High Neodymium Praseodymium Ore Grade at New Targets
Sydney, Oct 9, 2017 AEST (ABN Newswire) - Hastings Technology Metals Limited (
ASX:HAS) advises that assay results were received from its major 2017 drilling programme, mainly at two new targets, Yangibana and Simon's Find (see Figure 1 in the link below). Both are held 100% by Hastings and neither was included in the Company's July 2017 JORC Resources.

4m at 1.94%TREO including 0.93%Nd2O3+Pr6O11
4m at 1.43%TREO including 0.69%Nd2O3+Pr6O11, and
4m at 1.31%TREO including 0.61%Nd2O3+Pr6O11
- Best intersections at Simon's Find include:-
3m at 1.10%TREO including 0.63%Nd2O3+Pr6O11, and
2m at 1.11%TREO including 0.61%Nd2O3+Pr6O11
- Both targets host mineralisation with high Nd2O3+Pr6O11:TREO ratios of 44-51% and up to 52-57% respectively
- Simon's Find assays also indicate significant niobium grades with best intersections including:-
12m at 2.24%Nb2O5, and
5m at 1.88%Nb2O5
INTRODUCTION
Both have very high ratios of Nd2O3+Pr6O11:TREO. Neodymium and praseodymium are the primary rare earths of Hastings and these are significant discoveries.
The Yangibana prospect (see Figure 1 in the link below) lies within Mining Lease M09/165 and was briefly drill-tested in 2015. Subsequent mapping and rock chip sampling established the potential for economic rare earths mineralisation over approximately 2.0km of strikelength within the ML, despite the narrow width of the structure at surface.
111 reverse circulation (RC) holes (6,500m) and 3 diamond drillholes (249.4m) were drilled during the recent programme, testing 1.95km of strikelength of discontinuously outcropping ironstone (see Figure 2 in the link below).
Selected results from the RC drilling at Yangibana are shown in Table 1 (see link below) and confirm the high Nd2O3+Pr6O11:TREO ratio of between 44% and 51%.
Drillhole parameters are provided in Appendix 1 (see link below)and detailed assays are provided in Appendix 5 (see link below).
Simon's Find Prospect
Simon's Find prospect (see Figure 1 in the link below) covers a discontinuously outcropping ironstone unit within Exploration Licences E09/2018, E09/2129 and E09/1943 that extends over 2km between the Bald Hill Southeast JORC resource within M09/157 to the north and the Fraser's North JORC resource within M09/158 to the south.
Previous mapping and rock chip sampling identified this as another potential target for high Nd2O3+Pr6O11:TREO mineralisation, albeit with narrow width at surface.
70 reverse circulation holes (2,895m) and 4 diamond drillholes (263.6m) were drilled during the recent programme, testing some 2.35km of strikelength of discontinuously outcropping ironstone (see Figure 3 in the link below).
Selected results from Simon's Find drilling are shown in Table 2 (see link below).
Significantly, the mineralisation at Simon's Find has the highest ratio of Nd2O3+Pr6O11:TREO of all deposits and prospects identified to date over the Yangibana Project, ranging from 52% to 57%.
The Simon's Find drilling also returned high grade niobium results associated with and adjacent to the rare earths mineralisation, but over wider mineralised intervals including those shown in Table 3 (see link below).
Drillhole parameters are provided in Appendix 2 (see link below) and detailed assays are provided in Appendix 6 (see link below).
Yangibana North
Hastings also recently completed a twelve-hole infill drilling programme into the shallow portion of the Yangibana North deposit (Hastings 70%) to provide samples for metallurgical testwork. Best results from this drilling are shown in Table 4 (see link below). The Nd2O3+Pr6O11:TREO ratio at Yangibana North ranges from 25% and 31%.
Drillhole parameters are provided in Appendix 3 (see link below) and detailed assays are provided in Appendix 7 (see link below).
Auer
Results from eight RC holes drilled into the northern extension of the Auer deposit. High grade results were returned from this new target as shown in Table 5 (see link below), with Nd2O3+Pr6O11:TREO ratios of between 33% and 48%.
Drillhole parameters are provided in Appendix 4 (see link below) and detailed assays are provided in Appendix 8 (see link below).
Drilling is ongoing at Auer and Auer North.
Bald Hill
Final assays have been received from the 2017 reverse circulation drilling programme at Bald Hill. Hole BHRC325 returned an intersection of 10m (83-93m) at 1.11% TREO including 0.43% Nd2O3+Pr6O11. This hole is the south-westernmost hole drilled at Bald Hill to date and indicates that this mineralisation remains strongly open to the southwest.
TERMINOLOGY USED IN THIS REPORT
TREO is the sum of the oxides of the light rare earth elements lanthanum (La), cerium (Ce), praseodymium (Pr), neodymium (Nd), and samarium (Sm) and the heavy rare earth elements europium (Eu), gadolinium (Gd), terbium (Tb), dysprosium (Dy), holmium (Ho), erbium (Er), thulium (Tm), ytterbium (Yb), lutetium (Lu), and yttrium (Y).

About Hastings Technology Metals Ltd
Hastings Technology Metals Ltd (ASX:HAS) (FRA:5AM) is advancing its Yangibana Rare Earths Project in the Upper Gascoyne Region of Western Australia towards production. The proposed beneficiation and hydro metallurgy processing plant will treat rare earths deposits, predominantly monazite, hosting high neodymium and praseodymium contents to produce a mixed rare earths carbonate that will be further refined into individual rare earth oxides at processing plants overseas.
Neodymium and praseodymium are vital components in the manufacture of permanent magnets which is used in a wide and expanding range of advanced and high-tech products including electric vehicles, wind turbines, robotics, medical applications and others. Hastings aims to become the next significant producer of neodymium and praseodymium outside of China.
Hastings holds 100% interest in the most significant deposits within the overall project, and 70% interest in additional deposits that will be developed at a later date, all held under Mining Leases. Numerous prospects have been identified warranting detailed exploration to further extend the life of the project.
Brockman Project
The Brockman deposit, near Halls Creek in Western Australia, contains JORC Indicated and Inferred Mineral Resources, estimated using the guidelines of JORC Code (2012 Edition).
The Company is also progressing a Mining Lease application over the Brockman Rare Earths and Rare Metals Project.
Hastings aims to capitalise on the strong demand for critical rare earths created by the expanding demand for new technology products.
