The lower gold prices will be offset by the lower Canadian dollar and oil prices.
Canadian miners pay their expenses in Canadian dollars but sell gold in US dollars. The high Canadian dollar is one of the reasons that a lot of the Canadian juniors did not go up as much as gold in the past few months.
Energy is about 30% of the cost of most mining.
Base mettals are down too. A big part of the cost of building a new mine.
I doubt the downward trend will continue but if it does it is not as bad as some may think.
The numbers will all have to be reworked for the feasability study.
Some of the assumtions may now be off.
