In summary, the results of the screening tests are considered to give a reasonably strong indication of possible
ASS presence in Bores 1 and 2. However, it is considered that there was generally no strong indication of ASS

presence (with some exceptions in the upper 1.5m depth) in Bores 3 to 6. As a result of the mixed screening
test results, it was considered that Chromium Suite laboratory analysis should be conducted                                      on   selected

samples.

4.4.2      Chromium Suite Analysis


Based on the results of the screening test results, samples were selected for Chromium Suite analysis and were

kept on ice until transported to Australian Laboratory Services Pty Ud (ALS)under standard chain of custody
protocol. A summary of the test results is given in Table 3.
