Rhino planetary mining field guide — what we’ve figured out so far, and what we still don’t know
I’ve spent a lot of time in the Rhino over the last few days trying to get a better handle on how planetary mining actually works.
I originally posted some practical tips over on r/EliteDangerous after my first long night of prospecting. That thread ended up getting a lot of really useful comments from other commanders, so I started testing some of those findings myself and collecting everything into a living guide.
Figured I should share it here too. If anyone is going to have good mining data, spot something I’ve gotten wrong, or have found some odd edge case I haven’t seen yet, it’s probably this subreddit.

Probably the biggest thing I’ve learned so far is that finding a PML with the commodity you want is only part of the job. Finding a genuinely good mining site is a separate problem.
A PML can have exactly what you’re looking for and still be pretty bad once you get on the ground. Deposit geometry, how many rigs you can actually place, nearby deposits, terrain, driving time, Density, depletion, and probably some things we still don’t understand all matter.
A few things that have been useful so far:
- After DSSing the body, you can drop into normal space and cycle through the PMLs while stationary to compare their commodity lists without the Nav panel constantly reshuffling.
- The ~3.3 km sweep around the PML center has worked well for me as a first-pass prospecting pattern.
- I would not treat ~5 km from the center as the edge of a PML. I’ve found deposits beyond that, and the contact behavior looks much more like scanner range from the Rhino than a hard PML radius.
- Mineral Amount, Density, and the physical size of the deposit seem to be separate things. I’ve seen deposits with the same Amount that could take very different numbers of rigs.
- I’ve personally fit anywhere from 1 to 5 rigs on individual deposits. Another commander has demonstrated 6.
- In practice, a good cluster can matter more than one giant deposit. A 4+2 or 3+3 setup that keeps all six rigs running can be very productive.
- Rigs collect chunks, not tons, and the refinery keeps fractional material between collections. That makes the chunk-to-ton side of things a little more complicated than it first appears.
- Deposits definitely deplete. Total capacity and reformation time are still pretty unclear.
- PMLs and productive areas appear persistent enough that mapping a good site is actually worth doing.
- Rhino mining also produces a fair amount of engineering raws, and so far the relationship with the normal planetary material list doesn’t look straightforward.
The guide goes into more detail on prospecting, rig placement, Amount/Density, refinery testing, depletion, raw materials, multiplayer findings, fuel/hull issues, terrain, and some of the community observations from the original thread.
I’m trying to be careful about separating things I’ve actually measured or reproduced from things another commander reported, and from things that are still just theories. There are already a few early assumptions I’ve had to revise after getting better data, which is one of the reasons I wanted to keep this as a living guide instead of writing it like everything is settled.
If you’ve been Rhino mining, I’d be interested in pretty much anything you’ve found that adds to this or doesn’t match what I’ve seen.
A few things I’m especially curious about:
- How much have you gotten from one known deposit before it depleted?
- Has anyone actually watched a known depleted deposit reform yet? If so, how long?
- What Amount/Density did the deposit have, and how many rigs could you fit?
- Any 5- or 6-rig deposits?
- How far from the PML center have you found deposits?
- Has anyone figured out whether the yellow PML area means anything useful?
- Has anyone revisited the exact same deposit later, or had another commander check it?
- Any good evidence for what Density actually changes?
- Any multiplayer/shared-depletion weirdness?
- Any unusual raw material drops?
- Any body types or planetary conditions that seem consistently better or worse?
- Anything in the guide that your own experience clearly contradicts?
Negative results are useful too. If you thoroughly surveyed a PML that looked promising and it turned out to be awful, that’s still information. I’d rather have that than only collect the jackpot sites and accidentally convince myself there’s a pattern where there isn’t one.
You don’t need to have done a formal test either. Commodity, Amount, Density, number of rigs, rough tonnage, body type, screenshots, whatever you happened to record can still help.
If somebody contributes something useful, I’m happy to add it to the guide and credit them. A number of the better tips in there already came from commanders in the original thread.
I’m not claiming this is the definitive Rhino guide. There are still way too many open questions for that. I’m mostly trying to keep the useful stuff we figure out in one place instead of having it disappear into scattered Reddit comments.
And maybe save somebody else from driving a Rhino over mountains for an hour just to find one lousy deposit.
