Rumble Resources Limited (ASX: RTR) (“Rumble” or “the Company”) is pleased to announce the return of significant high-grade tungsten assays from selected pulp samples of Reverse Circulation (RC) drilling completed by the Company in 2021. The assays confirm a potentially significant tungsten discovery that is spatially associated with the known gold resources at the Western Queen Gold Project.
Highlights
- Tungsten assays received from selected drill pulp samples from seven holes drilled in 2021 have confirmed a potentially significant high-grade tungsten discovery at Western Queen
- Significant assay intersections include:
- 12m @ 0.56% WO3 and 0.46g/t Au from 69m (WQRC032)
- including 2m @ 2.48% WO3 and 0.12g/t Au from 70m
- 3m @ 0.69% WO3 from 90m and 2m @ 1.55% WO3 from 159m (WQRC101)
- 12m @ 0.34% WO3 and 3.22g/t Au from 202m (WQRC178)
- including 7m @ 0.49% WO3 and 4.71g/t Au from 206m
- 2m @ 0.75% WO3 and 0.48g/t Au from 81m (WQRC019)
- 12m @ 0.56% WO3 and 0.46g/t Au from 69m (WQRC032)
- The pulp assays complement the exceptionally high-grade intersection in recently reported drill hole WQDD0131:
- 4.05m @ 4.58% WO3, 0.72 g/t Au from 174.85m; including
- 2.05m @ 8.71% WO3, 1.38 g/t Au from 176.85m; and
- 0.65m @ 18.35% WO3, 2.97 g/t Au from 176.85m
- These new assays are largely coincident with a continuous tungsten anomaly outlined over a 2km area defined from drillhole XRF data and parallel the Western Queen Shear and known high-grade gold mineralisation
- The width and grade tenor of significant tungsten assays received at Western Queen to date suggest that Western Queen could host a significant tungsten resource
- Review of the Company’s pXRF analytical data has shown some 87 reverse circulation (RC) and diamond drill (DD) holes completed by Rumble reported >500ppm W
- The Company now plans to further analyse historical drilling including RC drill pulps and a substantial diamond core library held in storage for tungsten, which will likely constitute the bulk of the data required to classify an initial resource estimate, if one can be determined
- Tungsten is a critical and strategic metal given its relative scarcity, supply risk, defence applications and limited substitution options
Peter Harold, Managing Director and CEO commented“the discovery of tungsten at Western Queen has demonstrated the huge optionality that we have in our extensive tenement portfolio. The assay results from the 2021 drill pulp samples have confirmed that we have made a significant tungsten discovery at Western Queen. This is brilliant work by our exploration team and we look forward to receiving further assays from the substantial amount of existing drill core and pulps. Best case scenario, positive results from this future analysis could allow us to calculate a resource without any additional drilling.
Whilst the tungsten is a great new discovery, we already have substantial gold resources at Western Queen on a granted Mining Leases within trucking distance of a number of mills. Our primary focus is therefore to monetise these resources in the near term.”
Western Queen Tungsten Discovery
Tungsten (W) laboratory assays have been received for selected pulp samples from an initial seven holes of previous RC drilling completed by the Company in 2021 as part of the Western Queen gold resource drill program. The initial seven holes were selected based on appropriate spatial coverage across the 900m strike length of high tenor
>1000ppm W in pXRF (refer Figure 1) and having at least one sample in the hole greater than 5000ppm W in the pXRF database.
Significant intersections from the pulp samples include 12m @ 0.56% WO3, 0.46g/t Au from 69m, with the higher grade section of 2m @ 2.48% WO3 and 0.12g/t Au from 70m in WQRC032, 12m @ 0.34% WO3 and 3.22g/t Au from 202m, with a higher grade section of 7m @ 0.49% WO3 and 4.71g/t Au from 206m in WQRC178, 9m @ 0.22% WO3 plus 0.35g/t Au from 76m with a higher grade section of 2m @ 0.75% WO3 and 0.48g/t Au from 81m in WQRC178 and 5m @ 0.31% WO3, 0.31g/t Au from 220m in WQRC176( refer to Figure 1 and Table 1).
The significant intersections from the seven holes of pulp samples complement the previously reported tungsten mineralisation within drillhole WQDD013 (Refer to Rumble Resources Limited ASX announcement High-grade Tungsten Discovery at Western Queen 6 August 2024) which returned a spectacular intersection of 4.05m @ 4.58% WO3, 0.72 g/t Au from 174.85m; including 2.05m @ 8.71% WO3, 1.38 g/t Au from 176.85m; including 0.65m @ 18.35% WO3, 2.97 g/t Au from 176.85m(refer to Figure 2).
Figure 1 - Western Queen Project – Plan highlighting contoured maximum pXRF W in drill holes and location and intercepts of significant W intersections from pulp samples and WQDD013.
Encouragingly, all seven holes of pulps samples returned significant intercepts grading greater than 0.1% WO3. While geological investigations are preliminary, the tungsten mineralisation contains large aggregates of scheelite grains (up to 5mm) occurring parallel to the main foliation trend. The mineralisation is essentially multiple scheelite-pyroxene (tremolite)+/-gold endoskarn zones associated with the Western Queen orogenic shear zone (host to gold mineralisation) within dominant Archaean mafic amphibolite lithologies. Tungsten mineralisation occurs spatially proximal to gold mineralisation, however high-grade tungsten mineralisation does not always corelate with high-grade gold mineralisation The skarn development is thought to have been a later stage to the main gold event at Western Queen.

High grade Massive Sulphide Intercepts Confirmed at Oval
HIGHLIGHTS:
- OVD027 confirms the continution of high grade massive sulphide from OVD0211 with an intercept of 6.1 metres of 4.16% Cu, 3.51% Ni, 0.G3g/t E3, and 0.13% Co from G8.2 metres encountered between broader high grade zones of:
- A dense disseminated intercept - 26.2 metres of 0.44% Cu, 0.52% Ni, 0.12g/t E3, and 0.03% Co from 72.0 metres and
- A net textured intercept - 15.3 metres of 1.15% Cu, 0.79% Ni, 0.35g/t E3, and 0.04% Co from 104.3 metres;
- A high grade broad intersection is confirmed at the central part of the Oval area by OVD026. It includes a massive sulphide intercept in hole OVD026 of 1.8 metres of 3.21% Cu, 3.32% Ni, 0.6Gg/t E3, and 0.14% Co from 105.0 metres within broader mineralisation of:
- 19.8 metres of 1.23% Cu, 0.98% Ni, 0.36g/t E3, and 0.05% Co from 91.2 metres.
OVD026 is located 100 metres northwest of the previously announced 8.8 metres of massive sulphide identified in drillhole OVD021.
On completion of the Phase 2 exploration work and receipt of all assays, Managing Director Gan-Ochir Zunduisuren, commented:“The 2024 Phase 1 and 2 drilling and exploration programs have confirmed the broad presence of high-grade mineralisation in the Oval gabbroic intrusion. The grades intercepted in some of the drillholes are exceptional and may be indicative of broader potential over a larger area, given Oval is a greenfields discovery.
The 2025 exploration program will focus on obtaining information on the size/metal content potential of the Oval Cu-Ni-PGE mineral system as well as targeting the possible deeper magmatic sources at Oval. Broader exploration is also planned at potential extensions of Oval and nearby look-a-like prospects. We look forward to updating shareholders on progress, with drilling expected to commence in around 8 weeks”.
Summary of Phase 2 exploration drilling at Oval Cu-Ni-PGE project
The Company’s recent drilling work has predominantly focused on finding high-grade mineralisation in the olivine-amphibole gabbro at the Oval project. The multiple intercepts of massive sulphide mineralisation with different ratios of metal contents throughout the Oval gabbroic intrusion is highly encouraging for the presence of one or more deeper sources of high grade mineralisation in the opinion of ABM.

Drillhole OVD02c
Drillhole OVD026 was designed to test the Down-Hole Electromagnetic (DHEM) conductor plate identified as OVD007_L2_B (reinterpretation of OVD007_L2_A2 by Southern Geoscience Consultants), which exhibits a conductance of 1,000 siemens. The drilling intersected a total of 1G.8 metres of mineralisation with 1.23% Cu, 0.G8% Ni, 0.36g/t E3, and 0.05% Co from G1.2 metres including;
- 4.8 metres of @ 0.45% Cu, 0.43% of Ni, 0.14g/t E3, and 0.02% Co of dense disseminated mineralised gabbro from 91.2 metres,
- 6.6 metres of @ 1.56% Cu, 0.G0% Ni, 0.50g/t E3, and 0.04% Co of net textured mineralisation from G6.0 metres,
- 2.4 metres of @ 1.52% Cu, 1.3G% Ni, 0.43g/t E3, and 0.07% Co of semi massive sulphide mineralisation from 102.6 metres,
- 1.8 metres of @ 3.21% Cu, 3.32% Ni, 0.6Gg/t E3, and 0.14% Co of massive sulphide mineralisation from 105.0 metres, and
- 4.2 metres of @ 0.57% Cu, 0.45% of Ni, 0.21g/t E3, and 0.02% Co of dense disseminated mineralised gabbro from 106.9 metres (Table 1 provides a detailed breakdown of mineralisation intervals).
OVD026 is located in the Oval area, which is approximately 100 metres northwest of the previous intersection identified in drillhole OVD0213. This intercept may represent an extension of the known massive sulphide mineralisation in the Oval area and highlights the potential for further expansion of massive sulphide zones within the broader prospect area (Figures 1 and 3).
