Since Mars is believed to have volcanic activity in the past, there is a potential of having these precious metals. As of yet, however, robotic missions have only touched on the surface of Mars. Since water is the primary focus to support explorers, NASA is teaming up with the European Space Agency to send the Mars Express mission. With this mission will be the Beagle 2 which will act like a mole to dig down to 3 feet. As more sophisticated drilling capabilities are developed, the potential for finding such minerals will be possible.
