The Pulju Greenstone Belt (PGB), located on the northwesternmost edge of the Central Lapland Greenstone Belt (CLGB) in Finland, bears significant potential for Ni-sulfide deposits. The Paleoproterozoic differentiated komatiites of the Mertavaara Formation host the Hotinvaara Ni-prospect which is the...
