95% Recovery of Ore And 52% Improvement in Head Grade From Bulk Ore Sorting Trial
- 95.1% recovery of contained Nd2O3+Pr6O11 on 1.8 tonne sorted bulk sample.
- 52% increase in head grade from 0.71% to 1.08% Nd2O3+Pr6O11.
- 37.1% of the sample mass rejected from ore sorting testwork.
- Standard commercial ore sorting technology, X-Ray transmission (XRT), has proven to be extremely effective at removing dilution on samples used in the testing program.
- Technical and engineering programs will continue to investigate the operating scenarios where benefits can be realised for the project.
Hastings Technology Metals Limited (ASX: HAS) (“Hastings” or “the Company”) is pleased to announce successful completion of bulk sample testing through an ore sorting circuit. These outstanding results confirm earlier results from smaller drill core derived samples, which were tested with two different ore sorter vendors.
Previous small-scale test work has shown that off-the-shelf x-ray transmission (XRT) ore sorting technology could be applied to separate out a barren waste stream from the ore. This presents an opportunity to remove waste dilution material from the mining process before the material is fed into the processing plant, potentially resulting in energy and reagent savings in the beneficiation circuit.
The crushed bulk ore sample of 1.8 tonnes was screened into two size fractions -10.5mm and +10.5mm. The sortable fraction (+10.5mm) after being diluted with waste material at either 35% or 60% proportions was screened on a Tomra commercial sorter using XRT technology at 32 tonnes per hour feed rate.
In the base case sorted ore sample, crushed and screened to +10.5mm and diluted with 35% waste material, a total of 37.1% of the sample mass was rejected at a grade of 0.09% Nd2O3+Pr6O11, representing a loss of Nd2O3+Pr6O11 of just 4.9% or an overall recovery of 95.1% Nd2O3+Pr6O11 in the Ore. A corresponding 52% increase or upgrade in the ore head grade was achieved from 0.71% to 1.08% Nd2O3+Pr6O11.
In the sorted sample diluted with 60% waste material, the ore sorting test work program achieved an upgrade factor of 2.16 taking the feed grade from 0.43% Nd2O3+Pr6O11 to 0.93% Nd2O3+Pr6O11, whilst recovering 90.6% of the Nd2O3+Pr6O11.
The sorting tests of the sortable fraction showed that the standard commercial Tomra technology was able to successfully sort the Yangibana ore using XRT technology.
Andrew Reid, Hastings Chief Operating Officer, said “the Yangibana orebody continues to amaze us. Not only with its world-class ratios of Nd2O3+Pr6O11, but now these results have confirmed that ore sorting presents a real and future prospect to gain higher operational efficiencies from the Yangibana Processing Plant”
Detailed quantitative mineralogy is pending on the ore sorting waste stream. However, the results indicate that the REO rejected in the ore sorter waste stream is not composed heavily with liberated monazite, but rather with low-grade REO intergrowths which would not be recovered in the flotation process. The benefit for the Yangibana project is in removing this barren gangue early in the process flowsheet, with potential benefits gained in streamlining the efficiency of the beneficiation plant.
The full opportunity for including ore sorting technology into the Yangibana process flowsheet is still being assessed. Based on these testwork results, technical and engineering programs will continue to investigate the benefits that can be realised across the project.

- Increase in Neodymium and Praseodymium Oxide (Nd2O3+Pr6O11) of 4,800t or 11% to 49Kt, the key components for Electric Vehicle permanent magnets.
- Increase in Total Rare Earths Oxide (TREO) of 11,900t or 9% to 138Kt.
- Updated Ore Reserve extends mine life by 2 years, supporting a 13-year operational life for the Project.
- Probable Ore Reserve tonnes increased 18% to 12.20 million tonnes at 1.13%TREO including 0.40%Nd2O3+Pr6O11.
- Project NPV increased by 6% to A$549 million confirming outstanding project economics.
The Directors of Hastings Technology Metals Limited (ASX:HAS) are pleased to announce an increase in the Probable Ore Reserves at the Yangibana Project in the Gascoyne region of Western Australia. Total Probable Ore Reserves have increased to 12.20 million tonnes at 1.13%TREO including 0.40%Nd2O3+Pr6O11, an 18% increase in ore reserve tonnes compared to the previously announced ASX release entitled “Reserves Increase by 34% to 10.35MT covering 10 Years Operation at Yangibana Project” dated 29 January 2019.
Charles Lew, Hastings Executive Chairman, said “with this increase in mining reserves and corresponding mine life, Hastings has one of the most exciting rare earths projects amongst our peers which has been strategically and purposefully developed over the last few years. Importantly the work completed during 2019 has significantly de-risked the project thereby delivering a high degree of confidence in our mine scheduling and future production.”

The Directors of Hastings Technology Metals Limited (ASX: HAS) are pleased to announce a 13% increase in Measured plus Indicated Mineral Resources (for those deposits forming the basis of the Definitive Feasibility released in November 2017) compared to the most recently announced Mineral Resource estimate in November 2018 (ASX announcement titled “INCREASE IN MEASURED AND INDICATED RESOURCES AT YANGIBANA PROJECT” 28 November 2018). Measured plus Indicated Mineral Resources now stand at 15.1Mt within a total Mineral Resource of 21.3Mt. The total updated Measured and Indicated Mineral Resource now hosts approximately 60Kt of neodymium and praseodymium oxide, an increase of 7%, which forms the basis of the Company’s main economic driver.
Charles Lew, Hastings Executive Chairman, said “we are extremely pleased that this work has not only confirmed our existing Mineral Resources but has significantly increased the Measured and Indicated portions which drive Mining Reserves. We are confident that the expected increase in Ore Reserve will extend the mine life which underpins the project financing.”
