Nuinsco starts trenching at Prairie Lake

2010-06-01 11:52 ET - News Release

Mr. Paul Jones reports

NUINSCO LOOKS TO INCREASE 330-360 MILLION TONNE ETMI AT PRAIRIE LAKE

Nuinsco Resources Ltd. has begun a large-scale trenching program to totaling over two kilometres at its 100-per-cent-owned Prairie Lake project in northwestern Ontario. This program focuses on parts of the property that to date have seen little or no systematic exploration and are not included in the 330- to 360-million-tonne exploration target mineralization inventory estimate which was announced earlier this year.

"The ETMI released in January demonstrates the huge scale and potential economic significance of this multi commodity deposit. However, with only 12 per cent of the total surface area of the Prairie Lake complex included in the ETMI, we have barely scratched the surface," said Nuinsco's president, Paul Jones. "The ambitious trenching program will provide exposure in areas of the intrusive complex where no diamond drilling whatsoever has been conducted (the north and east). Results of systematic trench sampling will be used to develop additional work plans aimed at further evaluating the subsurface potential of the project."

Prairie Lake Carbonatite:

Heavy minerals associated with carbonatite were recovered from several samples. Of particular interest is sample 16-MA-99. This modern alluvium sample yielded a large number and variety of heavy minerals similar to those recovered from the Prairie Lake Cabonatite. In addition, several other heavy mineral types, also found at the Molycorp Pass Carbonatite in northern California, were recovered. The Molycorp Mountain Pass Carbonatite is of particular interest as it is a major supplier of rare earth metals to the world and has been since the early 1950s. Barite, synchysite and bastnaesitite are the 3 important minerals associated with the California deposit which measures only 200-300 feet across. To test whether the mineral signature of the modern alluvium sample were derived from the Prairie Lake Carbonatite, which occurs up ice, 2 bedrock samples were taken close to the sample site. The minerals derived from these bedrock samples confirmed that the modern alluvium mineral signatures were local and similar to that reported from the Molycorp Mountain Pass Carbonatite.

Introduction:

 
The Prairie Lake Carbonatite Complex is a quasi circular structure with an approximate surface area of 10 km2 . The complex has been ace dated by several investigators at l billion years. It intrudes Archean granitoid country rocks which show moderate to intense fenitization.
 
Rocks in the complex include sjrfvites, ijolite-urtites, nepheline syenite-malignites and a variety of lamprophyres. The ijolitic rocks actually grade into silicocarbonatite* in ir.uch of the complex. From petrographic investigation it is apparent that the silicate minerals and the carbonates were co-cryszaliizec as immiscible fractions from the same magma. Wollastonite is a secondary mineral replacing earlier silicates ir. the silicocarbonatite, ijolites and malignites. In sorr.e areas wollastonite is a major mineral. The occurrence of wollastonite in the complex is variable.
 
Although scrr.e investigators have attempted to describe the ceoiocy of the Prairie Lake Complex, the actual spatial relationship of rock types is not known. This is due in part to a scarcity of outcrops and partly because the complex has only received cursory attention from past investigators. Eccnomic minerals in the complex which are potential ore targets include pyrochlore-betafite, apatite and wollastonite.
 
General Geology:
 
Regional Geologic Setting
The Prairie Lake ring complex is an intrusive plug emplacing continental shield Archean felsic igneous and metamor phic rocks. The complex is spatially and age related ( see Gittens et al. f 1967) to the miaskitic nepheline syenite complexes of Coldwell to the southeast and Killala Lake to the northeast. It is reasonable to assume that these complexes represent differentiated segments of magma that have traveled in different paths bur that have been generated from the same magma source. The differentiation in such cases may be extensive such that the petrology of the complexes and economic geology can show strong dissimilarities.
 
The Prairie Lake complex can also be seen to fall within the North American Mid-Continent gravity high and the major regional Carb Structure which includes several carbonatite complexes and extends for a distance of at least 800 km (seeErdosh,1979).
 
Economic Minerals and Potential:
 
The Prairie Lake carbonatite complex shows excellent economic potential for several elements, most important of which are niobium and uranium. These elements both occur in minerals of the pyrochlore group which are found in the carbon-atites, silicocarbonatites and ijolites. The composition of the pyrochlores show local variations from uranium-rich uranium- pyrochlore and betafite to the uranium impoverished species, pyrochlore. For a classification of the pyrochlore system nomenclature the reader is referred to Hogarth (1977). The uranium content of the pyrochlores does not appear to be depend ant on the rock type. Of the pyrochlore group minerals (including the species pyrochlore, uranpyrochlore and betafite), betafite is most frequently encountered in the Prairie Lake rocks.
