Why is 9.0 m of 12.21 g/t Au at 320 m vertical depth important?

Question

Accepted Answer

The 9.0 m of 12.21 g/t Au at 320 m vertical depth matters because it shows high-grade gold mineralisation continues at depth at Upper Antino

Drill hole FR230 intersected 9.0 m grading 12.21 g/t gold from 408.0 m down-hole, which the company describes as approximately 320 m vertical depth. This is important because it supports the idea that the Upper Antino gold system is not just near-surface, but remains high-grade deeper in the ground. The same hole also returned 37.0 m grading 3.27 g/t Au from 209.0 m, reinforcing a broader depth interval of gold mineralisation.
It provides direct evidence of grade continuity into deeper levels
The specific FR230 result—9.0 m at 12.21 g/t Au starting from 320 m vertical depth—indicates that higher-grade gold is present at depth rather than being limited to shallow drilling. The release also links this deeper intercept to multiple gold-bearing zones within the same hole, including 37.0 m at 3.27 g/t Au from 209.0 m. In exploration terms, continuity of grade from surface downwards is a key observation when defining whether a mineralised system extends vertically.
It supports the company’s plan to focus on resource-definition and infill drilling
The company is concentrating its Upper Antino drilling metres where site access remains strongest, specifically on resource-definition and infill drilling across the established core of the system. A deeper high-grade intercept like the 9.0 m at 12.21 g/t Au helps justify that focus, because it shows the “core” includes significant gold at depth. At the same time, the company continues to test growth to depth, which is consistent with having both shallow and deeper high-grade results at Upper Antino.
It aligns with how large Guiana Shield gold deposits can behave at depth
The Guiana Shield, where the Antino Gold Project is located in southeastern Suriname, contains several large gold deposits that carry significant gold at depth. The Upper Antino results are described as matching that same potential, with the FR230 deeper intercept forming part of the evidence. This regional context matters because it frames the expectation that meaningful gold grades can persist below the surface in Guiana Shield systems.
It is part of a broader pattern of mineralisation across multiple depths
FR230 did not deliver only one isolated high-grade interval; the release lists additional gold intercepts in the same hole, including 3.0 m of 5.53 g/t Au and 2.0 m of 7.21 g/t Au. The company also reports shallow mineralisation on a main shear that links the near-surface zone to the deeper high-grade intercepts, reinforcing the overall continuity picture. Together, these results show that gold mineralisation at Upper Antino is distributed across a range of depths rather than confined to a single thin horizon.
