Gold intersection 15.97g/t Au Across 32.1 m - Roxmark reports hardrock tenacity zone drilling continues to return high-grade gold

    TORONTO, April 29 /CNW Telbec/ - Roxmark Mines Limited (TSXV-RMK) today
reported high grade results from the ongoing drilling program being carried
out on the Hardrock Project joint venture in Geraldton, Northwestern Ontario
by Premier Gold Mines Limited as operator.
    Drilling at the Hardrock Project continues to return high-grade gold
mineralization in the Tenacity Zone. Initial drilling has been focused on
defining potentially open pit-style mineralization which is being confirmed by
intersections of up to (un-cut) 15.97 grams per tonne gold (g/t Au) across
32.1 metres (m) and 2.38g/t Au across 23.0m. Drilling is now directed on
extending the Tenacity Zone down plunge to follow-up on recent intersections
of up to 16.86g/t Au across 5.5m. Highlights of recent Tenacity drilling
include:

        - The potential to develop both open pit and underground resources;
        - Extremely high-grade gold with individual samples returning assays
          of up to 688.0g/t Au (20.1 ounces per ton gold) across 0.7m;
        - The intersection of a second near-surface mineralized horizon
          located along a similar geological contact.

    Follow-up drilling at Tenacity, as well as the testing of other target
areas, is ongoing.
    The Tenacity Zone is marked by moderately to intensely silicified and
veined greywacke host rocks, adjacent to a folded ultramafic rock unit.
Mineralization consists of pyrite, pyrrhotite, arsenopyrite, and minor visible
gold. Drilling has confirmed potentially open pit-style mineralization over a
minimum strike length of approximately 500 metres, and is now testing for
higher-grade mineralization that could be amenable to mining from a ramp below
the potential pit workings. Mineralization remains open at depth with some of
the strongest looking mineralization being identified from the western-most
(down-plunge) sections drilled to date. Hole TN026 (15.97g/t Au across 32.1m)
tested the Tenacity Zone up-dip from an historic intersection that returned
49.3g/t Au across 4.3m, and down-dip from an historic intersection that
returned 3.8g/t Au across 32.7m.

    Recent drilling has intersected a parallel mineralized zone (assays
pending) located in a geological setting (ultramafic contact) similar to and
south of the main Tenacity Zone. Hole TN052 collared into mineralization at
10.9m, and intersected more than 40.0 metres of veining, alteration and
sulphides characteristic of Tenacity. An exploration hole (HR008) drilled from
the ice several hundred metres east of this new intercept collard into similar
mineralization that assayed 2.51g/t Au across 4.9m. Follow-up drilling to test
this potential new discovery will commence upon receipt of assays.
    These results at Tenacity continue to support the operator's belief that
historic and new results will be utilized in an NI 43-101 compliant mineral
resource estimate, which is to be completed in Q4 2009. The current program at
Hardrock is expected to consist of more than 50,000 metres of definition and
exploration drilling.
    Importantly, the Hardrock Project has the potential for defining several
styles of mineralization capable of hosting resources, with grades and widths
similar to many of Ontario's major gold mines including:

        1) Open pit-style mineralization with grades exceeding 1.5 g/t Au
           (Timmins, Hemlo)
        2) Broad zones of mineralization with grades averaging 5.0+ g/t Au
           (Musselwhite)
        3) Narrow vein zones with higher gold grades often exceeding 7.0g/t
           (Red Lake, Pickle Lake).

    The Project is operated by Premier Gold Mines Limited (TSX-PG) under a
joint venture in which Premier is earning a 70% interest and Roxmark has a 30%
carried interest The Hardrock Project is host to several past-producing mines
which collectively produced more than 2.0 million ounces of gold from the same
deposits to shallow depths of some 2000 feet (600 metres) from 1938-1968. The
mined zones remained open at depth at the time mining ceased and developed
historical resources were left in place within the existing mine workings. (A
qualified person has not done sufficient work to verify the historical
resource, the Company is not treating the historical resource as a current
resource and the historical resource should not be relied upon).
    The Project offers development advantages with the Trans-Canada Highway,
Trans-Canada Pipeline, and major power lines running through the center of the
property. Significant potential exists for developing resources in several
areas including: open pit-style mineralization at the site of the original
discovery where a resource containing several hundred thousand ounces of gold
was partially drilled off by previous operators; several newer high-grade
discoveries that have been made throughout this large property package that
have received little to no follow-up; resource blocks reported to remain
within the mine workings; and the main mined zones which remain open below the
600 m level.

sent to Activation Laboratories, an accredited mineral analysis laboratory in
Thunder Bay, Ontario, for preparation and analysis utilizing both fire assay

    The Hardrock Project is located in the heart of the Beardmore-Geraldton
Greenstone Belt, a highly prospective high-grade gold district that has seen
relatively little exploration over the past several decades.
