Rocher Deboule Minerals Corp. (TSX.V: RD; Pink Sheets: RDBHF) reports that the Company has completed 17 HQ diamond drill holes for 9,930 feet (3,027 meters) on its Artillery Mountains Manganese property in Northwestern Arizona.

During the past year the market prices for manganese have more than tripled from US$0.68/pound since November 2005 to US$2.00/ pound currently (Ryans Notes).

Rocher has acquired, by staking, 180 lode claims for a total of 3600 acres (1,457 Hectares).  Manganese bearing sedimentary beds are known to exist over much of this area.  Geological mapping by the USGS and the US Bureau of Mines during the latter part of WWII and the early part of the cold war, when manganese was considered a strategic metal, has outlined numerous areas of interest. Rocher has staked most of these areas.  The drilling just completed has tested two of these areas and has found Manganese in both.

Preliminary research of past metallurgical testing on this property, done in the post war era, indicates that the manganese leaches readily in a vat leach process and as such a high quality electrolytic product can be produced.  The resource is situated in shallow dipping sedimentary beds where the terrain would allow open pit mining with a low stripping ratio.  Low mining and processing cost is believed to be an attainable target.  At this point in time the company is working on the premise that the rock with contained values of 1% manganese (20lb/ton) is of interest.

As such the following table of values lists the first set of assay results from mineralized sections intersected in the drilling with manganese values in excess of 1% Mn (20lb/ton).  The project has drilled 17 holes in all and the table lists the results from the first six holes.

Mapping and sampling are continuing on the property and metallurgical testing will begin as soon as suitable testing facilities have been identified and metallurgical samples have been prepared.
