Subject: Comments to the Draft Guidelines for the Application of UNFC-2009 to Uranium and Thorium Resources: from Radoslav Vukas, Republic Geological Inspector, Ministry of Mining and Energy, Republic of Serbia
19 August 2015
1. The present document "UNFC-2009 U & T Guidelines for public comment; 25 June 2015 ", in my personal opinion is built on a very exceptional basis.
2. General information work, the current classification of mineral resources / reserves of uranium in Serbia (as well as information on resources / reserves available on the Web Site IAEA) was performed on the basis of the provisions of the Ordinance - Role book on Classification and Categorization of Solid Mineral Reserves of Raw Materials and Keeping a File on Them (issued in former SFR Yugoslavia, 1979).
3. Pursuant to the provisions of current Regulations (in Serbia, a new Role Book in preparation) division of deposits (uranium ore body) was made based on the size and complexity of forms (layer, regular and irregular lenses, wires, stockwork, fault zones, etc.), Uniformity distribution of uranium (very steady, balanced, medium patchy, uneven and very uneven) and the degree of continuity of the mineralization, in five (5) groups (deposits / ore bodies uranium).
4. Further classification current resources / reserves (from the Law, from 2011) in the categories A, B and C1, for each group deposits / uranium ore bodies, shall be carried out under special conditions (based on drilling, mining operations, or combined .. .).
5. Framework harmonization and presentation resources uranium, comes close look at the following table, noting that previous research has not proven A category, which reflects the degree of exploration and the need for further systematic approach this issue:
6. In accordance with Section 5.6.2. Geologic type of deposits (UNFC-2009 U & Th Guidelines for public comment, 25 June 2015) current and historical data of geological research (funded and literature) indicate that the uranium bearing Serbia related to (1) granites and (2) sediments (medium-grained sandstones) in their vicinity, then for (3) metamorphic complex and (4) volcanogenic complex of Tertiary age. A small number of uranium mineralization and unexplored is tied for phosphate and black shale and other geological environment.
7. In section 2.1.3 Thorium (UNFC-2009 U & Th Guidelines for public comment, 25 June 2015), in the second section, with monazite, I think that perhaps needs to be emphasized and mineral bastnezit (fluorine rare earth carbonate), which is as ore mineral in the form of ore vein and carbonatites (dissemination) and contains about 0.1% Th, especially in terms of the actual current geological radiometric exploration of mineral occurrences of rare elements (earth).
8. In section 5.1.4 Human Resources (UNFC-2009 U & Th Guidelines for public comment, 25 June 2015), it may be necessary to emphasize the following words: with competent, adequately trained and properly trained personnel....
9. I would like, as a final comment, to state that it was clearly noted the lack of qualified and specialized personnel for the respective geological and other studies of uranium and thorium.
