Point Location Description: Stripped outcrop on south side of hill
Location Method: Field Visit with GPS
Access Description: Access to the general area of the occurrence is easy via the Dore main haul road and the Orofino Mine/Rundle Mine access road. Several kilometers south of the Swayze River, a good drill road branches off of the Rundle road and goes south before turning west and running to Newton Creek. At Newton Creek, the road becomes a winter drill trail extending south and east to the mineral occurrence in a stripped outcrop.

Mar 28, 2011 (A Wilson) - The shearing and foliation parallel to the porphyry dike contacts does not extend any distance from the porphyry dikes. However, the quartz vein stockwork in the porphyries are parallel to different joint sets which extend some distance from the stripped area. The rectangular veins are oriented 180/80W, 280/65N (parallel to the contact). The late en-echelon veins are oriented 155/80W.

Dec 05, 2011 (A Wilson) - The stripped area has exposed a series of quartz porphyry dikes intruding a pillowed basalt. In the area exposed, this basalt is strongly altered to iron carbonate and chlorite and is sheared adjacent to the porphyry contacts. Otherwise, the porphyry is strongly foliated. Away from the stripped area, the basaltic rocks form massive coarse and fine-grained or variolitic flows with no significant alteration. There are two types of quartz porphyry dikes; an early phase of quartz porphyry which is a pink colour, massive, with trace amounts of pyrite. These early dikes are 2 - 5 m thick and trend 280. Only one of the second phase of porphyry dikes have been exposed and has intruded along the axis of an early phase porphyry. This dike is about 5 m thick, white and is marked by an absence or weak carbonate alteration, and minor amounts of pyrite. Both dikes have an aphanitic matrix and contain 10-20% quartz phenocrysts. Both phases of porphyry are pervaded by an extensive stockwork of thin quartz veinlets (<5mm). These veins also occur in two stages. The earlier veins form an extensive rectangular pattern of veins every 5 - 50 mm. In the white propphyry, these veins are almost exclusively formed of quartz, but in the pink porphyry the veins are composed of chlorite and quartz. The later veinlets are composed of quartz and carbonate, occur in widespread en-echelon arrays in both porphyries and locally are associated with some shear breccia. Drilling to date has indicated numerous extensive shear vein systems that are open along strike and at depth. Mineralization is hosted in local brittle shears in crystal tuff, altered basalts and porphyry dikes within carbonatized, silicified and pyritized shear envelopes

Dec 05, 2011 (A Wilson) - Chip samples taken by the OGS in 1992 returned values of 0.27 g/t Au, 6.2 g/t Au, 0.14 g/t Au and 0.30 g/t Au. The best assay reported by Dome Exploration was 6.00 g/t Au. Best intersections from the 2002 drilling returned values of 8.18g/t Au over 5.05 m. Significant assays from the Red Pine drilling include: 4.05 g/t Au over 35 m including 7.76 g/t Au over 15.42 m in RPX10-2 and 2.65 g/t Au over 40 m in RPX-10-08. Resampling of Greenshield historic drill core yielded the following results 2.35 g/t Au over 52.4m, including 5.07 g/t Au over 3.0 m and 5.45 g/t Au over 17.00 m in G02-01 and 1.44 g/t Au over 20 m in G-02-02.

Geologist: B Atkinson
Notes: The Michelle gold occurrence is overlain by 1 to 2 m of glacial deposits, which had been recently excavated to expose the bedrock. An east-trending 0.5 m wide albitite dike occurs at the contact between iron-carbonate-altered and deformed mafic flows and feldspar porphyry intrusions. At the west end of the trench, a fault breccia contains large rotated blocks of porphyry, aplite and contorted mafic volcanic rocks. Variolitic mafic flows outcrop on the west end of the trenched area. Roadside outcrops 3 km east of the Michelle occurrence (UTM Zone 17, NAD 83, 398132E, 5304613N) have been stripped, sampled and mapped by Red Pine. Referred to as the DZ3 Zone, the rocks are mylonitized mafic flows cut by foliation-parallel mafic dikes and boudinaged quartz veins. Several episodes of deformation have affected the rocks and the transposed foliations trend 090/65N.
