ASX ANNOUNCEMENT | 21 March 2022 |
Russells Copper-Nickel Project
VTEM survey identifies conductors and high priority
copper - nickel drill targets
DRILLING SCHEDULED TO START IN JUNE 2022 QUARTER
- Airborne VTEM survey has identified 32 conductors and upgraded the prospectivity of several target areas for copper-nickel mineralisation
- High impact drilling program will test priority EM conductors and geochemical targets, including a zone of strong rockchip anomalism of up to 29.9% copper at Russells Gossan (ASX BAT 22 June 2021)
- Drill targets include Olympio, which is a discrete conductor coincident with a structurally thickened portion of the prospective target stratigraphy
- Drilling is scheduled to commence following heritage clearance work in April-May 2022
Battery Minerals Limited (ASX: BAT) ("Battery Minerals" or "the Company") is pleased to announce the results of a VTEM survey at its Russells Copper-Nickel Project in WA's East Kimberley.
The final data and report for the high resolution, airborne electromagnetic survey, identifies several modelled bedrock conductors considered prospective for copper ± nickel mineralisation.
Upcoming drilling will test priority VTEM conductor targets along with areas of widespread surface copper anomalism, including up to 29.9% in rock chips at Russells Gossan (ASX BAT 22 June 2021).

DRILLING PROGRAM IN JUNE 2022 QUARTER
The drilling program has been designed to test priority copper ± nickel targets, comprising 6 diamond holes for 1,170m. Several contingency drill sites will also be prepared to allow for flexibility in the drilling schedule based on ongoing results.
Target areas include:
- Olympio Target: characterised by a discrete zone of conductivity (650m long at 100m depth) coincident with a concealed, likely structurally thickened portion of the prospective Azura copper trend stratigraphy
- Azura East Target: defined by a discrete conductive VTEM anomaly, partly concealed and along strike from the prospective Azura copper trend stratigraphy
- Azura North Target: located within the prospective Azura copper trend, defined by an approximately 120m wide zone of anomalous copper at surface with rockchip samples up to 9.7% Cu (ASX BAT 22 June 2021)
- Russell's Gossan Target: defined by a widespread zone of strong surface copper anomalism, including up to 29.9% in rock chips (ASX BAT 22 June 2021)
- Trem Jones Target: lies west of the main Halls Creek Fault and characterised by a zone of conductivity (>1,000m long at 100m depth) along strike from nickel and copper occurrences

AIRBORNE EM SURVEYING (VTEM)
The geophysical survey was flown by Geotech Australia utilizing the VTEM™ Max Time Domain EM system and comprised 510-line kilometres along NW-SE orientated, 100m spaced lines. Resource Potentials Pty Ltd provided geophysical consulting services, including data inversions and interpretation, which is summarised below.
A total of 109 EM anomaly profile picks were manually identified across the Russel's Copper VTEM survey area, of which 23 are rank-1, 22 are rank-2, and 64 are rank-3. All available geophysical, geological, geochemical were reviewed with the VTEM EM profile picks to identify, outline and prioritise VTEM EM target areas of interest on a scale of 1-3. A total of 32 VTEM target areas were identified and prioritised over the area, including 6 priority-1, 9 priority-2 and 17 priority-3 VTEM target areas.

RUSSELLS COPPER-NICKEL PROJECT: (E80/4944, E80/5116, E80/5347, E80/5348, BAT 100%)
The Russells Copper-Nickel Project comprises three granted exploration licences (E80/4944, E80/5116, E80/5347) and one application (E80/5348), covering 258km2 of the Halls Creek Mobile Zone within the East Kimberley region of Western Australia.
The area includes widespread zones of strong surface copper anomalism, up to 29.9% in rock chips at Russells Gossan (ASX BAT 22 June 2021), with the company currently planning a high impact drilling program testing priority targets.
Historic exploration data indicates potential for Michigan-style(basalt-host) and sediment-hosted copper within the Red Rock and Olympio Formations in the project area (ASX BAT 22 June 2021). Several VTEM targets occur within structurally thickened zones of the target stratigraphy and are considered high quality discovery opportunities. In addition, upcoming drilling will also test magmatic nickel-copper-cobalt-PGE targets west of the Halls Creek Fault, in a rock package host to the operating Savannah Ni-Cu-Co Mine (PAN:ASX).
