MNTCF rare elements

[killerB]

MNTCF-Mantis reports 2878 g/t rubidium over 9-meter width from its Case pegmatite, lithium-rare-element project.

TORONTO, Jan. 27, 2010 (Canada NewsWire via COMTEX) -- Mantis Mineral Corp., ('Mantis'-CNSX 'MYN') is pleased to announce that as a result of its on-going compilation of data from its Case pegmatite lithium project in Ontario, significant rare element minerals including rubidium (Rb) values have been noted in assay results.
During 2001, Plantinova Resources, conducted a program of surface channel cut sampling and drilling, testing three sub-parallel closely spaced pegmatite bodies. Drill core from seven drill holes totaling 508 meters and six channel cuts representing 113-meters of cutting from which 116-samples were analyzed for multi-element associations. Mantis is reporting at present only the rubidium findings from lab certified assay results included in the geological assessment report filed with the Geoscience Assessment Branch of the Ministry of Northern Development Mines and Forestry, Ontario.

The six, saw-cut channels were cut across the North, Main and South dikes, two across the 'North' dike, three across the 'Main' dike and one across the 'South' dike. Available results are summarized below.



<<
------------------------------------------------------------
Dike Channel Cut Width-meters Rubidium g/t
------------------------------------------------------------
North SC-1 4.0 1148
------------------------------------------------------------
North SC-2 4.0 2053
------------------------------------------------------------
Main SC-3 9.0 2878
------------------------------------------------------------
South SC-6 12.0 1698
------------------------------------------------------------
Note: no assays available for SC-4 and 5, from the Main dike.
Assay interval - grade is composite calculated weighted average.

These results are very significant. The saw cuts, 3-4cm deep were cut perpendicular to the strike, on glaciated flat outcrop resulting in high quality sample retrieval. Individual sample lengths were generally 1-meter long.
All of the dikes strike northeast-southwest. The 'North' dike is 12-meters wide and has been traced for 100-meters. It is open to the southwest. The 'Main' dike is 39-meters wide and has been traced for 350-meters and open in both strike directions. The 'South' dike is 10-meters wide and is also open in both strike directions.

Of the seven holes drilled into the pegmatite bodies, the rubidium results are presently available for only drill hole number-2. It was collared to undercut the northeast end of the 'North' dike where the dike appears to narrow. The rubidium values from this hole are as follows:



<<

------------------------------------------------------------
From-meters To-meters Length-meters Rubidium g/t
------------------------------------------------------------
36.7 44.0 7.3 914
------------------------------------------------------------
49.0 54.0 5.0 915
------------------------------------------------------------
61.0 66.0 5.0 1151
------------------------------------------------------------
Note: assay interval - grade is composite calculated weighted
average.

These results from the Case Pegmatite compare very favorably with the results recently released by First Gold Exploration Inc, in which they reported in a press release dated Jan 25th, 2010 a drill intercept of 2,922 g/t rubidium over 6.7-meters. Additional assay data will be released shortly.
Commented Robin Ross CEO: "This is thrilling and a major discovery given that the price of some of these rare elements like rubidium are quite high. The addition of the rubidium and rare element minerals, coupled with the project's lithium potential to host 2,000,000 tons of spodumene (lithium mineral) bearing material grading 1.22% Li(2)O(3), is positioning the Case Pegmatite to become another very significant asset for Mantis and its shareholders. In addition, the Case Pegmatite is very accessible, only 75-kilometers east of Cochrane".

As the potential of the Case Pegmatite evolves, through continued compilation work, Mantis is planning a summer exploration program of mapping, geophysics and drilling.

Rubidium

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 $1118 U.S for 100 grams.

This news release has been viewed and approved by Walter Hanych, Senior Geologist and Project Manager, who is a Qualified Person as defined by National Instrument 43-101 and is responsible for program design and quality control of exploration undertaken by the Company. While these assays do not conform to National Instrument 43-101 they are generally considered reliable according to local industry standards.
