Projects
Big Rock Exploration AB is working on five interesting exploration permits in Sweden.
Nybergsfältet
Nybergsfältet is located in Nora municipality, Örebro county. Within the area, iron has been mined between 1858 and 1968 in several mines. According to SGU, iron contents up to 65% were mined as well as copper. Previous holders of exploration permits over the area drilled three holes in 2005–2006 and demonstrated iron grades of over 50% and up to 1.95% copper and 2.14 ppm gold.
Big Rock Exploration AB intends to carry out geophysical survey on the Nybergsfältet to investigate magnetism and electrical conduction and send a number of rock samples for analysis to investigate the conditions for rare earth metals within the exploration permit.
In case of good results from geophysical surveys and rock samples, the company intends to drill a number of holes to investigate the extent of metals in the ground.
Rostberget
"Rostberget ”is located in Ludvika municipality, Dalarna. In this area, rock samples from slag heaps have been carried out and show levels of the following:
Silver 205 ppm, gold 1.26 ppm, copper 0.43%, iron 28.3%, lead 4.06%, zinc 7.04%. (source SGU)
Uvberget
"Uvberget" is an exploration permit for 40 hectares in Hedemora municipality, Dalarna. In 2017, SGU (Swedish Geological Survey) took rock samples in this area from slag heaps. The samples gave results of 13% zinc and 0.5% copper. The company intends to carry out geological surveys in the area to investigate the extent of the anomaly and, after that, plan drilling targets to further ensure the area's high potential.
Ingelshyttan no. 9
"Ingelshyttan nr 9" is an exploration permit of 79.5 hectares. According to SGU, it has a content of 9.2% copper. There are several closed mines in the area, the most recent mine was closed in the 1950s. There are a number of slag heaps on the permit and from some slag heaps from the old mines there are rock samples with very high levels of sulphides. The area is only 2.5 kilometers from the Lovisa mine.
Grecksåsar
Grecksåsar is located in Nora municipality, Örebro county. Within the exploration permit there are two old iron mines where zinc, lead and silver also occur according to SGU. Previous holders of exploration permits over this area drilled a hole in 2005–2006. 2.83% copper was found in the hole.
Big Rock Exploration AB intends to carry out geophysical surveys on Grecksåsar to investigate magnetism and electrical conduction and to send a number of rock samples for analysis to investigate the conditions for copper, zinc, lead, silver, iron and rare earth metals within the exploration permit.
In case of good results from geophysical surveys and rock samples, the company intends to drill a number of holes to investigate the extent of metals in the ground.
