- The showing consists of several diamond drill holes completed to intersect conductors outlined by previous surveys. The drill holes were completed east of the east shore of Alexander Bay on Pitching Lake.
The showing is hosted within the same band of folded unit 2 hornblende gneiss, hornblende-biotite gneiss, and calc-silicate gneiss which hosts the Pitching Lake Showing (SMDI 0801). This narrow band of gneisses wraps around the edge of a large body of granodiorite which occupies the core of a regional syncline. L. Beck described the host rocks, further to the south at the Pitching Lake Showing, as a series of chloritized and banded hornblende gneisses (amphibolites) with interbanded calc-silicate horizons and graphite-bearing biotite rich gneisses. Later geologists have interpreted this host package to represent a series of mafic to intermediate, possibly re-worked tuffs and flows intercalated with locally graphitic metasedimentary wackes, and calc-silicate horizons.
The drill holes intersected disseminated pyrite and pyrrhotite in low to high amounts over tens of feet with narrow bands of up to five feet of massive pyrrhotite and minor pyrite in north-trending Archean metasedimentary garnetiferous biotite-hornblende gneisses cut by pegmatite. Graphite occurred commonly in minor amounts throughout the section and especially with the more massive sulphides.

- Exploration History
- 7/14/1988 In 1957, Gresham Exploration Ltd. completed an airborne EM survey over the showing area (AF 63M05-0005).
In 1965, Selco Exploration Company Ltd. conducted an airborne electromagnetic survey over the Keg-Pitching Lakes area. This was followed by the staking of CBS 777 to cover anomalies located on the northwest shore of Pitching Lake (Alexander Bay). Follow-up ground electromagnetic surveys were conducted and, in 1966 diamond drilling of 7 holes totalling 1806 ft (550.5 m) was reported on the outlined conductors.
No further activity was reported in the area and CBS 777 was allowed to lapse in 1968.
On 27 February 1984, Claude Resources Inc. staked the showing area as CBS 7558. Between 1986 and 1987, Claude completed mapping, ground geophysics and rock and overburden sampling to the southwest of the showing around SMDI. 0801 (AF 73P08-0038,0039).
In 1987, World Geoscience Corporation flew a high resolution VLF-EM and magnetic survey which covered the showing (AF 63M05-0030).
