Lithium-rich
Case Pegmatite

The Case pegmatite, considered to be the fifth largest spodumene bearing pegmatite in the Superior Geologic province of Ontario.

The Case pegmatite a lithium-tantalum rich pegmatite is favorably located in northeastern Ontario, 75-kilometers east of the town of Cochrane in Steele Township. The property consists of five, road accessible claims, totaling 580-hectares. Mantis acquired the property for its lithium content, identified by the Ontario Geological Survey in Open File Report 6195 as being the fifth largest spodumene (mineral of lithium) bearing pegmatite in the Superior Geologic province.

The Case pegmatite has been investigated in the past for its rare element content, and although it has never been tested for its lithium content, the occurrence consisting of three dikes is known to host two zoned spodumene bearing dikes; the North dike measures 10-meters in width by >100-meters in length and the Central Dike, measures 39-meters in width by >350-meters in length. Within these dikes, the spodumene bearing zones in the Central dike average 21.6-meters in width, while in the North dike the spdumene bearing zones averages 5.0-meters in thickness. The dikes are open along strike and depth. Within these dikes the

lithium content ranged from 0.33% to 2.96% averaging 1.22% (expressed as LiO2).

“From a conceptual perspective, based on the historical data, the Case pegmatite has a high potential to host a significant lithium mineral component exceeding 2 million tons and averaging 1.2% Li2O*. As the electrification of the automobile gears up, and battery technology adopts the lithium ion cell, the demand for lithium is expected to increase. Mantis is in a very strategic position to take advantage of this demand with the acquisition of the Case pegmatite. The size and richness of the pegmatite coupled with its proximity to established infrastructure bodes very favorably for developing this resource.” (R. Ross CEO, PR October 5th, 2009).

Cautionary Note: Tonnage and grades are conceptual in nature and do not imply or indicate a resource as defined by National Instrument 43-101. There has been insufficient exploration to define a mineral resource and it is uncertain if further exploration will result in the delineation of a mineral resource.

Mantis future plans for this property include sampling, mapping and diamond drilling.
