Mansfield is a mining development company led by a team of experienced prospect generators and deal-makers. The Company has focused its activities in the Puna of northwestern Argentina since August 1994 where management first conducted preliminary reconnaissance during January 1994. Impetus for exploration here was the structural and tectonic similarities of the Puna to the Great Basin of the western United States. Timing of this initial foray into northwestern Argentina coincided with the Argentinean government initiating the process of overhauling a previously unworkable Mining Law.

Although several companies recognized the potential of the area and opened offices in Salta during this period, Mansfield is the only company to maintain a permanent presence since 1994 and is viewed by the locals as a fixture in their community. Mansfield's staff has over 15 years of experience with the legal and land tenure system, as well as the socio-political environment.

In 1999, Mansfield's exploration team discovered the Lindero gold property and after subsequent exploration and development published an NI 43-101 Reserve Estimate in June 2008. AMEC Americas Limited completed a prefeasibility study for Lindero in March 2010 which indicates that Lindero will provide strong financial returns at a gold price of US$850/oz. Management has initiated the mine permitting process and expects receipt of a mine permit in Q4/10. The Company will continue with the full bankable feasibility process which will include water studies, additional metallurgical optimization, condemnation drilling and foundation studies. Management believes that deposits such as Lindero which are heap leachable and non capital intensive remain desirable projects to garner attention, particularly if global reflation efforts result in further weakening to the US dollar index and the subsequent strengthening of the price of gold.
