The bedrock geology in the Kuusivaara exploration permit consists of Svecfennian metasediments and both syn- and post-tectonic granites. A quartz monzogranite is mapped in the north east of the permit area. In 1972, the SGU recorded the presence of radioactivity from the peat boys in the Kuusivaara area. Subsequent scintillometer surveys, pitting and trenching identified six areas of strong radioactive responses within a total area of about 1,500 x 500 metres. The strongest responses were associated with small peat bogs several 10’s to 100’s square metres in size. One sample from the peat bog contained 5.8% uranium, and six other samples contained 0.17% to 3.76% uranium.

In subsequent work, All Star Minerals undertook scintillometer traverses over the areas, which confirm the presence and location of radioactive peat bogs. The source of the uranium is not yet known. Peat bogs in northern Sweden are known to concentrate uranium from drainages over uranium-bearing bedrock. All Stars’ initial exploration programme, which will include both geochemical sampling and further scintillometer traverses, will be designed to identify the source rock areas and targets for drilling, which will be tested by about 1,000 metres of drilling in 2009.
