RGD Reunion Gold Corp

Reunion Gold Corporation (TSXV: RGD; OTCQX: RGDFF) (the “Company” or “Reunion Gold”) is pleased to announce an update on its ongoing expansion and infill drill programs at Oko West, Guyana and provides a corporate update including the acquisition of mineral interests adjacent to Oko West and in Suriname.

Oko West Drill Program

Resource and exploration drilling continues at Oko West with four diamond drill rigs, focused on infill and expansion drill programs on Block 4, below 640 meters (m) depth, as well as on Blocks 5 and 6. Results from all of the released drillholes program are detailed in Table 1 and Table 2, and shown on a long section in Figure 1.

Highlights from the deep drilling in Block 4 include hole D-393A-W2 which intersected 107.0 m grading 2.42 grams per tonne of gold (“g/t Au”) from 660.0 m downhole (using a cutoff grade of 0.3 g/t Au), including 20.0 m grading 9.78 g/t Au from 734 m downhole (using a 1.5 g/t Au cutoff). Additional highlights include hole D-316-W1 intersecting 101.0 m grading 2.69 g/t Au from 694.0 m downhole (using a 0.3 g/t cutoff) including 13.1 m grading 7.84 g/t Au from 758.9 m downhole (using a 1.5 g/t Au cutoff) and hole D-347-W4 which intersected 108.7 m grading 1.39 g/t Au from 932.0 m downhole (using a 0.3 g/t Au cutoff) including 4.9 m grading 5.11 g/t Au from 991.4 m downhole (using a 1.5 g/t cutoff). In addition, hole D-398 drilled in Block 5 returned 34.8 m grading 3.02 g/t Au from 159.4 m downhole (using a 0.3 g/t Au cutoff) including 6.9 m grading 11.48 g/t Au (using a 1.5 g/t Au cutoff) from 159.4 m downhole.

Rick Howes, President and CEO of Reunion Gold, stated: “The results of the drill program at Block 4 continue to illustrate the continuity and consistency of the gold mineralization at depth in Block 4, including the presence of the high-grade zones both at depth and within newer zones being identified in Blocks 5 and 6.”

Short-term drill plans at Oko West will continue with (i) the targeting of high-grade zones below Blocks 5 and 6, (ii) a 12-hole 20 m spaced drilling program to further add support to the short-range variography in support of planned study activities, and (iii) exploration drilling that includes drilling within and to the west of Block 8 in follow up to recently defined geochemical and geophysical anomalies.

Extension to the Oko West Project

The Company has entered into an option agreement entitling the Company to explore and acquire an additional 1,530 hectares of land, adjacent to the northwest corner of the Oko West prospecting license boundary (see Figure 2). The option agreement is valid for a period of five years and may be extended for two additional years.

Soil geochemical surveys undertaken on this new area indicate several areas of anomalous gold results that also align with recently acquired gradient array IP anomalies. Integration of these results, and the delineation of drill targets is underway with additional geologic mapping, as well as trench and channel sampling.

Majorodam Project, Suriname

The Company has entered into an option agreement to acquire the Majorodam Project in Suriname, which comprises a right of exploitation for gold over an area totaling 99.85 square kilometers (~ 10,000 hectares) The project is located along a paved road 120 km south of Paramaribo, the capital city of Suriname and “on trend” about 12 km south of the 1.02 Moz @ 2.2 g/t Au Saramacca deposit owned by Zijin Mining.

The Majorodam project is prospective for an orogenic gold system and has a similar geologic setting to that of Oko West. Except for airborne geophysics and surface mapping and limited geochemical sampling, there has been little modern exploration work completed at Majorodam. The project area covers the NE trending contact between granitic and volcanic rock units, with the latter unit creating a prominent topographic high. The airborne magnetic survey indicates the presence of several significant NE trending structures in the project area (see Figure 3) and active alluvial gold mining is occurring in the streams draining the main topographic ridge comprised of greenstone altered volcanic units.

The option agreement is valid for an initial period of six years and requires the Company to make option payments of US$150,000 following execution of the agreement and US$75,000 on each of the second, third, fourth and fifth anniversary, and to incur minimum exploration expenditures starting with US$200,000 during each of the first two years.

It is expected that this project will be transferred to Greenheart Gold Inc. (referred to as “SpinCo” in the April 22, 2024 announcement) in connection with the proposed business combination between Reunion Gold and G Mining Ventures Corp. (“G Mining”) announced on April 22, 2024 (see the joint Reunion Gold and G Mining news release issued on April 22, 2024).

French Guiana

The Company has decided to permanently cease its activities in French Guiana due to the unfavorable conditions currently prevailing in French Guiana for pursuing mineral exploration and development projects. A notice of termination of the option agreements for both the Boulanger and Dorlin projects in French Guiana was sent to the titleholders. The termination of the option agreements will be effective on June 24, 2024 and August 10, 2024 respectively.

Sample Collection, Assaying and Data Management

Significant intervals in this press release have been calculated using a grade cut-off of 0.3 g/t Au, a minimum length of ten meters, and a maximum length of ten meters of consecutive internal waste. Included significant intervals have been calculated using a grade cut-off of 1.5 g/t Au, a minimum length of three meters, and a maximum length of three meters of consecutive internal waste. Gold grades are uncapped. Mineralized intersection lengths are not necessarily true widths and estimated true thickness (“ETT”) has been calculated using an assumed plane of mineralization dipping 65° towards 095°, representative of the mineralization identified in Block 4. Complete drilling results and drill hole data are posted on the Company's website. Diamond drill (DD) samples consist of half of either HQ or NQ core taken continuously at regular intervals averaging 1.4 m, bagged, and labelled at the site core shed. Reverse circulation (RC) drill samples are obtained from a rotary splitter attached to a Metzke cyclone, weighed, bagged, and tagged at the drill site. All resource drilling samples are shipped to the Actlabs certified laboratory in Georgetown, Guyana, respecting best-practice chain of custody procedures. Samples from the Scout RC program and recent conventional RC samples are shipped to the MS Analytical laboratory in Georgetown using the same chain-of-custody procedures. At each laboratory, samples are dried, crushed to 80% passing 2 mm, riffle split (250 g), and pulverized to 95% passing 105 μm. Coarse blanks are inserted by the Company, and are used between and following suspected high-grade intervals. Barren sand flushes are inserted by the analytical laboratory after each sample is pulverized to clean the bowl. Gold analysis is carried out through a 50 g fire assay with an atomic absorption finish. Initial assays with results above 3.0 g/t Au are re-assayed with a gravimetric finish. Samples with visible gold are additionally assayed with a metallic screen method using 1 kg of pulp. Certified reference materials and blanks are inserted at a rate of 5% of samples shipped to the laboratories. RC field duplicates and DD umpire pulp duplicates are also generated at a rate of 5% of samples. Pulp umpire duplicates are analyzed at the MS Analytical certified laboratory in Georgetown. Assay data is subject to QA/QC prior to accepting into the Company database managed by an independent consultant.
