Hillgrove Resources' (ASX:HGO) underground (UG) diamond drilling has continued to extend the continuity of the Spitfire and South West (SW) Kavanagh mineral systems returning outstanding results a its Kanmantoo Mine in South Australia.

Drilling is continuing as part of the stope definition drilling providing input into stope planning and development designs.

Locally, the infill UG drilling demonstrates continuity of mineralisation and has provided some exceptional Cu intersections including:

  • 40m @ 1.38% Cu (uncut) from 74m downhole (23KVUG0238), and
  • 36m @ 1.78% Cu + 0.15g/t Au (uncut) from 175m downhole in Spitfire (23KVUG0101)

“Spitfire was initially considered to be a modest mineral zone which extended over approximately 50m vertically, however the recent drilling confirms that the Spitfire lode is far larger than initially anticipated and now extends more than 250m vertically and remains open at depth,” CEO and Managing Director, Lachlan Wallace, said.

“SW Kavanagh is also looking positive with a number of previously unknown high grade copper breccia zones being identified in the recent 12 hole drilling programme. As development extends and deeper drill platforms are established, we will continue to chase both the Spitfire and SW Kavanagh mineral system at depth.

“The close proximity of the Spitfire and the SW Kavanagh lodes to the current underground decline development provides an opportunity to bring the extensions of these lodes into the mine plan for modest incremental cost.

“The strike rate of 62 intersections of significant Cu-Au mineralisation from only 42 holes is exceptional and reflects the high degree of down dip continuity of the mineral lodes. Given there are there are nine known mineral lodes that remain open at depth on the permitted mining lease, this strike rate positions the company for an exciting future through exploration growth.”
