Greystar Intercepts 20.21 g/t Gold, 124.86 g/t Silver and 1% Copper Over 5 Metresadmin
Greystar Resources Ltd. reports that diamond drilling continues to encounter significant gold-silver-copper mineralization below and to the south of the oxide/transitional mineral resource on the multi-million ounce Angostura deposit in northeastern Colombia. Highlights include:
– Hole SI10-03, which intercepted 14.5 metres (85.3-99.8m) grading 9.7 grams gold, 62.39 grams silver and 0.33 per cent copper, establishes continuity of the higher-grade sulphide mineralization south of the
oxide/transitional mineral resource in the Silencio Area.
– Hole SI10-02, which intercepted 5.0 metres (488.0-493m) grading 20.21 grams gold, 124.86 grams silver and 1 per cent copper, establishes the
higher grade zone at depth in the Silencio Area.
– Hole QP010-07, which intercepted 1.65 metres (465.0-466.65m) grading 22.3 grams gold, 1,130 grams silver and 0.19 per cent copper, establishes continuity of the higher grade mineralization at depth in
the Los Laches area.
– Hole QP010-05, which intercepted 8.55 metres (601.00-609.55m) grading 13.74 grams gold, 107.28 grams silver and 0.12 per cent copper, establishes that the higher grade zone is open at depth in the Los
“These drill results demonstrate the potential of developing and expanding the significant higher-grade, underground resource at Angostura. Metallurgical test work to date has shown that this sulphide ore can be recovered through conventional processing technology with the prospects of generating revenues from the recoveries of the gold, silver and potentially copper,” commented Steve Kesler, president and chief executive officer of Greystar. “We look forward to compiling the results from the ongoing underground resource expansion drill program with a goal of establishing the economic potential of an underground only operation for the multi-million ounce Angostura deposit. The Company is continuing to work to find the best way to develop the Angostura deposit in an environmentally and socially responsible manner and that is fully compliant with Colombian legislation.”
The latest drill results from the underground resource expansion program include nine holes: five from the Silencio area (QV10-01, Si10-01 and Si10-04) and four from the Los Laches area (QP010-05 to QP10-08). The intercepts from the Silencio area confirm that the high-grade mineralization extends south of the oxide/transitional mineral resource, while intercepts from the Los Laches area continue to show continuity of the higher grade mineralization at depth with the deepest intercepts encountered to date found in hole QP010-05, which returned 13.74 g/t gold and 107 g/t silver over 8.55 metres (5.5 metres true width) from 601 metres downhole and 7.86 g/t gold and 49 g/t silver over 6 metres (3.8 metres true width) from 633 metres downhole and hole QP010-06, which returned 8.70 g/t gold and 45.90 g/t silver over 1 metre from 648.2 metres downhole.

Review by Qualified Person, Quality Control and Reports
The Company employs a quality control program to ensure sampling and analysis of all exploration work is conducted in accordance with the best possible practices. Under these quality assurance measures, drill core is sawn into halves with one half of the core prepped on site and samples shipped to ALS-Chemex Laboratory (ISO 9002 registered) in Vancouver, B.C. for analysis. The remainder of the core is retained for future assay verification. Gold analysis is conducted by fire assay (one assay tonne) using an atomic absorption finish. The laboratory re-assays using the ALS-Chemex protocol, and additional checks may be run on anomalous values. Greystar has independent re-analysis and sample preparation checks run at other accredited laboratories. The Company also introduces background blanks prepared from previously analyzed core samples from the Angostura Project.
