The result of the exploration phase is measured in terms of mineral resources and ore reserves. Mineral resources: The concentration of materials in or on the Earth's crust that have reasonable prospects for economic extraction. Ore reserves: Those parts of a mineral resource that can be economically mined.

Although its price fluctuates, gold regularly sells for more than $1,000 per ounce. Gold nuggets are popular among collectors but are rare; most gold is found as small particles buried in gold ore. Mining just an ounce of gold from ore can result in 20 tons of solid waste and significant mercury and cyanide contamination, according to Earthworks.

1. Exploration EXPLORING FOR GOLD IS A COMPLEX, SCIENTIFIC AND TIME-CONSUMING PROCESS. With odds of only one in 3,000 discoveries leading to mine development, and only 10 percent of the world’s gold deposits containing enough gold to mine, exploration can be labor-intensive, time consuming and expensive.
