A 6.9 magnitude earthquake in February is still having repercussions at Medusa Mining’s operations in the Philippines.
A combination of the earthquake and heavy rains in December forced the miner to take its four large leach tanks off line due to subsidence of their footings, which caused the tanks to tilt.
While the miner was planning to fix the issue in June, recent inspections have shown that the tilting problem has worsened.
Due to this, all of its tanks have been taken off-line until they have been repaired.
Remedial work on the tanks is expected to take between four and five months, and will begin in April.
The shutdown of the tanks will cut throughput down to around 700 tonnes per day for the quarter.
This, in addition to extra electrical upgrades on its mills, has seen the miner revise its production to between 60 000 and 65 000 ounces.
However it added that all expansion work, including the Saga Shaft, underground development, and the new mill construction is on schedule.
