Mineral Resource Estimate

Empire Metals will engage with investors at the Ignite Investment Summit in Hong Kong and LME Week in London during October 2025. Management will provide updates on the Pitfield Project following the maiden Mineral Resource Estimate. Discussions will focus on the MRE’s implications, project economics, and the path to commercial production of its substantial titanium resources (2.2 billion tonnes grading 5.1% TiO₂). An updated corporate presentation is available on the company website.

Red Pine Exploration Inc. has begun surface trenching and geological mapping at its Wawa Gold Project, aiming to better define gold mineralization for potential open-pit mining. This program targets the North Pit area, where drilling indicates high-grade gold intersections. Data from the trenching will inform an updated mineral resource estimate and preliminary economic assessment (PEA), expected in the first half of 2026. The company is also conducting environmental baseline studies. Red Pine adheres to a strict QA/QC protocol throughout exploration.

Empire Metals released an updated presentation on the Pitfield Project, a titanium prospect in Western Australia, ahead of the maiden Mineral Resource Estimate (MRE) expected in October 2025. Airborne surveys indicate a large anomaly, and drill results show consistent TiO₂ grades. An Exploration Target estimates 26.4-32.2 billion tonnes at 4.5-5.5% TiO₂. The company aims to develop high-value titanium products on-site and also has exploration projects in Australia and Austria. The presentation is available on the company’s website.

Omai Gold Mines announced a significant increase in its Mineral Resource Estimate (MRE) at the Omai Gold Property in Guyana. Indicated Mineral Resources rose 7% to 2.1 Moz Au at 2.07 g/t Au. Inferred Mineral Resources jumped 92% to 4.4 Moz Au at 1.95 g/t Au. The Wenot Deposit contains 970,000 oz gold Indicated and 3.7 Moz Inferred, while Gilt Creek holds 1.15 Moz Indicated and 665,000 oz Inferred. A drilling campaign is planned for resource expansion, targeting a Feasibility Study by late 2026. Existing infrastructure supports reduced development costs.

Orosur Mining (TSXV:OMI) announced exceptional drilling results at its Pepas gold prospect within the Anzá Gold Project in Colombia. Highlights include hole PEP047 with 104m @ 6.61 g/t Au from the surface. The company is rapidly advancing towards a NI43-101 compliant Mineral Resource Estimate (MRE) by year-end, drilling approximately one hole per week with 3-4 day lab turnaround. Orosur plans additional studies on metallurgy, mine planning, and logistics to expedite Pepas’s development post-MRE.
