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

The above grades are comparable to most rare-metal pegmatites with the exception of tantalum which exceeds grades currently being evaluated in
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
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
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
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
Prices remain in the
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
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.
