Mansfield Minerals Inc. (TSX-V: MDR)

Mansfield is a well-structured, well-financed, advanced stage junior mining exploration company. The Company is led by a team of experienced prospect generators and deal-makers. Exploration activities have been focused in the Puna of northwestern Argentina since August 1994. The restructuring of Argentina's previously unworkable mining law, combined with its early land position, has allowed Mansfield to be well positioned for the exploration and development of several highly prospective targets. The Mansfield team believes that economic discoveries most often result from hard-won geological insights, continuity and diligence in a company's exploration efforts. It is Mansfield's primary objective to combine all of these elements to build a successful exploration company. www.MansfieldMinerals.com

Probe Mines Limited (TSX-V: PRB)

Probe Mines is a Canadian base and precious metal explorer led by an experienced management team. The Company has assembled a portfolio of quality projects, including the very active McFauld's Lake area base metal projects in Northern Ontario and the Bristol Township gold project in the Timmins West camp. In addition, Probe holds a gold production royalty on a portion of Agnico-Eagle's Goldex project in Val d'Or, Quebec, which is scheduled to commence production in 2008 and represents a potential revenue stream for the company. The Company's strategy is to aggressively explore its key assets to maximize shareholder value, while joint venturing out non-core assets to advance exploration and preserve capital. Probe is currently focused on the McFauld's Lake area where it owns 931 claims covering almost 15,000 hectares.
