Point Location Description: precise
Location Method: AMIS Site Visit
Access Description: The site is located 6.5 kilometers, southwest of the town of Goudreau (which lies along the ACR railway). A bush road is taken using an ATV (as the road is blocked at Goudreau) directly to the site. The power line from Goudreau can also be followed to the site.

Dec 07, 2005 (A Wilson) - The Murphy Gold Mine is hosted by the western domain of the Goudreau Lake Deformation Zone (GLDZ). The GLDZ is up to 4.5 km in width and strikes roughly 100 degrees for at least 30 km. It is coincident with the major contact between cycle 2 (2720 Ma) felsic to intermediate pyroclastic metavolcanic rocks to the south, and cycle 3 (2700 Ma) massive and pillowed mafic metavolcanic rocks to the north. The western domain of the GLDZ is composed of 85 - 115 degree striking brittle and brittle-ductile high-strain zones displaying dextral oblique-slip displacement. Lineations plunge moderately to steeply to the west.

Nov 02, 2010 (A Wilson) - The quartz-carbonate vein cuts across hornfelsed intermediate to mafic pillowed and massive metavolcanic rocks and associated quartz-feldspar porphyry intrusions. The western part of the vein is bordered by fine-grained, leucocratic quartz-mica schists which grade outward into gneissic trondhjemite. The eastern end is bordered by chlorite-quartz-calcite-muscovite schists. The porphyry is considered to be an apophyse of the Gutcher Lake Stock.

Dec 07, 2005 (A Wilson) - The vein quartz is of two separate ages and the metallic minerals are associated with the second order quartz. Pyrite, pyrrhotite, chalcopyrite, sphalerite, bornite and gold are the dominant metallic minerals associated with the vein. Gold is found in cracks in the quartz and carbonate (ankerite) within the vein. The best assay from a sample taken from trenches by an OGS field party was 0.04 oz/t over 10 feet. A grab sample taken in 1990 returned a value of 0.17 oz/t from a massive quartz vein. Well defined quartz carbonate veins are much less prevalent than zones of intensely sheared and brecciated rock which have been subjected to quartz flooding. The best assays from the 1986 drilling of Mascot returned values of 2.416 oz/t Au over 3.28 ft.
Nov 02, 2010 (A Wilson) - Fe-carbonte lateration is found in both the mafic metavolcanic rocks and the felsic porphyry dikes found adjacent to the Murphy vein system. The alteration is localized in highly strained mafic metavolcanic rocks, decreases away from the main veins system to a chlorite calcite assemblage in the less deformed rocks.
