INTRODUCTION
Following the success of the Stage 1 drilling programme, Hastings Rare Metals Limited (ASX:HAS) is pleased to announce that it has commenced its Stage 2 drilling programme at the Yangibana Project in the Gascoyne region of Western Australia. Reverse circulation (RC) drilling is under way and diamond drilling is planned to start towards the end of September. A total of 6,500m of drilling is planned.
The target within the Yangibana Project is for rare earths mineralisation associated with ironstone lenses that occur within a large intrusive unit of carbonatite affinity, now termed the Gifford Creek Carbonatite Complex. Eleven such ironstone targets were previously drilled by Hurlston Pty Limited in the 1980s and non-JORC resources were estimated for each. These targets are numbered 1-11 on Figure 1 which shows the outline of the area in which Hastings has interests.
Hastings completed the first JORC resource estimate for the Yangibana Project, based on its Stage 1 drilling programme at the Yangibana North deposit (Prospect 1 in Figure 1,) in July 2014. This resource estimation was undertaken by

Stage 2 drilling aims to define initial resources at each of Bald Hill, Frasers, Lion’s Ear, Hook, Gossan, Kane’s Gossan, and Yangibana South. Further drilling will be undertaken at Yangibana North to expand on the initial resource estimation. Figure 2 shows the locations of these prospects within the Yangibana tenements.

Individual Prospect Reviews
Bald Hill Prospect
Eleven RC holes were drilled at Bald Hill in the 1980s. Results from Bald Hill South included some very high neodymium results. Recent rock chip sampling at Bald Hill (ASX release 17/6/14) provided further encouragement with 19 of 28 samples exceeding 5,000ppm TREO to a maximum of 60,550ppm TREO including 27,120ppm Nd2O3. Of additional interest, six samples returned greater than 5,000ppm Nb2O5 (niobium oxide) to a maximum of 66,010ppm.
Frasers
Seven RC holes were drilled at Frasers prospect in the 1980s returning consistently high neodymium grades including the highest neodymium intersection returned during that programme of 2m at 2.9% Nd2O3.
Lion’s Ear
Ten RC holes were drilled into the Lion’s Ear prospect in the 1980s returning moderate to high TREO grades. Rock chip sampling by Hastings has returned values ranging from 7,700ppm to 128,000ppm TREO from five samples, with the latter sample including 21,900ppm Nd2O3.

Hook
Seventeen RC holes were drilled into the Hook prospect in the 1980s returning variable results with some very high grade zones indicated. Rock chip sampling by Hastings has returned values ranging from 3,400ppm TREO to 35,038ppm TREO from four samples.
Gossan
Three RC holes on one section were drilled in the 1980s at Gossan indicating modest grades and widths. Rock chip samples collected by Hastings averaged 16,728ppm TREO with a highest grade of 36,400ppm TREO including 7,100ppm Nd2O3.
Kane’s Gossan
Kane’s Gossan was tested by six RC holes in the 1980s indicating modest grades over widths to 4m over a long strike length. Five rock chip samples collected by Hastings peaked at 19,166ppm TREO including 3,758ppm Nd2O3.
Yangibana South
Five RC holes were drilled into the Yangibana South target in the 1980s indicating narrow, low grade mineralisation. Rock chip samples collected by Hastings, however, have averaged 14,025ppm TREO with a maximum of 29,200ppm TREO including 14,100ppm Nd2O3.
Yangibana North
Hastings will undertake additional drilling at Yangibana North to extend the current JORC resource to the west and at depth where it appears to be strengthening. This deeper drilling could intersect less oxidised material and provide the first intersections of fresh carbonatite-style mineralisation. An understanding of unaltered deeper mineralisation would provide important insights into the potential of deeper mineralisation at the Yangibana Project as a whole.
Diamond Drilling
Diamond drilling will be carried out within the current resource area at Yangibana North and those prospects that provide positive results during the RC drilling phase. The diamond drilling will provide samples for accurate measurement of specific gravity that directly affects the estimation of resources. The JORC resource estimation for Yangibana North is based on a specific gravity (SG) of 2.8.

Summary
The targets to be tested during Q3/Q4 2014 are all within 100m of surface and most are much shallower.
On completion of the planned drilling programme of around 6,500m, it is expected that an Inferred Resource estimate will be feasible at each prospect. The Inferred Resources are also expected to remain open in all directions.
*** 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).

About Hastings Rare Metals
-
Hastings Rare Metals is a leading Australian rare earths company, with two JORC compliant rare earths projects in Western Australia.
-
The Hastings deposit contains JORC Indicated and Inferred Resources totalling 36.2 million tonnes (comprising 27.1mt Indicated Resources and 9.1mt Inferred Resources) at 0.21% TREO, including 0.18% HREO, plus 0.89% Z r O₂ and 0.35% Nd₂O₅.
-
The Yangibana deposit contains JORC Indicated and Inferred Resources totalling 3.36 million tonnes at 1.34% TREO, including 0.29% of CREO (that includes 0.27% Nd2O3) (comprising 1.86 million tonnes at 1.38% TREO Indicated Resources and 1.50 million tonnes at 1.29% TREO in Inferred Resources).
-
Rare earths are critical to a wide variety of current and new technologies,
-
including smart phones, hybrid cars, wind turbines and energy efficient light bulbs.
-
The Hastings deposit contains predominantly heavy rare earths (85%), such as dysprosium and yttrium, which are substantially more valuable than the more common light rare earths.
-
The Company aims to capitalise on the strong demand for heavy rare earths created by expanding new technologies. It has recently validated the extensive historical work and completed a Scoping Study to confirm the economics of the Project.
