Finding Calcium can feel like searching for treasure in StarRupture. Unlike Titanium and Wolfram, which practically announce themselves with massive deposits, Calcium plays hard to get. You'll need this resource by the truckload for advanced building projects, corporation upgrades, and crafting Calcite Sheets. The good news? Once you know where to look and how to set up proper automation, you'll never run short again.
Where to Find Calcium
Calcium shows up in three main forms. They look similar on the surface, but they are not equally useful.
Meteorite Clusters
Meteorite clusters are usually your very first source of Calcium. You will see scattered, still-smoking meteorites across the terrain. When you mine the materials covering the meteorite, the whole thing breaks apart and drops everything inside. A large meteorite usually gives around ten to fifteen Calcium, mixed in with other resources.
Small Calcium Ore Nodes
Around meteorite sites, you will start to notice small Ore nodes. These look a bit like Titanium nodes. The difference is in the surface texture. Titanium looks shinier and metallic, while Calcium has a dull, chalky look, almost like someone dropped chalk dust on a rock.
You mine these nodes with your laser tool. They provide more Calcium per node than a meteorite does, and they are a decent step up from scraping meteorites all day. However, they still rely on manual harvesting. You are pointing a laser at rocks over and over, and that does not scale when the game starts asking for hundreds of units at a time.
Large Calcium Ore Deposits
The real solution to Calcium problems is the large Ore deposit. These deposits are easy to miss if you do not know the visual clue to watch for. They look like broad, flat sandstone ledges or plateaus with shallow pools of water scattered over the top surface. Those water pools are the big giveaway that you have found a Calcium deposit worth building around.
These are the only Calcium sources that work with Ore Excavators. That is the key detail. If you want a steady, automated supply of Calcium, you need to be mining one of these water-topped plateaus, not just wandering around picking at nodes.

Map Locations for Major Deposits
Two primary Calcium deposits sit within reasonable distance of your starting location, making them ideal for your first expansion base. If you've unlocked the map upgrade from our StarRupture Ultimate Beginners Guide, these deposits appear as gray-brown patches.
The northeastern deposit offers the smoothest terrain for building your secondary base. You won't fight elevation changes as much when placing structures and connecting rail systems. The western location provides natural rock formations that can help protect your base from threats, though it requires more careful planning for your logistics network.
