Work History
Staked as Judy cl (76505) in Jun/64 by Cassiar Asbestos Corp L, which explored with bulldozer trenching in 1964, mapping and a magnetic survey in 1966 and bulldozer trenching in 1970.
Capsule Geology
Chrysotile fibre up to 6 mm long occurs in a serpentinized ultramafic body within an area about 600 m long by 300 m wide. The ultramafic body occurs in graphitic schist of the Nasina Series and is mostly covered by thin overburden. Trenching near the southwest contact exposed very low grade to barren serpentinite. Quartz-carbonate alteration is common on the east side.
