 Acquisition of a precious metals portfolio of assets from Orion Mine Finance Group (“Orion”) for $1.1 billion

consisting of 74 royalties, streams and precio us metal offtakes, including a 9.6% diamond stream on the Renard

diamond mine and a 4% gold and silver stream on the Brucejack gold and silver mine, both of which are new mines

in Canada, in addition to a 100% silver stream on the Mantos Blancos copper mine in Chile;

 Declaration of quarterly dividends totalling $0.18 per common share for 2017.

1 GEOs are calculated on a quarterly basis and include royalties, streams and offtakes. Silver earned from royalty and stream ag reements was converted to gold

equivalent ounces by multiplying the silver ounces by the average silver price for the period and di viding by the average gold price for the period. Diamonds, other

metals and cash royalties were converted into gold equivalent ounces by dividing the associated revenue by the average gold p rice for the period. Offtake agreements

were converted using the f inancial settlement equivalent divided by the average gold price for the period. Refer to the portfolio of royalty, stream and other interests

section for average metal prices used.

2 “Adjusted earnings” and “Adjusted earnings per basic share” are non-IFRS financial performance measures which have no standard definition under IFRS. Refer to the

non-IFRS performance measures section of this press release.

3 The cash cost of an investment is a n on-IFRS measure representing the cash paid on the acquisit ion of an investment. The gain or the loss is calculated by subtracting

the cash acquisition cost from the cash proceeds on the sale of an investment.

Acquisition of Orion’s Portfolio

On July 31, 2017, Osisko acquired a precious metals portfolio of assets from Orion consisting of 61 royalties, 6 streams and

7 precious metal offtakes for $1.1 billion. The final acquisition price was comprised of US$504.8 million ($630.1 million) in

cash consideration, which includes a US$4.2 million ($5.1 million) adjustment for the ac quired working capital, and

30,906,594 common shares of Osisko issued to Orion (the “Purchase Price”) (the “Transaction”). Any sale of the shares

issued to Orion is subject to certain restrictions, including a 12-month hold period and a broad distribution requirement.

The combination of Osisko and Orion’s portfolios resulted in Osisko holding a total of 131 royalties, streams and offtakes,

including 16 revenue-generating assets on July 31, 2017. Through the Transaction, the Company acquired a 9.6% diamond

stream on the Renard diamond mine and a 4% gold and silver stream on the Brucejack gold and silver mine, both of which

are new mines in Canada, in addition to a 100% silver stream on the Mantos Blancos copper mine in Chile. Certain assets

are held through an international wholly -owned subsidiary which was renamed Osisko Bermuda Limited (“OBL”). The

Brucejack stream is subject to certain buyback rights held by Pretium Resources Inc. which could result in the stream being

repurchased on December 31, 2018 and other specific dates.

As part of the Transaction, CDP Investissements Inc., an affiliate of Caisse de dépôt et placement du Québec (“Caisse”) and

the Fonds de solidarité des travailleurs du Québec (F.T.Q.) (“Fonds F.T.Q.”) subscribed for $200 million and $75 million in

common shares of Osisko, respectively, as part of a concurrent private placement (“Private Placement”) to fund a portion of

the cash consideration and support the Transaction. A total of 18,887,363 common shares were issued at a price of $1 4.56

per share under the Private Placement. The Private Placement was subject to a 7% capital commitment payment payable

partially in shares (2% representing 385,457 common shares) and in cash (5% representing $13.8 million).

Following the Transaction, Or ion, Caisse and its affiliates and Fonds F.T.Q. held respectively approximately 19.7%, 12.1%

and 5.5% of Osisko’s issued and outstanding common shares, based on the number of common shares of Osisko

outstanding at the closing of the Transaction on July 31, 2017.

Osisko also drew US$118 million ($147.3 million) under its revolving credit facility with the National Bank of Canada and

Bank of Montreal, settled the foreign exchange forward contracts by disbursing $275 million to acquire US$204.0 million and

paid US$182.8 million ($228.9 million) from Osisko’s then current cash and cash equivalents balance.

The transaction has been recorded as a business combination with Osisko as the acquirer. The assets acquired and the

liabilities assumed were recorded at t heir estimated fair market values at the time of the closing of the acquisition, being

July 31, 2017. The transaction costs related to the acquisition were expensed under business development expenses and

amounted to $8.9 million.

Acquisition of Back-Forty Gold Stream

The Back Forty project is a zinc and gold volcanogenic massive sulfide deposit located in Michigan, United States, owned by

Aquila Resources Inc. (“Aquila”). The Back Forty project is in the development stage an d advancing toward a feasibility study

expected in 2018. Back Forty is expected to produce 532,000 ounces of gold, 721 million pounds (“lbs”) of zinc, 74 million lbs

of copper, 4.6 million ounces of silver, and 21 million lbs of lead. The details of the mi neral inventory can be found under

Aquila’s profile on SEDAR at www.sedar.com. Through the acquisition of Orion’s Portfolio, Osisko acquired t he Back Forty

silver stream, which applies to 75% of payable silver productio n over the mine’s operating life and includes ongoing transfer

payments by OBL to Aquila of US$4.00 per ounce of refined silver delivered under the stream.

In November 2017, OBL acquired an additional gold stream on the Back Forty project. OBL will make s taged upfront cash

deposits to Aquila of up to US$55 million for the gold stream, and will make ongoing payments equal to 30% of the spot price

of gold, to a maximum of US$600 per ounce. The gold stream applies to 18.5% of the refined gold from the project until

105,000 ounces of gold have been delivered, and to 9.25% of the refined gold for the remaining life-of-mine.

The deposit will be paid in four installments, as follows:

1. US$7.5 million was paid on closing of the gold stream transaction;

2. US$7.5 million payable upon receipt by Aquila of all material permits required for the development and operation of

the project, and receipt of a positive feasibility study;

3. US$10 million payable following a positive construction decision for the property; and

4. US$30 million payable upon the first drawdown of an appropriate project debt finance facility, subject to the change

of control provision. In the event of a change of control of Aquila prior to the advancement of the fourth deposit, the

person or entity acquiri ng control over the project may elect to forego the fourth deposit, in which case the stream

will be reduced to 9.5% of the refined gold from the project until 105,000 ounces of gold have been delivered and to

4.75% of the refined gold for the remaining life-of-mine. All other terms and conditions will remain unchanged.

Gibraltar Stream (Taseko Mines Limited)

On March 3, 2017, Osisko closed the acquisition of a silver stream with reference to silver produced at the Gibraltar copper

mine (“Gibraltar”), lo cated in British Columbia, Canada from Gibraltar Mines Ltd. (“Gibco”), a wholly -owned subsidiary of

Taseko having a 75% interest in Gibraltar. Osisko paid Taseko cash consideration of US$33.0 million ($44.3 million) to

purchase a silver stream and 3.0 mill ion warrants of Taseko. Each warrant allows Osisko to acquire one common share of

Taseko at a price of $2.74 until April 1, 2020. The fair value of the warrants was evaluated at $1,780,000 using the Black -

Scholes option pricing model and the residual value of $42,678,000 was attributed to the silver stream (including $175,000 of

transaction fees). With regards to the silver stream, Osisko will make ongoing payments of US$2.75 per ounce of silver

delivered.

Under the stream, Osisko will receive from Taseko an amount equal to 100% of Gibco’s share of silver production until the

delivery to Osisko of 5.9 million ounces of silver to Osisko and 35% of Gibco’s share of silver production thereafter. Gibral tar

is the second largest open pit copper mine in Canada an d fourth largest in North America. The life of mine yearly average

production from Gibraltar is approximately 140 million lbs of copper and 2.6 million lbs of molybdenum. With a large mineral

reserve of 3.2 billion lbs of recoverable copper and 58 million lbs of molybdenum, the estimated mine life of the project is 23

years (proven and probable mineral reserves as of January 1, 2016). The acquisition is expected to increase Osisko’s

production by approximately 200,000 ounces of silver for the next 14 years, increasing to an average of 350,000 ounces of

silver for the remainder of the 23 -year mineral reserve life of Gibraltar. Any silver in respect of which a delivery was made

after January 1, 2017, was subject to the stream.

Revolving Credit Facility

In November 2017, the Company amended its revolving credit facility (the “Facility”) increasing the amount from $150 million

to $350 million, with an additional uncommitted accordion of up to $100 million, for a total availability of up to $450 milli on.

The accordion is subject to standard due diligence procedures and acceptance of the lenders. The Facility is to be used for

general corporate purposes and investments in the mineral industry, including the acquisition of royalties, streams and other

interests. The Facility is secured by the Company’s assets (including the royalty, stream and other interests) and has a four -

year term (November 14, 2021), which can be extended by one year on each of the first two anniversary dates.

The Facility is subject to standb y fees. Funds drawn will bear interest based on the base rate, prime rate or London Inter -

Bank Offer Rate (“LIBOR”) plus an applicable margin depending on the Company’s leverage ratio. On July 31, 2017, the

Facility was drawn for US$118.0 million (represen ting $148.0 million as at December 31, 2017) to fund the acquisition of

Orion’s Portfolio. As at December 31, 2017, the interest rate was 2.96%, including the applicable margin. The Facility

includes covenants that require the Company to maintain certain financial ratios and meet certain non-financial requirements.

As at December 31, 2017, all such ratios and requirements were met.

Bought Deal of Convertible Senior Unsecured Debentures

On November 3, 2017, Osisko closed a bought deal offering of convertibl e senior unsecured debentures (the “Debentures”)

for $300 million (the “Offering”) with a syndicate of underwriters co -led by National Bank Financial Inc., BMO Capital Markets

and Desjardins Capital Markets (the “Underwriters“). The Offering was comprised of a $184.0 million public offering of

Debentures (the “Public Offering“) and a $116.0 million private placement of Debentures (the “Private Offering“). In

connection with the Offering, the Public Sector Pension Investment Board and Ressources Québec inc., a wholly -owned

subsidiary of Investissement Québec, purchased respectively $100.0 million and $16.0 million of Debentures through the

Private Offering on the same terms and conditions as the Public Offering. The Underwriters have received a commission of

3.55% in relation to the Offering. Net proceeds amounted to $288.5 million.

The Debentures bear interest at a rate of 4.0% per annum, payable semi -annually on June 30 and December 31 of each

year, commencing on June 30, 2018. The Debentures are convertibl e at the holder’s option into Osisko common shares at a

conversion price of $22.89 per common share. The Debentures will mature on December 31, 2022 and may be redeemed by

Osisko, in certain circumstances, on or after December 31, 2020. The Debentures are listed for trading on the Toronto Stock

Exchange under the symbol “OR.DB”. The net proceeds from the Offering will be used to fund the acquisition of precious

metal royalties, streams, working capital, and general corporate purposes.

Record Gold Equivalent Ounces Earned

The Company ’s portfolio of producing royalty, stream and offtake interests delivered a record 20,990 GEOs in the fourth

quarter of 2017 for a total record of 58,933 GEOs for the f ull year 2017. The assets acquired from Orion were the major

contributors to the record quarterly GEOs earned by the Company, while Canadian Malartic continued to generate strong

results.

Overview of 2017 Financial Results

 Record revenues from royalties and streams of $93.8 million ($213.2 million i ncluding offtakes) compared to

$62.7 million in 2016;

 Gross profit of $59.5 million compared to $51.2 million in 2016;

 Impairment charge of $89.0 million on the Éléonore NSR royalty interest ($65.4 million, net of income taxes);

 Operating loss of $70.4 million compared to an operating income of $29.1 million in 2016;

 Net loss attributable to Osisko’s shareholders of $42.5 million or $0.33 per basic and diluted share, compared to net

earnings of $42.1 million or $0.40 per basic and diluted share in 2016;

 Adjusted earnings4 of $22.7 million or $0.18 per basic share4 compared to $34.2 million or $0.33 per basic share in

2016;

 Net cash flows provided by operating activities of $48.7 million compared to $53.4 million in 2016.

Revenues increased in 2017 mainly as a result of the acquisition of Orion’s Portfolio.

Gross profit reached $59.5 million in 2017 compared to $51.2 million in 2016 as a result of higher revenues. Cost of sales

increased from $0.1 million in 2016 to $125.6 million mainly as a result of the offtake agreements acquired through the

acquisition of Orion’s Portfolio. Under the offtake agreements, the metal is acquired from the producers at the lowest market

price over a certain period of time (quotational period), and is subsequently sold by Osis ko, resulting in a net profit that will

usually vary between 0% and 5% of the sales proceeds.

In 2017, the Company incurred an operating loss as a result of an impairment charge of $89.0 million on the Éléonore royalty

interest. Excluding the impairment c harge, operating income would have amounted to $18.6 million compared to $29.1

million in 2016. The decrease in operating income in 2017, in addition to the impairment charge, is mainly the result of the

transaction costs related to the acquisition of Orio n’s Portfolio, which amounted to $8.9 million and higher general and

administrative expenses (“G&A”), partially offset by higher gross profit. The increase in G&A expenses is mainly due to

higher salary expenses as a result of higher bonuses payable to man agement following the acquisition of Orion’s Portfolio,

higher share -based compensation expenses related to the deferred and restricted share units (higher number of units

outstanding and increase in the objectives achievements related to 2014 RSUs which v ested and were paid in September

2017) and higher general costs due to the increased activities of the Company in 2017. The year 2017 is the first year where

3 years of stock options, RSUs and DSUs are outstanding. Stock options and RSUs vest over a three -year period. Business

development expenses increased by $10.4 million mainly as a result of the transaction costs related to the acquisition of

Orion’s Portfolio, higher bonuses payable to management, higher share -based compensation expenses related to the

deferred and restricted share units and higher general costs due to increased activities in 2017.

The net loss attributable to Osisko’s shareholders in 2017 is mainly the result of the impairment charge of $89.0 million, a

lower operating income, a highe r foreign exchange loss, higher finance costs, the absence of dividend income following the

sale of the shares of Labrador Iron Ore Royalty Corporation in 2016 and early 2017, partially offset by higher interest income.

Adjusted earnings decreased to $22 .7 million compared to $34.2 million in 2016 as a result of higher G&A, lower dividend

income and higher finance costs, partially offset by higher gross profit.

Net cash flows provided by operating activities decreased in 2017 as a result of the fees rela ted to the acquisition of Orion’s

Portfolio and the settlement of restricted share units for $5.5 million, partially offset by higher gross profit.

Barkerville Gold Mines Ltd. (“Barkerville”) is currently carrying out a 160,000 meter exploration drilling program in the Cariboo

Mining District of central British Columbia and reported that it has received all permits t o initiate production from its Bonanza

Ledge underground project at an initial rate of 150,000 tonnes per year. In April 2017, Barkerville announced a new discovery

from its ongoing 160,000 metres Phase II Island Mountain and Valley Zone exploration drilli ng program at its Cariboo Gold

Project.

Osisko holds a 2.25% NSR royalty on the Cariboo gold project and has a right of first refusal relating to any gold stream offer

received by Barkerville with respect to the Cariboo gold project.

Falco Resources Ltd.

In October 2017, Falco Resources Ltd. (“Falco”) released6 a positive feasibility on the Horne 5 project. The feasibility study

indicated that, at a gold price of US$1,300/oz and using an exchange rate of C$1.00 = US$0.78, the Horne 5 Project would

generate an after -tax net present value, at a 5% discount rate, of US$602 million and an after -tax internal rate of return of

15.3%. As per Falco, in this scenario, the mine could become the next significant gold producer in Québec, with a production

profile averaging 219,000 payable ounces annually over the life of mine, with an all -in sustaining cash cost of US$399 per

ounce net of by -product credits and all -in cost, capital expenditures plus operating expenditures, estimated at US$643 per

ounce. The Environmental Impact Assessment study was filed with the authorities in December 2017.

On October 10, 2017, Osisko entered into a subscription agreement with Dalradian Resources Inc (“Dalradian”) pursuant to

which Osisko made an investme nt of $28. 3 million in Dalradian by way of a non -brokered private placement. The

subscription agreement entered into with Dalradian contains various covenants and rights, including among other things, a
