Revolver Resources Holdings Limited (ASX:RRR) has identified 14 compelling EM conductor targets with results from a recently completed airborne geophysical programme over its 100%-owned Osprey Project located in the Mt Isa inlier of north-west Queensland.
A regional Heli-EM survey using the NRG “Xcite” system has defined the high-priority late- time bedrock conductor targets. These are directly analogous to the type of response expected from Mt Isa-style mineralization.
“Osprey has been the sleeping giant of the Revolver portfolio since we listed in 2021. The Mt Isa region is one of the best endowed base metal provinces in the world,” Managing Director, Pat Williams, said.
“The north-western succession of the Mt Isa Inlier under cover is a newly emergent hotspot for mineral exploration targeting large scale Iron Oxide Copper Gold (IOCG) and Mt Isa-style base metal deposits.
“We believe that recent tenement activity around the Osprey Project by resource majors, Fortescue and Anglo American, is further endorsement of the high and large-scale prospectivity of this area.
“The recently completed Heli-EM survey delivers an impressive number of high-priority conductor targets demonstrating typical Mt-Isa type EM characteristics. These targets are now set to be refined, prioritized and pursued via drill testing over the second half of this calendar year. This represents an exciting next phase in the exploration of our highly prospective and 100%-owned Osprey Project.”
Revolver’s Osprey Project covers 765 sq. km over six adjoining EPMs and is located in northwest Queensland, approximately 220km north of Mount Isa. The host geological province is one of the world’s richest mineral producing regions, with world- class producing mines (Zn, Pb, Cu and Ag). The geological setting of the Osprey Project tenure is considered by Revolver to be conducive for Tier-1 deposits of Iron Oxide Copper Gold (ICG) and Mt-Isa Style base metal deposits.
Revolver’s current strategy at Osprey is to rapidly and cost-effectively screen the tenure for new Mt Isa-style (and potential Iron Sulphide Copper Gold systems (ISCG)) targets. The recent Heli-EM survey was flown in order to detect potential massive sulphide mineralization in the immediate 300m below surface for direct drill targeting.
The high-resolution helicopter-borne electromagnetic and magnetic data survey was commissioned through New Resolution Geophysics (NRG) Australia and was undertaken during the second half of 2022. It covered 706 line-kilometres of prospective tenure located within five of the six exploration tenements that comprise the Osprey Project.
Further interpretation and targeting, including overlay of results from historic drilling and ground geophysics programs, is underway. The high-priority target anomalies will undergo further conductivity section modelling and detailed conductor plate modelling of the EM decay data using Maxwell EM modelling software to further assist final drill targeting.
Following this further conductor refinement and prioritization, drill testing of these high-priority targets is expected to commence from June 2023.
