V Exploration Results General Requirements When disclosing the results of exploration activity on its properties, a company shall state the source of the information when it was not obtained by the company itself. The company shall also provide the name(s) of the qualified person(s) responsible for the design and conduct of the exploration program. The relationship of such person(s) to the company shall also be disclosed. Apart from disclosure of results of exploration activities as described in more detail below, a general description of the geological environment must be disclosed, including any known potential for problems, such as extremely erratic results or significant metallurgical difficulties. If the company releases partial results, e.g., the first two holes of a six hole program, it must ensure that the balance of the results are disclosed in a timely manner whether the results are positive or negative. Where possible, the company should provide information in table form for ease of understanding and publish maps, plans or sections as appropriate to the information and the stage of development of the property.
VII Advanced Results When the company is releasing information as to advanced results, it must provide a description of the work undertaken and include all relevant details as to the methods used and who conducted the program in a similar manner as for preliminary results.
Results must not be disclosed selectively. If, for example,
six holes are drilled and three return mineralization of interest, details of all six holes must be released, including location, direction, geological formations encountered, etc., so as to provide the reader with as complete a picture as possible as to the nature of the prospect. Grades reported should conform to industry best practices, such as ounces per ton or grams per tonne for precious metals, and a complete and accurate portrayal of the drill intersections, true widths, cut grades, etc., should be included. For any material properties, the company must also disclose whether any independent sampling or audit programs have been or will be undertaken, by whom, and what their qualifications are. Data verification programs should be disclosed, including sampling methods, location and number of samples, and comparisons with the company’s own results. Care should be taken to provide consistent reporting throughout the life of the exploration program. Estimations of tonnage and average grade of mineralization may not be reported until the company has performed a resource calculation as set out in the
Resources and
Reserves Definitions
section below.
VIII Assay Results
The name of the analytical laboratories which assayed the
material sampled must be disclosed together with their
relationship to the company, if any. The accreditation of
each laboratory, or lack thereof, must also be disclosed.
Assay results must include disclosure of the analytical
method(s) used. If these are not standard procedures for
the prospective minerals on the property, this should be
disclosed in detail, including a discussion of the reasons
for their use.
Complete disclosure of check assay results is not required.
It is, however, a requirement that the company disclose
the nature of the check assay program and whether the
results are confirmatory.
