- The showing is located slightly east of the south end of a narrow, northeast-trending lake which is located 3.62 km (2.25 miles) southwest of the south tip of Smalley Lake.
The showing area, as mapped by R.J.C. Munday in 1972, is underlain by unit F2 or buff-colored, hypersthene-rich, granulite facies felsic gneiss which is in contact with a northeast-trending band of Mudjatik Domain unit B2 of graphitic, sillimanitic and garnetiferous biotite gneiss.
The felsic gneisses and supracrustals in the showing area have been metamorphosed and folded during at least two phases of deformation. The D1 event contorted the rocks into a series of sub-horizontal, open, megascopic folds with an axial planar fabric that resulted in a regional foliation. During the D1 event, the rocks were metamorphosed to between amphibolite and granulite facies. The later D2 event produced a series of northeast-trending, symmetric, open folds. During the D2 event, rocks were metamorphosed to between amphibolite and granulite facies.
The showing occurs on a 0.24 km (0.15 mile) long by 15 metre (50 foot) wide, low ridge of biotite-quartz-feldspar psammite which consists of 70-90% quartz and 10-30% feldspar. The biotite is present as finely disseminated flakes.
Yellow uranium stain occurs as infillings in minute fractures within the psammite. Scintillometer readings at the showing reached 8000 cps. Two grab samples returned the following values:

- Exploration History
- 9/18/1992 The area was first covered by Darling Hydrocarbons Ltd. and Yukon Geothermal Co. Ltd. Permit No. 1 on 16 January 1969. In 1969 they flew an airborne geophysical survey (AF 74B16-0001). No other work was completed and the permit was dropped June 1, 1970.
The area remained open until the showing area was staked as CBS 3558 in April of 1971. No work was completed on the claim and it lapsed on 1 July 1972.
The showing was next staked as CBS 4547 on 18 September 1975 by E & B Explorations Ltd. In 1977, an E & B Explorations-Uranex Ltd. partnership completed reconnaissance scintillometer prospecting and lake sediment sampling on the property (AF 74B09-0007 and 74B16-0004). This work resulted in the discovery of the mineralization which constitutes this showing.
In 1978, the partnership completed an airborne EM, magnetic, and radiometric survey over the property (AF 74B16-0006 and -0016) and follow-up geological mapping, radiometric prospecting, and ground HLEM and magnetic surveys on the showing grid (AF 74B09-0009).
In 1979, E & B completed prospecting, geological mapping, radiometric, soil and radon-gas-in-soil surveys (AF 74B09-0021), ground EM, and magnetic surveys (AF 74B09-0022) on the Kenting grid.
No further work was done and the property lapsed 1 February 1985.
