John Dern president and general man
ager of the Lower Mammoth company.
and Mans II. Coffin, who Is a brother OF
II. c. Coffin. who is superintendent OF
the company, returned early Saturday
morning from Tintic. where they made
an overnight inspection OF the prop
erty They returned with some magnih-
cent samples OF the ore now being found
on the 2000-foot level. the ore showing
enough gray copper alone TO constitute
IL shipping grade without demanding any
assay test
Mr. Dern was delighted with the Lower
Mammoth conditions al depth, but hc
was fastening home when seen by The
Tribune. and asked that Mr.. Coffin be
seen, as he would back up everything
that Mr. Coffin had to say.
Mr. Coffin said that the best results
in the history OF the property are now
due, for the light oNidtzed zone has given
foot OF the lattor being as heavy as
three or four cubic feet OF the upper ore.
For the first time in years. Nh. Coilin
is willing TO admit that the Lower Nam
has what he calls character: and looks
as II il will open big and rich.
In drifting south from the shaft on
The 2O0O- foot level. the face, several days
ago. broke into rich ore This better
ment was especially strong TO the cast
or left side of the drift. Superintendent
Coffin continued the drift, so as TO bring
the east side Just to the ore. not caring
TO mix waste and pay rock together
Instead OF continuing due south. how
ever, the ore turned slightly 10 the south
east. so the drift describes a slight arc
In that direction At a point about thirty
five feet southeast of where the first rich
orc was found the drift struck a hneiy
defined wall of a fissure that is trend
ing from northeast TO southwest.
Whether or not this is the noted Lower
Mammoth east nssure depends on future
development work. but II is the conVic'
tion of Mr.. Coffin that the drift has beer
paralleling n big ore body for the thirty
FIVE feet mentioned. and that the ore
body proper lies along the new hsSur'
northeast from the point where the drit
encountered the assure. As PROOF o
this theory. the management is cross
| cutting into the orc at a point very neal
where the first high grade values were
| encountered. and where from elshteel
inches to two feet OF rich rock wer'
expected. Up TO the present time The

for over six feet, and the face still holds
