Core Drill Will Help
to Determine depth n

Probably no other agency will become great
a factor in the prospecting of the quartz lodges

depth at which will be struck.
The promoters of the drill company realized
that if capital be induced into the dis
trict for the development of the quartz properties
it must first be demonstrated that those proper
ties had depth" and that this knowledge could
be most readily acquired through the use Of
drill capable of sinking rapidly and taking out
core that would reliably indicate the strata to be
encountered. So. it may be said that the project
combined certain amount of philanthropy with the
undoubed commercial benefits that will surely
crue.
A certain amount of stock placed the

The field Of core drilling has been predominated
f geaGs by The diamond drill; in fact, core drill
and diamond drill were at one time Synonymous

it was predicted that it would be used for boring
large holes for blasting and similar purposes. and

diamonds however. has so increased the of

The shot process is the cheapest and most rapid
method for drilling deep holes of large size up to
80 inches in diameter. If such work were under
taken with diamond drill the cost of the bit alone
would be several thousand dollars, The Calyx

considered the best the market is designed to
