Wardawarra Project

• Targeting Large Scale Magmatic Ni-Cu-Co sulphide deposits
• Targeting Large Scale Li-Ta-Nb-Sn-Cs-Rb-Ree Deposits
• Targeting High-Grade Gold Deposits

Rumbles 100% owned Wardawarra Project consists of one (1) granted exploration license (E20/967) and one (1) exploration license application (ELA59/2443) for a total area of 213.3 km². 

The Wardawarra Project is contiguous to the north and south of Rumbles 100% owned Western Queen Gold Project which consists of two (2) granted mining leases, M59/45 and M59/208, and has a JORC (2012) Mineral Resource Estimate (MRE) of 2.1Mt @ 2.42 g/t Au for 163,000oz. There are a number of operating gold processing facilities in close proximity of the Western Queen Gold Project (see image 1). The closest mill is Gascoyne Resources Limited’s (ASX:GCY) Dalgaranga Mill (48km) which has a capacity of 2.5 Mtpa.

Only two prospects have been partially drill tested within Yinga Ultramafic Sequence (image 2)

Yinga Ni-Cu-Co Prospect – E20/967

Historic drilling defined significant oxide Nickel, Copper and Cobalt at the Yinga prospect 5km north of the Western Queen Gold Project. Intersections include:

• 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)

• Nickel mineralisation defined over 1.8km of strike with three prospective ultramafic horizons with potential for further parallel zones east of the Yinga Prospect

• Historic drilling tested only the shallow oxide-transition zone highlighting significant potential for massive Nickel-Copper-Cobalt sulphides down dip/plunge and along strike

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 3kms’ south of the Yinga Prospect, lying within an attenuated portion of the Yinga Ultramafic Sequence and proximal to the regionally extensive Wardawarra Shear Zone (See image 1 & 2).

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 

Results (wet lab analysis) from Rumble 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

Tantalus Pegmatite

The Tantalus Pegmatite is a large weathered shallow east dipping unit with a strike of 600m and is up to 60m wide (See ASX announcement – Wardawarra Project – Significant Ni, Cu, Co, Au, Ta, Nb, Sn and Li – 10/11/2021). 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 (sixty 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 (see image 1) 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%

Western Queen Gold Deposit(s) – Extension

• The inferred southern extension of the Western Queen Shear Zone extends into the Wardawarra Project (E20/967) under 10 – 15m of cover approximately 1.5km south of the Western Queen South Pit. No drilling has tested the zone.

• The inferred northern extension of the Western Queen Shear Zone has not been drill tested under cover 1km north of the Western Queen Central Pit within M59/208 and into the Wardawarra Project (E20/967).

East Trixie Gold Prospect

• The inferred southern extension of the mineralised Western Queen Shear Zone is interpreted to be associated with a series of historic gold prospects collectively known as East Trixie.

High-Grade Au System

Historic High-Grade gold intercepts showcase the exploration upside along the Western Queen Shear Zone including:

• 4m @ 49.73 g/t Au from 134m (QND-38975-1)
• 5m @ 38.76 g/t Au from 193m – (WQRC188)
• 8m @ 26.27 g/t Au from 14m (WQRC155)
• 7m @ 60.6 g/t Au from 70m – (WQJC-32)
• 6m @ 37.34 g/t Au from 50m – (QNC-10310-1)
• 6.4m @ 36.09 g/t Au from 305.7m (WQD-1072)
• 6m @ 34.24 g/t Au from 354m (WQRC007D)
