Pahtavaara was discovered by the Geological Survey of Finland in 1986 when high gold grade and visible gold were found in outcrop. Prior to the discovery, gold anomalies in till and an extensive “skarn” zone in the bedrock had been detected during regional exploration.
Pahtavaara is located within the Central Lapland Greenstone Belt (CLGB), part of the Fennoscandian shield, which hosts 1700 known incidences of mineralisation in Finland, Sweden, Norway and Russia including around 80 mines. The Central Lapland Greenstone Belt has two gold mines of significance. Agnico Eagle’s Kittila mine (the largest gold mine in Europe) which produced 186,101oz of gold in 2019 and Pahtavaara. Since its discovery there has been over 300,000m of drilling undertaken on the 4km2 Pahtavaara mining licence area and 450koz of gold mined.
Following acquisition of the Pahtavaara Project in 2016, Rupert undertook a comprehensive review of historical data resulting in a new geological model showing the Pahtavaara Project to lie in a domain hosting the confluence of regional scale faults that likely link to crustal scale fracture meshes. Several orders of faulting are represented, which are necessary for crustal scale fluid flow and focussing that can result in deposit formation.
