Regis Resources (ASX: RRL) has declared its first official mineral resource at Beamish South in Western Australia. The move pushed RRL shares 3% higher on Friday, with the Regis Resources ASX RRL forecast drawing renewed investor attention across multiple gold assets.
Beamish South Delivers First Official Gold Resource at Duketon
The Beamish South resource declaration marks a turning point for Regis Resources’ Duketon gold project. For the first time, an exploration story at the site now carries a number that engineers can work with in mine planning.
Location of Regis Resources’ Duketon gold project
Regis Resources reported an initial JORC open-pit mineral resource for Beamish South of 7 million tonnes grading 1.1 g/t Au (270,000 ounces) at A$3,900/oz constrained within a pit, conservative against the recent spot price of greater than US$3,200.
Location Gives Beamish South a Cost Advantage
Beamish South sits just 3km from the Garden Well processing plant inside the Duketon belt. That distance matters more than the headline ounce count for most analysts reviewing the Regis Resources ASX RRL forecast.
Satellite deposits this close to existing infrastructure do not require new camps, separate workforces, or new permitting processes. The Garden Well plant already has haul roads and processing capacity in place, meaning any ore from Beamish South moves directly into an established production system with low incremental capital requirements.
Drilling Remains Open at Depth and Along Strike
Drilling at Beamish South is still running, with the deposit plunging north. Regis Resources flagged both open-pit and underground extensions as targets for follow-up programs.
The key test ahead is whether additional metres in the ground translate into a larger resource at the next update. Until that happens, the 270,000-ounce figure represents a floor, not a ceiling, for what Beamish South may ultimately contribute to the Duketon production profile.
Garden Well Underground Hit Reopens a Million-Ounce Question
The single most watched result in the June 2026 exploration update came from Garden Well underground. Regis Resources reported hole RRLGWDD008, which returned 10.4 metres at 2.9 grams per tonne gold at approximately 1,179 metres depth.
That intersection sits roughly 500 metres below the existing Garden Well resource envelope. Regis Resources had previously outlined an exploration target for the Garden Well underground system of 9 to 18 million tonnes grading between 2.3 and 2.9 grams per tonne, covering 0.8 to 1.3 million ounces. This new result is the first hard evidence that the lower end of that target range may be understating the system.
What the Deep Hit Means for the RRL Forecast
Analysts tracking the Regis Resources ASX RRL forecast will note that an underground mine at 1.2 kilometres from surface carries a long development timeline. Definition drilling, resource declaration, scoping studies, and feasibility work all stand between today’s intercept and future production.
However, the grade of 2.9 grams per tonne at depth is consistent with the upper range of the existing exploration target. That grade level, if sustained across further drilling, supports an underground development case that could extend Duketon’s mine life well into the next decade.
| Asset | Key Result | Depth | Grade |
| Beamish South | 270,000 oz resource | Open pit | 1.1 g/t Au |
| Garden Well Underground | 10.4m intersection | 1,179m | 2.9 g/t Au |
| Kings Plains | 35m intersection | 197m | 1.0 g/t Au |
| Tropicana | Multiple encouraging hits | Various | Not disclosed |
Kings Plains Gives McPhillamys a Backup Plan
The McPhillamys project in New South Wales remains in legal proceedings. A Federal Court challenge over a heritage protection order on the proposed tailings dam has kept the main project on hold. Against that backdrop, the Kings Plains drilling result carries strategic weight for any serious Regis Resources ASX RRL forecast.
Aerial view of McPhillamys project in New South Wales
Less than 2 km away from McPhillamys project limit is Kings Plains. Their first test pit, RRLKPDD001 for Regis Resources discovered gold of 1g /tonne in the interval 35m-197m down. Regis geologists also observed a Goddard Fault structure on site, equivalent to the on at McPhillamys. Gold identified by geologists to 180m below the surface, indicates it is associated with a geology controlling McPhillamys gold deposits.
Kings Plains Is Early Stage but Strategically Useful
One hole does not make a resource, and investors should treat Kings Plains as an early-stage option rather than a near-term catalyst. The deposit is not yet defined well enough for an economic assessment, and further drilling is required before any resource estimate can be attempted.
That said, a viable open-pit deposit at Kings Plains would give Regis Resources a separate pathway into the Blayney district infrastructure story. It would also reduce the company’s dependence on a single Federal Court outcome to unlock value from its New South Wales landholding.
Tropicana Adds Confidence Across a Third Asset Centre
At Tropicana in Western Australia, where Regis Resources holds a 30% interest alongside AngloGold Ashanti, the exploration update covered results from Boston Shaker, Tropicana Underground, Havana South, and the Swizzler area. Results across all four zones were described as encouraging, with drilling adding confidence to known mineralisation and supporting mine life extension potential.
Tropicana already carries a joint venture mineral resource of 5.4 million ounces following a February 2026 update. The new results build on that base rather than resetting expectations, reinforcing the asset’s contribution to the broader Regis Resources ASX RRL forecast through reserve replacement and underground growth.
Three Assets Moving Together Reduces Single-Project Risk
- Duketon delivering a new 270,000-ounce open-pit resource at Beamish South
- Garden Well underground returning a 2.9 g/t hit 500 metres below current resources
- Kings Plains opening a second McPhillamys-adjacent option in New South Wales
- Tropicana adding positive drilling data across four separate zones
The combined effect of these updates is that Regis Resources is advancing organic growth across three asset centres at the same time. That portfolio-wide movement reduces the company’s reliance on any single project to support its production and reserve outlook heading into FY27.
FAQS
Q1: What is the Regis Resources ASX RRL forecast following the Beamish South result?
A1: The Regis Resources ASX RRL forecast has turned more positive, with a new 270,000-ounce resource at Beamish South reducing depletion risk and shares rising 3% on the announcement date.
Q2: Where is Beamish South located?
A2: Beamish South sits 3km from the Garden Well processing plant within the Duketon gold project in Western Australia.
Q3: What did Regis Resources find at Garden Well underground?
A3: Regis Resources drilled 10.4 metres at 2.9g/t gold ~500 metres below the current resource, providing evidence to support possible an underground extension.
Q4: What is Kings Plains and why does it matter for Regis Resources?
A4: Kings Plains is an early-stage exploration target less than 2km from the stalled McPhillamys project. A single drill hole returned 35 metres at 1.0 gram per tonne, giving Regis Resources an alternative development option in New South Wales independent of its Federal Court case.
