Hastings has established a significant tenement package covering approximately 650 sq km under the Yangibana Project. The Project is centred approximately 270km east-northeast of Carnarvon on Wanna Station in the Gascoyne region of Western Australia (Figure 1) and is best accessed via Gascoyne Junction.

The Yangibana Project hosts extensive rare earths-bearing ferrocarbonatite/ironstone veins that have been evaluated by drilling in the 1980s and by Hastings in 2014 and 2015. The Project also has the potential to host larger, carbonatite-hosted rare earths mineralisation at depth but this target is yet to be assessed.

Hastings efforts to-date have concentrated on the ferrocarbonatite/ironstone-hosted mineralisation. Results have shown that the rare earths mineralisation is enriched in rare earths that are utilised in the high value and growing rare earths magnet sector, being neodymium, praseodymium and dysprosium.

Following a successful drilling programme as part of the Company’s ongoing Pre-Feasibility study, an updated JORC resource estimate will be released in the near future.

Yangibana JORC Resource



Yangibana JORC Resources

Hastings has completed six drilling programmes at the Yangibana Project, testing a number of targets throughout its major tenement holding.

On this basis of this drilling a JORC Resource estimation has been completed by independent consultant Lynn Widenbar and Associates Pty Limited and this was reported in October 2017.

The current total diluted resources for the Yangibana Project are:-

These resources occur in a number of deposits as shown in the diagram below.

 

Yangi Nov 17

The resources are based on a 0.2% neodymium oxide plus praseodymium oxide (Nd2O3+Pr6O11) cut-off, both down hole and in the block models.  They incorporate dilution based on a 0.5m skin beyond the footwall and hangingwall to the mineralisation, at grade.  Average dilution over the total resource is 30%.

There are mineralogical differences between deposits categorised as Western Belt-Style and those categorised as Eastern Belt-Style, see the diagram above.  Eastern Belt-Style deposits host minerals that contain higher proportions of the Company’s main target rare earths, neodymium and praseodymium.

The Total Resource comprises the following deposits split between Eastern Belt-Style and Western Belt-Style and by Hastings interest in the deposit.

Eastern Belt-Style – Hastings 100%

The following deposits are within the Eastern Belt and are held 100% by Hastings.

Yangibana Project Status

The Yangibana Project is advancing towards the completion of a Definitive Feasibility Study (DFS) expected Q42017.  Independent consultants Wave International are providing support for the Company by managing this process.

Current JORC resources total 20.5 million tonnes at 1.18% Total Rare Earths Oxides (TREO) comprising Measured Resources of 3.8 million tonnes at 1.18% TREO, Indicated Resources of 8.2 million tonnes at 1.27% TREO and Inferred Resources of 8.5 million tonnes at 1.11% TREO), including 0.4% Nd2O3+Pr6O11.  

Based on operational and commodity price parameters established by the Company, mining consultants will undertake pit optimisation studies and establish the first reserves for the Project.  Preliminary mining studies indicate potential profitability even at current low commodity prices.

Metallurgical testwork has continued to produce excellent results from both beneficiation and hydrometallurgical sectors and the Company has successfully completed pilot plant tests.  Further improvements have been achieved after the completion of the pilot plant operation and these will be incorporated in the DFS.

Process design is being undertaken by the Company’s consulting engineering company.

All studies are well advanced regarding geotechnical conditions, environmental studies, and groundwater studies sourcing supply for the planned operation.

The Company has signed three MOU (Memorandum of Understanding) offtake agreements, with Qiandong Rare Earths, China Rare Earth Holdings, and Baotou Sky Rock Rare Earth, to sell a total of 6,000 tonnes of Mixed Rare Earth Carbonate (MREC) per annum. The parties have undertaken to negotiate in good faith to reach an agreement for a commercial offtake contract within 12 months from the date of the MOU, and acknowledge that any commercial offtake agreement is contingent on Hastings starting operations and production of MREC from the Yangibana mine.

Yangibana Geology

The dominant lithologies in the tenement area are granites of the Durlacher Supersuite. Rafts of older sedimentary rocks occur within these intrusives.
