It is located about 19 km (12 mi) northwest of the hamlet of Marten River on an island in north-central Cross Lake.

The mine was discovered in 1907 when attention was focused there by the discovery of a quartz vein in rocks that closely resembled those in the town of Cobalt further north, which was undergoing a silver rush at the time.

Development consisted of small open pits and sinking of a 23 m (75 ft) inclined shaft along the quartz vein.

[1] In 1955, Cross Lake Mining Company Limited dewatered the shaft for examination and four diamond drill holes were created from the surface.

It was evident that good mineralization had been encountered in the shaft, judging from the lumps of high-grade ore found lying in the muck, consisting of copper and galena, and some was observed on the waste rock dump.
