Amman Mineral Successfully Reclaims 690.83 Hectares of Former Mine Area

The company is committed to implementing a standard of excellence for its environmental management by conducting land reclamation concurrently with mining operations. Reclamation of a 690.83-hectare former mine area of 2,722.45 hectares cleared for mining areas and supporting facilities has successfully been completed.

West Sumbawa, November 16, 2018 - Concurrently with the mining operation, PT Amman Mineral Nusa Tenggara ("Amman Mineral") has carried out reclamation on the area cleared for Batu Hijau mining area and other supporting facilities. The reclamation was carried out soon on the areas where mining operations had been completed to prevent erosion from occurring, maintain the stability of the slope structure, and reshape the structure and diversity of the vegetation similar to the one prior to mining operations in accordance with its final designation, and if possible, support the formation of certain plant species playing an important role in returning wildlife habitat.

Ecological monitoring is also carried out intensively to ensure that the reclamation activities have been done effectively to meet the objectives. Results of the monitoring conducted in the Batu Hijau reclamation area show the recovery in environmental quality as indicated by improved soil fertility, improved local climate, the diversity of tree species planted, and the occupation of reclamation areas as habitat for Batu Hijau native wildlife, such as deer, partridges, civets, bats, bondol eagles, and other wildlife.

Amman Mineral's Head of Corporate Communications, Anita Avianty, said, "Every year the Ministry of EMR verifies and assesses the success of the reclamation we have done based on the success criteria stipulated in Decree of the Minister of EMR No. 1827/2018. In general, in respect of the 5-year old reclamation area at Batu Hijau, we have fulfilled all the success criteria stipulated in the Decree. "

As of September 2018, the company has reclaimed 690.83 hectares of 2,722.45 hectares of the area cleared for mining areas and other supporting facilities. More than 900 thousand trees and more than 90 Batu Hijau native tree species are planted in the reclamation area, both tree species for production with an economic value and tree species of ecological and conservation importance. Anita added, "The trees in this reclamation area provide a place to live and food that supports the biodiversity of the Batu Hijau native fauna. The more diverse the species of trees are, the more diverse the fauna that makes them their habitat.”

At the reclamation stage, to prevent erosion on the slopes the company used coconet coconut fibers produced by a local business unit developed under the supervision of the company in Maluk Village, Sekongkang District, West Sumbawa. During 2018, the company has bought 9,000 rollers of coconet or an average of 1,000 rollers per month from the business unit in accordance with the 2018 reclamation size plan.

"The coconet coconut fiber processing business unit is one of our environmental programs by empowering the community and utilizing local resources because we need the products to meet the mining reclamation requirements," explained Anita. "Empowering local communities by utilizing local resources is what we continue to develop through corporate social responsibility programs to create self-reliant communities around the Batu Hijau mine," Anita added.

Effective 2019 the company will develop a Trigona SP honey bee farming project in the reclamation area relinquished. This project is expected to be one of the success indicators of reclamation that exceeds the requirements set by the government (beyond compliance). Trigona SP honey bees are considered to be the appropriate subject for this project because they do not sting (minimum risk) and survive in a warm and dry climate such as Batu Hijau.
