CFI Announces Assay Results From Diamond-Drill Holes Completed on the Director Vein08:46 EDT Wednesday, May 08, 2013
ST. JOHN'S, NEWFOUNDLAND--(Marketwired - May 8, 2013) - Canada Fluorspar Inc. (TSX VENTURE:CFI) ("CFI" or the "Company") is pleased to announce the third set of assay results from three holes on its Phase 1 and Phase 2 diamond drilling program along the northern section of the Director Vein beneath the Aluminium Company of Canada's (Alcan) old mine workings and southern extension of the Director Vein. The assay results from the previous five drill holes of the Company's Phase 1 and Phase 2 diamond drilling program were disclosed by press releases on March 12, 2013 and April 24, 2013.
One of the three drill holes, DS-13-105, is located 974 metres south of the old Alcan shaft. This drill hole was collared with an azimuth of 053.4° (GN) and an inclination of -60°, and intersected the Director Vein structure returning an average assay value of 15.7% CaF2 over 5.00 metres with 1.14 metres of lost core for a total of 6.84 metres. Drill holes DS-13-115 and DS-13-116 are both located approximately 1,600 metres south of the Alcan shaft and 626 metres south of drill hole DS-13-105. Both drill holes collared with azimuths of 053.4°(GN) and inclinations of -60°, intersected the Director Vein structure and returned assay values of 36.6% CaF2 over 5.72 metres in hole DS-13-115 and 59.9% CaF2 over 13.00 metres with 1.40 metres of lost core for a total 14.40 metres in hole DS-13-116.
Lindsay E. Gorrill, CEO of Canada Fluorspar Inc., stated, "The assays from the first two holes on the south extension at shallow depths are very encouraging. This is the area where we saw high assays results from trenching done in 2012. DS-13-116 showing almost 60% grade with 13 metres width is a significant intersection and validates the trenching done in 2012."
The fluorite mineralization in the north-south trending veins at the St. Lawrence Project and the Company's 100% owned mineral license occur in the form of massive mineralization and as fault gouge. Historically, core drilling of the massive mineralization has resulted in good core recovery. The areas of faulted mineralization generally contain finely ground fluorite and larger fragments of the harder siliceous material. Drilling through the faulted gouge zones commonly results in poor core recovery as the fine grained fluorite material in the vein is washed out by the drill fluid. Both drill holes DS-13-105 and DS-13-116 successfully intersected the Director Vein structure, however, due to the fine nature of some of the vein material, core recoveries in the structure ranged from 83-84% and 90-91% in DS-13-105 and DS-13-116, respectively. Past underground mine operations document the high grade, fine, sandy fluorite mineralization in the vein structure.

CFI has received assay results for samples collected from drill holes DS-13-105, DS-13-115 and DS-13-116 located along the southern extension of the Director Vein. Drill hole DS-13-105 was drilled from west to east and 146 metres south of a previous drill hole, DS-13-104, which was reported in a press release dated April 24, 2013. Drill holes DS-13-115 and DS-13-116 are located on the same plane and 772 metres south of drill hole DS-13-104 and 626 metres south of DS-13-105. All three drill holes were drilled from west to east intersecting the Director Vein structure, which trends north-northwest and dips steeply from east to west. Drill hole DS-13-105 intersected the Director Vein at 262 metres (225 metres vertically from surface) and 120 metres below the nearest old Alcan workings (120m Level). The vein structure was weakly mineralized as demonstrated in the table below. The drill hole is believed to have intersected a pinched zone. Drill holes DS-13-115 and DS-13-116, located underneath Trench No. 3 which was reported in an earlier press release on April 16, 2012 to contain massive fluorspar mineralization with a fluorspar vein measuring 9.4 metres wide and grading 90.7% CaF2, intersected the Director Vein approximately 65 metres and 39 metres, respectively, down the hole (70 metres and 40 metres, respectively, below surface). Drill hole DS-13-116, the shallower of the two holes, intersected a strongly mineralized structure as demonstrated by the 13.00 metre long intersection carrying a grade of 59.9% CaF2. Drill hole DS-13-115, the deepest of the two holes, intersected fluorite mineralization similar to DS-13-116 above but with a decrease in width and grade as demonstrated in the table below. The Director Vein structure appears to be narrowing and reducing in grade as it gets deeper.
The following table details the results of the third set of drill holes completed by CFI on the Director Vein to the north below the old Alcan workings and two drill holes on the south extension of the Director Vein.

Assays on these drill holes were carried out at SGS Lakefield Laboratories ("SGS") of Lakefield, Ontario, using the Ion Selective Electrode method to determine the fluorite content in the low-grade samples and the Dual Calcium method for samples expected to contain high-grade values (i.e., those with significant visible fluorspar in the drill core).
Quality Assurance and Quality Control ("QA/QC")
Check assay work by CFI includes insertion of duplicate samples and blanks with regular batches of mineralized samples of drill core. QA/QC work is also done at SGS, and results are reviewed and verified by CFI personnel. An independent geological consultant (Qualified Person) has submitted additional samples collected from the drill core for analyses.
Phase 1 of the current exploration program is designed to assess the northern extension of the Director Vein structure. The six drill holes with assay results to date have shown that the fluorspar mineralization at the Director Vein extends further along strike and at depth from the old Alcan workings.
Phase 2 of the 2013 exploration program has been designed to evaluate the southern extension of the Director Vein. A trenching program and a geophysical survey conducted in the area during 2012 identified the structure over a strike length of 1000 meters. The current drill program was planned to evaluate the mineral potential, at depth, of the southern extension of Director Structure and to test the north extension of the adjacent Hares Ears Vein to the west.
Historic mining operations by Alcan on the property produced in excess of 4.2 million tonnes of fluorspar during a 44 year continuous production from 1942 to 1977. Production resumed in 1986 and continued until 1991, when St. Lawrence Fluorspar Limited reopened the nearby Blue Beach North Mine and processed 440,000 tonnes of fluorspar ore from small open pits, one of which was located in a surface pillar at the Director Mine near the main shaft.
Initial exploration information regarding the 2013 exploration program at Director Vein was included in the Company's press releases dated January 16, 2013 and March 12, 2013.
To date, six (6) Phase 1 drill holes have been completed together with 20 additional drill holes in Phase 2 (south extension of the Director Vein) of the 2013 exploration program. Assay results for 18 of the drill holes in Phase 2 are pending.
Historic exploration data indicates that there are more than forty mineralized veins within the CFI property. The three prominent vein structures, however, are the Director Vein, Blue Beach North Vein, and the Tarefare Vein. Probable Reserves of the Blue Beach North and Tarefare veins total approximately 5.4 million tonnes at an average grade of 39.8% CaF2. These Mineral Reserves have been outlined to a vertical depth of 300 metres below the surface, but fluorspar mineralization extends further at depth. The key assumptions, parameters and methods used to estimate the Mineral Resources and Mineral Reserves, as well as other relevant information, including data verification, with respect to the Blue Beach North and Tarefare veins can be found in a NI 43-101 Technical Report prepared by the Roscoe Postle Associates Inc. dated March 6, 2013, which has been filed by the Company on SEDAR (www.sedar.com).
