Newcrest Mining’s exploration efforts at the Havieron copper-gold joint venture project in Western Australia continue to produce the goods.
The project, which Newcrest operates alongside Greatland Gold, has delivered another round of high-grade drilling results, with 19 of 24 recent drill holes returning significant mineralisation.
Drilling has been focussed on potential resource growth at the South East Crescent, Northern Breccia and Eastern Breccia zones, with infill drilling at South East Crescent looking to support the potential conversion of inferred to indicated resources.
Some of the findings of Newcrest’s infill drilling at South East Crescent include intercepts of 119.7 metres at 1.2 grams per tonne (g/t) of gold and 0.49 per cent of copper from 1041 metres of drilling, and 164.3 metres at 1.8g/t of gold and 0.53 per cent copper from 1065 metres including 14.3 metres at 9.7g/t of gold and 0.78 per cent copper.
Other high-grade gold hits included a 45.1-metre intercept of 6.7g/t of gold from 919.5 metres and a 14.2-metre intercept at 20g/t of gold from 1036 metres.
Growth drilling at Havieron continues to show potential for resource additions outside of the existing inferred mineral resource limits.
There’s the potential for extension of South East Crescent below the current mineral resource, with recent drilling presenting increasing grade and mineralisation thickness.
Multiple higher-grade targets Northern Breccia and North West Pod also have the potential to be expanded.
At South East Crescent, growth drilling on 75-metre by 75-metre spacing has extended the mineralisation 250 metres below the initial inferred mineral resource estimate.
Four drill holes have returned results from the growth drilling at South East Crescent, including HAD086W3 which returned 44.7 metres at 7.1g/t of gold and 0.17 per cent copper from 1412 metres, including 20.2 metres at 15g/t of gold and 0.29 per cent copper in the recent run.
Newcrest has completed a total of 219,561 metres of drilling from 266 drill holes since commencing exploration activity at Havieron, not including any holes in progress, abandoned holes or drill holes yet to be sampled.
“At Havieron, our exploration is now totally focused on growth which has continued to demonstrate potential for resource additions outside of the existing inferred mineral resource limits,” Newcrest managing director and chief executive officer Sandeep Biswas said.
“We have eight operating rigs exploring the high-grade targets in and around the main Havieron deposit including the high grade depth extents of the South East Crescent.”
