TORONTO, ONTARIO -- (Marketwired) -- 11/06/17 -- Eastmain Resources Inc. ("Eastmain" or the "Company") (TSX: ER) (OTCQX: EANRF) is pleased to announce initial drilling results from 6 holes (3,738 m) of a 15,000 m extension drilling program at the Eau Claire deposit targeting the 400 - 850 m vertical depth levels, located on the 100%-owned Clearwater Project in the emerging James Bay gold camp (see FIGURES 1, 2).
Intercepted High-Grade Schist ("HGS") mineralization demonstrated grades and thicknesses characteristic of this type veining at Eau Claire. Several intercepts of the extensive Quartz-Tourmaline ("QT") vein suite were also encountered in the reported holes, which targeted the 350 m to 550 m vertical depth levels of the deposit.
Drilling Highlights Include:
-- Interpreted extension of the HGS-02 vein by 135 m downdip (ER17-803 -
vertical depth 550 m) and 50 m to the east (ER17-793 - vertical depth
400 m)
-- ER17-803 - 8.7 g/t Au over 11.8 m; incl. 14.0 g/t Au over 5.0 m and
a second interval of 6.3 g/t Au over 12 m incl. 13.5 m over 3.5 m
-- ER17-793 - 4.31 g/t Au over 11.4 m incl. 10.9 g/t Au over 3.3 m
-- HGS veins extend below the known limits of the deposit's defined
resources
-- QT vein intercepts also confirm continuity of this style of
mineralization at depth
Claude Lemasson, Eastmain President and CEO, commented, "We are encouraged by these results downdip as they extend both the HGS and QT veins. Given the broader average widths of the HGS veins and their extension to depth, we expect them to play an important role in future underground mine development. With two drills turning, we look forward to further reporting on our 15,000 m program and commencing our PEA work."
A summary of selected high-grade assay results from this drilling 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. Holes are
generally planned to intersect vein structures as close perpendicular as
possible and true widths are estimated to be 75%-85% of downhole widths.
However, holes reported in this press release have been drilled
obliquely to veins and true widths are estimated to be in the range of
50% of core length.
2. For known mineralized zones, intervals are based on geological
observations and limited compositing of veins. Assays presented are not
capped. Intercepts occur within geological confines of major zones but
have not been correlated to individual vein domains at this time.
3. Vertical depth is measured from the surface to the mid-point of the
reported interval.
4. Italicized & bolded figures represent High Grade Schist vein intercepts
Holes reported in this press release targeted the base of the defined 450W QT and HGS vein systems between 350 m and 550 m vertical depth. To reach this region of the deposit and obtain information in time for the PEA, drills were positioned on the north side of Tonalite Lake and the drill direction was reversed. As a result, intersections reported cut more obliquely to the vein systems but provide important vein location and assay information.
The 15,000 m program consists of expansion and confirmation focused drilling, targeting the 400 m to 850 m vertical depth level in the southeast section of the deposit. The drilling is designed to strengthen resource interpretations in an area of limited drilling. In particular, drilling is focused on the extension of the HGS veins which are understood to develop significant widths and whose importance to the underground development of Eau Claire increased significantly in the recently issued Eau Claire Mineral Resource Update (see press release dated, October 26, 2017).
Drilling results will be incorporated into an updated mineral resource estimate, focused improving and increasing resources from the depth of current deposit limits to the 850 m level. The updated mineral resource will set the foundation for the upcoming Eau Claire Preliminary Economic Assessment ('PEA') expected in 2Q 2018.
