Minerals Exploration Checklist

Activities

• Are activities reasonable and appropriate given exploration objectives and circumstances?
• Are expenditure on activities reasonable for the activities described?

Data & Results

• Are data and results complete for the activities undertaken?
• Are data and results accurate, reliable and authentic?

Data & Results Checklist

Below are examples of what geoscientists look for when reviewing Mineral Assessment Reports on behalf of the Crown to ensure quality of data and results justify the work expenditure.

Physical Work

• Are lines/grid, local trail/road, topography, trenches, open cuts, underground cuts, reclamation, helipad, etc. shown on maps with metric dimensions noted?

Geological

• Do geology maps show outline of outcrops and identify lithology, structure, mineralization/specific minerals?
• Are the written results and maps comprehensive?
• Are petrographic and mineralogical analyses reported?
• Are photo-geological interpretations accompanied by ground surveys?

Geophysical

• Is the magnetic survey component measured and identified?
• Are absolute/relative values and diurnal correction described for magnetic surveys?
• Is the specific method for electromagnetic survey described and the VLF transmitter location noted?
• Are the specific method and elctrode array described for any induced polarization surveys?
• Are airborne survey results in contour form, 1:50 000 scale or more detailed?
• Are physiography, permit boundaries, flight lines, ground clearance, speed, and weather/wind vector noted for airborne surveys?
• Are other types of surveys fully described?

Geochemical

• Is material sampled identified and described as to appearance, soil horizon/depth; silt from active channel/bank; rock-type; vegetation species/part of plant; assays and metallurgical investigations described.
• For laboratory analysis, are the analytical laboratory and chemist named?
• For laboratory analysis, are the mesh fraction analysed, strength of reagents and time of digestion, and testing instruments identified?
• For bio-surveys is the ashing technique identified?
• Are analytical result certificates included in report?
• Is any airborne survey presentation similar to airborne geophysical survey.

Drilling

• Are the drill-hole collar location, elevation, inclination/azimuth, dip test results, and hole/core diameter reported?
• Are core/cuttings logs described by a geologist?
• For core/cutting log description are the geologist's qualifications are included in report?
• Are assay results correlated with logs, with a note of any assays not done?
• Are shot holes for blasting reported separately from drilling reports?

Prospecting

• Is an accurate map provided, showing location of each traverse, location and description of rock outcrops/float, and sample locations?
• Are samples appropriately described (sample I.D., sampling method; sample size; physical description; location)?
• Are analytical results included and referenced by sample I.D.?
• Are any instrument readings described and plotted?
• For further information please refer to the Guideline for Prospectors
