Learning Goals: -What is an ore deposit?

2018-8-7  which will help you to decide where to drill. Copper grade is the concentration of copper in the ore rock. To calculate the grade of copper for the sample, geologists use the equation: (amount of copper metal/amount of copper ore rock)*100 2. If a deposit area has 200lbs of copper in 10,000lbs of ore rock, what is the grade? 200/10000*100=2% 3.
