Memo - The BMRI File
Selection of Third Party Contractor & Lab
page 2

I eliminated Shomaker, Inc. from consideration and invited the remaining two
sampling nominees to oral interviews.
Dr. Harry Posey of our DMG staff, Andre' J. Douchane of BMRI and I ~onducted
the approximately 1 and 1/2 hour interviews. Both of the nominees,'
RCG/Hagler, Bailly, Inc. and Waste, Water & Land, Inc., submitted written
proposals following their interviews. My final decision was based upon a
consideration of all written submittals, the oral interview, and diskussion
with Dr. Posey.
Selection of the Analytical Laboratory
The fee schedules of Analytical Technologies, Inc. and Core Laboratories, Inc.
are similar, so cost did not appear to be a discriminate factor. Bo h
laboratories are EPA certified, and have extensive analytical experience in
mining related situations. Each laboratory is capable of performing the
procedures specified within the TR-006 analytical protocols, however
Analytical Technologies has never performed weak acid dissociable (W,A.D.)
cyanide analyses. ATI's routine cyanide analytical services include "Free",
"Total" and "Cyanide Amenable to Chlorination". They do possess the equipment
necessary for W.A.D. cyanide analysis and are receptive to providing the
services.
At my request, Dr. Posey, an experienced geochemist, conducted in de th
telephone interviews with both laboratories. Harry has also been chiefly
responsible for the geochemical opinions rendered by DMG throughout the past
six months analysis of the BMRI violation abatement. It is Dr. Po seyi's
recommendation that the Division designate Core Laboratories, Inc. asi the
analytical laboratory to perform the analytical determinations for th~ "third
party monitoring" at BMRI's San Luis mine. Harry cites the start up ime
required for ATI to perfect W.A.D. techniques, the extensive experience of
Core Laboratories in W.A.D. analysis, and Core's demonstrated willing ess and
ability to perfect their techniques to achieve the required QA/QC per ormance
in analyzing BMRI samples, as justification for his recommendation. I concur
with Dr. Posey's recommendation and designate Core Laboratories as th$
analytical laboratory for the third party monitoring sample analysis.
S2lectio~ of the "Third Party Sampler"
Ann S. Maest, PhD., participated in the interview and prepared the written
proposal for RCG/Hagler, Bailly, Inc. Dr. Maest is an experienced ge chemist,
with experience in environmental impact related geochemical project a pects.
Dr. Maest is also qualified and experienced in water quality, water r source
evaluation, and sedimentology. She has significant first hand experielnce in
water quality sampling and geochemical analytical procedures. Dr. Maelst
proposes to conduct the water quality sampling and report preparation
personally. Dr. Maest proposes to complete a pre-sampling examination of
