Reunion Gold (TSXV:RGD) has announced additional positive drill results from its Oko West gold project in Guyana. The latest results come from both resource expansion drilling below the existing deposit and infill drilling within areas of inferred resources.
Rick Howes, President and CEO of Reunion Gold, commented in a press release: “I am very pleased with the results of both the resource conversion and the resource expansion drill programs, which together continue to confirm the strong levels of continuity within the open pit resource as well as the expansion of high-grade mineralization below the previously defined MRE pit shell, down to depth of 1,000 m where it remains open. This also confirms that we have significant underground potential below what is already very significant open pit potential. Once the open pit resource model is updated and the new underground resource model is complete, both the open pit and underground mine design scenarios will be evaluated as part of the Preliminary Economic Assessment (“PEA”) work already underway with G Mining Services. This work will also determine the transition depth from the open pit to underground as well as the preferred sequencing of the open pit and underground mine. We expect to release the PEA before the end of June 2024. Permitting also continues on schedule with baseline studies nearing completion and Terms of Reference for the Environmental Impact Assessment submitted to the Guyana Environmental Protection Agency for approval.”
The expansion drilling continues to confirm high-grade gold mineralization within Block 4 of the Kairuni zone, extending over 1,000 meters down-dip beyond the limits of the June 2023 mineral resource estimate (MRE) pit shell. Highlights include 14.3 meters at 8.84 g/t gold and 10.5 meters at 6.09 g/t gold within 50.1 meters at 4.10 g/t gold in hole D-360A-W2 from 1039.8 meters depth. Hole D-359-W1 intersected 24.4 meters at 7.80 g/t gold and 4.2 meters at 4.02 g/t gold within 83.5 meters at 3.06 g/t gold from 721.5 meters depth. Hole D-362A intersected 15.5 meters at 4.26 g/t gold, 4.9 meters at 6.29 g/t gold and 4.3 meters at 6.64 g/t gold within 76.0 meters at 2.27 g/t gold from 991.0 meters depth. The high-grade zone remains open at depth below 1,000 meters.
Approximately 23,500 meters of drilling below the June 2023 MRE pit will be incorporated into an updated resource estimate. Reunion Gold has also commenced a 20,000-meter infill drill program targeting deeper mineralization to upgrade resources to an indicated classification before starting a feasibility study in Q3 2024.
The infill drilling program continues to confirm continuity of mineralization and higher grades at depth within the existing MRE pit shell. Highlights include 65.9 meters at 5.12 g/t gold in hole D-353A, including 15.5 meters at 13.52 g/t gold and 8.3 meters at 4.61 g/t gold. Hole D-366 intersected 45.0 meters at 1.85 g/t gold, including 7.3 meters at 2.52 g/t gold and 4.2 meters at 3.12 g/t gold.
The updated MRE will include an open pit and an initial underground resource estimate. It will feed into a preliminary economic assessment expected by the end of June 2024.
Exploration drilling outside the MRE area has yielded several zones of anomalous gold, providing targets for further drilling. Geophysical surveys are also underway to identify additional targets across the Oko West project area. Reunion Gold plans to acquire and explore new projects in Guyana and Suriname to build its portfolio in the Guiana Shield region.

Reunion Gold’s (TSXV:RGD) Oko West gold project in Guyana continues to report further drill results, revealing both the extension of high-grade mineralization at depth and the strong consistency of the deposit within the established Mineral Resource Estimate (MRE) pit shell.
Rick Howes, President and CEO of Reunion Gold, commented in a press release: “We are pleased with the results of the deep drill program which continues to indicate that the high-grade zone that was identified within the MRE in Block 4, continues to a depth of at least 1000 meters and is open below that. We expect this resource expansion drill program to be completed early in 2024 and those results will be included in the resource. The resource will include both an updated pit constrained resource in the area above 500 m and an initial resource in the area down to a 1,000-meter depth. We remain on track to release a Preliminary Economic Assessment (“PEA”) in Q2/24, which will include this resource update and investigate the potential for a combined open pit and underground mining operation. We also continue to explore other areas of the Oko West prospecting license for potential satellite deposits.”
Deep Drilling Uncovers Significant High-Grade Intercepts
Drilling below the MRE pit shell delivered several notable results, highlighting the potential for resource expansion at greater depths. Hole D-336 intersected a remarkable 33 meters grading 7.26 g/t Au within a broader interval of 78.2 meters averaging 3.45 g/t Au, pushing high-grade mineralization down to approximately 805 meters. Hole D-346A-W1 further bolstered this excitement, encountering 13.0 meters of 8.41 g/t Au and 12.3 meters of 10.36 g/t Au within a broader 82.6-meter interval averaging 3.7 g/t Au, reaching a depth of approximately 820 meters. These are just two examples of the numerous high-grade intercepts reported across the deep drilling program, suggesting significant potential for further resource growth beyond the current MRE.
Resource Conversion Drilling Confirms Deposit Continuity Within Pit Shell
Drilling within the MRE pit shell also delivered positive results, confirming the strong continuity and consistency of the deposit within the planned mining area. Hole D-343 intersected a substantial 110.6 meters grading 2.77 g/t Au, while Hole D-340 returned an impressive 105.1 meters averaging 2.15 g/t Au. Holes D-335 and D-339 also contributed significant intercepts, further solidifying the confidence in the deposit’s continuity and potential within the established pit shell.
Development Studies Progressing Steadily
Reunion Gold is actively advancing several development-related initiatives at Oko West. Environmental and social baseline studies have been completed, with the second phase fieldwork finalized. The Environmental Permit application has been submitted to the relevant authorities, marking a crucial step in the permitting process. Terms of Reference for the comprehensive Environmental and Social Impact Assessment (ESIA) are expected to be finalized in Q4 2024.
Team Bolstered by New Country Manager Appointment
Further strengthening their commitment to Oko West’s development, Reunion Gold welcomes Bjorn Jeune as their Country Manager for Guyana. Bjorn brings extensive experience in the mining industry, particularly within Guyana, and will play a key role in overseeing the permitting process, public affairs, and community engagement initiatives.
Looking Ahead
With ongoing exploration success at depth and within the planned pit area, coupled with consistent progress on development studies and team expansion, Reunion Gold’s Oko West project continues to demonstrate immense potential. The coming months promise further exciting developments as the ESIA progresses and permitting discussions advance, paving the way for the project’s future success.
