"...Weird mix of measurments in the FS though, acres, hectares, total oz of silver and gold, then the silver and gold is produced in grams per tonne. Never noticed it before, I must be Canadian :-)"

If the US is not so stubborn, we would all be metric by now, like the rest of the world! We'll be using grams, KG, metric tonnes, hectares etc! (Although the conversion from acres to hectares would be a bit tricky with all the grids in miles.) Just saying!
