Noteworthy U occurrences are reported from the Kalan region in western central Kalimantan. OECD-NEA/IAEA (2005) reports in situ resources of 6 797 t U RAR and 1 699 t U EAR-I including some 5 800 t U recoverable resources (RAR + EAR-I). CEA/COGEMA has explored the Kalan region in the early 1970s and estimated resources of 1 260 t U at a grade of 0.27% U for Eko-Remaja, some 500 t U for Lemajung, and around 100 t U for boulders (“Rirang boulders”) along the Rirang River. Exploration is conducted by BATAN, a state-owned institution. A pilot beneficiation plant has been installed 2 km N of the Remaja prospect.
