Co-O Operations - Tropical Storm Sendong (Washi)

(ASX & LSE: MML)

Medusa Mining Limited ("Medusa" or the "Company"), through its Philippines operating company Philsaga Mining Corporation, advises that tropical storm Sendong (Washi) passed to the north of the Co-O operations during Friday-Saturday 15th and 16th December bringing strong gusting winds and heavy rainfall to area surrounding the mine and mill.

Winds from the storm have caused roofing damage to the laboratory and mill buildings with subsequent water ingress, and torrential rain has damaged in parts the 11 kilometres of haul road between the mine and the mill. The mine has not suffered any damage and remains operational.

The partly damaged haul road will limit ore haulage until it dries out and repairs are completed. Repairs will commence once the rain eases and a full assessment of the repair work and the time required is completed. Further information on possible effects to production will be provided in the December quarterly report.

The Company will be providing assistance where possible to local communities that have been affected by the storm.

From available information, it appears that the last similar tropical storm to visit Mindanao was over 20 years ago in the mid-1980s in the Surigao district located approximately 3 hours drive to the north of the Co-O operations.
