Roxmark Intersects High-Grade Gold Mineralization at Northern Empire Gold Mine

Toronto, Ontario, May 21, 2008.  Roxmark Mines Limited (TSXV - RMK) today provided an update on the Diamond drilling program currently being carried out on its Northern Empire Gold Mine property.

Gold mineralization has been encountered in every hole drilled along the strike length in the Contact and Power Zones. In addition to these two zones, gold mineralization was encountered in the Iron Formation Zone (I.F.) which has returned significant assays and in the Foot Wall Zones (F.W.). Results as high as 60.50 grams per tonne gold (g/t Au) (1.760 opt) over 0.4m and 34.50 g/t Au (1.010 opt) over 0.4m were encountered.  Although assay results and infill samples are still awaited, the following are significant assays received to date:

                NOTE:  True widths estimated at approximately 70% of intersection width

The planned 6,200-metre program, which began in March and was designed to test 1,250 metres of mineralization strike length at the property, is expected to be extended beyond 8,000 metres. Early in the year, Roxmark announced a National Instrument 43-101 compliant report outlining resources for a limited strike length from section 7+00E to 9+00E to a depth of 100 m.  The 2008 drilling was planned to delineate the mineralization west of the resource area on the Contact Zone and in certain areas on the Power Zone.

The drilling program is supervised by Peter Bevan, P. Eng., who is the Qualified Person for the information contained in this news release and within the meaning of NI 43-101.  The program utilizes a Quality Assurance/ Quality Control Program consistent with NI43-101 and best industry practice. The NQ core is logged, sampled and split. The samples are recorded, bagged and sent out to Actlabs Group of Companies and to S.G.S. Lakefield Research Limited, both accredited mineral analysis laboratories, for preparation and analysis utilizing both fire assay and screen metallic methods. To date, minor check sampling has been carried out and more is planned.

The Northern Empire 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 mine hosts an on-site 200TPD mill (expandable to 500TPD) which was built in 1982 and upgraded and permitted by Roxmark.  It processed gold and molybdenum ores in 2005 and 2006, respectively.  Following the recommendations of the Bevan Report, Roxmark's objective is to recommence gold production at the Northern Empire Mine after successfully delineating extensions to the Contact Zone in the 2008 program.  A study of the feasibility of re-opening the mine will include dewatering historical workings, drifting in the Power and Contact Zone vein structures, completing a 5,000 ton underground bulk sample, and carrying out closer spaced resource identification drilling from available underground workings to the east and west of the historical shaft.

The Northern Empire property is located in the Town of Beardmore, approximately 200 km northeast of Thunder Bay and serviced by the Trans-Canada Highway.  Accessibility of all Roxmark properties, including the Leitch Gold Mine and the Nortoba-Tyson (a new source of gold and molybdenum), is a strong cost and logistical advantage. 

Roxmark holdings are located in the Beardmore-Geraldton greenstone belt, a highly prospective high-grade gold district that has seen relatively little exploration over the past several decades.  The belt has seen historic production of more than 4.1 million ounces of gold.

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 the last two 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 six formerly highly productive gold mines located on its properties.  These mines previously produced nearly two million ounces of gold from high grade ore but were closed primarily due to dramatically lower gold prices at the time and to boundary issues, since eliminated.
