Third Drill Added to Test Primary Geraldton Project Gold Targets:
More Surface Work, Drilling Scheduled for Northern Empire

Toronto, Ontario, May 29, 2008.  Roxmark Mines Limited (TSXV�RMK) today announced that Premier Gold Mines Limited (TSX�G), as operator, has added a third drill to accelerate exploration at the Geraldton Project in Northwestern Ontario.  To date, gold has been discovered in the first three targets tested as part of the ongoing program.  Drilling has now moved to test the primary two targets of the program, while one drill continues to expand on mineralization identified in the recently discovered zones.

Discoveries so far include two broad parallel (open pit style) horizons and high-grade veins located proximal to the historic Little Long Lac Gold Mine.  Results include 39.64g/t Au (1.16 oz/ton) across 2.0 metres contained within a wider zone of mineralization which returned 5.87g/t Au across 16.0 metres, and 42.97g/t Au (1.25 oz/ton) across 1.0 metre contained within a wider zone of mineralization which returned 2.01g/t Au across 101.0 metres.  Drilling has recently intersected significant visible gold in the western-most section drilled in the No.11 Vein Zone. 

Despite early successes, the two primary targets in the current Phase I program, the �Mine Repetition� and the Talmora Anticline Zone (�TAZ�), remain untested.  The Mine Repetition target represents the fault offset of the host horizon of the historic Little Long Lac Gold Mine from which more than 600,000 ounces of gold were produced during the period 1934-53 at an average recovered grade of 11.66g/t Au.  The TAZ target is a large untested fold structure similar to those that host the largest mines in the district.

Premier holds the option to acquire up to a 70% interest in the Geraldton Project from Roxmark by making cash and share payments to Roxmark, and performing exploration on the Project.  The current Phase I drilling is part of an ongoing minimum $2.5 Million exploration program aimed at confirming Premier�s belief that numerous untested prospective areas of the property could host additional gold mineralization.  A systematic drill program is being carried out at Little Long Lac in an effort to discover new zones and to establish gold resources in the Kailey, the No.9, No.10, and No.11 Vein zones. 

The Geraldton 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.  The Project area covers approximately 10 kilometres of some of the most prospective geology in the region and is host to three past-producing mines and numerous exploration targets in a district that has seen historic production of more than 4.1 million ounces of gold. 

Stephen McGibbon, P.Geo. is the Qualified Person for the information contained in this news release within the meaning of National Instrument 43-101. Core from Geraldton is sent to Accurassay Laboratories, an accredited mineral analysis laboratory in Thunder Bay, Ontario, for preparation and analysis utilizing both fire assay and screen metallic methods.

The Northern Empire Gold Mine
 
Northern Empire West Extension

Roxmark is currently preparing to resume a surface program on properties acquired late in the summer of 2007 that are along the strike of the Northern Empire gold mineralization.  The exploration program will consist of surface stripping, geological mapping and channel sampling.

Northern Empire Property

Roxmark has completed a surface drilling program aimed at expanding the gold mineralization of the Contact Zone.  Seventy-seven drill holes were drilled for a total of 8,385 metres.  The program was increased, to follow the mineralization, by 35% from the projected target of 6,200 metres.  Preliminary results were announced in a news release dated May 6, 2008.  Gold intersections were obtained from the Contact and Power Zones as well as the Iron Formation and Foot Wall Zones.  The drilling program is being supervised by Peter Bevan, P.Eng, a Qualified Person.  Additional results will be announced when available.  A complete assessment and the extent of the final results will be available in the near future.

A follow up to the exploratory drilling program is being planned for the summer of 2008 to expose surface gold mineralization.  Several areas of interest along a strike length of 1,250 have been outlined from drilling which require stripping and channel sampling.

The Northern Empire Mine was operated by Newmont Mines from 1934 to 1941 and was serviced by a shaft to a depth of 2,460 feet, producing 149,000 ounces of gold from 426,000 tons of ore at a recovered grade of 0.35 oz/t Au.  The onsite 200TPD mill (expandable to 500TPD) was built in 1982 and upgraded and permitted by Roxmark.

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 b oundary issues, since eliminated.
