However, following BCSC's review, La Mancha is retracting the supplemental information which had been provided in the May 16th 2011 press release concerning Sedgman's economic analysis of the extra 1.2Mt of heap leach residue grading 2.06 g/t Au (for 79,475 oz of gold contained) which remained in the inferred category as of March 31, 2011. La Mancha acknowledges that an inferred resource cannot be used to suggest an economic value in the content of a feasibility study, even when discussing upside potential, as is the case on page 3 of its May 16, 2011 press release.
