Q&A

Barton Gold, an Australian gold developer listed on the ASX under the code BGD, plans to make money from gold production, targeting c 150,000oz a year. It owns 100% of the only regional gold mill in the central Gawler Craton of South Australia. First, at its Challenger-Central Gawler Mill (CGM) complex, Barton plans a Stage 1 restart of the CGM, initially using historical, higher-grade tailings and limited near-surface material. The second stage would take Barton to target scale through bulk, lower-grade production from Tunkillia blended with high-grade ore from Tarcoola, from two mills in a regional hub-and-spoke model. At Tarcoola-Tolmer, Barton could delineate many millions of ounces of shallow silver resources if acceptable continuity is established in the silver zone. Results to date suggest that Tolmer merits attention in its own right as a prospective, shallow, high-grade asset.

Barton Gold plans to start producing gold by restarting the mill at its Challenger-CGM complex, and we expect commissioning of the fully permitted mill by the end of 2027, after the completion of a definitive feasibility study (DFS). Barton then plans to ramp the mill to 10–20koz a year in CY27/28 and 30–50koz a year from CY29/30. For Tunkillia (the second stage) Barton targets an ore reserve estimate and a pre-feasibility study (PFS), then a mining licence application. On 27 October 2026, Barton said it is targeting both the Challenger-CGM DFS and the Tunkillia PFS in Q1 CY27. Barton aims for Tunkillia production in c 2030–31 at 125koz a year or more, taking group output to its 150koz-a-year target. On 28 October 2026, after updating its Challenger underground resource to 230koz at 3.65g/t, Barton said it expects to start an expedited review of potential underground development options shortly.

Our valuation of Barton Gold is A$2.22 per share in 1 July 2026 money terms, the NPV10 of the dividends we estimate it can pay shareholders. It uses the US$3,333/oz gold price of the optimised scoping study, includes Challenger-CGM production and assumes an A$74.7m equity raise in FY28 to fund Tunkillia, at our August note's share price. At the then gold price of US$4,500/oz, this valuation more than doubles to A$4.78 per share. From the A$2.22 base, we expect our valuation to peak at A$3.25 per share, also in 1 July 2026 money terms, just before Barton's first material potential dividend in FY31 (June year end). Our risked valuations for Tunkillia, based on EV/project NPV multiples, are A$1.45–1.64 per share, and the Challenger-CGM complex adds a further c A$0.81 per share, largely in the form of lower future equity funding requirements.

The risks we attach to Barton Gold are the same as any pre-production mining company, namely sovereign, execution, geological, metallurgical, engineering and management (possibly including funding) risk, plus overall commerciality risk. At a long-term real gold price of US$3,333/oz in late-FY26 terms, we nevertheless value Barton at A$2.22 per share (assuming a A$74.7m future equity raise to fund Tunkillia at our August note's share price). At Challenger, Barton is applying for a new M-PEPR (mining licence), with the application targeted by the end of Q1 CY27.
