Reunion Gold reports new drill results at its Oko West Project in Guyana including 2.44 g/t over 46.5 m, 2.22 g/t over 57.0 m and 1.88 g/t over 41.0 m
The objective of the current drill campaign is to confirm the vertical and lateral continuity of gold mineralization previously identified in eight "blocks" straddling shear zones over a 3 km long strike length, within a 6 km long soil geochemical anomaly. Diamond drilling ("DD") has been focused on testing depth extensions into the unweathered rock below 100 m (Figure 2), as well as testing for lateral extensions between the outlined blocks. The reverse circulation ("RC") rig is testing the edges of exploration blocks and scouting previously untested targets both laterally and along strike. The Company has so far demonstrated continuous gold mineralization in a "corridor" more than 1.2 km long (see Figures 1 and 3) characterized by zones of intense deformation and hydrothermal alteration in sedimentary, granitic, and volcanic rocks. These zones contain widely disseminated gold in microfractures and metric-scale high-grade veins assaying up to several ounces per tonne.
Carlos Bertoni, Interim CEO, stated: "We are very excited by this round of drill results as they continue to demonstrate the impressive continuity of the gold mineralization outlined to date with long intercepts of good grade. The results successfully expand the known deposit both at depth into the unweathered rock, and laterally, between the previously outlined "blocks." The deposit remains open to expansion in all directions. We have only started drill testing the southern 3 km of the soil geochemical anomalies."
The Company restarted its drilling activities at the Oko West Project early in November, following a one-month break to finalize the interpretation of the then recent results and to properly plan the current 9,000-meter drill program, and for equipment maintenance. Assay results presented in Table 1 below shows significant intersections from a total of 1,322 meters in eight DD and 834 meters in nine RC holes, with assay results from two DD holes and ten RC holes not yet received.

The Company has now drilled a total of 6,467 meters in 53 DD holes and 7,836 meters in 91 RC holes since the beginning of the drilling program at Oko West in December 2020, with significant assay results reported in press releases on August 12, September 7, and October 7, 2021. The Company will interrupt its field activities at the Oko West Project from December 17, 2021, and restart early in January 2022 and plans to complete this current drill campaign by the end of March 2022.
Metallurgical testing
The Company completed a maiden scoping-level metallurgical test by bottle-roll cyanide leaching eight mineralized samples at the Actlabs laboratory in Georgetown, Guyana. These samples represent weathered and unweathered rocks from trench and drill hole samples in different host rocks. Positive gold recovery results were received using low cyanide (0.5 kg/t) in under 12 hours of leaching. Gold recoveries range between 78% and 98%. These preliminary encouraging results indicate that gravity concentration followed by cyanidation should improve gold recoveries. The Company is preparing a complete metallurgical testing plan for the Oko West mineralized rocks.
Drill result composites, sample collection, assaying and data management
The Company calculates drill results composites with a minimum length of 2 m, a cut-off grade of 0.3 g/t and 2 m maximum length of internal waste. Gold grades are uncapped. True widths are unknown. Complete drilling results and drill hole data are being posted on the Company's website. Diamond drill 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 drill samples are obtained from a rotary splitter attached to a Metzke cyclone, weighed, bagged, and tagged at the drill site. Samples are shipped to the Actlabs certified laboratory in Georgetown, Guyana, respecting the best chain of custody practices. At the laboratory, samples are dried, crushed up to 80% passing 2 mm, riffle split (250 g), and pulverized to 95% passing 105 μm, including cleaner sand. 50 g of pulverized material is fire assayed by atomic absorption (AA). Initial assays with results above 3,000 ppb gold are re-assayed with a gravimetric finish. Certified reference materials and blanks are inserted at 5% of samples shipped to the laboratory. Assay data is subject to QA/QC using acQuire software and management by an independent consultant.
