Download. This is the common design used by most people who like compact mining layouts. But it can be improved! Coverage is simply the percent of the total space that is covered by mining drills. Coverage is calculated as: (area of mining drills)/ (total area) * .
Rapidly increasing use of copper and nickel, especially in the developing world, has driven up demand and prices. Currently, the United States imports much of its supply—nearly 40 percent of its copper and almost all of its nickel. Here in Minnesota, we have the opportunity to change that with environmentally responsible mining.
