A GSN analysis of reconnaissance aircore drilling was undertaken by previous tenement holders and identified thick mineralised horizons of scandium and cobalt over areas within a well-developed laterite.



First time “the tenure has been explored for cobalt and scandium”

Great Southern Mining executive chairman John Terpu said: “This is the first time that the tenure has truly been explored for cobalt and scandium.

“At a reconnaissance stage of exploration, the extent of the mineralisation is encouraging and has potential for a small but exceptionally high-grade deposit of what are scarce and valuable commodities.

“The fact that the tenure is within 15 kilometres of significant processing mills and infrastructure adds to the development potential of the project.

“Further drilling programs are being planned at targets on this newly acquired tenure later in 2019.”

Four-metre composite assay samples from drilling returned up to 252 g/t scandium and 0.35% cobalt.

Outstanding results include:

12 metres at 116 g/t scandium and 4 metres at 0.02% cobalt; 

12 metres at 132 g/t and 4 metres at 0.03%;

16 metres at 130 g/t and 8 metres at 0.4%; and

4 metres at 102 g/t and 0.16%

The company is in the process of re-assaying the samples for multiple elements including platinum and palladium.

<![CDATA[News - Great Southern Mining identifies large-scale copper-gold porphyry system at Edinburgh Project ]]> Great Southern Mining Ltd (ASX:GSN) has identified a large-scale porphyry system at its Edinburgh Project near Townsville, Queensland.

Geological mapping and sampling identified the large copper-gold system known as Leichardt Creek over 6 kilometres, which has undergone very limited exploration.

Promising large-scale system

Great Southern Mining executive chairman John Terpu said: “The company has always held a firm belief in the high prospectivity of the tenure at our Edinburgh Park project and to get early exploration success on multiple targets creates a range of exciting opportunities to deliver value for shareholders.

“This is the first time that a company has systemically explored the outcropping mineralisation at Leichardt Creek and while the prospect is still at an early stage of exploration, it has the hallmarks of a promising large-scale gold-copper-molybdenum-rich porphyry system.”

Tier 1 deposits

The Leichardt Creek prospect is emerging as a large-scale late-carboniferous to early Permian-age mineralised porphyry system.

The carboniferous to early Permian is a major mineralising epoch in north Queensland associated with extensive felsic volcanism and intrusions responsible for the development of numerous tier 1 related deposits.

0.56% copper

Extensive mineralised gossanous quartz vein stockworks and disseminations appear to host polymetallic gold, silver, copper, zinc and lead mineralisation.

Previous rock chip sampling returned results of up to 0.56% copper, 0.12 g/t gold, and 0.45% molybdenum.

“Company changing discovery”

Terpu added: “The company will continue to develop the exploration concept and these deposits require systematic exploration in order to properly map the extent of the systems and identify the prospective parts of that system for targeted drilling.

“Our aim over 2019 is to identify multiple targets and make that company changing discovery.”

Regional mapping and geochemical programs are ongoing with geophysical surveys planned for quarter one 2019.

<![CDATA[News - Great Southern Mining receives excellent metallurgical test work results at the Mon Ami Gold Project in WA ]]> Great Southern Mining Limited (ASX:GSN) has received excellent metallurgical test work results at its Mon Ami Gold Project in Laverton, WA.

The preliminary gold recovery test work demonstrated excellent gold recoveries of up to 97% using conventional cyanide leaching and gravity concentration.


The test work begun utilising reverse circulation chips sourced from the company’s maiden drilling campaign in June and July, 2018.

Lower reagent requirements and course grind is expected to result in low processing costs.

Results add to “promising discovery”

Great Southern Mining executive chairman John Terpu said: “The metallurgical test work further demonstrates the potential for this project.

“We are extremely pleased with the results and they add to what is already a promising discovery.

“Where GSN differs from other junior exploration companies is the project’s potential operational logic and geographical compatibility – we already have a granted mining lease and the project is close to a number of existing mills and supporting infrastructure.

“We are busy planning the next drilling program designed to rapidly expand the resource and will continue the metallurgical studies for toll treatment options or potential near-term, low capital intensive development options.”

READ: Great Southern Mining posts maiden resource for Mon Ami Gold Project in WA

In November last year the company announced the maiden mineral resource estimate at the project of 1.1 million tonnes at 1.7 g/t gold for 59,000 ounces of contained gold.

Following the release of the maiden resource estimate, Great Southern commissioned the metallurgical test work to de-risk the exploration program.

This involved providing early sighter indicators of key parameters around conventional processes regarding gold discovery, grind size and reagent consumptions.

Further test work

Further test work is planned to optimise recoveries on fresh ore.

<![CDATA[News - Great Southern Mining posts maiden resource for Mon Ami Gold Project in WA ]]> Great Southern Mining Ltd (ASX:GSN) has posted the maiden JORC mineral resource estimate for its Mon Ami Gold Project, 25 kilometres southeast of Laverton in Western Australia.

Mon Ami’s resource estimate is an inferred 1.1 million tonnes at 1.7 g/t gold containing 59,000 ounces, using a 1 g/t cut-off.

The resource estimate was undertaken by mining consultancy firm SRK Consulting Pty Ltd and careful management of costs has allowed Great Southern to achieve a discovery cost per resource ounce of less than $15.

‘Surpassed early expectations’

Great Southern executive chairman John Terpu said the maiden resource estimate represented a major milestone and surpassed early expectations.

Terpu said the company anticipated the resource to grow as further drilling is undertaken.

He added: “The resource remains open in all directions and to achieve this result based on the limited drilling to date is exceptional.

“We are fortunate to have a granted mining licence and to have extensive infrastructure nearby which offers flexibility and development options for the company.”

Terpu thanked Great Southern’s contractors and consultants in their work, singling out Great Southern head of exploration Bryce Healy for his efforts in delineating Mon Ami’s maiden resource.

Mining and metallurgical studies underway

Some of the mineralisation captured within the current model at Mon Ami remains unclassified and has been excluded from the resource estimate due to cut-off, drill spacing and depth.

Specifically, the resource estimate excludes a number of holes from Great Southern’s maiden drilling program which noted mineralisation below 150 metres.

Metallurgical test work and mining studies are underway and, having received the necessary approvals, the company plans to undertake an extensive infill and extensional drilling program to better understand the deposit and its potential.
