For Immediate Release: May 17, 2000
Prairie C is pleased to announce commencement of 16km’s of grid cutting in preparation for a Ground Geophysics survey, geochemical sampling and mapping to develop numerous surface showings on it’s Santa Maria Property located in Gillies Limit Township. Located in the south of the famed Cobalt Mining Camp these claims are available for option and comprise 170 units or 6800 acres of contiguous mining claims in Gillies Limit and Lorrain Twp.
The Santa Maria Property
The Santa Maria property is reported as the location of the discovery of a 2005 pound silver nugget float which resided outside of the Toronto Museum for many years The property is located within the Cobalt Mining Camp which is world renowned for it’s celebrated production of silver and cobalt ores during it’s prolific, 80 year history. The property has seen only limited exploration and development as a result of the traditional practice of focusing on low tonnage high grade ore deposits close to surface and poor market conditions resulting in limited investment capital availability.
It is apparent from the compilation of available information and the physical examination of the property that it exhibits all the necessary geological features considered typical to host silver and cobalt orebodies. These favourable structures are noted at most if not all of the significant past producers in the camp and will be the focus of our first project this year. Base metal and Platinum Group mineral potential will also be evaluated.
These features are:
The presence of a contact between Nipissing Age Diabase intrusive into Keewatin age metavolcanics and volcanics. This contact is considered to be genetically related to the deposition of the ore in this area. The undulating nature of the diabase intrusive creates basinal depressions in the underlying structure. The property overlies a portion of such a basin. The diabase intrusion underlies the west half of the property from a depth of 0 feet in the west and about 550 feet toward the center at a dip of 20 - 30 degrees. Keewatin rocks form the hanging wall of this intrusive.
Relative proximity to large controlling fault structures such as the Montreal River, The Cross Lake and Lake Temiskaming Faults. These regional structures in association with localized fault structures in concert with the diabase intrusion are reported to be key conditions for local mineral deposition. The Santa Maria property exhibits all of these conditions. The Cobalt and Silver Center Mining Camps both lie between these regional structures.
Economic Geology - Historical Summary
There is strong evidence of subsidiary faulting around and throughout the claims and significant reports of veining and mineralization found near the diabase contact in the south half of the claims. Reported are the following:
A 1300 foot long quartz vein from 2-4 feet wide. Cobalt mineralization reported in a 3 foot wide section trending N55degW at the southern end of it in diabase. Native silver, cobalt and gold are reported in pitting and trenching along the northwest trend of this vein. Additional discoveries of mineralized quartz and carbonate veining are encouraging.
A zone of strong sulphide mineralization striking N33degW containing an 8 inch wide quartz vein at one point. 200 feet to the west a similar 8 inch mineralized quartz vein is located. 800 feet northwest is another north trending 8 inch vein. Numerous other smaller veins are reported to contain mineralization as well.
An adit was driven on a vertical, 7 inch wide calcite vein reported to carry considerable cobalt. It was driven 172 feet. Report of silver nuggets encountered. Strike is N35degE.
Additional contacts between the diabase intrusive and the various sediments of the area and the presence of the contact between the keewatin rock and the intrusive Lorrain Granite Batholith in the east provide additional potential to host silver cobalt deposits in the keewatin rocks. Deposits hosted in Huronian and Keewatin sediments are also commonly known in the camp.
The presence of an 80 foot wide mineralized inlier of chert in the keewatin rocks 800m north of the grid area is convincing evidence of base metal potential as these bodies are known locally to host base metals and gold to varying degrees.These bodies are also well known to underlie some of the most productive silver orebodies in the camp. Reported evidence of proximal vent facies rock and observed hydrothermal alteration with minor mineralization within the grid area further support an investigation of this potential.
Adjacent to the Santa Maria property, on approximately 11,000 acres of contiguous ground optioned from Prairie C, Cabo Mining Corp. of Vancouver is continuing exploration for Volcanogenic Massive Sulphides and base metal mineralization. They have cited similarities between the mineralogy and structure of the Cobalt Area and the Timmins Kidd Creek area; as important features guiding their exploration. Both areas lie within the Cobalt Embayment which is a geological structure, well known to host VMS type deposits. Their focus is on the local volcanic and interflow sediments similar to the polymetallic host rocks of Sturgeon and those of the Noranda Texas Gulf type found at Kidd Creek in Timmins.
