November 16, 2010, Coro Mining Corp. ("Coro" or the "Company") (TSX Symbol:
COP) is pleased to announce that it will commence further reverse
circulation drilling at its Chacay project in early December. Chacay is
located 12 km SE of Teck's Relincho major copper molybdenum project in
Region III, Chile.



Alan Stephens commented, "We are pleased to confirm that we will be
initiating a 3,000m reverse circulation drilling program at our Chacay
porphyry copper project in Chile, in early December. The objective of the
program is to further define the chalcocite enrichment blanket intersected
in previous drilling of the Nacho Zone, as described in our May 4th 2010
news release, as well as to test the Titan 24 induced polarization deeper
primary sulphide targets described in our July 20th 2010 press release. The
program will also test the Lucho and Martin Zones where chalcocite was
intersected in old drill holes. The Company has commissioned an independent
consultant's NI 43-101 report on Chacay and this will be filed on SEDAR
shortly."
