MONTREALJan. 29, 2019 - Yorbeau Resources Inc. (TSX: YRB) ("Yorbeau" or the "Company") is pleased to announce that diamond drilling has commenced at its Scott project in the Chibougamau area of Quebec.

The Scott project contains a number of zinc-copper-gold-silver massive sulphide and stringer sulphide zones located in northwestern Scott Township.  Based on a Preliminary Economic Assessment (PEA) completed in late 2017 by Roscoe Postle Associates (RPA), the project represents an opportunity to develop an operating mine located within close proximity to the towns of Chibougamau and Chapais, a typical northern mining environment, offering the advantages of living facilities and availability of manpower, equipment and materials required to develop and operate the project. The project site has existing access and can be serviced with available hydroelectric power from the provincial grid located nearby. Results of the PEA 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 millionat an 8% discount rate, and a mine life of 15 years.

While the PEA contemplates extraction of 12 million tonnes (Mt) at grades of 4.14% Zn, 0.81% Cu, 27 g/t Ag, and 0.24 g/t Au over 15 years of mine life, the RPA report also highlights that exploration potential exist to increase Mineral Resources and, based on the significant amount of drilling already done on the Scott deposit, one of the main areas of potential for increasing resources is west of the regional Gwillim Lake fault, at depth. Recent structural interpretation suggests that the CFO Lens and smaller high grade massive sulphide zones may in fact represent structural "rafts" caught within the fault corridor, and which may have been dragged into the northeast trending fault corridor from an unknown source. If this is the case, interpretation work suggests that the primary source of those rafts may be located at depth, west of the fault, and south of the known Scott mineralized corridor. Company management considers that this target represents tremendous potential upside for the project, and the on-going surface drilling program is designed to test this.

The program is planned in two phases totalling about 5,000 metres of drilling consisting of shallow holes to investigate actual displacement of the Gwillim fault, followed by deep holes and wedge-cuts to explore the Scott horizon down-plunge from the known resources (Figure 1).

Gérald Riverin, Company president commented: "We are excited to be drilling again at the Scott project. While the initial Preliminary Economic Evaluation was positive, success in the on-going program could be a real game changer for the project, not only because of the potential added tonnage or grade of the resources, but most importantly because the added tonnage could perhaps justify sinking a production shaft which could help increasing production rate while reducing unit costs. In the meantime, discussions are on-going with potential partners to advance the project."

About Yorbeau Resources Inc.

The Rouyn Property, wholly-owned by the Company, contains four known gold deposits in the 6‑km‑long Augmitto-Astoria corridor situated on the western portion of the property. The Company signed a definitive agreement in December 2018, whereby IAMGOLD has the option to acquire a 100% interest in the Rouyn property, and a major drilling program is underway. Two of the four deposits, Astoria and Augmitto, benefit from substantial underground infrastructure and have been the subject of technical reports that include resource estimates and that were filed in accordance with Regulation 43-101. In 2015, the Company expanded its exploration property portfolio by acquiring strategic base metal properties in prospective areas of the Abitibi Belt of Quebec and Ontario that feature an infrastructure favourable for mining development. The newly acquired base metal properties include the Scott Project, which bears important mineral resources (see the press release dated March 30, 2017) and on which a positive Preliminary Economic Assessment was recently completed.
