Adequacy Issue No. D. Attachment D -8, Whole Rock Sampling and Kinetic Testing
Work Plan
1) For all solids tests (e.g., SPLP, humidity cell, acid -base accounting,
whole rock analyses, solution characterization methods), the Applicant
must commit to consulting with the Division prior to the tests to
determine appropriate sampling and analytical parameters, including, but
not limited to, what is regarded as a representative sample, the
appropriate analytical suite for each test, and laboratories that are
qualified to perform the tests.
2) ABA: In addition to total sulfur all tests must include sulfide sulfur.
3) Humidity Cell Test: Collection of sample material for the tailings
humidity cell test must be done with the DRMS geochemist present. The
humidity cell test must be conducted under the conditions outlined in the
Division's adequacy review of 25 March 2011, i.e., the test must be run
indefinitely or until notified otherwise by the division and the analyte list
must be as described in the 25 March 2011 review.

Wildcat commits to consulting with DRMS for all solids tests (e.g., SPLP,
humidity cell, acid -base accounting, whole rock analyses, solution characterization
methods) prior to the tests to determine appropriate sampling and analytical parameters,

Response to Adequacy Issue No. D.2.
Wildcat will include sulfide sulfur in the ABA protocol which also quantifies AP,
NP, Net NP, paste pH and acid soluble sulfate and sulfide.
Response to Adequacy Issue No. D.3.
Wildcat will collect sample material for the tailings humidity cell test with the
DRMS geochemist present. Wildcat will conduct the humidity cell test under the
conditions outlined in DRMS' March 25, 2011 adequacy review, i.e., the test will be run
indefinitely or until notified otherwise by DRMS, and the analyte list will be as
described in the March 25, 2011 review.
