Berg Copper-Molybdenum-Silver Deposit
Terrane Metals' second significant asset is the Berg Project located in west-central British Columbia, Canada, some 84 km southwest of Houston, BC and 22 km northwest of Imperial Metals' Huckleberry Mine. From 1965 to 1980, Kennecott Exploration Ltd and Placer Dome Inc completed 119 diamond drill holes totaling 20,128 metres on the property and developed a significant copper / molybdenum resource. The Joint Venture partners also completed numerous metallurgical tests, environmental studies, and financial analysis on the Berg Project. Development plans envisaged an open pit mining operation. The Project was shelved in the early 1990's due to declining metal prices and the two Joint Venture partners shifting their attention to other parts of the world.
In 2006, Terrane Metals obtained 100% ownership of the Berg Project and reactivated the property to evaluate the potential of bringing the Project to commercial production. Key highlights include:
Key Highlights:
- July 2006 -- Terrane acquires Placer Dome's share of the Berg JV
- September 2006 -- Terrane acquires Kennecott's share of JV to become 100% owner of the Berg Project
- May 2007 -- Initiated Environmental Baseline Study as well as Public and First Nations consultation programs
- May-October 2007 -- Completed 11,289 metres of diamond drilling in 29 core holes aiming to verify and expand the historic resource
- December 2007 -- Created new 3-D geological model; Completed preliminary metallurgical test-work
- April 2008 -- Announced First NI 43-101 Compliant Resource Estimate with contained metals of 2.5 Billion lbs Copper, 299 Million lbs Molybdenum, 25 Million ozs Silver

Note:
(1) Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability.
(2) Copper equivalent grades are calculated using four-year rolling average metal prices of US$2.43/lb Cu, US$27.43/lb Mo, US$10.23/oz Ag and take into account forecast metallurgical recoveries into separate copper and molybdenum concentrates.
