Celestine, Atacamite and Troilite: routes from the Alien Ruins

1. From the Alien Ruins Research Base, travel roughly 200 m southeast and descend over the cliff.
2. Look for pale-blue crystal clusters near the Needler nest.
3. Mine with the Sonic Resonator. Without a depth upgrade, park the Tadpole above its 250 m limit and keep any swim short.

The landmark comes from an earlier walkthrough; its Sonic mining instruction is superseded by the official August 19 patch. A current-build collection demonstration remains on the verification backlog.

1. Travel about 200 m on a roughly 75° bearing from the Research Base.
2. Descend below 250 m toward the alien dwellings.
3. Look left of the dwellings, on sand near Quartz, for dark-green crystal columns. Follow the current pickup interaction: Buddy System removed harvesting Atacamite with the Sonic Resonator.

1. Head east from the Research Base, descend and follow the purple tube toward the Angel Comb beneath the Power Plant.
2. Continue northeast along another tube into the ravine and the green-pool Metal Farms area.
3. Look for green, algae-like Mineralized Clinker. The reported region is about 870 m from the base and approaches 450 m depth.

4. Mine with the Sonic Resonator and retain one raw Troilite for a farm.

A new turbine takes 10 of each finished component. Expanding the recipes from zero gives 60 Titanium, 20 Celestine, 10 Atacamite and 10 Troilite. Twenty Titanium Ingots are needed in total: ten delivered directly and ten inside Mangalloy.

Use the Power Plant planner to subtract completed Mangalloy first, then allocate existing Titanium Ingots to the direct repair and remaining Mangalloy. This prevents counting the same ingot twice. Add farm construction, reserve minerals and vehicle upgrades separately.
