Kathy,
I have just been assigned to review your EFRI's letter dated April 16, 2015 regarding the justification to consider
the material from the Cotter Corporation Schwartzwalder Mine as equivalent feed. I have read through the letter
and the attachments and I only have a couple of questions.
Does EFRI plan on returning the resins to be reused to Cotter or are they going to be disposed in the tailing
cells?
What is the concentration of the Uranium in this material? The Table in Appendix B did not have a result for
Uranium.
I should have a response back to you later this week.
Thanks
Ryan

Thanks for the quick response. The answers to your questions are below in blue.
Does EFRI plan on returning the resins to be reused to Cotter or are they going to be disposed in the tailing
cells?
Per the equivalent feed letter last sentence under the Disposal header on page 4 of the letter EFRI stated "In
accordance with RIS 2012-06, EFRI will return the resin to Cotter for reuse at the Schwartzwalder Mine, reuse
the resin at the Mill, or dispose of the unusable, spent resin in the Mill's tailings impoundments."

What is the concentration ofthe Uranium in this material? The Table in Appendix B did not have a result for
Uranium.
I apologize, I inadvertently omitted the uranium results from the table. The uranium result is 115,000 mg/kg
- dry.
Please let me know if you need any additional information.

Hey Kathy,

You really didn't answer my first question. So let me ask this instead. If you are planning on disposing of spent
ion exchange resins, how do you plan on disposing of them?
The reason I am asking this question is we have another facility that disposes ion exchange resins. What we
have observed is that ion exchange resins can be difficult to dispose. When ion exchange resins are disposed
in a manner that allows them to be exposed to the atmosphere, they dry out and easily become airborne. So my
concern is a health and safety concern, of potentially contaminated material becoming airborne and workers
breathing in the material.
Thanks
Ryan

Ryan,
Sorry about the confusion. Any resin disposed of at the Mill will be placed in drums and the drums will be
disposed of in the tailings.
Let me know if there are any other questions or concerns
Regards
Kathy
