OGK Property
The OGK property is a large claim block located in the Omineca Mining Division of north central British Columbia, Canada, approximately 300 kilometers northwest of the City of Prince George. The property is within NTS map sheets 094C and 093N, centered at Latitude 56 2’ 20” N and Longitude 125° 33’ 00” W; or UTM Zone 10, 341,000 East and 6,213,500 North (Figure 1). The property lies along Osilinka River and its tributary Haha Creek west of Cat Mountain and East of Omineca River.
Initial exploration in the area was in the times of the placer gold discoveries in the Omineca Area (Parsnip and Finlay Rivers (1861); Vital |Creek (1869) (Manson Creek, Germansen Landing (1870-71). The Lorraine copper-gold porphyry to the south was staked about 1930 and first explored by Cominco 1943-47 and then by Kennecott after restaking in 1947. The drilling of the Lorraine property led to scattered exploration throughout the area in the late 1960’s, but access at that time was poor. Gold is said to have been discovered in-situ on the summit area of Cat Mountain in the 1940s. Significant exploration at Cat Mountain, east of the Tajiri property dates to 1957 when Croyden Mines completed trenching and two short drill holes on magnetite lodes exposed on the summit area of Cat Mountain. BP Minerals Ltd. staked the Cat Mountain property in 1975 and delineated a large copper anomaly covering the entire summit area, completed ground magnetic surveys and 6 km of IP work. From 1969 – 1975, Union Miniere Explorations and Mining Corporation Limited (UMEX) conducted programs of geological mapping, soil and rock sampling, IP and magnetic geophysical surveys, trenching and diamond drilling (25 holes, 3629m) on the Boundary, Midway, Cirque and Fault targets situated to the south and east of Tajiri’s claims . This work resulted in the definition of inferred (possible) reserves (pre 43-101) for the Boundary deposit of 7.2 million tonnes grading 0.55 percent copper and 4.11 grams per tonne silver (Dyson, 1974). The best drill hole from the Boundary deposit is 0.68% Cu over 179.8m in hole 74-6 from 3.7- 183.5m including 1.59% Cu over 39.6m from 3.7-43.3m. Within what is now the Tajiri claims, two showings known as Flame and Goat were explored in the 1970’s. The Flame was held by L.M Hart and optioned to Thor Explorations Ltd. Immediately adjacent to one of the Tajiri claims, drilling by Teck Corp. in 2006-07 intersected significant copper values in what is known as the Slide showing. The best of these drill holes, JTM-06-07, intersected 55 meters grading 0.72% Copper with anomalous Gold values. This area is interpreted by the Company, to represent the peripheries of an alkalic Duckling Creek type porphyry system that will form the focus of future exploration efforts on the Property.
GEOLOGY AND MINERALIZATION
Three distinct styles of mineralization are currently recognized at the OGK Project. At the Slide Zone, disseminated copper mineralization (chalcopyrite) is noted within monzonite of DCSC in conjunction with strong potassic alteration. Also in this area, quartz-sulfide veins bearing chalcopyrite and pyrite are seen with proximal disseminated sulphides. Gold values up to 2.99 g/t Au were sampled from a vein at the edge of a north-trending shear zone at the Slide. In the Nova Zone (northwest project area) large quartz veins, traceable for up to 40 m, are found bearing minor sulphides including pyrite, chalcopyrite and galena are found. Several high gold assays were obtained in samples from these veins.
DEPOSIT STYLES
The OGK property has a high potential to host an alkalic porphyry style copper-gold deposit and this has been the main target of recent exploration. All known deposits of this type in British Columbia are found within Quesnel and related Stikine Terrains which form a 1200-kilometre-long belt of volcanic and sedimentary rocks that stretch from the U.S. to nearly the Yukon border across the centre of British Columbia. These deposits form within and proximal to intrusions that are generally characterized by large magnetic and potassium alteration signatures. Alkalic Porphyry deposits typically host relatively high concentrations of copper and gold with accessory silver, molybdenum, palladium and platinum. Many alkalic porphyry districts are characterized by multiple deposits and display strong structural controls. Several deposits may occur within an area of a few kilometres and may range in size from less than 10 to over 300 million tonnes. Several examples of this deposit type are the Galore Creek, Mt. Milligan and Mt. Polley copper-gold deposits. In close proximity to the OGK Project is the Lorraine Copper Deposit which is hosted in DCSC rocks similar to those found on the OGK Property. In 2012 Teck Resources Ltd. and Lorraine Copper Corp. issued a 43-101 compliant indicated resource containing 86,339 million pounds of copper and 47,000 ounces of gold (using a 0.2% Cu cut-off) at the Lorraine deposit. Additionally, vein-hosted gold is found in the northwest of the property and suggests the potential for discovery of epithermal style gold.
