OKO WEST PROJECT

GUYANA

OKO WEST PROJECT 

Reunion Gold’s Oko West Project is located immediately due south of G2 Goldfield’s “Oko” project, which was the subject of an active drill program in 2020. Trenching and drilling programs conducted by Reunion Gold confirmed gold mineralization in shear zones coinciding with gold-in-soil anomalies and geological structures identified from airborne geophysical surveys. The maiden 1,000-meter diamond drilling program completed in January 2021 also confirmed the down-dip extension of mineralized zones discovered by trenching.

Location

 

The Oko West Project is in the Cuyuni Mining District, some 95 km west of Georgetown and easily accessible by laterite roads and trails from the town of Bartica or by boat using the Cuyuni river (Figure 1).

Mineral rights and agreement

The Oko West Project comprises 11,900 acres of mineral rights held by local Guyanese entrepreneurs. Reunion entered into agreements entitling it to conduct exploration activities and acquire a 100% interest in the Project area. 

Geology and mineralisation

The Oko West Project area is underlain by a greenstone belt assemblage of Proterozoic rocks of the Barama Group consisting of volcanics and clastic sediments intruded by granitic plutons, strongly deformed by at least two tectonic events. Gold mineralization discovered so far is preferably focused along north-south trending shear zones at the contact of volcanic and granitoid bodies at the eastern edge of the Project area (Figure 2). The tectonic interaction between these rocks created intense shearing and allowed the introduction of gold mineralization in open spaces, characterized by carbonaceous and sericitic alteration accompanying quartz veining. This gold mineralization has been artisanally mined both in alluvial flats and pits in saprolite material (Figure 3). 

Exploration work

In 2019, Reunion completed geological mapping, a stream sediment sampling of creeks, and a detailed airborne magnetic and radiometric survey. Soil sampling has defined a 6 km-long anomaly coinciding with the geological contact of volcanic and granitoid rocks (Figure 2). During the fourth quarter of 2020, a 19-trench program for a total length of 1,990 meters was completed and 904 channel samples gave very encouraging results (Table 1). Eleven trenches returned sampling intervals with strong gold mineralization (Figure 3), particularly at trenches OKWT20-09 and 18. Significant gold assay results from channel samples include 30 meters at 2.24 g/t (including 8 meters at 5.28 g/t) and 50 meters at 2.04 g/t (including 16 meters at 4.23 g/t) at trench OKWT20-009, in a newly discovered shear zone. A 1,000-meter diamond drilling program completed in January 2021 (Figure 3) confirmed the vertical continuity and geometry of gold mineralization in trenches (Table 2). Drill holes D20-01 and D20-03, for example, drilled under trench T20-09, and drill hole D21-6 near trench 18 confirmed the down-dip continuity of gold mineralization into weathered bedrock and intersected shear structures along intercalated volcanic and granitic rocks (Figures 4 and 5). The near-surface trench channel sampling cut longer mineralized intervals, typical of gold distribution in weathered rocks of equatorial regions, forming a "mushroom" head fed by narrower structures in fresher bedrock.

The Reunion team continues trenching the anomalies defined by soil geochemistry and will subsequently drill gold mineralization discovered by trenches.
