CFI Announces Assay Results from Drill Holes Completed on the Grebes Nest Property Including One Hole Having an Average Assay of 43.14% CaF2 Over 7.30 Metres07:53 EDT Thursday, August 29, 2013
ST. JOHN'S, NEWFOUNDLAND--(Marketwired - Aug. 29, 2013) - Canada Fluorspar Inc. (TSX VENTURE:CFI)(OTC:CNDFF) ("CFI" or the "Company") is pleased to announce the sixth 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-13-12, located in the same plane as the previously reported drill hole GS-13-11 (press release dated July 18, 2013) intersected the Grebes Nest vein structure having an average grade of 43.14% CaF2 over 7.30 metres and intersected two additional veins down-depth having an average grade of 19.12% CaF2 over 4.00 metres and 55.40% CaF2 over 3.25 metres, respectively. Two additional drill holes, GS-13-16 and GS-13-18, are located about 400 metres and 500 metres, respectively, southeast along strike from drill hole GS-13-12. The new Grebes Nest 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). The three 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-13-12 was inclined at -45º and oriented at azimuth 34º, drill hole GS-13-16 was inclined at -62º and oriented at azimuth 34º and drill hole GS-13-18 was inclined at -66º and oriented at azimuth 34º.

Drill hole GS-13-12 tested the down-dip extension of the Grebes Nest Vein on the same plane as drill hole GS-13-11, a previously reported drill hole (press release dated July 18, 2013) from the second set of assay results reported in the Grebes Nest Phase 3 drilling program. This hole intersected three different vein structures down depth: the first vein structure having an average grade of 43.14% CaF2 over 7.30 metres; the second vein structure having an average grade of 19.12% CaF2 over 4.00 metres; and a third vein structure having an average grade of 55.40% CaF2 over 3.25 metres.
Drill hole GS-13-16 intersected a vein structure having an average grade of 26.80% CaF2 over 2.75 metres.
Drill hole GS-13-18 intersected three different vein structures down depth: the first vein structure having an average grade of 63.91% CaF2 over 2.77 metres; a second vein structure having an average grade of 47.52% CaF2 over 2.60 metres, with lost core of about 0.30 metres; and a third a vein structure having an average grade of 42.58% CaF2 over 2.93 metres.

"I continued to be encouraged by both the width and grade of the Grebes Nest Vein and that the silica content is lower and blastonite, a brecciated fluorite in an admix of microcrystalline quartz and fluorite, is virtually absent compared to the other granite-hosted veins," stated Lindsay Gorrill, President & CEO of the Company. "Grebes Nest Vein has been normally competent material with minor fracturing as compared to most similar veins in the St. Lawrence area and has resulted in better than 95% core recovery from the mineralized intervals. These good recovery results in a much higher level of confidence in calculating the average grade of the intersections."
CFI has received assay results for samples collected from drill holes GS-13-12, GS-13-16 and GS-13-18 located along the western part of the Grebes Nest target area. 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-13-12 is located in the same plane as a previously reported drill hole GS-13-11 (press release dated July 18, 2013). The first and second intersections in this hole were at a vertical distance below surface of about 80 and 90 metres, respectively, while the third intersection was about 110 metres vertically below surface. This vein was tested further down depth with drill hole GS-13-26 and results are pending.
Drill hole GS-13-16, located on the same plane as a previously reported drill hole GS-13-15 (press release dated August 6, 2013), intersected the vein about 70 metres vertically from surface and 30 metres below the drill hole GS-13-15 intersection. This vein was tested further down depth with drill hole GS-13-25 and results are pending.
Drill hole GS-13-18, located in the same plane as previously reported drill hole GS-13-17 (press release dated August 12, 2013) intersected the first and second veins at a vertical depth of about 50 and 60 metres, respectively, from surface while the third vein was intersected about 140 metres vertically from surface.
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 175 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 vein identified in drill holes GS-13-12 and GS-13-18 have been known to develop into significant mineable veins in other locations in the St Lawrence area. The economic and structural significance of the parallel veins remains to be evaluated.
The following table shows the detailed results of the sixth 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 7 holes at Hares Ears Vein) and 30 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).
