(Montréal, December 19, 2016).  Osisko Mining Inc. (OSK:TSX, “Osisko” or the “Corporation”) is pleased to announce that it is increasing the scale of the ongoing drill program at its 100% owned Windfall Lake gold project located in the Urban Township, Québec. 

Since late October 2015, Osisko has drilled approximately 115,000 metres as part of an originally announced 50,000 metre program (expanded twice to the current 150,000 metre drilling campaign) on the Windfall Lake gold deposit and surrounding exploration targets in Urban and Barry Townships.  Exploration success in the initial 150,000 metre program has included:

• An upgraded geological interpretation of the Windfall deposit which is leading to a significantly expanded and still growing footprint for the previously known area of mineralization;

• the discovery of several significant new zones of mineralization (including Wolf Zone and the recently announced new shallow high-grade zone (known as the Lynx Zone) discovered on the 600 metre extension fence);

• the recently announced 600 metre NE extension of the main corridors of mineralization (Caribou, Zone 27, Wolf and Underdog); and

• two new discoveries in the surrounding area (Fox and Black Dog).

Additional drills have also recently commenced regional exploration on a bank of exploration targets developed from grass-roots exploration over the past year.

The new 250,000 metres of drilling will assist the Corporation in further exploring and defining the known mineralization within the main deposit area and the recently discovered NE extension area.  The Corporations objective is to maximize the level of information to be included in an anticipated initial 2017 resource update.

Osisko continues to work towards permitting for extension of the ramp into the Windfall deposit, with a view to starting underground exploration development in the second half of 2017.

The Windfall Camp expansion has also been recently completed, with new accommodations, core logging areas and other facilities for the approximately 100 people currently working at site.

Osisko recently completed a $14 million financing directed to the ongoing programs at Windfall.  The Corporation is well financed and currently has over $90 million in cash and over $40 million in marketable securities.

Qualified Person

The scientific and technical content of this press release has been reviewed, prepared and approved by Mr. Jean-Philippe Desrochers, Ph.D., P.Geo. Senior Project Manager of the Windfall Lake gold project, who is a “Qualified Person” as defined by National Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI 43-101”).

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 National Instrument 43-101 – Standards of Disclosure for Mineral Projects). 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.

(Montréal, December 6, 2016).  Osisko Mining Inc. (OSK:TSX, “Osisko” or the “Corporation”) is pleased to announce initial drill results from its 100% owned Black Dog gold project located in Barry Township, Québec.  The project is situated 15 kilometres SW of its flagship Windfall Lake Gold Deposit.  Drilling is targeting geophysical conductors identified with an airborne electromagnetic (EM) survey completed earlier in the year by Osisko that coincide with a 600 x 800 metre circular magnetic anomaly. The geophysical anomalies sit atop a zone of pervasive and/or brecciated quartz-tourmaline-sulfide alteration that has been the object of historical shallow drilling.

DDH OSK-BD-16-002 was collared 150 metres to the east of an outcropping alteration zone (dubbed “Tourmaline Hill”).  This new hole intersected 6.14 g/t Au and 34.1 g/t Ag over 14.4 metres, including 15.6 g/t Au and 93.5 g/t Ag over 2.8 metres in a mineralized tourmaline breccia containing 2-15% coarse pyrite and 10% chalcopyrite.  This intersection is part of a wider intercept that averaged 3.42 g/t Au and 23.2 g/t Ag over the entire intersected length of 32.1 metres.  Significant results from the two drill holes are presented in the table below.  DDH OSK-BD-16-001 was collared 600 metres to the SW of OSK-BD-16-002 and intersected 5.76 g/t Au and 34.8 g/t Ag over 0.9 metres in a tourmaline breccia. 

Further drilling is currently in progress and is directed at determining the extent and continuity of the new mineralization discovered at Black Dog.

Maps and sections showing the location of DDH OSK-BD-16-001 and -002 are available at www.osiskomining.com. 
 

Notes:

1. For complete drilling results please see www.osiskomining.com.
2. True Widths are not known.  See “Quality Control” below.

Full analytical results from the new drill holes are available at www.osiskomining.com.

Qualified Person
The scientific and technical content of this news release has been reviewed, prepared and approved by Mr. Jean-Philippe Desrochers, Ph.D., P.Geo. Senior Project Manager of the Windfall Lake gold project and the Black Dog Gold Project, who is a “Qualified Person” as defined by National Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI 43-101”).

Quality Control
Additional drilling is planned for the immediate area which will enable the true width determination.  Assays are uncut except where indicated. All NQ core assays reported were obtained by either 1 kilogram whole rock metallic screen/fire assay or standard 50 gram fire-assaying with AA or gravimetric finish at ALS Laboratories in Val dOr, Québec or Sudbury, Ontario. The 1 kilogram metallic screen assay method is selected by the geologist when samples contain coarse gold or present a higher percentage of pyrite than surrounding intervals. All samples are also analyzed for multi-elements, including silver, using an Aqua Regia-ICP-AES method at ALS laboratories. Drill program design, Quality Assurance/Quality Control and interpretation of results is performed by qualified persons employing a Quality Assurance/Quality Control program consistent with NI 43-101 and industry best practices. Standards and blanks are included with every 20 samples for Quality Assurance/Quality Control purposes by the Corporation as well as the lab. Approximately 5% of sample pulps are sent to secondary laboratories for check assays.

About the Black Dog Project
The Black Dog Project is located approximately 90 kilometres east of Lebel sur Quevillon, 14 kilometres southwest of, and along the same geological trend as, Osiskos Windfall Lake project. Three zones have been defined by historical work on the property including the Nubar Zone (with estimated resources of 564,000 tonnes at 6.2 g/t Au, based on historical estimates that have not been prepared in accordance with NI 43-101, the Tourmaline Hill Zone, and the Barry-Souart Zone. These three zones are located along a 5 kilometre length of the same geological structure. See below under the heading “Disclosure of Historical Estimates”.

Disclosure of Historical Estimates
In 1950, Nubar Mines Ltd. sunk a 44 metre deep shaft and drove 135 metres of drifts and crosscuts.  Several exploration surveys were then completed by other companies (Glenelm Developers Limited, Goldmaster Mines Ltd., Shell Canada Limited, Tut Explorations, Société de développement de la Baie-Jaimes (SDBG) and Oasis Resources Inc.). Between 1985 and 1990, Oasis Resources Inc. completed 152 drill holes, followed with an estimated resource calculation of 564,000 tonnes at 6.2 g/t Au. These resource estimates are of a historical nature and do not comply with NI 43-101. However, the resource estimate may be relevant because the Black Dog property encompasses the same geological trend that the Nubar Zone occupies and, to the best of the knowledge of Mr. Jean-Phillipe Desrochers, there has been no material change with respect to the metallic minerals within the original resource estimation area (and region) that would affect the estimation parameters since 1985. Further drilling would be required to upgrade or verity the historical resource estimate as current mineral resources or reserves. Osisko is unaware of the existence of any technical report prepared in connection with the scientific and technical information in this news release. A Qualified Person (within the meaning of NI 43-101) has not done sufficient work to classify the historical estimate as current mineral resources or mineral reserves. Osisko is not treating the historical estimate as current mineral resources or mineral reserves. Further, there have not been any mineral resources calculated on the Black Dog property recently.

(Montréal, October 5, 2016)  Osisko Mining Inc. (OSK:TSX, “Osisko Mining” or the “Corporation”) is pleased to announce that it has finalized the earn-in transaction with Osisko Gold Royalties Ltd (“Osisko Royalties”), as announced by the Corporation on August 16, 2016. Under the terms of the earn-in agreement, Osisko Mining may earn a 100% interest in Osisko Royalties’ interest in 28 exploration properties located in the James Bay area, Québec and the Labrador Trough area (the “Properties”) upon incurring exploration expenditures totaling $32 million over the 7year term of the earn-in agreement; Osisko Mining will earn a 50% interest upon completing expenditures totaling $19.2 million.  Osisko Royalties will retain an escalating net smelter return (“NSR”) royalty ranging from 1.5% to a maximum of 3.5% on precious metals and a 2% NSR royalty on other metals and minerals produced from the Properties.  Additionally, any new properties acquired by Osisko Mining in the designated area during the 7-year term of the earn-in agreement may also be subject to a royalty agreement in favour of Osisko Royalties with similar terms and subject to certain conditions.  In connection with the transaction, Osisko Royalties has covenanted not to participate in any exploration activities and not to compete with Osisko Mining in the areas covered by the earn-in agreement; provided, however, that Osisko Royalties may continue its existing activities in respect of the Coulon copper-zinc project held by Osisko Royalties and other Québec institutional shareholders and on four other exploration properties.

As part of the transaction, Osisko Mining is hiring all of the existing Québec based exploration team of Osisko Royalties (being the former employees of Virginia Mines Inc.).

John Burzynski, President and Chief Executive Officer of Osisko Mining stated: “We are very pleased to complete this earn-in agreement with Osisko Royalties.  The property portfolio in the James Bay region of Québec compliments our expanding programs at Windfall, and with both project groups being in the same geographical area of Québec and falling within the boundaries of Québecs Plan Nord program, we expect to see logistical and project execution efficiencies.  We are looking forward to having the ex-Virginia team join our group in the pursuit of new discoveries in the Windfall camp, and continuing their work on the James Bay area projects.”

Due to the fact that Osisko Royalties is an insider of and a related party of Osisko Mining, this transaction is a “related party transaction” as set out in Multilateral Instrument 61-101 ‒ Protection of Minority Security Holders in Special Transactions (“MI 61-101”). Osisko Mining has relied on the exemption from the valuation requirements of MI 61-101 contained in section 5.5(a) and from minority approval requirements under section 5.7(a), because the fair market value of the subject matter of, and the consideration for, the transaction, does not exceed 25% of the market capitalization of Osisko Mining. The entry into of the transaction has been approved by the directors of Osisko Mining, other than those with an interest in Osisko Royalties.

Exercise of Option

Osisko Royalties has also exercised its option to acquire 1% NSR royalty on Osisko Minings Windfall and Urban Barry properties for $5 million.  Osisko Mining is currently executing a 150,000 metre program on the Windfall Project and surrounding area.

(Montréal, September 29, 2016) Osisko Mining Inc. (OSK:TSX, “Osisko”) is pleased to announce that it has commenced a 15,000 metre drill program on its 100% owned Black Dog property (formerly known as the “Souart” property) situated 14 kilometres southwest of the Windfall deposit.

The drill program has been designed to test targets along the five kilometre of strike of the main structure hosting the historical Nubar showing, to investigate gold anomalies associated with the Tourmaline Hill Zone, and to expand the Barry-Souart Zone.

About the Black Dog Property
The Black Dog property was acquired by Osisko in February 2016 (as further described in the press release of Osisko dated February 3, 2016). The property is located 90 kilometres east of the town of Lebel-sur-Quevillon, Québec on the Barry-Urban greenstone belt and lies 14 kilometres southwest from the Windfall Lake gold deposit.  Black Dog hosts three known zones of mineralisation over a strike length of five kilometres:  the Nubar Zone;  Tourmaline Hill Zone;  and the Barry-Souart Zone. The Nubar Zone has estimated resources of 564,000 tonnes at 6.2 g/t Au based on historical estimates that have not been prepared in accordance with National Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI 43-101”). Please see “Disclosure of Historical Estimates” below.

Disclosure of Historical Estimates
In 1950, Nubar Mines Ltd. sunk a 44 metre deep shaft and drove 135 metres of drifts and crosscuts. Several exploration surveys were then completed by a number of other companies (Glenelm Developers Limited, Goldmaster Mines Ltd., Shell Canada Limited, Tut Explorations, Société de développement de la Baie-James (SDBG) and Oasis Resources Inc.).  Between 1985 and 1990, Oasis Resources Inc. completed 152 drill holes, followed with an estimated resource calculation of 564,000 tonnes at 6.2 g/t Au. This resource estimate is of a historical nature and does not comply with NI 43-101. However, the resource estimate may be relevant because the Souart property forms part of the same geological trend encompassed by the Nubar Zone and, to the best of the knowledge of Mr. Jean Philippe Desrochers, Qualified Person, there has been no material change with respect to the metallic minerals within the original resource estimation area (and region) that would affect the estimation parameters since 1985.  Further drilling would be required to upgrade or verify the historical resource estimate as current mineral resources or reserves.  Osisko is unaware of the existence of any technical report prepared in connection with the scientific and technical information in this news release. A Qualified Person (within the meaning of NI 43-101) has not done sufficient work to classify the historical estimate as current mineral resources or mineral reserves. Osisko is not treating the historical estimate as current mineral resources or mineral reserves. Further, there have not been any mineral resources calculated on the Souart property recently.
