Capstone Reports Additional High Grade Intercepts at Cozamin Mine
VANCOUVER, March 7, 2011 /PRNewswire/ --
- Step-out Drilling on the Mala Noche Footwall Zone Continues to
Encounter High Grades
- Hole U254 Intercepts 5.2% Cu & 180g/t Ag over 8.2m (including 6.0% Cu
& 210g/t Ag over 6.9m)
- Hole U251 Intercepts 1.6% Cu & 19g/t Ag over 22.6m (including 5.1% Cu
& 58g/t Ag over 5.4m)
Capstone Mining Corp. (CS: TSX) today announced drill results for four exploration drill holes on the Mala Noche Footwall Zone ("MNFWZ") at the Cozamin Mine, Zacatecas, Mexico. New drill access and platforms have been added and Capstone intends to ratchet up the underground exploration program. Highlights are presented in the table below and the full results for all four new holes for which assay data has been received are in the table attached.
"We are pleased to report additional results from the Mala Noche Footwall Zone drilling at the Cozamin Mine. These most recent results extend the zone eastward by approximately 100 metres," said Brad Mercer, VP Exploration for Capstone. "We believe the MNFWZ, a splay off the main Mala Noche Vein, provides a near term opportunity to add high grade resources and potential high grade mill feed for the Cozamin operation. We intend to continue our drill program and produce a mineral resource estimate before the end of 2011 to provide a basis to evaluate development options for the MNFWZ," Mr. Mercer added.

Capstone's current plan is to drill 40-50 drill holes on approximately 50 metre centres and underground access has been recently completed to execute this program. The logistics of establishing additional drill access from one of the main haulage ways is being evaluated to see if even larger step-outs can be taken toward the east and down dip, a direction where the highest grade copper-silver mineralization is still clearly open. The intent is to have two drills executing the current 50 metre centre pattern while a third drill probes ahead on a much wider pattern. Capstone will gauge the potential size of this high grade area to determine if additional drills with greater capacity are needed.

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 Brad Mercer, P. Geol., VP, Exploration of Capstone, Qualified Person as defined by NI 43-101. Exploration activities at the Cozamin Mine are carried out under Mr. Mercer's supervision.
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.
