A Cu occurrence/prospect located in sec. 22, T11S, R7E.
Mineralization is an ore zone hosted in welded tuff. Alteration includes quartz-sericite-pyrite (?).
Chrysocolla shows. To the south, the gossan turns to pyritic. Here it is chalcocite (?). There is no quartz veining, and the sulfides appear to be disseminated and on fracture surfaces. The alteration is difficult to type. Alteration is obvious but the key minerals are not obvious or easily discernable by hand lens. A slight bleaching along some fractures suggest sericite-pyrite without quartz introduction.
