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.
