O2Gold Inc. announced that the latest results from its ongoing drill program confirm the mineralized system of the main Aurora vein located at its property in Colombia at depth. Holes AUR-21-002 and AUR-21-003 both targeted the main Aurora vein. The intercept from AUR-21-002, which was 18m from the surface, confirms the high-grade gold result seen in the Company’s first drill hole. Figure 1 shows the mineralized interval with portions of quartz veins intercalated in mylonitic and porphyroblastic rocks altered by weathering. AUR-21-003 intercepted approximately 150 meters from the surface. The intercept was between 159.20 to 163.20 meters, totaling 4.00 meters of apparent thickness, with weighted average grades of 0.71 g/t Au and 5.09 g/t Ag. The richest interval occurs between 159.20 and 160.40 meters, totaling 1.20 meters of apparent thickness and grades of 1.71 g/t Au and 14.20 g/t Ag. The intercepted interval confirms the mineralization seen in holes AUR-21-001 and AUR-21-002 and shows the extent of the vein at the projected down dip. Following the Company’s report of an intercept with 20.11 g/t Au, these results show that more drilling is needed to understand average values for the main Aurora vein’s width and grade. When the Aurora mine begins small-scale production, a large volume sample will be important for this definition and additional forthcoming drill results are expected to reveal its minimum extension. In addition to the five indicated or observed veins near the Aurora tunnel, the Company’s ongoing rock channel sampling, geophysics, and mapping of the other brownfield targets has yielded many more areas of interest that need to be confirmed with drilling. In Aparecida, five veins have been indicated, with average projected extensions of at least 300m. The anastomosed pattern is characterized by the opening and closing of the mineralized structures. Aparecida’s Fortaleza vein has a projected extension of at least 400m, and rock channel sampling returned maximum values of 42.3 g/t Au and 49.6 g/t Ag. In Quintanillo, which is directly south of the Aurora area, four distinct veins have been indicated, with the primary vein projected to have an extension of at least 1.2km. Finally, in Botella, five distinct veins have been observed or indicated, with an average projected extension of at least 200m. The Esmeralda vein has an observed width of 1m, and several rock channel samples showed grades of more than 30 g/t Au. All samples were shipped to SGS Colombia S.A.S. (“SGS”)’s lab facility in Medellin, Colombia, where they were prepared and analyzed. They were analyzed using SGS procedure FAA515 to gold (fire-assay on a 50-gram sample with AAS finish) and AAS12C to silver (multi-acid digestion with AAS finish). Over the limit gold was determined by SGS procedure FAG505 (using standard fire-assay on a 50-gram sample with a gravimetric finish). In line with QAQC best practices, approximately 10% of a 78-sample batch are control samples (three Au-Ag standards: High/Medium/Low grades, two fine blanks, one project blank, and two field duplicates).
