Subject: Jspec's perspective

I concur with what jspec concludes from
his analysis of dips (posted elsewhere).
The possible modification to his model
that may reduce the estimated tonnage
from immense to only extremely large
involves anisotropy in the country rock
(fabric direction, fractures, different
rocks) or some other reason for an
asymmetrical development (ie, west-side
only) of the cone sheet.

For interested readers there is a recent
article in Geology (March 1999, v.27,
p.207-210) on cone sheet formation on
Gran Canaria, by Schirnick, van den
Bogaard, and Schminke. Their dike rocks
are phonolite-trachyte. They conclude
that cone sheet development resulted
from episodic replenishment and
expansion of a laccolith-like magma
chamber at shallow depths, rather than by
magmatic overpressure as magma enters
the shallow crust. If the former is possible
with kimberlite magmatism, the tonnage
potential increases substantially even
beyond the cone sheet. I think teevee
would agree.

Gareth,

If there is a lacolith or lopolith like
magma chamber under the Snap
Lake cone sheet, and if it has
commensurate grades with the
mini-bulk sample, a $100.00 per
share (post split) would not be
unreasonable.....Snap Lake would
then rank the diamond discovery of
the millenium.
