If you're trying to push your factory forward in Endfield, Cuprium is the first wall you'll hit. You can mine a little by hand, sure, but it's slow and it wrecks your rhythm. I usually sort out my roster and logistics first (some people even start with an Arknights endfield account Buy plan so they can jump straight into building), then I go scouting for those brown, crystal-like clusters sticking out of the ground and mark the area as a future worksite.
Finding a spot that won't fight you
Not every deposit is worth building on. You want a cluster that's tight, with enough flat space around it to place machines without weird angles. Walk the perimeter and check how close you are to water and open ground for pipes. It's tempting to grab the first node you see, but if it's wedged between rocks, you'll spend more time rotating buildings than actually mining. A good site feels boring: open, reachable, and easy to expand when you realise one rig isn't enough.
Placing Hydro Mining Rigs the right way
Cuprium needs Hydro Mining Rigs, and the placement is picky. When you're in the build menu, watch the grid highlight over the ore. The rig has to cover the node properly or it'll just sit there doing nothing. My approach is simple: place one rig, confirm it's reading the deposit, then copy that alignment across the rest of the cluster. Don't chase "perfect density" if it turns into a headache. Two rigs that run nonstop beat three rigs where one keeps failing placement.
Water lines and power that don't turn into spaghetti
These rigs drink water like crazy, so you'll need a Fluid Pump on a nearby pond or lake. Then run pipes back to your site. This is where most layouts fall apart. Use Pipe Splitters early so one pump can feed multiple rigs cleanly, and keep your pipe runs straight so you can troubleshoot fast. After that, extend power with Xiranite Pylons. Make sure every rig and the pump sit inside that blue radius, and look for the connection lines. If a machine's stalled, it's usually either a tiny gap in power coverage or a pipe that didn't snap into place.
Keeping the output steady over time
Once it's running, don't just walk away forever. Check for bottlenecks, like storage filling up or a single weak pump starving the whole line, and expand in small steps so you can tell what changed.
