Thank you Walt...it's been awhile. :-)

I agree about the Snap rock being much more competent than the Lac de Gras samples I've seen and fondled.

However...I suspect that the Snap Lake ore falls in that 'grey' area, where we can mull it over, and discuss it much...but in fact could go either way.

There is possibly more advantage to drift and fill method in any case, I think. What say you?

Regards,

Will

Walt, F.P. and others have commented in a generally less than optimistic manner regarding the size potential of kimberlite/lamproite dykes.

Do you recall the ultramafic lamprophyre dyke at the Con Mine in Yellowknife. True, not a kimberlite nor a lamproite, but according to some (N. Rock among others) part of a larger "family" of ultramafic alkaline intrusions that includes kimberlite. The Con Mine lamprophyre contains diatreme facies, has been traced for several kilometers in strike and dip, and averages 4 meters in width, although occasionally it can be up to 30 meters wide.

I guess one shouldn't assume that ALL dykes are thin and therefor not viable targets.
