- Geological Details
- The showing, which is located approximately 200 m (656.2 ft) north of the northwest end of Douglas Lake, consists of four pits that occur within northwest-trending, sheared basaltic volcanics of the Amisk Group.
Four pits were excavated on the showing and samples returned the following assays:
Pit No. Au (oz./ton) Ag (oz./ton) % Cu Width ft (m)

In 1991, D. Thomas geologically mapped the showing area as being underlain by unit 5 and 5a. Unit 5 is an series of aphyric to plagioclase-porphyritic intermediate to mafic flows and unit 5a is a series of pillowed mafic to intermediate flows which contain abundant quartz amygdules.

- Exploration History
- 6/27/1988 Between 1953 and 1954, Hudson Bay Exploration and Development completed an electromagnetic survey over the showing area.
In 1967, the showing area was covered by MARS 1 to 24 claim group. In this year, R. Studer conducted a regional EM survey for Meridian Mining and Exploration Company Limited that covered the showing area (AF 63K12-0063). No anomalies were detected in the showing area.
In 1972, W.J. Reid dug 4 pits on the JET 7 and 9 and KAY 6 claims, a few hundred feet north of Highway No. 35 at the northern end of Douglas Lake (AF 63K12-0030). Copper mineralization was reported from pit 1 on the KAY 6 claim and from pit 3 located on the JET 9 claim. The assays returned the values listed above. A further two trenches were completed in 1974.
