(Montréal, April 12, 2017). Osisko Mining Inc. (OSK:TSX, “Osisko” or the “Corporation”) is pleased to announce that it has identified a site (the “Site”) covering approximately four square kilometres for the potential construction of a mill complex that would process mineralized material from the Windfall Lake deposit.  The Site is located near an existing industrial property (the former Domtar Corporation pulp and paper mill) in Lebel-sur-Quévillon, Québec.  A location map of the Site is provided at www.osiskomining.com.

Osisko intends to evaluate the Site location through the environmental assessment process and in the preparation of a feasibility study for the Windfall Lake gold project. The Site is located 11 kilometres from Lebel-sur-Quévillon and 103 kilometres via existing all-weather gravel road networks from the Windfall Lake deposit, and is adjacent to a Hydro?Québec electric substation and a water pumping station.  The Site is located on Crown land immediately southeast of the municipal limit of Lebel-sur-Quévillon.  Osisko holds the mineral exploration titles under the Site.

As part of the ongoing evaluation of the Windfall Lake deposit, Osisko plans to file the Project Description with the federal government (Canadian Environmental Assessment Agency) and the Project Notice with the Québec government (Ministère du Développement durable, de l’Environnement et de la Lutte contre les changements climatiques) in the coming week.

Subject to the results of the full environmental assessment and feasibility study to be completed, the Corporation believes advantages of this Site over construction at Windfall Lake include:

• limiting Windfall Lake infrastructure to mining activity, greatly reducing the environmental footprint;
• access to existing grid power and the Hydro-Québec electrical substation at the Site, eliminating the construction cost of a 103 kilometre power line to Windfall Lake and the corresponding environmental permitting along the power corridor;
• access to the existing water pumping station near the adjacent dormant pulp and paper mill, which has ample capacity for the needs of a potential gold milling complex;
• access to the regional work force centered at Lebel-sur-Quévillon, reducing the need for a large construction and operations camp at Windfall Lake, as well as a reduced rotational work force;
• cost savings on transportation and construction/operations logistics from existing rail and road access to Lebel-sur-Quévillon, which is expected to offset the cost of transportation of mineralized material from the mine over the existing 103 kilometres of road networks;  and
• the location of the Site positively affecting the economics of gold deposits within trucking distance of Lebel-sur-Quévillon.   

John Burzynski, President and CEO of Osisko commented:  “Identifying this site near Lebel-sur-Quévillon dynamically changes the way we are evaluating the potential infrastructure for Windfall, including the mill complex, personnel accommodations, administration buildings and tailings management facility.  Lebel-sur-Quévillon appears to have many strong advantages over Windfall and we believe the potential savings to both capex and opex would be significant.” 

The Corporation is currently evaluating the Windfall Lake gold project as a potential underground mining operation.  Osisko is well-funded with approximately $190 million in cash and equity investments, and is carrying out an intensive definition drilling and large-scale exploration campaign on Windfall and the surrounding area.  An updated NI 43-101 resource estimate on the Windfall Lake project is planned for release in the second half of 2017.  Osisko has commenced collection of environmental baseline data in the vicinity of Windfall and intends to collect additional data along the potential haul road and around the proposed Site.

The Quévillon exploration property acquisitions and agreement recently announced (see Osisko press releases dated March 6, 2017 and March 15, 2017) include approximately thirty known gold showings as well as the Osborne-Bell gold deposit, which is located 32 kilometres northwest of the proposed Site. The Osborne-Bell deposit has been the object of significant historical drilling over the past fifteen years, and will be the focus of new drilling and resource re-evaluation by Osisko in 2017.

Mr. Burzynski continued:  “Over the past 14 years, the Osisko team has always been innovative.  The world-class Canadian Malartic mine was discovered, defined, financed, built and put in production, from first drill hole to first gold pour, in a little over six years, a remarkable achievement for our team.  We are highly encouraged by the potential at Windfall and the potential of the region.  With the possibility of centralizing a new milling complex at Lebel-sur-Quévillon, we believe we may be opening up the region to a new generation of Québec mines, and at the same time securing Osiskos position as a new Canadian intermediate mining house.”

(Montréal, March 27, 2017) – Osisko Mining Inc. (TSX:OSK, “Osisko” or the “Corporation“) is pleased to announce it has received confirmation from the Québec Ministère du Développement durable, de lEnvironnement et de la Lutte contre les changements climatiques (“MDDELCC“) of the transfer of the existing certificate of authorization (CA) from a previous operator to Osisko for the purpose of extracting a bulk sample.

An underground exploration ramp was commenced at the Windfall deposit from surface in 2007 by a previous operator, eventually attained a vertical depth of approximately 110 metres and length of approximately 1.2 kilometres, with an additional 230 metres of exploration drifts.  The exploration ramp was terminated prior to completion and was allowed to refill with water.

Pending approval of the water treatment system from MDDELCC, dewatering of the ramp will begin in the second quarter of 2017.

About the Windfall Lake Gold Deposit
The Windfall Lake gold deposit is located between Val-dOr and Chibougamau in the Abitibi region of Québec, Canada. The current mineral resource comprises 2,762,000 tonnes at 8.42 g/t Au (748,000 ounces) in the indicated category and 3,512,000 tonnes at 7.62 g/t Au (860,000 ounces) in the inferred category (sourced from a technical report dated June 10, 2015 entitled “Preliminary Economic Assessment of the Windfall Lake Gold Property, Québec, Canada” with an effective date of April 28, 2015, prepared in accordance with NI 43-101). The Windfall Lake gold deposit is currently one of the highest grade resource-stage gold projects in Canada. The bulk of the mineralization occurs in the Main Zone, a southwest/northeast trending zone of stacked mineralized lenses, measuring approximately 600 metres wide and at least 1,400 metres long. The deposit is well defined from surface to a depth of 500 metres, and remains open along strike and at depth. Mineralization has been identified only 30 metres from surface in some areas and as deep as 870 metres in others, with significant potential to extend mineralization up and down-plunge and at depth.

About the Kan Property

The Kan Property is located in the Nunavik Territory in northern Québec.  The property is a large gold and base-metal exploration project covering a surface area of over 30,000 hectares in the Labrador Trough, 85 kilometres southwest of Kuujjuaq.  A silicate-carbonate iron formation of regional extent represents a significant auriferous unit on the property sharing similarities with the world-class Homestake gold deposit.  Historical work conducted in the 1990’s led to the discovery of numerous gold showings within the iron formation, with drill results returning 5.1 g/t Au over 6 metres (Ferricrete Showing) and 9.46 g/t Au over 2 metres (Kan Showing).  Work carried out by Rio Silver Inc. in 2011-2012 yielded 3.12 g/t Au over 13.9 metres in channels and 1.2 g/t Au over 10.4 metres in drilling on the Pump Pad Ridge showing.  Exploration work performed in 2014-2016 by Virginia Mines Inc. (subsequently Osisko Exploration James Bay) led to the discovery of additional gold mineralization associated with the silicate-carbonate iron formation on the Kan Property.  Best results from this work include values of:  8.1 g/t Au over 7 metres (Pump Pad Ridge showing); 10.7 g/t Au over 5 metres (Winchester showing); and 8.6 g/t Au over 3.2 metres (KTR showing) obtained from channels; and values of 2.13 g/t Au over 8 metres and 4.62 g/t over 8 metres obtained from drilling (Winchester-Pump-Pad Ridge).
