Also see . . . Calvert Property (pdf). Excerpt:
The Calvert Property is located approximately 55 kilometres west of the city of Thunder Bay, Ontario. Access is by travelling 12 kilometers on a well-maintained all-weather road from Highway 590. Recorded previous work in the area dates back to the 1950’s, however exploration at the time was for iron ore. The current claim block and surrounding properties only started to receive attention after the discovery of high-grade massive sulfide boulders in the area by the OGS, the Stares Brothers and Dan Calvert. Gold-rich VMS boulders discovered in 1996 led to the discovery of a glacial dispersal train of boulders that seemed to emanate from a 1200 metre long conductive zone shown on the OGS 1991 Shebandowan geophysical survey. One boulder in particular assayed 0.6% Cu, 12.0% Zn, 4.44% Pb, 359 g/t Ag, 5.54 g/t Au.(Submitted on April 2, 2024, by Cosmos Mariner of Cape Canaveral, Florida.)
