What counts as a good gold drill intercept?

"Good" depends on deposit type, depth, and mining method, so treat thresholds as screens, not rules:

• Bonanza grade: above ~30 g/t gold over meaningful width — rare, headline-grabbing.
• High grade: roughly 5–30 g/t, typical of underground-mineable veins.
• Moderate / open-pittable: ~1–5 g/t; large tonnages at these grades can be very economic at surface.
• Low grade: below ~1 g/t can still work in bulk-tonnage, low-strip open pits.

Width matters as much as grade. 1 m at 20 g/t (20 gram-metres) is often less valuable than 40 m at 1.5 g/t (60 g·m). Depth matters too: a high-grade hit 800 m down is costlier to mine than the same hit at surface. And one hole proves nothing on its own — a good result is one that extends or confirms continuity across a deposit. Use the drill calculator to convert any intercept to gram-metres and value-per-tonne.
