What caused the production disruptions at Resolute Mining’s (ASX:RSG) Syama Gold Mine?

Resolute Mining experienced severe logistical and supply chain disruptions during the second quarter of 2026 due to regional security challenges in Mali throughout late April and May.

How are the security challenges in Mali affecting operations at the Syama Gold Mine?

The equipment delays have stalled access to higher-grade sulphide ore zones within the A21 open pit. Additionally, a temporary shortage of explosives and intermittent blasting performance forced the sulphide mill to rely on lower-grade stockpiles, reducing overall gold output for the quarter.

Did Resolute Mining (ASX:RSG) change its full-year production guidance after this news?

Management did not officially lower its full-year guidance range of 195,000 to 210,000 ounces (koz) of gold. However, they confirmed that second-quarter production will fall below initial targets, causing full-year volumes to track toward the lower end of that guidance range.

What is Resolute Mining doing to fix the operational issues at the Syama Gold Mine?

Management is actively working with contractors to secure delayed equipment, increasing underground development capacity, and accelerating open-pit mining to regain access to higher-grade fresh ore. They are also implementing processing optimisation initiatives to improve total plant throughput for the rest of the year.

Why did Resolute Mining delay its scheduled plant maintenance shutdown?

The planned three-week maintenance shutdown for the sulphide plant and roaster was deferred from May to mid-June 2026 due to the volatile local security conditions. Management also extended the shutdown by one week to perform additional preventative maintenance, aiming to increase long-term plant availability.

Mali Security issues disrupt Resolute Mining production

West Africa-focused gold miner Resolute Mining (ASX:RSG) issued an operational update for its Syama Gold Mine in Mali, revealing that second-quarter production for 2026 has been hit by severe logistical and supply chain disruptions.

The setbacks stem from regional security challenges emerging in late April and May, which have compromised road safety and delayed the delivery of critical mining equipment.

Delays in receiving heavy machinery have stalled access to higher-grade sulphide ore zones within the A21 open pit.

Intermittent blasting performance and a temporary shortage of explosive supplies have forced the sulphide mill to rely heavily on lower-grade stockpiles.

Management expects Q2 production to fall below initial targets, tracking towards the lower end of its full-year guidance of 195 to 210 koz.

Resolute has deferred a planned three-week maintenance shutdown of the sulphide plant and roaster from May to mid-June, extending it by an extra week to conduct further preventative maintenance.

To stabilise operations, the company is actively collaborating with contractors to secure equipment, boosting underground development capacity, and accelerating open-pit mining to reclaim higher-grade ore.

Management remains optimistic that these mitigation actions, alongside the processing optimisation initiatives currently underway, will steadily improve plant throughput and restore operational performance for the remainder of the year as the security situation stabilises.

At the time of reporting, Resolute Mining’s share price was $1.10.
