McKinney Gold Mines Ltd under the Ontario operating subsidiary of Jogran Mines Ltd. discovered copper and molybdenum in a porphyry intrusion while drilling EM anomalies in 1964. This included a 6 hole diamond drill program. In 1964, a follow-up diamond drill program was conducted by Jogran Mines Ltd. that expanded the drilling to 9 holes totalling 5437 feet following the intersections of copper mineralization within the quartz-feldspar porphyry a In 1966, Phelps-Deodge Corp. of Canada Ltd. drilled a series of drill holes and intersected copper mineralization. In 1981, Roy Rupert, Consulting Geologist, re-assayed 3 holes. Two holes were by Jogran Mines Ltd. and one hole was by Phelp's Dodge Corp. This was undertaken to confirm previous analysis and to determine the quantities of precious metals or tungsten that mayber present. Confirmation of analysis was considered important because of changes in the state of the art of low grade molybdenum analysis since 1964. In 1991, Noranda Exploration Company Ltd., re-assayed 8 holes drilled by Jogran Mines Ltd. These holes included J-13 to J-20. Between 2006-2010 RRS Syndicate have completed a strippind and trenching program within the area along with a 3 hole diamond drill program.

Geological Age: Archean
Mar 30, 2011 (A Pace) - The porphyry is situated within the Archean metavolcanics of the Batchawana Greenstone Belt where is is bounded from the north and south by granite and granodiorite. The metavolcanics consist largely of massive and pillowed basic intermediate flows. The porphyry is fine grained with phenocrysts of quartz and feldspar. Quartz appears as rounded quartz-eyes and at times the fine-grained matrix is cut by quartz stringers.

Mar 30, 2011 (A Pace) - The porphyry body has a minimum area of 600 by 400 feet and extends to a minumum depthe of 680 feet. Mineralization is quite uniform throughout drill cores. Nine holes which have been drilled in the porphyry area by Jogran Mines Ltd. can only be considered as "indicators" of grade of mineralization and are of a preliminary nature in outlining the dimension and extent of mineralization in the porphyry. The nine holes are grouped into three(3) cross-sections at right angles to the structural features (faults and drag-shears) of the mineralized mass (porphyry and volcanics) (1) Northern Section Holes No. 14, 19, 21. Lineal footage of sampled and assayed core which might be part of and within an open-pit dimension amounts to 1070 feet and averages 0.170% copper and 0.052% MoS2. (2)Center Section, Holes No. 13, 15, 20, 21. Lineal footage of sampled and assayed core which might be part of and within an open-pit dimension amounts to 1, 584 feet with an average of 0.204% Copper and and 0.057% MoS2. (3) southern SEction Holes 16, 17, 18. Lineal footage of sampled and assayed core which might be part of and within an open-pit dimension amounts to 912 feet and averages 0.204% Copper and 0.047% MoS2. The over-all average grade of mineralization based on the lineal footage of sampled and assayed core of the nine (9) holes and that part of the mass which might be within an open-pit dimension becomes 3, 566 lineal feet averaging 0.1935% Copper and 0.0528% MoS2. In 1981, Roy Rupert assayed one high 13.44g/tonne gold assay that was obtained from previoulsy unsplit calcite fissure-filling vein in hole J-14 of Jogran Mines Ltd. This may warrant further investigation.

Notes: The Jogran porphyry is dted as a Keweenawan aged stock intruding the ARchean metavolcanic rocks. The porphyry consists of a fine grained matrix with phenocrysts of quartz and feldspar. The Jogran porphyry carries disseminated chalcopyrite and molybdenite and specular hematite mineralization. In some instances the porphyry illustrates quartz veining cutting the fine grained matrix. Mineralization was also noted along the margins of the porphyry where these margins represent a fracture envelope as a result of intrusive forces furing the porphyry where these margins represent a fracture envelope as a result of intrusive forces during the porphyry emplacement. Mineralization observed along the fracture envelope surrounding the Jogran porphyry consists of chalcocite, chalcopyrite and malachite. Grab sample colleted and assayed fromt eh Jogran Porphyry assayed 1.4% Cu.
