Revolver’s latest results from Downhole Electromagnetic (DHEM) and Fixed-Loop EM (FLEM) surveys at it’s Dianne Copper Project have picked up an ‘exciting new anomaly’ which the company says bears an identical conductive response to the famously (drill-validated) very high-grade massive sulphide copper lens near surface.

Aussie-listed Revolver Resources (ASX:RRR) says the team has identified a major new and potentially significant EM anomaly directly below the existing high-grade massive sulphide copper ore body at its Hodgkinson Province Dianne Copper Project in Far North Queensland.

Much more to Dianne

Having just nailed its Phase 1 drill program at Dianne, where diamond drilling assays hit grades of up to 19.8% copper, Revolver now has both clarity and confirmation of the geology and geochemistry of the shallower mineralisation, opening up both the Dianne Massive Sulphide lens and the adjoining wider Green Hill.

The recently completed nine-hole down-hole (DHEM) and seven-line Fixed Loop Electromagnetic Survey (FLEM) both airborne and surface electromagnetic program around the existing Dianne pit has confirmed the potential of the deeper conductive anomaly.

The combined DHEM and FLEM geophysical modelling provides confirmation of the limits and depth extent of the known Dianne Massive Sulphide lens in the near surface zone which has been comprehensively drill-tested and validated.

Modern tools exposing more of Dianne’s secrets   

Revolver managing director Pat Williams says it is now just a question of prioritising further specialist ground-based geophysics work to better define the depth and form of the anomaly.

“The Dianne Copper Project – with multiple phases of systematic, modern exploration – is yielding remarkable results,” Williams said.

“As well as commencing a more dedicated regional program of work, we continue to examine around the existing Dianne pit and the associated trending structures for upside potential.”

He says RRR has been building on the geological knowledge by adding incremental state-of-the-art exploration activities.

“The recent combined downhole and surface electromagnetic program completed around the Dianne pit has revealed very exciting responses from the conductive anomaly, showing an identical conductive response to the known Dianne Massive Sulphide lens we know exists at shallower depths.”

Getting to know Dianne

With a near-term focus on copper, RRR’s 100%-owned Dianne Project was previously one of the highest-grade operating copper mines in the world, producing 63,758 tonnes of direct shipped ore with an average grade of 22.7% copper (1979 -83).

Located in North Queensland’s polymetallic Hodgkinson Province, this massive sulphide project sits on granted mining leases and has undergone very little modern, systematic exploration. Substantial surface geology, IP geophysics and diamond drilling programs have already been completed, with outstanding results.

“We are responding to these results by prioritising additional new work now with a view to defining priority drill targets into this anomaly in the next round of drilling due to commence in coming months.”

Revolver has now fully scaled-up near pit and step-out exploration activities during this 2022 field season.

Next stage work (below) is either already underway or planned in coming months.

What’s top of the new work list at Dianne?

  • Additional surface EM Survey follow up for new deeper conductive anomaly – August 2022.
  • Alteration interpretation and targeting of Worldview 3 satellite imagery – underway.
  • Tenement scale Heliborne EM Survey – planned July/August 2022.
  • Regional reconnaissance follow-up of alteration targets and Heli EM anomalies Q3 2022.
