The Old Alameada 3 occurrence is located on a north-northwest–facing slope of Swakum Mountain, approximately 1.5 kilometres northwest of Dartt Lake.

The area is underlain by undivided volcanic rocks of the Western Volcanic facies of the Upper Triassic Nicola Group and fine clastic sedimentary rocks of the Lower to Middle Jurassic Ashcroft Formation, which have been intruded by Upper Triassic to Lower Jurassic dioritic rocks. See the Old Alameada (MINFILE 092ISE094) occurrence for a regional geology summary of the Swakum Mountain area.

Locally, a shaft intersects an unmineralized 2-metre wide quartz vein striking 030 degrees and dipping steeply northwest within Upper Triassic Nicola Group andesite. A narrow sulphide streak is present on the hangingwall side of the vein; masses of copper sulphides also occur across 60 centimetres near the footwall.

A select sample from the vein is reported to have yielded 8.2 grams per tonne gold (Property File 10630).

Work History

In the late 1910s, a shallow, 5.4-metre long, shaft was sunk in the northeast corner of the Old Alameada No. 3 (L.4505) Crown grant.

In 1969, Zulco Explorations Ltd. completed a 2.2 line-kilometre induced polarization survey on the area as the Alameada property.

In 1972, Adar Resources completed a 7.6 line-kilometre ground magnetic survey on the area immediately north and east of the occurrence as the LO claims. The following year, Adar Resources completed a program of diamond drilling, totalling 150 metres, percussion drilling, totalling 144 metres, soil sampling and ground magnetic and electromagnetic surveys on the Amigo, Lo and Old Alameada claims.

In 1979, the area immediately south of the occurrence was prospected by L. Trenholme as the Dartt 1-2 claims.

In 1980, G. D’Angelo completed a soil sampling program on the area as the Old Alameda claims. In 1981, Pacific Northwest Geotech Ltd. completed a soil sampling program on the area immediately west of the occurrence as the New Alameda claims. In 1987, Lacana completed a program of geological mapping, geochemical sampling and geophysical surveys on the area. In 1988, International Corona Corp. completed a program of trenching and 11 diamond drill holes, totalling 800.1 metres, on the area immediately north of the occurrence as the Petrie property.

In 1998, Ahura Mining Ltd. prospected and sampled the area immediately south of the occurrence as the How 1-10 claims. The following year, a program of geological mapping, rock sampling and a 27.2 line-kilometre ground electromagnetic survey was completed on the claims. In 2000, Ahura Mining completed a program of geological mapping and geochemical (rock and soil) sampling on the How property. A rock sample (SK-20) from a 1-metre wide rusty shear zone hosting pyrite, chalcopyrite and arsenopyrite associated with silica and epidote, located approximately 300 metres west of the shaft, yielded 0.262 per cent copper, 16.4 grams per tonne silver and 0.328 gram per tonne gold (Assessment Report 26468).

In 2010 and 2012, Pan Andean Minerals Corp. completed programs of soil sampling on the area immediately east of the occurrence as the Dartt Lake claims.

During 2011 through 2016, Plate Resources Corp. completed programs of geological mapping, geochemical (rock and soil) sampling, airborne and ground geophysical surveys and diamond drilling on the area as apart of the Lucky Mike property.
