Decreasing Metal Ore Grades—Is the Fear of Resource

Mt Morgan had a low ore grade (05–1%) compared with the other mines, but a relatively high production share (approximately 20%), which led to a shortterm increase in the average ore grade for these years [8] Another increase in the ore grade was caused by Olympic Dam, which was discovered at the end of the 1970s, and the
