencies.

Further hydrolysis and other methods of producing TiO2 are under investigation to produce 98% and high purity 99.5% TiO2 products and develop the best process route for the SSM project.

Directors comments

The King River board continues to be most encouraged by this ongoing test work, and in particular these excellent initial precipitation efficiencies of iron oxide and titanium dioxide products from a pregnant sulphuric acid leach solution.

These ongoing tests of a range of different extraction methods will enable King River Resources to identify the optimal process route to produce high grade, high value vanadium pentoxide, titanium dioxide, iron oxide and alumina products to be incorporated into a PFS for later in 2019.

A prefeasibility study (PFS) is underway and is examining several process routes to extract these commodities.

Metallurgical refining test work has initially focused on precipitating iron, aluminium and titanium products from the sulphuric acid leach solutions as these metals occur in the highest concentrations.

In the first HPA precipitation test TSW Analytical trialled the hydrogen chloride (HCl) gas sparging method directly on the leach solution from the 5.6mm lump flooded column leach test.

READ: King River Resources achieves high vanadium-titanium extractions in Speewah metallurgical work

This test was designed to demonstrate HPA could be extracted from the sulphate leach solutions before the solution had any other metals removed or had been pre-concentrated.

In the first stage of the process, HCl gas was bubbled through the leach solution to precipitate aluminium chloride hexahydrate (ACH).

This first ACH precipitate was dissolved in water and purified by additional HCl sparging steps to recrystallise purer ACH at each step.

The final ACH precipitate was then calcined and purified to produce high purity alumina assaying >99.99% aluminium oxide (4N HPA) purity.

Directors comments

King River is encouraged by this initial HPA precipitation test result, which has the potential to add a material new revenue stream to the SSM project.

Steps are currently being made to try and include aluminium and magnesium in King River’s JORC resource statements to enable these potential future revenue streams to be included in prefeasibility studies.

Recent test work and studies have identified a clear path forward for the project based on sulphuric acid leaching to produce vanadium, titanium and iron products.

READ: King River Resources’ study reveals reduced capital costs for Speewah Specialty Metals Project

The sulphuric acid leaching method is also digesting a large percentage of other valuable, and globally critical metal elements (aluminium and magnesium), used in several technological and industrial processes, including the master and super alloys found in aerospace and transport products, LEDs, batteries, medical equipment, and other applications.

King River’s SSM Project cannot be easily compared with other emerging global vanadium projects which may rely solely on the future price and demand for only vanadium products.

SSM - metals targeted

Now that the leach test work has successfully demonstrated very good metal extractions from both lump and concentrates in sulphuric acid, King River’s focus will shift more to precipitation test work to recover the other targeted metals from the leached solutions.

The company will continue to focus on important metallurgical test work and studies as part of its PFS, including:

• Complete heated agitated leach and further flooded column leach test work to confirm the optimum process and conditions.
• Complete hydrometallurgical process flow sheet development trialling solvent extraction, ion exchange, thermal hydrolysis and chemical precipitation methods. Regeneration of sulphur values as sulphur dioxide (SO2) from the iron product is an important part of the process as it has the potential to reduce the sulphuric acid requirement.
• Options analysis into the capital and operating costs for an on-site sulphuric acid plant compared to importing acid and contract diesel power generation, including the supply, port access and transport of sulphur and sulphuric acid.
• Re-assay reverse circulation drill pulps in storage for aluminium and magnesium, plus other rock forming elements, for inclusion in a new resource statement. The drill samples were originally assayed prior to 2012 for vanadium, titanium and iron.
• Geotechnical studies on drill core to help finalise pit design.
• Environmental, heritage and marketing studies.

The SSM project plan is to produce vanadium, titanium and iron products, along with other potential high-value specialty commodities.

READ: King River Resources achieves high vanadium-titanium extractions in Speewah metallurgical work

King River has engaged Como Engineers in Perth to compile scoping study level (±30% accuracy) capital expenditure (CAPEX) and operating expenditure (OPEX) cost estimates for the beneficiation, leach and metal recovery processing facility and the acid contact and regeneration plants required for on-site sulphuric acid production.

The study investigated two sulphuric acid leaching processing options:
• Static flooded vat leaching of coarse lump material; and
• Agitated tank leaching of a coarse concentrate.

The study has provided an early indication that the agitated tank leaching option should be the focus for future metallurgical test work and investigations.

King River is encouraged by the initial CAPEX estimate, as it has fallen within the lower range of the company's initial target of US$650-750 million for a three-commodity project (vanadium, titanium and iron).

The company has ambitions to produce at least five high purity metal products, including high purity alumina (HPA).

The OPEX is also below King River’s initial target range but it will require additional costs added (including mining, power plant operation, borefield water, tailing disposal, campsite, and product transport and sales).

READ: King River Resources sets vanadium milestones for 2019

Importantly, the latest study provides a clear picture for focusing on the next phases of test work and studies.

A high priority will be to reduce the acid plant capital and operating costs, including a comparative economic study based on using imported sulphuric acid.

King River is committed to examining the lowest capital and operating cost project development strategy and report a PFS towards the third quarter of 2019.

The new results support advancing the new specialty metals project development plan for Speewah, which includes on-site processing of high purity products and the potential for scalability and cost savings.

READ: King River Resources sets vanadium milestones for 2019

King River chairman Anthony Barton said: “The board is most encouraged by the new vat and column leach test results, particularly the flooded column result as it most closely resembles a vat leach operation.

“Successful conclusion of the tests will allow us to finalise the vat leach plant design and costings as soon as possible.”

The heated flooded column leach test work used 20% sulphuric acid on 5.6 millimetre lump magnetite gabbro, reporting 90% vanadium and 47% titanium extractions after 14 days.

Comparative heated microleach testing also used 20% sulphuric acid on 106 micron magnetite-ilmenite concentrate and showed 97% vanadium and 62% titanium extractions after 3 days.

King River will progressively transition laboratory test work towards more diagnostic vat leach tests as well as work to extract the metals back out from sulphuric acid leach solutions.

Methods to be trialled include solvent extraction, ion exchange, thermal hydrolysis and chemical precipitation.

The company hopes to advance toward producing vanadium, titanium and iron products at the lowest possible unit costs.

King River non-executive chairman Anthony Barton spoke to Proactive Investors’ Stocktube video channel last week, highlighting King River was looking to update its Speewah Vanadium-Titanium-Iron Project scoping study by late March 2019.

READ: King River Resources advancing new vanadium-titanium-iron development plan for Speewah

The chairman also flagged a late-July 2019 completion of the Speewah project pre-feasibility study (PFS).

Barton said in the Proactive elevator pitch: “The Speewah project has genuine potential of producing a diversified range of metal and related products including vanadium, alumina, iron, magnesium, fluorspar and titanium.”

The project has the largest vanadium in titanomagnetite-hosted resource in Australia.

Investors in the company pulled out key takeaways from the presentation attracting attention online.

These included the success this month of sulphuric acid leach test work at the project and the months the company hopes to deliver the updated Speewah scoping study and new PFS.

Barton affirmed: “King River is hoping that the current run of encouraging test work will enable us to present our shareholders with a new scoping study by late March of 2019, and hopefully a pre-feasibility study around July of 2019.

“The project will be designed to be modular in function and therefore scaleable.”

 

King River’s chairman highlighted the very large size of the Kimberley region project near the town of Kununurra and the Cambridge Gulf Limited-managed Wyndham port.

Barton said: “The Speewah resource has been measured by leading independent resource consultancy CSA at 4.7 billion tonnes, assaying an average of 0.3% vanadium, 2% titanium, and 14.7% iron.

“That resource is currently 600% larger than the next biggest peer resource of its kind in the world.

“Earlier studies have identified, but not included in those JORC measurements, that this mineralisation also hosts around 12% alumina and 4% magnesium.”

READ: King River Copper reveals improved process route for vanadium recovery at Speewah

The preliminary pit shell is about 320 million tonnes, being 4.2 kilometres long and 1.1 kilometres wide, with an attractive low stripping ratio of 0.4.

Barton said: “That means there is one tonne of ore for each 1.4 tonnes mined.

“This mineralisation is disseminated and it is homogenous, and it’s quite consistent in grade. So it could be open-cut-mined using modern large-scale iron ore types of mining methods.”

King River’s chairman highlighted the Speewah ore body was different those held by the company’s vanadium peers.

Barton said: “Its size, the flat-lying shape at surface, the grade consistency and the disseminated, and mostly unoxidised, nature of the mineralisation does make it most amenable to modern-day large-scale mining methods.”

The current preliminary mining pit shell modelled is focused on only one of three deposits, or 8% of JORC resources, meaning a modular, scaleable approach could be taken to expansion and development.

Recovery work shift in thinking

King River has undertaken recovery work over the past 18 months in a bid to discover the best way to mine, process and produce a diversity of high-purity metal products.

While the 2018 calendar year focus was mostly on the capital intensive large-scale hydrochloric acid-leaching process, King River is now looking at a sulphuric acid vat-leach process.

Barton said: “The results to date are most encouraging.

“Over the last four months, our testing has been investigating the dissolving behaviour of various metals under different physical conditions, including different particle sizes.”

These have included 2, 3.35, 5.6 and up to 10-millimetre-sized particles.

The bottle roll sulphuric acid leaches on run-of-mine (ROM) magnetite gabbro lumps crushed to sizes of 10mm, 5.6mm and 3.35mm report 77%, 84% and 84% vanadium extractions (dissolved) respectively.

READ: King River Copper scoping study results outline viable vanadium project

The temperatures have ranged between ambient temperatures through to 70 degrees.

Acid strengths have been 10-20% when mixed in with water.

The company has also looked at concentrate batch sizes.

Those sizes have been assessed using real run-of-mine material.

King River expects to factor in its assessments to economic modelling that could produce a significantly-reduced capital expenditure and operational expenditure than the previous scoping study’s plant design.

Barton said: “Our object is obviously to identify the sweetest spot of a combination of all those variables to most efficiently and economically dissolve our targeted metals.

“We will discover that by varying some of those different variables we can enhance and also selectively subdue some of the rates of dissolving of those different metals into the acid solution.”

READ: King River Copper nears Speewah vanadium scoping study completion, metallurgical tests ongoing

The company hopes to narrow down its findings to put forward a specific option.

Barton said: “An excellent goal or objective for us in the next six months would be to try and identify the right variable setting that may efficiently dissolve the most valuable metals.

“Say, for example, 85% of the vanadium and 45% of the iron, titanium, alumina and magnesiums.

“By means of a vat-leaching run-of-mine material that might be sized at 5.6-millimetre or larger.”

King River realises the standard sizing of the rocks is a major change to the 106 microns modelled in its hydrochloric process scoping study and would have a material effect on costings.

Barton said: “Eliminating any need to fine-crush and grind, and/or to concentrate our ores would materially reduce the capital costs of building such a large-scale project.”

Over recent weeks work has started to assess the precipitation performances of the various metals coming out of the pregnant acid leach solutions.

Trials have included solvent extraction, ion exchange, thermal hydrolysis and chemical precipitation method trialling.

If King River takes the heap leach track, it expects to further save on unit costs by building and operating a sulphuric acid manufacturing plant on-site at Speewah.

This could have other benefits for cost control.

Once the heap-leach testing process finishes early this year, the company's board expects to authorise an in-depth PFS to determine key metrics for the project, including a net present value.

READ: King River Copper scoping study supports future fluorite mine

King River plans to make the appointment of a PFS project manager a top priority.

A preliminary project implementation timeline estimates full production could be achieved in July 2023.

Barton highlighted the location of Speewah project and the quality of the Tier 1 mining jurisdiction King River calls home.

He said: “The project location is also very close to a port, a mining workforce and the Asian export markets.

“Australia is considered a safe domicile to build world-class projects, and it’s a safe place to reliably long-term-source metal products.”

Copper-gold to a new subsidiary

King River also has the Mt Remarkable Gold Project in the East Kimberley.

Drilling has intersected a new, high-grade gold zone at the eastern edge of the Trudi Main Grid.

Results feature 4 metres grading 19.88 g/t gold including 1-metre at 69.30 g/t from 21 metres depth.

The new zone is open both up and down plunge to the east.

READ: King River Copper proposes a name change to King River Resources

Last year in November 2018 the company had a name change from King River Copper Ltd (ASX:KRC).

Speaking ahead of the proposed rebrand and name change, the company said in August 2018 it planned to place its Remarkable gold discovery into a new wholly-owned subsidiary called Kimberley Gold Pty Ltd.

The newco subsidiary would also house its parent company’s other Western Australian copper/gold tenements and applications for tenements outside the Speewah Dome boundary.

<![CDATA[News - King River Resources advancing new vanadium-titanium-iron development plan for Speewah ]]> https://www.proactiveinvestors.com.au/companies/news/212837/king-river-resources-advancing-new-vanadium-titanium-iron-development-plan-for-speewah-212837.html King River Resources Ltd’s (ASX:KRR) metallurgical results continue to support advancing a new vanadium-titanium-iron development plan for its Speewah Vanadium Project in the East Kimberley of Western Australia.

The company has been conducting sulphuric acid (H2SO4) bottle roll and diagnostic vat leach tests on magnetite-ilmenite concentrate and coarse magnetite gabbro lumps from the high-grade zone of the Central Vanadium deposit.

This test work was designed to assess whether the Speewah magnetite gabbro is best suited for vat or heap leaching prior to completing laboratory diagnostic vat and column leach tests.

Notably, bottle roll sulphuric acid leaches on run of mine (ROM) magnetite gabbro lumps that have been crushed to sizes of 10mm, 5.6mm and 3.35mm report 77%, 84% and 84% vanadium extractions (dissolved) respectively.

Observations and conclusions that can be drawn from the bottle roll test results include the following:

• Vanadium, titanium, iron, magnesium and aluminium leach efficiencies (extractions) are very good and support advancing the test work on lump material; and

• The vanadium and titanium extractions increase as the lump or grain size decreases for the same time interval.

Vat leach test work

King River’s diagnostic heated vat leach test work on 3.35mm and 5.6mm lump samples will allow the critical process parameters to be adjusted and recorded.

The initial diagnostic vat results show:

• Up to 92% vanadium and 61% titanium leach extraction after 10 days (240 hours); and
• Higher leach temperature and maintaining acid at 150-200mg/L have significantly increased the leaching rate of all metals.

Analysis

King River’s board is encouraged by the bottle roll and vat leach test results to date and will now fast-track the vat and column leach test work.

This will enable the vat leach plant design and costings to be finalised as soon as possible.

A trade-off analysis into the optimum particle size will also be undertaken.

There may prove to be some potential to use a coarse 2mm concentrate for the vat leach operation as it would significantly reduce the amount of material leached and possibly shorten leaching times.

A 2mm concentrate beneficiation plant would also be a simpler design to the facility used in the recently released vanadium scoping study that generated a 106 micron (~1/10th of a mm) concentrate.

Alternatively, if lump ROM material was chosen in the coming months to be the most economical option to be used in the PFS (pre-feasibility study), then there will be no fine grinding or magnetic separation circuit required.

During 2019, KRC aims to present shareholders with the most prudent commercial strategy to develop the Speewah vanadium deposits and advance towards the production of vanadium, titanium and iron products at the lowest possible unit cost.

Drilling has intersected a new, high-grade gold zone at the eastern edge of the Trudi Main Grid.

Results feature 4 metres at 19.88 g/t gold including 1-metre at 69.30 g/t gold from 21 metres depth.

The new zone is open, both, up and down plunge to the east.

The discovery confirms potential for other high-grade gold shoots

Drilling at Mt Remarkable has been completed for the year prior to the commencement of the wet season with 167 holes for 10,074 metres drilled.

Other highlights from the recently received assays including 2 metres at 10.47 g/t gold from 33 metres and 3 metres at 4.29 g/t gold from 27 metres.

The discovery of this new high-grade zone is very encouraging confirming the company’s belief that multiple high-grade shoots exist at Trudi and are yet to be discovered.

Assays still pending for deep diamond hole at Speewah

At the Speewah Vanadium Project, a deep diamond drill hole KCDH0010 was completed late November and the drill core has been sent to Perth with assays pending.

Speewah is in the East Kimberley region of Western Australia and the company is planning to publish a pre-feasibility study (PFS) this year.

The hole intersected a very broad alteration or fracture zone from 530 to 712 metres.

Metallurgical test work supports alternative development plan

As at December 19, 2018, ongoing metallurgical test work from Speewah continued to support an alternative development plan for the project.

The board has re-prioritised most studies around the focus for a much more flexible, modular engineered strategy.

This strategy better takes into consideration the advantage of owning such a large vanadium resource that is consistently disseminated, flat lying and outcrops at surface.

READ: King River Copper reveals improved process route for vanadium recovery at Speewah

The next phase of PFS work will examine more detailed costings of beneficiation and also review in more detail the capital and operating costs for a vat leach operation and sulphuric acid plant.

The successful conclusion of these tests and studies will lead to the planned publication of a PFS in 2019.

Speewah test work results expected soon

Results are expected in the near-term for magnetic separation testing and various acid leach testing.

This test work will lead into larger scale vat leach test work and a focus on extracting the vanadium, titanium and iron products from the leach solutions.

The results support an alternative development plan for the Speewah vanadium-titanium-iron project.

READ: King River Copper scoping study results outline viable vanadium project

King River’s recently reported scoping study demonstrated a viable business case with a healthy cash flow margin for a future development.

This was based on conventional on-site beneficiation of fine-grained concentrate and hydrochloric acid leach-solvent extraction refining at Wyndham producing vanadium pentoxide, titanium oxide and iron products.

While King River was encouraged by the results of the scoping study using these conventional processing methods, the company is committed to examining potentially lower capital and operating cost project development strategies that may also deliver a shorter development timeline.

The potential of using a coarse 2 millimetre concentrate for a heap or vat leach operation is now under revue as test results demonstrate it would reduce the amount of material leached by about 50% and potentially shorten leach times.

The photographs show lump magnetite gabbro before and after the 45-day bottle roll acid leach

Additionally, a 2 millimetre concentrate beneficiation plant would be a simpler design to the facility used in the recently released scoping study that generated a 0.106 millimetre concentrate with the potential flow-on of capital and operating cost savings.

While the new bottle roll and vat/column leach test work program is still at an early stage, the initial results on lump rock are most encouraging and now graduate this model of process route to the most preferred.

The scoping study’s objective was to determine the potential viability of an open pit mine with an on-site magnetic separation process followed by a hydro-metallurgical recovery of vanadium, titanium and iron.

The study presents a cohesive project that demonstrates a viable business case for further development.

Importantly, the scoping study sees a positive business case with a healthy cash flow margin that supports progression to the pre-feasibility study (PFS) stage.

The preliminary infrastructure strategy is to establish the primary processing facilities on site.

The processed product, a magnetic concentrate will then be transported to a hydro-metallurgical facility in Wyndham located 170 kilometres north.

Progressing to a PFS, full production 2023

The next stage of progression is completing a more in-depth PFS, which will provide a net present valuation (NPV) for the proposed operation.

The board will authorise the commencement of a PFS early in 2019 after current heap leach analysis has been completed.

King River intends to make the appointment of a project manager for the PFS a top priority.

A preliminary project implementation timeline estimates full production being achieved in July 2023.

The program is designed to test the main Chapman structure (a broad, shallow dipping, mineralised thrust zone with thicknesses up to 20 metres) in a complex litho-structural and geochemical setting.

READ: King River Copper nears Speewah vanadium scoping study completion, metallurgical tests ongoing

King River’s previous drilling at Chapman had defined a strong thrust zone over a strike of over 800 metres with arsenic-gold mineralisation in most holes.

The company believes that this consistent structure has potential to host a significant gold deposit.

The new deep diamond hole is designed to test the Chapman structure in a new geochemical and litho-structural environment close to a major north-east trending structure.

Cross Section of the designed drill hole shows interpreted extrapolation of the Chapman Thrust

A deep reverse circulation (RC) hole (220 metres) was drilled prior to positioning the diamond hole to assist with targeting.

The hole intersected the thrust zone with quartz veining and arsenic mineralisation (assays pending) allowing better extrapolation of the thrust at depth.

The new diamond drill hole is designed to a depth of 600 metres and will take about 2 weeks to complete (budgeted drill costs of $130,000).

King River said the evaluation of the best processing path to develop and market the Speewah deposits relies on the detailed process route and studies currently being undertaken.

While bottle-roll sulphuric acid-leaching test work is at a very early stage, KRC plans to examine the opportunity to heap or vat-leach lump material, or a coarse-grained concentrate, to extract vanadium pentoxide, iron oxide and titanium dioxide.

Other potential by-products include processing the dumps to extract the residual ilmenite to produce titanium dioxide, and possibly extract the aluminium and magnesium from the leach solutions to make high-purity alumina (HPA) and magnesium products.

The company’s board is focused on maximising the key strategic variables of the Speewah deposits, which it names as:

Their massive size;

The outcropping, flat-lying geometry;

The overall consistency of grades amenable to large-scale mining methods; and

The unique tenor of the magnetite, enabling the generation of a higher vanadium pentoxide concentrate grade compared to most peers.

Other metallurgical research includes investigating the production of titanium dioxide products (pigment grade and high purity plus-99% titanium dioxide), iron oxide hematite and vanadium electrolyte which is used in vanadium flow batteries.

A bottle-roll sulphuric acid leach test was completed by Nagrom Metallurgical, designed to provide baseline data on what metals leach under the best conditions such as acid concentration, fine grain size, agitation, high metal mineral content and relatively-low acid-robbing minerals.

The leach test also assessed the suitability of this sulphuric acid leach for column or vat leach tests on lump material and concentrate types, with or without agglomeration.

  READ: King River Copper confirms more high-grade gold hits from Mt Remarkable Project

Nagrom is undertaking further bottle roll tests on diamond core samples of magnetite gabbro with three different lump sizes.

After 12 days the vanadium and titanium are leaching slowly, with high leach rates for iron, aluminium and magnesium.

These leaches will continue into October when a decision will be made to continue the leaches and/or start a leach of a coarse-grained concentrate.

Additional magnetite-ilmenite concentrates are also being produced by Nagrom, using magnetic and gravity separation methods from metallurgical core, for use in hydrometallurgical tests.

These concentrates are from both the high-grade and low-grade zones of the magnetite gabbro as well as of different grind sizes suitable for different processing routes.

Laboratory test work utilising hydrochloric and sulphuric acid leach is being undertaken by TSW Analytical and King River has appointed ALS Metallurgy to complete salt roast-water leach-AMV testing to produce vanadium pentoxide.

King River reported: “This discovery of a new high-grade zone to the east of previous drilling confirms KRC’s belief that multiple high-grade zones exist on the Trudi vein and are yet to be discovered.

“This new high-grade zone is situated on the overall easterly plunge predicted from the intersection of the Grahame and Trudi veins.

“The mineralisation is from within a very intense zone of quartz adularia veining.”

READ: King River Copper receives new assay batch, 6 metres at 60 g/t gold

King River also reported RC drilling beneath the Trudi grid had continued to deliver high-grade results such as 2 metres grading 5.64 g/t gold, including 1 metre at 11.1 g/t.

Step-out exploration drilling undertaken 50 metres east of Trudi grid returned 5 metres grading 1.78 g/t gold, including 1 metre at 5.76 g/t.

King River said the step-out result opened up new high-grade shoot exploration opportunities to the east.

The company reported its best results from west of Trudi Main Grid were: 2 metres grading 5.64 g/t gold, including 1 metre at 11.1 g/t; and 15m grading 1.04 g/t gold, including 2 metres at 5.44 g/t.

Drilling west of Trudi Main Grid

Of its west drilling, King River said: “An unexpected change in dip of the main vein has caused some of the subsequent deeper holes to hit the vein much shallower than planned.

“These deeper holes have also intersected a second adularia vein, 6 metres south of the main vein, which is most likely a bifurcation of the main structure and possibly also host to mineralisation.”

King River plans to drill test the extend of its new zone near Trudi, taking drilling to the east and down-plunge.

Prospective veins near Trudi Main Grid.

Gold-hosting veins deliver

King River has claimed success from two main areas that it is targeting in the relatively new mineralised Southern and Northeastern veins at the project.

The east-west quartz adularia Jeniffer Vein has a strike length of more than 700 metres is part of the Southern veins and King River has received assays for nine RC holes there, with three holes returning significant mineralisation with grades up to 3.16 g/t gold.

The company is planning further drilling in the Southern veins, to find high-grade mineralisation.

Assays for five holes at Northeastern veins have been returned, with a best result of 2 metres grading 0.24 g/t gold.

King River said: “Reconnaissance exploration in vicinity of this drilling has identified more veins associated with soil gold anomalies.”

The company has additional reconnaissance work, rock-chip sampling and drilling planned for the prospective Northeastern veins.

Dry season campaign

The company’s drilling efforts will continue in October and November and are timed to get in before the Kimberley’s wet season starts.

The study outlines an open-pit development path for the fluorite project and the positive business case supports progression to the pre-feasibility study (PFS) stage.

The project’s Windsor fluorite deposit has a combined Indicated and Inferred resource of 6.7 million tonnes at 24.6% calcium fluoride located on granted mining leases.

Future operation would be resilient to product price

This scoping study was undertaken to determine the potential viability of an open pit mine with a crushing, separating, milling, and flotation circuit to produce acid grade fluorspar concentrates.

At a product price of A$625 per tonnes acid grade fluorspar, the project comprises an open-pit mining operation with a stripping ratio of 4.0.

The study demonstrates a project cash flow that supports continued investment in developing the project.

Notably, a 20% price drop in the fluorspar price still produced a positive cash flow project with an acceptable return on investment.

Board approves PFS

The board have been encouraged by the results of this scoping study to authorise the commencement of a PFS.

It will be completed at a standard to allow reporting an Ore Reserve and an economic analysis.

Key additional studies and test work include metallurgical test work, geotechnical drilling and pit optimisation studies, detailed operating and capital costs, environmental studies and off-take MoUs.

Since 2016, drilling has extended the main Trudi vein system to a potential strike length of nearly 1 kilometre.

Gold mineralisation has also been intersected at other locations including at the Grahame vein, and an area west at the Catherine vein.

Recent drilling widens Trudi target

The most recent exploration drilling undertaken along strike of the main high-grade Trudi discovery has identified zones where the host structures have thickened to widths in excess of 30 metres.

Mechanical issues over the past four weeks have delayed targeting of some deeper zones east along the Trudi Vein where the Grahame Vein is modelled to be in close proximity.

The intersection of this flat east trending Graham trend with a steep west plunging veining association has now been interpreted as the most likely control over the bonanza 100 g/t+ type grades reported in June.

READ: King River Copper strikes bonanza grade gold at Mt Remarkable

The suspended drilling program is expected to commence as a priority in the coming week.

King River’s recent identification of new epithermal gold mineralisation about 4 kilometres southwest of Trudi Vein may also prove significant for identifying potentially new higher grades and shoots along strike and/or down dip.

The production of high-purity vanadium pentoxide assaying 99.51% is another important milestone in King River’s plan to become a manufacturer of vanadium and titanium products.

Future test work will aim to improve upon this positive first result.

Notably, the process route being used is a known technology and potential has been identified for improvements to the vanadium pentoxide purity in future test work.

Final steps for completion of concept study

To finalise the concept study, the next processing and optimisation steps include:

• Produce high-value standard grade vanadium pentoxide flake suitable for the steel industry;
• Refine the high-purity vanadium pentoxide powder process suitable for chemical and battery grade products;
• Titanium dioxide test work to improve recovery of high-purity titanium dioxide and other titanium dioxde products; and
• Iron oxide hematite precipitation test work and maximise acid recovery.

In addition, the high-purity vanadium pentoxide product will be used in initial trials to make vanadium electrolytes (used in vanadium flow batteries).

READ: King River Copper strikes bonanza grade gold at Mt Remarkable

While bonanza grade gold hits at Mt Remarkable is a significant catalyst, equally important is King River’s progress on the concept study at the Speewah Vanadium Project in Western Australia.

King River's projects in the Kimberley region of Western Australia

Highlighting the potential scale, Speewah is Australia’s largest vanadium-in-magnetite resource, and comprises a resource of 4.712 billion tonnes at 0.3% vanadium, 2% titanium and 14.7% iron.

READ: King River Copper's Tony Barton discusses vanadium and gold at Proactive's CEO Sessions

King River’s strategy of close space drilling on the Trudi Vein at Mt Remarkable is proving highly effective in the identification and delineation of high-grade gold shoots.

Recent assays from diamond drilling returned an outstanding result of 2 metres at 16.78 g/t gold including 1 metre at 31.80 g/t gold from 15 metres.

Visible gold observed at Mt Remarkable

Significantly, identifying high-grade epithermal gold mineralisation at such shallow depths early in the exploration program has greatly enhanced the prospectivity of the numerous other under-explored vein systems mapped at Mt Remarkable.

The company believes there is genuine potential for repeats of similar high-grade gold shoots to be placed along the known 1 kilometre mineralised strike at Trudi.

Interestingly, the flat-lying nature of the Speewah mineralisation gives King River the opportunity to mine very large volumes of material with minimum waste.

As an example, 0.4 tonnes of waste to 1 tonne of mineralised material.

King River is also investigating the means for production of vanadium electrolyte products used in vanadium flow batteries.

Vanadium has outperformed cobalt, lithium and nickel

The price of vanadium pentoxide increased by about 160% between May 2017 and May 2018, thanks to tightening supply and strong orders from the steel industry which accounts for 90% of demand.

Vanadium prices outperformed cobalt, lithium and nickel during this period.

Despite limited mined resources, vanadium demand is on the rise as further uses for the metal are uncovered.

Vanadium is used in small amounts to significantly increase the strength of steel or titanium, making it useful in jet engines, high-speed aircraft, gears, axles, crankshafts, and superconducting magnets and ceramics.

Highlighting the potential scale, Speewah is Australia’s largest vanadium-in-magnetite resource, and comprises a measured, indicated and inferred resource of 4.712 billion tonnes at 0.3% vanadium, 2% titanium and 14.7% iron.

The flat lying nature of the Speewah mineralisation gives King River the opportunity to mine very large volumes of material with minimum waste.

As an example, 0.4 tonne waste to 1.0 tonne mineralised material.

The extraction methods that are being trialled to produce high purity products present further opportunities for the company to more readily value add to the much higher value vanadium electrolyte and titanium sponge products.

King River noted: "The nature of these different technical studies is complex and process optimisation does take time.

"Through this comprehensive scoping process, the company aims to present our shareholders with the most prudent commercial strategy to advance towards the production of high purity vanadium, titanium and iron products at the lowest unit cost."

Objectives of the Concept Study

The main objective of the Concept Study is to identify and address the technical hurdles necessary to complete a Scoping Study into the production of high purity vanadium pentoxide (99.5-99.9% V2O5), titanium dioxide (>99% TiO2) and iron oxide (>68% Fe2O3) products.

Production would utilise a novel hydrometallurgical process using a concentrate derived from the Speewah Central vanadium deposit.

King River is also investigating the means for production of vanadium electrolyte products used in vanadium flow batteries.

Items still to be addressed in the Concept Study include:

- Finalising the Hydrometallurgical Process Flow Sheet and capital and processing cost estimates;
- Finalising the Beneficiation Plant design and capital and processing cost estimates; and
- Final open pit optimisation and mining schedule study using the operating cost estimates.

Once these items have been addressed, King River will finalise a Scoping Study into the preliminary economics of the Speewah Vanadium Project.

Today’s intersections are deeper, while being located to the east of the early June high-grade gold hits.

This provides the potential of a more extensive system, not just a single high-grade shoot.

Today's highlights include: 3 metres at 41.75g/t gold from 16 metres; 3 metres at 38.70g/t gold from 22 metres; 2 metres at 66.50g/t gold from 27 metres; 4 metres at 39.78g/t gold from 31 metres; and 3 metres at 16.26g/t gold from 13 metres.

The new results now define a very high-grade gold zone that is currently open to the east and at depth.

These follow the results from three weeks ago which delivered: 4 metres at 113.29 g/t gold from 23 metres; and 3 metres at 34.8 g/t gold from 18 metres.

King River will continue exploration at speed with follow up holes to test for extensions.

Drilling has already commenced.

Drilling program outcome to date

The current reverse circulation drill program is a close spaced grid with a 5 metre spacing designed to test and delineate the trend of high-grade gold mineralisation.

The additional goal is to identify other nearby high-grade shoots.

The grid has now been extended to the east to follow up on and extend this new high-grade zone and a second deeper grid at a 10 metre spacing has also commenced.

A four diamond drill hole program is scheduled to start later this week to provide structural information on the high-grade gold zones.

Importance of the latest results

By identifying near-surface and high-grade epithermal gold mineralisation so early in the exploration area, this enhances the prospectivity of the numerous other under-explored vein systems already mapped.

King River noted that the strategy of initial close space drilling on the Trudi Vein has proven highly effective in identifying, delineating and extending high grade gold zones.

The company added that it validated the view that there should be potential for repeats of additional high-grade gold shoots placed along the known ~1 kilometre of mineralised strike at Trudi.

Result interpretation

Interpretation of results so far have shown gold mineralization at Trudi to be broadly associated with the main adularia vein, however the high-grade mineralisation is not constrained to the intense adularia zones as previously thought, but forms plunging shoots that trend within the broader quartz adularia structure.

It is interpreted that the overall trend of mineralization follows the intersection of the Grahame vein, another mineralised quartz adularia vein, with the Trudi Vein.

This trend is untested by historical drilling beyond the main zone.

King River last traded up 4.8% at 8.8 cents.

The interest is driven by the next exploration steps at the Trudi target, located within the wholly-owned Mt Remarkable Project in the East Kimberley of Western Australia.

READ: King River Copper strikes bonanza grade gold at Mt Remarkable

A more powerful reverse circulation rig has been mobilised to site to enable the drilling of the deep exploration holes east of the main Trudi target where no previous historic drilling has been completed.

Three deeper holes for 588 metres have been completed.

Drilling goal

Exploration in this undrilled area has been designed to target where the shallow dipping, gold mineralised Grahame Vein is interpreted to intersect with the Trudi Vein.

The intersection of these two gold mineralised structures is interpreted to be a major controlling factor for the high-grade gold mineralisation currently being drilled at Trudi as part of the grid drilling program.

Next steps

Further exploration of the eastern extents of Trudi vein will continue once assays have been returned for the three completed deeper holes.

King River said that the next round of Trudi East exploration holes will aim to confirm the orientation of the Trudi vein and continue to test along the Grahame-Trudi intersection.

Three 200 metre spaced holes are planned to target the Grahame vein to assist in better targeting its intersection with the Trudi vein and to test for gold mineralization on the Grahame vein.

The diamond drill rig is expected to arrive in the coming week.

Fine visible gold has been observed in the latest holes at the eastern end of the current reverse circulation drilling grid of the Trudi Vein.

Drilling highlights from visible gold intercepts include:

• 4 metres at 113.29 g/t gold, including 1 metre at 346 g/t gold; and
• 3 metres at 34.8 g/t gold, including 1 metre at 50.5 g/t gold.

The first batch of results confirm multiple plunging high-grade shoots forming a core to the main Trudi mineralised zone.

Best results include 3 metres at 22.31 g/t gold, 3 metres at 9.84 g/t gold and 6 metres at 4.01 g/t gold.

As a reminder, last year the Trudi vein revealed 11 metres at 27.9 g/t gold.

More results to flow

A total of 46 holes for 1,600 metres have been completed so far, with today's assays from the first 650 metres of drilling.

Assays are pending for the rest of the holes drilled to date.

The current program is a close spaced reverse circulation grid with drill intersections aimed at a five metre spacing.

This is designed to test and delineate the trend of high-grade gold mineralisation and identify other nearby high-grade shoots.

Drilling will also provide insight into mineralisation controls and assist with future targeting of high grade mineralisation.

More diamond holes to be drilled

Four diamond drill holes are planned to be drilled mid-June to provide structural information on the current high-grade zones.

King River said that it is interpreted that the plunge component is structurally influenced by the intersection of the Trudi Vein with the Grahame Vein which is plunging to the east.

Exploration drilling of the undrilled eastern extents of the vein is planned later in the program.

The company is targeting additional new high-grade gold shoots.

READ: King River Copper surges on positive test results for high purity vanadium

New test work has upgraded vanadium concentrate by assaying 2.11% vanadium pentoxide, 16.23% titanium dioxide and 66.27% magnetite.

The Speewah and Mt Remarkable projects are in the East Kimberley region.

The beneficiation result shows that Speewah high-grade zone magnetite gabbro can be significantly upgraded by initially coarse grinding and magnetic separation methods.

This produces a magnetite-ilmenite concentrate at good grade and recoveries and rejects about 67% of the waste minerals in the sample.

The intermediate concentrate can be further upgraded by grinding to 120 microns and with further magnetic separation produce a magnetite-ilmenite concentrate of 2.11% vanadium.

Mass yield improves 27%

Mass yield has improved 27% to 16.58% from the mass yield used in the scoping study of 2012.

The beneficiation circuit has also increased vanadium and titanium recoveries, particularly the latter.

All previous beneficiation test work had been done at finer grind sizes where all the rock was ground to 45 microns before magnetic separation.

Coarser grain sizes

The new staged beneficiation circuit at coarser grain sizes has potential to reduce the cost of producing a magnetite-ilmenite concentrate at Speewah.

The final concentrate grind size of P80 120 microns compares favourably with other Australian vanadium projects where grain sizes of P80 75 and 106 microns are reported.

Further test work is planned to further improve the beneficiation process.

READ: King River Copper drilling lays platform for 2018 news flow from Mt Remarkable

The decision to substantially increase the exploration footprint around Mt Remarkable was triggered by the company’s recent high-grade gold discovery at the Trudi Vein and further knowledge gained in recent months by detailed analysis of historic work around the area.

Significant opportunity for additional high-grade discoveries

High-grade gold mineralisation at the Mt Remarkable Project is hosted by the Whitewater Volcanics, a Proterozoic stratigraphic horizon that is older than the Speewah group.

This horizon extends from Great Western Exploration’s (ASX:GTE) Hunter Project, where historical high-grade gold values of up to 50.65 g/t gold have been returned, through to King River’s Mt Remarkable project (highest grade of 90.7 g/t gold from drilling last year).

Past exploration between these two high grade projects has been sparse leaving excellent opportunity for additional high-grade discoveries within the Whitewater Volcanics.

Drilling planned to extend high-grade mineralisation

Once the applications are granted, King River is planning to identify and test new gold targets while advancing its existing prospects at Mt Remarkable.

The company’s ongoing analysis of last year’s geophysics, drill results and samples continue to give insights into mineralisation controls at the project.
