The Most Mispriced Gold Story on the ASX

St Barbara (ASX:SBM) - $453M of cash, two world-class projects, and a market still pricing the ghosts.

About

St Barbara (SBM) is an Australian listed company with assets in Canada and Papua New Guinea, holding $453M in cash against a $644M market cap, and two projects worth multiples of the current enterprise value.

St Barbara has had a challenging half decade, most notably for mismanaging its assets and, as a result, paying the price. It’s been the most aggressively mispriced gold story on the ASX for the last six months.

On paper, the current key statistics are as follows:

• Ticker - SBM:ASX

• Price - $ 0.575 (As of 31/05/2026)

• Market Cap - $695 M

• Net Cash - $453 M (Excluding $83 M Atlantic Rehabilitation Bond)

• Enterprise Value - $191 M (Excluding $83 M Atlantic Rehabilitation Bond)

Thesis/Asymmetry

In April 2026, Lingbao Gold paid A$370M for half of Simberi. The market currently values everything SBM has left (the other 40% of Simberi, a 100% owned Canadian project carrying a $1.4bn PFS NPV, and A$453M of cash) at A$695M total. The math doesn’t math.

At spot gold (~$6,200/oz), both NPVs are materially higher than the numbers shown above. The 3.7× excludes any value for exploration, underground extension, or Tabar Islands. The market is paying SBM’s cash, plus a small premium for two projects worth multiples of the current EV. The key risks are as follows, all discussed later:

• CAPEX blowouts

• Simberi tax dispute

• Nova Scotia permitting

New Simberi Project, Papua New Guinea (40% Ownership)

On the 2nd of April 2026, SBM completed the sale of the New Simberi Gold project, selling 50% of the project to the Lingbao Gold Group Company Ltd (LB) and then both SBM and LB sold 20% (10% each) to the Kumul Mineral Holding Limited.

• LB is a state owned Chinese gold company with an MC of 25.5 B. The company operates in four main segments: mining in China, Kyrgyzstan, smelting, and Retailing. SBM received 370M from the 40% sale of the asset.

• Kumul Mineral Holding Limited is the Papua New Guinea (PNG) State Nominee for the share of the Simberi project. The price was $100 M for 20%, $50 M attributed to LB and SBM, respectively. This transaction will be paid through their share of metals revenue in the future, structurally aligning the government with the project. Further, an additional 20% of the farm in agreement with the remaining PNG tenements, the Tabar Islands Exploration.

The much flagged overhang in the Simberi catalyst is the SBM and PNG governments tax dispute over the alleged ‘fraudulent’ overclaiming of depreciation by using a shorter mine life. The dispute is $210M, including withholding and depreciation disputes, and it remains ongoing.

If the dispute is lost, the sale of the assets reduces SBM’s financial exposure. SBM agreed to pay the entire $35M withholding tax and fees associated with, but not the full remaining $170 M depreciation piece, which LB and Kumul will also have to bear (given that any deductions denied will be available in future years). The curveball is that Kumul has 20% of the project, which makes this a political risk mitigation strategy going forward, given the dispute’s new dynamic.

As a result of this transaction, SBM became overfunded for its initial share of the Simberi Expansion project, freeing up the balance sheet to advance other interests (discussed later). This project is essential to the asset’s life, as it can only currently mine the oxide ore. This will allow them to treat fresh sulphide ore and double their mining rate from 10 Mtpa to 20 Mtpa to feed the anticipated 3+Mtpa plant.

The “Feasibility Study confirms Simberi as a High Quality, Long-life, Low Cost Asset,” stating the capability to produce over 200koz pa at an AISC of $1,750 (US$1,250) per ounce. Using a gold price of $6,233 produces a margin of $4,483 per ounce, SBM’s cut of the pie will begin with roughly 80koz in FY29, showing a sustaining cash margin of $358 M per annum, and the ounce profile will only continue to grow from there, as shown below.

While the future and the operation’s unique attributes are important, it’s worth noting that Simberi is still in production and currently mining the remaining oxide ore body. This is a huge advantage, helping the balance sheet provide a buffer. In Q3 FY26, the project produced 11,974 oz at a realised price of $6,892 and an AISC of $4,323 per oz, resulting in a margin of $2,569 per oz. Continuing to mine the oxide ore is a significant advantage. Skilled, trained labour and equipment (16 Volvo A60S) are already on site and working, which increases the likelihood of a smooth transition to success when the ramp up begins.

SBM is at a unique stage of the Lassonde curve, making Simberi a standout in the space. Most developers are pre revenue and bleeding cash through the construction ‘orphan period’, while most producers have no growth catalyst, depleting their resources.

Simberi is generating cash from oxide production today while also having a well-defined catalyst for a significant increase in production. Investors don't have to choose between cash burn and future ounces or current cash flow and depletion. Simberi delivers both production cash today and near term growth from the same orebody. This is a rare setup, and the market is paying nothing for it.

The inclusion of LB as a partner has significantly de risked the project. The technical skill set they hold brings sulphide processing expertise, connections in a complex jurisdiction, hence the on time and on budget delivery is not guaranteed, it never is, but the probability distribution has tightened meaningfully with this partnership.

Nova Scotia Projects, Canada (100% Ownership)

Moving from the tropics of PNG to the Canadian Snow. Nova Scotia is where SBM’s value destruction story is most visible and where the mispricing by the market and brokers is most extreme.

The Nova Scotia Project, SBM, is 100% owned and was acquired from Atlantic Gold for C$723M in 2019, when the gold price was $1,795 per oz (at the time of the deal announcement). SBM has paid approximately $750M for an asset that has largely been in C&M due to permitting issues throughout the entire ownership period.

Essentially, SBM paid more for one asset six years ago than the company’s entire MC today, which, together with Gwalia (story for another time), explains the market’s concerns about the company. The board that completed those deals is largely gone, but the ghosts of SBM still appears in the register. Money of Mine tells the story quite well.

The Nova Scotia Projects’ development relies on project permitting, which looks a whole lot more positive than in recent years, thanks to the province’s improved permitting environment. With NexGold Mining’s Goldboro gold project, the province’s first new gold mine in over a decade has just become a reality. This has established a phased approval process, now being implemented, as a step to open the floodgates and set the precedent for the province.

SBM has successfully used the NexGolds framework to secure approval for the Touquoy stockpile restart project. The restart project is to process remnant medium and low grade stockpiles through the existing Touquoy processing plant, with a plan to produce 38koz over the 13 month period at an AISC of $2500 per ounce. This is a move to start with the fat (easy material), allow personnel to get boots on the ground, as seen in Simberi, and begin cash flowing the project.

The backbone of the project will be the 15 Mile Processing Hub, achieved by relocating the existing Touquoy mill and adding a larger ball mill. This is a deliberate method to minimise CAPEX while eliminating commissioning risk, which I believe will be prominent in the mining industry in FY27/28. The model being employed for Nova Scotia is the hub and spoke model, which, funnily enough, borrows directly from the Genesis playbook at Gwalia, ironic given Genesis was the buyer of Gwalia, and arguably the gift that saved SBM from receivership.

The numbers, the pre feasibility study put a post tax NPV of 1,402 M and an IRR of 80% at a gold price of $4200. At a gold price of 5,600 per oz, it yielded a post tax NPV of 2,302 M and an IRR of 122%. The initial capital for the project is estimated at approximately $310 million. This project will be funded by the cash flow generated from Simberi. At the current spot, the project sits well above the upper case estimate.

The Feed will be coming purely from the current proven and probable reserves from the following;

• 15-Mile Pit - 620 koz with 4 open pits

• Cochrane Hill - 390 koz with 1 open pit

• Beaver Dam - 220 koz with 1 open pit

Once permitted, the project’s exciting aspect is its multiple production hubs. This creates multiple mining fronts and will help de risk production targets by providing flexibility across multiple ore sources throughout the life of the operation. Metallurgically, the ore is known to be free milling, with gold averaging 95.3% recovery.

Beyond the 11 year mine life, there is a clear potential for significant value creation through underground extension, potential satellite discoveries on alternative tenements, and/or the transition from inferred resource to the measured category.

Final Thoughts

SBM is a story of historic capital destruction now giving way to capital creation. A board that repeatedly destroyed value has been replaced with a partnership structure designed to recapture it, in conjunction with a Canadian portfolio that has historically struggled to realise value, which now has a credible pathway forward.

Lingbao brings the technical and financial firepower SBM has lacked, Kumul brings the political and strategic alignment that Simberi has needed for a good while. The Goldboro precedent reduces the Nova Scotia permitting over hang that bogged down the Canadian assets for over half a decade.

The ghosts on the register are real, and they’re selling. The next chapter is being written with better partners and a materially better gold price than the market appears to be pricing. Based on my napkin math, these projects look to be very comfortably funded.

Two near term, ‘costless’ value accretive moves sit on the table for management. With a rebrand (the SBM ticker carries years of bag holder trauma that even a clean balance sheet can’t shake) and a competent IR (two ASX releases in a single day is amateur hour), the market can’t price what it can’t follow.

The value has been created in the ground, the management needs to ensure the market sees it.
