After reading the NR for a second time, I came upon this statement that "Phase-Two is still in the planning phase but will likely consist of 11 HQ core holes: Two holes within the resource will test down-dip mineralization and provide infill drilling for upgrading of the resource."
These two holes within the resource are considered infill because they are not stepping out and this means they can upgrade the category of ore from inferred, to indicated, measured etc.
This could be the most rewarding part of the phase 2 drilling campaign with a potential expansion of the resource; if the resource calc is only to 400 ft at this time, and PEM drills to 800 ft (400 ft further and down dip), with success you can begin to justify assuming that the ore is consistent to the 800 ft level and start to double the resource. JMO LOL Joe.
