Core Viewpoint - Allied Critical Metals Inc. has announced a significant increase in the Mineral Resource Estimate (MRE) for its Borralha Tungsten Project in Northern Portugal, which is expected to advance towards a Preliminary Economic Assessment (PEA) targeted for Q1 2026, amid strong tungsten prices and increasing demand for critical raw materials [3][4][6]. Mineral Resource Estimate Update - The updated MRE for the Borralha Tungsten Project shows a substantial increase to 13.0 million tonnes Measured and Indicated (M+I) at 0.21% WO₃ and 7.7 million tonnes Inferred at 0.18% WO₃, compared to the previous estimate of 4.98 million tonnes Indicated at 0.21% WO₃ and 7.01 million tonnes Inferred at 0.20% WO₃ [4][6]. - The MRE is based on a cut-off grade of 0.09% WO₃ and does not include other potential mineralized deposits on the property [5][6]. Geological and Metallurgical Context - The Santa Helena Breccia is confirmed as a large, mineralized system with strong structural control and excellent lateral continuity, indicating significant potential for further resource growth [9][10]. - Existing metallurgical programs suggest a simple, low-cost gravity flowsheet with a recovery rate of approximately 75-85% WO₃, with potential by-products including copper, tin, and silver [10][11]. Strategic Importance - The Borralha Project is positioned as a critical asset in Europe, especially given the EU's reliance on tungsten imports from China, with over 80% of its tungsten supply coming from there [24][25]. - The project is aligned with the EU Critical Raw Materials Act and NATO strategic autonomy initiatives, emphasizing its importance in developing a secure domestic supply of tungsten [24][25]. Next Steps - The company plans to conduct further drilling campaigns in early 2026 to expand the resource base and support the upcoming PEA [7][12]. - Ongoing environmental and hydrogeological baseline programs are in place to facilitate the permitting process, with anticipated approvals expected in Q1 2026 [7][12].
