Osisko Acquires Gold Stream on Aquila's Back Forty Project in Michigan, USA

MONTREAL, QUEBEC--(Marketwired - Nov. 9, 2017) - Osisko Gold Royalties Ltd (the "Company" or "Osisko") (TSX:OR)(NYSE:OR) is pleased to announce that its wholly-owned subsidiary, Osisko Bermuda Limited ("OBL") has agreed to acquire a gold stream ("Gold Stream") with reference to the future gold produced from the Back Forty property ("Back Forty" or the "Project") located in Michigan, USA from Aquila Resources Inc. ("Aquila") (AQA: TSX). OBL will make a staged upfront cash deposit 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.

Back Forty is a development-stage project located in Michigan's Upper Peninsula. The deposit is a zinc and gold-rich volcanogenic massive sulfide (VMS) deposit located along the mineral-rich Penokean Volcanic Belt. Over the past 10 years, Aquila and various joint venture partners have invested more than $75 million exploring and advancing Back Forty. Aquila completed a preliminary economic assessment for the Project in 2014 that demonstrated positive economics, and estimated total payable gold production of 532,000 ounces, including 145,000 ounces in the first year. Aquila is currently completing a feasibility study for the Project, which is expected to be released in early 2018.

In addition to the Gold Stream, OBL has agreed to purchase units in the amount of US$10 million as part of a concurrent private placement with Aquila.

OBL currently owns a 75% stream on all silver produced on the Project (the "Silver Stream"). The Silver Stream was acquired in July 2017 through the acquisition of the Orion Mine Finance portfolio.

The Gold and Silver Streams on Back Forty provide Osisko with exposure to:

• a significant precious metals streaming interest on an advanced North American project;
• mid-term cash flow from a premier jurisdiction;
• upside potential through further exploration of the Project; and
• maintains the Company's focus on low-risk jurisdictions.

The Gold Stream Purchase

Pursuant to a gold purchase agreement to be entered into by OBL and Aquila, OBL will purchase a gold stream equivalent to 18.5% of the refined gold from the Project until 105,000 ounces of gold have been delivered (the "Threshold Stream"), and 9.25% of the refined gold for the remaining life-of-mine (the "Tail Stream"). Payable gold under the Stream will be subject to minimum payability rates based on the product produced. As consideration for the Gold Stream, OBL will pay to Aquila a staged upfront cash deposit of up to US$55 million (the "Deposit") plus ongoing payments equal to 30% of the spot price of gold on the day of delivery, to a maximum of US$600 per ounce.

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

1. US$7.5 million payable on closing of the Gold Stream;
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 (the "Fourth Deposit"), subject to the CoC Provision (as defined herein).

In the event of a change of control of Aquila prior to the advancement of the Fourth Deposit, the person or entity acquiring control over the Project may elect to forego the Fourth Deposit, in which case the Threshold Stream and Tail Stream will reduce to 9.5% and 4.75%, respectively (the "CoC Provision"). All other terms and conditions of the Gold Stream will remain unchanged.

The Gold Stream will be secured by a first priority lien on the Project and all assets of Aquila. The security for the Gold Stream will rank pari passu with the security for the Silver Stream.

The Private Placement

As part of the transaction, OBL has agreed to purchase US$10 million of units in Aquila at a price of C$0.26 per unit (the "Equity Subscription"). Each unit will be comprised of one common share and one quarter of one common share purchase warrant, with each full warrant entitling OBL to purchase one common share of Aquila for C$0.34 for a period of 42 months following closing of the Equity Subscription. On closing of the Equity Subscription, OBL is expected to own approximately 14.5% of Aquila's issued and outstanding common shares ("Aquila Common Shares"). So long as OBL continues to hold more than 10% of the Aquila Common Shares, OBL will have the right to nominate one representative to Aquila's board of directors and the right to participate in any future equity or equity-linked offerings to maintain its pro rata ownership interest. Joseph de la Plante, current Vice President, Corporate Development of Osisko, will be appointed to the board of Aquila immediately upon close.

All securities issued to OBL under the private placement will be subject to a four-month hold period from the date of issuance of the securities, pursuant to applicable securities legislation.

Closing of the Gold Stream and Equity Subscription is expected to be on or around November 10, 2017 and is subject to regulatory approvals.
