Mining on Mars has had an interesting history over the years of the Ad Astra landings. It was originally done with massive rovers equipped with several crushers and scoops that scraped the surface of ore. In the years after, the presence of ore on the surface near the Ad Astra Zone had diminished and a new way to mine was developed in the form of the Mining Rig. The building is a hybrid of traditional mining methods without the need for settlers to be subjected to the underground for long hours and bleeding-edge science in order to maximize the efficiency of these mining rigs. The ones within the Ad Astra Development Zone are much bigger than the ones in Duskworks, most are cleverly disguised as buildings or towers akin to the Los Angeles oil pumps.
