Mining Companies - Metals Companies
Revett Minerals is an established Silver-Copper Producer that owns and operates the producing Troy Mine and the world-class development stage Rock Creek project (containing an estimated 229 million ounces of silver and 2 billion pounds of copper); both properties are located in northwestern Montana. The Company is listed on the Toronto Exchange under the symbol (RVM) and the OTC under (RVMIF). SP on 20 Oct 2010 was .43.
“During the past year, significant productivity and cost improvements have been realized at the Troy Mine, where we employ over 180 men and women. We remain committed to our employees, the environment and communities in which we operate and live.
Our focus and dedication, combined with proven production at the Troy Mine and the significant potential at the Rock Creek project form the basis of our goal to become a mid-tier precious and base metals producer.
Our plan is to expand production through exploration in and around our Troy mine, through further advancement of our Rock Creek permit.”

History of the Mine and Mill
ASARCO developed a conventional 8,500 ton per day (7,700 mtpd), underground room and pillar operation at Troy in 1980, and operated the mine until early 1993. The mine was shutdown and placed on care-and-maintenance due to low metals prices with the intent of reopening when economics warranted. Late in 2003, when metals prices began to improve, three increasingly detailed engineering and economic assessments were preformed on the known 8.7 million ton reserve (@ 1.57opt Ag & 0.65% Cu). The company made its production decision in April 2004. The optimal mine plan called for a 6,500 ton per day operation that would produce at an average rate of 3.2 Moz of silver, and 26 Mlbs of copper annually, for a mine life of 31¦2 years. Additional resources in the mine may extend the life to at least 5 years. Initial restart capital was budgeted at US$5.3 million, with an additional US$3 million in working capital. Hiring and rehabilitation commenced in May 2004 with first concentrate being produced in December 2004. Initial direct capital was US$ 3.8 million with additional working capital forecast to be approximately US$ 2.2 million. First concentrates were shipped in January 2005 and we expect to reach positive cash flows during the second quarter 2005.
Anticipated Exploration
*Resource expansion through current exploration/program, targeting I Beds and JF deposit at Troy
* Reserve expansion at Troy : C-bed development/production anticipated in Q4 2010

Revett announces completion of “C-Bed” access at the Troy Mine
September 29, 2010: Revett Minerals Inc. (“Revett” or the “Company”) (TSX:RVM/OTCBB:RVMIF) is pleased to announce that contractor Small Mines Development (SMD) has demobilized and completed the access to the “C-Bed” area at the Troy Mine. SMD initiated the 3,100 foot decline in February of 2010 and has completed the project on time and on budget.
While limited production from the higher grade “C-Beds” began this month, higher throughput from the C-Bed area will be brought into the production mix at the beginning of the 4th quarter of this year. Located approximately 370 feet below current workings at the Troy Mine, the “C-Beds” contain approximately 1.9 million oz silver and 13.7 million lbs copper (ore grades averaging 1.61 opt Ag and 0.56% Cu). The table and illustration below identify the approximate location and estimated probable reserves of the “C-Beds”, which are part of the overall reported reserves at the Troy Mine.

Rock Creek and the Environment:
As with most modern mines, the top environmental priority for the Rock Creek Mine will be water quality. The mine is named after the adjacent stream, which is a tributary to the Clark Fork River, which in turn feeds Lake Pend Oreille . Rock Creek will employ, in tandem, two water treatment systems. The primary is an active biological system. This method incorporates what municipal wastewater treatment systems have developed over the years specifically to treat the mine's water. The secondary method is reverse osmosis. Also called RO, this highly engineered plant removes impurities by passing the water through a membrane designed precisely for that task. Water that passes through the water treatment system must meet stringent standards of not only the State of Montana, but also the State of Idaho (because the Clark Fork flows into Idaho ) as well as the Federal Government. The mine's discharge water will be treated to not only meet or exceed drinking water standards, but also the higher standards for fish and other aquatic life. In other words, the discharge will not only meet the letter of the law, it will be clean enough for fish to live in and children to drink. In addition to protecting water quality, the Rock Creek Mine will:
*Utilize a design that considers final reclamation and closure, even prior to turning the first shovel in construction. This ensures environmental protection is given preference throughout the entire life of the operation.
*Employ the long-proven paste technology, incorporating necessary site-specific engineering, to manage the mine's tailings. Storing tailings in the paste form is safer, more stable, brings greater protection to water quality and the environment, and allows the land to be returned to a productive use more quickly. After calculating everything from heavy runoff to a 7.0 Richter Scale earthquake, engineers have determined that over a 1,000-year period, "the likelihood of failure of a paste impoundment is considered negligible, less than 1 in 1 million chances of occurring."
*Protect wilderness, wildlife, and recreational values of the area.
*Take extra measures to reduce unnecessary traffic, substantially reduce dust
*and other air emissions, and reduce fuel consumption.
*Obtain full reclamation bonding, protecting the taxpayers.
*Provide at least 330 high-paying jobs for the area.
*Provide over $22 million per year in taxes, goods, and services purchases.
In reference to ongoing permitting/environmental issues:

Hedge: Spokane Valley, Washington April 28, 2010; Revett Minerals Inc. ("Revett" or the "Company") (TSX:RVM) (OTCBB: RVMIF) is pleased to announce that it has initiated hedging for approximately 20% of its forecasted 2011 copper and silver production at the Troy mine at a price of US$3.60 per pound of copper and US$18.40 per ounce of silver. This tranche of hedging covers approximately 50% of estimated 2011 direct operating costs at the Troy mine protecting us against the possibility of lower metal prices. The unhedged balance of copper and silver production will enable the Company to capitalize on the potential for increased copper and silver prices in 2011.
