Assays from the remaining holes in the large diameter (PQ) 33-hole diamond core drilling program have confirmed the continuity of the mineralisation and robustness of the geological model used to prepare the previously reported maiden Mineral Resource estimate of 21.2Mt @ 1.4% Li2O and 170ppm Ta2O5.
Comprehensive metallurgical test work program now set to commence on 4 tonnes of sample collected from the drilling program.
Liontown Resources Limited (ASX: LTR) is pleased to advise that it has received the remaining assays from a diamond core (PQ) drilling program completed late last year at its 100%-owned Kathleen Valley Lithium Project in WA. The drilling program consisted of 33 holes for a total of 2,896m and was designed to provide an additional 4 tonnes of sample for further detailed metallurgical test work.
The latest assays are for holes KVDD0026 - KVDD0042, which were drilled at the Kathleen's Corner prospect (Figure 1/Appendix 1), and are consistent with earlier results from the program (see ASX release dated 4th February 2019) which confirmed:
The continuity of the mineralisation and the robustness of the geological model;
Continuity of the high-grade mineralisation; and
The potential for grades to increase with depth.
Comprehensive metallurgical test work will now commence on samples from the diamond core holes, which were all sited to ensure that material representative of the optimised, open-pittable portion of the global Mineral Resource is assessed.
Preliminary test work on 300kg (six holes) of sample confirmed the potential to produce a saleable spodumene concentrate from Kathleen Valley (see ASX release dated 12th November 2018). The next stage of test work, which is expected to be completed by mid-2019, is designed to:
Provide input data for the next stage of feasibility studies;
Optimise grade/recovery performance and produce a spodumene concentrate to a minimum 6% Li2O grade;
Confirm that a tantalum concentrate can be economically recovered; and
Provide sample for potential customers and off-take partners.
A recently commenced 16,000m Reverse Circulation drilling program aimed at further expanding the Mineral Resource and increasing the mine life (see ASX release dated 29th January 2018) will test for further strike and dip extensions of the mineralisation intersected by the metallurgical holes.
A Scoping Study (see ASX release dated 29th January 2018) has confirmed the potential for a viable mining and processing operation at Kathleen Valley, and the Liontown Board has approved the commencement of further feasibility studies. Results from the next phase of metallurgical test work and the resource expansion drilling will be incorporated into a full Definitive Feasibility Study, due for completion in early 2020.
