The Mary-O showing is located approximately at 945 metres elevation immediately north of the confluence of St. John Creek with Beaverdell Creek, 8 kilometres northeast of Beaverdell, British Columbia.

The showing lies in an area of considerable exploration and mining activity since the early 1900s. Chalcopyrite on Knob Hill, at the head of Beaverdell Creek, was found, staked and developed as early as 1901. Other mineral occurrences (Observatory, 082ESW237) were discovered and explored to the west on King Solomon Mountain.

The hostrocks in the vicinity of the Mary-O showing are Permian Wallace Formation greenstone, quartzite, greywacke, limestone and locally paragneiss. These lithologies form roof pendants surrounded by granodiorite of the Jurassic Westkettle batholith. Latite and dacite dike intrude these older lithologies.

An old abandoned pit was discovered at the Mary-O showing. The average assay values of samples from this pit were 21.1 grams per tonne gold, 24.7 grams per tonne silver, 2.18 per cent copper, 0.12 per cent zinc, trace lead and 0.0096 per cent molybdenum (0.016 per cent MoS2) (Assessment Report 3740). Several molybdenum-rich outcrops were noted and sphalerite was observed in float.

During 2007 through 2009, Intigold Gold Mines Ltd. completed programs of rock and soil sampling and am airborne geophysical survey on the area as the Beaverdell property.
