A survey charge is a small explosive that is used to determine the mineral content of an area of ground. The survey charge is placed on the ground where it explodes and throws an amount of resources into the air. The resources thrown are directly proportional to the yield of a mining quarry when placed over the crater left by the survey charge. The impact crater can also be examined manually which will generate a note containing the numerical analysis of the minerals present.
The survey charge also deals damage in an area of affect upon explosion. While ineffective against players due to the fuse and low damage, it can be used to help raid sheet metal doors if they are available, and provide enough damage to not be worth recycling instead.
