Arizona Metals’ Kay PEA Gives Shape to a High-Grade U.S. Polymetallic Development Path

Arizona Metals has moved the Kay Mine Project into a more defined development frame with the release of a preliminary economic assessment for the past-producing VMS system near Black Canyon City in Yavapai County.

The project remains at a study stage but the PEA gives the market a clearer view of how the deposit could be mined, processed and scaled. 

The proposed mine plan is built around underground longhole open stoping, with a single portal south of the surface infrastructure area. The PEA outlines average mine feed of 1,918 tonnes per day and commercial throughput of 0.7 million tonnes per year, with ramp-up to full throughput over nine months before a seven-year steady operating period and a later ramp-down. 

The current mineral resource gives Kay its technical weight. The underground resource includes 9.28 million tonnes grading 1.39 g/t gold, 27.6 g/t silver, 0.97% copper, 0.33% lead and 2.39% zinc in the Indicated category. A further 0.86 million tonnes is classified as Inferred, grading 1.06 g/t gold, 15.4 g/t silver, 0.87% copper, 0.20% lead and 1.68% zinc.

Kay’s significance lies in the combination of grade, access and commodity mix. The project is located close to Black Canyon City, about 69 kilometres north of Phoenix, with road access, existing disturbed ground and a mineralised system defined from near surface to at least 900 metres depth. It is also exposed to multiple metal markets rather than relying on one commodity, giving the project broader relevance in a U.S. critical and precious metals setting. 

The study remains preliminary and does not establish mineral reserves. That distinction is important for those assessing the project’s next phase.

Arizona Metals still has to convert study work into more advanced engineering, permitting and financing outcomes. Even so, the PEA shifts Kay from a drilling-led story toward a more structured development proposition with underground scale, polymetallic value and continued exploration upside.
