Additional Drill Results Highlighted by Hole D-380 in Block 6 at Oko West, Intersecting 39.7 m Grading 5.27 g/t Au Including 2.8 m @ 14.18 g/t Au and 13.0 m Grading 10.50 g/t Au

LONGUEUIL, Quebec, March 28, 2024 (GLOBE NEWSWIRE) — Reunion Gold Corporation (TSXV: RGD; OTCQX: RGDFF) (the “Company”) is pleased to announce additional drill results from its ongoing infill and step out drill program at the Kairuni zone on its Oko West project in Guyana. Hole D-380, which is located in Block 6 (see Table 1 and Figure 1) intersected 39.7 meters (“m”) @ 5.27 grams per tonne of gold (“g/t Au”) from 152.3 m downhole (using a 0.3 g/t Au cutoff), including 3.8 m @ 14.18 g/t Au and 13.0 m @ 10.50 g/t Au (using 1.5 g/t Au cutoffs). The results from Hole D-380 are encouraging as they indicate the potential for additional high-grade mineralized shoots to be defined in areas of existing wider drill spacing where the current infill continues. Downdip from D-380 and also within Block 6, drill hole D-392 intersected 70.3 m @ 1.08 g/t Au from 193.0m downhole, including 12.0 m @ 3.42 g/t Au.

On the northern margin of Block 4, Hole D-377, which is located on the northern margin of the Block 4 high grade zone (see Table 2 and Figure 1), intersected 55.0 m @ 2.42 g/t Au from 645 m downhole (using a 0.3 g/t Au cutoff), including 5.5 m @ 5.97 g/t Au and 20.4 m @ 3.42 g/t Au (using a 1.5 g/t Au cutoff).

Rick Howes, President & CEO of Reunion Gold, commented, “It is encouraging to see these strong exploration results from the Block 6 area as the Company continues to advance along its dual track strategy of continuing its exploration programs while at the same time rapidly advancing Oko West down the development path. The PEA remains on track for release by the end of Q2 2024. On the exploration front, the addition of new datasets is allowing our exploration team to target more effectively within other areas of the Oko West project area. Alongside this, Reunion is continuing to evaluate and define new properties for further exploration in both Guyana and Suriname.”

The Company now has eight diamond drill rigs operating at the Oko West project. Five of these rigs are focused on Blocks 1, 4, 5 & 6 with the dual objective of both adding new resources and the conversion of inferred resources to indicated prior to the commencement of additional studies expected after the completion of the Preliminary Economic Assessment in Q2 2024. Two diamond rigs are carrying out geotechnical and hydrogeological drilling related to potential infrastructure sites on the project.

The eighth diamond rig is focused on drill testing exploration targets outside of the MRE area in search of potential satellite resources. At present this rig is testing targets near to the North Drive area located in the west of the permit; and will shortly move to testing a zone of coincident geochemical and geophysical anomalies in the Takutu zone, immediately south and along strike from the Kairuni resource along the granitoid contact zone. The Company has made significant progress in adding additional geochemical and geophysical data coverage on the project, in particular, through the use of a Scout RC rig to test beneath colluvium and duricrust, as well as the use of gradient array IP and ground magnetics. Figure 2 shows the extent of IP coverage on the project and demonstrates the success with which the results map structural corridors that host alteration and early sulphidation events within Blocks 1 through 4 (as correlated with drill core observations). These corridors have been subsequently used as pathways for gold-bearing fluids and are host rocks to mineralization. The discrete structural corridors that are of particular interest for further exploration and drill plans are underway for two new targets in Blocks 7 and 8.

About Reunion Gold Corporation

Reunion Gold Corporation is a leading gold explorer in the Guiana Shield, South America. In 2020, the Company announced an exciting new greenfield gold discovery at its Oko West project in Guyana and announced its maiden mineral resource in June 2023 after just 22 months of resource definition drilling. In February 2024 the Company announced an updated Mineral Resource Estimate containing a total of 4.3 Moz of gold in Indicated Resources grading 2.05 g/t and 1.6 Moz of gold in Inferred Resources grading 2.59 g/t. The February 2024 Mineral Resource Estimate includes an underground Resource containing 1.1 Moz of gold at a grade of 3.12 g/t Au in the Inferred category. See February 26, 2024 press release for more details. The Company is moving forward on development activities related to Oko West and expects to deliver a PEA by the end of Q2 2024. The Company continues to explore several additional priority targets at Oko West that lie outside of the area of the MRE, as well as leverage its considerable experience in uncovering new discoveries in the Guiana Shield to acquire and explore additional new projects in the region. The Company’s common shares are listed on the TSX Venture Exchange under the symbol ‘RGD’ and trade on the OTCQX under the symbol ‘RGDFF’.
