McNary Project

The McNary project is situated 15 km southwest of Prescott, Arizona, and encompasses 31 BLM claims.


It lies just 2 km west of a significant copper deposit with 228 million tonnes at 0.4% copper. 


The site’s accessibility is enhanced by its proximity to major highways, rail networks, and an electric power grid, all within 5 km.


Historically, the project has reported high-grade gold, with average grades reported at 8.5 g/t and peaks up to 78 g/t. 


Five former gold, copper, and zinc mines are located within a 5 km radius. 


Arizona’s reputation as a mining-friendly jurisdiction is well known.

Property history

The McNary Gold Mine’s origins trace back to around 1889, marking it as a significant historical site in Arizona’s mining landscape.


The mine was operational until 1930, with historical records indicating a production of approximately 1600 ounces of gold.


The property has undergone several ownership changes, initially staked by Redline Mining Corporation in 2017, and later acquired by Crown Minerals.

Geological setting

The McNary Gold Mine Project is situated within the Yavapai Formation in Yavapai County, Arizona. This formation is characterized by Precambrian metamorphic rocks and related intrusives, reflecting a complex geological history.



Age and Formation: The rocks in the area date back to around 1800 million years ago (Ma), indicating their formation in an ancient island arc environment. This timeframe places the geological features in the Proterozoic eon, a period known for significant crustal growth and tectonic activity.



Accretion to North American Craton: These geological formations were later accreted to the North American craton around 1200 Ma. The accretion process involved the collision and amalgamation of the island arc with the continent, leading to further geological complexity and diversity in mineral deposits.



Metamorphic and Intrusive Characteristics: The metamorphic nature of the rocks, coupled with the presence of granitic intrusions, provides a unique geological canvas. Such settings are often conducive to various mineralization processes due to the interaction of different rock types and the influence of intrusive events.





The McNary Gold Mine exhibits a distinctive pattern of mineralization, primarily characterized by a gold-bearing quartz-tourmaline vein.


Gold-Bearing Vein


Brecciation Events: The vein has undergone post- or syn-mineral brecciation, indicating that it has been affected by geological processes after or during the mineralization. Brecciation, involving the breaking and cementing of rocks, often enhances the permeability and porosity of the rock, potentially aiding in further mineral deposition.


Precambrian Mineralization Event: The mineralization is believed to be a Precambrian event, as the veins are found only in stocks dating back to circa 1200 Ma. This timing suggests that the mineralization occurred during or shortly after the accretion to the North American craton.


Associated Alteration: Alteration associated with the vein includes primarily fine-grained white mica. Such alteration patterns are indicative of hydrothermal processes and are commonly associated with gold deposits.
