Reporting

You asked

7.8.2.1  i) The date of the test or calibration.

For geology/mineral reports, is this necessary? I know there have been some changes in reporting requirements, but if the date of testing does not affect the validity of the results, is 7.8.2.1 i) necessary?

Note that ISO 17025 states that all must be included unless you have a valid reason for not. This tells you if you have considered the risk and are confident the results are reported suitably (not ambiguously) then you can justify a simplified report. As long as the information is retained, i.e as long you can find the raw data if you have a query and need to troubleshoot.

You also asked about clause 7.4.3.

The standard requires you to a have a process to a) assess against a requirement, that a sample is suitable for testing. For example the criteria may be water in a 1 litre glass bottle, filled to the cap, temperature below 5 degrees Celsius); b) to consult the customer and agree on the way forward if there are deviations and c) record deviations and agreements and keep the records.
