The Old Evelynn occurrence is located near the southwest end of a small un-named lake on Swakum Mountain and approximately 750 metres northwest of the north end of Shuta 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.

The occurrence area lies on the contact zone between volcanic and sedimentary sequences of the Upper Triassic Nicola Group. An adit was driven on a garnet-epidote skarn zone approximately 2.5 metres in width near the portal. Low-grade mineralization occurs as narrow streaks of galena in andesite adjacent to a limestone band. Pyrite and sphalerite are also present. Near the end of the adit is a 2- to 5-centimetre wide quartz vein in highly sheared andesitic country rock. The vein strikes north and dips west at a very low angle; very minor sulphide mineralization is evident.

Work History

In the late 1910s, an adit was driven for approximately 24 metres on the occurrence. A water-filled, 3-metre deep, winze is reported to be located approximately 6 metres from the adit portal.

In 1972 and 1973, Hesca Development Corp. Ltd. completed a program of rock, silt and soil sampling on the area immediately east of the occurrence as the Kay and Lyn claims of the Swakum Mountain property.

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

In 1981, S. Kelly completed a soil sampling program on the area immediately west of the occurrence as the Old Complex claims. In 1983 and 1984, Pacific Northwest Geotech Ltd. completed soil sampling programs on the area. Also in 1984, Mag-Ty Resources Ltd. prospected the area. 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 as the Corona-Bob property.

In 1998, Ahura Mining Ltd. prospected and sampled the area as the How 1-10 and Corona claims. A rock sample (TWS-5), taken south of Revelle Lake and approximately 2 kilometres east of the occurrence, yielded 0.80 gram per tonne gold and 0.24 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.

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.
