NTS Grid: 41O16NW
Point Location Description: Large stripped and trenched outcrops to south of clearing on logging road
Location Method: Field Visit with GPS
Access Description: Access to the area of the occurrence is easy via the Dore Main haul road and the Orofino Mine/Rundle Mine access road. South of the Orofino Mine site, there ae a series of drill roads branching off to the south-southwest. One of these trails approaches the lake from the south then follows the shoreline westward to an outflowing creek near the occurrence. Alternate access is by way of the Foleyet timber road that leads south through the Swayze greenstone belt from the junction with Hwy 101, 10 km east of Foleyet. At a point 28 miles south on the Foleyet timber road, a branch road leads southeast into the property.

Mar 28, 2011 (A Wilson) - Highly foliated to sheared over the extent of the exposure. Foliation is as approximately 248/85N.

Dec 05, 2011 (A Wilson) - The stripped outcrop exposes highly foliated to sheared intermediate to mafic rocks with a partial exposure of the felsic dike to the south. Rock is highly altered to Fe carbonate and contains numerous small subparallel and cross-cutting quartz veins <1cm. Overall, the unit appears weakly sericitic. Sections of the outcrop appear tuffaceous with 1 - 3 mm flattened fragments and some evidence of banding. the unite exhibits strong orange/brown weathering and a medium to light grey fresh surface. The volcanic unit is in contact with quartz-feldspar porphyry dike to the south. Sharp, sheared contact with about 1 m of exposure. The porphyry is a light pink colour and altered/bleached proximal to contact with the volcanic unit. Red Pine has defined a laterally extensive vein shear system hosted within feldspar porphyry and mafic volcanic protoliths. The system extends for more than 1 km in an east/west orientation. Geological surface mapping has identified at least one other parallel structure of similar characteristics indicating that the shear structure likely consists of a number of stacked contacts.

Dec 05, 2011 (A Wilson) - Grab samples taken by the OGS in 1993 returned values of 1.08 g/t Au and 0.7 g/t Au. Grab samples collected by Dome in 1982 returned values as high as 6 g/t Au. Sulphide mineralization consists of fine disseminated pyrite and blebs of pyrite occurring along margins of small quartz veinlets and along foliation plans. Greenshields drill hole G04-16 returned values of 4.24 g/t Au over 3.65 m from this zone. Assays from the 2010 drilling by Red Pine returned assays of 1.58 g/t Au over 6.88 m in RPX-10-09, 1.27 g/t Au over 9 m and 1.52 g/t Au over 4.74 in RPX-10-10 and 1.53 g/t Au over 1 m in RPX-10-11.

Notes: The central part of Newton Township is underlain by pillowed mafic metavolcanic flows of the October Lake Formation. The Newton High Strain Zone structurally overprints the rocks and the Dale anticline trends westward through the area (Heather and Shore 1999). At the Krista occurrence, intensely deformed mafic metavolcanic flows are cut by quartz-feldspar porphyry dikes that are themselves distorted, disrupted and boudinaged. A large boudin of grey aphanitic albitite carrying 3% fine pyrite outcrops at the crest of a small hill on the Krista occurrence. The mafic flows are intensely altered to iron carbonate and chlorite. 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.
