Exploration Best Practices Guidelines

http://www.cim.org/definitions/explorationBESTPRACTICE.pdf

Preamble: These guidelines have been prepared to assist the Qualified Person(s) in the planning and supervision of
exploration programs which will be reported under National Instrument 43-101. Such exploration programs must be
under the supervision of the Qualified Person who will be responsible and accountable for the planning, execution
and interpretation of all exploration activity as well as the implementation of quality assurance programs and
reporting. These guidelines are also recommended for use in the planning and execution of exploration programs
which will not be reported under NI 43-101. This set of broad guidelines or “best practices” has been drawn up to
ensure a consistently high quality of work that will maintain public confidence and assist securities regulators. The
guidelines are not intended to inhibit the original thinking or application of new approaches, that are fundamental to
successful mineral exploration.
Results should be summarized and reported in a Technical Report of good professional quality in accordance with
the National Instrument 43-101 and Form 1 contained in that instrument.
All exploration work from which public reporting will ensue must be designed and carried out under the supervision of
a Qualified Person (“QP”). A QP is defined in National Instrument 43-101 as an individual who is an engineer or
geoscientist with at least five (5) years’ experience in mineral exploration, mine development, mine operation or
project assessment, has experience relevant to the subject matter of the project or report and is a member in good
standing of a recognized professional association.

1. Qualified Person The Qualified Person may base the exploration program on such geological premises
and interpretation of existing information as the QP(s) may decide and select such
exploration methods and tools as the QP(s) may judge to be appropriate. In planning,
implementing and supervising any exploration work, the Qualified Person should
ensure that the practices followed are based on criteria that are generally accepted in
the industry or that can reasonably be justified on scientific or technical grounds.
2. Geological Concept The geological premise on which the exploration work is conducted including the
deposit type, geological setting and style of mineralization sought, should be supported
by relevant field data and a reasoned scientific approach.
3. Quality Assurance and Control
Throughout the process of mineral exploration, the QP(s) should ensure that a quality
assurance program is in place and that any required quality control measures are
implemented. Quality assurance programs should be systematic and apply to all types
of data acquisition, across the full range of values measured and not only high or
unusual results.
4. Exploration Methods & Data Collection
Field work is to be planned and implemented under the direct supervision of a QP(s).
Data should be properly recorded and documented at appropriate scales. All data
points should be accurately located with respect to known reference points. The QP(s)
supervising this work should ensure that any work by employees, contractors or
consultants is done by competent personnel and that appropriate quality assurance
programs and security procedures are practised. Whenever several persons carry out
similar duties or when the data has been collected over a period of time, care should be
taken to ensure the quality and consistency of the data being used.
5. Records and Data Verification
The exploration process including planning, mapping, sampling, sample preparation,
sample security and analysis or testing should be accompanied by detailed record
keeping setting out the procedures followed, the results obtained and the abbreviations
used. In addition to paper records, digital storage is encouraged in a standard format
on a reliable medium. A program of data verification should be in place to confirm the
validity of exploration data that are entered into the database. A summary of records
should be included in a periodic technical report produced and signed by the QP(s).
Practices used should be well documented and justified.
6. Sampling The practices and procedures used in each sampling program should be appropriate
for the objectives of the program. All sampling programs should be carried out in a
careful and diligent manner using scientifically established sampling practices designed
and tested to ensure that the results are representative and reliable. Samples should
be collected under the supervision of a QP(s). Quality control programs appropriate to
the type of sample and the mineralization should be planned and implemented. These
programs should include such measures as external blanks, standards and duplicate
samples. Where the volume of individual samples is reduced prior to shipping to a
laboratory for analysis, appropriate reduction procedures to obtain representative
subsamples should be applied and verified.
c
7. Drilling The drilling method will be selected by a QP(s) and should be appropriate to the
material being investigated, the objective of the program and local drilling conditions.
The drill hole size selected should provide sufficient representative sample material for
analysis and reference. Surface and downhole locational surveys should be
undertaken using techniques appropriate for the hole size, angle and length of holes. A
representative fraction of the drill sample material should be retained, however if
material is not retained, the QP(s) should report and explain the reason for this
decision.
Drill logs, forms or software specifically suited to the type of drilling, the particular
geological situation, and the minerals being sought, should be used for detailed
geological logging of core or cuttings. Logs should be appropriately detailed for the
type of drilling being conducted, the geological setting, type of mineralization, and
geotechnical conditions. Core or sample recoveries should be noted on the logs.
Cross sections depicting basic geology and hole data, including correlation with surface
geology and any nearby holes should be developed and updated as drilling proceeds.
Any downhole geophysical information or other such surveys should also be kept with
the drill log. A photographic record of the core is recommended, where appropriate.
8. Sample Security The security of samples from sample acquisition to analysis is a vital component of the
sampling process. Procedures should include the use of secure core logging,
sampling, storage and preparation facilities, as appropriate, and the prompt, secure
and direct shipping of samples to the laboratories. The QP(s) should endeavour to put
in place the best security procedures practical, given the geographic and topographic
conditions and the logistics created by the site location.
9. Sample Preparation The selection of sample preparation procedures should be approved by the QP and
should be appropriate to the material being tested, the elements being analyzed and
should be subject to the security measures as stated above. All samples that are
reduced or split should be processed in a manner such that the fraction analyzed or
tested is as representative of the whole sample as possible. Representative fractions
of the material to be analyzed or tested should be retained for an appropriate period of
time, as decided by the QP. Quality control checks should be undertaken as
determined by the QP.
10. Analysis and Testing Analysis and testing of samples should be done by a reputable and preferably
accredited laboratory qualified for the particular material to be analyzed or tested. The
selection of a laboratory, testing or mineral processing facility and the analytical
methods used will be the responsibility of the QP. The analytical methods chosen must
be documented and justified. All analytical or test results should be supported by duly
signed certificates or technical reports issued by the laboratory or testing facility and
should be accompanied by a statement of the methods used. The reliability of the
analytical and testing results should be measured using the results of the quality control
samples inserted in the process by the QP. Duplicate analyses at other laboratories
should be undertaken.
11. Interpretation A comprehensive and ongoing interpretation of all the exploration data is an essential
activity at all stages of the project and should be undertaken to assess the results of
the work.
This interpretation should be based on all of the information collected to date, be
systematic and thorough, describe and document the interpretation and discuss any
information that appears at variance with the selected interpretation. The density of the
exploration data should be critically assessed as to its ability to support the qualitative
and quantitative conclusions.
12. Mineral Resource and Reserve Estimation
Estimation of a mineral resource and a mineral reserve are both fundamental steps in
project development. The classification and categorization of these estimates must be
done in accordance with National Instrument 43-101 and be prepared by a QP(s). The
methods and parameters used in making these estimates should be in accordance with
the principles generally accepted in Canada and should be presented and justified with
the estimate.. A mineral resource can be estimated for material where the geological
characteristics and the continuity are known or reasonably assumed and where there is
the potential for production at a profit. Reserves can be estimated when a positive prefeasibility
or feasibility study as defined by NI 43-101 has established the technical,
economic and other relevant factors that indicate that these resources can be produced
at a profit. Reserve estimates should be based on input and information from a
multidisciplinary team under the direction of QP(s).

13. Environment, Safety and Community Relations
All field work should be conducted in a safe, professional manner with due regard for
the environment, the concerns of local communities and with regulatory requirements.
An environmental program, including baseline studies, appropriate to the stage of the
project should be carried out.
14. Recommendations The interpretation and assessment of the program results at the end of each phase
should determine if the program objectives have been met and if further work is
justified. Any plan for further work should identify exploration targets, recommend an
exploration program and present a budget and schedule. Any changes in working
hypotheses and objectives should be recorded.
15. Technical Reporting A comprehensive technical report signed by the QP(s) should be prepared on
completion of a particular phase or stage of work following the format presented in
Form 1 of the National Instrument 43-101.
