What's up is these boys have finally found a mine - yes a mine - with drill tested reserves. The next round of drilling will give us some perspective on just how big the tonnage may be. To date the reserve is small but is expected to increase 3 - 5 times the current size with some good core results . We'll have to wait for a news release - but things are very positive right now.

So - MDR comes out with (IMO) a positive news release today. An operating company like Rio Tinto doesn't spend money on these types of investigations "reverse economic study" unless they are confident they are onto something real. I understand Rio's "threshhold" for these types of deposits is 5+ million ounces, therefore, Rio does their homework over the next 3 months to determine the size and if > 5M ounces Rio stays in - if < 5M they vend their interest. MDR shareholders win modestly or win big. What seems to be missing in this overall picture is the company's (MDR's) ability to attract any interest on this emerging story. Time (as always) will tell. PHASE II RESULTS FROM LINDERO, ARGENTINA Vancouver, British Columbia -- Mansfield Minerals Inc. (TSX – MDR) The Company has received assay results tabled by Rio Tinto Mining and Exploration Ltd. from the recently completed Phase II drilling and trenching program on the Company’s Lindero gold project. This program comprised 1,525.62 metres in four diamond drill holes bringing the total drilled on the property to 3,278 metres in ten diamond drill holes. In addition, several new trenches excavated in the area of the Main Zone exposed impressive intervals of significant grade gold mineralization.

This program is anticipated to entail further metallurgical testing, three-dimensional modeling and a logistical review with the objective of assigning a potential range of Net Present Values (NPV) and Internal Rates of Return (IRR) to the Lindero Gold Deposit plus an estimate of the capital cost to finance the project to production. Completion of the reverse economic study is estimated to take two to three months. Management is very encouraged by Rio Tinto’s election to undertake such a study which is generally undertaken by companies only when prior exploration work has indicated the presence of a significant resource that is potentially economic to mine. All gold analyses were performed by fire assay with atomic absorption finish at ALS-Chemex Laboratories in Vancouver. The assay data provided above was communicated to the Company by Rio Tinto.
