Rumble Resources Launches Three-Project WA Drill Push for Q4 Gold Results
Key Takeaways
- Rumble Resources has launched a sequential three-project drilling campaign across Western Australia, with all programs at Wardawarra, Munarra Gully, and Thunderstorm scheduled to deliver results before the end of 2026.
- The Munarra Gully follow-up program was triggered by MGRC26011 — the project's highest-grade intercept to date at 13m @ 21.64 g/t Au, including a 1m core at 221 g/t Au, within a previously undrilled 300-metre gap.
- Western Queen holds a June 2026 Mineral Resource Estimate of 5.13Mt @ 2.6 g/t Au for 433,600oz, with a Toll Milling Agreement already signed with Kirkalocka Gold SPV and an Updated Scoping Study due late September 2026.
- The Thunderstorm Gold Project covers 601km² and will see its first-ever fresh rock drilling program in late 2026, following heritage clearance of 7,400m of drill lines — with high-grade IGO results at Gazelle (16m @ 6.69 g/t Au) never previously followed up.
- Four distinct catalysts are expected within roughly three months, spanning gold, copper, and tungsten targets across three geologically distinct Western Australian settings.
Rumble Resources fires up three-front drilling campaign ahead of news-rich Q4
Rumble Resources (ASX: RTR) has launched a rolling three-project drilling campaign across Western Australia, with programs at Western Queen/Wardawarra, Munarra Gully, and Fraser Range/Thunderstorm all scheduled to deliver results before the end of 2026. Rather than running simultaneously, the rigs will move sequentially between projects — a deliberate sequencing strategy designed to generate a concentrated burst of news flow through the final quarter of the year.
Managing Director and CEO Peter Harold captured the intent plainly:

Three projects, three catalysts — what’s on the drill schedule
Western Queen/Wardawarra — Up to 5,000m aircore program commencing mid-September
The first cab off the rank is the Wardawarra program, located approximately 7km north of Western Queen Central along the Western Queen Shear Zone. Key details:
- Up to 5,000m of aircore drilling, commencing mid-September 2026
- Target area of approximately 2km x 1km
- Model Earth Global Geological Services conducted a structural review identifying three structural positions with similar kinematics to the Western Queen deposits; Wardawarra is the priority target
- Heritage survey with the Wajarri Yamaji People was completed in August 2026 — the program is clear to proceed
- Successful aircore results will be followed up with slimline RC holes
Munarra Gully — follow-up RC and diamond program commencing October
Once the Wardawarra rig moves on, attention turns to Munarra Gully — and the result that triggered this follow-up program is exceptional. Hole MGRC26011 returned the highest-grade intercept at the Munarra Gully Project to date:
- 13m @ 21.64 g/t Au from 122m
- including 5m @ 55.56 g/t Au from 124m
- including 1m @ 221.00 g/t Au from 124m
- concurrent with 7m @ 0.52% Cu from 128m
This result occurred within a 300m gap in previous effective drilling. The planned follow-up program includes one diamond hole to twin MGRC26011, which will help geologists determine the structural orientation of the gold-hosting structures. Closely spaced RC holes will then test to the north, south, and at depth to extend the high-grade trend. Deeper drilling also aims to vector towards Volcanogenic Massive Sulphide (VMS) copper targets, which the Amaryllis Shear Zone is interpreted to be overprinting.
The precedent for this follow-up campaign was set by the discovery hole itself; earlier coverage of bonanza gold at Munarra Gully detailed the geological context behind MGRC26011 and why the 300m gap in previous drilling made this intercept particularly significant.
Fraser Range/Thunderstorm — up to 5,000m AC/RC program planned for late 2026
The Thunderstorm Gold Project covers 601km² over the Newman Shear Zone in the Fraser Range region of WA. Previous work by previous joint venture partner IGO returned high-grade results at two prospects that were never followed up:
- Gazelle best results: 16m @ 6.69 g/t Au from 42m, including 4m @ 22.2 g/t Au from 50m; and 6m @ 9.15 g/t Au from 48m
- Pion best result: 4m @ 3.80 g/t Au from 86m
A heritage survey with the Ngadju People was completed in July 2026, with 7,400m of drill lines cleared. The planned program of up to 5,000m of aircore and RC drilling will be the first to test fresh rock at the project, targeting both paleochannel and structurally hosted basement gold.
| Project | Program Type | Size | Start Timing | Key Target |
|---|---|---|---|---|
| Western Queen/Wardawarra | Aircore (+ RC follow-up) | Up to 5,000m | Mid-September 2026 | Gold/tungsten along Western Queen Shear Zone |
| Munarra Gully | RC + Diamond | TBC | October 2026 | Expand high-grade Au-Cu at MGRC26011 |
| Fraser Range/Thunderstorm | Aircore + RC | Up to 5,000m | Late 2026 | Paleochannel and basement gold at Gazelle/Pion |
What makes these grade numbers stand out — a plain-English guide to gold intercepts
When a mining company reports a drill intercept, three numbers tell most of the story: width (in metres), grade (in grams per tonne, or g/t), and depth (how far below surface). Width tells you how thick the mineralised zone is; grade tells you how concentrated the gold is; depth matters because shallower deposits are generally cheaper to mine. The best results combine meaningful width, high grade, and accessible depth.
Context helps here. A typical open-pit gold mine might operate economically at grades around 1–2 g/t Au. The Munarra Gully intercept of 13m @ 21.64 g/t Au is already well above that bar. But the inner high-grade core — 1m @ 221.00 g/t Au — falls into a category geologists call “bonanza grade.” Even in a narrow width, concentrations at that level signal that the mineralising system is intensely active, which can indicate something larger beneath.
The concurrent copper result (7m @ 0.52% Cu) adds another dimension. Projects with both gold and copper mineralisation can potentially generate revenue from two commodities, which can improve the economics of a project compared to single-commodity deposits. The interpreted VMS copper target beneath Munarra Gully adds further depth to what the project could become.
Understanding the drilling sequence also helps. Aircore drilling is a cost-effective tool for screening large areas of ground — it drills quickly and cheaply to identify where mineralisation exists. Reverse circulation (RC) and diamond drilling are then used to follow up in detail: confirming grades, determining the geometry of the ore body, and providing core samples for structural analysis. The Wardawarra and Thunderstorm programs use aircore first precisely because they are testing large, untested areas before committing to more expensive follow-up work.
Western Queen mine development running parallel to exploration push
The exploration campaign is not happening in isolation. Rumble is simultaneously advancing Western Queen towards production, and the two workstreams are designed to complement each other.
Key milestones in the development pathway include:
- Resource base: 5.13Mt @ 2.6 g/t Au for 433,600oz contained gold (June 2026 Mineral Resource Estimate update), including Indicated Resources of 2.46Mt @ 2.9 g/t Au for 227,700oz
- Processing solution: Toll Milling and Blending Agreement signed in May 2026 with Gylden Resources Pty Ltd and Kirkalocka Gold SPV Pty Ltd for ore to be treated at the Kirkalocka plant, approximately 180km southeast of Western Queen
- Updated Scoping Study covering Western Queen South and Central is due to be released in late September 2026
- First ore is targeted approximately six months after the decline commences, following dewatering of the Western Queen South pit
Securing the water licence for Western Queen was a prerequisite milestone for the dewatering program required before the decline can commence, and it cleared one of the key regulatory hurdles separating the project from its first-ore target.
The project’s historical production credentials provide useful context: Western Queen produced 215,000oz at 7.6 g/t Au from previous operations, validating the gold endowment at the site. The Wardawarra drilling is targeting strike extensions along the same shear zone — results there could potentially add to the resource base underpinning the mine plan.

What investors should be watching between now and December 2026
The company has disclosed a clearly sequenced set of near-term catalysts, all expected within a single calendar window:
- Wardawarra aircore assay results — program commencing mid-September 2026
- Updated Scoping Study release — targeted late September 2026
- Munarra Gully RC and diamond drill results — program commencing October 2026
- Thunderstorm aircore/RC drill results — planned for late 2026
Four distinct catalysts in roughly three months is a concentrated news flow schedule for a company of Rumble’s size. Each program tests a different geological setting and commodity mix — Wardawarra adds gold and tungsten exposure along a proven structural corridor, Munarra Gully carries both gold and copper upside, and Thunderstorm will see its first drill program testing fresh rock (unweathered basement). Collectively, Rumble’s active project pipeline spans multiple geological settings across Western Australia, with gold as the primary target and tungsten and copper as meaningful secondary exposures.
