Mullins — the reported 461 g/t Au (with a range of 86.8–461 g/t and an average of 187 g/t) are unquestionably strong numbers. However, it’s important to be precise about what they represent.
These grades are from concentrate, not from in situ ore. The material has already been upgraded through gravity-based processing (e.g., Knelson circuits), resulting in a smaller, enriched fraction of gold. Thus, 461 g/t does not imply 461 g/t head-grade ore underground.
That said, the results are still significant. They confirm the presence of coarse, gravity-recoverable gold — which is positive for processing costs and supports the potential for selective underground mining, particularly in a historic narrow-vein system like Clogau-St David’s.
At current gold prices (~$4,900/oz ≈ , $157/g), the gross metal value per tonne of concentrate would approximate:
• 187 g/t ≈ $29,000 per tonne
• 461 g/t ≈ $72,000 per tonne
But viability ultimately hinges on:
• Head grade going into the plant
• Recovery rates
• Tonnage continuity
• Mining cost per tonne
• Sustainable production scale
High-grade concentrations are encouraging, but the real economic question lies in orebody geometry, consistency, and extractable tonnage.
In short: technically impressive numbers, commercially dependent on scale and continuity.
