2015 SMPC Integrated Annual Report
Unong Mine rehabilitation
Unong Mine in Barangay Tinogboc was Semirara Island’s first open pit coal operations. It produced 12 million metric tons of coal in 1983 until 2000.
More than a decade since it closed, the mine area now has a lake that hosts meter-long eels, tilapia, and even some hawkbill sea turtles released in its brackish waters in 2011. The rim has become a wide band of green trees that line a three (3) -kilometer circumferential road. The company plans to develop the area as a place for recreation for island residents. Currently, the roads around the lake are enjoyed by bikers and weekend strollers, and a 1.1-kilometer zipline has been installed.
In 2014, the company started to develop land areas around the lake to plant Florida napier (Pennisetum purpureum), Pakchong 1 napier (cross of Pennisetum purpureum and Pennisetum glaucum), and star grass (Cynodon nlemfuensis) to support a dairy farm in the next one or two years. The dairy farm aims to produce enough milk to augment food and nutrition needs of children on the island.
