Basically, it's 'Mørk', which in Danish means 'Darkness', and then we added 'ite', as in stalactite, so it becomes 'Morkite'... the Dark Mineral

Morkite is a basic Mineral that appears in the Mining Expedition mission in Deep Rock Galactic and "Extract Morkite" objective for Deep Dives. The primary objective in Mining Expedition consists of gathering a certain amount of Morkite, ranging from 200 to 400 units of it. Morkite will appear in your inventory, much like many other resources, and must be deposited into the M.U.L.E to count towards the primary quota.
Morkite Ale was hinted on the Public Service Announcement (PSA) Boards before Update 17: "Oktoberfest" hit. Once the update came out it makes an appearance under the name "Dark Morkite" in the Abyss Bar.
