Two applications for exploration permits were lodged in January 2008 in the Liberec District in northern Czech Republic. The Osečná–Kotel and Plouznice applications cover uranium deposits previously identified by Czech state uranium mining body Diamo, in the area of known uranium deposits south of Straz pod Ralskem where Diamo has a uranium processing plant which is currently on care and maintenance. Both these applications have been rejected and appeals have been lodged. Submissions are being prepared citing the recent Supreme Administrative Court finding which over-turned the rejection of applications for exploration licences by another company. Uranium mineralization is developed in sandy sediments of the basal part of the Cretaceous formation, which lie within a fault-bounded block overlying crystalline basement. The sedimentary complex is up to 230 metres thick. Mineralisation is predominantly in extensive fairly flat-lying lenses 0.5 – 4.5 metres thick within coarse fluvial and lacustrine sandstones. Previously both ISL and conventional uranium mining in similar deposits in the area have been carried out, with grades reported to be in the range 0.04 – 0.12% U3O8. Previous detailed exploration indicated the existence of large areas of uranium mineralisation in shallow flat-lying sedimentary strata within the area of the application. Based on information published in 1991 and previous mining in the area, the company has an exploration target at Osečná–Kotel of 20,000-25,000 tonnes contained U3O8 @ average grades of about 0.1% U3O8.
Based on information published in 1991 and previous mining in the area, the company has an exploration target at Plouznice 15,000-20,000 tonnes contained U3O8 @ average grades of about 0.1-0.12% U3O8.
