Eastmain Reports 4.9 g/t Au over 45 metres from Eleonore South JV
TORONTO, ONTARIO--(Marketwired - May 2, 2017) - Eastmain Resources Inc. ("Eastmain" or the "Company") (TSX:ER) is pleased to announce the receipt of assays from the first 9 drill holes from the 14-hole, Phase 2 drilling program at the Éléonore South Joint Venture ("ESJV") property. The 14-hole program consisted of 2,733 m of drilling and was completed in early April (see FIGURES 1 and 2 and Table 1, below). Assays are pending on the remaining 5 holes. The results of the Phase 1 program (see PR dated November 21, 2016) and the results of the Phase 2 program will be used to plan follow-up exploration on the JV property in the second half of 2017.
Highlights from Éléonore South JV intercepts include:
- ES17-64 - 4.88 g/t Au over 45.0 m, including 13.0 g/t Au over 10.5 m (which includes 37.9 g/t Au over 3.0 m)
- ES17-60 - 1.89 g/t Au over 22.5 m, including 16.5 g/t Au over 1.5 m
- ES17-60 - 0.52 g/t Au over 52.5 m
- ES17-61 - 0.91 g/t Au over 16.5 m
The ESJV diamond drilling program tested an area extending approximately 2 km, within a 4 km by 0.5 km prospective corridor, southwest from the Sirios/ESJV boundary. Specifically, drilling targeted the Moni and Trench prospect areas within a tonalite intrusion, and the tonalite contacts with metasediments further to the east. This large gold-bearing system is preliminarily interpreted as a late-stage hydrothermal-magmatic phase directly related to the tonalitic intrusion. The best drill intercept to date is 4.88 g/t Au over 45.0 m, including 37.9 g/t Au over 3.0 m in hole ES17-64, approximately 150 m southwest of the boundary (see FIGURE 2).
Claude Lemasson, Eastmain President and CEO commented, "Today's results represent an important and exciting advancement in our understanding of the gold-mineralized corridor on the Éléonore South property. The highlighted holes' broad intervals and high grades confirm our thesis that there is significant mineralization in and near the tonalite intrusion. This new information will be used to plan the JV's summer/fall 2017 exploration program with our partners, Goldcorp and Azimut."
Prospective Corridor Drilling
Hole ES17-64 was drilled 25 m west, and 25 m up-dip, of the Phase 1 hole ES16-51 (0.62 g/t Au over 79.1 m, incl. 5.00 g/t Au over 4.0 m). A 45 m-wide mineralized interval (4.88 g/t Au over 45.0 m) is hosted in tonalite with generally less than 1% arsenopyrite and pyrrhotite as disseminations or veinlets. Within this broad interval, higher grade intersections (37.9 g/t Au over 3.0 m and 15.1 g/t Au over 3.0 m) occur in strongly silicified tonalite carrying 3 mm to 10 mm wide clusters of visible gold, partially controlled by a tight quartz-chlorite stockwork and moderate biotite alteration (see PICTURES 1 and 2).
Hole ES17-60 targeted the interpreted SW strike extension of the Cheechoo discovery. Four intervals were encountered within a 144 m-wide anomalously mineralized core interval (all samples greater than 0.1 g/t) in albite and biotite altered tonalite with disseminated pyrite, pyrrhotite and arsenopyrite. Of the four mineralized intervals, one intercept (1.89 g/t Au over 22.5 m including 16.5 g/t Au over 1.5 m) contains disseminated arsenopyrite and bands of albite-actinolite alteration.
Hole ES17-61 was drilled 100 m east of hole ER17-60 and targeted the SW extension of the Cheechoo discovery. An interval (0.91 g/t Au over 16.5 m) was obtained in tonalite and pegmatite carrying disseminated arsenopyrite. Two millimetre-scale grains of visible gold were observed within this interval.
Further details regarding the description and interpretation will be provided once all results have been received.

Drill core samples were sent to ALS Minerals in Val-d'Or, Quebec. Gold was analyzed by fire assay with atomic absorption and gravimetric finish for grades above 3.0 g/t Au. Samples were also analyzed for a 48-element suite using ICP. Azimut applies industry-standard QA/QC procedures to the program. Certified reference materials, blanks and field duplicates were inserted in all drill core shipments to the laboratory.
