Tolu Minerals Builds Momentum Toward Tolukuma Gold Restart

Tolukuma Restart Moves From Exploration to Execution

Tolu Minerals Limited (ASX:TOK) is pitching Tolukuma as a near-term production restart rather than a conventional mine build, with first gold targeted in the first quarter of 2027. The Papua New Guinea operation is fully permitted and 100% owned, according to the company, and has an existing 220,000-tonne-per-year carbon-in-leach processing plant undergoing refurbishment.

The restart case has strengthened on paper since the company’s earlier resource work. Tolukuma now carries a 909,000-ounce gold Mineral Resource, while Tolu’s reported global resource base stands at 1.33 million ounces, including a 293,000-ounce Inferred resource at Mt Penck. The company’s presentation says full-rate production is targeted for the first half of 2028, although it does not provide a detailed production schedule, operating cost forecast or capital expenditure budget.

Existing Infrastructure Is Central to the Plan

Tolu’s argument rests heavily on the infrastructure already at Tolukuma. The mine historically produced about one million ounces of gold between 1995 and 2015, with reported recoveries of 92%, while a completed access road from Port Moresby is said to have reduced logistics costs by more than 75%. The company is also restoring the site’s hydro-electric station and refurbishing the existing plant rather than constructing a new processing facility.

Underground development is already advancing on three drives, including an ore drive at the 1560 Level. Tolu says face sampling there returned multiple results above 30 grams per tonne gold, with a peak sample of 176.9 g/t. It expects to build a stockpile of about 60,000 tonnes by the end of the first quarter of 2027, ready to feed the plant during commissioning. Those are company targets and operating updates, not evidence yet of sustained commercial production.

Drilling Supports the Near-Mine Growth Story

The presentation also puts the exploration engine firmly alongside the restart. Tolu says it had drilled 22,975 metres in 143 holes by 30 June, with seven rigs operating across a planned campaign exceeding 75,000 metres. The Tolukuma vein system extends more than eight kilometres, but only about 1.2 kilometres has been mined, and the company’s revised model recognises more than 44 veins and splays.

Recent highlighted intercepts include 3.2 metres at 70.8 g/t gold at Gulbadi Red, 3.9 metres at 42.3 g/t at Zine South and 4.7 metres at 40.9 g/t at Fundoot. Tolu says these structures sit within or near the existing mine footprint, potentially shortening the route from drilling to mine development. Exploration targets at Mt Penck and Ipi River add longer-dated upside, but the presentation explicitly describes those targets as conceptual and uncertain to convert into Mineral Resources.

Funding and Restart Risks Remain Material

Tolu reported approximately A$50 million in cash at 30 June 2026 and says recently announced financing takes its available funding to about A$65 million as at 22 September, leaving it fully funded through the restart. The presentation lists plant refurbishment completion in the fourth quarter of 2026, a new mine plan in the first quarter of 2027 and initial gold production in the same quarter.

That sequence leaves little room for slippage between refurbishment, underground development, commissioning and the mine plan. Tolu’s own disclosures flag commodity and currency movements, drilling and metallurgical results, cost estimates, approvals, landowner access, environmental and social risks, and Papua New Guinea’s political and regulatory environment. The next meaningful test is whether plant work and underground preparation translate the attractive resource and drilling figures into a reliable production start.
