RE:RE:RE:My two CDN pesos worth on the 3Q productionSherry35,
I agree with your number 1 on your list. Based on the last 43-101 report, the 2018 minimum ore grade happened in August 2018, and in 2017 a similar low in ore grade appeared in July of 2017. So I think that they are running the mill on the long term stockpile for one month in summer while everyone seems to be out on holiday.
There are two other explanations to add to your list.
1) Extra heavy summer rains that may have caused flooding in parts of the underground areas.
The average water pumping rate at Bjorkdal is 85.6 cubic meters per hour and the pumps have a capacity of 180 cubic meters per hour. So if there was a storm event with heavy rains, that may be a factor to explain the lower production in Q3.
2) The second possiblity is that high grade ore was mined underground but left in place or hauled to the surface and placed in high grade ore stockpiles in anticipation of higher gold prices.
So with early snows returning to northern Sweden over the past week, I expect #1 to be a non issue for Q4, and if they have high grade stockpiles, I would expect a jump in production for Q4.
