Roxmark Continues to Intersect High-Grade Gold Mineralization at Northern Empire Mine

Toronto, Ontario, June 18, 2008.  Roxmark Mines Limited (TSXV � RMK) today announced additional results from the diamond drilling program completed in May on its Northern Empire Gold Mine property.

The program, which followed up on successful 2007 drilling at the Northern Empire, intersected gold mineralization in every hole with high-grade gold mineralization encountered in several holes along the strike, confirming the nature of gold in the zones.  So far, the 2008 drilling program has covered a strike length of 1,050 metres from section 5+75W to 4+75E, with 8,385 metres completed -- an increase of 35% over the original plan.  The 77 drill holes intersected the Power and Contact Zones and, in several holes, the Iron Formation (I.F.), Foot Wall (F.W.) and Hanging Wall (H.W.) Zones were encountered as well.  Follow-up drilling to delineate the zones will be carried out from existing underground workings.

The initial assessment of the program indicates a minimum of three important areas containing high-grade gold mineralization.  The first extends between section 2+25E to 3+50E, the second from section 0+50E to 1+00E, and the third from 3+75W to 5+75W.  Results as high as 62.27 grams per tonne gold (g/t Au) (1.816 opt) over 1.1m and 137.00 g/t Au (4.000 opt) over 0.5m were encountered.

Several assay results and infill samples are still awaited, but in addition to Roxmark�s news release of May 21, 2008, the following are additional significant assays received to date:

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

A surface program is being planned for summer 2008 to expose additional surface gold mineralization at the Northern Empire.  A number of areas of interest along a strike length of 1,250 metres have been outlined from drilling which require stripping and channel sampling. In addition, Roxmark plans to drill two promising gold showings on the neighbouring Nortoba-Tyson property.

The 2007 Roxmark Northern Empire drilling program was on a limited strike length from section 7+00E to 9+00E to a depth of 100 metres.  The results were encouraging and were incorporated in a resource calculation presented in a National Instrument 43-101 (�NI 43-101�) compliant report issued in January 2008.  In 2006, SRK Consulting was commissioned to digitize available drilling and other information on the mine and to develop a 3D mineralization model which outlined a potential in the range of 150,000 ounces of gold based on historical average grade of 0.35 oz/t Au. The SRK assessment is not NI 43-101 compliant and it is based on insufficient exploration work.

The 2007 and 2008 drilling programs were 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 NI 43-101 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 operated successfully by Newmont Mines from 1934 to 1941.  It 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, and is currently available for custom milling.

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.

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. 

The Northern Empire property is located in the Beardmore Camp near 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 property (a new source of gold and molybdenum), is a strong cost and logistical advantage.

The Geraldton Project

A significant number of Roxmark properties in the Geraldton camp known as the Geraldton Project are under option agreement with Premier Gold Mines Limited (TSX - PG).  As operator, Premier is carrying out a drilling program using three drill rigs currently on the Little Long Lac property.  Discoveries so far have intersected a minimum of six potentially important vein zones:  The Kailey Zone, Main Zone, No.9 and No.10 Vein Zones and two new zones named No.11 and No.12 Vein Zones.  Premier�s Stephen McGibbon, P. Geo., is the Qualified Person within the meaning of NI 43-101 for the information contained in Premier�s announcements.  Results were previously announced in several news releases in 2008.

Currently, drilling is being carried out on the Kailey Zone and on two primary targets, the �Mine Repetition� and the Talmora Anticline Zone (�TAZ�).

The Little Long Lac mine produced more than 600,000 ounces of gold during the period 1934-1953 at an average recovered grade of 11.66 g/t Au.  Drilling results to date suggest that there is a good potential for both bulk tonnage and high-grade mineralization at Little Long Lac. 

At the Magnet Gold Mine, in addition to other known zones, Premier has discovered a new high-grade gold vein zone which returned numerous significant intersections including 67.08 g/t Au across 2.0m.  The new �Highway Zone� is located at depth of approximately 110 metres under the Trans-Canada Highway, immediately south of the mine.  The Magnet Mine is serviced with a shaft and winze to 2,640 feet and equipped with a headframe, production hoist, compressors, generator, hydro substation, and other equipment and facilities.  The Magnet had historical production during the period from 1938-1951 of 152,000 ounces of gold from 360,000 tons of ore at an average grade of 14.40 g/t Au.

Under the terms of the agreement signed with Roxmark in September 2007, Premier has the option to earn a 51% interest in the properties over a four-year period by making cash payments, issuing shares of Premier to Roxmark and carrying out, as operator, $7 million in expenditures to advance the highly prospective high-grade gold properties to a production decision.  Premier has the option to increase its interest in the Geraldton project to 70% by making further cash payments, issuing additional common shares of Premier to Roxmark and bringing the property to a production decision, following which Roxmark will be carried as to 30%.  The project area covers approximately 10 km of some of the most strategic ground in the region and is host to three past producing mines and several exploration targets. 

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 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 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.
