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.
