Mawson Gold Limited announced metallurgical testwork results from the BATCircle joint research project geometallurgical orientation study of Mawson's 100%-owned Rajapalot gold-cobalt project in Finland. BATCircle is funded by Business Finland in cooperation with several consortium members, including Mawson, the Geological Survey of Finland (GTK) and Aalto University. The full report from BATCircle entitled "Metallurgical testwork for the geometallurgical orientation study of the Mawson Gold's Rajapalot Au-Co project BATCircle Project Report 05 ­ WP1 Task 1.2" by Dehaine et al. (2021) can be downloaded here. Multiple samples from three geometallurgical end-members were chosen for the study from the Palokas and Raja resource areas. At Rajapalot, gold is present as free grains with low silver and copper content (gold is greater than 95% fineness). Gold extraction via cyanidation was over 97% for each sample. There was no sign of preg-robbing for any of the samples. Magnetic and gravity concentration yielded lower recoveries for gold below 50% for all sample types. Rajapalot hosts cobalt minerals that form the most common primary cobalt ore minerals currently exploited, including sulpharsenides (cobaltite) and cobalt sulphides (linnaeite). Mineral processing tests results obtained in this study clearly highlight a mineralogical control over cobalt recovery. Cobaltite is preferentially recovered by flotation (78%-93%) and linnaeite through low amperage magnetic separation (up to 71% cobalt). Flotation has been found to be an efficient technique both for gold and cobalt recovery, with recovery rates and concentrate grades above 90% and 100g/t for gold, and between 23%-63% and above 1% for cobalt, but cobalt recovery as high as 71% has been obtained during the magnetic separation of some ore types. While the test work results described in this study do not allow for the establishment of a definitive flowsheet for the Rajapalot Au-Co project, it provides grounds for future work and the next stage of the geometallurgical campaign, whereby different process paths are tested. Next steps are further continuous cycle testwork to optimize gold and cobalt recoveries, and the development of a definitive flowsheet.
