Exploration and Mining History

1961-62: M.J. Boylen conducted detailed geology, mag, EM, Airborne E.M. and magniphase surveys and diamond drilling (12 holes). Four shallow trenches blasted uncovering sulphide mineralization. - Seeber claim group- Four trenches, 5 ddh (1090 feet). Morrison-Eden Group- Six ddh (2319 feet). Ouilette-Eden Group - One DDH (835 feet). 1972: detailed Mag and EM south of Auger Lake by Imperial Oil Enterprises. 1976: New Jersey Zinc Exploration Co. completed 9 DDH (1053 feet) on Ryley-Cormac Occurrence. 1986: Airborne MAG, EM and VLF by Aerodat for Gold Fields covering Ryley-Cormac Occurrence. 1987: Gold Fields drilled one 807 foot DDH northeast of original Boylen Occurrence. 1989: Prospecting, trenching and recon MAG and VLF-EM over Boylen occ. and Kawitos Lk. area. 1990: Falconbridge optioned 17 claims and staked 176 claims followed by linecutting, mapping, lithgeochemical survey, HLEM and MAG surveys and power stripping. 1991: Further linecutting by Falconbridge, geological grid mapping, 1723.5 m of diamond drilling. 1993: Noranda Exploration Company Ltd. bought 25% interest in the property. 1995: Noranda completed further MAG, Max-Min, recon and detailed mapping and airborne geophysics, and drilled 3 DDH totalling 692 m. 2010: Pro Minerals Inc. conducted borehole and surface pulse electromagnetic surveys.

Mineralization Comments

03/31/2021 (T Pettigrew) - Drill holes PO-5 and PO-6 tested two sets of northeast striking en-echelon HLEM conductors to the Southwest of the Ryley Cormac showing (MDI52P08NW00006). The conductors are offset roughly 150 metres in a northwest-southeast direction. The western limit of the southernmost conductor has incomplete HLEM coverage. Hole PO-5 intersected a zone of disseminated to partially remobilized massive sulphides from 152.77 metres to 154.08 metres (grading 1.13% Cu and 83.1 g/t Ag over 1.31 metres) and a thick chlorite-garnet alteration zone from 55.19 metres to 152.70 metres. The best assay from this hole returned 2.43% Cu, 0.08% Zn, 173 g/t Ag, and 0.07 g/t Au over 0.39 m. Hole PO-6 intersected a zone of thinly interlayered sulphide bands from 33.66 metres to 35.83 metres (grading 1.17% Cu and 12.8 g/t Ag over 2.17 metres), and a zone of partially remobilized semi-massive to massive sulphides from 116.60 metres to 117.87 metres (grading 2.09% Cu, 32.37 g/t Ag, and 2.00 g/t Au over 1.27 metres). The best assays from this hole returned 2.42% Cu, 0.11% Zn, 24 g/t Ag and 0.55 g/t Au over 0.66 m and 2.84% Cu, 0.02% Zn, 33 g/t Ag, and 2.81 g/t Au over 0.87 m. Biotitic units (metamorphosed mafic muds) and sporadic zones of moderately strong chlorite-garnet alteration were also intersected (Assessment report 52P08NE0001). Multiple surface samples were also taken by Shaun Parent in the area with anomalous results, but those assays were not provided.
