Prior to testing as per the AEISG Code of Practice each sample was assessed for reactivity risk based on pH, carbonate and the amount of reactive sulphide and coal using the QMR Reactive Ground Test (refer to Table 1 and Table 2 for results of both tests). All 3 samples contained visible pyrite (refer to Figure 1, Figure 2 and Figure 2). All samples were inhibited by the coal which inhibited a reaction between the sulphide and nitrate when tested as per the AEISG Code of Practice. It should be noted that in acidic conditions Sample 92-ER02 would spontaneously react due to the high amount of reactive sulphide.
Conclusion:
All samples were found not to be reactive when tested as per the AEISG Code of Practice and the QMR Reactive Ground Test. The QMR Reactive Ground Test indicated that the sampls 92-ER02 will react if subjected to acidic conditions.
