Introduction
The Directors of Hastings Technology Metals Limited (ASX:HAS) are pleased to announce a 6.7% increase in Measured plus Indicated Resources at the Yangibana Project compared to the most recent JORC Mineral Resource estimate in November 2017 ( ASX release titled “Final 2017 JORC Resource Update including Auer and Auer North Results” 22[nd] November 2017 ). Measured plus Indicated Resources now stand at 13.38 million tonnes within a total resource of 21.67 million tonnes. The total resource now hosts more than 80,000 tonnes of neodymium and praseodymium oxide, the Company’s main economic driver.

An updated JORC Mineral Resource estimation has been completed by independent consultant Lynn Widenbar and Associates incorporating the recent drilling results from Bald Hill, Fraser’s, Auer and Auer North deposits. The total resources as at October 2018 are as shown in Table 1. Note that in all resource tables rounding errors may appear. The resources are based on a 0.2%Nd2O3+Pr6O11 cut-off, with a minimum width of 1.0m. 0.5m of dilution at grade from both the hangingwall and the footwall is incorporated into the estimation.

These figures represent a modest increase in total tonnes compared to the previous estimate from 20,996,000 (+3.2%), but a significant increase in Measured plus Indicated Resources (+6.7%), particularly in the Measured category that has increased by 21.1%.
Resources from the deposits that are planned for early development – Bald Hill and Fraser’s – are shown in Tables 2 and 3. Both deposits are within granted Mining Leases held 100% by Hastings.

About Hastings Technology Metals
Yangibana Project
Hastings Technology Metals (ASX:HAS, the Company) is advancing the Yangibana Rare Earths Project towards production following the completion of a positive Definitive Feasibility Study in November 2017. The Yangibana Project hosts rare earths deposits rich in neodymium and praseodymium, elements vital to permanent magnets that provide many critical components of wide-ranging high-tech products, including electric vehicles, renewable energy wind turbines, robotics, medical applications and others. The Company aims to be the next significant producer of neodymium and praseodymium outside of China.
The established Yangibana reserves and resources are predominantly within tenements held 100% by Hastings, with the majority in granted Mining Leases. Lesser resources are held in a joint venture in which Hastings holds a 70% interest and has management control.
The November 2017 Yangibana Project DFS established JORC Probable Ore Reserves of 5.15 million tonnes at 1.12% total rare earths oxides (TREO) including 0.41% neodymium and praseodymium oxides (Nd2O3+Pr6O11). This Ore Reserve was the basis of the initial operation at a planned production rate of up to 15,000 tonnes per annum (tpa.) MREC including 3,400 tpa. of Nd2O3+Pr6O11. The July 2018 Yangibana Probable Ore Reserve has increased to 7.74 million tonnes at 1.13%TREO including 0.43%Nd2O3+Pr6O11. The increase in Probable Ore Reserves is demonstrated by additional Pre-Feasibility Study work that supports extension of production over the full eight-year period considered in the Company’s November 2017 DFS.
Including the above Ore Reserves, the Company has JORC Measured, Indicated and Inferred Mineral Resources of 21.7 million tonnes at 1.17% TREO including 0.37%Nd2O3+Pr6O11.
Many more areas of the Company’s deposits have the potential for additional resources and exploration programmes are in place to evaluate these areas in future plus the numerous other targets identified to date.
Brockman Project
The Company is also progressing a Mining Lease application over the Brockman Rare Earths and Rare Metals 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, totalling 41.4 million tonnes (comprising 32.3 million tonnes Indicated Mineral Resources and 9.1 million tonnes Inferred Mineral Resources) at 0.21% TREO, including 0.18% HREO, plus 0.36% Nb₂O₅ and 0.90% ZrO₂.
The Company aims to capitalise on the strong demand for critical rare earths created by the expanding demand for new technology products.
