Dec 07, 2005 (A Wilson) - The mineralized quartz veins are associated with zones of foliation and shearing that transect the generally massive granitic rocks. Primary orientation of quartz veins is approximately 330 deg, dipping steeply to the west. Quartz filled extension fractures have an almost perpendicular orientation at approximately 220 degrees.

Dec 07, 2005 (A Wilson) - The mineralization is hosted in a leucocratic tonalite with roughly equal amounts of quartz and plagioclase. Biotite is the main mafic mineral with minor amounts of clinopyroxene. Magnetite and chlorite occur in minor amounts as an in situ alteration product of biotite. Chlorite also occurs as fracture and vein fillings. Sericite alteration of the plagioclase is much more widespread. Near the mineralized zone, the rock is marked by a grain size reduction, abundant sericite and carbonate in the rock matrix. Trace amounts of hematite occur in these sheared tonalites. The host rock consists of quartz diorite to granodiorite which are typical phases in the Chester Granitoid complex. The more felsic phases occur as small intrusive bodies cutting the mafic phase. A well mineralized quartz vein occurs between a porphyritic granodiorite in the hanging wall and a diorite in the foot wall. Along the hanging wall contact, a strong schistosity and fracturing is developed.

Dec 07, 2005 (A Wilson) - The 325 ton bulk sample taken in 1979 had a grade of 6.03 g/t Au. A 295 tonne bulk sample collected in 1982 returned an assay of 5.8 g/t Au. The best assay returned from the 1987 diamond drill program was 1.1 g/t Au over 0.7 m. A grab sample collected by the OGS in 1993 returned a value of 0.03 g/t Au and 0.1 g/t Ag.

Notes: A number of striped outcrops lie in the viciniyt of the #6 vein. It was one of these outcrops that was examined at the time of the visit. This outcrop is located near the north end of the stripped area and is readily accessible by boat off the small river joining the Upper and Middle Three Duck Lakes. Outcrop consists of medium to coarse-grained gabbroic rock intruded by a medium to coarse-grained dioritic intrusive. Quartz veins, 2-4 cm, are associated with diorte intrusive generally concordant. Quartz filled tension fractures are commonly seen associated with the quartz veining as well as are small mm scale tourmaline crystals within the quartz. Scattered pyrite was observed along margins of quartz veins and within dioritic wall rock. Quartz veins are commonly seen as being rusty at various locations along surface, but taking a good sample was difficult. The primary orientation of the quartz veins are in the NW direction (330) dipping steeply to the west. Quartz filled tension gashes have an almost perpendicular orientation at approximately 220 degrees.
