Coro Provides Exploration Update Including Initial Results at Chacay

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Aug. 3, 2011) - Coro Mining Corp. ("Coro" or the "Company") (TSX:COP) is pleased to announce that it has completed a 4 hole, 1,975m diamond drilling program at its 100% owned Chacay project and a 24 hole, 4,360m reverse circulation drilling program at its recently acquired Berta Project. The Company also wishes to announce that Angelo Peri, its VP Exploration has resigned to take up a position with a major mining company in Santiago. The Company wishes to thank him for his significant contributions over the past 5 years and wish him well in his new position. Alan Stephens will assume his responsibilities until a suitable replacement is found.

Chacay Initial Drilling Results:

Assay results have been received for the first 2 holes from Chacay as shown in the following table; sampling and assaying of the final 2 holes of the program is in progress.

Hole From To m %CuT g/t Au % Mo % Cu Eq. Ore Type
CHDDH1 198 232 34 0.26 - - - Chalcocite
Hole lost at 232m, in chalcocite mineralization. Au & Mo assays awaited
CHDDH2 192 230 38 0.18 0.02 0.001 0.20 Chalcocite
280 762 482 0.20 0.08 0.005 0.28 Primary
including 280 454 174 0.22 0.13 0.002 0.30 Au rich primary
and 478 762 284 0.21 0.006 0.008 0.28 Mo rich primary
Hole ended at 762m in primary mineralization. (Last sample 0.38% Cu Eq.)
(Cu equivalent calculation based on $2.50/lb Cu, $1,000/oz Au and $12/lb Mo.)

The deep diamond drill hole completed at Chacay has indicated the presence of potentially significant primary mineralization, occurring in apparently separate gold rich and molybdenum rich zones. The copper in the chalcocite intervals of these 2 holes occurred largely as coatings on pyrite.

Berta Drill Program:

The RC drilling at Berta (24 hole, 4,360m reverse circulation drilling program) was completed on time and we look forward to receiving the assay when available.

All diamond drill holes were sampled on a 2m continuous basis, with core samples split on site and one half delivered to the Andes Analytical Assaying (AAA) prep lab in Copiapo by Coro personnel. Pulp samples were transported to the AAA assay laboratory in Santiago by AAA personnel. Samples were prepared using the following standard protocol: drying, crushing to better than 80% passing -10#, homogenizing, splitting and pulverizing a 400 g subsample to 95% passing -150#. All samples were analyzed by sequential assaying for CuT, CuSol and CuCN and for Au, Ag and Mo. A full QA/QC program, involving insertion of appropriate blanks, standards and duplicates was employed with acceptable results. The remaining core was stored at a Coro facility for reference.

Angelo Peri, VP Exploration, Coro Mining Corp, a geologist with more than 26 years was responsible for the design and conduct of the exploration at Chacay, and Alan Stephens, FIMMM, President and CEO, of Coro Mining Corp, a geologist with more than 36 years of experience is the Qualified Person for the purposes of NI 43-101.
