Capstone Reports Final Phase 1, Drill Results - More High Gold Grades at Minto North

VANCOUVER - Hole 09SWC474 Intercepts 3.0% Cu & 6.0g/t Au Over 32.3m (including 4.7% Cu & 9.8g/t Au Over 8.8m)

Capstone Mining Corporation (CS: TSX) today announced the assay results for 18 new exploration drill holes completed at its high grade Minto copper-gold mine in the Yukon. Included in these results are more high grade copper-gold intercepts from the recently discovered Minto North deposit, and significant intercepts from Area 118 and from the south end of the Copper Keel trend. Some of the best new intercepts at Minto North were at shallow depths and, overall, these results should enhance the Minto Mine Phase IV expansion study currently well underway and slated for completion later this year. Highlights from this latest batch of results are tabulated below, while complete results are attached.

The estimated true thickness would be approximately 87% of the intercept length, except SWC09-449 where it would be approximately 82%. (xx) Reported intersections contain samples with coarse visible gold.

“These excellent results wrap up a very successful exploration program completed in the first four months of 2009,” said Stephen Quin, President & COO of Capstone Mining. “The 2009 program discovered and delineated the exceptional Minto North deposit, discovered and delineated a high grade extension to the Ridgetop deposit, and continued to advance the Copper Keel trend,” he added. “However, the outstanding results of the year are those from Minto North, where our exploration team discovered a thick, high grade, shallow zone of copper mineralization with some exceptional gold grades.”

Drill Program

To date in 2009, 14,966m of diamond drilling in 86 holes have been completed, including six oriented geotechnical holes in support of a pit wall stability study as part of the Phase IV expansion study, which will assess potential new open pit mining centres on the Minto North, Area 2/Area 118 and the Ridgetop deposits. Drilling and geophysical surveying is set to resume at Mino North and the surrounding region in late June. New mineral resource estimates for the entire Minto property, including Minto North, are nearing completion, the results of which are expected to be announced in June 2009. These estimates will include all drilling completed to date, including almost all 2009 drilling.

Quality Assurance

The technical information in this news release has been prepared in accordance with Canadian regulatory requirements set out in National Instrument 43-101 and reviewed by Stephen P. Quin, P. Geo., President & COO for Capstone Mining Corporation. The exploration activities at the Minto project site are carried out under the supervision of Brad Mercer, P. Geol., V.P. Exploration (Canada) for Capstone.

The analytical method for the copper and silver analyses is aqua regia digestion of the samples followed by atomic absorption spectroscopy. Gold is analysed by fire assay fusion with atomic absorption spectroscopy finish for gold. Analyses are carried out by ALS Chemex in North Vancouver. When visible gold is noted in drill core samples or regular fire assay values appear abnormally high, the pulp and screen metallic assay method is used to determine the total gold content and gold contents of different size fractions. This is considered industry best practice when dealing with coarse gold mineralization where a nugget effect is suspected. This determination is accepted as the most representative value and is used in the assay database for resource calculations. Blank and standard samples are used for quality assurance and quality control. Where more than two check samples assay outside expected ranges, the entire batch is re-assayed. After the completion of planned drill programs at Minto, random check assays will be carried out by Acme Analytical of Vancouver.
