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.

Ingelshyttan no. 9
Ingelshyttan No. 9 is a exploration permit of 79.5 hectares. According to SGU, the copper content in the mines was 9.2% copper and 48.8% iron. Within the area there are a large number of closed iron and copper mines, the last mine was closed in the 1950s.

The exploration permit is located only 2.5 kilometers from the Lovisa mine, which has been mined for lead and zinc since 2004.

There are a number of tailings on the survey permit. All of them contain increased levels of iron in varying amounts, in some cases over 30%. Three of these tailings also contain between 1 and 2% copper as well as up to 1,125 ppm gold and high levels of REE metals.

Big Rock Exploration AB has carried out magnetic surveys at Ingelshyttan and found two magnetic anomalies in connection with the larger mines in the area. Both anomalies are approximately 200 to 250 meters long and 100 to 150 meters wide and are separated by less than 100 meters.
These two magnetic measurements largely coincide with an almost 500 meter long electrically conductive anomaly.

Big Rock Exploration AB has obtained from external expertise three recommended drilling locations to drill a total of approximately 300 meters distributed over three holes. The Company intends to drill these holes as soon as financing is secured as well as perform an electrical I.P. survey to investigate whether the electrical anomaly is greater than what the company is aware of.

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.
