FINLAND – Mawson Resources of Vancouver has the results of preliminary metallurgical tests on drill core from the Palokas prospect at the Rompas-Rajapalot gold project, and those results are “significant”, to quote company president and CEO Michael Hudson.

Gold recoveries of between 95% and 99% (average 97%) were possible using a combination of gravity separation and conventional cyanidation. Between one-quarter and one-half of the gold was recovered in the gravity circuit. The tails were then leached. SGS Minerals, who performed the tests, suggested a flowsheet could include crushing and grinding, gravity recovery, and cyanide leaching followed by CIP and an onsite refining.

The Rompas portion of the project lies near the Arctic Circle, and high grade gold and uranium are found over an area of roughly 10 x 10 km. The initial hydrothermal gold vein discovery was made in 2010 over a strike of 6 km and a width of 200 to 250 metres. In 2013, Mawson discovered a new style of disseminated gold mineralization at Rajapalot, 8 km east of the Rompas vein system.
