Greystar Intercepts 1,805 g/t Silver, 5.09 g/t Gold and 0.83% Copper Over 2 Metres at La Plata

VANCOUVER, BRITISH COLUMBIA--(Marketwire - April 6, 2011) - Greystar Resources Ltd. (TSX:GSL)(AIM:GSL) ("the Company") reports that significant silver-gold-copper mineralization has been encountered from its initial diamond drill program on the La Plata property. La Plata is located southwest and along strike of the multi-million ounce La Mascota gold-silver-copper discovery in northeastern Colombia. Highlights include:

  • Hole PL10-01, which intercepted 12.85 metres (16.15-29.0m) grading 85.13 grams silver, 1.24 grams gold and 0.19% copper followed by 8 metres (29.0-37.0m) grading 32.59 grams silver, 5.20 grams gold and 0.64% copper;
  • Hole PL10-04, which intercepted 18.15 metres (11.85-30.0m) grading 32.24 grams silver and 4.64 grams gold;
  • Hole PL10-12, which intercepted 2.0 metres (322.0-324.0m) grading 1,805 grams silver, 5.09 grams gold and 0.83% copper and;
  • Hole PL11-01, which intercepted 8.2 metres (198.8-207.0m) grading 24.22 grams silver, 1.73 grams gold and 0.41% copper.

"The first pass drill results from La Plata show the potential of the emerging multi-million ounce La Mascota gold-silver trend to the southwest," commented Steve Kesler, President and Chief Executive Officer of Greystar. "Our wholly owned La Plata property adds yet another dimension to our property holdings in northeastern Colombia. It is also important to note that this project is at a lower elevation than both the La Bodega/La Mascota property and the Angostura Project, and that it is not subject to development restrictions associated with Páramo legislation."

As previously announced Greystar acquired the rights to earn 100% of the La Plata property in 2009. On February 7, 2011 the Company completed all its obligations under the agreement and now owns the property outright.

The gold, silver, copper mineralization discovered on the La Plata property is part of the mineralizing system following the northeast faulting trend, parallel to La Baja creek. This mineralization gives rise to the Angostura and La Mascota deposits some 4 kilometres to the northeast. Mineralization is structurally controlled and is hosted in Triassic - Jurassic intrusives and in the Precambrian gneisses. The mineralization is associated with hydrothermal fluids possibly generated by small irregular porphyry bodies of 8.4 ± 0.2 Ma and 9.0 ± 0.2 Ma (U-Pb) (Mantilla et al., 2009) age. At La Plata this mineralization occurs in sheeted faulted veins striking to northeast and east-west, steeply dipping to north and south. The veins are commonly silicified and allunitized with halos of Illite-Sericite and Kaolin and smectite alterations. At surface, the mineralized structures have returned grab sample values as high as 9.3 g/t gold, 2,030 g/t silver, 2% copper, 736 parts per million ("ppm") molybdenum, 0.4% lead and 1% zinc. During late 2010 and in February of 2011 Greystar completed an 18 hole drilling program of which 11 returned significant intercepts.

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.

Mr. Felder is a geologist with more than 40 years of industry experience and a member in good standing with the Association of Professional Engineers and Geoscientists of British Colombia.
