I made this Elethium Ore farming guide to help out players who want to farm the ores instead of buying them from the Auction House.
There are no ore ranks in Shadowlands, so the only thing that will affect how many ores you mine is your mining skill. You can farm Elethium Ore with Shadowlands Mining skill 1, but you will get more ores with higher mining skill.
Where to get Elethium Ore?
The Maw is the best place to farm Elethium Ore because the only deposit that spawns there is Elethium Deposit. You will get much more Elethium Ore than outside of the Maw.
Elethium Deposits don't spawn in other zones but you still have a small chance of getting 1-3 Elethium Ore from other Shadowlands mining nodes. (like below 5%)
Unlocking The Maw
You have to be level 60 before you can access The Maw, and you also have to complete your covenant's campaign quests. These quests will directly lead you to the Maw, so you will know when you unlock it.
Covenant campaign quests
- Kyrian Campaign - Among the Kyrian - Full Quest list
- Night Fae Campaign - For Queen and Grove! - Full Quest list
- Necrolord Campaign - Loyal to the Primus - Full Quest list
- Venthyr Campaign - Sinfall - Full Quest list
Mounting in The Maw
You can't use normal mounts within The Maw, but you can use druid travel form and the Worgen Racial.
There are only two special mounts that work within the Maw:
Corridor Creeper - Reward from 
Twisting Corridors: Layer 8.
Mawsworn Soulhunter - drops from Gorged Shadehound.
Both of these mounts will be pretty hard to get, so this is not something that you can get on your first day.
Mount Alternative
If you kill a Mawsworn Outrider, you can ride the Bridled Shadehound that they were riding. This is a temporary mount that lasts for one minute. Unfortunately, you will dismount as soon as you attack something or mine an ore.
Multiple people can benefit from a single Bridled Shadehound, so you don't have to worry about other people "stealing" your mount.
Farming Elethium Ore in The Maw
Farming routes will be different for some classes because if you have an ability like 
Stealth, 
Feign Death, or anything that lets you avoid mobs, or reset aggro, you will be able to go to more dangerous parts of the map.
These two routes below are the ones I used for farming. Both of them are good for most classes but I wouldn't recommend route 2 if you have bad gear.
There are a few patrolling elites around The Maw. If you can't get past them, it's usually just best to wait until they pass.
The Maw - Route 1
This route avoids most areas with a high density of mobs, so most classes can use this route. There is usually only 1 or 2 mobs that you will have to fight at each ore.
The Maw - Route 2
This is basically the same route, but it goes through one extra area that has a lot of mobs. It's up to you to decide if it's worth to take the small detour to get those extra ores.
Farming Elethium Ore in other zones
Elethium Deposits don't spawn in other zones but you still have a small chance of getting 1-3 Elethium Ore from other Shadowlands mining nodes. (like below 5%) These routes below will get you the most ore, so you have more chances of getting Elethium Ore.
Revendreth Route 1
This route is probably going to get nerfed.
The ores are respawning extremely quickly around this area in Revendreth. (seems pretty broken, to be honest). You will probably never even have to leave the yellow route, but if the ores are not respawning fast enough you can make a small detour to the red route.
If someone is already farming there, try to group up with him or just follow him so you can mine together.
Bastion Route 1
I think this area is also going to get nerfed. There are parts where I saw 5 mining nodes on my minimap close to each other. I don't think I have seen this many in the same area in any expansion, it just seems too good.
This area will be filled with friendly mobs and no mining nodes until you progress your Bastion Story Campaign quests!
The mining nodes respawn really quickly on this route, but there are a lot of hostile mobs guarding the mining nodes, so you will still need somewhat decent gear to kill the mobs. Check the other two routes if you can't handle the mobs. (or if this route got nerfed)
Bastion Route 2
Really good route, you can avoid fighting most mobs.
Bastion Route 3
This is a good alternative if there are a lot of players farming on the other routes.
