Quick update for anyone following Rhino surface mining depletion/replenishment.
Credit to CMDR Tessa R Act for this one. She has been tracking and revisiting these deposits and finally caught our first confirmed positive reformation data.
She mined two 6 rig Iridium deposits to Depleted roughly 1 to 2 hours apart and revisited them about 11 days later.
Both had recovered from Depleted.
One started as High Amount / High Density and had recovered to Medium Amount / High Density.
The other started as High Amount / Low Density and had recovered to Low Amount / Low Density.
Density remained unchanged on both.
So at minimum, we can finally confirm that Depleted deposits do reform.
What we still cannot say is that the timer is 11 days. We do not know exactly when during that interval these two began recovering, and we have other tracked deposits that have remained Depleted well beyond a weekly tick. One of my own mapped deposits was still Depleted at roughly 11 days 19 hours.
That also makes the idea of a simple Thursday reset look increasingly unlikely.
The comparison between these two Iridium deposits is probably the most interesting part to me. Same commodity, same 6 rig practical capacity, and depleted within roughly 1 to 2 hours of each other, but after essentially the same recovery period the High Density deposit had reached Medium while the Low Density deposit had only reached Low.
Could be Density, total reserve, some other deposit property, or something we have not identified yet. Way too early to call it, but now we have something testable.
Tessa is continuing to follow them. A really useful next step will be seeing when they move through Low, Medium, and High, then mining one back to Depleted once it first returns to High. That may tell us whether High actually means fully replenished or whether it just means the deposit crossed back into the High Amount range.
Also, if anyone has depleted sites sitting around, I would love more data.
It does not need to be a CSV or spreadsheet. Screenshots, journal timestamps, rough notes, private messages, or just a comment here are completely fine.
The useful stuff is pretty simple:
- Commodity
- Starting Amount and Density
- Approximate rig capacity if known
- Approximate date/time it became Depleted
- Date/time of each revisit
- Whether it showed Depleted, Low, Medium, or High on each revisit
Negative checks absolutely count too. If you checked something after 8, 10, 12, 15 days and it was still Depleted, I want that just as much as a positive recovery.
If you happened to record Amount transition tonnage or total tonnage to depletion, even better, but it is not required.
Exact locations are optional. If it is a good site you do not want publicly exposed, I do not need the location to use the observation.
One request: if you are giving me updated information on a site or dataset you already shared, just mention that it is an update. I am trying to keep the data clean and avoid accidentally counting the same observation twice.
Still way too early to put a universal replenishment timer on this, but thanks to Tessa R Act we finally have something better than repeated “still Depleted” checks.
