Add more challenge to your game by postponing imersite mining on Nauvis until you mastered asteroid mining. This mod will lock the imersite drill behind the advanced tech card, and you'll need to bootstrap it by acquiring imersite in space - mostly en route to Aquilo or traversing the asteroid belt (should you choose to install that mod), though Fulgora also has some trace amounts of it too.
