TORONTO, ONTARIO -- (Marketwired) -- 12/12/17 -- Eastmain Resources Inc. ("Eastmain" or the "Company") (TSX: ER)(OTCQX: EANRF) announces the receipt of assay results from 18 drill holes completed in the fall drilling program at the Eleonore South Joint Venture ("ESJV") property. The 18-hole program consists of 4,443 m of drilling (see FIGURES 1 to 5 and Tables 1 to 3) and was undertaken from August to October, 2017. This completes the Phase 1 drilling by the Joint Venture for the H2/17-H1/18 exploration period.
Eleonore South continues to deliver very encouraging drilling results that complement the previously reported high-grade channel and grab samples, and the announcement of the Moni Trend discovery (see press releases of October 17 and November 16, 2017). New Phase 2 diamond drilling comprising 3,600 m is scheduled for early next year to complete the program. It will follow up on drill results and test new high-grade targets (Moni Trend, See Figure 2).
Drilling Highlights include:
Hole ES17-80: 6.13 g/t Au over 9.0 m (including 22.9 g/t Au over 1.5 m)
Hole ES17-81: 5.93 g/t Au over 1.5 m
Hole ES17-85: 22.4 g/t Au over 1.2 m
Hole ES17-88: 3.15 g/t Au over 24.0 m (including 13.5 g/t Au over 3.0 m,
19.3 g/t Au over 1.50 m)
Hole ES17-90: 4.45 g/t Au over 4.5 m (including 12.4 g/t Au over 1.50 m)
Hole ES17-77: 1.72 g/ Au over 35.5 m (including 23.1 g/t Au over 1.5 m)
and 1.78 g/t Au over 13.4 m (including 11.7 g/t Au over
1.5 m)
Hole ES17-74: 0.45 g/t Au over 87.0 m (including 2.46 g/t Au over 1.5 m,
4.82 g/t Au over 1.5 m)
Observations from Drilling
A significant feature of the mineralized tonalite is the wide intervals of highly anomalous gold mineralization that have been intersected in the current program and in holes completed earlier in 2017. Most significant gold-bearing intervals are found within, or near, large continuous gold-mineralized envelopes with gold values ranging from 50 ppb to 900 ppb Au in core samples and averaging between 0.25 g/t Au and 0.50 g/t Au along drill hole intercepts. Wide interval results from the current drilling notably include:
Hole ES17-74:0.45 g/t Au over 87.0 m Hole ES17-87: 0.49 g/t Au over 76.5 m Hole ES17-75:0.49 g/t Au over 63.0 m Hole ES17-89: 0.57 g/t Au over 19.5 m Hole ES17-77:0.53 g/t Au over 106.0 m Hole ES17-90: 0.50 g/t Au over 123.5 m Hole ES17-80:0.65 g/t Au over 147.5 m Hole ES17-91: 0.61 g/t Au over 15.0 m
These drill results suggest sub-horizontal gold-bearing lens like envelopes, 35 m to 50 m thick, whose upper limits range in depth from 70 m to approximately 150 m vertically. Drilling has identified three (3) tonalite-hosted mineralized lenses or zones, along a 1.4 km northeast-southwest strike, close to the tonalite-metasediment contact. These zones, from SW to NE are intersected by holes ES17-80 and adjacent holes, ES17-74 and adjacent holes and ES17-77 and adjacent holes (See Figure 3).
Within these envelopes the geometry of higher grade sections is still undefined with respect to strike and extent but correspond to strongly silicified tonalite and quartz-biotite stockwork, arsenopyrite and native gold. Native gold has been found in 15 of 18 reported holes. The prospective envelopes appear to be open laterally along the SW-NE trending tonalite-metasediment contact (See Figure 5).
The nearby tonalite-metasediment contact is generally shallow-dipping (20 degrees to 50 degrees ) to the southeast. Exploration opportunity exists parallel to the tonalite-metasediment contact (SW-NE) between identified zones and below, or at, the contact.
At the scale of the intrusion, drilling along the southern limit at or near the metasedimentary contact has confirmed gold potential over a distance of approximately 4 km, from hole ES17-62 in the east to the JT Prospect in the west (see Figure 2). The tonalite-hosted gold-bearing system, from the high-grade Moni Prospect to the southern limit of the intrusion, has a prospective width of 500 m.
A summary of selected assay results from this drilling program are presented in TABLE 1 below. TABLE 2 represents the complete set of significant results.

1. Intervals are presented in core length; true width will vary
depending on the intersection angle of the hole with the
targeted zone, narrow intercepts are believed to represent
60%-80% of true width.
2. Assays presented are not capped.
3. Vertical depth is measured from the surface as a function of
depth and hole inclination to the mid-point of the reported
interval.
Target Types
Exploration since mid-2016 has discovered and focused on two main target types hosted by the tonalite intrusion. Both types are interpreted to be part of an extensive late-magmatic hydrothermal system related to the tonalite intrusion.
1) High-grade gold-bearing quartz-feldspar pegmatitic vein systems with native gold ("Moni-type"). (see press releases of October 17 and November 16, 2017). The extent and geometry of these mineralized systems remain to be further defined, but surface results at the Moni Prospect and further vein identification at the 101 Zone located 400 m to the SW clearly indicate the potential for significant grade and geometric continuity. This target type will be thoroughly tested by drilling during the upcoming Phase 2 drill program in early 2018.
2) Kilometre-scale zones of considerable width characterized by quartz-albite-biotite veinlet stockwork or networks of quartz-albite veinlets of variable density, both accompanied by small amounts of sulphides (arsenopyrite, pyrite, pyrrhotite) and frequently by native gold. This press release reports on drilling targeting this type of mineralization.

This press release and information provided by the operator of the Eleonore JV was reviewed by William McGuinty, P. Geo., Eastmain's VP Exploration and a Qualified Person under National Instrument 43-101.
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.
