Overview
The Goldcliff Copper Mountain-Tulameen project is a contiguous block of 56 mineral claims totalling 25,387 hectares. The claims were acquired by staking in early 2008 and are 100 per cent owned by Goldcliff. The project area has established infrastructure, with the town of Princeton, British Columbia as the centre of commercial activity. The project is situated west of Highway 3, a major transportation route in the province of British Columbia, and contains abundant access roads.
The Princeton Copper-Gold district is a world class copper-silver-gold mining region hosting porphyry style mineralization. The district hosts the Copper Mountain mine which operated from 1972 to 1996 and produced 1.74 billion pounds of copper, 9.1 million ounces of silver and 730,000 ounces of gold. Copper Mountain Mining Corporation is restarting the mine and is currently in the construction phase. The Copper Mountain mine project, located 15 kilometres southwest of Princeton, B.C. Current measured and indicated resources are 518.6 million tons of 0.31% Cu containing 3.2 billion pounds of copper with gold and silver credits. The project is 75 per cent owned by Copper Mountain Mining and 25 per cent owned by Mitsubishi Materials Corp.
A multi-sensor airborne geophysical survey, conducted in the fall of 2008, indicates that the intrusive suite hosting the Copper Mountain deposits extend to the southwest through the Goldcliff claim block. Recent mapping by B.C. Geological Survey confirms that the prospective geology extends onto Goldcliff's holdings. This geologic mapping, together with the historical data, provides strong evidence of structural settings that are similar to Copper mountain ore deposition. The airborne geophysical signatures also indicate conductivity and potassic alteration patterns consistent with porphyry style mineralization at Copper Mountain.
Field investigation and sampling by Goldcliff in the fall of 2010 have identified three target areas for copper and gold mineralization. The areas are named Whipsaw, Lamont and 15 Mile. The Whipsaw target contains three copper showings. The Lamont target contains five copper showings and one copper-gold showing. The 15 Mile target contains silica-carbonate alteration areas associated with strongly anomalous stream sediment gold and silver values.
The Copper Mountain-Tulameen project property is located within the southern portion of the Quesnel terrane, or Quesnellia, of the Intermontane tectonic belt of British Columbia. Quesnellia is a north-westerly trending belt of Upper Triassic to Lower Jurassic submarine and subaerial alkali and calc-alkali volcanic rocks, related sedimentary rocks, and comagmatic intrusive rocks.
In the southern part of the province this assemblage of volcanoplutonic arc rocks is known as the Nicola group. Throughout the Intermontane tectonic belt these rocks are noted for their mineral deposits, principally copper-gold porphyry deposits, and copper and gold skarns. The large, northerly trending fault systems -- such as the Allison, Summers Creek, Whipsaw and Boundary-- are believed to represent deep-seated crustal features that dominated the geology of the region in the Late Triassic time.
The Copper Mountain-Tulameen project property has the geological setting for alkalic copper-gold porphyry, Alaskan gold-platinum, Kuroko gold-silver-zinc, and other vein-type deposits associated with the Tertiary Princeton group and Triassic Nicola group rocks.
