<br />ANALYTICAL TESTING
<br />So]id Samples
<br />Analytical "head" samples of the six waste rock materials were analyzed for parameters
<br />contained in Table A.
<br />Liquid Samples
<br />A "head" sample of the site ground water and branch end sequential batch test leachates (cl and
<br />a3) from all tests were analyzed for parameters contained in Table B. Initial and intermediate
<br />sequential batch test leachates (al, a2, and bl) were analyzed for parameters contained in Table
<br />C.
<br />Analysis for Eh and dissolved oxygen on sequential batch test leachates was perfonmed on decant
<br />samples collected and analyzed immeadiately upon opening test jars after completion of each
<br />batch contact.

<br />Total, pyritic, and sulfate sulfur testing was performed by Standard Labs, Inc. in Casper, WY.
<br />Acid neutralizing potential testing, sequential batch testing, and analysis of liquid samples for
<br />pH, Eh, dissolved oxygen, conductivity, alkalinity, HC03, CO,, and SO, was performed by
<br />Chemac Environmental Services in Englewood, CO. Analysis of liquid san[ples for all
<br />remaining parameters was performed by Core Labs, Inc. in Aurora, CO. Copies of original
<br />analytical reports generated from this test work are included in appendix A.
<br />TEST RESULTS
<br />Results of analysis of analytical "head" samples of waste rock materials are presented in Tables
<br />IA and 1B. Results generated from analysis of the site ground water head sample and sequential
<br />batch test leachates are presented in Tables 2A through 2F.
