The Old Alameada 5 occurrence is located at an elevation of approximately 1650 metres on a south-facing slope of Swakum Mountain, approximately 900 metres west- orthwest 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, shallow pit or shaft exposes a breccia consisting largely of limestone fragments in a tuffaceous matrix. The rocks are part of the Upper Triassic Nicola Group. Sparse pyrite occurs in the breccia; tetrahedrite and galena are also evident.
Work History
In the late 1910s, a 2.4-metre deep pit was excavated on the northeast portion of the Old Alameada No. 5 (L.4503) 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 and 1984, Pacific Northwest Geotech Ltd. completed a soil sampling program on the area immediately west and south of the occurrence as the New Alameda and Dam claims . In 1986, Atlar Resources Ltd. completed a program of geological mapping, geochemical (rock and soil) sampling and ground magnetic and electromagnetic surveys on the area immediately south of the occurrence as the Corona-Bob property. 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. A rock sample (TWS-1) from the occurrence area yielded 2.80 per cent copper (Assessment Report 25744). 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.
