ST. JOHN'S, NEWFOUNDLAND--(Marketwired - Aug. 6, 2013) - Canada Fluorspar Inc. (TSX VENTURE:CFI) ("CFI" or the "Company") is pleased to announce the third set of assay results under the Company's Phase 3 diamond drilling program from three drill holes on its Grebes Nest property. One of the drill holes, GS-13-10, is in the same plane as previously reported drill holes GS-13-07 and GS-13-09 and had an average grade of 65.49% CaF2 over 8.52 metres, plus 0.60 metres of lost core. The other two drill holes, GS-13-14 and GS-13-15, are located 100 metres and 200 metres, respectively, east along strike from previously reported drill holes GS-13-07 and GS-13-09. The new vein structure is situated approximately 4 km from the former Tarefare Mine and less than 6 km from the former Blue Beach North Mine (see location map below). Both drill holes are located on the western end of the Grebes Nest grid area. Ground geophysical (magnetometer and EM) survey results indicate that the mineralized structure has potential to extend for more than 4,000 metres along strike.
Drill hole GS-13-10 was inclined at -45º and oriented at azimuth 214º. Drill hole GS-13-14 was inclined at -50º and oriented at azimuth 034º and drill hole GS-13-15 was inclined at -45º and oriented at azimuth 034º.

Drill hole GS-13-10 tested the down-dip extension of the Grebes Nest Vein on the same plane as the previously reported (press release dated July 11, 2013) drill holes GS-13-07 and GS-13-09. This hole intersected a vein structure having an average grade of 61.18% CaF2 over 9.12 metres, including 0.60 metres of lost core. Excluding the lost core, the vein has an average grade of 65.49% CaF2 over 8.52 metres.
Drill hole GS-13-14 intersected two vein structures: the first vein had an average grade of 41.62% CaF2 over 6.30 metres, with 1.35 metres of lost core. Excluding the lost core the average grade increases to 53.00% CaF2 over 4.95 metres. The second vein intersection had an average grade of 32.81% CaF2 over 9.34 metres.
Drill hole GS-13-15 intersected a vein structure with an average grade of 33.49% CaF2 over 2.98 metres.

"These latest drill results confirming a strike length for the West Grebes Nest vein of over 725 metres is extremely encouraging", stated Lindsay Gorrill, President & CEO of Canada Fluorspar Inc. "We remain confident that further drilling will extend the strike to 1.5 km as well as extend the vein down depth. Remaining drill holes are targeted to further interpret the vein along strike and down depth within the West Grebes Nest zone".
CFI has received assay results for samples collected from drill holes GS-13-10, GS-13-14 and GS-13-15 located along the western part of the Grebes Nest target area. Two of the drill holes, GS-13-10 and GS-13-14, are spaced approximately 200 metres apart and hole GS-13-15 is spaced 100 metres east from hole GS-13-14 and extends the previously reported strike length of 425 metres out to a strike length of approximately 725 metres of the total approximately 4,000-metre-long Grebes Nest structure. These holes intersected the Grebes Nest Vein at depths ranging from 40 metres to 125 metres vertically below surface. In addition, recent surface trenching has exposed massive mineralized vein material that has been interpreted to be the surface outcrop of the Grebes Nest Vein that was intersected in drill hole GS-13-10.
The three drill holes intersected mineralization that has been interpreted to be the Grebes Nest vein which trends northwest-southeast and is steeply dipping. Drill hole GS-13-10, located in the same plane as previously reported holes, GS-13-07 and GS-13-09, intersected the Grebes Nest vein structure at approximately 50 metres vertically below surface. The intersection is midway between surface and the drill hole GS-13-09 intersection reported previously in a press release dated July 18, 2013.
Drill hole GS-13-14, located approximately 200 metres east of drill hole GS-13-10 and 625 metres east of drill hole GS-13-08 (previously reported in a press release dated July 11, 2013) intersected the Grebes Nest Vein structure approximately 70 metres vertically below the surface. This drill hole also tested two separate vein structures located 20 metres and 125 metres vertically below surface.
Drill hole GS-13-15, located approximately 100 metres east of drill hole GS-13-14 and 725 metres east of drill hole GS-13-08 (previously reported in a press release dated July 11, 2013), intersected the Grebes Nest Vein structure approximately 40 metres vertically below surface. Early drill results indicate that the vein is pinching both along strike and down depth in this area. However, holes to the east and west of GS-13-15 indicate that the pinch extends over a short distance along strike. Further drilling in this area will aid in the defining of the extent of the pinch zone.
Preliminary interpretation of the drill results indicates that the western part of the target area of the mineralized Grebes Nest structure maintains a relatively uniform width along strike and within a vertical depth of 100 to 125 metres below the surface. The drill intersections also indicate very competent core and good continuity of mineralized material at depth. CFI notes that most of the mineralized material is hosted by metasedimentary rocks (interbedded siltstones and shales, whereas most of the mineralized material at the major fluorspar veins in the general area - the historic Director, Tarefare, and Blue Beach North Mines - are hosted by the St. Lawrence Granite ("SLG")). The metasedimentary rocks in the St. Lawrence area are older than the SLG and early geological mapping indicates that the Grebes Nest area is underlain by interlayered pink rhyolite sills, similar in composition to the SLG, which intruded the metasedimentary rocks. The structure that has been identified by the drill program is a late phase event that cuts both the metasedimentary rocks and the sills. The parallel veins, such as the veins identified in drill hole GS-13-14 have been known to develop into significant mineable veins in other locations in the St Lawrence area. The significance of parallel veins remains to be evaluated.
The following table shows the detailed results of the second set of drill holes completed by CFI on the Grebes Nest Vein noted in Phase 3 of the Company's 2013 exploration diamond drill program.

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 2013 exploration program was 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 Aluminum Company of Canada ("Alcan") workings.
Phase 2 of the 2013 exploration program was 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 1,000 metres. 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.
Phase 3 of the 2013 exploration program was designed to evaluate the Grebes Nest mineral property, namely the Grebes Nest vein which was identified in the 1940s. The vein was exposed on the east side of Little Lawn Harbour where the structure is approximately 1 metre wide and dips to the north at -70 degrees. Prospecting in the late 1940s traced the structure, through a series of trenches, to the southeast for a reported distance of 3.2 kilometers. In the late 1940s, a 20 metre deep exploration shaft was sunk on the vein about 500 metres east of the coast. A drift was driven along the vein for 60 metres and a number of short cross-cuts were developed. In 1949, five short drill holes were completed approximately 1 km southeast of the shaft and to the south of the projected strike of the structure. These drill holes identified a number of narrow veins in the metasediments. Due to the remote location of the showing and the adequate reserves at the operating mines owned by Alcan, no additional work was undertaken.
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 Phase 1 drill holes have been completed together with 26 additional drill holes in Phase 2 (19 holes in south extension Director Vein and seven holes at Hares Ears Vein) and 24 drill holes in Phase 3 (Grebes Nest area) of the 2013 exploration program. Assay results for remaining completed drill holes in Phase 2 and Phase 3 are pending.
Historic exploration data indicates that there are more than 40 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).
