- Target: open-pit leachable mineralization in granitic and metamorphic rocks
- Preliminary surface samples up 9.5 gpt Au
Montana Negra contains a series of gold prospects in Proterozoic age Pinal schist adjacent to a fluorite bearing granite. The concept target is orogenic quartz-gold veins under adjacent gravel cover. A significant placer deposit was mined historically in the streams draining the Montana Negra area.
