Rocher Deboule Minerals Corp.-Diamond Drilling Update: Highland Boy Copper-Silver-Gold Bearing Quartz-Sulphide-Iron Oxide Fissure Vein Complex/New Director

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Sept. 24, 2007) - Rocher Deboule Minerals Corp. (NEX:RD.H)(PINK SHEETS:RDBHF) -

Management is pleased to announce the completion of a total of 3,629 feet (1,106.1 m) of diamond drilling from 6 drill holes on the Highland Boy quartz-sulphide-iron oxide vein complex located 2 km east of the past producing Rocher Deboule Cu-Ag-Au mineral occurrence (8 km south of Hazelton, BC). The drill core is presently being logged, split in half and subject to 61 element ICP geochemical analysis.

The Highland Boy Cu-Ag-Au mineral occurrence features two 090 to 120 trending and steeply north dipping quartz-sulphide-iron oxide fissure veins that outcrop in rugged mountain terrain at 5,800-6,500 ft (1,768-1,980 m) elevation. The southernmost vein zone is traced west along surface to the No. 4 Rocher Deboule Vein. The Highland Boy veins contain massive and banded chalcopyrite, coarsely crystalline magnetite and pyritohedral pyrite crystals 1 inch (2.5 cm) in diameter, in a gangue of quartz, calcite, dolomite, hornblende, tourmaline, actinolite, sericite, biotite and chlorite.

Additional prospecting in the vicinity of the 2 main veins led to the discovery of several parallel and perpendicular quartz-sulphide zones where a total of 15 rock chip samples were taken across widths of 0.1-2.0 meters from a 200 X 300 meter area located in the cliff area west of the drill site. In addition to prospecting, a 300 meter long 120 degree trending baseline was surveyed and a total of 2,000 meter line-grid total field magnetometer surveying was carried out along 030 degree tie-lines. A GEM GSM 19T magnetometer was used to take readings at 12.5 meter spacing. A total of 6 soil samples were taken along the west extension of the Highland Boy at 50 meter spacing.

The Highland Boy upper and lower veins were the focus of exploration work by Rocher Deboule Minerals in 2007, in order to determine the correlation between the 2,000-3,000 nT total field magnetic anomaly and nearby mineral trends on the Highland Boy upper vein. Results from rock chip sampling the Highland Boy upper vein indicate there is relatively low arsenic-antimony values with elevated values of Cu-Ag-Au-Fe. The iron notably occurs as magnetite, and the magnetometer geophysical survey performed clearly shows a direct correlation between the Highland Boy upper vein and a 2,000-3,000 nT increase in total field, especially at the west end of the upper and lower vein. The magnetite zone as indicated by the magnetic survey (and verified by Dighem airborne survey carried out by Fugro Airborne Surveys Corp, July 2007) correlates closely with Cu-Ag-Au bearing sulphide fissure vein mineralization of the Highland Boy upper vein.
