Mr. Kappes is a recognized authority on gold and silver metals heap leaching. In addition to providing engineering and design work on numerous projects, he has directed laboratory and field tests on several projects that have subsequently become major precious metal mines.

Mr. Kappes will be eligible to receive all of the compensation and benefits provided for non-employee directors, including those described in Annex A to the Company’s Compensation Committee charter.

The Company is currently in the process of negotiating the proposed acquisition of a metallurgical laboratory from KCA, the value of which exceeds $120,000.
