Resouro boosted by industry-leading REE results from Tiros samples
In the latest milestone for the massive Tiros project in Brazil, metallurgical test work on the ore has indicated that Resouro Strategic Metals and partner Altilium have the potential to achieve the highest rare earth extractions known across the industry.
- Resouro completes first steps of its metallurgy strategy with Altilium Group.
- Results from assessment of ~50kg sample from Tiros Central Block achieve industry-leading extraction results.
- Resouro to continue next steps with Altilium Group as it works towards PEA.
The met test results come just a month after Resouro (ASX:RAU) announced the 1.7 billion tonne maiden JORC resource for the Tiros project in Minas Gerais, Brazil, making it the largest JORC combined REE and titanium deposit of its type known in the world.
Resouro has now completed the first steps of its metallurgical strategy with partner Altilium Group after announcing key partners to advance the Tiros project.
An innovative global leader in metallurgy, Altilium Group has been conducting non-conventional rare earth test work. Its aim is to maximise extraction of the high-value metals with minimal waste, which is key to the economics of the project.
Altilium Group assessed an approximately 50kg representative sample, covering five diamond drill holes from the Tiros Central Block JORC compliant resource.
Three leach tests were conducted to understand the metal extractions, with the goal of generating a solution rich in rare earth elements and a residue enriched with titanium.
Notably, the third test, which incorporated a pre-treatment process, achieved the highest rare earth extractions known in the industry to date, including 96.2% extraction of the high-value magnetic rare earth elements.
This rigorous testing process, carried out at Core Resources Laboratories in Brisbane, involved air-drying and milling the sample.
