Using a gold wash plant, exposed gold-bearing gravels are mined using a bulldozer that pushes and stockpiles the gravel near a wash plant.The stockpiled gold-bearing gravel is then fed into the wash plant by a front-end loader or large backhoe. This practice promotes equipment efficiency by allowing the bulldozer to continue mining while the loader or backhoe feeds the wash plant at a steady rate.

In the mining valuation model Excel templates or mining financial model XLS, included are the projections of the expected metal content of ore mined, relevant income, and cost drivers, and come up with financial projections for a mining operation.
Mining is usually a permitted use in the Industrial District. If zoned in the Agricultural District, a Special or Conditional Use Permit for Mining, with or without blasting, may be required. Quarrying solid rock, like limestone and granite, requires blasting, whereas mining sand and gravel generally does not.
Mining ventures purchases land and the rights to explore for 100,00. Exploration costs are 20,000, and development costs are 30,000. The estimated cost of restoration, calculated as the present value of expected cash outflows, is 50,000.
