Revolver’s diamond drilling at its Dianne project in Queensland has returned “stunning” results of up to 50% copper minerals, the company says. 

The program intersected visible copper mineralisation in 13 out of 17 holes, with best results of:

  • High-grade chalcocite / chalcopyrite with a visual estimate of up to 50% copper minerals present from 187.2m to 188.4m down hole (Hole 21DDMD05);
  • A 41.88m intercept with a visual estimate of up to 8% copper minerals (Hole 22DDMD07); and
  • An intercept of 58.1m with a visual estimate of up to 4% copper minerals (Hole 22DDMD15).

Potential for high-grade, near-surface copper

The Dianne project includes the historical copper mine that produced 63,758t of copper at an average grade of 22.7% from open cut and underground operations between 1979 and 1983.

And the company is confident there’s potential for economic, near-surface copper at the project.

“We have delivered amazing drill results, with 13 out of 17 holes intersecting substantial copper mineralization,” Revolver Resources (ASX:RRR) MD Pat Williams said.

“This result has clearly expanded the previously known footprint of the copper deposit.

“We have demonstrated that Dianne has the potential for both high-grade massive sulphide and near surface Green Hill mineralisation extracting both with a potential bulk minable style of configuration.”

Assay results expected in Q2

Williams said the company expected to release assay results in the coming weeks and months as RRR progresses towards an initial JORC Mineral Resource Estimate in Q3.

“And in addition to this, Revolver will also be reporting in the near future on the program and progress for its Osprey copper project located in the world class Mt Isa mining province,” he said.

Multiple deposit scale step-out, near pit and district scale IP targets remain to be tested during the planned second drilling campaign for H2 2022.

The company has also scheduled a tenement scale heliborne EM survey for early H2 of 2022 that will expand on district scale geophysical coverage from ground IP survey completed December 20223.
