Greystar Resources Files Appeal to Reinstate Environmental Impact Assessment at Angostura Project, Colombia

VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 04/29/10 -- Greystar Resources Ltd. (the 'Company') (TSX: GSL)(AIM: GSL) announced that further to its news release dated April 26, 2010, the Company has filed an appeal with the Ministry of the Environment, Housing and Territorial Development (MAVDT) to reinstate its Dec. 22, 2009 Environmental Impact Assessment (EIA) in respect of the development of an open pit gold-silver mine at the Company's Angostura project in Colombia and accept that the Company has complied with all legal requirements to have the project proceed.

Among other strong legal considerations, the appeal challenges the retroactive application of the Feb. 9, 2010, modification to the mining law (Law 1382 of 2010). The appeal is wide ranging with a primary focus on legal and technical arguments. Greystar believes it has designed the Angostura project optimally to minimize the project's impact on the environment and water sources. The appeal seeks to have the EIA reviewed as filed on Dec 22, 2009. The basis for which are comprehensive studies made in accordance with the environmental requirements and the detailed management plans of impacts provided in the EIA which demonstrate the feasibility of the project. Under the regulatory appeals process MADVT must respond to the appeal within fifteen (15) working days.

Steve Kesler, President and CEO, commented, 'We are confident that the Colombian Government will consider the appeal from a broad perspective. We believe that the Colombian Government wishes to encourage investment in mining that is balanced with environmental protection. Colombia has the right to enact new legislation; however, it must ensure that existing investors are not damaged by retroactive application of such legislation. Transparent and predictable laws are necessary to encourage foreign investment in Colombia. We will continue to work with the MAVDT to resolve issues of concern and ensure that the impact of the Angostura project on Paramo is minimized whilst ensuring the financial viability of the Angostura project.'
