SSR–Roxmore $464M deal: Nevada gold mine capex and NPV lens for planners
Reviewed by Joe Ashwell

First reported on MINING.com
30 Second Briefing
SSR Mining will acquire Nevada-focused Roxmore Resources for C$660.1 million in cash, securing the Converse open-pit project 6 km west of its Marigold mine, where a PEA outlines 250,000 oz. per year over 15 years, with a post-tax NPV of $2.7 billion at $3,600/oz. gold and a 42.8% IRR. Converse, hosting 103 million indicated tonnes at 0.65 g/t and 218 million inferred tonnes at 0.43 g/t, could lift SSR’s US output to 350,000–400,000 oz. annually from 2033–2042, despite an $829 million initial capex. In parallel, an updated Marigold plan extends mine life to 20 years, boosts probable reserves 43% to 4.6 million oz., and more than triples post-tax NPV to $3.3 billion, with life-of-mine capex rising to $1.3 billion and Buffalo Valley (700,000 oz. reserves) feeding first ore from 2029.
Technical Brief
- Converse PEA assumes $829 million initial capex for an open-pit, heap-leach style development.
- Discounted at 5%, Converse delivers post-tax NPV of $2.7 billion and 42.8% IRR at $3,600/oz. gold.
- Resource base at Converse: 103 Mt indicated at 0.65 g/t (2.2 Moz) plus 218 Mt inferred at 0.43 g/t (3.0 Moz).
- SSR is paying C$660.1 million in cash for Roxmore, versus Roxmore’s C$502.1 million market value at announcement.
- Converse lies 6 km west of Marigold and ~275 km northeast of Carson City, enabling shared Nevada infrastructure.
- Updated Marigold plan lifts probable reserves to 4.6 Moz and life-of-mine production to 3.2 Moz, with $1.3 billion LOM capex.
- Buffalo Valley, 24 km southwest of Marigold, contributes 700,000 oz. probable reserves with first ore targeted in 2029.
- SSR plans near-term investment at Marigold in fleet upgrades and heap-leach pad expansions to improve flexibility and reliability.
Our Take
In our database, the planned US$1.5 billion cash inflow from selling SSR Mining’s 80% stake in the Çöpler mine (March 2026 coverage) is one of the larger single-asset divestments, which likely underpins the company’s ability to fund high-capex Nevada growth such as the US$829 million Converse build without over-reliance on debt.
The post-tax NPVs of US$3.3 billion for Marigold and US$2.7 billion for Converse at a 5% discount rate place SSR Mining’s Nevada gold portfolio toward the upper end of project value ranges seen in recent gold items in our coverage, signalling that the company is concentrating capital into a relatively high-margin, long-life cluster rather than a dispersed asset base.
The heap-leach pad failure at Çöpler that caused nine fatalities, combined with SSR’s pivot to large-scale heap-leach style operations at Marigold and Converse in Nevada, is likely to draw closer scrutiny from US regulators and insurers, which operators and contractors on these projects should anticipate in their design, monitoring, and contracting strategies.
