The Cold Storage quest in Arc Raiders is the second you'll have to complete on the new map of Stella Montis after In My Image, and this one sees you tracking down a J Kozma Ventures Container. This is located somewhere on the map, but Shani has no clues for you besides mentioning that the container will be marked with that name.
In a nice bit of luck, I found one of these containers (there might be multiple) right by an extraction point. Below I'll explain exactly where, and even though you have to exfil an item for the second stage of this quest, it might be worth just bringing a free loadout with the extraction point right by where you find the container.
