We investigate and evaluate the mining area and the areas likely to be affected by mining activities before we do mining, and then make the environmental impact assessment report. We evaluate the biological diversity in the affected areas and propose management solutions accordingly. For the national or local protected animals, plants or ecosystem, we protect the biological diversity through in situ conservation or ex-situ conservation. We negotiate with local governments, employees, affected communities and other stakeholders to make a joint plan about the social and environmental problems related with mine closure. We make plans for our financial and technical preparation to ensure a planned closure and the commitments after closure, including the land restoration, beneficial land for future use as well as the protection of water resources.

We do not conduct exploration, mining, and any construction activities within key areas such as nature reserves and ecologically vulnerable areas. We conduct ecological monitoring around the mines with high ecological risks. As at the end of 2021, we had carried out ecological diversity surveys in 18 mines. For example, Aurora set up hidden camera capture points at strategic locations around the mine to monitor and understand the ecology of the mine with minimal disruption to the natural habitat of wildlife. In the future, we will continue to pay attention to the biodiversity conservation strategies and action plans formulated by the countries (regions) where our projects are located, carry out detailed biodiversity surveys, and continuously improve the monitoring and protection mechanisms. In order to conserve the diversity of aquatic life in the rivers near the mines and improve the quality of the regional water environment, we select local fish species every year under the guidance of the local fishery departments and professional and technical experts, and carry out breeding and release activities in designated river locations to maintain the ecosystem of these rivers.

We protect endemic and precious plants by establishing new botanical gardens, reserved areas, and wetland reserves, and build ecological compensation forests to compensate for the damaged forest areas. In addition, we also actively participate in animal protection organisations. For example, Continental Gold has joined the National Animal Protection Organisation of Colombia. We create a suitable living environment for species through ecological restoration. We require that all mining areas should have the Mining Geological Environment Protection and Land Reclamation Plan. In the whole life cycle of mining, they should follow the mode of "exploring and managing at the same time" so as to minimize the land disturbance:
-In the early stage, we try to restore and rebuild the land by restoring the topsoil and planting native trees.
-In the late stage, we try to increase the biological diversity and enhance the stability of ecosystem by reasonable collocation of trees and shrubs.
-After the artificial ecological restoration is stable, we should gradually turn to the majority of natural restoration, with reduction of human intervention, so as to gradually realize the self-stability of ecosystem.
