Test drilling for gold is an important step in prospecting and eventually commercially mining for gold. Test drilling is done to get a continuous sample of the bedrock of a given gold project. The sample is then tested to determine if there is gold in the project area and to estimate the amount of gold that can be mined in the area. Quite often test drilling may produce a variety of result as each hole may encounter different types of rocks and soils, however, it is the most effective method used to estimate the amount of gold ore in a given deposit.
