Wed Aug 15, 2007 Positive Feasibility Study For Continental's Wholly Owned Xietongmen Project
NPV OF US$232 MILLION & IRR OF 16.5%
August 15, 2007, Vancouver, BC - Continental Minerals Corporation ("Continental" or the "Company") (TSXV: KMK: OTCBB: KMKCF) announces the positive results of the Feasibility Study by independent engineering firm Aker Kvaerner E&C on the Xietongmen Copper-Gold Project (the "Xietongmen Project"). Continental holds 100% of the Xietongmen Project, located 240 km west of Lhasa in the Tibet Autonomous Region ("TAR"), People's Republic of China.
The study is based on measured and indicated resources in the Xietongmen deposit, as announced in January 2007; January 2007 US dollars; a US dollar to Chinese currency exchange rate of 7.8; and long term metal prices. Two scenarios - mining by owner and mining by contractor - were assessed and both gave positive results. Results presented here are for the contract mining scenario.

Continental's President and CEO Gerald Panneton said: "Management is very pleased with these positive results. By working closely with our internationally recognized consultants, the design institutes in China, keeping in close contact with the local government and communities, we have been able to effectively advance the project through the feasibility stage. Our goal is to design and permit an efficient and environmentally sound operation that will bring economic benefits to the region.
We also believe that there is potential to extend the mine life. Additional targets on this prospective property are currently being drilled with seven rigs, including the recently discovered Newtongmen deposit."
MINE PLAN
The study recommends a 40,000 tonnes per day copper concentrator to process ore mined by open pit method. Processing facilities, concentrate storage and truck loadout facilities, repair shops, administration and maintenance facilities, assay laboratory, water treatment facilities, cafeteria and a clinic would be built at site. Copper recovery will be accomplished by flotation, producing a 25% copper concentrate.
A 250 km extension of the rail line from Lhasa to Rikaze, the second largest city in the TAR, has been approved by the TAR government. Depending on when the rail line extension will be completed, the final concentrate product would be trucked by way of a two lane paved highway that passes near to the southern part of the property to the nearby city of Rikaze (Shigatse) or to the city of Lhasa. A truck loadout facility would be constructed to store the concentrate and load it into railcars and ship it via rail to the Jinchuan refinery at Jinchang in the Gansu Province of China for treatment. Recovery of other metals will be possible through the treatment at the Jinchuan refinery. Under the plan, power would be provided by the regional power authority of the TAR, which is currently preparing their long term plan to provide 100 megawatts to the Xietongmen Project.
The pre-production period is expected to last 8 months. A three-stage pit operation is proposed for the development of the mine, with each stage lasting 3-5 years. A total of 480.1 million tonnes of material would be moved over the mine life, including 182.1 million tonnes of ore, at a strip ratio of 1.64. The mill feed would be 12.4 million tonnes in the first year, ramping up to an annual feed of 13.6 million tonnes by year 4. The deposit mineralization is 89% primary copper (hypogene), with approximately 11% enriched copper (supergene) and less than 1% oxide material. The plan is to mine most of the 17.4 million tonnes of supergene material in the first stage.
Upon completion of the permitting process, the project would take approximately 24 months to construct, employing a construction workforce of 2,500. During operations, the direct workforce would be approximately 460 people. After operations, the closure plan would take 18-24 months to implement, which would be followed by post closure monitoring.
Continental plans to implement training programs to enable as many workers as possible to be sourced from local communities, of which there are several including the city of Rikaze with a population of +100,000. Additional workers will find housing and residence in larger communities like Rikaze, and during operations would be transportion will be facilitated by bus to the work site. Continental has been actively consulting with local communities and other key stakeholders over the past year. Associated management plans are also being developed to address findings from the assessment raised during the consultation process.
ADDITIONAL DETAILS
Royalties of 4% of the gold revenue and 2% of the copper revenue and a resource depletion allowance of 1.5 RMB/tonne of ore milled have been applied. Corporate tax of 10% has been applied to the model with a five-year tax-free period. It was assumed 10% of the capital cost would be recovered once the deposit is mined out. Straight-line depreciation of 90% was applied.
An owner run scenario was also assessed giving positive results with an NPV of US$228.8 million and IRR of 15.6%. Under the owner run scenario, the capital cost is US$531 million and the operating cost is US$7.29/tonne.
Sensitivity analyses indicate that the Xietongmen Project is most sensitive to changes in copper price.
