Point Location Description: Outcropping of quartz vein on north side of a hill.
Location Method: Based on Assessment
Access Description: Access to general area of the occurrence is easy via the Dore Main Haul Road and the Orofino Mine / Rundle Mine access road. Access to the prospect is more arduous and can be accomplished by canoe up the Swayze River from where the road intersects the Swayze River for about 3km, negotiating a set of rapids and one set of falls.
1936: Hollinger Mines had a number of prospecting parties working in the area and the Rundle-Frederickson showing is known to have been found by 1939. Early work is known to have consisted of stripping and trenching with several holes being drilled in the immediate area. 1978: Hollinger is known to have drilled five additional holes in the area to the east around what is known as the Miquelon #2 vein. One hole intersected a zone with pyritic quartz returning values up to 1.11 opt over 1 foot. 1982: Sulpetro Minerals optioned the property which included the Frederickson-Rundle and Rundle-Hanna showings. Sulpetro recompiled all of Hollinger's work and mapped the property. Additional anomalous zones besides the Miquelon #2 vein and other discoveries made by Mr Rundle were found during this work.

Dec 07, 2005 (K Houle) - Vein is exposed for about 100' (30.5m) on surface, is flat lying and dips shallowly to the southeast.

Dec 07, 2005 (K Houle) - According to the 1950 description by N. Hogg, the Rundle-Frederickson vein is 'a wide, flat dipping quartz vein which has resisted weathering, and forms a small outcropping on the north side of the hill'. The vein is described as being milky white with streaks and bands of light grey rock resembling aplite. Wall rock is described as a medium grained diorite.

Dec 07, 2005 (K Houle) - The vein on surface is described as being poorly mineralized with disseminated pyrite being more abundant in inclusions and streaks of wall rock.
Dec 07, 2005 (A Wilson) - The best assay obtained by the OGS in 1993 was 0.04 g/t Au from a grab sample of quartz vein material. The earliest reported assay (1939) was $0.40 Au over 6 inches'.

Notes: Outcrop on north facing hillside of quartz veining believed to be Rundle-Frederickson showing. Outcrop is overgrown in comparison to 1950 photograph that accompanies the assessment file and has been trenched in a N/S direction at three locations. The approximate dimensions of the outcropping was found to be about 25x10m elongated in the E/W direction. The outcrop consists predominantly of grey to white massive quartz with streaks of grey silicified rock. Mineralisation is present in several forms including fine disseminates, thin stringers and semi massive blebs of pyrite. Iron oxide staining is a common alteration along fracture surfaces. The dioritic wall rock as indicated on old geology maps was not observed although numerous large granitic and dioritic boulders have been seen in the immediate area. Another trench was located about 100m to the west (UTM 17 391387 5307502) on the east slope of a small hill. Two sample were taken at this location, the first is of quart veining with weak carbonate alteration, the second is of the dark black weakly foliated wall rock. This trench has poor exposure as it is mostly filled with overburden now and has numerous mid size trees growing out of it.
