Dragonflies belong to the order Odonata, which comprises true dragonflies (Anisoptera) and damselflies (Zygoptera). They inhabit a wide range of environments, including forests, gardens, rice fields, rivers and lakes.

Spending More Time in Water

Most of a dragonfly’s life cycle is spent as an aquatic larva or nymph, lasting from several months to several years. During this stage, dragonfly larvae prey on mosquito larvae, aquatic worms and other small organisms.

Because they require well-oxygenated and relatively clean water, dragonfly larvae are sensitive to changes in water quality. Pollution can reduce their populations, while improving water conditions can allow dragonflies to return.

A Natural Bioindicator

Their dependence on both aquatic and terrestrial habitats makes dragonflies bioindicators—organisms that can help reveal environmental conditions. Changes in the abundance and diversity of dragonfly species can signal changes in habitat quality.

The greater the diversity of dragonflies found in an area, the stronger the indication that the aquatic ecosystem is capable of supporting a wide range of organisms.

Part of the Food Chain

Dragonflies also contribute to maintaining ecosystem balance. Their larvae help control aquatic organisms, including mosquito larvae, while adult dragonflies prey on a variety of insects. At the same time, dragonflies serve as a food source for fish, birds, frogs, reptiles and bats.

As a result, a decline in dragonfly populations can affect the balance of the food chain.

Protecting Habitats, Sustaining Ecosystems

Land-use change, water pollution, excessive pesticide use, and shifts in rainfall patterns and temperature can threaten dragonfly populations. Maintaining water quality, protecting wetlands, preserving vegetation along riverbanks and restoring habitats are important measures for supporting their survival.

In river rehabilitation and the reclamation of former mining areas, dragonfly abundance and diversity can serve as one of the indicators of ecosystem recovery.

Ultimately, dragonflies remind us that environmental health can be reflected in the smallest creatures within an ecosystem. Protecting dragonfly habitats therefore also means safeguarding water quality, ecosystem balance and the many forms of life that depend on them.

This commitment continues to be reinforced through various environmental management initiatives consistently implemented by the Company, ranging from water quality management, air monitoring, waste management, biodiversity conservation, to the implementation of environmental monitoring systems conducted regularly and systematically.

Since the beginning of its operations, Agincourt Resources has continuously strengthened the implementation of good mining practice through technology-based approaches, layered monitoring systems, and the active involvement of multiple stakeholders in environmental monitoring processes. One of the Company’s key priorities is ensuring that all process water generated from operations meets required quality standards before being safely discharged back into the environment through strict and sustainable management practices.

Manager Environmental of Agincourt Resources, Mahmud Subagya, emphasised that environmental stewardship remains a top priority in every aspect of the Company’s operations.

“For Agincourt Resources, environmental management is not merely an operational obligation, but part of the Company’s long-term commitment to ensuring that mining activities are carried out responsibly, transparently, and continue to provide the highest level of environmental protection within and around our operational areas.”

Beyond internal environmental management efforts, the involvement of local government and surrounding communities also plays an important role in maintaining transparency in environmental oversight. Various routine monitoring activities are conducted together with integrated monitoring teams involving representatives from local government institutions, communities, and independent parties as part of an open and accountable monitoring mechanism.

The Regent of South Tapanuli, H. Gus Irawan Pasaribu, expressed his appreciation for Agincourt Resources’ consistency in maintaining its environmental management commitment and hopes that the Company’s mining practices will continue to serve as a model for responsible mining implementation across North Sumatra.

The remarks were delivered during the World Environment Day 2026 commemoration held at Sipirok Botanical Garden on 17th June 2026. “We highly appreciate Agincourt Resources’ continued commitment and serious efforts in implementing responsible environmental management. Collaboration between the Company, government, and communities serves as an important foundation to ensure operational activities remain aligned with environmental protection while delivering long-term benefits for regional development.”

In addition to ensuring compliance with environmental regulations, the Company continues to strengthen the implementation of Environmental, Social, and Governance (ESG) principles through land rehabilitation programmes, conservation efforts in the Batang Toru ecosystem, waste management initiatives, biodiversity monitoring, and the reinforcement of an operational culture focused on sustainability.

Through an adaptive, data-driven approach and the active involvement of multiple stakeholders, Agincourt Resources continues to demonstrate that mining activities can operate in harmony with environmental protection. This approach forms an important part of maintaining public trust while ensuring that the benefits of mining continue to be enjoyed by communities today and by future generations.

One of the elements that strengthens this process is community participation as part of an open and collaborative environmental monitoring mechanism. As part of its implementation of Good Mining Practice, Agincourt Resources involves local communities in routine environmental monitoring activities, including the integrated sampling process conducted at several monitoring points.

Through this approach, community representatives are directly involved alongside the Company and government authorities in wastewater sampling and water quality monitoring activities. Sampling points are determined transparently, while the sampling process follows standard procedures to ensure the validity and accuracy of the test results.

The parameters tested include various aspects of water quality, such as acidity levels (pH), Total Suspended Solids (TSS), heavy metal content, and other parameters in accordance with applicable environmental quality standards. The collected samples are subsequently analysed by accredited laboratories, with the results shared with all relevant parties, including the communities involved in the monitoring process.

Community involvement in this process not only strengthens transparency and accountability but also provides opportunities for local communities to gain a direct understanding of the environmental management mechanisms implemented by the Company. This approach plays an important role in building public trust while ensuring that monitoring activities are carried out in a more credible and transparent manner.

From an environmental management and compliance perspective, involving communities in routine monitoring activities also reflects the implementation of the Company’s Environmental, Social, and Governance (ESG) principles. In addition to supporting transparency, this initiative also encourages a more participatory and sustainable environmental monitoring process.

Through collaboration between the Company, government authorities, and local communities, environmental monitoring becomes not only a shared responsibility, but also part of a collective commitment to maintaining environmental sustainability in a responsible manner.
