Mongora Yields More Positive Results for Greystar Resources

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Aug. 19, 2010) - Greystar Resources Ltd. (the "Company") (TSX:GSL)(AIM:GSL) is pleased to announce additional drill results from the Mongora prospect located three kilometers to the south of the Angostura gold-silver deposit in the California mining district, Colombia.

To date, Greystar has completed a total to 15,490 meters in 44 drill holes on the Mongora prospect; 21 of these drill holes have been completed in 2010. Mongora is similar to the Angostura deposit as it hosts higher-grade gold mineralization including 116 grams gold over 2.0 metres, 22.2 grams gold per tonne over 2.0 metres and 12.35 grams gold over 1.6 metres within broader zones of lower-grade gold mineralization. The Mongora drill program is focused on a gold-in-soil geochemical anomaly that extends to the West and Southwest and connects with a gold-in-soil geochemical anomaly in the Violetal area. Currently an area of 40 hectares is being drilled of a gold-in-soil geochemical anomaly that extends over an area of over 200 hectares. The limits of mineralization have not been defined either on surface or at depth. The delineation of significant oxide gold mineralization at the Mongora prospect could be very important for the Angostura project.

Note: (i) - Down hole width, not corrected but based on drill holes
and structural dip of the mineralization, the interval is
considered to be close to true width.


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.

The above information has been reviewed and approved by Mr. Frederick Felder, P.Geo., a "qualified person" as that term is defined in National Instrument 43-101 and Guidance Note for Mining, Oil and Gas Companies issued by the London Stock Exchange in respect of AIM companies, which outline standards of disclosure for mineral projects. 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 Columbia.
