are being developed and are proving
up satisfactory. The mill crushed
902 tons Of ore during the week, OBJ
tanning a recovery Of SO per cent. The
mill was stopped for about nine hours
owing to the cleaning of the reser-
voir.
The regular %bi-monthly melt OF the
cyanide precipitates is now on, and
should be finished by tomorrow night,
the result of which will be the pro-
duction of from twenty-five to TWEEN
ty-five bars of bullion, weighing
about eighty pounds each.
390-foot level-The west drift n
der the stope on the Triangle vein
was advanced thirteen feet along
three feet of good ore, with the vein
| showing up strong in the face. A
crosscut, sent south into the hanging
wall of the Slope at a point about
thirty-fve feet above the level, has
lust encountered a vein at the 25-
foot point which shows good values,
but It's width is not known at this
writing, owing to not enough work
having been done. A crosscut will be
started from the level, directly un-
derneath the crosscut from the stope
to intersect the ore body, so that the
vein may be drifted on and develop
ed. Stopping continues on the mair
? Triangle vein. This stope, now BOZ
feet long, Is being carried upward ant
westward. and shows an ore body two
, to eight feet in width which carries
t good milling values,
465-foot level-The west drift OF
9 the Triangle vein was advanced ff
e teen feet on the hanging wall side o
z the vein. The drift is being followe
!. up by Slopes which show from seye
Il to eight feet. all of which is millin
+ ore. with the best values lying on tn
" footwall. The stope on the Marth
It vein has been extended to the cas-
g and exposes an average of two feet {
milling ore. The stope on the Ma
4. donald vein, 1000 feet west of ii
1t shaft. continues to produce from tw
l. to three feet of good sulphide ore.
Ie 515-foot level-The east drift c
Re the Triangle vein was advance
lie twenty-six feet. passing through Il
n rhyolite and into the andesite. II
In vein has been badly broken up, b.
shows high grade values in spots. tt
new west drift started last week on
IN branch of the South vein was e
of tended twenty-one feet, showii
TX about a foot of milling ore in t
he face. The i%nterdrift on the Maedo
he aid vein, 1000 feet west of the sha
h, was advanced eight feet on abo
IT. four feet OF ore, two Of which Is hi
as grade sulphide ore. The Slope
ed the Triangle vein was carried east
a In fifteen feet during the past wee
ng exposing three feet of good MILL
is ore. which is about the average wfd
his Of the ledge. About sixty feet ba
lift of the east end Of this stope a ra
tut is being sent through to the Al
foot level and shows an average
ich three feet of ore thus far.

,od west drift on the South vein was
the tended twenty feet, the face at pT

'ty- pIeking up the ore body west of
low fault. No. Z drift, which has b
the following a vein about 900 feet
'eet OF the shaft, has been sent ah
'om twenty-five feet along an average
irty three feet of ore, carrying mil
