RGD Reunion Gold Corp

Reunion Gold Corporation (TSXV: RGD; OTCQX: RGDFF) (the “Company”) is pleased to announce that the Environmental Protection Agency (“EPA”) of the government of Guyana has finalized and approved the Terms of Scope (“ToS”) for the Environmental and Social Impact Assessment (“ESIA”) on the Oko West Project in Guyana’s Region 7.

Rick Howes, President & CEO of Reunion Gold, commented, “We are very pleased that the EPA has approved the Terms of Scope for the ESIA on Oko West, as this represents a significant milestone in the advancement of the permitting process for the project. The Company remains on track with its accelerated development timeline for Oko West, which includes the completion of a preliminary economic assessment (“PEA”) by the end of Q2 2024.”

The Company applied to the EPA for its environmental permit in September 2023 and subsequently collaborated with the EPA to establish the ToS for the ESIA. As part of this process, the Company conducted meetings with both government agencies and local communities in Q4 2023 to determine the essential elements to be incorporated into the ToS. The approval of the ToS is required for the Company to move forward with work on the ESIA, which it anticipates submitting early in Q4 2024.

In addition to the approval of the ToS, the Company has completed most of the environmental and social baseline studies that are required for the ESIA. This includes the fieldwork for the second phase of baseline studies, encompassing the physical baseline (groundwater and air quality), the biological baseline (plant, animal and aquatic ecosystems) and additional community meetings. These community meetings were conducted to assess the current socio-economic and health baselines, as well as any potential cultural heritage considerations.

Following the expected completion of its PEA in Q2 2024, the Company plans to advance work on both the feasibility study and the environmental permits throughout the remainder of 2024 and into the first quarter of 2025, with the expectation of being in a position to consider a construction decision in Q2 2025.
