Keene Engineering Inc.

Pat Keene is one of those people who treats everyone with respect no matter their social standing. I learned more from 10 minutes of talking to him than I learned in hours of study.

Keene Engineering manufactures quality mining products. I have bought many items over the years and have always been satisfied. Pat and Mark are great guys who know how to run a professional business.

I picked up a 42+yr old a52 at an estate sale and I bought the classifier screen upgrade earlier this year and am super happy with amount of fine gold it recovers. However...I have already worn the zinc coating off of screen and riffle board. I've also noticed that the "ramp" going up keeps wanting to flatten out and some of the smaller rivets are coming loose. I do use it at least twice a month, but am curious how many yards of material can be run before having to replace parts. If you need a serious miner that's actually running placer gravels to test products please feel free to contact me.
