Cited below are a number of accomplishments which contribute to a feasibility study and will facilitate advancing the project towards new mine and mill construction. • Production experience and metallurgical test work demonstrate that a high concentration ratio of gold and other metals can be attained with simple bulk flotation techniques eliminating the need for toxic chemicals such as cyanide. Milling of approximately 68,000 tons of ore has demonstrated the effectiveness of the bulk flotation milling process. • Flotation concentrates shipped to smelters averaged; 4 - l0 ounces gold per ton 200 - 800 ounces silver per ton 10 - 15 percent lead 10 - 15 percent zinc 1 - 1.5 percent copper • Sulfides aze limited to the ore zones and waste rock will not be acid generating. • Based on 23 years of monitoring and analysis, mine water has a pH in the 7.5 to 8.0 *ange attributable to calcite in the ore zones. • Plans call for filtering and returning mill tailings underground as backfill. 4.
