Resolute Mining (LSE:RSG) shares slumped Friday, falling 5.3% to 60.8p, after announcing that the Syama operation's second-quarter production was disrupted by logistical and supply-chain issues.
It also said performance is now expected at the lower end of guidance.
The miner said the majority of the problems stemmed from delayed deliveries of key equipment needed to mine higher‑grade A21 open‑pit sulphide zones; meanwhile, underground grades also fell after intermittent blasting performance and a temporary interruption to explosives supply, which saw greater reliance on lower‑grade stockpiles.
"Recent performance at Syama has been below expectations despite the significant changes implemented in Mali; these issues are well understood, and our focus is on stabilising operations and restoring consistent performance," said Chris Eger, Chief Executive Officer.
Resolute has deferred the planned May sulphide plant and roaster shutdown to mid‑June and extended it by one week for additional preventative maintenance, and it is working with contractors to deliver equipment by the shutdown end while increasing underground development, adding operators and accelerating open‑pit mining to access higher‑grade ore.
Despite the production setback, the company said the broader business remains cash‑generative on a positive gold price and disciplined costs.
Elsewhere, it noted that the Mako operation's stockpile processing is on track for full‑year guidance, the Doropo project construction remains on schedule.
Resolute plans to provide a detailed operational update with its June 2026 quarterly results in July.
