Jan 22, 2013 (S Fumerton) - The supracrustal rocks in the vicinity of the mineralization form a south facing homoclinal sequence with open flexural folds. This sequence has been disrupted by a number of major east - west shear zones which are commonly located within the ultramafic flows and associated with strong talc - chlorite - carbonate schists. These shears are also preferentially located along major lithological contacts which has resulted in tectonic slicing and repetition of the supracrustal sequence. In addition to the major shears there are a number of minor fault sets trending northeast and southeast. The mineralization is structurally controlled and hosted in a number of en-echelon arrays. The main arrays are hosted in mylonitic rocks within the east - west shears(110º), however, the individual mineralized zones within these arrays are centred upon oblique cross fractures trending 160 º or less commonly trending 020º. These cross fractures are parallel to the minor faults found in the area.

Dec 07, 2005 (A Wilson) - The deposit is located along the northern contct of a feldspar porphyry which has intruded a sequence of mafic and ultramafic metavolcanics. The ultramafics are peridotitic and pyroxenitic to basaltic komatiites. The basaltic komatiites are more common in the vicinity of the mineralization. The mafic metavolcanics are Fe tholeiites. They are fine to coarse grained, massive flows and pillowed flows intercalated with thin beds of mafic to intermediate tuffs. The main feldspar porphyry forms an elliptical intrusion with numerous irregular apophyses along the outer margins of the intrusion. This main intrusion is located on a shear zone and the apophyses along the northern contact in the vicinity of the mineralization may be intrusive in nature or fault slices and are associated with intrusive breccias.

Jan 22, 2013 (A Wilson) - Seven ore zones have been defined. The most important zones identified to date are the two Shaft Zones. The mineralization is located where cross fractures trending 135 - 150 degrees or less commonly 20 degrees intersect a mylonitic shear zones trending 110 degrees. Gold values in the Shaft Zones occur together with quartz-carbonate altered or silicified host rock, or with quartz veinlets. Where the host rock is porphyry, the better values are in pyritic, bleached and pale grey material. Red porphyry with specular hematite, magnetite and pyrite extends far beyond the main mineralization. Grab samples taken by the OGS in 1970 range from 3.00 g/t Au to 66.8 g/t Au. Grab samples collected from the hanging wall by the OGS in 1988 returned assays ranging from 0.3 g/t Au to 16.00 g/t Au. In a general sense, gold mineralization is associated with 1% to 3 % finely disseminated pyrite, which can locally attain concentrations of from 8% to 15%. Gold is also associated with 1% to 2 % fine grained specular hematite in altered, potassic, silicified feldspar porphyry. The grade appears to increase with an increasing amount of altered mafic/ultramafic metavolcanics provided the pyrite content has also increased.

Date: Oct 07, 1976
Geologist: W Karvinen
Notes: A brief visit was made to this property. The mine has been inactive since 1942 when a shaft was sunk and work was done on 3 level. All surface buildings and the headframe were burned by a bush fire in 1948. Gold occurs in disseminated pyrite in a pink porphyritic syenite which forms a lenticular concordant body, about 75 feet wide in a sequence of mafic tuffs and flows. Quartz veining is not abundant however brecciation along contacts appear to be well mineralized. No significant carbonatized rocks are present. An open shaft and raise are covered by steel railings.

Date: Jun 16, 1991
Geologist: D Farrow
Notes: In company with Lorne Luhta, Resident Geologist and K Lapierre mine geologist a tour was made of the recent stripping. On going stripping has exposed an area approximately 20 x 90m over the 'A' and 'A South' zones, and another area 25 x 250m over north and south shaft zones previously called the 'B' zone. The second stripped area joins an area stripped by Sulpetro. At the time of the visit two or three more days of stripping were planned to uncover the west vein about 150m west of the shaft. Channel sampling was also planned for the future. Detailed examination of the 'A' zones has revealed a complicated geological scenario whereas the shaft zones appeared somewhat less complex. Major considerations such as camp establishment and logistics, power supply, tailings disposition and underground development are still in the planning stage. Tentative plans, however, include the use of a decline by-pass to access the ore intersected by the present decline ramp system. Parallel Lake is under consideration for tailings disposal, with Twin Lake the eventual destination of decanted water. [ PRECIS ]

Geologist: S Fumerton
Notes: Met on site by the watchman, M. Yvon Cloutier who make daily visits to the site from Foleyet. The shaft has been decommissioned with the cage and hoisting rope removed, also the portal has been boarded up. In addition, various pieces of unassembled mill equipment together with tanks cut up with a torch from the Emerald Lake Mine has been stockpiled on site. Finally, diamond drill core from a recent drill program has been stacked in cribs which are now starting to lean over.
