Trelawney Files Resource Report for the Cote Lake Gold Deposit

April 25, 2011 – Toronto, Ontario – Trelawney Mining and Exploration Inc. (the “Company” or “Trelawney”) (TSXV: TRR, Frankfurt: RTW ) announces that it has filed the report entitled: “Technical Report on the Cote Lake Deposit, Chester Property, Ontario, Canada” with regulatory authorities. The report dated April 21, 2011, was authored by William E. Roscoe, P.Eng., and R. Barry Cook, P.Eng., of Roscoe Postle Associates Inc. (RPA). The report includes the initial mineral resource estimate on the Cote Lake Gold Deposit previously released on March 7, 2011.

The main highlight of the report is an Inferred Mineral Resource estimate for the Cote Lake Gold Deposit of 131 million tonnes averaging 1.00 g/t Au for 4.2 million ounces of contained gold at a cut?off grade of 0.3 g/t Au. The estimate and technical report conform to National Instrument 43-101 Standards of Disclosure for Mineral Projects (NI 43-101). The effective date of this mineral resource estimate is March 4, 2011.

The Cote Lake Gold Deposit, located on the Chester Property halfway between Timmins and Sudbury in Northern Ontario, consists of low to moderate grade gold +/- copper mineralization which is associated with brecciated intermediate to felsic, and locally mafic intrusive rocks. Mineralization occurs in the form of disseminated and fracture-controlled sulphides which generally correlate to the gold values. Visible gold is commonly observed. The zones are bleached with the prevalent alteration being feldspathic, chloritic and biotitic. The nature of the alteration and mineralization is indicative of a porphyry-style deposit.

David Beilhartz, Vice President, Exploration for Trelawney Mining and Exploration, a Qualified Person under NI 43-101, has prepared or supervised the scientific or technical information for the property and verified the data disclosed in this press release. William E. Roscoe, P.Eng., of RPA, a Qualified Person under NI 43-101, has reviewed and approved this press release as it pertains to the mineral resource estimate.

Trelawney is a Canadian junior mining and exploration company with a focus on Archean gold deposits. The Company’s current focus is directed towards the development and continued exploration of the Chester Project, located in Chester Township 20 kilometres southwest of Gogama, Ontario.

Copper Mountain Project Unaffected By Japan Earth Quake

Vancouver, British Columbia – March 17, 2011 – Copper Mountain Mining Corporation (TSX: CUM) (the “Company” or “Copper Mountain”) announces that after fielding a number of calls from the investment community, the Company thought it would be prudent to reassure investors that the weeks recent earth quake in Japan has not impacted the Company’s Copper Mountain Project.  All major equipment is on site and being assembled and is on schedule.  Likewise, the Company believes that the Company’s plans for delivery of copper concentrate commencing this summer remain unaffected.

Mitsubishi Materials Corporation (MMC) announced on March 11, 2011 that they have suspended operations at its Onahama copper smelter because of the terrible damage by the earthquake and tsunami, as well as the damages to the infrastructures and logistics for the smelter.  MMC is currently evaluating the situation and yet to  have an estimate of when the Onahama copper smelter will resume its operation. MMC operates three copper smelters, two in Japan, Onahama (subsidiary of MMC) with annual copper cathode production capacity of 258,000 tons and Naoshima with capacity of 225,000 tons, and the PT smelting (subsidiary of MMC) in Indonesia with 300,000 tons. MMC has contracted to purchase 100% of the copper concentrate produced by the Copper Mountain Project. In accordance with the contracts, MMC will implement necessary actions to fulfill its obligations in good faith. MMC’s commitment to the Project is unchanged.

According to the “International Copper Study Group,” Global smelting capacity will expand by 14 percent to 20.68 million tons by 2014, while mining capacity will only reach 18.98 million tons.  According to an article by Reuters on Mar 11, 2011 they reported that Japan was expected to produce 1.6 million tonnes of refined copper in 2011, about 7.6 % of world output. Currently there is excess smelter capacity, the majority of which is in China as the country continues to feed its need for raw materials and refined copper in particular. The Copper Mountain concentrate is very clean and an acceptable concentrate at most smelters.

Construction work on the Company’s Copper Mountain Project continues to proceed on schedule and as planned.  The overall schedule for the project remains unchanged with construction expected to be completed by the end of April 2011, commissioning of equipment is scheduled to occur during May 2011, and full production scheduled to be achieved by the end of June 2011.  Preproduction mining activities are well underway and the Company’s new mining fleet is operating as expected.   Commissioning of the primary crusher, ore stockpile recovery system and pebble crusher is now underway, while installation of the grinding mills is proceeding and are expected to be ready for testing by the end of April.  Mechanical installation in the concentrator is well advanced with the bulk of construction activities directed at piping and electrical activities.

The project currently has 557 workers on site, of which 180 are Copper Mountain personnel and the rest associated with the construction activities.  At full production, the project will employ 271 personnel.
