Reactivity Test Report
Hunter Valley Operations NOVEMBER 2024 | QMR1501124
Testing of Samples as per Table below using AEISG code testing for reactivity over a period of 7 days.
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). Of the 43 only 4 samples contained more than 1% reactive sulphide as described in Table 3. All samples testes at not reactive.
Table 3 – Samples containing more than traced reactive sulphide
Figure 1 –Sample 5445C-RG10 was the only sample to give a temperature isotherm when tested as per the AEISG Code.
Conclusion:
All samples are not reactive when tested as per the QMR Reactive Ground Test and the AEISG Code of Practice.
