I do not know if there are any, but from lack of replies here I think it is unlikely. Maybe a developer, if any are still with the project, can jump on and provide information.

I could only find very minimal miner interest at: https://miningpoolstats.stream/pigeoncoin

It looks like there are 6 to 10 people mining it at any given time, mostly solo mining. I mined a couple hours the other day when I first posted, just for old time sake, and was able to mine a couple hundred K in a short amount of time.

I am not sure if PGN still has a future, but this would a good opportunity for anyone who like to mine these old coins in case of a future run.

Anyway, my only interest in the coin at this point is just that I happen to have an old wallet that has a small balance left.
