September 10th, 2020 – Saville Resources Inc. (TSXv: SRE, FSE: S0J) (the “Company” or “Saville”) is pleased to announce results of fluorine analysis recently completed on select 2008 and 2019 drill core from the Mallard Prospect at Company’s Niobium Claim Group Property (the “Property”), Quebec. The Mallard Prospect is characterized by numerous drill intersections of high-grade niobium, with variably associated high grades of tantalum, phosphate, and fluorspar.
The assay program was initiated to quantify the fluorspar content (based on fluorine content) of previously sampled (2008, 2019) fluorspar-bearing carbonatite drill core, which characterize a more than 600 m long trend, based on lithological core logging (see news release dated July 23rd, 2020). Several of the 2008 drill holes had intersected weak to strongly fluorspar mineralized carbonatite; however, only the highest-grade intervals, based on core logging, were assayed for fluorine at that time. Collectively, the 2008, 2010, and 2019 drill results have outlined a mineralized fluorspar trend, within the primary niobium trend, which is broader and more extensive than previously understood (see Figure 1). Summary highlights include:
•Drill hole EC08-016 has a wider fluorspar mineralized interval than was initially assayed (2008: 30.7% CaF2 over 22.3 m). With the 2020 assays incorporated, the wider zone now assays 21.5% CaF2, over 38.6 m. In addition, the fluorspar zone is accompanied by moderate grades of niobium, tantalum and phosphate at 0.36% Nb2O5, 103 ppm Ta2O5, and 5.3% P2O5, respectively.
• Drill hole EC08-021 had not been assayed for fluorspar historically; however, the recent analysis has confirmed the zone is present with 23.6% CaF2 over 5.0 m, within a larger zone of 8.0% CaF2 over 47.2 m. The zone starts at a core length depth of 69.5 m and confirms the Mallard Prospect’s fluorspar zone continues at high grades to the southeast – individual sample assays of 30.4% CaF2 and 26.9% CaF2 at 95 m depth in EC08-021.
•Drill hole EC19-173 returned 11.9% CaF2 over 6.0 m within a wider interval of 8.4% CaF2, 0.36% Nb2O5, 122 ppm Ta2O5, and 5.4% P2O5 over 22.5 m. The intersection extends at depth the zone in EC10-032 of 14.8% CaF2 over 6.2 m. Collectively, as the most northwestern drill holes completed at Mallard to date, the results in EC10-032 and EC19-173 confirm the zone continues to the northwest along strike.
•EC19- 174A returned 8.5% CaF2 over 6.0 m at 154.0 m depth, as well as another similar interval further down hole.;
(1) All intervals noted are core length. True width is not fully constrained.
The recent fluorine analysis program confirms there is a broad and extensive fluorspar mineralized trend at Mallard, which extends for at least 600 m along strike and is open to the northwest, southeast, downdip, and is interpreted to continue to surface. The trend remains to be delineated significantly outside of the core Mallard area, especially along strike of drill hole EC08-021. The fluorspar mineralization at Mallard is purple and readily observable to the naked eye where grades are of interest.
As a next step, the Company will utilize the dataset to produce a 3D model of the trend and prioritize targets where high-grade fluorspar-bearing carbonatite may overlap with high-grade niobium-bearing carbonatite. As the source of the fluorite is interpreted to be from late stage hydrothermal fluids, which either replaced the host rock (i.e. altered) or was emplaced as veins and breccia infill, there is potential for high-grade and wider widths where conditions are favourable.
