The Mercury 1 occurrence is located near the Tutizika River, approximately 7 kilometres west of the junction of the Mesilinka River, 95 kilometres northwest of the community of Germansen Landing.

Cinnabar reportedly occurs (Geological Survey of Canada Memoir 274, page 203) in carbonatized fault zones which are part of, or are related to, major northwest trending block faults which have displaced all the units in the area. The actual hostrocks were not reported but are thought to be of either the Permian Lay Range assemblage or the Upper Devonian to Permian Big Creek Group (S. Dudka, personal communication, 1993). Rocks in the area typically consist of argillite, shale, phyllite, limestone, sandstone, tuff, and gabbro. These two packages are in fault contact near their indicated location (Open File 1993-2).

In 1987, on behalf of Skylark Resources Ltd., geological mapping, prospecting, silt (4), soil (125) and rock chip (19) sampling was carried out on the Dolly 1, 2 claims which cover the Zip (094C 142), Stranger (094C 015), Mercury 1 and Mercury 2 (094C 042) showings.
