PRESS RELEASE

FOR IMMEDIATE RELEASE

YORBEAU APPROVES DRILLING PROGRAM TO TEST LEMOINE MINE EXTENSION AT

DEPTH IN CHIBOUGAMAU CAMP, QUEBEC.

Montreal, Quebec, September 17, 2020 – Yorbeau Resources Inc. (TSX: YRB) ("Yorbeau" or

the "Company") is pleased to report that a geological compilation and a borehole geophysics

modeling deliver high-priority targets along the highly prospective Lemoine horizon. These targets

are located approximately 400 metres down dip of the mined-out deposit and 800 metres from

the surface.

The Lemoine Mine is located 25 km south of Chibougamau and produced 0.76 Mt of high-grade

massive sulphide ore from 1975 to 1983 (Figure 1). With its 4.2% Cu, 9.6% Zn, 4.2 g/t Au and

83 g/t Ag, Lemoine is within the top 1% of all VMS worldwide (in term of grade). The deposit was

closed off by drilling below 400 metres vertical. However, the deepest hole drilled from

underground in this sector (hole 12L-27) returned a high-grade massive sulphide intersection of

43 cm grading 4.3% Cu, 6.3% Zn and 1.1 g/t Au (see Figure 2).

In 2013, hole LEM-63W was designed to make a follow-up on the 12L-27 intersection but did not

reach the target due to excessive deviation. Although, borehole geophysics in this hole detected

two off-hole conductors. Geophysical modeling made by INTER Géophysique shows a strongly

conductive plate of 250 Siemens (target #1) located 70 met res below 12L-27. In addition, a

second conductor of 70 Siemens (target #2) was detected along the Lemoine horizon, which has

been shifted by a mafic dyke (Figure 3). These conductors are open at depth.

Two holes for approximately 2500 metres are planned to test the se targets and borehole

geophysics will be completed. A drill permit has been received and Miikan Drilling Inc. will mobilize

to the property in the coming weeks as soon as a large drill rig is available.

G. Bodnar Jr., Company president commented: “The board of directors unanimously approved,

in accordance with Yorbeau’s strategic advisor, this exciting drilling program. A new high- grade

VMS discovery at Lemoine could be a game changer for Yorbeau’s Chibougamau projects

including Scott. We can’t wait to test these targets in the next few weeks.’’

Work is carried out by the Yorbeau personnel, under the supervision of Sylvain Lépine, M.Sc,

P.Geo. He is a qualified person (as defined by National Instrument 43-101) and has prepared and

approved the content of this release.

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 that feature infrastructure favourable for mining development. The newly acquired base

metal properties include the Scott Project in Chibougamau, which bears important mineral

resources (see the press release dated March 30, 2017) and on which a positive Preliminary

Economic Assessment was recently completed.
