Capstone Reports High Grade Copper-Gold Discovery at Minto Mine

Capstone Reports New High Grade Copper-Gold Discovery at Minto Mine Discovery Hole 10SWC635 intercepts 2.4% Cu & 0.8g/t Au over 10.8m (including 3.7% Cu & 1.0g/t Au over 5.2m)

VANCOUVER, July 15 /CNW/ – Capstone Mining Corp. (CS: TSX) today announced assay results from a new high grade copper-gold discovery, called “Wildfire”, at its Minto Mine. The Wildfire discovery was made as a result of testing of an extensive geophysical anomaly detected during a deep penetrating IP survey being conducted over the Minto Mine property. Mineralized intercepts from three additional step-out holes, similar to the discovery hole, are being prepared for shipment to the assay lab and a third exploration drill is being sent to the mine to accelerate the assessment of this new discovery. Highlights from Wildfire discovery hole 10SWC635 are summarized in the table below.

“The discovery of yet another high grade copper-gold zone reinforces the tremendous prospectivity of the Minto Mine property,” said Stephen Quin, President of Capstone. “Geophysics suggests that the Wildfire discovery could have a significant aerial extent, is relatively shallow, and the grades from the first hole are very encouraging. With three more mineralized intercepts within the geophysical anomaly, we have elected to bring in a third drill rig to rapidly assess the potential of this exciting discovery.”

Wildfire Discovery – Minto Mine

As reported on June 23, 2010, Capstone is undertaking a property-wide Titan-24 deep penetrating Induced Potential (“IP”) survey. The survey is wrapping up this week but preliminary results identify a number of chargeability anomalies in areas untested by previous drilling. The Wildfire anomaly is one of the strongest and most extensive IP anomalies yet identified at Minto. Based upon the size, strength, and location with respect to known deposits, a decision was taken to drill Wildfire based upon the preliminary IP data only.

The Wildfire IP chargeability anomaly measures more than 900 metres north-south by more than 250 metres east-west. Previous drilling at Copper Keel North, Copper Keel South and at Airstrip, all with good results, had skirted the perimeter of the recently delineated Wildfire anomaly, but had not tested the main portion of anomaly. The discovery hole, 10SWC-635 reported herein, and three subsequent holes completed to date are targeted within the main part of the anomaly. More drilling is required to determine if mineralization is continuous between the known mineralization previously identified at Copper Keel North, Copper Keel South, and Airstrip. Capstone’s most recent 3D geology model for Area 2 suggests continuity between Area 2 and Copper Keel North, and now geophysics suggests continuity right across to Wildfire and Copper Keel South. Drill road construction has commenced in order to facilitate a systematic drill pattern at Wildfire across its entire extent.

The mineralization at Wildfire is principally comprised of chalcocite, along with lesser bornite, chalcopyrite and native copper. Due to the presence of coarse native copper, additional screen analysis assays are being conducted to ensure such material is not being lost in the routine assay approach. Similar chalcocite-dominated mineralization was defined in the upper mineralized zone at Ridgetop and returned excellent recoveries and concentrate grades. Metallurgical testing will be required to determine the metallurgical characteristics of the Wildfire discovery.

Additional Minto Drilling

In addition to more drilling at Wildfire, drilling at Minto for the remainder of 2010 will also focus on increasing the confidence in and extending deeper mineral resources at Minto East, Area 2 and Copper Keel, as well as testing other Titan-24 IP anomalies already identified. Further step out and delineation drilling will be required in order to fully define the limits of the mineralization in all areas and to increase confidence levels to a point sufficient to support a conversion to mineral reserves, if economic factors warrant, by demonstrating both continuity of grade and thicknesses.

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 of Capstone Mining Corp. The exploration activities at the Minto project site are carried out under the supervision of Brad Mercer, P. Geol., V.P. Exploration of 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 mineral 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 Inspectorate-IPL of Vancouver.
