Mantis announces significant tantalum grades at its Case Pegmatite project
along with multi-element associations of lithium, beryllium, gallium and
rubidium.

TORONTO, Feb. 11 /CNW/ - Mantis Mineral Corp., ('Mantis'-CNSX 'MYN') has completed its review of previous drill and channel cut data regarding the multi-rare metal potential of the Case Pegmatite. The table below summarizes the significant multi-rare element associations.

The above grades are comparable to most rare-metal pegmatites with the exception of tantalum which exceeds grades currently being evaluated in Canada; including First Gold's Pivert-Rose property in northwestern Quebec, MDN Inc's Anita project in the Lac St. Jean region of Quebec, Canada Lithium's Quebec project in Lacorne township. Importantly, the tantalum grades equal those at the Tanco mine in Manitoba, and the Greenbushes mine in Australia.

Highlighting the Case pegmatite's exploration potential, the following features standout:

    
    -   The North dike was explored along a 120-meter strike length to a 35-
        meter vertical depth and is up to 10 meters wide.
    -   The Main dike was explored along a 300-meter strike length to a 70-
        meter vertical depth and is up to a 30 meters wide.
    -   The Case Pegmatite dikes remain open along strike and at depth and
        potentially are amenable to open pit mining.
    -   Commonly pegmatite dike complexes are stacked in sub-parallel
        arrangements; this aspect remains to be tested.
    -   Of the 303-samples for which Mantis currently has reviewed,
        representing 200-core and 103-channel samples, 7% of the Ta(2)O5
        values are (greater than or equal to) 400 ppm (gpt).
    

The Case pegmatite is now emerging as a multi-element rare metals project with significant exploration potential. The tantalum values observed are amongst the highest reported in Ontario and Quebec and make for a potential economic deposit when combined with other rare elements. The project is proximal to infrastructure, being located only 75-km east of Cochrane along a major road.

Results of re-sampling the recently retrieved 508 meters of drill core will be released as soon as available.

About Tantalum and other Rare Metals

Tantalum is a rare metal with numerous growing applications. This high performance metal's largest application (65%) is in the electronics capacitor industry in such products as cell phones, DVD players, personal computers, digital cameras, gaming platforms, LCD monitors, wireless devices, telephone switch boards, and computer networks. Other applications include PC memory chips, igniter chips for car air bags, super alloys for jet engines, turbines, space vehicles, nuclear reactors, power plants, carbides for cutting tools, drill bits, silicon wafers, ink jet printers, x-ray film etc. Demand has been steadily increasing over the last 20 years by some 7% annually.

Prices are quoted in terms of pounds of Ta(2)O5. Prices are in the range of $50 per pound.

Lithium's biggest application is in the new generation light-weight, high charge batteries used in computers, mobile electronic devices and power tools. A future use for lithium will be in electric vehicles as the automotive industry develops electrically powered and hybrid vehicles powered by lithium ion batteries. Another major use for lithium is in the ceramic and glass industries.

Lithium prices are difficult to establish as they are negotiated per contract basis. Spodumene concentrate (greater than)7.25% Li(2)O sells in the range of $650-$700 per tonne, while lithium carbonate expressed as Li(2)CO(3) sells in the range of $2.50-$3.00 per pound.

Gallium is primarily used (70%) in integrated circuits. Opto-electronic devices, including laser diodes, LED and solar cells, represented 30% of gallium demand. Analysts estimated that the Gallium market will generate revenues of $3.5 billion this year.

Prices remain in the $450-$500 per kilogram range.

Beryllium metal is used for lightweight structural components in the defense and aerospace industries. Beryllium is also used as an alloying agent in the production of beryllium copper used in electronics.

Beryllium metal prices are in the range of $1000/kg.

Rubidium's principal application is in specialty glasses and is used in fiber optic telecommunication systems, including photoemissive applications such as photoelectric cells, night-vision devices, medical imaging devices and several other uses.

Current price for rubidium is $11/gram.
