Rocher Deboule Acquires Several Manganese Properties

VANCOUVER, BRITISH COLUMBIA--(Marketwire - July 17, 2007) - Rocher Deboule Minerals Corp. (NEX:RD.H)(PINK SHEETS:RDBHF) has recently acquired BC mineral tenures based on their potential for economic deposits of manganese. Management is pleased to announce the acquisition by location of 100% interest in three manganese-bearing mineral occurrences located in Alberni & Clinton Mining Divisions of British Columbia, Canada. Descriptions of the manganese mineral properties are listed in the following table:

BLACK PRINCE: Open cuts and pits are exposed over an area measuring about 100 by 30 meters (at an elevation of 1,900 ft or 579 m), are located about 35 kilometers southeast of Port Alberni, BC near the headwaters of Shaw Creek. Three meter wide samples assayed from 22.2 to 40.8 per cent manganese and 30 to 57 per cent silica (Minister of Mines, Annual Report, 1918). Zones of massive, semi-massive and fracture coating pyrolusite are associated with black cherty rock and jasper beds (Paleozoic Sicker Group) that occur in an area of complex folding and faulting. Two rock chip samples taken at the Black Prince by Andris Kikauka, P.Geo., were sent to Pioneer Labs, Richmond, BC for whole rock geochemical analysis. Results are summarized in the following table:

JUNCTION CREEK: The occurrence of pyrolusite is located 3 kilometers southwest of Clinton, BC, and is about 0.8 kilometers east of the CN rail track (elevation 3,378 ft or 1,030 m). Syngenetic, stratabound mineralization covers an exposed area of about 100 X 15 meters and is hosted in chert and a bright red shale and minor green shale. The chert is intensely fractured and impregnated with black manganese oxides. A rock chip sample from this occurrence assayed 33.4 per cent manganese (Source: MINFILE, 092P 138).

OLSON: Veins and stringers of pyrolusite are found on a north trending ridge located 5.6 kilometers southwest of Clinton, BC (elevation 3,526 ft or 1,075 m). Syngenetic, stratabound mineralization covers an exposed area of about 500 X 75 meters and is hosted in massive limestone and limestone breccia of Permian-Triassic Marble Canyon Formation, with minor chert. A rock chip sample taken across a width of 3.1 meters assayed 15.8 per cent manganese (Source: MINFILE, 092P 151).

The company plans to carry out a program of systematic geochemical sampling and geological mapping and magnetometer geophysics to outline targets for future exploration and development work.

The above acquisitions compliment the Company's recent acquisition of a large portion of the Artillery Peak, Arizona, manganese camp where a historical resource of 175 million tons grading 3.5 - 4% Mn were reported in Information Circular #7843 (Manganese Deposits of Western Arizona) dated 1958. See NI 43-101 Manganese Mineral Resource Evaluation at www.sedar.com.

Where historical estimates are referred to, the Company has no classification of the resource or reserve, and the Company has not obtained enough of the original data and has not done the work necessary to verify the classification of a resource or reserve. The Company is not treating the estimates as a NI 43-101 defined resource or reserve verified by a qualified person, and the historical estimates should not be relied upon.

Rocher DeBoule is a company focusing on exploration and development of manganese and iron oxide, copper, gold (IOCG) potential projects located in North America.
