Prior to this drill program, the Lindero deposit was determined to host 29,953,000 tonnes at 1.08 grams/tonne gold (1,035,900 oz gold in the inferred category) using a 0.6 gram/tonne cut-off. This resource was estimated by Rio Tinto Mining and Exploration Ltd. and audited by Roscoe Postle Associates Inc. in October 2003 (for further information see the Company's news releases of September 22, 2003 and November 26, 2004).

The drilling to date has been successful in expanding the mineralized footprint of the Lindero deposit to the north and southeast, as well as establishing that substantially higher grade mineralized material occurs within the deposit. Intrusive hosted stockwork gold mineralization was also observed extending into the surrounding red-bed sediments along Archibarca trending structures (Az 120º).

With the potential for higher grades and larger tonnages indicated by this most recent exploration work, an aggressive follow-up drill program will be designed upon completion of the current program.

A map of the drill hole locations has been posted on the Company's website and can be viewed at www.mansfieldminerals.com/s/Lindero.asp.

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. The prepped samples were then shipped by Acme to their lab in Santiago, Chile where they were fire assayed for gold.

The Company employs a Quality Control program consisting of re-assaying randomly selected coarse reject samples, insertion of coarse standard samples and blanks.
