Tivan (ASX:TVN) just locked in Timor-Leste JV terms and a Q4 maiden drill at Ossu

An 80/20 free-carry deal with a state-owned partner just turned the copper-gold story into a dated catalyst

Tivan (ASX:TVN) has signed Binding Term Sheets with Timor-Leste state-owned mining company Murak Rai Timor for joint ventures over the Baucau and Ossu copper-gold projects. The deal sets a clear path to long-form agreements by 30 September 2026 and, more importantly for investors, a maiden drilling program at Ossu in Q4 2026.

This is the missing piece of the Timor-Leste story. Tivan completed the acquisition of the projects in February 2026, but until you have the local state partner formally signed up under the country’s 2021 Mining Code, nothing actually moves. Now it does.

The structure matters. Tivan holds 80% of each JV company and Murak Rai holds 20%, with Murak Rai’s stake free carried all the way through to a Definitive Feasibility Study. That is about as clean a deal as a junior explorer can hope for in a frontier jurisdiction, and it means Tivan keeps the operational reins while sharing political alignment.

Until now, the market has largely been pricing Tivan on its Northern Territory tungsten story at Molyhil. The Timor-Leste copper-gold optionality has been quietly building in the background. Today’s announcement starts to put a date on when that optionality could turn into a real news flow event.

Why the JV structure is more generous than it looks

The free-carry term is the standout. Murak Rai contributes nothing to exploration or study costs until a DFS is complete, at which point it can either contribute pro rata, convert to a 4% net smelter royalty, or take a hybrid 10% plus 2% NSR option. For Tivan shareholders, that means 100% of the upside on every dollar spent between now and a feasibility decision.

It also means the dilution maths sits squarely with Tivan rather than being spread across the JV. That is a double-edged sword. The upside is undiluted, but so is the funding burden if Ossu turns into something serious.

The grades at Ossu are the reason this is worth watching

Rock chip samples from Ossu have returned up to 17.4% copper, 38.1 g/t gold and 0.45% cobalt. Those are eye-watering surface numbers, and they sit in a geological setting that hosts Grasberg, Ok Tedi and Wafi-Golpu. Timor-Leste is essentially the underexplored southern extension of one of the most prolific copper-gold belts on the planet.

The skeptical read is that rock chips are not a resource. High-grade surface samples in this style of geology can come from narrow structures that do not extend at depth. The Q4 2026 drill program is the test that matters, and a small one at that. Tivan has described it as a logistics shake-down ahead of more comprehensive work.

Where this sits alongside the Molyhil tungsten engine

Molyhil remains the cash flow story. The scoping study earlier in 2026 confirmed a low-complexity, gravity-led tungsten and molybdenum restart with Sumitomo Corporation circling as a potential funding partner, and the stock has run more than 300% over the past year on that thesis.

Timor-Leste is the exploration call option layered on top. If Ossu drilling intercepts meaningful copper-gold widths late in 2026, Tivan suddenly has two genuinely distinct catalysts pulling on the share price. We think the market has been treating the in-country work as background noise, and today’s announcement is the first step toward changing that read.

The Investors Takeaway for Tivan

From here, the sequence is reasonably tight. JV company incorporation by 31 July 2026, long-form JV agreements by 30 September 2026, and the drill rig turning at Ossu in Q4 2026. Each of those is a discrete milestone that gives the market something to price.

Investors who own Tivan for Molyhil now get the Timor-Leste catalyst essentially for free in the current share price. That is the genuinely interesting setup. Our previous coverage of the Molyhil scoping study at stocksdownunder framed Tivan as a tungsten re-rating story, and that thesis still holds. What is new is a second leg with a hard date attached, and a drill program that could materially change how this company is valued by year-end.
