Results and Discussion
During the prospecting and geological mapping programs at the Cana Brava property, Cornerstone collected a total of 334 representative rock chip samples with 18 returning greater than 1 g/t Au, 36 returning greater than 0.5 g/t Au and 66 returning greater than 0.2 g/t Au. One sample assayed 64.5 g/t gold with high silver value (42.5 g/t Ag). In addition, 13 samples assayed greater than 100 g/t Ag, 35 samples assayed greater than 30 g/t Ag and 59 samples assayed greater than 10 g/t Ag. There is strong correlation between gold and silver assay results and base metal and epithermal pathfinder element values are strongly anomalous throughout the Cana Brava Breccia area to the west.
Historical soil sampling surveys show a 3 km by 1 km multi-element (Au-Ag-As-Sb-Hg-Cu-Mo) anomaly associated with the Cana Brava lithocap, and Cornerstone's rock sampling program has confirmed gold-silver-copper mineralized zones associated with hydrothermal breccia and silicic ribs. Furthermore, recent work has provided a much better understanding of the nature and controls of alteration and mineralization.
Two mineralized HS epithermal zones have been identified on the Cana Brava property extending over 2.5 km by up to 2.0 km on the Cana Brava Breccia and 1.75 km by 1 km on the East Zone. Economic grade gold and silver assay results from samples collected from outcrop throughout the altered and mineralized zones strongly suggest potential for precious metal epithermal deposits as well as copper-gold porphyry deposits at depth. The East Zone is exposed as intermittent outcrop over an area of 1.7 km by 1 km and is defined by silicic ribs and hydrothermal breccia possibly related to another porphyry system centered on the Fierro Urco lithocap located 2.5 km northeast of the property. The silicic ribs and breccia are associated with advanced argillic alteration and are strongly anomalous in precious and base metals, as well as epithermal pathfinder elements.

All samples were delivered by Cornerstone employees for preparation at Acme Analytical Laboratories (ACME) facility in Cuenca. Rock samples are prepared by crushing 1 kg to 80% passing 2 mm (10 mesh), splitting 250 g and pulverizing to 85% passing 0.06 mm (150 mesh) (ACME code R150). Prepared samples are then shipped to ACME in Vancouver, Canada where samples are assayed for a multi-element suite (ACME code 1F-MS, 15 g split, Aqua Regia digestion, ICP-MS finish).
Quality Assurance / Quality Control (QA/QC)
The ACME preparation facility in Cuenca was audited by Cornerstone. ACME is an ISO 9001:2008 qualified assayer that performs and makes available internal assaying controls. Certified blanks and standards are systematically used as part of Cornerstone's QA/QC program. Rejects and 100 g pulps for each rock sample are stored in Cuenca for future use and controls.
