REUNION GOLD INFILL DRILLING CONTINUES TO EXPAND THE ZONE OF HIGH-GRADE GOLD MINERALIZATION ON BLOCK 6 AT ITS OKO WEST PROJECT, GUYANA

Reunion Gold Corp. has released drill results from its infill drill program on block 6 at its 100-per-cent-owned Oko West project in Guyana. These results, reported in the attached table, 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 ("grams per tonne Au") including 3.8 metres of 14.18 grams per tonne Au and 13.0 metres of 10.50 grams per tonne 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 include:

• Hole D-375 intersecting 60.4 metres of 1.50 grams per tonne Au, including 6.0 metres of 7.06 grams per tonne
• Hole D-381 intersecting 44.9 metres of 2.28 grams per tonne Au, including 18.3 metres of 4.38 grams per tonne Au
• Hole D-389 intersecting 21.6 metres of4.00 grams per tonne Au, including 4.0metres of 17.67 grams per tonne Au

Highlights of drill results reported today include Hole D-375, which intersecting 60.4 m grading 1.50 grams per tonne Au (using a 0.3 grams per tonne cutoff), including 6.0 m grading 7.06 grams per tonne (using a 1.5 grams per tonne cutoff) starting at 31.5 m downhole, Hole D-381 intersecting 44.9 m grading 2.28 grams per tonne Au (using a 0.3 grams per tonne cutoff) starting at 85.2 m downhole, including 18.3 m grading 4.38 grams per tonne Au (using a 1.5 grams per tonne cutoff), as well as Hole D-389, intersecting 21.6 m grading 4.00 grams per tonne Au (using a 0.3 g.t Au cutoff) starting at 150.0 m downhole, including 4.0 m grading 17.67 grams per tonne Au (using a 1.5 grams per tonne 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 grams per tonne and 1.6 Moz of gold in Inferred Resources grading 2.59 grams per tonne. This 2024 MRE includes an underground Resource containing 1.1 Moz of gold at a grade of 3.12 grams per tonne 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. The Company is moving forward on development studies and expects to deliver a Preliminary Economic Assessment by the end of Q2 2024.
