EARLY EXPLORATION UNCOVERS TWO NEW INTERESTING SECTORS (NAJA AND MINI-PAUL ZONES)
DAN: TSX-V (Canada) JE9N: FSE (Germany) DRRSF: OTC BB (USA)
SAGUENAY, QC, Feb. 18, 2015/CNW/ - Arianne Phosphate (the "Company" or "Arianne") (TSX VENTURE: DAN) (FRANKFURT: JE9N) (OTCBB: DRRSF), a development-stage phosphate mining company, advancing the Lac à Paul project in Quebec'sSaguenay-Lac-Saint-Jean region is pleased to report an updated NI 43-101 resource estimate on its Paul Zone totaling 702.7 million tonnes at 7.16% P2O5with a 4.0% P2O5 cut-off grade in the measured & indicated category.(1) This NI 43-101 updated resource estimate was completed by GoldMinds Geoservices Inc., based on last fall's diamond drilling campaign (Paul Eastern Extension) and a complete geological remodeling of the Paul Zone (Paul and its Western Extension).
Through further exploration activities completed last fall, Arianne has identified new measured and indicated resources on Paul Eastern Extension of 12.5 million tonnes at 6.31% P2O5with a 4.0% P2O5cut-off grade.(1) Additionally, an updated resource estimate from the remodeling on Paul Zone and its Western Extension now amount to 690.2 million tonnes at 7.18% P2O5with a 4.0% P2O5cut-off grade in the measured & indicated category. In total, Arianne's updated resource estimate now shows a 5% increase in measured and indicated resources (702.7 Mt vs 668.7 Mt) over its previously announced resources released on October 14thof 2014.
"The work that we have done, and results that we have received, continue to expand what is already one of the world's largest Greenfield phosphate rock projects" said Jean-Sebastien David, Arianne Phosphate's COO. "One of the goals we had looked to accomplish for the Company was the ability to show a 50 year life of mine and, as drilling has expanded the Paul Zone to the west and now to the east, we certainly continue to advance towards that goal."(2)
The total combined mineral resources estimate for Paul's main Zone and both its extensions is shown in Table 1broken down by category.

Along with Paul Easternextension, Mini-Paul and Naja underwent surface exploration work during summer 2014. Moreover, Naja Zone was tested with one diamond drill hole during the fall campaign. It is believed that both Mini-Paul and Naja show strong potential for phosphate occurrence, Figure 1locates those 3 areas.
Paul Eastern Extension
The drilling program on Paul Eastern Extension totalled 2 782 meters over 14 holes (PAU-14-170 to PAU-14-183). It had been designed to test the aeromagnetic anomaly associated with this sector. A total of seven (7) sections spaced between 100 to 300 meters were drilled over 1.2 km along the anomaly. Figure 2shows the drill holes locations and the drill sections, while coordinates and technical data are shown in Table 2below.

Data used for the estimate of Paul Zone and its Western extension:
One hundred sixty (160) diamond drill holes on Paul Zone (Pau-08-01 to Pau-14-160); Two (2) trenches on Paul Zone; Total drilled length on Paul Zone of 40 653 meters; Total trenched length on Paul Zone 18 meters 13 587 assay results for P2O5, TiO2, SiO2, Fe2O3, AL2O3, CaO, K2O, Na2O, MnO & MgO; 4 460 deviation data; 1 415 lithological description records.
Nine (9) diamond drill holes on Western Extension (Pau-14-161 to -169); Six (6) trenches on Western Extension; Total drilled length on Western Extension of 1 323 meters; Total trenched length on Western Extension of 54 meters 475 assay results for P2O5, TiO2, SiO2, Fe2O3, AL2O3, CaO, K2O, Na2O, MnO & MgO; 412 deviation data; and, 65 lithological description records.
Parameters for the estimate are:
3 meters Composites; Rectangular blocks of 10mE x 10mN x 15mZ meters; The Paul Zone is divided into three envelopes (Figure 3): nelsonite, mineralized anorthositic gabbro and mix envelope (combination of the latter two). The nelsonite envelope is generally located to the north and all along the deposit, while mineralized anorthositic gabbro envelope is located, in majority, to the south and only in the central and western part of Paul zone (from cross section S2W to S20W). The third envelope (mix) is generally found in the Eastern portion of the deposit directly to the south contact with the nelsonite envelope (from cross section S2W to S10E). Between cross sections S4E and S7E another envelope of mineralized anorthositic gabbro is present directly to the south of the mix envelope. Densities are as follows: Nelsonite envelope 3.57 t/m³ fixed density; Anorthositic gabbro envelope 3.05 t/m³ fixed density; Mix envelope 3.19 t/m³ fixed density;
Grades were estimated using inverse distance squared interpolation. For the Paul zone four (4) runs with the following parameters were used: runs one and two with a number of composites limited to fifteen (15) and to a minimum of 10 with a maximum of five (5) from the same drill hole. Passes three and four with a number of composites limited to fifteen (15) and to a minimum of five (5) with a maximum of five (5) from the same drill hole. A variable direction search ellipsoid was used for the grade estimation. For run one (1) the search ellipse size is 150 x 150 x 35 meters; the search ellipses were identical for passes two (2) and three (3) 250 x 250 x 50; for the pass four (4) a larger ellipse was used 350 x 350 x 75m. The classification parameters for Paul Zone were: Measured with at least two (2) drill holes within a 75 x 75 x 30 m variable direction ellipse (for all categories). Minimum of 6 composites. Indicated with at least two (2) drill holes in a 150 x 150 x 60 m variable direction ellipse. Minimum of 6 composites. Inferred with a drill hole with five (5) composites in 350 x 200 x 90 m variable direction ellipse.
There are only two envelopes, nelsonite and mineralized anorthositic gabbro on the Western Extension. Same estimation parameters than Paul Zone were used. The classification parameters for Paul Western Extension were: Measured with at least two (2) drill holes within a 60 x 60 x 30 m variable direction ellipse (for all categories). Minimum of 8 composites. Indicated with at least two (2) drill holes in a 120 x 120 x 60 m variable direction ellipse. Minimum of 6 composites. Inferred with a drill hole with five (5) composites in 350 x 200 x 90 m variable direction ellipse.
QA/QC procedures included blanks and standards are in line with expected values.
Current Mineral Reserves
The Paul Zone is the main zone of the phosphate Lac à Paul Project. According to the Company's Feasibility Study (FS, released October 24, 2013), the Paul deposit alone currently has proven and probable reserves of 472 million tonnes of ore at 6.9% P2O5(cut-off grade of 3.5% P2O5) and is projected to have a mine life of roughly 26 years. The mineral resource estimate (released March 7, 2013) which was used to establish these reserves reported 590 Mt of measured and indicated resources at 7.13% P2O5with a cut-off grade of 4.0% P2O5.
Naja Zone
The 213 meters long drill hole NAJ-14-01 reported an intersection of 131.9 meters along the hole at 6.58 % P2O5. These results, combined with those obtained from CDN-12-04, a short hole drilled in this area during 2012, allowed for the interpretation of a mineralized zone ranging 40 to 50 meters in true thickness with a dip of about 63° to the south. Additional drilling is required to estimate potential resources associated with the magnetic anomaly recognised over 2.4 km forming the Naja Zone.
Figure 4shows the drill holes location on Naja Zone while coordinates and technical data on the drill holes are shown in the Table 11.

There were 74 samples (including QA/QC procedures), from drill hole NAJ-14-01, sent to ALS Chemex Inc. from Val d'Orto be analysed for major elements, including P2O5, by the ME-XRF06 method. Table 12below shows the intersections obtained along drill holes (true width are roughly 35 % of the intersection length) on the Naja Zone, with P2O5grades obtained. Overburden ranges from 2.8 to 9.2 vertical meters.

| Drill Hole | From (m) | To (m) | Length along the
drill hole (m.) | P2O5(%) | | NAJ-14-01 | 3.20 | 145.10 | 131.90 | 6.58 | | including | 37.20 | 90.00 | 52.80 | 8.05 | | CDN-12-04 | 21.00 | 27.00 | 6.00 | 6.06 | | and | 44.50 | 51.00 | 6.50 | 6.59 | | CDN-12-02 | 42.00 | 51.00 | 9.00 | 4.04 |
Surface field work carried out during summer 2014 in and around the magnetic anomaly led to the identification of Naja as holding strong potential for phosphate.
Table 13shows the locations and P2O5grades of 64 grab samples collected during that period. Among these, 55 have returned values greater than 5% P2O5, 25 of which have a grade above 10 % P2O5. Laboratory analysis were performed by ALS Chemex Inc.
