Summary

The surrounding area of Nuinsco Resources Carbonatite complex has high potential for economical rare earth deposits. Given the current market conditions for rare earth metals and the urgency to find alternative sources. The Prairie Lake property is adjacent to the Prairie Lake Carbonatite Complex (PLCC). The PLCC lies at the intersection of fractures subsidiary to the northern extension of the Big Bay-Ashburton Fault (BBAF). The BBAF is deep seated, related to the Lake Superior mid continental fault, and is considered to be a controlling structure in the formation of the major alkaline intrusives at Prairie and Killala Lakes.

Geology

Regional Geologic Setting:

The Prairie Lake ring complex is an intrusive plug emplacing continental shield Archean felsic igneous and metamorphic rocks. The complex is spatially and age related ( see Gittens et al. f 1967) to the 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-aptites, 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.

History

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.

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.
