Reference: Cresson Project; Permit Number M-80-244: Request to Revise Source Rock For
Drain Cover Fill Material Placed Over Pregnant Pond System.
Deaz Mr. Keffelew:
In accordance with our discussion of today, the Cripple Creek & Victor Gold Mining Company
is confirming its request for approval of a change in the source of Drain Cover Fill material and
Select Drain Cover Fill for the area of the pregnant pond (pregnant liner system or "PIS") of
the Valley Leach Facility. In the case of the Drain Cover Fill for the PLS, we ask to change
the source from crushed Cresson ore to either all Pad #2 material or a grid of crushed Cresson
ore and Pad #2 material. The choice would be CC&V's with notification of that choice to the
Office of Mined Land Reclamation. The "grid" would be created by placing Pad #2 first to
protect pipes and to buttress other fill and by then placing ore between the Pad #2 grid. In the
case of the Select Drain Cover Fill, the request is also to add Pad #2 material as a source in
addition to crushed Cresson ore. This is not a request to change any technical requirements but
only the source of material and the source is one that is already serving as a source for a similaz
application. Presently Pad #2 material is the source for cover on the other portions of the pad.
As we discussed, and you and Mr. Sorenson recalled, our initial proposal in 1993 was to use
only Pad #2 material as Drain Cover Fill. We then requested, and the Office accepted as part
of the approved plan, use of Cresson ore on the PLS. Our request was for purposes of placing
leachable ore on the system at an early date. In view of the lateness of our ability to crush ore
(due to the lateness of initiating construction), it appears that we would not be able to generate
enough ore to place on the pad in a timely manner. The Pad #2 material is immediately
available and, through its use, we could immediately begin to cover the upper liner and stabilize
the piping system that lays on top of that liner. It is possible that some crushed ore could
