QCOAL REACTIVITY TEST REPORT

Testing of Samples using AEISG code testing for reactivity over a period of 7 days.

REQUESTED BY: GODFREY BANDA

REPORT NO.: QMR03-12-24

Table 1 - Results for Testing using the AEISG Code of Practice

Table 2 - Results for Testing using the QMR Reactive Ground Test

Prior to  testing as per the AEISG Code of Practice each sample was assessed for reactivity risk based on pH, carbonate and amount of reactive sulphide  using the QMR Reactive Ground Test (refer to Table 1  and Table 2  for results of both tests).  One  sample, CP-16 contained more than a trace level of reactive sulphide at 6%.    The pH of this sample was 8 and the sample has a high carbonates content.  The high levels of pH and carbonats inhibited a reaction when tested as per the AEISG Code of Practive.

Conclusion:

All samples were found to be not reactive when tested as per the AEISG Code of Practice and QMR Reactive Ground Test.
