The Board of Hastings Technology Metals Limited [ASX:HAS] (Hastings or the Company) is pleased to announce further assay results from the infill drilling programme at Bald Hill South within the Yangibana Project. Results continue to support the existing interpretation of the mineralisation and the Company expects to be able to upgrade at least a portion of the current JORC Indicated Resources to the Measured Resource category on completion of the programme.
The drilling programme has been temporarily halted due to heavy rains in the Upper Gascoyne region, with drilling expected to recommence in the coming days.
The Project‐wide aeromagnetic and radiometric survey has been completed and interpretation has commenced with the aim of prioritising targets for follow up and potentially drilling as part of the resource expansion programme that is planned to commence on completion of the infill drilling programme.
A detailed air photo and topographical survey has been completed to expand on the coverage achieved in 2014. This survey covers new potential targets but also provides detailed coverage of potential infrastructure sites, including main access roads from the Shire road to site, to assist site engineering planning.

YANGIBANA PROJECT
Infill Drilling Results
The Company has received assay results from the remaining holes drilled to date as part of the major infill drilling programme to obtain a large composite sample from the Eastern Belt mineralisation at Yangibana. Because of the higher neodymium‐praseodymium (Nd‐Pr) content and the superior metallurgical characteristics of this portion of the overall Yangibana Project compared to the other areas, this Eastern Belt will be the focus of the early development of the Project. Collar data for these holes is provided in Appendix 1.
Best intersections from these holes are:‐

Drill results have confirmed the interpretation of the mineralisation at Bald Hill South and it is expected that at least a portion of the current JORC Indicated Resources will be upgraded to Measured Resource category following the completion of the drilling programme.
TERMINOLOGY USED IN THIS REPORT
TREO is the sum of the oxides of the heavy rare earth elements (HREO) and the light rare earth elements (LREO).
HREO is the sum of the oxides of 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).
CREO is the sum of the oxides of neodymium (Nd), europium (Eu), terbium (Tb), dysprosium (Dy), and yttrium (Y) that were classified by the US Department of Energy in 2011 to be in critical short supply in the foreseeable future.
LREO is the sum of the oxides of the light rare earth elements lanthanum (La), cerium (Ce), praseodymium (Pr), neodymium (Nd), and samarium (Sm).
NEODYMIUM EQUIVALENCE
Hastings is concentrating its efforts on the recovery of four important rare earths – neodymium, praseodymium, dysprosium and europium. To portray the grade of the mineralisation Hastings has established neodymium‐equivalent figures where:‐
The Nd2O3 equivalent (Nd2O3‐Eq) values have been calculated based on the following rare earths prices. These prices have been established by independent consultants Adamas Intelligence in its report entitled “Rare Earth Market Outlook, Update: Supply, Demand and Pricing from 2014 through 2020” dated 30 June 2015, and are being used by Hastings in the evaluation of the project.
