Tam Property, British Columbia
OverviewThe Tam property consists of six contiguous mineral claims covering an area of 900 hectares. The claims are located approximately 21 kilometres northeast of Lac La Hache, B.C. The claims are accessible by good gravel roads from Lac La Hache. Central Resources Corp., has an option to earn a 100% interest in the property subject only to a 2% net smelter (NSR) royalty.The property is underlain by Nicola Group island arc volcaniclastic and sedimentary rocks of Upper Triassic age. These rocks are intruded by a number of Upper Triassic-Lower Jurassic plutons, stocks and dykes which are part of an alkaline intrusive complex underlying the Spout Lake area. Nicola Group rocks occur in contact with the Takomkane batholith to the east and north of the property. Basalt dikes and flows of Tertiary age crosscut and in part cover portions of the older rocks. The area was covered by thick sheets of ice during the last glaciation. This ice removed some of both the Tertiary and the older rocks and deposited till and glaciofluvial-lacustrine sedimentary cover of between one and 30 metres or more in thickness. The claims are located at the southeast end of a large arcuate aeromagnetic anomaly which reflects magnetite rich phases in the Spout Lake alkaline intrusive complex and/or alteration zones along its margin. Past exploration work along the southern limb of this anomaly located a number of occurrences mineralized with copper plus accessory values in gold, silver +/- molybdenum and tungsten. Mapping and trenching has identified propylitic to potassic altered augite - feldspar heterolithic andesite volcanic breccia and flow intruded by monzonites, monzodiorites and syenites. Heterolithic intrusive breccia occurs in proximity to intrusions. Widespread propylitic and locally potassic alteration occurs in outcrop accompanied by variable concentrations of pyrite, chalcopyrite, bornite mineralization and associated copper-gold-silver values. Exploration on the property between 1966 and 2008 has focused on the alkalic porphyry copper-(gold) potential with geochemical, geophysical, geological, percussion and diamond drilling programs identifying numerous prospects returning encouraging to potentially economic values. There are two significant copper (+/- gold) showings on the property; Tim 1 and Tim 2. The Tim 1 showing is located on the east side of the Tam 3 claim. The Tim 1 zone occurs near the contact between monzodiorite porphyry and propylitic Nicola volcanic breccia (Blann, 2001). Guided by the results of earlier geochemical and geophysical (IP and magnetometer) surveys and trenching, this zone was tested by Stallion Resources Ltd. (S.P.Butler, 1984) in 1983 with six short diamond drill holes totalling 312 metres. The more significant mineralized intersections are tabulated below. Significant Drill Intersections (1983):
Diamond drilling at the Tim 1 showing, by GWR Resources Inc., in 2001, returned the following results. Significant Drill Intersections (2001):
The Tim 2 showing is located on the northwest side of the Mat 3 claim. The highest reported assay values from sampling of the two trenches by Coranex Ltd. was from across 1.07 metres which returned 4.17% Cu, 0.019 opt Au and 0.91% Mo in the southern trench (G.C.Singhai, 1980). Grab samples taken over a strike distance of 44 metres by GWR Resources in 2001 returned 0.212 to 1.915% copper, 7 to 222 ppb gold and 5.9 to 64.5 ppm silver (Blann, 2001). Exploration on the property between 2004 and 2008 has included a 35 line kilometre, 3D induced polarization (IP) survey, a 39 line kilometre magnetic survey and a soil geochemical survey. The induced polarization survey has produced several anomalous resistivity and chargeability responses that can be interpreted as exploration targets that warrant further investigation. The combined 2004 and 2008 IP survey clearly shows that the IP anomaly in the central portion of the property extends to a depth greater than 350 metres below surface. None of the previous drilling in this area has penetrated beyond 100 metres depth. This is clearly a primary drill target. Magnetic surveys show two magnetic highs, one of which is partially coincident with gold and copper in soil anomalies. The magnetic and soil anomaly is partially coincident with an induced polarization (IP) chargeability high discovered in 2004 and 2008. Numerous untested copper soil anomalies with values in the 200 ppm to 2,000 ppm copper range situated on the southeast side, the northeast and the south central areas of the property warrant further investigation. Other areas of copper mineralization which have not been evaluated are reported in trenches and along road cuts on the Tam and Mat claims. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
