The Zar and Ivan oxide deposits host 4.2 million tons grading 1.85% copper. An additional 1.6 million tons grading 3.85% copper has been defined in the Ivan sulphide zone.
Minera plans to heap leach the oxide ores from the Zar and Ivan deposits. An open pit mine plan and reserve study are being prepared with a feasibility study scheduled for completion by April, 1990.
In Costa Rica, Minera has outlined a northerly extension at the company’s Bellavista-Montezuma gold property. The company has outlined a preliminary open pit reserve of 14.2 million tons grading 0.05 oz gold per ton. “If the indications of a major extension are substantiated by further drilling, then the reserves for Bellavista could increase to the 20- to 25-million-ton range,” David Hutton, vice-president of exploration for Minera said.
A bulk sampling program is in progress. The company also plans to complete a revised open pit and ore reserve study by the New Year.
A private placement of 9.6 million Minera shares has been arranged with the company’s largest shareholder, Rayrock Yellowknife Resources (TSE) and Westlake Industries (VSE). The issue will raise $12 million of which $6 million is budgeted for the Ivan and Bellavista feasibility studies, continued exploration and the retirement of debt.
