Steam Engine Further Metallurgical Test Results

• Coarse-grind metallurgical test work: Metallurgical test program augments existing metallurgical data with stress-testing and gravity recovery information and assists current tolling discussions with a third-party gold mining and processing operation. • Stress-testing involved metallurgical testing at a coarse grind size of 150 microns, compared to standard testing conducted at a finer 75 micron
