Ann: Preliminary Pilot Plant Results, page-43

Is my understaning and math correct:
@ 989g/t if they had to process
30 ton of ore to get 1 ton of concentrate that still gives them 33g/t of gold from the ore 137g/t of silver

40 ton of ore to get 1 ton of concentrate that still gives them 24g/t of gold from the ore 103g/t of silver

50 ton of ore to get 1 ton of concentrate that still gives them 19g/t of gold from the ore 82g/t of silver

60 ton of ore to get 1 ton of concentrate that still gives them 16g/t of gold from the ore 68g/t of silver

Pretty good numbers realy but until we get some more details we are only guessing
