The miner as shown on the official site
The miner is a structure that mines materials for the player, specifically ore such as Iron Ore.
A smaller drill is shown at 00:30 in the official trailer for the game after a demonstration of the scanner, so it's quite possible that the Miner is not the only option for collecting ores, however, keeping the quote from Steve in mind, it is likely that these are the only two mining structures in the game. However, in a developer blog posted on November 8, 2018, community manager Jace showcased a sneak peak at gameplay of the game's alpha, where a mining drill, visible at around 1:35, displayed the name 'Miner MK1', indicating at the presence of other, higher-tier miners.
