technical report on the nechalacho deposit, thor lake project ...

such as Illimausaq in Greenland, a new lithological code was produced using, as a basis, the
recognizable precursor lithologies. This has greatly advanced the understanding of the
lithology, mineralogy, and to a lesser degree the petro-genesis of the deposit.
After all tests and core observations are completed, and prior to splitting, the core is
photographed outdoors using a hand-held digital camera. Meterages and hole number are
marked so as to be visible in all photos. Core is generally photographed in groups of six boxes.
Starting in the 2009 summer drill program, drill core was also logged for geo<strong>technical</strong>
characteristics. This was initiated with the guidance of external geo<strong>technical</strong> consultants
(Knight-Piésold Consulting). Some of the holes were logged from top to bottom, while others
were logged above, below, and within the Basal Zone, to determine rock quality characteristics
of both the mineralized zones and country rocks. Efforts were made to select holes with varying
orientations to provide comprehensive orientation characteristics of planar structural features.
The geo<strong>technical</strong> logging was done on core logging sheets and entered electronically in to a
custom-designed Excel spreadsheet provided by Knight-Piésold Consulting. A total of 22 holes
were logged in whole or in part (Table 12-2). Holes which were partially logged included the
Basal Zone and a minimum 10 metre interval above and below.
