Mawson Resources Limited (TSE:MAW) (OTCMKTS:MWSNF) said Wednesday that new tests on samples from its Finnish projects show that the metals can be extracted in a low-cost and energy-efficient manner.
The company is conducting its first liberation study for cobalt from its Raja and Palokas projects in Finland, as well as the first project-wide liberation work for gold.
Results indicated that over 90% of gold and cobaltite were liberated and concentrated through enhanced gravity recovery into heavy concentrates, suggesting that mineralization is favourable towards low-impact and energy-efficient gravity pre-concentration.
The first phase of the study assessed the mineral liberation characteristics of gold and cobalt from Mawson’s project so that processing methods to separate them from waste minerals can be designed.
CEO Michael Hudson called the initial results “very encouraging.”
Five samples, one from Palokas and four from the Raja prospect, were selected based on representative gold and cobalt grade and host rock composition for qualitative mineral liberation test work, the company said in a statement.
Qualitative liberation of gold and cobaltite into gravity concentrates was high, exceeding 90% when ground to an average grain size of 50 micron.
“Work under the BATCircle research program continues for the Rajapalot project with batch flotation and leach tests planned next,” Hudson told investors.
The work was completed by the Mintec Outokumpu mineralogical laboratory of the Geological Survey of Finland and funded in collaboration with the BATCircle research project. As part of a broader program, Mawson and BATCircle will each invest €250,000 for advanced exploration and metallurgical studies on the Rajapalot gold-cobalt project.
The BATCircle research project aims to coordinate research on the battery metal circular economy from exploration to recycling with the goal of creating a market of least €5 billion in Finland.
