NEWSGoldcliff Discovers New Copper-Gold Targets at Copper Mountain

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Nov. 12, 2009) -George Sanders, President of Goldcliff Resource Corporation (TSX VENTURE:GCN), is pleased to report that several significant copper-gold targets have been established on the Tulameen Project claims. The target areas contain favourable geology, copper showings, anomalous copper-gold stream sediment values and defined airborne geophysical responses. Goldcliff's data interpretation of the Copper Mountain district provides a powerful exploration approach for new copper-gold discoveries in an established mining district. The Goldcliff claim position on the Tulameen Project involves 55 claims totalling 25,620 hectares. The large Tulameen land position is owned 100 per cent by Goldcliff.
The total historic production (to 1993) in the Copper Mountain camp is 1.7 billion pounds of copper, 8.4 million ounces of silver and 0.62 million ounces of gold. On the Copper Mountain project, Copper Mountain Mining Corporation reports a current resource (2009) of 5.2 billion pounds of copper. In October, Copper Mountain Mining Corporation and Mitsubishi Materials Corporation commenced construction of mining facilities for preparation of production in 2011.
Goldcliff's exploration model on the Tulameen Project incorporates both historic data and Goldcliff's exploration results. Goldcliff's claims contain similar geology to the Copper Mountain copper-gold deposits. The claim geology, combined with the anomalous stream sediment values and the positive airborne geophysical responses, have established several significant copper-gold targets for ground exploration. The geological setting of the Copper Mountain district's mineral deposits is complicated by faulting and folding. Goldcliff intends to use modern exploration technology to explore the claims at deeper levels for copper-gold deposits.
Goldcliff's exploration model recognizes that the porphyry copper-gold mineralization in the Copper Mountain district may contain supergene-higher-grade copper mineralization as a blanket over the primary copper-gold mineralization at depth. The Tertiary Princeton Group is the cover that would preserve the supergene copper mineralization from glaciation. The Tertiary Princeton Group overlies the Triassic Nicola Group where the Copper Mountain copper-gold deposits occur. The Copper Mountain deposits were de-capped by glaciation and the supergene copper was removed. The covered areas on Goldcliff's claims are the prime exploration targets.
In British Columbia, supergene copper blankets were mined at Craigmont (Merritt) and Afton (Kamloops). A new supergene blanket discovery by Serengeti Resources Inc. is at the Kwanika property, in north-central British Columbia, where the company reports (2009) a resource estimate of 1.6 million ounces gold and 1.1 billion pounds copper. In the southwestern United States porphyry copper region, supergene blankets are common over the primary copper orebodies because glaciation did not remove those blankets.
The Goldcliff claims have several surface copper-gold showings. Because of modern deeper-exploration techniques that facilitate the discovery of new mineral deposits at depth in established mining camps, Goldcliff's claims are well-positioned for copper-gold discoveries in the Copper Mountain district.
