Many investors new to the sector ask: what is a “good” gold grade?
Unfortunately, there isn’t one universal answer.
Let’s use 1.0 g/t Au as an example.
That means one gram of gold per metric tonne of rock, or approximately one part per million by mass.
As the g/t increases, so does the amount of gold contained in each tonne of rock. Higher grades can improve economic potential, but grade alone does not determine whether a deposit is economic.
The chart below shows broad illustrative grade ranges for open-pit and underground settings, but they are not universal cut-off grades.
For a large, shallow open-pit system, 1.0 g/t Au may be meaningful.
Real-world examples include:
→ Detour Lake, Canada: 0.75 g/t Au in its open-pit Proven and Probable Mineral Reserve as of December 31, 2024.
→ Tocantinzinho, Brazil: 1.17 g/t Au in its Proven and Probable Mineral Reserve as of December 31, 2025.
For many underground gold operations, 1.0 g/t Au would generally be considered lower grade.
What matters is the broader context, including mining method, width, continuity, recovery, scale and costs.
That is why investors should look beyond the headline grade.
