11-23 - Environmental license granted for Cascabel project in
      Ecuador
=======================================================================

Mount Pearl, NL, Canada: Cornerstone Capital Resources Inc.
("Cornerstone") (TSXV-CGP) (F-GWN) (B-GWN) (OTC-CTNXF) today announced
that the Ministry of Environment (ME) of Ecuador has granted the
environmental license for Cornerstone's Cascabel gold-copper project
located in northern Ecuador (see news releases of February 17 and March
29, 2011). The license is valid for the 4-year initial exploration
phase of the 5,000 hectare concession. A prospecting program has begun,
where stream sediment geochemical anomalies are being followed up to
locate and characterize the source of the anomalies and to define the
geological environment. Results of this first-step reconnaissance work
will be announced in the Fall.

Cascabel project

The Cascabel project is located in the Imbabura province in northern
Ecuador, approximately 120 km north of Quito. The property comprises a
single 50 km2 concession which is 100% owned by Cornerstone. The area
is underlain by Cretaceous -- Tertiary volcanic and sedimentary rocks
which are intruded by a granodioritic stock. A well-defined
multi-element (gold-copper-lead-zinc) anomaly measuring approximately
10 km2 has been identified with associated large areas of
silica-sericite-pyrite-clay alteration. Several secondary stream
sediment anomalies have also been identified within the property
limits. Historic stream sediment samples have returned assay results
ranging from trace up to 3.36 g/t Au and 456 ppm Cu. Rock grab samples
of floats and outcrops collected by previous owners have returned assay
results ranging from trace up to 1.03 g/t Au, 4.4 g/t Ag, 1.90% Cu and
0.71% Zn. Coarse free gold occurs in most streams throughout the
property. Recent rock sampling (14 samples) by a previous owner
returned anomalous gold (5 samples > 0.1 g/t Au, up to 1.8 g/t Au),
silver (2 samples > 15 g/t Ag, up to 80.7 g/t Ag), copper (12 samples >
130 ppm Cu, up to 0.21% Cu) and zinc (8 samples > 130 ppm Zn, up to
1.0% Zn). Cornerstone considers the area to be prospective for both
porphyry and skarn-style mineralization.
