Listed firm Apex Mining Co. Inc. on Wednesday said it has completed mitigation measures and the installation of interim systems at its mine in Compostela Valley, following a tailings leak last month.
In a disclosure to the Philippine Stock Exchange, Apex said that water near the Lumanggang Creek Diversion Pipe have been restored to normalcy after the company initiated immediate corrective mitigation measures, including voluntary suspension of its own operations to further prevent or alleviate potential effects brought about by the incident.
Apex first discovered the leak at the diversion pipe on January 15 after a weeklong, downpour of rain experienced in the area.
The company said it has immediately reported the incident to the Regional Office of Mines and Geosciences Bureau (MGB)-Region 11.
“This was immediately followed by their independent investigation, and, around 9 to 10 a.m. the situation was contained by the technical staff of Apex,” the company said.
On January 16, confirmation and validation was made by MGB-11, which was subsequently transmitted to the Environmental Management Bureau.
“The above findings of the MGB-11 showed that the effluents were within the usual limits except for some elevated presence of silt. During the EMB validation in the afternoon, there was a recurrence of a similar nature,” Apex said.
Apex said that implementation of a new watering system is underway for the permanent resolution and prevention of future incidents of similar nature.
“Notably, the incidents had no effect whatsoever to the structural integrity of the Maco Tailings Management Facility,” it added.
Apex is currently undergoing expansion program at its mine in Maco, Compostela Valley.
Under the program, the company aims to increase the mine’s capacity to 1,500 tons a day from the current 850 tons. New production zones within the mine are also being identified. James Konstantin Galvez
