The Portable Originium Rig is one of the earliest facilities you unlock to place at your base in Arknights: Endfield.

This handy facility automates the process of mining Originium ore nodes. Just put it down and forget, besides checking every so often to collect the ore! Plus, it’s also required to complete the “Rally and Unite” main story quest early on.

In this quick guide, I’ll tell you how to easily place the Portable Originium Rig.

How to Place the Portable Originium Rig

There are two ways to place the Portable Originium Rig at the AIC. The first is to open up your Backpack inventory. You can do that by pressing the B key or clicking on the briefcase icon on the top right of the screen.

If you’re playing with a controller, hold L2 or LT to bring up the radial menu instead. Then, use the stick to select the Backpack on the right. It’s as simple as that!

With your inventory open, you now just need to find the Portable Originium Rig and select to place it. Then, position yourself so that you put down the rig right on top of an Originium deposit. Confirm once the hologram is white and you’ll place it down, as simple as that!

Alternatively, you can switch over to AIC building mode. For that, either click on the switch in the top left corner of the screen or press right on your controller’s D-pad.

Once in the AIC mode, you can open up the Facility List by selecting it on the bottom right corner of the screen. With a controller, just press left on the D-pad and then select Facility List.

You can find all of the AIC facilities you have in this menu. So, just choose the Portable Originium Rig and select to place it, then put it over any Originium ore deposit.

That’s all there is to it! You should now be able to place the Portable Originium Rig, allowing you to expand your AIC’s operations in Arknights: Endfield. Just kick back and wait for that sweet, sweet ore to be mined for you.
