Work History
Staked as Ram cl 1-48 (YA14243) in Nov/76 by Mountaineer Mines Ltd and optioned to Pan Ocean Oil Ltd, which explored with mapping, soil sampling and radiometric surveys in 1977 and 1978. Mountaineer changed its name to Canadian Mineral Corporation in 1979.
Restaked as Ram 1-20 cl (YB28672) in Jun/92 by a joint venture consisting of Pamicon Developments Ltd, Equity Engineering Ltd and Westmin Resources Ltd, which explored with limited sampling, prospecting and mapping in 1992. In Jan/94, the joint venture partners transferred 100% interest in the Ram claims to Westmin Resources, which then formed the Fairchild Joint Venture with Newmont Exploration Ltd. In Sept/94 the Fairchild Joint Venture contracted Pamicon and Equity to carry out preliminary mapping, stream sediment sampling and prospecting.
D. and J. Hajek staked Co cl 1-20 (YB65589) to the east in Jul/96.
Capsule Geology
The region is underlain by a metamorphosed and altered sequence of Early Proterozoic Wernecke Supergroup clastic and carbonate rocks (Fairchild Lake Group, Quartet Group and Gillespie Lake Group, from oldest to youngest) that are intruded by Early to Middle Proterozoic mafic sills and dykes, and cut by Middle Proterozoic hematitic Wernecke Breccia. According to Thorkelson (2000), Wernecke Breccia development is best modeled as a set of hydrothermal and/or phreatic breccias; brecciation being caused by explosive expanson of volatile-rich fluids. Hunt (2005) attributed Wernecke Breccia formation to periodic over-pressuring of dominantly basinal fluids, which lead to repeated brecciation of host strata and mineral precipitation. To the east, the Wernecke Supergroup is juxtaposed against younger rocks along the southeast-trending Richardson Fault array, which is interpreted to represent deep-seated, long- lived vertical structures that have undergone considerable vertical, and possibly right-lateral movement.
Exploration work carried out by Pan Ocean Oil Ltd found mineralization consisting of pitchblende, brannerite and chalcopyrite in fracture zones within breccia bodies cutting Wernecke Supergroup strata. Five specific zones and numerous small showings were found in a 1 400 by 2 100 m belt running north-south along the west side of the claim block. Chip samples ranged up to 0.91% uranium oxide (U3O8), and 0.38% copper across 2 m from a hand trenched zone on the southeast side of Ram Creek. Follow-up sampling in the same area in 1979 returned 0.10% uranium oxide (U3O8) across 1 m at a depth of 2 m.
Industry mapping shows the Ram claim group is underlain by complexly folded and faulted Wernecke Supergroup strata cut by hematitic breccia and diorite intrusions. Unconformably overlying Middle Proterozoic Pinguicula Group sedimentary rocks outcrop just east of the property. A diorite sill intrudes an inferred thrust fault in the centre of the claim block. Wernecke Breccia occurs peripheral to the diorite. In 1992, minor cobaltite was noted in a quartz vein near the northwest boundary of the claims, and tetrahedrite float assaying 3.3% copper and 408.0 g/t silver was found on the east side of the claim. Various specimens were assayed for gold but returned only trace.
Stream sediment sampling in 1994 returned several anomalous copper and gold values from the northwest and central drainages of the property.
