Physics-based space mining simulator Delta V: Rings of Saturn, stylized as ΔV: Rings of Saturn, came out of early access this week. It is, in my opinion, the best space mining game you can play. It's a hard sci-fi game about physics, paydays, fission-powered space ships. It's also a gobsmackingly cheap $10.
I think developer Kodera Software describes it best: "Every action has a reaction, lasers are invisible without a medium, and your thrust is a potent weapon." It's the kind of game where your thrust exhaust heats up and pushes nearby things away, where your radiators start glowing when you pump heat, and where there are no energy shields to save you from your bad choices.
