FINLAND – Toronto-based SCANDINAVIAN GOLD has shipped three batches of nickel-copper-PGE concentrate to separate companies to determine which pressure acid leach (PAL) technology might provide optimum recovery. The concentrate was produced by the company’s mini-pilot program at its Keivitsa property in Finnish Lapland. One of the methods to be tested has been used in commercial production, and the other two are at the demonstration stage.
Keivitsa is one of the largest mineral discoveries in Finland’s history, hosting a probable reserve of 120 million tonnes within an indicated resource of 150 million tonnes and an inferred resource of 315 million tonnes. As such, it constitutes one of the world’s major undeveloped sulphide nickel deposits. More information about Keivitsa is available at www.ScandinavianGold.com.
Scandinavian Gold is pursuing two processing options simultaneously for Keivitsa ore. The first involves the production of a bulk concentrate suitable for PAL treatment. The recent mini-pilot program constitutes part of this scenario. The second scenario involves production of separate nickel and copper concentrates suitable for sale to a smelter. Bench-scale metallurgical tests for the smelter scenario are expected to be complete in June.
