Belt: Mishibishu Lake
Geological Age: Archean
Dec 07, 2005 (A Wilson) - All of the mineralized zones occur in the most highly strained portion of the Mishibishu Deformation Zone. The tectonic-stratigrapy strikes at 115 and dips at 45 degrees north. The Magnacon mineralized zone has a chlorite dominated structural hanging wall and a sericite dominated structural footwall. The Mishibishu Deformation zone is the largest of the deformation zones in the belt, measuring approximately 40 km in length and several hundred metres up to 1.5 km in width. The zone is located north of the Mishibishu Lake Stock and lies along the lithological contact of mafic metavolcanic rocks to the north (hanging wall) with clastic metasediments to the south (footwall) The Western MDZ is that portion of the deformation zone west of Macassa Creek.

Dec 07, 2005 (A Wilson) - The samples appear to have been taken close to the sheared contact between the Mishibishu Lake Stock and the metavolcanic-metasedimentary units. The sample may have been taken from a quartz vein or at the contact with a diabase dike.
Dec 07, 2005 (A Wilson) - A series of grab samples collected in 1983 returned gold values as high as 6.95 oz/t Au.
