Capstone Reports Significant Drill Results From Mala Noche Footwall Zone, Cozamin Mine
VANCOUVER, September 20, 2010 /PRNewswire-FirstCall/ --
- Hole UG-ING-22 Intercepts 4.4% Cu & 85g/t Ag Over 17m, Including 5.3% Cu & 103g/t Ag Over 13.5m
Capstone Mining Corp. (CS: TSX) today announced assay results confirming a new high grade copper-silver discovery at its Cozamin Mine in Zacatecas State, Mexico. Exploration drilling along the Mala Noche vein system is delineating a new mineralized structure in the footwall rocks to the main Mala Noche Vein (which hosts the current mineral reserves at Cozamin). This new mineralized system is in close proximity to active mine workings and is easily accessible, should mineral reserves be established.
Highlights of assays from the Mala Noche Footwall Zone (MNFWZ) are summarized in the table immediately below and the full results for new holes and historic holes are provided in the attached tables.

(x) Intervals reported are intercept lengths, true widths are estimated to be similar to those reported. "The results from drilling of the newly discovered Mala Noche Footwall Zone at the Cozamin Mine are very encouraging," said Stephen Quin, Capstone's President. "The mineralization remains open to expansion, and drilling is continuing. In parallel with the continued exploration, Capstone has commenced estimating mineral resources for this area, since the close proximity to existing mine workings offers potential for near term production." Mala Noche Footwall Zone The MNFWZ, a vein and breccia complex separate from the main Mala Noche Vein, is associated with the margins of a rhyolitic dyke intruding into the footwall rocks of the Mala Noche system and has been traced in drill holes over 700 metres along strike and 200 metres in the dip direction. This subsidiary structure intersects the main Mala Noche vein system west of the San Roberto shaft at about a 30 degree angle and it is still open to the east, up-dip and down-dip. The current mineral resources and mineral reserves at the Cozamin Mine are entirely hosted in the main Mala Noche vein, and this new discovery of the MNFWZ represents a new style of mineralization not previously identified at Cozamin. The discovery of this new style of mineralization presents an opportunity for the identification and discovery of new, similar, mineralization in other areas where similar intersecting structures are known. Update on 2010 Exploration Plan As stated on April 21 , 2010, the current 2010 exploration plan for Cozamin in 2010 and beyond is twofold:
1. The focus of the first half of 2010 was on drilling targets that are
in close proximity to the Mala Noche vein system and current mine
workings, which means any new resources could easily be drill defined
from existing workings. The discovery and expansion of the MNFWZ is
the first product of this program, and drilling is continuing.
Underground drilling has also commenced in an area east of the
widest, higher grade part of the Cozamin Mine, currently being mined
by Avoca methods. This exploration is being conducted on claims
acquired by Capstone in 2009.
2. The second exploration priority is to evaluate and drill test
exploration targets within Capstone's large land package surrounding
the Cozamin mill, but which cannot be accessed through the current
system of mine workings. This is the first such exploration by
Capstone since the acquisition of the Cozamin Mine and surrounding
land package. More than a dozen targets have been identified through
mapping, sampling and geophysics and sufficient field work has been
completed to begin drill testing about half of these. Drilling is
expected to commence before the end of September 2010.
The 2010 exploration expenditures are budgeted at US$3.7 million, exclusive of underground development costs.

Quality Assurance/Quality Control
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 Cozamin Mine are carried out under the supervision of Brad Mercer, P. Geol ., VP Exploration of Capstone. Analyses for copper, zinc, lead, silver and gold were completed by ALS Chemex using the following method. The entire sample is crushed to a minimum of 70% minus 10 mesh. A 250g subsample of the crushed material is then pulverized to 85% minus 200 mesh. Gold and silver grades are determined by gravimetric fire assay using a 50g charge taken from the pulverized material. Copper, zinc and lead are determined by ICP analysis after 4 acid digestion of a 0.4g subsample of the pulverized material.

Such factors include, among others, risks related to actual results of current exploration activities; changes in project parameters as plans continue to be refined; future prices of mineral resources; possible variations in ore reserves, grade or recovery rates; accidents, labour disputes and other risks of the mining industry; delays in obtaining governmental approvals or financing or in the completion of development or construction activities; as well as those factors detailed from time to time in the Company's interim and annual financial statements and management's discussion and analysis of those statements, all of which are filed and available for review on SEDAR at www.sedar.com. Although the Company has attempted to identify important factors that could cause actual actions, events or results to differ materially from those described in forward-looking statements, there may be other factors that cause actions, events or results not to be as anticipated, estimated or intended. There can be no assurance that forward-looking statements will prove to be accurate, as actual results and future events could differ materially from those anticipated in such statements. Accordingly, readers should not place undue reliance on forward-looking statements.
