OKO MAIN
The 19,200-acre Oko project is located in the southeastern portion of the Cuyuni Mining District, approximately 120 km west-southwest of Guyana’s capital city, Georgetown, 60 km west of the town of Bartica, and directly north of Reunion Gold’s Oko West project. The project is accessed by a combination of boat and truck, using rivers and logging roads, from the town of Bartica and the Itaballi crossing on the Mazaruni River.
The project covers approximately 7,149 ha of land, coving 17 km of prospective strike length. Five discrete, multi-kilometer long zones of gold mineralization have been delineated by soil sampling and mapping of historical and current artisanal mining operations. Despite a long history of production, the Oko property had never been previously drilled or subjected to a modern exploration program.
To date, G2 Goldfields has drilled 116 (for +28,808 metres) holes within the Oko Zone, 18 holes at Aremu, 4 holes at NW Oko, and 2 holes at Tracy. The project is currently under multiple option agreements with local Guyanese mid-scale miners that entitles G2 Goldfields to conduct exploration activities and acquire a 100% interest in the project.
The Oko project area is located in the Cuyuni greenstone belt, which is part of the Baram-Mazaruni Supergroup (2,200-2,100 Ma) and the highly underexplored Guiana Shield. The property is host to high grade orogenic gold mineralization within the Cuyuni Basin Sediments and the underlying Barama volcanics. To date, mineralization is found within fold hinges, parallel shear zones, and breccias along lithological contacts within a sequence of metamorphosed carbonaceous sediments and volcanics.
1. OKO N.W.
Current Target – Drill Program Underway
The NW Oko trend is a 3 km long zone of artisanal workings and anomalous gold in soils, that intersects the Oko Main Zone at its northern extent.
“Mineralization encountered at NW Oko highlights the potential for large, disseminated, low-grade deposits to be hosted alongside, or intersected by, high-grade vein systems within the Oko–Aremu Gold District”.
-Dan Noone, CEO
2. TRACY
The Tracy target, located 10 km northwest of Oko Main and 3 km southeast of the Aremu Mine Area, is defined by a 2.5 km long (east west trending) gold-in-soil anomaly (+ 100 ppb Au). In 1992, Golden Star Resources completed a trench at Tracy which intersected 10.7 g/t Au over 15 m. G2 completed more than 6 trenches totalling 608 m located several hundred metres east of the Golden Star trenching. G2 has intersected highly encouraging results, including 4.8 g/t Au over 16 m with a high-grade section of 32.4 g/t Au over 2 m. Two initial holes were drilled beneath the trench which intercepted low grade mineralization hosted within metamorphosed sandstones and siltstones. Further geological modelling is being completed to determine best next steps for Tracy.
“Initial trenching at Tracy has exposed high grade gold mineralisation in deformed carbonaceous mudstones and siltstones within broader zones of hydrothermal alteration, similar to what we see at the Oko Main Zone.”

3. AREMU MINE AREA
Between 1906 and 1911, more than 20 auriferous veins were discovered within the Aremu Mine Area which produced approximately 6,488 oz Au during this period.
The high-grade gold mineralization is located mainly in the brecciated quartz-carbonate veins with hematite staining and pyrite. Low-grade gold is hosted in black graphite schist with quartz veinlets and stringers. During the historical exploration, the following gold-bearing veins were identified: the Aremu, Donicker, Herod, Hillman, Powerhouse, Shepherd, as well as the Honeybee, Lunch, Maam and Powis veins.
G2 has been trenching and collecting numerous soil samples, grab samples, and channel samples along the previously mined open-pits. G2 followed up this program with an 18-hole drill campaign totalling 2,436 m that drill tested the historic Aremu, Donicker, Scotland, Powerhouse, and Lunch veins. Significant intervals include hole ARD-03 which was drilled beneath the historic Aremu open-pit and intersected 10.7 g/t Au over 3.4 m within a broader zone of 3.6g g/t Au over 13.5 m. The high-grade gold mineralization is hosted in quartz veins within a shear zone in carbonaceous shales in a northeast plunging fold closure. Drilling in 2022 will continue to explore the main shaft area where drill hole ARD-03 returned multiple gold intercepts.
4. GHANIE
The Ghannie target spans a strike length of approximately 700 meters and is located between the OKO Main Zone and Reunion Gold’s Block 4 Discovery.
In 2019, G2 entered into an option agreement to acquire a 100% interest in the four Ghanie claims, totaling 3,280 acres, which are contiguous to the southeastern extent of the Oko claims. In mid-2020, the Company undertook an initial geological mapping and reconnaissance drill program just to the south of the Oko Main zone deposit. Significant intersects include: 8.0 g/t Au over 1 m, 7.6 g/t Au over 2.6 m and 10.9 g/t Au over 0.4 m (OKD – 37) as well as 1.6 g/t Au over 12 m (OKD – 39).
5. OKO EAST
- Quartz vein containing visible gold exposed in Carbonaceous sediments, similar to Oko.
- Two high-grade grab samples of quartz vein floats.
- Early-stage prospect which has excellent growth potential
“Exposure of quartz boulder float and an outcropping quartz vein, host visible gold mineralization in carbonaceous sediments similar to the Oko Main area. Two grab samples on cobble-sized floats of the quartz vein returned 31.4 g/t Au and 9.4 g/t Au close to an area with extensive artisanal workings. We believe that Oko East is an early-stage target which has excellent upside potential for the discovery of additional economic mineralization in the Oko district”
