Prairie C is pleased to announce  an outstanding result from a platinum group, gold and base metal assay on a grab sample associated with a  carbonate breccia zone in Archean mafic host rocks from it's Cobalt, Ontario project area.. Results are as follows:

Silver         0.11     oz/ton
Gold          0.60     oz/ton
Platinum    0.89    oz/ton
Palladim    1.20    oz/ton
Iridium      .60     oz/ton

Copper    .08%
Nickel        .10%
Cobalt    .08%
Mercury    .25%
Lead       .17%
Sulphur    .72%
Arsenic    .65%

Additional samples of this claim area have been sent to various labs for  verification and analyses. Previous results from our 2000 exploration season attained values of Pt  0.01 g/ton and Pa 0.02  g/ton and Au 0.03 g/ton in this area from a number of archean rock samples. This area has also demonstrated anomolous chrome values up to 732 ppm and copper exceeding 2700 ppm  as well as anomolous values in a broad range of minerals.

In addition to excellent sulphide potential within this significant property holding there appears to be excellent potential for diamonds based on the discovery of a number of heterolithic lamprophyres deemed similar to the Menses and Sandor types known to host significant diamond potential in Wawa, Ontario. A number of site visits by the Resident Geologist for the Cobalt Camp have resulted in sample results and a write up in this past seasons Report on Activities due in print soon. Samples have also been sent to Kennecott for analysis. Geology and structures are consistant with previous discoveries made within the Lake Temiskaming Structural Zone. The potential is very high for these claims. The following is an excerpt from our assessment work report for the 2000 season currently on file with the Ministry of Northern Development and Mines

Regional and Structural Geology (Lovell and DeGijs, 1976, Open File Report)
The Cobalt Camp and claim area lay within the Cobalt Embayment, a significant geological structure referred to as an inferred basin, is known to host significant base and precious metal deposits throughout . This  project area is along the margin between the southern and superior structural provinces of the Canadian Shield.

There are 3 main regional fault structures trending northwest within the area. They are the Montreal River, Lake Temiskaming and Cross Lake faults. Numerous secondary and subsidiary faulting is noted throughout the area. The extensive tectonic activity locally is considered chiefly responsible for  regional and local metamorphism in association with successive intrusion events.

The basement rock consists mainly of early precambrian metavolcanics and metasediments such as massive andesitic and basaltic lavas, pllow lavas, pyroclastic and erosional sediments and diabase intrusives. Intrusives of granite, syenite and lamprophyre are noted as dikes and  dike swarms.

The Archean age basement is unconformably overlain by huronian supergroup sediments and clastic rocks. The predominant rock of this type is the Cobalt Group featuring mostly Lower Coleman Member and Lorrain Formation.These rocks are all intruded by Nippissing Age diabase dykes and sills and by the Algoman granite batholith in Lorrain Twp.

The relatively flat lying sill has produced a large basin like structure that has rafted up a portion of the basement rock in the central portion of the map area(Lovell and DeGrijs,1976) and has also rafted and separated a large area of syenite believed to be connected at one time. All rock types are exposed at surface as are sections of the  relevant contacts throughout the area.

Overburden is varying in thickness and consists of thick sand and glacial till on flat and low lying areas and filling the valleys between outcrops.

Claim Group Geology

These claims consist of  both sides of the generally east/west contact between the Lorrain granite batholith lying in the north half of the claims and the archean age mafic to felsic metavolcanic and volcanic rocks in the southern half. This contact runs east in the south half of Lotís 3, 4, 5 and 6. In Lot 6 the Algoman granite contact continues eastward and the keewatin rocks contact with the syenite. Beyond Lot 6 Concession 3 to the east,  is predominantly Syenite in the south half of the concessions in contact with the LorrainBatholith which occupies the north portion of the concessions.The granite and keewatin also contact the diabase sill in the south part of Lot 3, Con 3.

Located in Concession 3 of Lorrain Twp, this claim group was initially being evaluated for precious and base metal potential associated with the keewatin rocks. Prospecting and sampling began  with  an examination of an outcrop of gossan reported by Lovell and DeGrijs in Miscellaneous Paper 51, OGS.

Additionally, a recent Airborne Magnetic survey conducted by the Ontario Geological Survey(Treasure Hunt) revealed a number of  magnetic highs in this claim area  Multi Element and Whole Rock analysis was performed on 22 grab/chip samples to determine base metal potential and basic geochemistry. Gold, platinum and palladium assays were also performed with results up to:.

Au .03 g/t, Pt .01 g/t, Pa .02 g/t,  Ag 3.6 ppm,  Co 44 ppm,  Cu 2742 ppm, Cr 732 ppm, Ni 215 ppm, V 222 ppm,

Closer examination of this area revealed a number of lamprophyre dykes associated with Keewatin interflow sediments and volcanics in proximity to the Algoman granite contact. These dykes appear similar to those which have produced positive results for diamonds in the Wawa, Ontario area.  This area  surrounds a northeast trending fault which runs perpendicular to the nothwest trending, Cross Lake fault. The Cross Lake Fault is a large regional structure known locally to host diamondiferous kimberlites near associated perpendicular fault structures.  Recent visits to the site have yet to be reported on by the Resident Geologist for the Cobalt area.  A program of limited mechanical stripping has revealed a significant number of lamprophyre dikes within an area  in claims 1225264 and 1225265 which may represent a portion of a much larger target area. A detailed examination of this site was carried out with a view to developing itís entire potential through further stripping work and a  more detailed sampling and geological mapping program is proposed to be conducted by a geologist next season.
