Mantis Reports on Results of its Diamond Drill Program Conducted at the Rottenstone Projectadmin
Mantis Mineral Corp. announce the results of the diamond drill program conducted at its Rottenstone Nickel-Copper-Platinum Group Elements project, located in northern Saskatchewan. Seven holes totaling 1,177-meters of drilling were completed.
This very limited drill program focused on seven VTEM (Versatile Time Domain Electromagnetic) targets selected from the data base of over 200-conductors. The airborne survey which covered 1,171-km(2) was flown by Geotech Ltd. in the early summer of 2008.
The results of the drill program confirmed the presence of conductive sulphides in four of the targets. The sulphides encountered in these holes are considered to be formational representing sulphide-rich sediments.
The presence of these sediments bodes well for the area, as they can provide the sulphide source by which a magmatic body attains sulphide saturation dumping base and precious metals.
The three holes that did not encounter their conductive targets were drilled for practical reasons just beyond the envelope of the ultramafic body that hosts the mineralization of the Rottenstone deposit. Despite not having intersected significant mineralization, narrow sections of rock possibly linked and stemming from the host ultramafic were intersected.
The company considers that in the context of the expansive area of the favourable geological environment encompassed by the Rottenstone Project, the program achieved a technical success, and added hard data upon which to base future exploration programs.
An exploration program designed to filter conductors warranting follow-up drilling coupled with a larger more extensive drill program would greatly enhance the chances of discovering either new prospects or the extension-feeder to the main deposit. Mantis is confident that such a program is necessary to properly assess this sizeable target land base.
The Rottenstone deposit which originally had a delineated reserve reported at 50,000-60,000 tons grading 2% nickel, 2% copper, 0.22 opt platinum and 0.15 opt palladium was mined between 1965 to 1968. Approximately, 28,724 tons of ore was extracted during this period. The mined ore produced a 5,564 ton concentrate that graded 10.36% Ni, 5.74% Cu, 0.10 opt Au, 0.53 opt Ag, 0.33 opt Pt and 0.53 opt Pd. In this respect, the Rottenstone deposit is very unique. The contained precious metals of the Rottenstone ore, exceeds many of the ores from world class PGE deposits.
Dr. Larry Hulbert former geologist with the Geological Survey of Canada, an acknowledged expert on magmatic nickel-copper-platinum group elements deposits and very familiar with the geology of the Rottenstone area is the expert consultant for the project.
