VAL-D’OR, Quebec, Nov. 20, 2017 (GLOBE NEWSWIRE) -- SOQUEM, a subsidiary of Ressources Québec, is pleased to announce the results of the summer 2017 drilling program on the volcanogenic massive sulphide Zn-Cu-Au-Ag deposit at its B26 Project, situated 90 km west of Matagami in the province of Québec.
The drilling program, which included both exploration and definition drilling on the B26 deposit, was carried out in July and August 2017. A total of 6,588 metres were drilled in 10 drill holes and one wedge. Of these, two holes were abandoned due to excessive deviation, and one hole and the wedge were abandoned due to ground conditions.
The best intervals include the following (lengths reported as true thickness):
1.67 % Cu and 1.06 g/t Au over 6.85 m (1274-17-260);
2.73 % Zn, 0.64% Cu and 114.1 g/t Ag over 3.88 m (1274-17-261);
3.18 % Zn and 36.8 g/t Ag over 6.06 m (1274-17-264);
10.84 % Zn, 0.70 % Cu and 526.4 g/t Ag over 6.86 m (1274-17-266);
4.32 % Zn and 36.8 g/t Ag over 8.44 m (1274-17-268);
1.75 % Cu and 1.31 g/t Au over 7.09 m (1274-17-269).
Two main types of mineralization characterize the B26 deposit. The northern part of the mineralized system is characterized by chalcopyrite veins and veinlets hosted in sericitized and chloritized rhyolite. The southern portion of the system contains mostly disseminated to massive sphalerite, pyrite and galena mineralization, hosted in horizons of aphyric rhyolite. The zones are parallel and the stratigraphy is oriented generally east-west, dipping 87° to the south.
The full analytical results are presented in Table 1 and the technical data is presented in Table 2. A location map shows the position of surface drill holes and two longitudinal sections (copper-rich alteration zone and zinciferous exhalative zone) show the distribution of new drill hole pierce points compared to previous drill holes.
Results include high silver grades, such as 2,550 g/t Ag from 664.2 to 665.2 m in drill hole 1274-17-266. The results of the program will be used in an upcoming resource estimate to be released during the first quarter of 2018.
Olivier Grondin, CEO of SOQUEM, commented, « The latest drill program tightened the spacing of pierce points in strategic areas for the upcoming resource estimate, and identified copper-rich intersections at depth. We anxiously await the results of the estimate, the first to be performed since the high-grade zinc-silver volcanogenic massive sulphide system was identified. »
Stéphane Poitras, P.Geo., Deputy Director of SOQUEM and a qualified person as defined by National Instrument 43-101, has reviewed and approved the scientific and technical information presented in this news release.
Strict QA/QC protocols have been implemented for the B26 Project, including the insertion of certified reference materials (standards) and blanks.
A total of 1,530 half-core samples were sent for analysis at the ALS laboratory of Val-d’Or. The samples were weighed, crushed and pulverized (code ALS Prep-31) and analyzed for the following elements: Ag, Al, As, Au, Ba, Be, Bi, Ca, Cd, Co, Cr, Cu, Fe, Ga, K, La, Mg, Mn, Mo, Na, Ni, P, Pb, S, Sb, Sc, Sr, Th, Ti, Tl, U, V, W and Zn. For Au, a 30 g split was analyzed by fire assay fusion, which involves melting the sample and analyzing the melt by atomic absorption (code ALS Au AA23). Samples grading between 0.5 and 2 g/t Au are reassayed with gravimetric finish (code ALS Au-GRA21). For all other elements, samples are subjected to four-acid digestion (HF-HNO3-HCl-HClO4) followed by inductively coupled plasma mass spectrometry (ICP-MS; code ALS ME-ICP61). Samples grading above 100 ppm Ag or 10,000 ppm Cu, Pb or Zn are reassayed by four-acid digestion followed by inductively coupled plasma optical emission spectrometry (ICP-OES; code ALS ME-OG62). When silver (Ag) grades exceed 1,500 ppm, a 30 g split is analyzed by fire assay with gravimetric finish (code ALS Ag-GRA21).
