Clearwater Project Encouraging Early-Stage Results at Clovis Lake

TORONTO, ONTARIO--(Marketwired - Feb. 11, 2015) - Eastmain Resources Inc. (TSX:ER) announces assay results from regional drilling at its wholly-owned Clearwater Project, located in James Bay, Quebec. 18 drill holes, totaling 5,079 metres, were completed in the Clovis Lake area, which is situated three kilometres east of the Eau Claire gold deposit. The drill program, designed to search for a second gold deposit on the property, tested auriferous quartz-tourmaline veins exposed by earlier trenching. Drill hole ER14-548 intersected a three-metre interval grading 7.19 grams gold per tonne.

Fifteen drill holes were completed over a 700-metre-long corridor, which coincides with an Induced Polarization ("IP") chargeability high and a resistivity low, south of Clovis Lake. This anomaly occurs within felsic volcaniclastic rocks containing graphite and pyrrhotite, flanked by mafic volcanic rocks and quartz-feldspar porphyry. Anomalous gold ranging from 0.20 to 17.8 grams per tonne gold (g/t Au) was intersected in 13 of 15 drill holes over intervals from 0.5 to 16.0 metres. Drill hole 538 intersected a 6.5-metre-wide interval of altered mafic volcanic rock, which assayed 1.72 g/t Au, including a 0.5-metre-wide quartz-tourmaline vein grading 17.8 g/t Au. 21 intercepts exceed current potential open pit cut-off grades at Eau Claire, while seven exceed current potential underground cut-off grades (NR Oct 11, 2012), with intervals ranging from 14.15 g/t over one metre to 17.80 g/t over a half metre (see website for drill plan and table).

Drill hole 543, which intersected a geochemically enriched 16-metre-wide interval of quartz-tourmaline vein and tourmaline-actinolite schist (0.20 g/t Au), included a 0.5-metre-wide vein interval grading 85.1 grams tellurium per tonne. Tellurium is commonly found within the Eau Claire deposit at roughly a one-to-one correlation with gold. Hole 545 intersected a 10-metre-wide interval of vein and altered schist grading 0.43 grams gold per tonne. Several drill holes on the southern side of Clovis Lake intersected wide zones of anomalous gold, indicating a large mineralizing system is still evident three kilometres away from the main deposit area. Further work is definitely warranted in this area.

Three drill holes were also completed on the north side of Clovis Lake to test a quartz-tourmaline vein at surface with rock and channel samples ranging from 0.65 to 62.4 g/t Au. All three holes intersected wide zones of anomalous gold. Hole 549 intersected a 3-metre-wide interval of altered felsic volcaniclastic rocks grading 0.62 g/t Au. Notably all three drill holes intersected from 50 to more than 150 metres of feldspar porphyry ("QFP") at the bottom of each hole. Since Eau Claire is bounded on the south margin (hangingwall) by QFP and the overall morphology of the gold deposit conforms to and is controlled by a QFP dyke swarm, this may indicate that a prospective target in the discovery of a second deposit may be situated further north. Further work is needed to confirm the significance of QFP swarms and controls on gold mineralization in this area.

"The Clovis Lake drill program was successful in finding a repetition of Eau Claire gold deposit geology, structure and mineralization. Thick intervals of quartz-tourmaline veining and associated rock alteration containing anomalous gold values indicates the presence of a large gold system three kilometres east of the deposit. We are extremely encouraged by these early-stage results. Additional drilling is needed to test for continuity, grade and dimension," states Eastmain's President and CEO, Don Robinson.

QP and Quality Control

Dr. Donald J. Robinson P. Geo, President and Chief Executive Officer of Eastmain, Qualified Person under National Instrument 43-101 reviewed and approved the scientific and technical data presented in this press release. Dr. Robinson has supervised the work programs on the Company's properties, visited the properties on multiple occasions, examined outcrops, drill core and trenched areas, reviewed results with on-site geological staff and reviewed both the analytical and quality control results.

Eastmain conducts a quality control program for all of its exploration work, to ensure best practices in the industry from sample shipment and preparation to data collection and analyses. Chemical analysis was completed by ALS CHEMEX Laboratories using a 50-gram split with ICP, AA and gravimetric techniques. Internal standards provided by an independent company and blank samples were inserted for quality control purposes.

About Eastmain Resources Inc. (TSX:ER) Eastmain is a Canadian exploration company with 100% interest in the Eau Claire and Eastmain gold deposits, both of which are located within the James Bay District of Quebec. Eau Claire, our core asset, has superior infrastructure within a favourable jurisdiction and is royalty free.
