The MARG 1 showing is located about 17 kilometres west of Peachland, near Glen Lake.

The area is underlain by granodiorite of the Early Jurassic Pennask Batholith. Outcrops of Triassic-Jurassic Nicola Group sedimentary and volcanic rocks occur to the east. The Middle Jurassic Osprey Lake Intrusions occur to the south.

Trenching was apparently carried out by Don Agur of Summerland in the early 1960s to expose a potassic alteration zone. Subsequently, percussion drilling was reportedly carried out by Juniper Mines Ltd. and Maverick Mines. No reports exist of this work. Ian Sutherland completed a geochemical survey in 1979 and did some prospecting in 1982.

A strongly altered potassic zone occurs in granodiorite and contains chalcopyrite in fractures. The area is well fractured with major fractures trending northeast-southwest.

Assessment Report 7790 states that an average assay of 0.87 per cent copper came from a 125-metre trench from the early 1960s.

From 2013 to 2014, multiple small work programs were completed on the property containing the occurrence. Highlighted results from the work completed on the property include a new vein showing grading up to 1.5 grams per tonne gold, and 32 grams per tonne silver, and rock samples grading up to 0.11 percent copper (Chapman, J. (2017-10-11): NI 43-101 Technical Report on the Amarillo Property).

In 2016, Troubadour Resources Inc. completed an exploration program on the property containing the occurrence including soil and rock sampling, and 39.5-line kilometres of ground magnetic data. Results are described in detail in the report by Chapman.
