The North MDA occurrence is located approximately 1.9 kilometres east of the south end of Ketchan Lake and 1.4 kilometres southwest of Missezula Lake.

The region southwest of Missezula Lake is underlain by the Eastern volcanic facies of the Upper Triassic Nicola Group, comprising mafic to intermediate augite and hornblende porphyritic pyroclastics and flows, and associated alkaline intrusions. The intrusions vary from diorite to monzonite in composition and are thought to be comagmatic with the Nicola Group, ranging in age from Upper Triassic to Lower Jurassic. Much of the copper mineralization and associated alteration frequenting this portion of the Nicola Belt can be attributed to the emplacement of such intrusions.

Locally, chalcopyrite occurs together with magnetite and epidote in an elongate stock of fine-grained diorite, near its east end. Malachite occasionally accompanies this mineralization. The stock intrudes andesitic flows and pyroclastics of the Upper Triassic Nicola Group (Central Belt, Bulletin 69). The andesites exhibit epidote alteration accompanied by some weak copper mineralization in a poorly defined area extending up to 600 metres north and 300 metres east of the stock.

In 1985, a rock sample (88611) assayed 3.1 grams per tonne silver and 0.145 per cent copper (Assessment Report 14141, Drawing 13a).

In 2015, 21 samples were collected from the occurrence area, with 13 of the samples yielding greater than 0.1 per cent copper and values of up to 0.710 per cent copper, 6.5 grams per tonne silver, 0.481 gram per tonne palladium and 0.364 gram per tonne gold (Assessment Report 36184).

Work History

In 1972, Sheba Copper Mines Ltd. completed geological mapping, soil sampling and magnetic surveysin the area as the MDA claims.

In 1985, Vanco Explorations Ltd. completed a program of geological mapping and geochemical (rock and soil) sampling on the area as the Bloo, Climax and Thor claims. In 1987, a further program of rock and soil sampling was completed on the claims.

In 2004, Copper Hill Exploration Corp. completed a program of geological mapping and photogeological interpretation on the area as the Ketchan property.

In 2011, Moag Copper Gold Resources Inc. completed a program of soil sampling on the area as part of the Ketchan property. In 2013, West Cirque Resources Ltd. completed a program of geological mapping and rock sampling on the area as the Aspen Grove property. During 2014 through 2016, KZD Aspen Grove Holding Ltd. completed programs of prospecting, geological mapping and a 21.4 line-kilometre induced polarization survey on the Aspen Grove property. Also in 2016, Christopher Delorme completed a minor program of rock and soil sampling on the occurrence.
