Wheaton Precious Metals’ first Australian stream: what’s in the Jervois deal
Wheaton Precious Metals has signed a definitive gold and silver streaming agreement on the Jervois Copper Project in Australia with KGL Resources. It is Wheaton’s first streaming transaction in Australia – a top-tier mining jurisdiction – and the project is fully permitted with construction expected to start imminently.
In short, Wheaton pays upfront cash now in return for a percentage of Jervois’ future by-product gold and silver, then pays an ongoing 20% of spot for each ounce delivered. First production is targeted for the second half of 2027, with an initial 10-year mine life based on current reserves and resources.
US$275 million precious metals stream – the key commercial terms
| Counterparty | KGL Resources (ASX-listed), Jervois Copper Project, Northern Territory, Australia |
| Total upfront consideration | US$275 million |
| Early deposits | US$16 million + US$16 million (expected Q2 and Q3 2026, subject to conditions) |
| Remainder | US$243 million in four equal instalments during construction (US$60.75 million each) |
| Ongoing production payment | 20% of spot price for gold and silver delivered |
| First production | H2 2027 (projected) |
| Mine life assumption | 10 years based on reserves and resources, with exploration upside |
| Security | Corporate guarantees and first-priority security over project and KGL corporate assets (subject to permitted encumbrances) |
Gold stream – how the “dropdowns” work
- Wheaton buys 75% of payable gold until 45 thousand ounces (Koz) are delivered.
- Then 37.5% of payable gold until a further 15 Koz are delivered.
- Then 25% of payable gold for the life of mine.
- “Payable” uses a fixed 90% payability factor – i.e. delivered ounces are calculated at 90% of contained metal.
- The first threshold can be adjusted if deliveries are delayed versus an agreed schedule.
Silver stream – mirror structure with larger volumes
- Wheaton buys 75% of payable silver until approximately 4.3 million ounces (Moz) are delivered.
- Then 37.5% until an additional 1.7 Moz are delivered.
- Then 25% for the life of mine.
- Payability also fixed at 90%.
Cost overrun option adds torque to silver
There is a cost overrun stream of up to US$25 million available before the fifth anniversary of the effective date. If drawn, the initial silver percentage increases from 75% to 90%, with related threshold adjustments. That gives Wheaton extra silver exposure precisely when projects sometimes need it most – during build.
What Wheaton stands to receive: production profile and reserve uplift
Based on the feasibility schedule, Wheaton’s attributable stream volumes are forecast to average approximately 5.8 Koz of gold and 0.77 Moz of silver per year over the first five full years. Over the life of mine, the average is approximately 5.3 Koz gold and 0.59 Moz silver per year. The step-down thresholds front-load Wheaton’s exposure, which is attractive if early years are strong.
The deal also swells Wheaton’s inventory of metal on paper. Jervois adds estimated Proven and Probable reserves of 92 Koz gold and 9.2 Moz silver, plus Measured and Indicated resources of 15 Koz gold and 1.3 Moz silver and Inferred resources of 21 Koz gold and 2.1 Moz silver.
| Incremental to Wheaton from Jervois | |
|---|---|
| Proven & Probable reserves | 92 Koz gold, 9.2 Moz silver |
| Measured & Indicated resources | 15 Koz gold, 1.3 Moz silver |
| Inferred resources | 21 Koz gold, 2.1 Moz silver |
Structure, protections and financing: de-risking the build
- Completion test – customary checks against expected production and mining rates before the stream fully settles in.
- Security package – first-priority security over project and corporate assets, subject to an agreed intercreditor framework if project debt is added.
- Right of first refusal – Wheaton gets first look at any future Jervois precious metal streams, royalties, prepays or similar.
- Change of control – if KGL changes hands before 31 December 2029, KGL may buy back one third of the stream at a price delivering a pre-determined return.
- Equity participation – Wheaton has committed to participate in a future KGL equity raise for up to AU$35 million or 20% of the offered shares (capped so Wheaton’s ownership stays below 9.9%).
- Funding plan – Wheaton expects to fund most of the upfront from operating cash flow as construction advances. Management points to strong projected cash flow over the next five years and anticipated production growth of approximately 50% by 2030.
Why this matters for investors
This is a classic Wheaton move: deploy capital into a by-product precious metals stream on a copper project in a low-risk jurisdiction. The 20% of spot production payment leaves ample margin to Wheaton across cycles, and the 75% headline percentage – before the dropdowns – gives meaningful exposure in the early years.
Strategically, it diversifies Wheaton into Australia while backing a fully permitted project that is “on the cusp of breaking ground”. The cost overrun option adds flexibility to keep the build on track, and the right of first refusal protects future optionality if Jervois grows through exploration.
There are, of course, risks. Construction schedules can slip – the RNS explicitly allows for threshold adjustments if deliveries are delayed. The mine life is currently 10 years, which is respectable but not long in streaming terms, so exploration success will matter. Wheaton also relies on KGL executing the plan and securing any complementary project finance – hence the security package, completion test and equity participation.
On balance, the terms look shareholder-friendly: staged payments tie cash outflow to project progress, the completion test and security reduce downside, and the early high-percentage capture could make the first five years particularly accretive if Jervois ramps as planned.
Jargon buster
- Streaming agreement – upfront payment today for the right to buy a share of future mine production at a fixed discount to spot.
- Payability – the percentage of contained metal that is paid for under smelter/refinery terms (fixed at 90% here).
- Koz/Moz – thousand ounces/million ounces.
Key data points at a glance

| Average attributable production (years 1–5) | ~5.8 Koz gold, ~0.77 Moz silver per year |

My take
For Wheaton shareholders, this reads as a solid, well-structured addition: first-rate jurisdiction, near-term start, strong early-year capture and sensible protections. The mine life could prove short if exploration underdelivers, but the dropdown structure, 20% of spot payment and security package make the risk-reward look favourable. If Jervois hits its marks, this stream should be neatly accretive to Wheaton’s production and cash flow through the next decade.
