Havilah Resources reports extension of Birksgate skarn mineralisation

Havilah Resources Limited (ASX: $HAV) has reported extensions to the Birksgate prospect skarn copper-gold-molybdenum mineralisation in the Curnamona Province of northeastern South Australia. The drilling has confirmed the extension of the mineralisation at least 1.5 km east of the original 2014 discovery by the MMG-Havilah joint venture. The mineralised target potentially covers an area of at least 8 km² in a broad synclinal structure.

Executive commentary on Birksgate skarn drilling results

The MMG-Havilah joint venture intersected consistent skarn mineralisation in four diamond drillholes during 2014 and Havilah has now duplicated this in three RC drillholes over 2 km of strike, located roughly 1.5 km to the east, confirming Havilah's conceptual geological model. It is remarkable that all drillholes that intersected the skarn horizon to date have returned appreciable copper-gold-molybdenum mineralisation. Geological reasoning suggests this mineralisation could extend continuously all the way from the western to the eastern limb of the syncline, potentially covering an area of at least 8 km2 in the subsurface. Based on this interpretation, the Birksgate skarn may therefore represent a very large copper-gold-molybdenum mineralised target that warrants systematic follow up drilling to understand the syncline geometry and, if feasible, to define a JORC Mineral Resource. The associated uranium and vanadium approach levels that may potentially be economic to recover with the other metals, depending amongst other things on the metallurgical recovery characteristics. The ubiquitous molybdenum at Birksgate assumes greater significance given the December 2023 update of the Australian Government's critical minerals list that now includes this metal. The 21 metre intersection of 4.9% TGC (total graphitic carbon) mineralisation in the K4 unit over a potentially large area in the centre of the syncline further highlights the multi-commodity discovery potential of the Birksgate prospect area.
