Highlights include:

• Hole D-375 intersecting 60.4 m @ 1.50 g/t Au, including 6.0 m @ 7.06 g/t
• Hole D-381 intersecting 44.9 m @ 2.28 g/t Au, including 18.3 m @ 4.38 g/t Au
• Hole D-389 intersecting 21.6 m @4.00 g/t Au, including 4.0m @ 17.67 g/t Au
  

LONGUEUIL, April 15, 2024 - Reunion Gold Corp. (TSXV: RGD; OTCQX: RGDFF) (the "Company") is pleased to announce additional drill results from its infill drill program on Block 6 at its 100%-owned Oko West Project in Guyana. These results, reported in Table 1 and illustrated in Figure 1, continue to expand the core of high-grade mineralization that has been identified at Block 6 and are consistent with the results of the previously released hole D-380, which intersected 39.7 meters ("m") at 5.27 grams per tonne of gold ("g/t Au") including 3.8 m @ 14.18 g/t Au and 13.0 m @ 10.50 g/t Au. Rick Howes, CEO of Reunion Gold, stated, "We are pleased to see the identification of further high-grade mineralized shoots at Oko West, resulting from the exploration team's growing understanding of structural controls and the factors that are localizing mineralization along the Kartuni shear zone. These latest results continue to indicate the potential for additional high-grade gold mineralization to be defined even within areas of existing wider drill spacing as our current infill program continues."

Highlights of drill results reported today include Hole D-375, which intersecting 60.4 m grading 1.50 g/t Au (using a 0.3 g/t cutoff), including 6.0 m grading 7.06 g/t (using a 1.5 g/t cutoff) starting at 31.5 m downhole, Hole D-381 intersecting 44.9 m grading 2.28 g/t Au (using a 0.3 g/t cutoff) starting at 85.2 m downhole, including 18.3 m grading 4.38 g/t Au (using a 1.5 g/t cutoff), as well as Hole D-389, intersecting 21.6 m grading 4.00 g/t Au (using a 0.3 g.t Au cutoff) starting at 150.0 m downhole, including 4.0 m grading 17.67 g/t Au (using a 1.5 g/t cutoff).

The Company continues to conduct its drill program designed to both expand and infill the Oko West resource, as well as to advance its exploration programs to identify additional areas of mineralization outside of the resource area at Oko West. In parallel with this, the Company continues to move its development studies forward, with the near-term goal of releasing a Preliminary Economic Assessment by the end of Q2 2024.

In February 2024, the Company announced an updated Mineral Resource Estimate (the "2024 MRE") 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. This 2024 MRE includes an underground Resource containing 1.1 Moz of gold at a grade of 3.12 g/t Au in the Inferred category. See the Company's NI 43-101 Technical Report Oko West Gold Project, Cuyuni-Mazaruni Mining Districts, Guyana dated April 11, 2024, with an effective date of February 26, 2024 for additional information about the Oko West Project and the 2024 MRE.
