This is a guide to how much gold is needed in an underground mine per tonne. Anything with an average over 5 grams is good.
Low grade 0 - 5 gold grams per tonne
Average grade 5 - 8 gold grams per tonne
High grade 8 + gold grams per tonne
'Bonanza' grade Troy Ounces (31.1 grams) per tonne

A 2012 report conducted by Snowdon Mining Consultants on behalf of the previous majority owners of the mine, Gold Mining Wales Ltd (GMW), suggested that as much as 500,000 ounces of gold could be lying untouched in the area surrounding the mine,[4] giving hope that gold may again be extracted from the Clogau Gold Mine. Alba Mineral Resources are now the majority owner of the mine and are currently drilling to assess the commercial viability of reopening parts of the mine. Previous samples taken from a 200 metre long area returned gold grades of 30.2 to 263 grams per tonne,[5] suggesting that previously unrealised supplies of gold could potentially exist.
