TORONTO, July 21 /CNW/ - DUMONT NICKEL INC. (DNI:TSX-Ven) is pleased to
announce that its 24 hole reverse circulation drill program at the Cane
Springs Property, Utah, reported gold sections from strategic locations all of
which merit further follow-up by additional drilling and surface work.
Sections of interest range 0.2g/t to 30.3g/t gold over 3.1m to 15.2m (10ft to
50ft) long drill intercepts.
The 24 inclined holes (total 1,036m, 3,400ft) were collared over the
flank, and on trend, of the Cane Springs Historic Gold Mine to probe
subsidiary zones suggested by surface work. Holes were spaced some 40m apart
on a 40x20m grid. Some of the holes were collared to also test locally gold
bearing silica breccias flanking the sedimentary package hosting the Historic
Mine.
Two of these holes, drilled on trend from the Cane Springs Historic Gold
Mine workings, returned good gold grades from a previously unexplored
structure provisionally interpreted as either a new gold zone or an offset
extension of the main zone of the Historic Mine. An additional two holes of
interest are located over the Mine, approximately 35m (100ft) above the
uppermost level mined.

Initial gold assays from many other holes also reported gold ranging
0.2g/t to 1g/t from short intervals ranging 1.5m to 3.1m (5ft to 10ft) all of
which are being cross-checked and interpreted. Given the geometry and
characteristics of the payzone at the historic Mine, these intervals are
considered to be indicators of nearby gold mineralization.
DUMONT's 2003 core drilling on trend eastward from the Historic Gold Mine
had reported also up to 14.9g/t silver and 0.8% copper from some of the gold
bearing sections as had also independent third party surface sampling adjacent
to the Mine which reported up to 5% copper (accompanying 6g/t gold). Analyses
for silver and copper from the current drilling (on trend to the west) are
pending.
The Cane Springs Mine produced gold during the late 1800's and early
1900's from a high grade subvertical shoot in marble (skarn) intruded by
monzonite. Underground workings extend down to 240 feet below surface, and
consist of four short levels accessible by two shafts, although the ore zone
was mined only down to the 147 foot level below surface as activities were
abruptly curtailed by events leading up to the Second World War. Production
was never resumed.
Historical records indicate that at least 60,000 tons were mined with
boxcar grades ranging 16g/t to 288g/t gold (0.5 to 9.0 oz/ton) occurring in
visible native form amenable to free milling. Ore faces from the third and
fourth levels are reported to have typically assayed approximately 48g/t gold
(1.5oz/ton) with 32g/t to 44g/t silver (1 to 1.4oz/ton), and pillar material
in the lower levels to have typically ranged 108g/t to 291g/t gold (3.4 to
9.1oz/ton). Records also indicate that active mine headings terminated in ore.
Historical surface sampling records from the vicinity of the Mine report
good grade gold from trenching across a multitude of shear zones which have
not previously been explored below the surface. Records also propose that the
pay zone mined is one of a pair of zones, and that the "sister" shoot was not
developed nor explored.
DUMONT's findings to date are consistent with historic records suggesting
the presence of good grade gold zones yet to be discovered in the vicinity of
the Historic Mine. These are considered to be very encouraging findings given
that localities away from the Mine have not previously been adequately
explored, especially below the surface.
The Cane Springs Property comprises 580 acres designated a Special
Project Area under the terms of DUMONT's Utah Joint Venture with Clifton
Mining Company (CFTN:USOTC) and Woodman Mining Company. DUMONT may earn a 50%
interest in the Property by spending US$400,000 by December 2005 (US$370,000
spent to date). Following earn-in, the parties will jointly fund future work
pro-rata to their respective interests.

EWIT PROJECT DRILL PROGRAMS
The reverse circulation drilling program at the Kiewit Project Area was
concluded in early June after completing an aggregate of 3,479m (11,342ft) in
33 holes. Highlights from 24 of these holes were previously announced
(April 27, 2005). The remaining seven holes were drilled at the Midzone and
the Rainbow Hill areas, and though they intersected stockworks, the drilling
pattern and poor drilling conditions do not permit definitive extrapolations.
Work on these areas will continue.
A total of 1,795m (5,880ft) were completed during June in 17 core holes
at strategic locations mostly over the southern portion of the Project Area
over the Kiewit Historic Gold Zone. The holes included infill drilling at
localities which had proven difficult for the RC drill rig. Results from this
work are pending as much of the core is still being logged and split.
The 7.5 square kilometer geophysical survey launched over the entire
Kiewit Project Area in June is completed. The survey entailed concurrent
Gradient Array Resistivity and Spontaneous Potential Gradient surveying to
trace the extensions of the stockworks gold zone beneath sediments, and to
support localization of deep drilling targets. Preliminary results from this
work are very encouraging. Details from this work will be announced once
ground verification of anomalies identified has been completed.
DUMONT is encouraged by findings to date from the Kiewit Gold Zone and
will continue its work to define extents of the gold bearing portions and to
better define the higher grading sections. Plans are to resume drilling once
all of the data gathered thus far have been consolidated and interpreted.
