PRESS RELEASE

FOR IMMEDIATE RELEASE

Yorbeau Resources Inc. Files Technica l Report on Preliminary Economic

Assessment of Scott Lake Deposit.

 Project indicates pre-tax IRR of 16.6% with an NPV8% of $146 million.

Montréal, December 19, 2017 - Yorbeau Resources Inc. (TSX: YRB) (the “Company” or

“Yorbeau”) is pleased to announce that it has filed on SEDAR a Technical Report in compliance

with National Instrument 43-101 (NI 43-101) on a Preliminary Economic Assessment (“PEA”)

of the Company’s 100% owned Scott Lake Proj ect near Chibougamau, Quebec. The Technical

Report was prepared by Roscoe Postle Associates Inc. (“RPA”).

Under the base case PEA, the Scott Lake minera lized material is fed to a new 2,500 tonne-per-

day concentrator plant located at the mine s ite. Results indicate positive economics with a pre-

production capital expenditure of $215 million, a net pre-tax cash flow of $519 million, an

Internal Rate of Return (“IRR”) of 16.6%, a pre-tax Net Present Value (“NPV”) of $146 million

at an 8% discount rate, and a mine life of 15 years.

The PEA economic analysis is based in part on Inferred Mineral Resources, and is preliminary in

nature. Inferred Mineral Resources are considered too geologically speculative to have mining

and economic considerations applied to them and to be categorized as Mineral Reserves. There is

no certainty the economic forecasts based on this PEA will be realized.

Yorbeau's news release dated November 20, 2017 summarizes the assumptions and key results

contained in the Technical Report. There are no material differences between the key results

contained in Yorbeau's news release dated N ovember 20, 2017 pertaining to the Scott Lake

deposit, from those contained in the Technical Report filed today. Economic analysis in the

Technical Report includes both pre-tax and after-tax results.
