Jasenie is a gold-tungsten project located approximately 90 kilometres northeast of the Hodrusa-Hamre licence area on the southern side of the Nízke Tatry mountains, north of Jasenie village.
The Company filed an exploration claim application, which was successfully granted to Prospech in May 2017. The project is partly in a National Park and partly in a National Park buffer zone. The environmental protection levels permit exploration and mining subject to conditions to be imposed by the Environmental Bureau of Slovakia.
The history of modern mining starts at the end of 1950s, when an 18 kilometre long and 400 metre to 1,000 metre wide scheelite-gold anomaly was identified on the southern slopes of the Nízke Tatry mountains. Exploration adits with a total length of 13 kilometres were driven in the 1980s.
Quartz veins up to 9.0 metres wide and with an average 1.5 metre width contain the highest gold concentrations, whereas scheelite (tungsten) occurs predominantly in stockwork zones. Vein-type ore is reported to contain several grams per tonne gold; with local enrichment up to several tens of grams per tonne. Tungsten content is reported to locally reach as much as 4%.
The highest reported gold assays come from rock chips collected in Spiglova valley (72.00 - 77.50 g/t gold). The average gold grade out of 33 rock chips collected during the latest, 1980’s exploration is reported to be 9.07 g/t gold.
PERIPHERAL PROSPECTS IN JASENIE TENEMENT
Jasenie – Soviansko – Pb-Ag – mined since 1638 until 1943. Exploration in 1950s defined resources of 115kt of Pb ore @ 3.65% Pb and 75 g/t Ag. Main Pb mineral is galena.
The deposit is hosted in migmatites and paragnesisses. Veins are trending E-W and are dipping 70-80° SE. Average thickness of the veins is 10-70cm. The deposit was explored to 75 metres from the surface.
Jasenie – Lomnista – Au–Sb – is hosted in crystalline rock complex (paragneisses, migmatites). Veins are generally trending NW-SE steeply dipping to SW (70-90°), 0.1-1.6m wide and 150-250m long. Vertical extend of the veins is 70m. Highest grade ore was found on the interstection of flat and steep structures. The main ore mineral is stibnite, ore shoots in the deposit reportedly contained 4-6% up to 12% Sb in some places.
Jasenie -Sucha – Au-Sb – is a small occurence of Sb-Au mineralisation. It is composed of three short NE-SW veins dipping 30° SE. No other data are available.
