I dunno if this will help but this is what I use:
If I happen to dug/depleted sup mats on a certain season I need to wait for another 2 available seasons + the current season to dug again the sup mats. It seems for me that mats are always refilled on the 3rd available season.
If I happen to received depleted message and I don't know when it was depleted then I just add 1 available season or I could wait for another reboot/reset to gain the timer.
I could be wrong on my observation.
