Classification: Confidential
Street: Survey samples received from the following claims/properties: Proffit (3), Cheek (2), Fender (2) and Stewart (5).
o&ietfjve Preliminary evaluation as potential talc source.
Results:
Attached table shows mineralogy estimated from X-ray diffraction scans.
Only one of the samples looked good - Steward nil. This sample was
from the composite used for flotation testing (Ref. 88-240). The test did not give a mineralgica!ly acceptable product.
Judging from the intense red color of the LOI residues from these ta lc s, they are all high in iron.
