Regis Resources (ASX:RRL) drops a 270koz Beamish South resource on Garden Well’s doorstep

The McPhillamys cash machine has a quiet sibling at Duketon, and the drill bit just made it louder.

Regis Resources (ASX:RRL) has handed shareholders a mid-year exploration update that does something investors don’t usually get from a producing gold miner. It puts real ounces on the board across Duketon, McPhillamys and Tropicana in the same release.

The headline number is a new 270,000 ounce open pit Mineral Resource at Beamish South, sitting 3km from the Garden Well processing plant. The pit shell uses a A$3,900 per ounce gold price assumption, which is conservative against today’s spot price north of US$3,200.

Around that, Garden Well underground returned a 10.4m at 2.9g/t hit roughly 500m down-plunge of existing resources, Rosemont Stage 3 extended another 300m south, and Kings Plains near McPhillamys confirmed gold mineralisation to at least 180m depth. For a A$5 billion producer that just posted record cash flow, this is the boring but important work of replacing what gets mined.

The question is whether the market gives Regis credit for an organic growth pipeline that no longer relies on a single court case to deliver value.

Beamish South turns a drill program into a near-mine ounce factory

Beamish South sits in the same stratigraphic position as Garden Well and shares the same geology. That matters because Garden Well already has the haul roads, the people and a processing plant currently chewing through ore at A$2,850 per ounce cash cost.

Bolt-on satellites at this distance are valued differently to greenfield discoveries. There is no permitting marathon, no new camp, no separate workforce. The 270koz at 1.1g/t looks modest until you remember the marginal economics of feeding an underutilised mill.

Drilling is still running and the deposit plunges north, which Regis flags as offering both open pit and potential underground resource extensions. The skeptical read is that 1.1g/t is below Duketon’s reserve grade, so the upside case rests on growing the resource enough to justify a stand-alone pit design.

Garden Well’s 500m down-plunge hit reopens the underground question

The single most interesting drill result in this update is RRLGWDD008, which intersected 10.4m at 2.9g/t at 1,179m depth. That sits roughly 500m below the existing Garden Well resource envelope.

Regis disclosed an exploration target for Garden Well underground back in 2023 of 9 to 18Mt at 2.3 to 2.9g/t, or 0.8 to 1.3 million ounces. This drilling is the first material evidence that the lower bound of that target may understate the system.

Our concern is timing. Even if the next 12 months of infill drilling confirms an Inferred Resource at depth, an underground mine at 1.2km from surface needs years of definition before it contributes to reserves. The market tends to pay for ounces in reserves, not exploration targets.

Kings Plains gives McPhillamys a Plan B that does not need the Federal Court

Kings Plains sits less than 2km from the stalled McPhillamys project and is interpreted to share the same Godolphin Fault control on mineralisation. The new hole RRLKPDD001 returned 35m at 1.0g/t from 197m, extending gold mineralisation to at least 180m from surface.

This is a long way from being a resource, but it matters strategically. McPhillamys remains tied up in court over a heritage protection order on its tailings dam, and a satellite open pit at Kings Plains could eventually feed a processing hub that uses different infrastructure assumptions.

It is worth being clear that this is early-stage drilling on a single hole. Investors should treat Kings Plains as optionality on the broader Blayney district, not as a near-term catalyst.

The Investors Takeaway for Regis Resources

Today’s update will not move the share price on its own. What it does is reinforce that Regis is no longer just a gold price bet with one big court case attached.

The Duketon mill is filling its hopper from multiple new sources, Tropicana underground continues to push down-plunge with 22m at 9.5g/t hits, and Kings Plains creates a second McPhillamys-adjacent option that does not depend on the Federal Court. We covered the record half year and the dividend pivot in our last note at stocksdownunder, and the exploration pipeline is what defends that dividend policy through 2027 and beyond.

The next thing to watch is whether infill drilling at Beamish South and Garden Well underground translates into reserve additions at the next annual update. Until that happens, the market will keep paying for what is already in the ground.
