Eastmain Resources Drilling Continues to Intersect High-Grade Gold
(firmenpresse) - TORONTO, ONTARIO -- (Marketwired) -- 01/04/17 -- Eastmain Resources Inc. ("Eastmain" or the "Company") (TSX: ER) is pleased to announce additional assay results from its ongoing, 63,300 m drill program at the Clearwater Project, which includes the Eau Claire deposit, in James Bay, Quebec (see ).
These results are from 18 holes (5,285 m) of drilling for a total of 50 holes (17,516 m) to date, from three drill rigs. A fourth rig is now commissioned to accelerate the program. A summary of significant assay results and drilling data is presented in Tables 1, 2 and 3 below.
Highlights include:
Claude Lemasson, Eastmain President and CEO commented, "Drilling continues to return excellent results from our open pit and shallow underground definition program on the Eau Claire deposit. The infill drilling results are confirming our expectations within the current resource while tightening the drill spacing to enhance vein continuity. A fourth drill is now arriving onsite and we remain on track to deliver an updated mineral resource estimate in 2Q2017."
DRILLING RESULTS - EAU CLAIRE
Infill drilling reported at the Eau Claire deposit in this news release includes 11 drill holes (3,780 m) to a maximum vertical depth of 270 m. A total of 34 drill holes (10,905 m) are now complete. Drilling to date is successfully developing vein continuity within the mineral resource and improving the known grade thickness within the eastern 450 West zone. (See ) Mineralization remains open at depth and to the east.
Drilling continues to intersect mineralization within a potential open pit and shallow underground mining envelope. The current program is tightening the nominal drill spacing to approximately 25 m, in preparation for the upcoming mineral resource estimate update which will provide the foundation for a Preliminary Economic Assessment scheduled for completion in late 2017. See press releases dated and for previous drilling results.
DRILLING RESULTS - SNAKE LAKE
The second set of drilling results from the Snake Lake target includes 7 exploration drill holes (1,505 m) for a total of 16 holes (3,608 m) now complete at the Snake Lake Target. Drilling is testing a shallow 700 m long by 200 m wide corridor of gold mineralization located 1.8 km east of the Eau Claire Deposit along the Clearwater Deformation Zone. A gold mineralized sulphide rich zone of altered basalt flows and interlayered tuffaceous rocks has been identified in the central portion of the corridor. Quartz-tourmaline gold mineralization similar to the Eau Claire deposit is also identified in the corridor, related locally to shearing. Eastmain will be reviewing these results with a view to further testing of both types of mineralization. (See )
GOLD MINERALIZATION - EAU CLAIRE
Gold mineralization at the Eau Claire gold deposit is generally located within structurally-controlled, high-grade en-echelon quartz-tourmaline veins and adjacent altered rocks. The vein system is predominantly hosted within a thick sequence of massive and pillowed mafic volcanic flows, interbedded with narrow intervals of volcaniclastic sedimentary rocks. Both flows and sediments have been intruded by multiple phases of felsic and porphyry dykes. Host rocks have been folded and deformed (sheared) through several deformation events. The gold bearing veins may occur as thin fracture fill with tourmaline and develop along an easterly strike and a southerly dip (450W zone) into thick quartz-tourmaline veins with zoned tourmaline+/-actinolite+/-biotite+/-carbonate alteration halos which can measure up to several metres in thickness.
GOLD MINERALIZATION - SNAKE LAKE
Gold mineralization at the Snake Lake occurrence is similar to the Eau Claire deposit. Quartz tourmaline veins are hosted within a thick sequence of basalt flows, tuffs and interbedded metasedimentary rocks which have been intruded by felsic dykes. As at Eau Claire, the entire sequence has been heavily deformed and sheared resulting in development of a deformation zone with strong and extensive foliation and local shearing. Significant zones of sulphide mineralization of up to 15% (pyrite, pyrrhotite, +/- arsenopyrite +/- chalcopyrite) are also reporting gold mineralization within the deformation zone.

The design of the Eastmain Resources' drilling programs, Quality Assurance/Quality Control and interpretation of results is under the control of Eastmain's geological staff, including qualified persons employing a strict QA/QC program consistent with NI 43-101 and industry best practices. The Clearwater project is supervised by Eastmain's Project Geologist, Michel Leblanc P. Geo.
Drill core is logged and split with half-core samples packaged and delivered to ALS Minerals laboratory. Samples are dried and subsequently crushed to 70% passing a 2 mm mesh screen. A 1000 gram subsample is pulverized to a nominal 85% passing 75 micron mesh screen. The remaining crushed sample (reject) and pulverized sample (pulp) are retained for further analysis and quality control. All samples are analysed by Fire Assay with an Atomic Absorption (AA) finish using a 50 gram aliquot of pulverized material. Assays exceeding 5 g/t Au are re-assayed by Fire Assay with a Gravimetric Finish. Eastmain regularly inserts 3rd party reference control samples and blank samples in the sample stream to monitor assay performance and performs duplicate sampling at a second certified laboratory. For 2016, approximately 10% of samples submitted are part of the Company's laboratory sample control protocols.
