The most interesting part of this announcement is the tonnage to be milled, which will be 35,000 to 50,000 tons of ore every three months. Depending on grade, this could yield from (at a guess) 40,000 to 150,000 grams of gold every three month. Low figure would be for 35k tons of ore at a bit over 1gm/ton, and the high figure for 50k tons at around 3gm/ton. My best guesstimate would be somewhere between those numbers, likely around 80,000 grams every 3 months, which is slightly more than 2,800 ozs.
