Rumble Resources Limited (ASX: RTR) has commenced a 7,000m air core and reverse circulation drill programme on a series of newly defined battery metals targets within the 100% owned Wardawarra Project, located 100km northeast of Mt Magnet within the Murchison Goldfields of Western Australia.
These exciting new nickel, copper, cobalt, PGE’s, lithium, tantalum and niobium targets were generated from a detailed historic exploration review, regional grab sampling (completed by Rumble), shallow regolith drilling and pulp re-assays from potential nickel bearing rocks at the Cranes Au prospect.
100% Owned Wardawarra and Western Queen Projects – Targets
Based on a detailed historic exploration review and orientation litho-geochemistry (from grab and drilling assays) completed by Rumble, the highly prospective Wardawarra Greenstone Belt (35km strike within Rumble tenure) has been re-interpreted into series of mafic and ultramafic lithological successions.
Of significant interest is the extensive Yinga Ultramafic Sequence (newly named) which has now been interpreted to extend up to 20km in strike (within Rumble tenure) and is up to 2km in width.
Nickel Copper Cobalt PGE Targets – Yinga Ultramafic Sequence
Only two prospects have been partially drill tested within Yinga Ultramafic Sequence Yinga Ni-Cu-Co Prospect – E20/967 Historic drilling (Percussion and Diamond Core) returned:
• 19.8m @ 0.88% Ni, 0.1% Co from 10.7m (PDH16), Including 9.1m @ 1.26% Ni from 19.8m
• 50.3m @ 0.64% Ni from 10.7m (PDH11), Including 4.6m @ 1% Ni from 15.2m
• 39.6m @ 0.63% Ni, 0.08% Co from surface (entire hole PDH05), Including 16.8m @ 0.81% Ni from 6.1m
• 25.9m @ 0.69% Ni from 13.7m (PDH14)
• 22.5m @ 0.69% Ni from 12.5m (DDH1 – part assayed)
• 18.3m @ 0.63% Ni from 4.6m (PDH15)
Cranes Au-Ni-Cu-Co Prospect – M59/208
The Cranes Prospect is situated on the northern boundary of Rumble’s 100% owned M59/208 (Western Queen Gold Project) and is located only three km south of the Yinga Prospect, lying within an attenuated portion of the Yinga Ultramafic Sequence and proximal to the regionally extensive Wardawarra Shear Zone
The Cranes Prospect was originally targeted and assayed for gold by Rumble. Based on elevated Nickel in drill-hole response (routine pXRF analysis) and re-assaying of air core drilling pulps, a small aircore (AC) regolith drilling programme was completed to ascertain the potential for nickel sulphide mineralisation associated with the Yinga Ultramafic Sequence.
Results from re-assaying of pulps (wet lab analysis) include:
• 20m @ 0.54% Ni from 10m (4m Comp) – CRAC037
• 8m @ 0.69% Ni, 0.13% Co from 6m (4m Comp) – CRAC045
• 8m @ 0.80% Ni from 26m (4m Comp) – CRAC046
Rumble completed 58 shallow air core drill holes for 1825 m, and six (6) slimline RC drill holes north and west of the Cranes Au Prospect.
Results (wet lab analysis) from this drilling include:
• 9m @ 0.67% Ni, 0.11% Co from 17m – WWAC024
• 7m @ 0.64% Ni from 15m (includes Cu to 720ppm) – WWAC066
• 9m @ 0.50% Ni, 0.11% Co from 11m (Pt + Pb to 165ppb) – WWRC001
• 7m @ 0.58% Ni from 23m – WWRC004
Lithium-Tantalum-Niobium Targets
E20/967 – Tantalus Pegmatite
The Tantalus Pegmatite is a large weathered shallow east dipping unit with a strike of 600m and is up to 60m wide. Previous exploration focused on alluvial tantalum, niobium and tin. No historic assaying for Li had been completed. Rumble completed a small grab sampling campaign (six grab samples) to ascertain lithium potential. Results include: • Lithium – Li2O to 2% • Rubidium – Rb2O to 1.02% • Caesium – Cs2O to 0.2%
Eastern Gneiss Pegmatite Swarm
The Wardawarra Greenstone Belt is in contact with gneissic granites, ortho and para-amphibolites on the eastern margin.
A large pegmatite swarm intrudes into the “Eastern Gneiss” margin and into the parts of the Wardawarra Greenstone Belt. Reconnaissance exploration has mapped pegmatite outcrop occurrences over some 12km’s of strike. The pegmatites trend generally northwest within a north-northeast trending corridor. Initial grab sampling (60 grab samples) identified microcline dominant sub-vertical multiple pegmatites up to 20m in width with amazonite zones.
The pegmatites returned a strong background in rubidium, with 85% of grab samples returning a 0.5% Rb2O average, along with elevated Cs, Ta and Nb.
One pegmatite cluster returned strong lithium values. Pegmatite geochemistry includes: • Lithium – Li2O to 5.32% • Rubidium – Rb2O to 3.35% (average 5000ppm – Amazonite/Microcline) • Caesium – Cs2O to 0.84%
