Channel samples return values up to 36.40 g/t Gold - Roxmark expands new high-grade gold discovery at Northern Empire Mine property

    TORONTO, July 23 /CNW Telbec/ - Roxmark Mines Limited (TSXV-RMK) today
announced that its 2009 surface exploration program at the Northern Empire
Mine property has returned further encouraging results, including values of up
to 36.40 g/t of gold in newly completed channel sample assays.
    The main structure has a strike length of 1.5 km of which 900 metres have
been stripped and sampled. This structure is a well mineralized gold bearing
zone with various degrees of alteration containing disseminated arsenopyrite,
pyrite and chalcopyrite. The south structure, located about 200 metres south
of the main structure, consists mainly of quartz veins and has been explored
for a total of 600 metres. Both structures are open at both ends.
    The new structures, parallel to the Power and Contact Zones, were
outlined in a 2008 High-Resolution Aeromagnetic (HRAM) airborne geophysical
survey. They lie 240 metres south of and parallel to the NI 43-101 resource as
reported in November 2008. A diamond drilling program of at least 3,000 metres
will be undertaken in August following completion of the surface work.

    Selected highlights of the current sampling program are detailed below:

    Peter Bevan, P. Eng., consulting geologist, is the Qualified Person for
the information contained in this news release and is a Qualified Person
within the meaning of National Instrument 43-101. Assay results are from
samples sent to Activation Laboratories, an accredited mineral analysis
laboratory in Thunder Bay, Ontario, for preparation and analysis utilizing
both fire assay and screen metallic methods.
    "These new results bring additional momentum to our program at the
Northern Empire Mine property," said Monir Younan, Roxmark President. "One of
our major objectives for 2009 is to delineate additional gold resources at the
mine - resources that would add further momentum to our development plan."
    The Northern Empire Mine is located in the Town of Beardmore,
approximately 200 km northeast of Thunder Bay and serviced by the Trans-Canada
Highway. It was operated successfully by Newmont Mines from 1934 to 1941. The
mine was serviced by a shaft to a depth of 2,460 feet and produced 149,000
ounces of gold from 426,000 tons of ore at a recovered grade of 0.35 oz/t Au.
The on-site 200TPD mill (expandable to 500TPD) was built in 1982 and upgraded
and permitted by Roxmark.
    Roxmark's current plan is to develop the eastern strike length of the
Northern Empire mine by a decline and mine the area to the second level. A
preliminary study indicates that production can begin within six months of
completing development work. This program will be followed up by dewatering
the shaft and installing a headframe, hoist and ancillary equipment on surface
and underground.

    About Roxmark Mines

    Roxmark Mines Limited is the leader in gold and molybdenum exploration
and development in the historically significant Geraldton-Beardmore area of
Northwest Ontario. In addition to the Hardrock Project in the Geraldton Camp,
Roxmark is pursuing a number of initiatives in the Beardmore Camp, including
re-opening the Northern Empire Mine and its onsite mill and expanding the
resource base at the Leitch-Sand River Mine. In recent years, Roxmark has
generated cash flow from bulk-sampled gold and molybdenum processed at its
fully-permitted mill and has the advantage of infrastructure from nine
formerly highly productive gold mines located on its properties. These mines
previously produced nearly four million ounces of gold from high-grade ore but
were closed primarily due to boundary issues and dramatically lower gold
prices at the time.
