CFI Announces Discovery of a New, High-Grade, Fluorspar Vein Close to Former Fluorspar Mines in St. Lawrence NL10:39 EDT Thursday, July 11, 2013
ST. JOHN'S, NEWFOUNDLAND--(Marketwired - July 11, 2013) - Canada Fluorspar Inc. (TSX VENTURE:CFI) ("CFI" or the "Company") is pleased to announce first assay results from three holes drilled under the Company's Phase 3 diamond drilling program at its Grebes Nest property. This new mineralized structure is situated approximately 4 kilometers from the former Tarefare mine and less than 6 kilometers from the former Blue Beach North mine (see location map below). All three drill holes are located on the western part 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. The drill holes completed identified as GS-13-08, GS-13-03, and GS-13-07, with one hole (GS-13-08) intersecting 48.68% CaF2 over 16.85 m.
All three drill holes are inclined at -55° and oriented at Azimuth 034°.

Drill hole GS-13-08 tested the down-dip extension of the Grebes Nest Vein at an old exploration shaft (GN Shaft) approximately 20 metres below the surface. This shaft, which was sunk in the 1940s, is located within an existing open-cut that was mined by a previous operator during the early 1990s. Drill hole GS-13-08 intersected a significant vein structure, with an average grade of 48.68% CaF2over 16.85 m.
Drill hole GS-13-03 intersected two vein structures, the first vein structure intersection had an average grade of 46.57% CaF2 over 1.90 metres, and the second vein structure intersection had an average grade of 68.08 CaF2 over 6.23 m.
Drillhole GS-13-07 intersected the Grebes Nest Vein structure with an average grade of 41.67% CaF2 over 5.58 m.

"This is very exciting news", stated Lindsay Gorrill, President & CEO of Canada Fluorspar Inc., "Based on the 21 holes we have drilled to-date on the Grebes Nest property we have identified fluorspar mineralization along a strike length of approximately 1.5 kilometers and extending to more than 170 metres at depth. We have received assays for only three of the 21 holes, but based on visual observations on drill core by our qualified persons, we are optimistic about the assay results. We look forward to releasing the assays on the remaining drill holes as they become available and plan to continue drilling to confirm the richness of this vein at depth and along strike."
CFI has received assay results for samples collected from drill holes GS-13-08, GS-13-03, and GS-13-07 located along the western part of the Grebes Nest target area. These holes are spaced approximately 100 metres apart, cover a strike length of approximately 425 metres of the total approximately 4,000 metres long Grebes Nest mineralized structure. These holes intersected the Grebes Nest Vein at depths ranging from 90 metres to 110 metres vertically below the surface. In addition, hole GS-13-08, intersected the vein below the old shaft and recent trenching, and has revealed mineralized vein material which is interpreted to be the projection of the Grebes Nest Vein intersected in drill hole GS-13-03.
All three drill holes intersected what is interpreted to be the Grebes Nest main vein which trends northwest and is subvertical. Drill hole GS-13-08 intersected the Grebes Nest vein structure at approximately 100 metres vertically below the surface and tested the mineralization below the old shaft and the pre-existing open-cut on surface.
Drill hole GS-13-03, located approximately 325 metres east of drill hole GS-13-08, intersected a vein structure at 90 metres vertically below the surface as well as the Grebes Nest Vein structure approximately 105 metres vertically below the surface.
Drill hole GS-13-07, tested the Grebes Nest structure below drill hole GS-13-10, and intersected the Grebes Nest vein structure at approximately 110 metres below the surface.
Drill hole GS-13-10, intersected the Grebes Nest Vein approximately 50 metres below the surface, midway between surface and the drill hole GS-13-07 intersection. Assays for this hole are pending.
Preliminary interpretation of the drill results to date indicates that at the western part of the Grebes Nest target area the mineralized structure maintains a relatively uniform strike and width within a depth of 100 metres vertically 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 slates, 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 have 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 the drill hole GS-13-03 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 the results of the first set of drill holes completed by CFI on the Grebes Nest Vein know 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 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 1.0 metre wide and dips to the north at -70 degrees. Prospecting in the late 1940's traced the structure, through a series of trenches, to the southeast for a reported distance of 3.2 kilometers. In the late 1940's, 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 one kilometer 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 the Aluminum Company of Canada ("Alcan") no additional work was undertaken.
Historic mining operations by Alcan on the St. Lawrence 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 26 additional drill holes in Phase 2 (19 holes in south extension Director Vein and 7 holes at Hares Ears Vein) and 21 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 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).
