Division of Minerals and Geology -Spero Ore Smdy FINAL REPORT
ANALYTICAL TESTING and TEST RESULTS
Mine Water Samples
All four mine water samples were analy~xd for the following parameters:
Major [on chemistry: pH, Conductivity, TDS, Alkalinity, Bicarbonate, Carbonate, SO„ CI,
Ca, Mg, Na, K
Total Cyanide, WAD-Cyanide, Free Cyanide
Trace Metals: Al, As, Cu, Cd, Fe, Pb, Mn, Ag, Zn
Mine water sample test results are presented in Table 4.
Single Contact Batch Leachability Tests and Sequential Batch Leachability Test Leachates
Leachate samples generated from single contact and seyuential batch testing were analyzxd for
the following parameters:
Major Ion chemistry: pH, Conductivity, TDS, Alkalinity, Bicarbonate, Carbonate, SO„ CI,
Ca,Mg, Na, K
Tutal Cyanide, WAD-Cyanide
Trace Metals: Al, As, Cu, Cd, Fe, Ph, Mn, Ag, Zn
Single contact batch test results and results from the leachate generated from the first contact of
each of the two seyuential hatch tests are contained in Table 5. It should he noted that test
conditions utilized in performing the first contact of each sequential batch test were essentially
the same as [hose used during single contact batch tests. Sequential batch test leachate test
results are contained in Tahles fi and 7.
All batch testing and sample preparation and handling prior to submittal for analytical testing
was performed by Chemac Environmental Services in Englewood, CO. All analytical test work
on mine water samples and batch test leachates was performed by Auburn Analytical Inc. in
Auburn, Alabama. Copies of original analytical reports generated from this test work are
included in appendix A and appendix B.
