If you seek to significantly expand the mine’s tailings, waste rock, or heap leach facilities, you may have to prepare a new or supplemental EIA.

Introduction Today I went to HR Block and had my taxes calculated. It is a disaster: I owe lots and the total taxes I paid is more than the average Canadian salary. I am seriously considering selling up and moving to Las Vegas. And stopping working. Why work to merely pay great sums to the government [...]
