Marathon Intersects 3.16 g/t PGM and Au and 0.40% Cu over 14 m
at Benton's Bamoos-Claw Lake-Four Dams Property


Thunder Bay , Ontario CANADA, April 30, 2008 /FSC/ - Benton Resources Corp. (BTC - TSX Venture, BNRJF - OTCBB_Pink_Sheets), ("Benton") and Marathon PGM Corporation ("Marathon"), are pleased to announce initial drilling results from the Bamoos-Claw Lake-Four Dams ("BCF") Property.  Benton's BCF Property adjoins Marathon's Copper and PGM Project near Marathon, Ontario and is currently being explored by Marathon under an option and joint venture agreement.  Numerous wide intercepts of PGM and Au and copper mineralization were discovered.  The results are very positive, as the limits of the Main Zone mineralization have been expanded with this initial phase of drilling.  

Highlights:
* drillhole MB-08-06 intersected 3.16 g/t PGM and Au and 0.40% Cu over 14 m (from 44-58 m)
* drillhole MB-08-06 intersected  2.02 g/t PGM and Au and 0.32% Cu over 18 m (from 7-25m)
* Main Zone extension on BCF Property to be included in Marathon feasibility study

Phillip Walford, President and CEO noted, "Drilling the north end of the Main Zone extension will bring this area up to the measured and indicated category.  The resource will be included in the feasibility study as part of the ore reserves and should extend the potential mine life."

Current Drilling
Drilling has provided valuable information regarding extent and features controlling mineralization.  
Hole MB-08-03 encountered a large inclusion of footwall volcanic rock, which had not been encountered in previous drilling.  MB-08-04 encountered only footwall volcanics, west of MB-08-05.  Holes MB-08-07 and MB-08-08 encountered mineralization to the east and west, respectively, of a footwall volcanic fragment.

Drilling on the BCF property is continuing and a second drill rig is being mobilized to further extend the high-grade W horizon on the Marathon property.

All of the samples were sent to Accurassay, an accredited laboratory in Thunder Bay, Ontario, to be assayed using fire assay and other standard techniques.
