Rumble Resources Limited (ASX: RTR) (“Rumble” or “the Company”) is pleased to announce the discovery of high- grade tungsten from diamond core drilling at the Western Queen South deposit. Systematic pXRF analysis of drill hole WQDD013 led to ultraviolet scanning which highlighted very significant zones of scheelite. Wet analysis of the main visible scheelite zone has confirmed the discovery as very high-grade tungsten skarn style mineralisation.
Highlights
- Recent diamond drilling has discovered exceptionally high-grade tungsten (scheelite) mineralisation within the Western Queen gold system
- Drill-hole WQDD013 returned:
- 4m @ 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
- Strong continuous tungsten anomaly outlined over 2km from drillhole XRF data parallels the Western Queen Shear and known high-grade gold mineralisation
- Tungsten occurs at surface between the Western Queen South and Western Queen Central open pits with widths up to 20 metres
- Follow up wet assays for tungsten of selected pulps from RC drilling which formed part of the 2021 mineral resource estimate at Western Queen have been submitted and will be reported when available
- Tungsten is considered a critical and strategic material in world economies due to its economic importance, supply risk and limited substitution options
In addition to the assaying, ultraviolet scanning of the diamond core from WQDD013 has highlighted scheelite within altered mafic. The mineralisation is essentially scheelite-pyroxene +/- magnetite+/-gold skarn zones 2.1Mt @ 2.42 g/t Au for 163,200oz 1
Figure 1 shows the white-blue fluorescence characteristic of scheelite under ultraviolet light. Mineralisation comprises of massive aggregates of white (visible light) grains (up to 5mm) of scheelite paralleling the dominant foliation within the shear zone.

Of great significance is the subsequent review of all of the pXRF data routinely collected by Rumble which has shown tungsten is widespread within the Western Queen gold mineralising system.
Peter Harold, Managing Director and CEO commented“the discovery of the very high-grade tungsten at Western Queen is an unexpected bonus for us from the recent drilling which was targeting extensions to the high-grade gold lodes. While it is very early days the grades of the intersections are exceptional and well above the grades of other tungsten resources globally. We are now waiting with trepidation for the results from the 2021 drill pulps. This discovery shows the huge optionality of the Rumble tenements and the ability of our highly experienced exploration team to make new discoveries.”
Western Queen Tungsten Discovery
Tungsten mineralisation within drill hole WQDD013 (refer to Table 1) returned a spectacular intersection that included:
- 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.
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)+/-magnetite+/-gold exoskarn zones associated with the Western Queen orogenic shear zone (host to gold mineralisation) within dominant Archaean mafic amphibolite lithologies. The skarn development is thought to have been a later stage to the main gold event at Western Queen.
All previous drill holes completed by Rumble as part of the 2021 Western Queen gold resource estimate (2.1Mt @ 2.42 g/t Au for 163,200oz*) have subsequently been analysed for tungsten (W) by pXRF. Review of the pXRF analytical data has shown some 87 reverse circulation (RC) and diamond drill (DD) holes completed by Rumble have reported >500ppm W. Analytical results from pXRF analysers are indicative and may not reflect the true tungsten (W) grade.
Contouring of the pXRF tungsten (W) drill hole results has highlighted the following (refer to Figure 3):
- Very strong tungsten continuity over 2km (>100ppm W contour) with the same strike direction, orientation and position as the Western Queen Shear Zone which hosts the Western Queen gold deposits; and
- Between the Western Queen Central and Western Queen South open pits, the tenor of tungsten increases significantly with some 900m of strike >1000ppm W.
Additionally, a number of drill holes were strongly anomalous in tungsten (W) near surface within oxidised material
Next Steps
Re-assaying of select pulps from the previous Rumble gold resource drilling programs based on the pXRF tungsten analyses is underway to ascertain the spatial variability and tenor of the scheelite mineralisation. Up to 250 pulps from selected RC and diamond holes drilled by Rumble will initially be collected and submitted for wet analysis utilising complete digest through fusion XRF.

Airborne VTEM commences at Ti-Tree Project
- The VTEM Max survey over Cu-Ni-PGE, Broken Hill Style and Uranium targets has commenced.
- The survey is covering:
- The Money Intrusion, prospective for Cu-Ni-PGE mineralisation.
- Copper Ridge and Nick’s Bore over anomalous Copper Drilling results.
- The Coo Creek prospect where drilling by Augustus in 2023 identified strongly anomalous Zn-Pb-Ag mineralisation of possible Broken Hill Style massive sulphide.
- The Munaballya Well area which shows potential for economic uranium mineralisation.
- The surveys will help to advance the untapped potential of the Ti-Tree project to host economic mineralisation of multiple commodities.
VTEM
UTS Geophysics is conducting the helicopter borne VTEM Max survey comprising 646-line km over three separate survey areas. The system is excellent for locating discrete conductive anomalies as well as mapping lateral and vertical variations in resistivity which helps map structure, alteration and rock type. The system also collects magnetic data through a caesium magnetometer.
Figure 1 Prospects and VTEM Survey areas
Money Intrusion
The Money Intrusion, which has proven potential to host Ni-Cu-Co-PGE (platinum group elements), is part of the regional Mundine Well Dolerite Suite, a regionally extensive dolerite (strike length >80km). Mapping, aeromagnetics and multi-spectral imagery show that the Money Intrusion within the Ti-Tree Project covers a strike length greater than 16km, reaching widths >600m in the north (Figure 2).
The VTEM Max system will look to identify conductive anomalies which may reflect concentrations of massive to semi-massive sulphide along the thicker parts of the Money Intrusion within AUG tenure.

Allup Acquires 100% of McLaren Valuable Heavy Mineral Sands Project, West Eucla Basin, WA and Conducts Placement
Highlights
- Advanced Valuable Heavy Mineral Sands (VHMS) project in WA has an indicated and inferred JORC Resource (2012) of 280Mt @ 4.8% Heavy Mineral near surface
- Project comprises 333 sq km of tenements, 150km east of Norseman in the mining-friendly jurisdiction of Western Australia.
- Potential for expanded MRE by including results not in current resource extended, plus extended mine life through additional drilling.
- Ilmenite, a key titanium mineral, is priced well above international silica and kaolin prices at more than US$300/t1 due to increasing titanium shortages.
- Strong ilmenite market demand expected to continue due to supply deficits and mine closures in Kenya, South Africa, and Mozambique
- Allup plans to focus on a lower-cost Capex design to fast-track mine development and produce a bulk concentrate.
- Allup will advance PFS and BFS for McLaren with infill drilling, and metallurgical and mineralogical evaluations, to confirm project economics.
- Placement of $360,000 to raise working capital.
McLaren Project, WA
McLaren VHMS Project (E69/2388 and E69/2386) comprises 333km2, located on the western side of the Eucla Basin, adjacent to the Fraser Range in Western Australia (Figure 1).
McLaren is an advanced-stage exploration project with an indicated and inferred Mineral Resource estimate of 280Mt @ 4.8% Heavy Mineral for 13.5Mt in-situ HM completed in 2022.
Allup Silica Managing Director Andrew Haythorpe said: "This Project presents an excellent opportunity for Allup Silica to fulfill its plan of moving into production. Albeit a different sand, the mining and washing processes for ilmenite are similar to silica sand, as well as the near-surface mineralisation and low strip ratios. However, the higher product price and lower shipping volumes present a compelling opportunity for development.
Because of the previous work completed and the increasingly high value of titanium minerals, this opportunity presents a faster and higher confidence pathway for Allup Silica and its shareholders. The ground is accessible in all seasons of the year, allowing for more rapid progress. Infill drilling and further metallurgical work is planned to commence as soon as practicable so that we can advance a Pre-Feasibility Study and move onto a Bankable Feasibility Study for the project."
