Capstone Mining Corp. has released its financial results for the three and nine months ended Sept. 30, 2011. All figures are shown in U.S. dollars, unless otherwise specified. Net earnings for the quarter were $21.1-million and cash flow from operating activities was $38.9-million. Capstone ended the quarter with cash on hand of $484.2-million and no long-term debt. Copper production for the quarter at Capstone's two operating mines, Cozamin and Minto, totalled 20.6 million pounds of copper in concentrates (19.9 million pounds of payable copper) at an estimated total cash cost of $1.39 per payable pound.

Capstone will hold a conference call Tuesday, Nov. 8, 2011, at 11:30 a.m. ET (8:30 a.m. PT) to discuss these results; call-in details are provided at the end of this release. This release should be read in conjunction with Capstone's unaudited interim consolidated financial statements and management's discussion and analysis for the three and nine months ended Sept. 30, 2011, which are available on Capstone's website. An updated corporate presentation, including results to Sept. 30, 2011, will also be available at the company's website.

"Net earnings were significantly higher than the same quarter a year ago," said Darren Pylot, Capstone president and chief executive officer. "The increase was driven by a gain on derivative instruments versus a loss in the comparative quarter, though this was partially offset by lower earnings from mining operations due to higher depletion and amortization, and higher taxes."

"We had a solid quarter from an operational standpoint, with both of our mines achieving record throughput levels this quarter, allowing us to remain on target to meet our full year 2011 guidance," continued Mr. Pylot. "On the Santo Domingo project development front, we released the prefeasibility study, staffed the key project management positions, awarded the environmental impact study contract, commenced the drill program required for the next stage of development and are advancing to the bankable feasibility study under the timeline detailed in the PFS."

Highlights

Financial and production highlights for the three months ended Sept. 30, 2011

Recorded net earnings of $21.1-million or six cents per common share which included:

Operating highlights for the three months ended Sept. 30, 2011

Cozamin, Mexico

It produced 9.9 million pounds of payable copper at a total cash cost of $1.24 per pound of payable copper.

Following completion of an initial mineral resource estimate for the Mala Noche footwall zone (MNFWZ) in the second quarter, work continued on a follow-up mineral resource estimate incorporating additional drill data. The new resource estimate will be complete in the fourth quarter and used as the basis of engineering studies currently under way.

It completed 9,204 metres of surface diamond drilling in nine holes on various targets and 5,914 metres of underground diamond drilling in 15 holes targeting the MNFWZ. Underground drilling is continuing at the MNFWZ with two rigs for the remainder of 2011 and into 2012. The MNFWZ mineralized structure remains open to the east and down dip.

Minto, Yukon

It produced 10.0 million pounds of payable copper at a total cash cost of $1.55 per pound of payable copper.

It continued stripping of the next pit in the mining sequence, the Area 2 pit, with ore production anticipated in the second quarter of 2012.

Following completion of a mineral resource estimate in the second quarter incorporating drilling results from Wildfire/Copper Keel and combining these areas with area 2/118 (now known as Minto South deposit or MSD), work continued in the third quarter on a follow-up mineral resource estimate incorporating additional drill data. The new mineral resource estimate will be complete in the fourth quarter and used as the basis for the phase VI PFS currently under way.

It completed 6,695 metres of exploration diamond drilling in 18 holes bringing the year-to-date totals to 38,416 metres in 112 drill holes. Drilling in the third quarter focused mostly on testing new exploration targets and is expected to continue into the fourth quarter as long as weather conditions allow. Drilling is anticipated to restart in early 2012.

Santo Domingo, Chile

It completed a prefeasibility study that contemplates an 18-year mine life, with an after-tax internal rate of return of 22 per cent, net present value of $1.1-billion (U.S.) at an 8-per-cent discount rate and a three-year payback with average annual production of 144 million pounds of copper, 4.1 million tonnes of iron and 15,000 ounces of gold.

The core Chilean management team for the project has been recruited, which includes the general manager announced in August. By quarter end, a health, safety, environmental and communities manager was in place, and a project manager joined in mid-October. A legal and permitting manager is committed to start by early November. This core leadership team has both operational and project development experience in mines and projects belonging to Codelco, Barrick, Kinross, BHP and Anglo American in Chile. The contract for the preparation of the Santo Domingo environmental impact study was awarded to Knight Piesold.

A 12-hole geotechnical drilling program and a 12,000-metre infill drilling program are under way to provide support for the bankable feasibility study stage.

Kutcho, British Columbia

During the third quarter, detailed engineering continued to support the compilation of the environmental application. This includes optimizing the access road design, completion of a hydrogeology-drilling program and excavating test pits required for the soils baseline study.

Electromagnetic anomalies generated by a versatile time domain electromagnetic (VTEM) survey flown earlier this year were drill tested in the third quarter. The results are still being compiled, but no new economically significant mineralization was discovered and no further drilling is contemplated in 2011.

Corporate activities

During October, 2011, the company entered into copper forward purchase contracts at $3.08 per pound to offset its remaining outstanding copper forward sales contracts. This decision was made to allow the company to participate in any future copper price increases. As at Oct. 31, 2011, 100 per cent of the outstanding copper forward sales contracts had been offset. The offsetting copper forward purchase contracts entered into in October, 2011, locked in an approximate $1.0-million gain on an equivalent number of copper forward sales contracts.

Outlook

Capstone reaffirms full year 2011 production guidance. With year-to-date production of 58.5 million pounds of copper in concentrates and both mines presently operating on plan, the expectation is that production will reach 80 million pounds for the year. In the fourth quarter, production at Cozamin is expected to be above third quarter levels as the mine plan calls for higher grade ore. At Minto, the successful contract precrushing will continue until permanent improvements are implemented, and continuing high throughput is expected to offset the processing of lower grade material from stockpile. Cost guidance remains at the previously revised $1.45 to $1.50 per payable pound of copper.

Work on engineering studies at Cozamin that will apply economic parameters to the MNFWZ resource block model to determine economic viability continued in the third quarter, with completion targeted in the fourth quarter of 2011.

At Minto, driven by a new mineral resource estimate, Capstone has a PFS (phase VI PFS) scheduled to be completed in early 2012. The preliminary resource estimate released in the second quarter determined the initial scope of the PFS. A more robust estimate incorporating additional drilling, originally targeted to be complete in the third quarter, is under way with completion expected shortly.

In addition to the phase VI PFS, a separate internal scoping study is being conducted of a larger open pit/milling scenario. The resource update and the result of the internal scoping evaluation of the larger throughput scenario are expected in the fourth quarter of 2011.

At Santo Domingo the critical activity for the fourth quarter is the bidding process and awarding of the bankable feasibility study. A request for proposal (RFP) is being prepared and the contract award is scheduled to be completed by year-end.

Development activities at Kutcho for the remainder of 2011 will be focused on the environmental and socio-economic assessment process and consultations toward permitting mine development.
