GOLD: Winter Drilling Strengthens Model for Large-Scale Intrusive Hosted Gold System at Éléonore South

TORONTO – Eastmain Resources Inc. is pleased to announce the receipt of assay results from 32 drill holes totalling 5,449 m completed during the winter drilling campaign at the Éléonore South Joint Venture (ESJV) Property (Eastmain-Goldcorp-Azimut). This phase completes the H2/2017-H1/2018 diamond drilling program of 50 holes for a total of 9,892 m. Located in the James Bay region of Quebec, Eleonore South is adjacent to the property that hosts the Éléonore gold mine owned and operated by Goldcorp.

Surface exploration and diamond drilling on the Éléonore South property since 2016 (76 holes totalling 15,134 m) have uncovered a large gold-bearing system extending least 2 km in length and 600 to 700 m in width, within a tonalite intrusion in close proximity to the contact with overlying metasedimentary rocks containing:

  • A mineralized envelope with consistently anomalous gold values ranging from 50 ppb to 900 ppb with multi-metre intervals ranging to 0.5 g/t Au characterized by the appearance of one or several networks of quartz veins and veinlets, strong sodic alteration, very low sulphide concentrations (<0.5%) and frequent visible gold grains (“Contact Trend”);
  • Several high-grade zones characterized by; a) clusters of quartz-albite-biotite stockworks accompanied by arsenopyrite, pyrrhotite, pyrite, scheelite and visible gold, and b) quartz-feldspar pegmatitic vein systems with visible gold (“Moni Trend”).

The JT Prospect is a sediment-hosted gold-bearing zone discovered in 2006 situated in stratigraphy at the contact with the tonalite intrusion, 2.5 km to the west of current exploration. Results from 2008 drilling indicate that the tonalite is also mineralized in this area. The JT Prospect and related stratigraphy near the tonalite contact extends the highly prospective zone to a semi-circular shape of approximately 5.5 km in length with considerable upside exploration potential.
