Ameriwest Critical Metals Inc. Completes 3D Geological Model Defining High-Grade Copper Shell Along with Two Additional Zones at the Bornite Project
Ameriwest Critical Metals Inc. announced that APEX Geoscience Ltd. ("APEX") has completed a preliminary 3D geological model (the "Model") for the Company's 100%-owned Bornite Copper-Gold-Silver Project in Oregon. The Project hosts a copper, gold and silver deposit located about 50 miles east of Salem, Oregon. The deposit is contained within a roughly cylindrical, vertically standing, cigar-shaped breccia pipe. Copper minerals, principally bornite and chalcopyrite, were deposited as part of the breccia matrix, mainly along the pipe's margins. Higher-grade mineralization is found on the pipe's outer shell, with lower-grade mineralization within the pipe's interior. APEX has completed a preliminary 3D geological model for Ameriwest's 100%-owned Bornite Copper-Gold-Silver Project in Oregon, providing a modern framework for advancing the deposit using historical drilling and surface data. The model will be used to guide 2026 technical work, including historical core relogging, drilling, expansion targeting, and future resource evaluation. Several mineralization domains identified: Modeling indicates that the Bornite system includes a higher-grade copper shell averaging approximately 2.4% Cu, surrounding an Interior Pipe averaging approximately 0.60% Cu, with an additional Sheeted Vein Zone averaging approximately 0.9% Cu. Ameriwest also plans to incorporate broader multi-element geochemical analysis in future relogging, re-sampling and drilling to evaluate potential additional metals that may not have been systematically assessed in historical work. APEX has identified priority historical drill holes for relogging to strengthen the geological interpretation and support future resource work, including holes CC15, CC17, CC26, CC29, CC03, CC09 and CC16. Following validation of historical data through a limited confirmatory program, the Company expects to prioritize expansion drilling over infill drilling, with target areas identified on the southeast and northwest portions of the modeled system. In addition, because historical work at Bornite was focused primarily on copper, gold and silver, the Company intends to incorporate broader multi-element geochemical analysis as part of any relogging, re-sampling and future drilling programs. This is important because comparable breccia pipe and tourmaline-breccia copper systems have also yielded other metals, including molybdenum, tungsten and other trace elements, that may not have been systematically evaluated in the historical database. By testing for a wider suite of elements, Ameriwest aims to build a more complete understanding of the Bornite mineralization system, which could help identify additional by-product or co-product opportunities and, if present, potentially enhance the overall economics of the project. There can be no assurance that any additional metals of economic significance will be identified.
