Trigon provides update on Henry Mountains Project in Southern Utah

    KELOWNA, BC, March 20 /CNW/ - Trigon Uranium Corp. (TSX-V:TEL; "Trigon"
or the "Company") today provided an update on its Henry Mountains Project
located immediately west of the Bullfrog and Tony M uranium deposits of
Denison Mines Corp., and the Frank M uranium deposit of Uranium One Inc. in
southern Utah.
    From the perspective of resource prospectivity, the results to date
support Trigon's belief that the known mineralized trends extend onto its
Henry Mountains property. An analysis of historical data from the Bullfrog
deposits revealed that the distribution of mineralization in the Company's
first four drill holes is consistent with the mineralization of the
neighboring established deposits.(1)
    Exploration drilling in 2007 was designed to test one of several target
areas, including "Area 1", with high potential to host uranium mineralization
similar to that of the neighboring deposits. All of the first four holes
drilled at Henry Mountains intersected uranium mineralization, including one
(HM07-03) strongly mineralized hole (see press release of November 8, 2007 for
detailed drilling results). The Company then proceeded to move to the next
target, "Area 2", to the northeast where six drill holes centered within 2,000
feet of Trigon's eastern property boundary on a projection of the Bullfrog
Indian Bench-Copper Bench mineral trend of Denison Mines Corp. were planned.
Due to drilling fluid losses caused by shale water absorption and possibly
vertical fractures at the northernmost holes, the program was interrupted in
the 6th hole in order to re-engineer the drilling methods. The required study
and analysis has been completed. The Company has determined that drilling
costs can be reduced by utilizing 24-hour around-the-clock drilling to
minimize the time during which drilling fluids are in contact with the shale
walls, and by working with a diverse suite of drilling fluids available to
deal with changing stratigraphic conditions as drilling progresses.
    The Company considers it desirable to carry out an extended drilling
program at the Henry Mountains Project. It is generally recognized that the
source area for the Salt Wash Member of the Morrison Formation (which is being
drilled for Uranium in the Henry Mountains) was deposited as a braided stream
system with many frequently shifting northeast/southwest channels. Uranium and
vanadium mineralization occur in thicker portions of the sandstone channels in
association with residual carbonaceous material. The plan view of known
drilled out ore bodies resembles a meandering stream with a major split north
of the Tony M mine of Denison Mines Corp. A projection of this system crosses
Trigon's land in a northwest direction from the Indian Bench Deposit, and is
the basis for the 2008 exploration program.
    The Company is now detailing an extended drilling program which should
include several lines of holes perpendicular to the projected strike of the
mineralized channel. The Company believes that the next drill program should
encompass three drill lines. These are: (1) a line of holes along the eastern
edge of the claim blocks, approximately 2200 feet west of the western edge of
the Indian Bench deposits; (2) a second line in the "Cow Flat" area where the
first four holes were drilled with good gamma-logging-eU3O8 results 2; and
(3) a third line of holes, in an area approximately one and one-half miles
west of the Cow Flat area. All of the holes would fall within Trigon's
projection of the mineralized channel.
    The proposed drill program will economize with respect to spreading the
fixed costs (road building, environmental work, etc.) over the number of
proposed holes. The program is also consistent with the scope of drilling
required to advance the Henry Mountains Project at an effective chronological
pace. As the program will involve an area in excess of 5 acres, an extended
environmental application to both state and federal regulators may be required
prior to the commencement of the next phase of drilling. (Planned drill areas
of less than 5 acres are generally reviewed and approved by state and federal
regulators without recourse to public comment. Larger area drill programs may
require avenues for public comment, and therefore extended approval time
lines.) The environmental program approvals process will begin once lands
affected by the first drilling program have been fully reclaimed and approved
by the regulators. The Company estimates that reclamation is approximately 50
per cent complete to date. Trigon's working capital available is approximately
C$2 million dollars. This amount is adequate to fund operations and
exploration. However, given current market conditions the Company is giving
consideration to joint-venturing the Henry Mountains Project prior to the
resumption of drilling.

    (1) The historical data was summarized prior to the introduction of
        National Instrument 43-101 and therefore should not be depended upon
        by shareholders and is not depended upon by Trigon. Trigon has used
        this general historic information to assist with evaluation of broad
        geological conditions related to uranium mineralization in the Henry
        Mountains area.

    (2) The technical information in this news release has been reviewed by
        Mr. Stuart Havenstrite, CPG, Technical Advisor to the Company and a
        Qualified Person as defined in National Instrument 43-101. Drilling
        on Trigon's Henry Mountains property is carried out by Diversified
        Drilling LLC of Missoula, MT. Gamma logging for equivalent uranium
        grades is performed by Century Geophysical Corp. ("Century") of
        Tulsa, Oklahoma using a Century-built 9057 logging tool. The tool is
        calibrated for k-factor and dead time using U.S. Department of Energy
        test pits. Century's Compu-Log software is used for calculation of
        equivalent uranium grades.
