As you progress through StarRupture, you’ll be tasked with sending off more materials and refined versions of said materials to the corporations. While Titanium and Wolfram will help to get you started and are very close to where you begin your adventure in StarRupture, Calcium requires you to explore the map. If you’re struggling to track it down or don’t even know where to start, don’t worry. This guide will explain all ways you can get Calcium, including where to find the lucrative Calcium ore deposits that can make fulfilling the corporation’s requests much easier.

Where to Find Calcium Ore Deposits in StarRupture

Calcium ore deposits can be located by looking for areas of pale rock in your surroundings. They’re typically found near water sources, too, making them a little easier to track down. I found one not too far to the east of my starting base and discovered it by looking out for the paler color of the rock that the calcium ore can be found in. I’ve included a screenshot of it below.

Once you’ve found one of these large veins of calcium ore, place an extractor on top of it and connect it to an Orbital Cargo Launcher with rails. You can then quickly harvest the calcium ore and complete any tasks that the corporations have that require the white-colored rock. If you need calcium for a crafting recipe, you can interact with your ore extractor and directly take any of the harvested ore from the machine and add it to your inventory.

Remember that you’ll also need to connect some power supplies to your buildings. You can place some solar generators next to one of your structures, and then use the rails to power any that they’re connected to. Power also spreads between buildings or structures that are placed directly next to each other without rails.

This isn’t the only way to get Calcium, however. You can also find small, white-colored orbs of rock dotted around the surface of Arcadia-7. These can be harvested by your tool by aiming at them and firing.

Once they break, they’ll give you a small amount of calcium, normally about three or four per orb, which will automatically be added to your inventory. It’s not a huge amount, but it all adds up over time.

While calcium ores have a white color, the silvery-gray color of Titanium ore is quite similar. As such, make sure that the ore looks exactly as the one in the screenshot above to avoid disappointment.
