The key objectives of field work at Eastmain Mine and Ruby Hill East were to explore for additional gold resources lateral to the Eastmain Gold Deposit and to search for a repetition of the mine horizon on the adjacent and contiguous Ruby Hill East claim block. Rock sampling on the Eastmain Mine property has confirmed four high-priority targets northwest of the A and B Zones of the Eastmain Mine Gold Deposit. Geochemical sampling on the adjacent Ruby Hill East property has defined a continuous gold-in-soil anomaly for a length of 800 metres in the south-central part of the property…

Eastmain Mine
The Eastmain Mine property contains a high-grade gold deposit, with ramp access to underground workings, and surface infrastructure sufficient to house a sixty-person work force, all of which is now accessible by permanent road via Route 167 North. Four high-grade target zones have been confirmed through prospecting and rock sampling northwest of the Eastmain Gold Deposit. Two of the areas (“Hillhouse” and “Julien”) coincide directly with the projected Eastmain Mine horizon and two targets (“Michel” and “Susanna”) are located along a secondary parallel structure, which may be an immediate repetition of the mine sequence immediately west of the main feature. Follow-up trenching and drilling is warranted to test these mineralized corridors.
Hillhouse Target
249 rock samples were collected as part of the 2014 geological targeting program in search of additional resources along the “mine corridor”. The Hillhouse target, which occurs 850 metres northwest of the A and B Zones, consists of a 400-metre long by 150-metre wide area, containing anomalous rock samples, with gold (Au) ranging from 0.5 to 39.5 grams per tonne; silver (Ag) ranging from 0.5 to 25.8 grams per tonne and; copper (Cu) ranging from 0.1 to 2.4%.
Julien Target
The Julien target is situated 1.7 kms northwest of the A and B Zones. This target coincides with a magnetic high in mine corridor rocks extending for a length of 500 metres. The Julien target has been defined by hundreds of anomalous rock samples containing from 0.5 to 27.2 grams per tonne Au; from 0.5 to 28.8 grams per tonne Ag and; from 0.1 to 2.3% Cu.
Susanna Target
The Susanna target is situated 600 metres west of and parallel to the Julien anomaly. This target extends for a length of 375 metres with rock assays ranging from 0.5 to 38.7 grams per tonne (g/t) gold, 0.5 to 26.6 g/t silver and 0.1 to 3.06% Cu.
Michel Target
The Michel target is located 400 metres north of the Susanna anomaly and is defined by two clusters of rock samples ranging from 0.5 to 125.1 g/t Au; 0.5 to 12.5 g/t Ag; and 0.1 to 1.08% Cu.
Ruby Hill East
The adjacent Ruby Hill East claim block covers what has been interpreted as a potential repetition of the mine horizon. This claim block straddles a regional stratigraphic and structural break – a prime target location for ore deposits. This target horizon was screened using regional soil geochemical surveys at 200-metre line intervals and 50-metre stations. Review of 1,132 B-horizon assays indicates there is a significantly gold-enriched soil anomaly, ranging from >10 to 405 ppb Au, across an 800-metre-long interval coinciding with a regional magnetic high in the south-central portion of the claim block.
Prospecting along additional regional conductive horizons at Ruby Hill East yielded results from 0.1 to 1.65 grams gold per tonne in cherty iron formation. This anomaly also coincides with an interpreted repetition of the mine horizon.
2014 exploration very successfully identified new widespread mineralized systems, matching the Au-Ag-Cu signature of the Eastmain Mine Gold Deposit, on both the Eastmain Mine and Ruby Hill East properties. 2015 work will focus on follow-up trenching and drilling of these targets.
Dr. Donald J. Robinson P. Geo, President and Chief Executive Officer of Eastmain, Qualified Person under National Instrument 43-101 reviewed and approved the technical data presented in this press release.
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.
