The showing, also referred to as 50-RR-15, is located 1 mile (1.6 km) due north of the tip of the eastern arm of Sylvester Lake.  Zone 50-RR-20 is located 0.75 miles (1.2 km) east of showing 50-15.
     The area of the showing is underlain by granite and granite gneisses containing numerous mafic bands such as amphibolites and quartz-rich chlorite-epidote rocks.  The general strike is northeast and the area is cut by strong northeast and east lineaments which are probably fault zones.
     Mineralization occurs in Showing 50-RR-15 within a series of closely spaced parallel fractures in the mafic rocks near the granite-mafic contact.  A northeast-trending zone 60 ft (18.3 m) long and 3 to 4 ft (0.9 to 1.2 m) wide was trenched.  Sampling yielded a maximum assay of 0.55% U3O8 equivalent from a grab sample.
     Zone 50-RR-20 occurs in fractured granitic material with chlorite bands on the edge of a muskeg that occupies a linear depression trending northeast.  The host rocks display intense red alteration.  Chip sampling of weathered material containing possible pitchblende yielded 0.16% U3O8 equivalent.

     Showing 50-RR-15 was found in 1950 by Athlodge Uranium Mines Ltd. on the RR Concession.  Geiger and geological surveys were conducted and promising areas stripped.
     Zone 50-RR-20 was also located in 1950.
