Subject: dykes and ring dykes
Willp, I forgot the last part of your
post.....I changed my mind because I
came to the realization that the dykes at
Snap Lake were not typical ordinary
type II kimberlite dykes like those
mined in South Africa. For those who
don't know, the SA dykes are best
described as groups of en echelon to
anastomosing, near verticle, interwoven
lenses, averaging 60-80 centimeters in
width, which pinch and swell along
strike. In the simplest case, one lens
pinches out, and the next is located to
the side of the first, offset by several
meters. This sort of situation didn't
appear all that attractive to me.
However, the dykes at Snap Lake are
clearly distinct in terms of morphology
and mining implications and most
importantly, tonnage implications. The
grades at Snap Lake are not out of the
ordinary. Briefly, you now know why I
changed my mind and got out my check
book to go long on the stock. regards,
teevee
