T he Old Alameada 1 occurrence is located in the northwest corner of the Old Alameada No. 1 (L.4506) Crown grant at an elevation of approximately 1600 metres on the north slope of Swakum Mountain.

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.

The occurrence lies at the contact between Upper Triassic Nicola Group limestone and volcanic rock and forms a zone 7 to 22 centimetres wide. The skarn zone consists of altered limestone with epidote, calcite, pyrrhotite, chalcopyrite and minor sphalerite.

Other zones of copper±gold-zinc mineralization are reported several hundred metres west and north-northwest of the shaft.

In 1972, a sample from a roadcut in the area of the Old Alameada 1 occurrence is reported to have yielded 0.21 per cent copper (Assessment Report 25744).

Work History

In the late 1910s, a vertical, 13.5-metre deep, shaft is sunk near the northwest corner of the Old Alameada No. 1 (L.4506) 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 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 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.

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.
