Point Location Description: Diamond drill holes
Location Method: Conversion from MDI
Access Description: The Michon Copper Showing lies midway between the East Jackpine River and the Jackpine River. It is situated along Glacier Creek about 5.6 km southeast of Cosgrave Lake (claim map G 25, Cosgrave Lake area). The copper showings occur along the Glacier Creek Fault from the Potter occurrence in the south to the Michon occurrence in the north. Access is by the Little Bear Quarry Road (Camp 81 Road) which is located about 19 km east of Nipigon. The showing occurs about 25.6 km northeast along this road.
1955: Staked by Reino O. Kotanen, John W. Price and P. Forsgren. Copper mineralization was discovered along the Glacier Creek Fault 1956: Thirteen diamond drill holes totalling 1061 m were drilled by Ray Potter and Associates. Optioned to Frobisher Limited who conducted geological, magnetometer and electromagnetic surveys over the area. Seven diamond drill holes totalling 583.6 m were drilled by MacLeod Cockshutt Gold Mines Limited. 1961: The claims lapse. 1961-1965: Claims were restaked but no work was recorded. 1965: R. Barker drilled 10 holes totalling 1445 feet. This work was done on the Miron property (Area E). 1966: Big Nell Mines Ltd. conducted a compilation and property report by T.W. Page. 1967: A small amount (unknown total) of diamond drilling was completed by Midland Nickel Corp. Ltd. 1969: Geophysical (EM) survey was conducted by Oja Limited. Canadian Addicks Mining Corp. conducted stripping, trenching and sampling over four main zones. 1971-1972: Six drill holes totalling 811 feet were drilled. The Miron or Area E was covered. 1976: J. Haggerty staked the prospect and all interest was transferred to Vantage Mining Company Inc. 1977: Geological, geophysical (EM) surveys were conducted and reports submitted by E.A. Hart Limited and R. Kidd, respectively. Seven diamond drill holes, aggregating 697.9 m were completed on TB 407860. 1981-1982: The claims lapsed. 1983: B. Michon staked the Dello Lake occurrence as well as the north end of the copper occurrences known as the Michon copper occurrence. 1988-1989: The Glacier Creek property (Potter and Miron) was staked by D. Kukkee who conducted prospecting, sampling, striping, trenching. A 60 claim block was staked. 1990: D. Kukkee with help from an OPAP grant conducted stripping, trenching, prospecting and sampling. A VLF survey was conducted. 1990-91: Noranda optioned the property and conducted geological mapping and diamond drilling.

Dec 07, 2005 (B Nelson) - Schnieders and Smyk (1990) described the general geology: The area is underlain by granite gneiss and metasedimentary rocks, as well as later granitic stocks and dikes. The metasedimentary rocks include biotite quartz feldspar gneiss, garnet gneiss, hornblende schist and augen gneiss as identified by Pye (1965). The metasedimentary rocks identified by the authors were predominately biotite schists, and biotite quartz feldspar gneiss and displayed strong foliation and evidence of folding, faulting and shearing. Granite and granitic migmatite envelop the metasedimentary xenoliths and remnants. Schnieders and Smyk (1990) also briefly described the Michon occurrence as 'at another location, a crack seal vein system has abundant chlorite slips and seams. The vein reaches a maximum width of 0.80 m. Vein breccia is common consisting of quartz rich fragments and granitic fragments in a more mafic matrix'. This area is shown as Area E in the Marchand (1990) report. Oja (1969) and Marchand (1990) also suggested that the intersection of the northwest trending faults with the northeast trending Jackpine River Glacier Creek fault may be significant to gold and copper mineralization. The author suggests a left lateral or sinistral displacement on the Glacier Creek Fault and Marchand (1990) also shows a left lateral or sinistral displacement for the east Jackpine River fault.

Dec 07, 2005 (B Nelson) - In 1989 more than 23 grab and chip samples (89 BDK 01 to 23) were collected by the Resident Geologist from an area over 2 km in strike length and covering Areas A to E (Marchand 1990). Samples from the Michon occurrence, (North Showing or Area E) assayed up to 0.042 ounce per ton Au and up to 6.7% Cu. Assays of grab samples collected in 1988 by D. Kukkee returned up to 11.12% Cu, 0.233 ounce per ton Ag and 0.135 ounce per ton Au. Selected grab samples (21305, 21308, 21309) collected by Noranda Exploration staff in 1983 from the Michon Copper showing (North Showing) on Claim TB 745660 assayed as high as 0.04 ounce per ton Au, 4.62 ounces per ton Ag and 23.1% Cu.
Date: Feb 28, 1997
Geologist: B Nelson
Notes: Resident Geologist personnel visited the occurrence June 28, 1989, and June 28, 1990. Sampling by Resident Geologist personnel in 1988, 89 and 90 returned values of <0.01 to 0.05 oz/ton Au, nil to <0.10 oz/ton Ag and 3500ppm to 7.15% Cu. It is, however, unknown where along the fault these samples were taken.
