Barker's Drill Results Confirm Besshi Massive Sulphide
Discovery At Frank Creek

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - March 4, 2005) - Barker
Minerals Ltd. (TSX VENTURE:BML) is very pleased to report that the drill
results on its Frank Creek Project discovered Besshi type mineralization
in five of seven drill holes. (Besshi deposits -
http://www.barkerminerals.com/s/Glossary.asp)

The drill program was designed to test the mineralization discovered in
the 2004 trenching program and to test nearby anomalies detected by the
recent Titan geophysical survey. Drilling intersected significant
intervals of hydrothermally altered, sedimentary rocks hosting stringer
to semi-massive copper plus or minus zinc-rich sulphides. The alteration
and mineralization revealed in the drill program, which was undertaken
late in 2004, are consistent with a feeder system to a Besshi-style
massive sulphide system.

The prevalence of altered rocks with stringer and locally semi-massive
and massive sulphides demonstrates the highly prospective nature of the
Frank Creek Project for highgrade polymetallic massive sulphide
deposits. Individual summaries of the five drillholes that intersected
sulphide mineralization are set out below. The drillhole parameters
(http://www.barkerminerals.com/i/pdf/drill_parameters.pdf) and drill
plan map (http://www.barkerminerals.com/i/pdf/fc_ddh_model.pdf) are
posted on the Company's website www.barkerminerals.com. Drill hole
sections will be up-loaded to the website once completed.

A second set of sampling of mineralization was undertaken at the
recommendation of Dr. Trygve Hoy, PhD., P.Eng., a Qualified Person under
National Instrument 43-101, to better determine the grade, tenor,
mineralogical associations and to characterize the various individual
bands or zones of mineralization within the wider altered zones. These
results will be released in a subsequent news release.

Drillhole Summaries

FC04-07, a 487 metre drillhole, targeted two shallow to mid-depth
chargeability high/resistivity low anomalies and a deeper 'layered'
anomaly indicated by the Titan geophysical survey. Several altered and
stringer mineralized intervals were intersected. Interval 108.2 to
132.9m comprised of altered sericite phyllite with up to 1% disseminated
pyrite throughout, but local 1-3mm wide stringers of
pyrite-pyrrhotite-chalcopyrite-sphalerite-galena. The following
mineralized interval was intersected:

- 108.2 to 127.2m: 19.0m @ 0.08% Cu, 0.08% Pb, 0.17% Zn including 122.9
to 127.2m: 5.5m @ 0.18% Cu, 0.15% Pb, 0.32% Zn and individual analyses
included the following:



---------------------------------------------------------------------
Sample From (m) To (m) Interval (m) Cu (%) Pb (%) Zn (%)
---------------------------------------------------------------------
212306 109.7 111.2 1.5 .03 .11 .26
---------------------------------------------------------------------
212309 114.2 115.7 1.5 .08 .03 .11
---------------------------------------------------------------------
212317 122.9 124.2 1.3 .53 .23 .49
---------------------------------------------------------------------
212318 124.2 125.4 1.2 .15 .31 .68
---------------------------------------------------------------------
212319 125.4 127.2 1.8 .03 .10 .21
---------------------------------------------------------------------


- interval 299.4 to 310.8m comprises sericite greater than
chlorite-altered quartz-feldspar-rich sandstone with disseminated pyrite
throughout with locally stronger pyrite-chalcopyrite-sphalerite stringer
mineralization. A higher grade mineralized interval was intersected at:

- 307.5 to 309.5m: 2.0m @ 0.69% Cu, 0.05% Pb, 0.20% Zn which included
the following individual analyses:



---------------------------------------------------------------------
Sample From (m) To (m) Interval (m) Cu (%) Pb (%) Zn (%)
---------------------------------------------------------------------
212342 307.5 308.4 0.9 1.28% 0.04% 0.07%
---------------------------------------------------------------------
212343 308.4 309.5 1.1 0.21% 0.06% 0.30%
---------------------------------------------------------------------


FC04-08, a 445 metre drillhole, targeted a large coincident
chargeability high/resistivity low centred at approximately 17+50W, and
a smaller near-surface IP anomaly. Numerous moderately sericite-quartz
plus or minus chlorite-altered intervals containing up to 5%
disseminated and stringer sulphide mineralization (pyrite greater than
chalcopyrite-sphalerite-pyrrhotite) were intersected. Interval 103.2 to
109.7m comprises interbedded black argillite, siltstone and fine
sandstone with patches of siliceous alteration and up to 5% disseminated
and stringer sulphides, comprising mostly pyrite with lesser
chalcopyrite, sphalerite and galena. The following mineralized interval
was intersected:

- 103.2 to 109.7m: 6.5m @ 0.13% Cu, 0.07% Pb, 0.18% Zn, including:

- 106.7 to 108.2m: 1.5m @ 0.26% Cu, 0.3% Pb, 0.23% Zn.

Drillhole FC04-09, 129 metres in length, was designed to test the
down-dip extension of sulphide mineralization discovered in a nearby
trench as well as in subcrop and boulders. The interval from 18.4 to
29.8 metres comprises weakly to moderately quartz-chlorite-altered
quartz-rich sandstones and siltstones containing up to 2% disseminated
to stringer pyrite greater than sphalerite greater than chalcopyrite as
well as a 0.5 metre interval of massive sulphides from 22.3 to 22.8
metres which assayed 0.58% copper, 0.15% lead, 6.57% zinc and 1.7 grams
per ton gold. Significant intersections within this altered and
mineralized interval included:



---------------------------------------------------------------------
Sample From (m) To (m) Interval (m) Cu (%) Pb (%) Zn (%)
---------------------------------------------------------------------
212388 21.4 22.3 0.9 .02 .04 .11
---------------------------------------------------------------------
212389 22.3 22.8 0.5 .58 .15 6.57
---------------------------------------------------------------------
212390 22.8 24.3 1.5 .02 .04 .26
---------------------------------------------------------------------


Drillhole FC04-12, 236 metres in depth, was drilled 90 metres east, and
along strike, from the mineralization encountered in the 2004 trenching
and in drillhole FC04-09; the upper part of this drillhole encountered
similar geological units to those in FC04-09 and FC04-10. A zone of
disseminated to stringer pyrite-pyrrhotite greater than
sphalerite-chalcopyrite was encountered from 12.7 to 26.7 metres within
disrupted, altered siltstone and sandstone. This interval included:

- 15.7 to 19.0m: 3.3m @ 0.48% Cu, 0.05% Pb, 0.10% Zn including:

- 18.3 to 19.0m: 0.7m @ 1.78% Cu, 0.06% Pb, 0.23% Zn

Drillhole FC04-13, 444 metres in length, was drilled between drillholes
FC04-07 and FC04-08 to test an IP chargeability high/resistivity low. A
sequence of interbedded quartz-feldspar sandstone, siltstone and
argillite similar to previous holes was intersected. Most significantly,
a wide interval of sericite-altered sandstone and siltstone/phyllite was
intersected over 70 metres, from 222.2 to 291.5 metres; this unit is
similar in style to the altered sediments intersected in the upper 100
metres of FC04-08. The altered zone contained disseminated and stringer
sulphides throughout, reaching up to 10% in places, with narrow
semi-massive/massive sulphide intervals. Pyrite and chalcopyrite were
most common with lesser sphalerite and pyrrhotite. A 0.2m band of
massive chalcopyrite-pyrite-sphalerite was intersected at 257.6m. The
most significant continuous interval of mineralization occurred from
257.1 to 268.5m: 11.4m @ 0.8% Cu, less than 0.01% Pb, 0.10% Zn,
including the following:

The alteration and mineralization encountered in the 2004 drill program
at Frank Creek is consistent with a stringer or feeder system to a
Besshi-style massive sulphide system. The presence of these altered
rocks with stringer and locally semi-massive and massive sulphides is
very encouraging and demonstrates the highly prospective nature of the
Frank Creek area for highgrade base metal massive sulphide deposits.
Ongoing lithogeochemical and geological interpretations are being
conducted in an effort to determine the relationship of the
mineralization and the host stratigraphy; these results will be
integrated with the recent Titan geophysical data to produce a 3-D
geological model. This work is aimed at outlining a preferred
stratigraphic horizon favourable for mineralization that will provide a
focus for future drilling.
