Barker Reports Further Sample Results From Recent Besshi Massive Sulphide Discovery

Vancouver, B.C., March 4, 2005 -- Barker Minerals Ltd. (BML - TSX/V) is pleased to follow-up, further to its earlier news release, also dated March 4, 2005, with the release of its second set of sampling of the Besshi type mineralization discovered in its recently completed drill program on its Frank Creek Project.

The second set of sampling was undertaken at the recommendation of Dr. Trygve Höy, 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. Most selected mineralized intervals were sampled from the remaining half core, which was sawn in half, with one quarter sent for analyses to Activation Labs and the other quarter remaining in the core box for future reference or studies. A few samples were also taken from drillcore where no samples were previously taken.

The second set of sampling revealed a copper, silver and gold tenor, along with a nickel, chrome, iron, sulpher and cobalt association, which are consistent with Besshi type mineralization. Trace elements arsenic, antimony, tin, indium, bismuth and cadmium are also indicative of sediment hosted massive sulphide mineralization. A number of sulphide zones appear to be massive sulphide layers, and disseminated mineralization may be intensely disrupted and transposed feeder zones. However some of these zones may also be late mineralization, superimposed by late faulting that is obvious in some of the core.

The breccias and conglomerates are difficult to interpret, some clearly look like sedimentary breccias, with rounded milled clasts. If this is the case, then the clasts of sulphide, particularly those with remnant sulphide laminae, are critical evidence for the conclusion that some of the mineralization formed by seafloor "Besshi" type VMS deposition. Some clasts may have also been formed in hydrothermal vents. The intensity of alteration and sulphide mineralization in these zones, similar in character and composition to the massive sulphide layers, imply early formation during massive sulphide deposition rather than mineralization related to late faulting. In summary, it is possible that the breccia-conglomerates record a mixture of discordant, mineralized feeder zone mineralization as well as formation as sedimentary conglomerates, perhaps along seafloor scarps or as "mud volcanoes".

Alteration is intense around much of the mineralization, and includes pervasive sericite, more local silicification, chloritic alteration and possibly albite development. It is probable that the sericite alteration is considerably more widespread and could be used as an exploration guide in locating additional mineralized zones.


The presence of 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 polymetallic 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 follow-up drilling.

Dr. Trygve Höy PhD., P.Eng., a Qualified Person as defined under National Instrument 43-101 ("NI 43-101"), has reviewed the disclosure herein for the purposes of compliance with the requirements of NI 43-101.

Over the past ten years Barker Minerals has acquired and advanced exploration on its over 277,000 acres of mineral properties in the Cariboo Mining District, which is located along the Cariboo Gold District, one of the most mineralized belts in British Columbia. The company has 18 projects at various stages of the exploration process, with 5 projects having defined drill-ready gold targets and precious metal bearing, massive sulphide targets on its 100% owned properties.
