How do you optimize the sampling and analysis of drill core and rock chips?

3 Collect and record your samples

When you collect your samples, you should follow the sampling protocol that you defined in your strategy and document every step of the process. You should record the location, depth, orientation, length, width, weight, and description of each sample, as well as any relevant observations, such as lithology, alteration, mineralization, structure, and weathering. You should also assign a unique identification number to each sample and label it clearly and securely. You should store and transport your samples in a safe and orderly manner to prevent damage, loss, or tampering.

4 Analyze your samples

To analyze your samples, you need to choose a suitable laboratory that can perform the tests and assays that you require. You should also select the appropriate sample preparation and analytical methods, depending on the type and quality of your samples and the elements and minerals that you want to measure. You should communicate clearly with the laboratory and provide them with the sample information, the analytical specifications, and the QC/QA requirements. You should also monitor the laboratory performance and check the accuracy and precision of the results.

5 Interpret your results

Once you receive your results from the laboratory, you need to interpret them in a meaningful and objective way. You should use appropriate software and techniques to visualize, manipulate, and analyze your data, such as graphs, maps, histograms, scatter plots, statistics, and geostatistics. You should also compare your results with other sources of information, such as geological maps, geophysical surveys, and previous studies. You should identify and explain any trends, patterns, anomalies, or discrepancies in your data and evaluate their significance and implications for your exploration project.

6 Review and improve your process

Finally, you should review and improve your sampling and analysis process on a regular basis. You should assess the strengths and weaknesses of your process, the challenges and opportunities that you faced, and the lessons and recommendations that you learned. You should also solicit and incorporate feedback from your team, your peers, and your stakeholders. You should use this information to refine your sampling strategy, optimize your sampling equipment, enhance your sampling quality, select better analytical methods, and improve your data interpretation skills.
