DAKOTA CONCLUDES SUCCESSFUL BULK HEAP LEACH TEST OF SULFIDE ORES

 DENVER, Dec. 8 /PRNewswire/ -- Dakota Mining Corp. (AMEX; Toronto: DKT) announced today that it had successfully concluded a bulk heap leach test of sulfide ores at its Gilt Edge mine in South Dakota. In October 1992, 42,000 tons of sulfide ore having a grade of 0.059 ounces of gold per ton was crushed to 90 percent minus 1/4 inch and placed under conventional cyanide heap leach. Previous laboratory metallurgical studies had indicated that a +55 percent recovery was achievable within a 2 year period.
 After leaching for 383 days, a 49.4 percent gold recovery rate has been achieved. Regression analysis of these results demonstrate that a 61.8 percent recovery rate will be achievable at the end of a two year period. This result exceeds the earlier laboratory forecasts of +55 percent. An independent metallurgical consultant has verified Dakota's sulfide test gold extraction projections.
 Dakota also stated that no enhancements were utilized to improve the gold recovery. However, the company did undertake certain precautionary measures by adding buffering agents to the ore prior to its placement upon the pad to ensure that the material under test did not produce acidic conditions. This was very successful.
 Dakota's president and chief executive officer, Alan Bell, reported "Dakota has now commissioned an independent engineering firm to prepare a feasibility study on the Gilt Edge orebody. The company believes that a 61.8 percent recovery at present gold prices may well allow it to develop all or part of this very well defined resource of approximately 45 million tons at a grade of 0.04 ounces of gold per ton, containing 1,800,000 ounces."
 Dakota Mining is a publicly held, Denver-based mining company with operating mines in the United States. Its common shares and warrants are listed and traded on the American and Toronto stock exchanges under the symbol DKT.
