Earlie:
1) recently released results have a number of ore grade (but not width) intersections (ie. 7.42%Cu-2.62%Zn/1.73m in hole 98-12 on Section 8100) spaced quite a distance apart (section 10,400 has hole 98-11 assaying 4.77%Cu-0.89%Zn/0.55m). This is 2.3km! on the same "active" horizon. Unlike Gold deposits, when an ore grade intersection is hit in VMS, but is thin (ie. metre-scale), then it's a pretty sure indication you're on the fringe of the MOTHER. Drill deeper, drill off to the sides (~100m) and you'll get thicker ore grade intersections.
2) VMS indicators they're probably using to vector-in to the Deposit(s) are:
- thickness of "active" horizon: the thicker the better
- Cu\Zn ratio of intersection: more Cu, closer to source
- size of volcanic fragmentals: the bigger the frags, the closer to the original volcanic vent area, the hotter/copper-rich the mineralizing fluids
- geophysical response: don't forget "lone" conductors stacked above/below an active horizon
- alteration mineralogy and chemistry: more chlorite (or Magnesium-rich equivalents), the better
3) there's just so much one can read in the latest press release, but the fact of so many good intersections over such a large area, argues strongly for the presence of a VMS Camp, such as Noranda or Timmins: the physical scale is the same here too (~10-20km). Falconbridge/NAR has it ALL! |
