(Shirley Concession)
The Shirley concession (296 km2) located in the Bacanuchi in northern Sonora, Mexico covers a very impressive color anomaly likely caused by hydrothermal alteration and oxidization of sulfide minerals exposed to surface weathering. The Bacanuchi area is known for its past production from artisanal mines (Cu, Au & Ag). The CRM airborne magnetic dataset details the Bacanuchi area to be within the same productive batholithic rocks that hosts the Cananea and the Maria producing mines. Additionally, there are several well defined magnetic "low" features within the Bacanuchi magnetic dataset which could indicate the hydrothermal destruction of magnetic minerals.
The gold potential has never been assessed in light of modern ideas and the porphyry copper potential may not be completely evaluated by previous workers. The property is located 25 km northeast from Santa Gertrudis and 35 km south of Cananea, a world-class porphyry copper deposit located 40 km south of the US/Mexico border.
