• True widths are unknown.
• Composites calculated using these parameters:
  • Minimum composite grade : 0.4 g/t; minimum composite length : 2 m
  • Cut-off of an interval to be included in composite: 0.4 g/t  
  • The maximum length of internal waste: 2 m.
  • Gold grades are uncapped.

The Company has now drilled a total of 4,864 meters in 42 DD holes and 4,842 meters in 62 RC holes since the beginning of the drilling program at Oko West in December 2020. All significant assay results have now been reported.

Carlos Bertoni, the interim CEO of the Company, stated: “We continue to receive impressive assay results from the drilling campaign at Oko West. Several drill holes confirmed down-dip continuity of gold mineralization in unweathered rocks down to a depth of 150 meters. The overall mineralized footprint has been expanded to 850 meters in strike length and remains open at depth and on strike. We plan to conduct a follow-up drilling program starting in mid-October of approximately 9,000 meters using two diamond drill rigs and one reverse circulation drill rig to further define the gold mineralization footprint and continue discovering new mineralized zones."

The drilling campaign is testing the vertical and lateral continuity of trench gold anomalies previously identified in eight mineralized "blocks" straddling mineralized north-south shear zones over a 3 km long strike length (Figure 1). Mineralized intersections are characterized by zones of intense hydrothermal alteration (carbonate, sericite, pyrite, silica) in sheared clastic sediments, granitoids, and mafic volcanics with disseminated gold containing metric-scale high-grade veins assaying up to several ounces per tonne.

Oko West is part of a group of permits in the Cuyuni River basin covering an area of approximately 10,880 acres where the Company has an option to acquire a 100% ownership interest.

Sample collection, assaying and data management

Diamond drill samples consist of half of either HQ or NQ core taken continuously at regular intervals averaging 1.4 m, bagged, and labeled at the site core shed. Reverse circulation drill samples are obtained from a rotary splitter attached to a Metzke cyclone, weighed, bagged, and labeled 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 the proportion of 5% of samples shipped to the laboratory. Assay data is subject to QA/QC using acQuire software and management by an independent consultant.
