Drilling begins on Rare Earth/Carbonatite Niobium Property
Added October 21st, 2009 – Vancouver, British Columbia
Mr. Larry W. Reaugh, President & Chief Executive Officer of Rocher Deboule Minerals Corp. (TSX.V: RD; Pink Sheets: RDBHF) (“Rocher Deboule” or the “Company”) is pleased to announce the diamond drill has arrived on their 1,605 hectare (3.900 acre) rare earth niobium property located 7 km East of the community of Manson Creek in British Columbia. The focus of the drill program is to confirm surface values to depth and to identify the rare earth elements and strategic metals such as niobium, tantalum, titanium, lanthanum, neodymium, yttrium and gallium.
Geology consists of a syenite-carbonatite complex of Upper Devonian to Lower Mississippian age which occurs in metasediments of the Proterozoic Ingenika Group. The metasediments consists of quartz hornblende gneiss, quartzite, sericitic schlst, feldspathic wacke and garnet-biotite-muscovite schlst. These rocks are metamorphosed to amphibolite phases and impose a penetrative fabric on the complex, concordant with that of the country rocks. The carbonatite appears fault bounded and may be within a mylonitized zone related to regional tectonism. The country rocks are variable fenitized for tens of meters around the complex.
The Virgil carbonatite consists of syenite and biotite sovite which is composed of calcite, biotite and minor feldspar, apatite, zircon, columbite and pyrochlore. The zone which strikes 135 degrees and dips 50 degrees is 120 meters long and up to 40 meters wide. Sampling along the length assayed 0.19 per cent Nb2O5 and 0.18 percent zirconium (assessment Report 10729). A chip sample along 56 meters assayed 0.15 per cent TiO2, 0.05 per cent lanthanum and 0.03 percent neodymium (Geology, Exploration and Mining British Columbia 1974). Pg 278-279.
The Lonnie carbonatite is located on strike 4 km southwest of the Virgil.
The Lonnie carbonatite zone has been traced by surface trenching for a length of approximately 650 meters with widths up to 50 meters grading 0.20% Nb2O5. It strikes 120 degrees and dips approximately 60 degrees southwest. A zone in the centre of the property averages 0.3 per cent niobium (Nb2O5) across a width of 7.6 meters and a length of 240 meters (Open File 1987-17).
Diamond drilling will be located on the Lonnie carbonatite; results will be reported once they are received.
Sometimes called the “space age metal”
The two most useful properties of the metal are corrosion resistance and the highest strength-to-weight ration of any metal.
Titanium cal be alloyed with iron, aluminium, vanadium, molybdenum, among other elements, to produce strong lightweight alloys for aerospace (jet engines, missiles, and spacecraft), military, industrial process (chemicals and petro-chemicals, desalination plants, pulp and paper), automotive, agri-food, medical prostheses, orthopedic implants, dental and endodontic instruments and files, dental implants, sporting goods, jewelry, mobile phones, and other applications.
Annual production: 90,000 tonnes of the metal and 4.3 million tonnes of titanium dioxide. Price: $9.00/lb.
Lanthanum (La) is a soft, malleable, ductile silver-white metal. At this time all production of lanthanum comes from China. The fastest growing use for lanthanum is in nickel-metal hydride (NiMH) batteries. Toyota consumes 26 lbs of lanthanum for every NiMH battery in their Prius Hybrid. Toyota’s production of the prius in 2007 was 250,000 cars. Price: $6.10/lb. Annual Production: 31,000 tonnes.
Neodymium is a key component of an alloy used to make high power lightweight magnets for electric motors of hybrid cars, and in generators for wind turbines. Total production: 7,000 tonnes/year (China). Price: $9.00/lb. Annual Production: 25,000 tonnes.
The average price of niobium is currently $21.00 US/lb.
Niobium, a soft shiny, white metal, is also known as columbium since it was originally discovered in a mineral named columbite. Like tantalum, niobium, resists corrosion and maintains good physical properties at high temperatures but offers other outstanding attributes.
Although frequently found in the same minerals as tantalum, niobium is more plentiful in nature. Over 60 million pounds of niobium products are produced each year. The largest market for niobium (85%) is in high-strength, low-alloy steel production where it brings high temperature strength and corrosion resistance to gas pipelines, automobile components and structural steel.
