Sjaule (U)

The Sjaule project consists of a single ~201Ha exploration licence which is located within the County of Jämtland, north-central Sweden (figure 1). The project falls wihtin the Hotagen Inlier uranium province and is respectively located 13km NE and 30km NNW of Mawson Energi AB high grade Flistjarn and Hartogen Projects.

Uranium mineralisation was originally discovered by the SGU at Sjaule in 1975 during a uranium directed regional reconnaissance sampling program. Following the return of anomalous results a program of follow-up airborne radiometrics, mapping, scintillometer and gamma ray surveying plus rockchip sampling was implemented resulting in the successful identification of uranium bearing outcrops (Photos 2 & 3). Multiple drill targets were defined however, no drilling was completed.

Mineralisation at Sjaule is mainly related to a northeast-trending, steeply dipping fracture zone measuring 700m x 950m which has developed at an oblique angle to a major local thrust front. Thrusting resulted from the juxtaposition of a sequence of Paleozoic sedimentary rocks over older Precambrian felsic intrusive basement (figure 2). Well developed mylonite and breccia which are also fluorite and uranium bearing are present along trust surfaces. Uranium is present as pitchblende (uranium oxide) and brannerite (uranium - calcium - titanium – iron complex). Results of five surface rock samples collected by the SGU in 1976 over the main 20m x 300m mineralised zone returned up to 0.57% U3O8 with an average of 0.22% U3O8.
