The Coronado occurrence consists of quartz veins hosted by Middle-Upper Jubilee Formation dolomites, slates and argillites close to a Cretaceous syenitic-monzonitic intrusive. The veins contain pyrite, chalcopyrite, malachite, tetrahedrite and traces of magnetite. The veins are discontinuous and are hosted by tremolitic dolomites. Thrust faulting occurs in the immediate area.

During 2005 through 2009, Ruby Red Resources Inc. completed programs of rock and soil sampling, geological mapping, trenching and a 4.5 line-kilometre ground electromagnetic (VLF) survey on the area. In 2010 and 2011, the area was explored as a part of the Dewdney Trail Gold project of PJX Resources Inc. Past exploration efforts on the showing included prospecting, soil geochemistry, rock sampling, VLF-EM, magnetic surveys, IP surveys, hand trenching, and diamond drilling.
