GOLD: It is usually reported in grams per tonne (or g/t), although sometimes, in the US, it is in oz/ton. A gram of gold is worth about $25, so 2 grams or better would be viewed as high-grade for bulk tonnage mining. One hundred metres of good grade is again good criteria for thickness.

However, this extreme grade and thickness only comes along once every 10 years or so
