Extract from MINFILE Occurrences: 092L 328 and 092L 329
Development status: Prospect
Name: LEMARE 1, CAM
The area is underlain entirely by Lower Jurassic Bonanza Group intermediate to felsic volcanic flows and pyroclastics that have undergone regional low grade zeolite and laumontite grade metamorphism. Dark green andesite flows, dacite lapilli tuffs and rhyodacite crystal tuff are intruded by sporadic andesite dykes and bisected by steeply dipping faults.
Chalcopyrite, pyrite, sphalerite, malachite and azurite, associated with fractures, are present for 600 metres along a road cut. Assays range from 0.2 to 1.4 per cent copper (Assessment Report 8593). Similar mineralization was located on a road cut 400 metres to the southeast.
MINFILE No 092L 329 (LEMARE 2, CAM):
The area is entirely underlain by Lower Jurassic Bonanza Group intermediate to felsic volcanic flows and pyroclastics. The rocks have undergone low grade metamorphism as exhibited by the prescence of zeolite and laumontite.
At the occurrence, heavily pyritized flow banded rhyolite, dacite tuffs and flows are intruded by 1 to 2 metre thick andesite dykes. Strong faulting and fracturing are present. A zone of finely disseminated pyrite, occasionally with chalcopyrite, bornite and malachite on fractures, has been traced for 300 metres.
Chip samples assayed up to 0.14 per cent copper. Grab samples returned values to 0.49 per cent copper (Assessment Report 8593).
