Requirements Of Geophysical Submissions For Assessment Credit (Section 14)

Any geophysical survey report submitted for assessment work credit must, in addition to complying with the requirements of subsection 11 [Geotechnical],

• identify the name, type and model of the instrument used to perform the survey, specifying the scale constant or sensitivity;
• describe the method of survey and the use of the instrument and operational technique;
• specify the total distance of line traversed for each type of survey performed;
• give the background count for radiometric readings;
• identify the sources of any geophysical or geological data contained in the report or shown on the accompanying illustrations which have been obtained from any source other than the survey being reported;
• in cases of underwater geophysical data, specify the method of navigation or ground control related to data recovery;
• give an analysis of the geophysical data to better define the geometrical and physical parameters of the anomalous zones;
• describe the possible causes of background and anomalous values relating the latter to known or speculated causes; and
• give a brief evaluation of the significance of anomalous values and recommendations for further exploration work.

Any geophysical map or plan submitted in connection with a geophysical survey report must, in addition to complying with the requirements of subsection 11 [Geotechnical survey],

• show all station points, the values of readings taken and the units measured such as gammas, degrees, milliamps, milligals, milliseconds and ohmmeters, and dimensionless units such as percent and ratios;
• show basic numerical data and filtered data if available;
• indicate total radiation units or radiation units from uranium, thorium or potassium separately or in combination for radiometric surveys on land;
• show where appropriate, the location of a topographic feature as a main base control point;
• show profiles or contours as determined from the values obtained by the survey and give the vertical scale where profiles are used;
• contain a legend or explanation indicating how the measured units in clause (a) are plotted, anomalous zones are indicated and spurious suspect readings are identified and indicating the radiometric background count;
• contain an outcrop map where a radiometric survey has been performed;
• show recovered tracks and sub-bottom information, if available, for underwater geophysics; and
• provide a plan showing the projection of the drill hole to surface with the loop configuration, and a drill hole section for a down hole survey.
