Guideline for Prospectors
Samples and Maps in Mineral Assessment Reports
Maps
Maps are typically included in reports on prospecting to illustrate the following:
- Traverse line locations. Not just the area explored, but the exploration route.
- Sampling locations, with reference to the Sample I.D.
- Location of outcrops and other significant landforms described in report.
Criteria for maps pertaining to prospecting activity and findings: - Remember to include two original copies of each map.
- Map scale should be 1:50,000 or better.
- The quality of the map must be suitable for reproducing.
- Mechanically produced maps are preferred.
- Hand-written notations and markings must be of suitable quality to reproduce.
Samples
1. Sample I.D.
Each sample must be identified with a unique code or number, to be used on all sample descriptions, analytical certificates and sample analysis reporting.
2. Sample Description
Describing the sample completely and accurate adds value to results and ensures they are reproducible, i.e., the same results would be obtained by someone else under exactly the same conditions (same place, same time, same method, etc.)
Where you obtained the sample:
- When you obtained the sample: date and/or trip number referenced in your report.
- How you obtained the sample: e.g., panning, rock grab.
- How much you obtained in each sample, by weight or volume.
- What you obtained:
- Description of mineral, chemical and physical characteristics of sample, to the best of your ability; and/or
- Certified analysis or assay results obtained during the work assessment period. All lab results should be referenced to the Sample I.D.
