PETALING JAYA: Malaysia Smelting Corp
Bhd’s (MSC) 80%-owned subsidiary Rahman Hydraulic Tin Sdn Bhd (RHT) has been ordered to temporarily suspend its mining operations by the Perak Department of Minerals and Geosciences (JMG Perak), effective Aug 12, 2026.
The directive followed a site inspection by JMG Perak after an extreme rainfall event on Aug 3, when about 60mm of rain fell within an hour, exceeding the 50mm maximum design intensity of RHT’s existing drainage and retention pond infrastructure.
MSC said the heavy rainfall damaged certain drainage facilities and overwhelmed the retention ponds, prompting the temporary suspension.
“Under normal operating conditions, RHT operates a closed loop water management system with no routine discharge of process water from its mining operations into the nearby river.
“Process water is retained and recirculated within the mine’s reservoirs, while water quality is managed through lime dosing to neutralise acidity and regular sampling conducted at designated monitoring points within the mine.”
MSC said RHT has commenced the necessary repair and upgrading works and is engaging with JMG Perak on a comprehensive remedial action plan.
“The temporary suspension will remain in effect until further notice from JMG Perak.
“As the duration of the suspension is subject to clearance by JMG Perak, the financial impact on the group cannot be determined at this juncture.
MSC said its tin smelting operations, which form a separate core business segment, are not affected by the directive and continue to operate as usual.
