The ML showing is in the Mons Creek area of the Chilcotin Plateau, approximately 13 kilometres north of Gaspard Lake and 77 kilometres southwest of Williams Lake, B.C.

The showing consists of coarse chalcopyrite grains in a narrow quartz vein (2 to 3 centimetres wide) near the contact of altered hornblende granodiorite with biotite granodiorite. Alteration minerals include epidote, sericite and potassium feldspar. Altered boulders of granodiorite containing disseminated chalcopyrite have also been found within the area covered by the ML claim group.

The ML showing occurs within the Mount Alex Plutonic Complex consisting of granodiorite, quartz diorite, quartz monzonite and diorite of probable Middle Jurassic age and overlain by basalt of Miocene to Pleistocene age. The plutonic complex is interpreted to intrude older rocks of the Carboniferous to Jurassic Cache Creek Group which are exposed to the east of the complex. In the Mons Creek area, the Mount Alex Plutonic Complex consists of a weakly to strongly foliated, chloritized quartz monzodiorite, quartz diorite and granodiorite. Most of the Mons Creek area is covered by extensive glacial overburden.

In 1969, Royal Canadian Ventures Ltd. completed a magnetic and VLF-EM geophysical survey and a soil geochemical survey resulting in a copper anomaly approximately 700 metres by 180m metres in size (Assessment Report 2127). In 1970, Royal Canadian Ventures Ltd. followed up with an induced polarization (IP) survey resulting in anomalous sources at depths of approximately 100 metres.

The area was explored in 1979 by Pancanadian Petroleum Ltd. in search of uranium sources. In 1993, Winslow Gold Corp followed up with a sampling program over a stream geochemical copper-gold anomaly resulting from a 1992 GSC regional geochemical survey.

In 2010 and 2011, Strongbow Exploration Inc. carried out programs of silt, soil and minor rock sampling as well as prospecting in the Mons Creek area. In 2017, B.Kreft and son conducted soil and rock sampling in the vicinity of the ML showing. Rock samples encountered up to 0.11 per cent copper from angular till samples of quartz-chalcopyrite veining.
