Resouro announces 1.7Bt JORC rare earths Resource
Resouro Strategic Metals has announced the largest and highest grade rare earth elements and titanium dioxide resource in Brazil and one of the largest resources of its kind in the world.
- Resouro Strategic Metals announces 1.7 billion tonne maiden JORC resource
- The mineral resource estimate makes Resouro’s Tiros project the largest rare earths and titanium dioxide project in Brazil and one of the largest of its kind in the world
- The near-surface deposit includes high-value magnet metals essential for the clean energy transition
The Maiden JORC Resource of 1.7Bt is a major milestone for Resouro’s flagship Tiros project and demonstrates the company’s potential to be a major player in the strategically vital South American critical minerals sector.
Very few rare earths projects globally have a total resource of more than one billion tonnes and the JORC estimate places Resouro in a very favourable position with better-known Brazil-focused plays in the critical sector.
Large scale with high grades
Along with its scale, Resouro’s (ASX:RAU) Tiros resource sits at the top of the totem pole when it comes to grade as well, averaging 3900 parts per million total rare earth oxides and 1100ppm magnet rare earth oxides.
The MREO component contains high-value magnet metals neodymium, praseodymium, terbium and dysprosium, known by their periodic table signs of Nd, Pr, Tb and Dy. These are essential for the clean energy transition, while the resource also contains an average grade of 12% titanium dioxide.
Within that is a very high grade domain of 120Mt at 9000ppm TREO, containing 2400ppm MREO and 23% TiO2.
The combined measured and indicated resources represent over half of the inventory at 1Bt at 4050ppm TREO, containing 1120ppm MREO and 12% TiO2.
Resouro president and founder Chris Eager said: “Completion of our maiden JORC-compliant mineral resource estimate for the Central Block of the Tiros Rare Earth project marks a pivotal moment for Resouro Strategic Metals.
“The 1.7Bt measured, indicated and inferred resource is contained in a flat-lying, consistently thick, near-surface and highly weathered clay-like material.
“We consider that the average resource grades of 3900 ppm TREO, 1100 ppm MREO and 12% TiO2 are well above average for this style of deposit.
“The resource has a discrete domain containing 120Mt at 9000 ppm TREO containing 2400 ppm of MREO and TiO2 of 23%, which indicates the potential for the Tiros Project to be mined at a high grade in the initial years of production.
