Yorbeau Resources Inc. Files Technical Report on Preliminary Economic Assessment of Scott Lake Deposit

MONTRÉAL, QUÉBEC--(Marketwired - Dec. 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 Project near Chibougamau, Quebec. The Technical Report was prepared by Roscoe Postle Associates Inc. ("RPA").

Under the base case PEA, the Scott Lake mineralized material is fed to a new 2,500 tonne-per-day concentrator plant located at the mine site. 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 November 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.
