Osisko provides senior secured loan to Highland Copper

(Montreal, December 16, 2014) Osisko Gold Royalties Ltd (OR:TSX) (“Osisko” or the “Company”) is pleased to announce the closing of a transaction (the “Transaction”) with Highland Copper Company Inc. (“Highland”) whereby Osisko has provided Highland with a C$10 million secured loan in exchange for, among other things, a 3% sliding-scale NSR royalty on all metals produced from the White Pine North project to be acquired by Highland. Under the Transaction, Highland also granted Osisko an exclusive option to purchase a 100% silver NSR royalty on all future silver production from Highland’s White Pine North and Copperwood Projects (collectively, the “Michigan Projects”).

Secured Note and White Pine North Royalty

Under the terms of the Transaction, Osisko has provided Highland with a C$10 million loan, secured against all of Highland’s assets (the “Secured Loan”), until the earlier of such time that Highland completes its acquisition of the White Pine North project, or December 31st 2015. Upon Highland completing its acquisition of the White Pine North project, the Secured Loan will be assigned to Highland in exchange for a 3% sliding-scale NSR royalty on all metals from the White Pine North project (the “White Pine North Royalty”). The White Pine North Royalty has a base rate 3% NSR and increases by 0.01% NSR for every $0.01 increase in the copper price above $3.00 per pound.

Silver Royalty Option

Additionally, Osisko has been granted an option to purchase a 100% silver NSR royalty on the Michigan Projects (the “Silver Royalty”) for future cash consideration of US$26 million should Osisko exercise its exclusive option to acquire the Silver Royalty. At its sole discretion the Company may elect to purchase the Silver Royalty within 60 days following the delivery by Highland of a feasibility study on the Michigan Projects.

Board Representation

Osisko will have the right to nominate one director to the Highland board following the completion of the Secured Loan. Osisko has the right to nominate one additional director to the Highland board upon exercise of the Silver Royalty option.

About the Michigan Projects

Highland Copper Company Inc. is a Canadian mining company focused on exploring and developing copper projects within the Upper Peninsula of Michigan, United States of America (“USA”). Highland’s portfolio of projects includes the recently acquired Copperwood project, the White Pine North project and the Keweenaw project. The Upper Peninsula of Michigan is well known for hosting significant economic concentrations of copper in stratabound deposits. These deposits are unique for their uniform copper grade distribution over several tens of km2 in sub horizontal ore bodies suitable for high tonnage underground mining with minimum environmental impact. During its historical productive period from 1845 to 1977, the area produced in excess of 11 billion pounds of copper. It is one of the major copper mining districts in the USA. Highland has put in place an experienced technical team with the objectives of confirming the historical resources on the White Pine North and Copperwood projects

White Pine North

The White Pine North copper deposit is located in the western Upper Peninsula of Michigan on the south side of Lake Superior. The White Pine mine produced 4.5 billion pounds of copper between 1952 and 1995. In 1995, Upper Copper Range Company (“CRC”), a subsidiary of First Quantum Minerals, estimated a historical resource of 118.7 million short tons averaging 1.04% Cu, for a total contained 2.52 billion pounds of copper.

This historical estimate was made prior to the existence of National Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI 43-101”) and does not use the categories set out in the CIM Definition Standards on Mineral Resources and Mineral Reserves and mandated by NI 43-101. The terms “proven and probable reserves” are historical terms used by CRC, not comparable to the CIM defined Probable Mineral Reserve and Proven Mineral Reserve, and should be compared to a potential mineral deposit requiring further exploration drilling to define an initial resource. A qualified person (QP) has not done sufficient work to classify the historical estimate as a current mineral resource and the historical estimate is not being treated as current mineral resources and should not be relied upon.

Copperwood Project

The Copperwood deposit is located in Gogebic County in the Upper Peninsula of Michigan, USA, about 35 kilometers west of the White Pine mine. Copperwood is a feasibility stage project. Highland acquired the Copperwood Project from Orvana Minerals Corp. (“Orvana”) on June 17, 2014. In 2008 Orvana began delineation drilling and environmental baseline studies that led to engineering studies and a proposed mine plan. In early 2013, the permits that would allow the development and mining of the deposit were granted.

Copperwood was discovered in 1956 and boasts the highest-grade of all known sediment-hosted copper deposits in the Upper Peninsula. It is geologically very similar to the White Pine deposit. Golder Associates Ltd. prepared a NI 43-101 technical report on the Copperwood Project effective as of March 17, 2014. Highland is reporting the Orvana Minerals mineral reserve and resource estimates as historical data. At a 0.8% copper cut-off grade, the historical estimate totals 30.1 million tonnes at 1.65% copper and 4.34 g/t silver in the measured and indicated resource category. At a 0.8 wt. % copper cut-off grade, the historical estimate totals 2.9 Mt at 1.07 wt.% copper and 2.01 g/t silver in the inferred resource category. A qualified person (QP) has not done sufficient work to classify the historical estimate as a current mineral resource and the historical estimate is not being treated as current mineral resources and should not be relied upon.
