One waste rock <br />sample was collected inside the mine and one from the waste rock dump, in addition to <br />one ore sample from inside the mine, with site locations annotated. Samples were <br />submitted to Accutest Laboratories in Wheat Ridge, Colorado with chain-of-custody on <br />April 30 and results are still pending. <br />Please let me know if you need further information. <br />Sincerely, <br />e <br />e Eisel, Manager <br />vemco, LLC
