Eastmain Announces Fall/Winter Drill Program at Eastmain Mine Project; Resource Estimate Underway

TORONTO, ONTARIO--(Marketwired - Aug 23, 2017) - Eastmain Resources Inc. ("Eastmain" or the "Company") (ER.TO)(EANRF) is pleased to announce an 8,500 m diamond drilling program at the 100%-owned Eastmain Mine Project, located in James Bay, Québec. Drilling is focused along the 10-km Mine Trend, targeting anomalies identified during a recently completed Induced Polarization ("IP") survey at the Julien, Suzanna and Michel Targets. The IP survey was conducted as follow-up to the early 2017 discovery at Julien (see press release dated January 19, 2017). Drilling is also planned for the historic Eastmain Mine to support resource classification in preparation for the upcoming mineral resource estimate expected in Q4 2017 (FIGURES 1-3). Up to 29 holes are proposed for the program beginning in the first week of September.

Claude Lemasson, Eastmain President and CEO commented: "The very compelling near-surface gold/silver/copper mineralization encountered from Eastmain Mine's initial exploration program warranted significant follow-up. With the initial drilling now supported by significant results from the IP Survey, we are moving forward with an expanded drilling program on the Julien discovery while pursuing other nearby targets within 5-km of the historic mine."

IP Survey Results

A 48-line km OreVision IP Survey was recently conducted over the Julien, Suzanna and Michel Targets covering a 2-km x 2-km area with 100-m line spacings, with depth penetration of +/- 200-m (FIGURE 2 & 3). The survey identified 7 parallel chargeability trends striking southeast parallel to the Mine Trend, extending to the depth of the survey. The highest priority geophysical trend transverses the Julien Target running the entire 2-km length of the grid. The projection of the trend to the SE indicates potential continuation towards the Hillhouse Target located 300 m SE of the IP coverage. A second priority trend extends over the Suzanna Target, also running the length of the existing grid. Several of the strong conductive trends are open at depth and along strike. In addition, the IP results indicate a potential extension of the Mine Trend NW, as well as several other parallel mineralized horizons.

2017-2018 Drilling Program

The 8,500-m diamond drilling program will focus on two main objectives:

1. follow-up on the IP survey along the Mine Trend and recent drilling results at the Julien and Suzanna Targets
2. complete the necessary drilling to support resource categorization for a NI 43-101 resource estimate

Details include:

  • IP Survey targets - 17 drill holes (up to 5,500 m) planned to test the OreVision IP anomalies in the Julien, Suzanna and Michel Target areas. Approximately 1,000 m will target the Julien Discovery where drilling in 2016-2017 confirmed a near-surface gold-silver-copper zone located slightly off the Mine Trend, 3 km NW of the historic deposit. Julien drilling highlights include:

    • EM16-92: 24.8 g/t Au, 25.7 g/t Ag and 1.1% Cu over 9.3 m, including 43.1 g/t Au, 50.6 g/t Ag and 2.0% Cu over 4.3 m

    • EM16-93: 10.6 g/t Au, 20.1 g/t Ag and 1.2% Cu over 15.9 m, including 20.4 g/t Au, 36.8 g/t Ag and 2.3% Cu over 7.6 m

    • EM16-94: 7.8 g/t Au, 13.6 g/t Ag and 0.5% Cu over 10.0 m, including 32.7 g/t Au, 14.5 g/t Ag and 1.0% Cu over 1.0 m, and 5.7 g/t Au and 1.3 g/t Ag over 8.5 m
