Location: The location of the O.K. prospect is based solely on small-scale map in Wright and Wright (1908). It probably is within 0.5 mile of the center of the NE1/4 section 17, T. 77 S., R. 89 E.
Geology: As described by Wright and Wright (1908), the O.K. prospect is a quartz vein 3 to 4 feet thick that strikes N75W; it contains chalcopyrite, pyrite, sphalerite, galena, and gold. Little work had been done on it then and apparently it has not been described since. The vein is at the contact between schist and limestone of the Wales Group of Late Proterozoic and Cambrian age (Eberlein and others, 1983; Brew 1996). Hedderly-Smith (1999 [Inventory]) suggests that the deposit may be similar to the quartz-breccia mineralization along the Kael-7 Mile Trend (CR188), as the prospect is well within that mineralized belt.
Workings: Little work had been done on this prospect in 1908 and apparently there has been none since.
Commodities (Major) - Au, Cu, Pb, Zn
