Canada Fluorspar, a specialty mineral resource company, declared that it has made a significant progress on its trenching program, which is being conducted along the Director Vein’s southern extension. High grade fluorspar mineralization has been demonstrated by current assays.
Assay results have been obtained for samples taken from Trench #4 and #5 along the trace of the Director Vein structure, which is sub-vertical and extends towards north-northwest direction. The trenches #4 and #5 are spaced 100 m apart and located 100 m and 200 m south of Trench #3, respectively. Mining at the two sites revealed considerable fluorspar mineralization in Trench #4 and expanded the Director Vein structure to 750 m along strike.
Trench #4 contains 33.3% CaF2 over 3.1 m of gouge and 81.3% CaF2 over 2.9 m of CaF2; the collective grade over 6.0 m is 56.49% CaF2. Trench #5 includes fault gouge with a grade of 2.66% CaF2 over a thickness of 7.2 m. Through the trenching program, the company has discovered the southern extension of the Director Vein structure in a region, which remained untested till date. Diamond drilling is needed to assess the resource potential of the structure. Assays from these and other trenches taken during the 2012 trench sampling campaign are conducted at SGS Minerals laboratory in Lakefield, Ontario. Ion Selective Electrode method and Dual Calcium method are used to evaluate the fluorspar content in low-grade and high-grade samples, respectively. SGS handles the internal check assay work, while staff at Canada Fluorspar review and confirm the assay results.
Material results of the Director Vein reconnaissance campaign, including preliminary exploration data on these trenches, have been already announced. Assay results from samples taken from the mineralized structure are still pending.
