TORONTO, ONTARIO–(Marketwired – Aug. 30, 2017) – Eastmain Resources Inc. (“Eastmain” or the “Company”- (TSX:ER)(OTCQX:EANRF) is pleased to announce the final assays from 12 drill holes (7,469 m), part of its 13,000 m drilling program at the Eau Claire gold deposit, located in James Bay, Québec (see FIGURES 1-5). These results have been incorporated into the deposit’s wireframe model and delivered to SGS Geostat for inclusion in the mineral resource update expected in September. Exploration continues with two drills. The Company’s 100%-owned Clearwater Project hosts the Eau Claire gold deposit.
Drilling Highlights Include:
- New shallow visible gold mineralization in quartz veining identified approximately 1.0 km SE of Eau Claire’s 450W Zone outcrop
- ER17-771 – 226 g/t Au over 0.5 m – vertical depth of 69 m
- High Grade Schist (“HGS”) drilling using an oblique, shear parallel hole confirmed the predicted locations of HGS-02 and HGS-04 veins in the updated resource model
- ER17-777 – 5.84 g/t Au over 16.8 m, including 55.5 g/t Au over 0.5 m
- ER17-777 – 8.71 g/t Au over 5.5 m, including 64.0 g/t Au over 0.5 m
- ER17-777 – 3.38 g/t Au over 10.2 m, including 6.36 g/t Au over 2.5 m
- Other Deep Domain exploration highlights include:
- ER17-786 – 34.6 g/t Au over 1.1 m
- ER17-782 – 15.9 g/t Au over 2.1 m, including 28.1 g/t Au over 1.1 m
- ER17-775 – 2.50 g/t Au over 10.1 m including 11.5 g/t Au over 0.5 m
Claude Lemasson, Eastmain President and CEO, commented, “We are impressed with the ongoing drilling results. In particular, down-plunge hole ER17-777 cut multiple HGS vein intercepts and provided more data to the model regarding the relation of HGS-02 and HGS-04 to each other, and the behaviour of other HGS-type veins. Interestingly, hole ER17-771, targeting Deep Domain mineralization, drilled 226 g/t Au over 0.5 m in a new area of shallow mineralization southeast of the deposit. With minimal surrounding information, we intend to conduct significant follow-up in this area.”
The completed 13,000 m program was initiated to further define three important resource objectives:
- HGS Veins:
- To demonstrate continuity of the HGS veins with several oblique, shear parallel holes; successful intercepts are providing greater understanding of the HGS mineralization and help outline future drilling targets
- Deep Domain Exploration:
- To further develop and improve vein continuity within portions of the Deep Domains identified in the 2015 Eau Claire mineral resource estimate; holes in these domains are principally within the 400 m – 700 m depth range, targeting drill spacing of 50 – 75 m from historic holes
- Additional Exploration
- To develop targets for testing from current interpretations of the 450W and 850W zones which may expand the mineral resource envelope
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.
TABLE 1: Highlights from Eau Claire Drilling 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 to perpendicular as possible and true widths are estimated to be 75%-85% of downhole widths with the exception of hole ER17-777 from which true width cannot be determined.|
|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.|
High Grade Schist (HGS) Exploration
Hole ER17-777 drilled near-parallel to HGS-02, confirming the interpreted positions of the main HGS veins (see FIGURE 2 and 3). Highlights include 3.51 g/t Au over 4.5 m, 1.72 g/t Au over 3.0 m and 3.72 g/t Au over 2.5 m in HGS-02 and 12.4 g/t Au over 2.0 m, 7.88 g/t Au over 2.5 m and 20.3 g/t Au over 1.6 m in HGS-04. In addition, the hole encountered other HGS-style veins paralleling HGS-02. Additional examination of historic drilling will be conducted in this area to facilitate potential re-classification of QT to HGS-type veins.
Deep Domain Exploration (400 m – 700 m depth)
Seven drill holes testing the Deep Domains below 400 m depth are reported with 6 holes intersecting interpreted vein extensions to veins identified in these Domains between 2003 and 2009 (see FIGURE 4).
Hole ER17-771 intersected 7.72 g/t over 1.3 m, located 70 m up-dip and to the northeast of hole ER04-44 (18.0 g/t over 1.5 m). The hole intercepted mineralization at 548 m vertical depth.
A narrow high-grade gold interval of 226 g/t Au over 0.5 m was also intersected at 69 m vertical depth in hole ER17-771, collared south of Tonalite Lake. This intercept bears visible gold in a quartz vein with associated tourmaline and biotite. The vein is located outside of the Eau Claire mineral resource envelope in a minimally explored area of the property south of the deposit. Evaluation of this intercept and related geology in historic adjacent holes and at surface is underway to specifically target this mineralization.
Hole ER17-775 tested the extension of hole ER03-29 which intersected 2 deep intervals (an upper 1.51 g/t Au over 2.5 m and lower 18.0 g/t Au over 1.5 m), at 547 m depth and 7.5 m apart. Hole ER17-775 encountered the projected extension of ER03-29 veins intersecting a single interval 2.5 g/t Au over 10.1 m including 11.5 g/t Au over 0.5 m, 13 m to the east.
Hole ER17-778 tested the same Deep Domain as ER03-29 and ER17-775, approximately 190 m to the east and approximately 100 m deeper than hole ER17-775. This hole returned a mineralized interval 1.99 g/t Au over 6.3 m, including 5.31 g/t Au over 1.1 m, at 642 m vertical depth.
Hole ER17-786 tested the Deep Domain identified initially by hole ER04-45 which intersected a stacked interval of 3 veins (4.94 g/t Au /over 1.70 m, 3.71 g/t Au over 1.6 m and 4.99 g/t Au over 6.50 m) within a core interval of 19.0 m at a vertical depth of 677 m. Hole ER17-786 intersected the projected vein zone 55 m due east of hole ER03-45 returning 11.8 g/t Au over 1.0 m.
Hole ER17-782 intersected 15.9 g/t Au over 2.1 m approximately 100 m up-hole of the projected Deep Domain target, at a vertical depth of 556 m (see FIGURE 5). This intercept is not part of the documented vein array. It is most closely associated to the previously reported HGS intercept in hole ER17-774 of 30.8 g/t Au over 4.1 m at a vertical depth of 529 m located 140 m to the east (see press release dated July 27, 2017). These 2 intercepts are approximately 300 m down-dip of the deepest current limits of the HGS-02 vein and nearby QT veins in the 450W Zone. An undrilled extent of approximately 150 m east to west and 300 m in dip is defined for further exploration drilling.
Additional Exploration Drilling
Several additional holes were completed at shallow depths (<400 m). A total of 4 holes are reported from this exploration, including 2 each targeting the 450W and 850W zones. Holes ER17-780 and ER17-781 tested the 850W Zone with hole ER17-780 encountering numerous narrow intersections characteristic of QT veins including 2 shallow intervals at 81 m and 90 m returning 13.5 g/t Au over 1.0 m and 4.94 g/t Au over 2.5 m, respectively. These intervals appear to extend the interpretation of the flat-lying QT-08 vein approximately 50 m to the east. One interval intersected at 380 m vertical depth returned 27.5 g/t Au over 0.5 m in an underexplored area of the 850W Zone.
Holes ER17-783 tested the 450W Zone just below 400 m in depth. The hole extends known mineralization reported in hole ER17-720 (see press release dated June 1, 2017) by 50 m down-dip, intersecting two similar zones of interest between 400 m and 432 m including the HGS-02 vein (2.62 g/t Au over 9.2 m at 410 m vertical depth) and an interpreted extension of QT vein 39 (4.54 g/t Au over 1.0 m).
