Hällefors, Kobergs, Jugnasbo/Sala4, Sweden
(GOLDSEARCH EARNING 70%)
Under the terms of the joint venture agreement with Tumi Resources, Goldsearch may earn up to 70% interest in the Jugansbo, Sala 4, Kobergs and Hällefors properties located in the Bergslagen District of Sweden. Bergslagen lies immediately to the northwest of Stockholm and covers an area of approximately 200 kms east-west by 150 kms north-south. Bergslagen is highly mineralized and is one of the most important ore districts in Europe, containing deposits of iron, manganese, base-metal and silver.
The initial minimum commitment by Goldsearch will be to fund a SkyTEM airborne electromagnetic and magnetic survey that is currently underway over the Properties (the "EM Survey"). The EM Survey consists of flight line spacings of one hundred metres (100m) and is being undertaken to identify prospective drill targets.
Also under the terms of the joint venture agreement, Goldsearch must incur expenses of Euros 100,000 (including the EM Survey) within year 1; Euros 300,000 in year 2; and total cumulative expenses of Euros 1,000,000 by the end of year 3.
About the Properties:
Jugansbo (1,406 hectares) and Sala4 (226 hectares). Located 12 kms to the north of Sala, Sweden's biggest historic silver producer. Cu-Pb-Zn-Ag mineralization has been mined from small pits and shafts accessing massive sulphide occurrences within the same limestone formation that hosts the Sala deposit.
Kobergs (539 hectares). Silver, lead, zinc and iron sulphides and tungsten mineralization have been discovered within a 2 km- long sequence of dolomite and limestone. The licence secures the historic Björntjärn mine, a small zinc producer.
Hällefors (794 hectares). Hällefors is Sweden's second largest historic silver producer after Sala and produced in excess of 480,000 ozs. The silver mines are located about 8 kms north of Hällefors township and 210 kms west north-west of Stockholm, Sweden, in the westernmost part of the Bergslagen mineral district. Silver-lead-zinc mineralization occurs over a 2.5 km long by 0.5 km wide area consisting of two principal belts, the eastern and western mines.
The eastern mine consists of a complex of underground and surface workings over about 150m length and 20 - 30m width. It may project to the more recent Jan Olafs and Alfrida mines, a further 100m to the WNW. The workings at the original mine are known to extend at least to 95m depth. The western and middle mine ores occur in fissures that are perpendicular to, or at very steep angles to, the trend of the rhyolitic volcanics. The veins consisted of independent bodies of galena and sphalerite that extended to depths of between 147m and 200m. The first mining was performed in the eastern silver mine during 1635-1726, and the first mine in the western zone was developed in 1668. The Jan Olofs and Alfrida mines in the eastern zone were opened in the 1880's.
No production figures are available for the eastern silver mine, but during 1878-1896 and 1915-1917, 9,000 tonnes were produced from the western silver mines grading approximately 1,560 g/t Ag, 12% Zn and 38% Pb. Records indicate that between 1639 and 1852, Hällefors produced just over 480,000 ozs of silver, and between 1843 and 1852 it produced 36.8 tonnes of lead. LKAB (1982) estimated that 96,000 tonnes have been mined, but no average grade was provided. More recently, Boliden extracted, by means of a decline, a small but high grade body of mineralization from the field. It is reported that about 4.5 tonnes of silver, 2,200 tonnes of zinc and 2,700 tonnes of lead were recovered.
