Going back to the hedging ann gives an indication.

"The Company took advantage of 10 year highs in the silver price to sell forward 558,000 ounces at an effective price of A$26.04 per ounce. This represents a 33% price improvement to the $19.54 per ounce silver price assumed in the Definitive Feasibility Study for the Fossey mine development. The quantity of silver sold forward equates to 27% of the payable silver planned to be recovered to concentrates and sold from the Fossey deposit."

If 558k ounces is 27% of the payable silver planned from Fossey (2 years) then that means 2.066 ounces are the planned payable total.

So 1m oz delivered per year.

That leaves 73% to be paid at spot price presumably.
