Yellow Rock Resources steps up pace at Gabanintha Vanadium Project

An update to the mineral resource estimate is underway following the best ever vanadium drilling grades recorded at the Project and should lead to a further boost in the resource base at Gabanintha. A mining study is also underway toward a development decision.
Yellow Rock Resources steps up pace at Gabanintha Vanadium Project

Yellow Rock Resources (ASX:YRR) is stepping up the pace at its Gabanintha Vanadium Project in Western Australia after recording the highest vanadium grades ever recorded at the project from drilling.

As a result, an update to the mineral resource estimate is underway and should lead to a boost in the vanadium resource at Gabanintha.

During the last quarter's drilling, Yellow Rock intersected grades measuring as high as 2.20% V205 while RC results had no less than 15 individual assays grading over 1.50% V205 in seven different drill holes.

While deeper diamond drill results found the presence of widths of a high-grade vanadium magnetite layer seen throughout the RC drilling, including a bumper 14 metres intercept at 1.44% V205 from 131 metres.

The consistency and predictable geology of the high grade vanadium magnetite zone and consistent thickness was impressive.

With grades well above 1% V2O5, with high iron and titanium content, should finally see Gabanintha ranked as a deposit that is comparable to global development and production projects.

Mining Study

Following the resource upgrade, AMC Mining Consultants will undertake a Mining Study and has recent vanadium expertise.

Beneficiation test work

With samples already selected from selected drill holes, Bureau Veritas Metallurgical Laboratories will conduct a beneficiation test work program under the supervision of the company’s consulting metallurgists.

Testing will include crushing and grinding tests, analysis of recoveries from oxide, transition and fresh mineralised materials using gravity and magnetic separation techniques and confirmation of suitable process plant options.

The metallurgical test program will provide key processing and recovery information which is will be used for development of an updated concept study and preliminary economic assessments.

Environmental impact assessment

Details are being finalised for the commencement of baseline environmental surveys as part of the EIA (Environmental Impact Assessment), and mining project approval processes.

These will initially involve field baseline flora and fauna surveys to be conducted in the spring season (September or October) by Biologic Environmental Pty Ltd.

Power supply

Yellow Rock has commenced a detailed analysis of the power supply required for the project.

Early planning of a MW scale solar-diesel-vanadium battery hybrid power plant for part or all of the project’s requirements is underway. The key objective is to ensure long-term and stable low power costs for the project lifetime.

Further work

The Centre for Exploration Targeting at UWA has been selected to conduct petrographic and mineralogical descriptions of the mineralised rocks at Gabanintha.

An experienced igneous petrologist with vanadium experience in similar deposits will lead the process. The results will provide essential information for understanding the nature and distribution of vanadium, iron and titanium at Gabanintha.


In all, an impressive growth period for Yellow Rock looks set to continue as it has also completed requirements for the application for a Mining Lease to cover the Gabanintha Vanadium Deposit. 

The Mining Lease application is a milestone as Yellow Rock begins the advance towards a detailed feasibility study over the coming year.

There was also a detailed review and engagement with key players in the traditional vanadium steel markets and the rapidly emerging Vanadium Redox Battery (VRB) Market.
