Stope development and ore production are underway. Westward drift extension will begin in August. Milling and Refining: 70 tons of ore were milled in June, 5 tons being taken from previous stockpiles. Larger demonstration mill facility has been on line now for the past month with improvements being made daily for higher recovery rates.
