TORONTO, ONTARIO–(Marketwired – Dec. 12, 2016) – Eastmain Resources Inc. (TSX:ER) (“Eastmain” or the “Company”) is pleased to announce results from its completed 2016 trenching and channel sampling program on its 100%-owned Eastmain Mine Project, located in James Bay, Quebec.
These results are from a total of 1,804 m2 of trenching and channel sampling completed on the Julien and Suzanna targets, located 2.5 km and 2.9 km respectively, to the northwest of the historic mine site. A total of 3,180 m2 has been reported. Significant assay results are summarized in Tables 1 and 2 below and presented in FIGURES 1 TO 5.
Highlights include:
- Channel J3-6: 45.1 g/t Au, 26.5 g/t Ag and 0.61% Cu over 2.0 m, including 85.5 g/t Au, 48.0 g/t Ag and 1.09% Cu over 1.0 m
- Channel J3-5: 4.81 g/t Au, 10.3 g/t Ag and 0.44% Cu over 6.5 m, including 13.5 g/t Au, 28.0 g/t Ag and 1.17% Cu over 2.0 m
- Channel J4-3: 5.04 g/t Au, 8.34 g/t Ag, 0.59% Cu over 2.5 m, including 10.7 g/t Au, 13.9 g/t Ag, 1.26% Cu over 0.5 m
- New mineralized structures have been identified
Claude Lemasson, President and CEO of Eastmain Resources commented, “We’re very encouraged by the presence of these high gold, silver and copper grades in our channel sampling. Our 2016 exploration program is demonstrating a strong potential for the historic mine site mineralization to extend west-northwest, as well as identifying new structures nearby.”
TRENCHING PROGRAM
The 2016 trenching program exposed high-grade gold-silver-copper mineralization within a bimodal felsic/mafic volcanic sequence, at three targets: Julien, Suzanna and Hillhouse. Each target reported mineralization and geology which supports continued exploration. The most prospective assay results to date are coming from the Julien target, located approximately 300 m northeast of the northwest striking Eastmain mine trend.
The mineralization identified by trenching coincides with historic soil geochemical anomalies and locally to electromagnetic trends obtained by Eastmain in previous years. Further surface exploration will focus on extending the mineralized trends discovered in the new trenches. Eastmain will apply its geochemical and geophysical databases to locate additional mineralized zones and define future drill targets.
Trench EM16-J1 (200 m2) tested a limited strike length electromagnetic anomaly. The source of the conductor corresponds to a mineralized contact between felsic and mafic volcanic rocks and returned 0.65 g/t Au over 1.0 m.
Trench EM16-J3 (600 m2) is located just east of Julien Lake, and adjacent to a mineralized outcrop with grab values of 30.9 g/t Au, 24.9 g/t Ag and 1.12% Cu (see Fiscal Year 2013 Management’s Discussion and Analysis). The trench exposed the surface expression of the mineralized zone intersected in hole EM16-76, that returned 219 g/t Au, 153 g/t Ag and 2.54% Cu over 2.0 m (including 752 g/t Au, 464 g/t Ag and 4.47% Cu over 0.5 m) (Press release November 14th, 2016). The best values are from channel J3-6 that returned 45.1 g/t Au, 26.5 g/t Ag and 0.61% Cu over 2.0 m including 85.5 g/t Au, 48.0 g/t Ag and 1.09% Cu over 1.0 m. The gold mineralization is closely associated with a mineralized quartz vein located within in a silicified sulphide mineralized felsic volcanic rock.
Trench EM16-J4 (487 m2) exposed high grade mineralization 190 m west-southwest of trench EM16-J3, and 65 m west of Julien Lake, centered on the Julien showing (surface samples values ranging to 27.3 g/t Au, 18.1 g/t Ag and 0.70% Cu) discovered by Placer Dome in 1982. The gold mineralization is hosted in a mineralized quartz vein, varying in thickness up to 1.2 m. The quartz vein is mineralized with pyrite, pyrrhotite and chalcopyrite and is injected into a sheared and strongly biotitized basalt unit. The sheared basalt is also gold bearing, returning up to 1.09 g/t Au over 0.5 m. The best assay from trench EM16-J4 is from channel J4-3 returning 5.04 g/t Au, 8.34 g/t Ag and 0.59% Cu over 2.5 m including 10.7 g/t Au, 13.9 g/t Ag and 1.26% Cu over 0.5 m.
At the Suzanna Zone, Trench EM16-S2 (517 m2) targeted a moderate electromagnetic conductor. The exposed rock presents an intensely altered basalt composed of quartz, biotite and fuchsite. When the alteration is associated with disseminated sulphide mineralization (pyrrhotite, chalcopyrite) gold mineralization is also present. The best gold value is from channel S2-20 returning 3.96 g/t Au over 1.0 m including 7.13 g/t Au over 0.5 m.
Significant results from the final portion of the 2016 trenching program is presented in Table 1 below.
