Dear Agoracom Family,

I want to thank all of you for your patience with us over the past 48 hours and apologize for what was admittedly a botched launch of our new site.

As you can see, we have reverted back to the previous version of the site while we address multiple forum functionality flaws that inexplicably made their way into the launch.

To this end:

1.We have identified 8 fundamental but easily fixable flaws that will be corrected in the coming week, so that you can continue to use the forums exactly as you've been accustomed to.

2.Additionally we will also be implementing a couple of design improvements to "tighten up" the look and feel of the forums.

Sincerely,

George et al

Capstone Reports 2nd Batch of Minto Drill Results-New High Grade Area Identified at Ridgetop

1.9% Cu over 17.7m, incl. 4.2% Cu over 7.1m (starting at 30.2m) in area previously thought to be low grade

VANCOUVER, BRITISH COLUMBIA--(Marketwire - April 7, 2009) - Capstone Mining Corporation (TSX:CS) today announced the assay results for 18 new exploration drill holes completed in areas south of the Minto open pit. Included in these results are several high grade copper-gold intersections from the southeast portion of the Ridgetop deposit, an area not previously known for high grade mineralization. Many of these new drill intercepts are at shallow depths and are much higher grade than expected; they are anticipated to positively impact the Minto Mine Phase IV expansion study slated for completion later this year.

"The latest results from the high grade Minto Mine in the Yukon continue to build on the successes of 2008," said Stephen Quin, President & COO of Capstone Mining. "We have expanded the main high grade portion of the Ridgetop deposit, discovered in 2008, to the east and have now discovered a second, previously unknown high grade area, to the southeast of the previous Ridgetop resource. These impressive copper-gold intercepts, at such shallow depths, are anticipated to positively impact our mining assessment of this area as a shallow, open pit source of mill feed for our Phase IV expansion project that is currently being evaluated."

Drill Program

To date in 2009, two drill rigs have completed 13,400m of drilling in 74 holes, including 6 oriented core holes in support of a pit wall stability study as part of the Phase IV expansion study, to assess potential new open pit mining centres in and around the Area 2/Area 118 and Ridgetop deposits. Drill assessment in support of the Phase IV study is now complete and both drill rigs have moved to the Minto North discovery area to begin systematically drilling off a mineral resource on this 2009 discovery. Both rigs will remain at Minto North for the completion of the Phase 1 exploration program and budget. After a brief shut down for freshet, both drills will infill the Minto North deposit in support of a National Instrument 43-101 mineral resource estimation before year end. Several drill holes have also been completed in the Copper Keel area, the results of four of which are reported herein. However, with the discovery of the shallower mineralization at Minto North, further evaluation of Copper Keel (likely an underground mining target) has been deferred until the potential of Minto North is more fully defined.

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.
