Point Location Description: Stripped area approximately 1.6 km west of Mishi Main Zone

Location Method: Based on Assessment

Access Description: Drive west along highway 17 from the junction of highway 17 and 101 for approximately 50 km to the Paint Lake Road (a gravel road heading south from highway 17). Drive south along the gravel road for approximately 50 km to where a west-trending bush road intersects the main road. Drive west approximately 1.5 km to the top of a hill. Walk approximately 1.6 km west along an overgrown bush road from the Mishi acces road to a stripped area on the north side of the road.

Geology Comments

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. The deformation and alteration styles of the western MDZ are similar to the central MDZ, however, the intensity of strain and alteration decreases further to the west as the Pukaskwa Batholith is approached.

Geologist: A Wilson

Notes: This showing is the westward extension of the Mishi Main zone. The original texture of the quartz-feldspar porphyry has been reduced to a quartz-carboante-sericite schist. This is the same rock unit that hosts the #2 and #4 ore lenses at the Main Zone.
