• Measured and indicated resources at Resouro Strategic Metals’ Tiros titanium and rare earths project increase by almost 37%

• Total Resources have been lifted to 1.4 billion tonnes at 12% titanium dioxide and 4000ppm total rare earth oxides

• Within that is high-grade zone of 104Mt at 23% TiO2 and 9100ppm TREO

 

Special report: As trade tensions between the US and the world’s major critical minerals supplier China spiral, Resouro Strategic Metals has released an update to its already globally significant Tiros titanium and rare earths project.

In news that highlights Brazil’s potential to step into the critical minerals breach, the higher-confidence measured and indicated resources at Resouro’s (ASX:RAU) Tiros Project have been upgraded by almost 37% to 1.4Bt. That’s up from the 1Bt in the maiden mineral resource estimate Resouro released last July.

With total measured and indicated resources grading at 12% titanium dioxide and 4000ppm total rare earth oxides, the update confirms the project’s position as not just one of the world’s largest but also one of the highest grade clay hosted rare earths and titanium projects.

The results additionally highlight a very high-grade mineralisation zone, which includes total resources of 104Mt at 23% TiO2 and 9100 ppm TREO.

The high-grade zone will be the focus of the Resouro’s initial scoping study and subsequent feasibility studies, along with the economic assessments required to advance the project.

The studies are being conducted with industry leading partners and the support of organisations in Brazil’s mining friendly Minas Gerais state.

The update follows the results from additional assays received from a 46 infill and resource expansion drill program conducted in 2024.

Large tonnage, high grade resource

There’s still plenty of potential to further grow the resource as the MRE covers only 8% of Resouro’s total tenement holding area. Another positive for the project is that the mineralisation has so far been found to be homogenous and close to surface.

Resouro’s Executive Chairman, Chris Eager, said: “The Tiros project continues to deliver amazing results, in terms of large tonnage of high TiO2 and TREO grades within continuous near surface layer of friable material with constant grade and thickness.

“The next step is to work toward a proved and probable minable reserves from the 1.4 billion tonnes measured and indicated resource.

“The flat-lying layer of friable material at Tiros translates to ease of mine planning with no drilling or blasting and a low stripping ratio.

“This facilitates environmentally friendly cut and fill mining with continuous rehabilitation, equating to low mining costs with consistent supply of tonnes and grade to a processing plant.

“Designing and optimising a plant for one consistent feed would assist in maintaining consistent recoveries and processing costs.”
