All of the data from logging the core was recorded in hand written logs and then
transferred to Microsoft Excel spreadsheets, for later import into a geological
software package.
10.4.3 PROPHECY PLATINUM METHOD AND APPROACH
The following description of the sampling methodology was provided by Rory
Calhoun, P.Geo.:
• Drill core is delivered to the core shack (Figure 10.2) by the diamond drill
contractor.
• Core boxes are sorted and placed in groups of three.
• Group of boxes are photographed.
• Run markers and other marker blocks are checked for accuracy.
• The geologist collects RQD and recovery data on a paper form, to be
transferred later to a spreadsheet.
• Core is logged by the geologist on a paper form.
There are no lithological codes, as the logs are written long hand.
There is only one geologist logging the core for consistency.
• The minimum sample unit is 2”; maximum sample length is 5 ft (1.52 m).
• Samples do not cross lithological contacts.
• The sample is marked on the box with the footage and sample number.
• Samples are taken to the core cutting facility for cutting by a technician
(Figure 10.3).
The saw uses fresh water which drains into sump below the floor before
decanting to the creek.
The core is cut and placed back into the core box.
The core box with cut core is returned to the core shack for sampling.
• The geologist and technician collect the cut core from the same side and
place samples in clean plastic bags with a sample tag. The sample number
is written on the outside of the sample bag.
• QA/QC samples are inserted into the sample stream at prescribed intervals.
Full description of the QA/QC program is provided in Section 11.0.
• Five samples bags are placed in rice bags and a record is made of the
sample number placed in each rice bag.
• The core is stored on core racks inside a secure building or shipping
container on the Property which has a full time security guard living on site
(Figure 10.4 and Figure 10.5).
