Toronto, Ontario, July 27, 2017 - Eastmain Resources Inc. (“Eastmain” or the “Company”- TSX:ER, OTCQX:EANRF) is pleased to announce assays from 11 drill holes (5,698 m) from its 10,000 m drilling program at the Eau Claire gold deposit, located in James Bay, Québec (see FIGURES 1-4). The Company’s 100%-owned Clearwater Project hosts the Eau Claire gold deposit.
Eastmain intends to provide the results from the 10,000 m program to SGS Geostat for inclusion in the new mineral resource. The upcoming report will define a potential open pit and shallow underground mineral resource and is on track to be delivered in Q3 2017.
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.
estimated to be 75%-85% of downhole widths with the exception of holes 770, 773 and 776 from which true width cannot be determined.
individual vein domains at this time.
Drill hole ER17-776 targeted the HGS-02 vein in the centre of the 450W area of the deposit by drilling into and along the HGS structure (FIGURES 2-3). After intersecting 21.3 g/t Au over 0.5 m in a QT vein, the hole encountered 5 significant mineral intercepts along the HGS-02 vein beginning at a hole depth of 235 m, finally exiting at 378 m. The intervals demonstrate a close spatial relationship to the wire frame developed for HGS-02 vein, confirming mineral continuity along the vein. The drill hole successfully targeted an area of significant HGS-02 intervals from previous drill holes ER13-512 (8.44 g/t Au over 16 m), ER16-597 (5.06 g/t Au over 5 m), ER17-674 (8.31 g/t Au over 13.3 m) and ER16-584 (11.5 g/t Au over 13.5 m). The longest sustained ER17-776 interval along the vein returned 7.09 g/t Au over 35.8 m, located close to the previously mentioned section holes. Several mineralized intercepts in hole ER17-776 also occur near potential intersection points between the HGS-02 vein and several QT veins.
Hole ER17-773 intersected 35.8 g/t Au over 1.0 m, an interpreted QT vein, in an attempt to explore the expected convergence of HGS-02 and HGS-04 vein.
Hole ER17-770 attempted to drill within the plane of the HGS-02 vein along a steeper orientation. The hole intersected narrow QT vein, but appears to have paralleled the HGS-02 structure in its footwall.
Hole ER17-774 (FIGURE 4) intersected an HGS vein, grading 30.8 g/t Au over 4.1 m at a vertical depth of 529 m, approximately 300 m below and down dip of the nearest interpreted HGS vein. As modelled, the vein is hosted within metavolcanics located within the Quartz-Feldspar Porphyry (hanging wall) and Volcaniclastic Sediment (foot wall) bounded structural corridor, suggesting the potential for the vein system, including the previously un-modelled HGS veins to continue at depth. A review of historic (2003-2009) drill core will be initiated in nearby holes, testing for potentially un-sampled HGS mineralization. Additional drilling in this area is currently being planned.
Hole ER17-772 targeted a Deep Domain Zone defined by ER03-29, which reported several mineralized intercepts, including 18.0 g/t Au over 1.5 m at a vertical depth of 547 m, and in hole ER02-06 including 20.0 g/t Au over 1.5 m at a depth of 534 m. Hole ER17-772 intersected the predicted Deep Domain target at 60 m down dip from ER03-29, reporting several narrow intervals of quartz-tourmaline veining with low results.
The deep holes are using NQ diameter drill rods. This will enable follow-up infill drilling to be accomplished through a drill hole wedging campaign to improve targeting of proposed infill intercepts.
Six holes reported tested various areas at Eau Claire including; 2 additional infill holes testing the 450W and 850W Zone; 2 holes testing for shallow satellite mineralization to the northeast of the 450W zone and; 2 exploration holes testing the volcanic stratigraphy between Eau Claire and the Snake Lake Prospect as part of a proposed fence of holes to test for new vein mineralization and assist with mapping the geology between the two areas.
Hole ER17-753 intersected 2 QT veins in the 850W zone within 50 m of surface, including one of 9.9 m interval of 1.11 grams.
Hole ER17-768 tested a deep target in an area where the 450W zone is believed to trend beneath the 850W zone. 4 narrow QT vein intervals ranging from 1.29 g/t Au over 1.0 to 6.8 g/t Au 0.5 m were intersected. Further testing of this area will be considered once resource estimation is complete.
Holes ER17-765 and ER17-767 tested a portion of the stratigraphy midway between Eau Claire and Snake Lake Prospect as part of a fence of holes to map structure and geology in the area linking these two mineralized zones. Gold mineralization was limited to 0.5 to 1.0 m intercepts of QT vein mineralization ranging to 2.95 g/t Au.
Holes ER17-751 and ER17-761 tested an area of the Eau Claire deposit NE of the 450W zone where stripping had previously exposed QT veining at surface. One interpreted extension of a surface vein was encountered at 15 m depth (2.44 g/t Au over 0.5 m) in hole ER17-761.
