(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.

3.22 g/t Au Over 11.6 Metres Located 3.7 Kilometres West of Windfall Deposit

(Montréal, August 29, 2016).  Osisko Mining Inc. (OSK:TSX, “Osisko” or the “Corporation”) is pleased to announce a new discovery from the ongoing exploration drill program on its 100% owned Urban-Barry Project located in Urban Township, Québec. The exploration drill program currently involves one drill and is part of the ongoing 100,000 metre drill program at Osisko’s Windfall Lake gold project.

The discovery was made in DDH OSX-W-16-717, which returned an average of 3.22 g/t Au over 11.6 metres.  DDH OSX-W-16-717 is located approximately 3.7 kilometres west – northwest of the main Windfall deposit, and lies approximately 1.4 kilometres northwest of exploration hole OBX-16-666 (183.5 g/t Au over 0.3 metres, see Osisko press release dated June 3, 2016).  DDH OSX-W-16-717 is part of a fence of holes currently testing the westerly strike of the Windfall Deposit geological trend.  A number of target styles are being investigated along this fence, including geophysical anomalies and as follow-up to earlier identified gold-in-till anomalies.

The new drill hole underscores the strong potential for new gold mineralization on the Urban-Barry Project, which has historically seen limited exploration work.  The table below details results from the new hole:

OSX-W-16-717 targeted the contact between a magnetic high and low, 3.7 km to the WNW of the Main Zone at Windfall. The gold mineralization occurs within a zone of strong texturally-destructive sericite and silica alteration in andesite volcanics containing 2-3% pyrite stringers, with tourmaline, fine grained pyrite disseminations and zones of silica-filled brecciated stringers cross-cutting the interval.  The mineralization is very similar to that seen at the nearby Windfall gold deposit.

Definition drilling near the Caribou Zone has led to a significant new discovery 150 metres below the known Caribou Zone.  The new mineralized zone (“Wolf Zone”) is defined by drill hole OSK-W-16-710 which intersected 11.8 g/t Au over 6.7 metres  (23.62 g/t Au over 6.7 metres uncut) from 562.0m – 568.9m.  Additional mineralization was also discovered in the hanging wall and footwall of the Wolf Zone, with assays returning 8.32 g/t over 3.0 metres and 16.2 g/t Au over 2.3 metres respectively.  Further drilling will be directed to investigating the dimensions of the Wolf Zone in the coming month.  These new intercepts demonstrate the high potential for significant new mineralization near the known Windfall mineral inventory through continued definition and exploratory drilling.

Highlights from additional new drill holes also include: 8.89 g/t Au over 6.9 metres in DDH OBM 16-701, 18.4 g/t Au over 2.3 metres in DDH OBM-16-703, 16.2 g/t Au over 2.3 metres in DDH OSK-W-16-710, 16.0 g/t Au over 2.0 metres in DDH OBM-16-697; 11.33 g/t Au over 2.2 metres in DDH OSK-W-16-707, and 8.06 g/t Au over 2.5 metres in DDH OBM-16-698. The new results continue to demonstrate lateral and vertical continuity of high grade gold mineralization in Zone 27 and the Caribou Zone, and also highlight new zones developing between those two major mineralized corridors.  Details of the significant new results are outlined in the table below:

Drill Hole Collar Coordinates and Information:

DDH OBM-16-697 intersected 16.0 g/t Au over 2.0 metres, including 63.5 g/t Au over 0.5 metres in a quartz-tourmaline vein at the contact between a porphyry dyke and felsic volcanics.

DDH OBM-16-698 intersected 8.06 g/t Au over 2.5 metres, including 19.0 g/t Au over 1.0 metre at the upper contact of a porphyry dyke. This interval is located 140 metres to the SE of the Caribou Zone in a sparsely drilled sector.  The hanging wall of the Caribou Zone returned 3.62 g/t Au over 2.9 metres.  This hole also intersected gold mineralization in the eastern extension of the Caribou N2 Zone 110 metres further east than the known zone, returning 4.49 g/t Au over 3.5 metres.

DDH OBM-16-699 discovered new gold mineralization 90 metres to the NW of the FW3 Zone (below Red Dog) returning 6.63 g/t Au over 2.5 metres (including 21.6 g/t Au over 0.5 metres).  Further drilling will follow up in this sparsely drill sector.

DDH OBM-16-701 is located 140 metres to the ENE of the previously interpreted Caribou Zone.  The hole intersected a new zone to the SW of Caribou, returning 5.14 g/t Au over 6.1 metres.  This hole also intersected the Caribou hanging wall, returning 4.82 g/t Au over 7.0 metres (including 22.4 g/t Au over 1.0 metre) in an altered andesite with a crustiform vein.  The hole also intersected the eastern extension of the Caribou N2 zone, returning 8.86 g/t Au over 6.9 metres (including 47.7 g/t Au over 1.0 metre). The hole also intersected 6.68 g/t Au over 2.1 metres at the contact of a porphyry dyke in the eastern extension of Zone 27.

DDH OBM-16-702 tested the shallow portion of the Caribou Zone and returned 3.81 g/t Au over 1.8 metres (including 9.69 g/t Au over 0.7 metres).

DDH OBM-16-703 intersected the interpreted western extension of the FW1 Zone (below Red Dog) and returned 18.4 g/t Au over 2.3 metres (including 38.23 g/t Au over 1.1 m) in a felsic volcanic rock containing pyrite and traces of chalcopyrite.

DDH OBM-16-704 intersected Zone 27 returning 3.55 g/t Au over 4.2 metres.  This intercept is located 33 metres below OBM-16-685 (which returned 9.63 g/t Au over 3.3 metres) and confirms continuity of gold mineralization in this zone.

DDH OSK-W-16-705 intersected the new Wolf Zone (also intersected in DDH OSK-W-16-710), returning 4.04 g/t Au over 2.0 metres in an altered mafic volcanic rock.

DDH OSK-W-16-707 intersected the Caribou S2 Zone 190 metres below surface, returning 11.33 g/t Au over 2.2 metres (including 58.6 g/t Au over 0.4 metres) in a porphyry dyke.

DDH OSK-W-16-709 intersected the extension of the Caribou S1 Zone, returning 4.90 g/t Au over 3.7 metres in a sparsely drilled sector.

DDH OSK-W-16-710 confirmed the new Wolf Zone, returning 11.8 g/t Au over 6.7 metres.  The Wolf Zone is located between the Caribou S3 and the Caribou N2 Zones.  The Wolf Zone correlates with OBM-16-658 which returned 8.90 g/t Au over 8.0 metres, now re-interpreted to be part of this new zone.  Additional new mineralization was also discovered in the hanging wall and footwall of the Wolf Zone, returning 8.32 g/t over 3.0 metres and 16.2 g/t Au over 2.3 metres respectively.  The Wolf Zone remains undefined by drilling to the east.

Full analytical results from the 12 new drill holes are available at www.osiskomining.com.

OBM-16-700 was abandoned due to drilling conditions, and assay results for drill holes OSK-W-16-706 and OSK-W-16-708 are pending.

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”).

Quality Control
True widths of the new exploration intercepts reported in this press release have yet to be determined. 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 kg 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 kg 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 analysed 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 QA/QC program consistent with NI 43-101 and industry best practices. Standards and blanks are included with every 20 samples for QA/QC purposes by the Corporation as well as the lab. Approximately 5% of sample pulps are sent to secondary laboratories for check assays.

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, Quebec, 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.

(Montréal, August 16, 2016).  Osisko Mining Inc. (OSK:TSX, “Osisko Mining” or the “Corporation”) is pleased to announce that it has entered into a letter of agreement with Osisko Gold Royalties Ltd. (“Osisko Royalties”) to earn 100% of its interest in its portfolio of exploration properties held in the James Bay and Labrador Trough areas of Québec.  Under terms of the agreement (the “Agreement”), the highly regarded Québec based exploration portfolio will be optioned to Osisko Mining in return for time-based exploration expenditures.  Osisko Mining will benefit from the years of expertise brought to bear on these projects by the former Virginia Mines Inc. exploration team (acquired by Osisko Royalties in 2015), and will continue to advance significant exploration programs by integrating this team into Osisko Mining.

Osisko Mining may earn 50% interest of Osisko Royalties interest upon incurring expenditures totaling $19.2 million, and a 100% of its interest upon completing the total investment of $32 million over a 7 year period.  Osisko Royalties will maintain an escalating royalty ranging from 1% to a maximum of 3.5% on the properties subject to certain conditions in the Agreement to be negotiated between the parties prior to completion of the transaction.  New properties acquired by Osisko Mining in the designated area of interest during a 7 year term will also be subject to the Agreement.  Osisko Royalties will undertake not to participate in any exploration activities and will be required not to compete with Osisko Mining in areas covered by the Agreement, except for the continuation of activities on its Coulon copper-zinc project held by Osisko Royalties and other Québec institutional shareholders.

John Burzynski, Chief Executive Officer and President of Osisko Mining commented:  “We are very pleased to be able to announce today’s agreement with Osisko Gold Royalties.  Under the Agreement, Osisko Mining has the option to acquire 100% of Osisko Royalties interests in its James Bay portfolio, a group of 32 projects covering over 447,000 hectares in Quebec’s prolific James Bay area, in return for a seven year exploration commitment.  This property portfolio was developed over years of work conducted by the Osisko James Bay exploration group (formerly the Virginia Mines exploration group), and as part of the agreement Osisko Mining will be bringing the Osisko James Bay Exploration team into our company.  The transaction involves no share dilution or cash payments from Osisko Mining, and provides a vast territory of exploration ground to compliment Osisko Mining’s ongoing drilling programs at our major deposits in Québec and Ontario.  Significantly, Osisko Mining will also acquire the historic Virginia Mines database that was built up over more than 20 years with highly successful exploration in the James Bay and Labrador Trough areas.  The Osisko group, through the former Osisko Mining Corporation and former Virginia Mines teams, has had a great history of discovering gold at the drill bit, including two significant discoveries that are now both Quebec’s newest and largest gold mines – Canadian Malartic and Eleonore.  It is our hope and expectation that today’s announced transaction will provide further opportunities for Osisko Mining to make significant new discoveries in Québec.”

Completion of this transaction is subject to the negotiation and execution of definitive documentation, and obtaining any regulatory approvals, including TSX approval. The transaction is expected to have an effective date of October 1, 2016.

Due to the fact that Osisko Royalties is an insider of and a related party of Osisko Mining, this transaction is considered 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 intends to rely on the exemption from the valuation requirements of MI 61-101 contained in section 5.5(a) and from minority approval requirements pursuant to section 5.7(a), due to the fact that 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

In connection with completion of the transactions described here, Osisko Mining understands that Osisko Royalties intends to exercise its option (negotiated on June 30, 2015) on properties held by Osisko Mining as of August 25, 2015, by paying $5 million.  Under terms of this agreement, Osisko Royalties will receive a 1% royalty on Osisko Mining’s Windfall property and Urban Barry property package in return for a cash payment of $5 million, in addition to its original equity investment of $17.8 million in August 2015.

Cautionary Statements Regarding Technical Information

Mineral resources are not mineral reserves and do not have demonstrated economic viability. The estimate of mineral resources may be materially affected by environmental, permitting, legal, title, socio-political, marketing or other relevant issues. In particular, the quantity and grade of reported inferred mineral resources in the estimates referenced in this press release are uncertain in nature and there is insufficient exploration to define these inferred mineral resources as an indicated or measured mineral resource in all cases. It is uncertain in all cases whether further exploration will result in upgrading the inferred mineral resources to an indicated or measured mineral resource category.
