Cornerstone Provides Update on Cascabel Copper-Gold Porphyry JV Exploration Project

Cornerstone Capital Resources Inc. announces the following project update for the Cascabel copper-gold porphyry joint venture exploration project in northern Ecuador, in which the Company has a 15% interest financed through to completion of a feasibility study.

HIGHLIGHTS:

• Hole 12 intersects shallow visible copper sulphide (chalcopyrite-bornite) mineralization from 88.4m to current depth of 246.9m *
• Mineralized diorite porphyry intersected at 233.8m, several hundred metres shallower than previously expected. Diorite occurs at a similar depth in Hole 1 (CSD-13-001).
• Extensions to surface mineralization and shallow resource potential realized through recent mapping, trenching and rock-saw channel sampling programs.
• Mobilization of 2nd Rig to site, with exploration drilling planned to test other porphyry centres within the greater Cascabel porphyry cluster.

* Core length; true width of the mineralized zone cannot be determined from the information currently available.
