Rare Earth Mineralized Carbonatite Intercepted in Carbo Diamond Drilling

Trading Symbol CIN-TSX.V

VANCOUVER, Sept. 13, 2011 /CNW/ - Canadian International Minerals Inc (CIN-TSX.V) is pleased to announce that mineralized carbonatite and related alkaline rocks in significant intercepts have been intersected in the 2011 Phase I diamond drilling program on the Carbo Rare Earth Element (REE) property.

This first phase has focused on Targets, A, C, and D as outlined in our news release dated April 21, 2011. Target A is approximately 2000 meters south-east of Spectrum Resources 2008/09 drilling: select drill hole intersections from that program included 48.64 meters of 3.55% combined Rare Earth Elements (REEs), 144 meters of 2.2% combined REEs and 72 meters of 2.92% REEs. (Graf, Lane, Morrison, 2009). All intersection reported by Spectrum were collared in mineralization and assays were given in total elemental REEs which understates REE oxide content.

The area currently being drilled is defined by distinct airborne magnetic and radiometric anomalies, coincident rare earth element (REE) and pathfinder soil geochemical anomalies, and newly mapped carbonatite surface exposures. Diamond drill core from the first eight holes has been examined cursorily, and the first  three holes have also been logged in detail. All of the holes have intersected intervals of mineralized carbonatite, associated alkaline rocks, and/or metasomatic alteration.

Carbonatite and related alkaline units can be up to several tens of metres in thickness. These units are generally planar, and parallel to the host rock (phyllite) fabric, which is consistently subvertical, and trending approximately 140 degrees on surface. Occasionally the carbonatite occurs as crosscutting dykes or veins. The carbonatite is typically a combination of calcite, dolomite, and/or ankerite with a variety of accessory minerals including rare earth minerals. Many of the alkaline dykes are commonly sulphide-rich, and occasionally host sodalite. The host rocks around the carbonatite are commonly altered to varying degrees. The alteration may include bleaching, hornfelsing, riebeckite, and flooding of feldspar-feldspathoids.

Through visual examination, observation under short wave filtered and unfiltered ultra violet lights, and Niton XRF analysis, several mineral phases have been identified. Significantly elevated REE concentrations have been confirmed in select carbonatite samples when analyzed with a Niton XRF. Light rare earth elements (La, Ce, Pr and Nd), Ti, Nb, and Zn have been found to be elevated in some samples, implying the presence of associated mineral assemblages. This is consistent with what was observed in the 2010 drill core. Light pink and peach-coloured REE-bearing minerals have been observed in hand sample from outcrop and in drill core, and generally occur disseminated in the carbonatite or as cumulates. Other minerals identified visually are fluorite, ilmenite, sphalerite, pyrrhotite, pyrochlore, chalcopyrite, magnetite, and sodalite. Several samples have been chosen for further analysis by the University of British Columbia's Mineralogical Research Group.

Core logging and property geological mapping at the Carbo is being led by Mallory Dalsin of Mackevoy Geosciences Ltd., who is in her second year on the project. Ms. Dalsin is completing a Master's thesis on the mineralogy, geochemistry and geochronology of the Wicheeda carbonatite complex at the University of British Columbia under the direction of Professor Lee Groat, a world renowned mineralogist. Ms. Dalsin is the recipient of a scholarship from Geoscience B.C. based on her study of the Carbo Project.

CIN has a multi-year drill permit for 30,000 meters, of which 5000 meters should be completed in the 2011 season ending late November. Core is being cut, logged, and stored at the company's expanded warehouse in Prince George, and samples are being sent to Activations Labs sample preparation facility in Stewart, B.C., with final analysis at their main laboratory in Ancaster, ON.

The Carbo property comprises 7 claims totalling 2,778.63 hectares in area, and is accessible by all weather gravel roads.  It is approximately 80 km north east of Prince George, BC, a major provincial regional centre for mining, construction and logging industries. The project is approximately 40 km east of B.C. Hydro`s major electrical corridor and within 45 km of CN Rail's northern B.C. trunk line with connections to all of North America and the major ports of Prince Rupert and Vancouver.

The company is also awaiting final assays from the extensive surface stripping and trenching at its Dead Horse Creek and Prairie Lake projects. Currently all of the project geologists associated with that data collection and interpretation have been seconded to the Carbo Project to expedite the core logging, sampling and data handling processed. Final results will be released when available.

Mr. David Turner, M.Sc., P.Geo., an independent Qualified Person (as such term is defined by NI 43-101) is responsible for the review of technical information in this release.
