Metamorphism Type: Contact
Metamorphism Grade: Amphibolite
Dec 07, 2005 (S Fumerton) - A number of parallel metamorphosed shear zones cut the outcrop and contain quartz veins.

Jan 28, 2015 (S Fumerton) - The host rock is a very coarse grained massive mafic flow. Within this rock the subhedral hornblende grains have undergone some porphyroblastic growth and there is a weak lineation to these crystals. Epidote rich veins up to 20cm thick form an open stockwork in the coarse grained flow. Intruding the mafic flow are a number of felsite dykes that form an open stockwork and range between 4 and 400 cm thick. These dykes have irregular shapes en-echelon off-sets and horns. The smaller dykes are also zoned with fine grained to pegmatitic phases whereas the larger bodies tend to be more uniform and fine grained. Clear, coarse grained quartz veins locally occur along the axis of these dykes. The main quartz vein system occurs in a finely banded - foliated unit which has been interpreted as a shear zone that has recrystallized under amphibolite facies metamorphism. This interpretation is based on the prevalence of fine grained amphibole in the unit. At the southwest end of the vein system the wall rock in these shear zones is strongly altered to chlorite.

Dec 07, 2005 (S Fumerton) - The quartz vein system has a banded appearance or consists of a set of thin parallel quartz veins. Locally, where the vein is up to a metre thick, there are thin seams of chlorite altered wall rock within the veins. Low concentrations of very fine grained pyrite are disseminated in the quartz veins. Also rust spots related to weathering of sulphides occur in greater concentrations within the wall rocks adjacent to quartz veins. Visible gold has been reported.
Jan 28, 2015 (A Wilson) - Channel sampling of the vein in the 1930's returned low gold values. Chip samples collected by Cyril Knight Prospecting Co. returned assays from 0.001 oz/t Au and 0.01 oz/t Ag across 5 feet to 0.130 oz/t Au and 0.03 oz/t Ag across 2 feet. Chip samples taken by the OGS in 1993 returned values of 0.01 g/t Au and 1.4 g/t Au. Grab samples collected by Newmont Exploration in 1982 returned 0.067 oz/t Au from a cherty unit.

Notes: There are several old camp sites and a dock on the shore of Ridley Lake. One camp consisting of a shack tent is in ruins under a blown over tree. Another camp off the shore line consists of plywood cabins in good repair.
