Ceramic Proppant

I am working on a frac sand project and wondered if anyone could share some insight/expertise to help me out? A friend of mine has some black ceramic proppant that was abandoned at a Seattle shipping yard and is going to be sold to pay off the liability. Most of the ceramic sand is ISP 16/30. There are also some ISP 20/40 and a couple totes of ISP 30/50 available. Any idea what this type of sand sells for and any buyers that purchase/use this type of sand?

We are offering a 3% finder’s fee for anyone that can find us a buyer. Thanks for any assistance you all can provide!

Can you estimate how much is there?

Steve - We have 2 totes of ISP 30/50, 15 totes of ISP 20/40, and 1,292 totes of ISP 16/30. We can send samples out to any interested buyers. Totes weigh 3,300 lbs - 56 totes per rail car.
