Ameriwest Completes 3D Geological Model Defining High-Grade Copper Shell Along with Two Additional Zones at the Bornite Project

Ameriwest Critical Metals Inc. has achieved a significant milestone in advancing its Bornite Copper-Gold-Silver Project in Oregon with the completion of a preliminary 3D geological model by APEX Geoscience Ltd. The model provides a modern framework for understanding the deposit's geometry and has identified three distinct mineralization domains within the vertically-standing, cigar-shaped breccia pipe system.

The most significant finding is a high-grade copper shell averaging approximately 2.4% Cu located on the outer margins of the pipe, surrounded by a sheeted vein zone averaging 0.9% Cu and an interior pipe domain averaging 0.60% Cu. These grades are based on historical drilling and surface data from the 1970s-1990s, which the company is now systematically modernizing. The model has also identified priority drill holes for relogging and target areas on the southeast and northwest flanks for expansion drilling.

A key strategic element of Ameriwest's approach is the planned incorporation of broader multi-element geochemical analysis in future work programs. Given that comparable breccia pipe systems have yielded additional metals including molybdenum and tungsten, this expanded analytical approach could identify previously unrecognized by-product or co-product opportunities that may enhance the project's overall economics.

The company plans to prioritize expansion drilling over infill drilling following validation of historical data, focusing on areas where contacts between andesite and quartz diorite remain uncertain. This strategy aims to expand the volume of mineralized material to support a deeper future pit shell and capture additional mineralization associated with the pipe-style system. The 2026 work program represents a disciplined approach to advancing the project toward resource-stage evaluation using modern geological interpretation and expanded geochemical understanding.
