Sibanye-Stillwater unveils strong mineral resources and reserves across global portfolio
PGMs lead the way as diversified assets support long-life, sustainable production
Mining major Sibanye-Stillwater has once again underscored the scale of its global footprint, reporting sizeable mineral resources and reserves across its platinum group metals (PGMs), gold, and battery metals portfolio.
The numbers tell a compelling story of depth, diversification, and durability.
PGMs: The Cornerstone of the Portfolio
The four-element platinum group metals (PGMs) at the company’s South African PGM operations total an impressive 177.3-million resource ounces (-2.0%) and 29.4-million reserve ounces (+4.7%).
While resources saw a marginal decline, the increase in reserves reflects operational optimisation and confidence in long-term production planning. These assets remain central to Sibanye-Stillwater’s value proposition, anchoring its position as a leading global PGM producer.
Across the Atlantic, the company’s US PGM operations reported two-element PGMs totalling 80.9-million resource ounces (+2.2%) and 19.4-million reserve ounces (+2.1%). The steady growth in both categories’ signals stability and consistent performance in a critical market.
Gold and Uranium Add Depth
Gold continues to play a strategic role in the group’s portfolio. South African gold operations, including DRDGOLD and Burnstone, host gold resources of 36.4-million ounces (-25.5%) and reserves of 9.4-million ounces (-6.3%).
Although these figures reflect depletion and portfolio adjustments, the remaining resource base still supports ongoing production and cash generation.
In addition, South African gold operations host 59.3-million pounds of uranium oxide resources (+0.1%) and 25.2-million pounds of uranium oxide reserves, reinforcing the multi-commodity nature of the group’s asset base.
Battery and Base Metals Position for the Future
Looking ahead, Sibanye-Stillwater’s exposure to energy transition metals strengthens its strategic outlook.
Lithium resources total 510 000 t lithium carbonate equivalent (-24.0%), with reserves steady at 248 000 t. Zinc resources amount to 963 000 t (-17.4%) with reserves of 308 000 t (-44.2%), while copper resources stand at 5 500 000 t (-31.1%) and reserves at 478 000 t.
Despite some year-on-year reductions due to revised planning assumptions and mining depletion, the scale of these assets underscores the company’s commitment to participating in future-facing supply chains.
Long-Life Production Backed by Rigorous Planning
The declared resources and reserves for the group’s managed operations and projects are the outcome of a detailed annual operational and life-of-mine planning process and are indicative of the considerable underlying asset base which supports sustainable, long-life production, Sibanye-Stillwater stated.
Taken together, the latest declaration highlights more than just updated figures. It reflects a diversified mining group balancing precious metals with battery and base metals, underpinned by structured life-of-mine planning and global operational reach.
For investors and industry watchers alike, Sibanye-Stillwater’s latest resource update reinforces one clear message: the company’s asset base remains substantial, strategic, and built for longevity.
