The ground survey will show a lot more detail and will be a much more colourful puzzle for you to unravel with four different types of results. The current example screen has yet to be properly represented here but should be similar in appearance to aerial surveys. You should be able to conclude with a fair degree of certainty that you have found something valuable and if you are convinced of this then the next step is to continue with a Test Drill. This procedure is much more expensive and will take longer to prepare before you can view the results. You might be unlucky and you find nothing or hopefully it will confirm your suspicion to potentially build a mine there. This step is a much more expensive process and will also take longer to get the results. Any positive results will be summarised in mining plots and that's where to go next.
