Revolver Resources (ASX: RRR) has identified multiple priority alteration and iron oxide targets following the processing of WorldView-3 (WV3) satellite data acquired for the Dianne copper project in Far North Queensland’s Hodgkinson Province.
WV3 is a leading-edge technology which collects high-resolution spectral data that can be processed to map the distribution of minerals and iron oxides when identifying outcropping alteration patterns and gossanous zones in hydrothermal systems.
The data was processed to produce a high-resolution, tenement-wide image suite for use as a geological mapping base to better define folded stratigraphy and fault patterns that control the Dianne mineralisation.
Alteration processing of Revolver’s data by consultant Global Ore Discovery highlighted multiple anomalies which have become a priority for immediate follow-up through mapping, rock chip and soil sampling.
Revolver has now initiated a helicopter-borne electromagnetic (Heli-EM) survey by New Resolution Geophysics covering 95 square kilometres — or more than 80% — of the Dianne tenement.
Additional anomalies identified from the survey will also be followed-up as priority targets.
Revolver managing director Pat Williams said the company remains committed to using modern exploration techniques to identify potential upside around the Dianne pit and across the wider tenement package.
“We are very pleased to see multiple phases of systematic, modern exploration at Dianne yielding remarkable results,” he said.
“We are building a comprehensive picture of the geology and mineralisation potential of this very exciting project using state-of-the-art techniques to assess the full extent of the large area.”
Mr Williams said results from the tenement-scale activities will contribute to an upcoming drill program for Dianne before year end.
The historic Dianne project sits in Queensland’s polymetallic Hodgkinson Province and previously yielded grades of more than 22% copper when it was operated between 1979 and 1983.
The project was an open cut and underground operation and Revolver says much of the massive sulphide copper lens orebody remains to be exploited.
In addition to copper, Revolver has identified zinc, silver, gold and cobalt at Dianne.
