Yangibana JORC Resource


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

On the basis of this drilling, a JORC resource estimation was completed by independent consultant Lynn Widenbar and Associates and reported in January 2017.

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

These resources occur in a number of deposits as shown in Figure 5.  They incorporate dilution based on 0.5m beyond both the footwall and the hangingwall to the mineralisation, at grade.  Average dilution over the total resources is 30%.

The total resources comprise the following deposits that are being assessed as future mining areas during the Definitive Feasibility Study process.  As such, they are the initial targets for further drilling in 2017.

Eastern Belt – 100% Hastings

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