Ann: Trucking of Ore Commences at Baal Gammon Min, page-2

re: Ann: Trucking of Ore Commences at Baal Ga... OK, all good news in my opinion, but no dollar figure on the royalties, so maybe someone out there could help with the figures.
They should get 3% ore out of each ton mined and trucked, so thats 30 kg of ore each tonne.
Also they should get at least 30 grams of silver per tonne.
So if we can find these prices and then take 2.5% royalty out, then multiply by 550,000, that should give us a rough royalty figure for the first 550,000 tonnes.
Any one out there care to add to this or correct it, i dont have the ore or silver prices yet.
