The initial 43-101 resource estimate at Lindero of 29,953,000 tonnes inferred at 1.08 grams/tonne gold (1,035,900 oz gold) using a 0.6 grams/tonne cut-off and based upon 11 drill holes, was calculated by Rio Tinto Mining and Exploration Ltd. and audited by Roscoe Postle Associates Inc. in October 2003. Subsequently, the Company has completed an additional 104 holes comprising approximately 30,000 metres of drilling. This program has been successful in expanding the footprint of the deposit significantly. A current resource estimate is now being calculated combining all of the results received to date.

On January 22, 2008, a Mansfield delegation toured the Kinross Gold Refugio heap leach gold mine located in central Chile, 250 km southwest of Lindero. Refugio is of particular interest to the Company as it exhibits striking similarities to Lindero including geology, deposit geometry, leach characteristics and grade distribution. Operating metrics at Refugio will provide a useful template for establishing the economics of the Lindero deposit.

There has been a recent announcement by the Argentinean federal government of the revoking of an exemption of a 5% net tax on the export of unrefined gold. This tax policy has been in place since 2001 and only deposits put into production prior to 2001 are affected by the loss of the exemption. All deposits put into production after 2001 have been subjected to this tax. Deposits such as Veladero, Gualcamayo, Manatial Espejo, Huevos Verdes, and Pirquitas all have this tax contemplated in their feasibility reports.

Gordon Leask, President & CEO, comments:

"The Company is fortunate to own a deposit of Lindero's quality in a very acquisitive gold market. Lindero has many favourable physical characteristics including size, grade, grade distribution, recovery rate, and amenability to leaching as well as location. Upon the completion of the updated resource estimate and scoping study, I believe the shareholders will enjoy the true value of the Lindero deposit."

Security - Chain of Custody and Quality Control

Two metre lengths of HQ core samples were halved with a diamond saw and bagged at the field facility. The bags were tied with plastic color-coded security ties. Sample bags were then placed in shipping boxes and couriered by company vehicle to the Acme Analytical Laboratories S.A. prep lab in Mendoza, Argentina. Samples are prepped and fire assayed at Acme facilities in Mendoza, Argentina. Part of the pulps is shipped by Acme to their lab in Santiago, Chile for further assaying. The Company employs a Quality Control program consisting of re-assaying, in two different assay laboratories, randomly selected coarse reject samples and pulp samples, and also insertion of a pulp standard sample, a coarse blank and a duplicate of each 20 samples in the field.
