PRESS RELEASE

FOR IMMEDIATE RELEASE

YORBEAU ANNONCES THE COMPLETION OF HOLE LEM-66W3 AND EXPLAINS TARGET

#1 AT THE LEMOINE PROJECT IN CHIBOUGAMAU, QUEBEC.

Montreal, Quebec, February 3, 2021 – Yorbeau Resources Inc. (TSX: YRB) ("Yorbeau" or the

"Company") announces completion of hole LEM -66W3 that was designed to test a strong

borehole geophysical anomaly (target #1) detected in hole LEM-66 at its Lemoine project in the

Chibougamau area of Quebec (see Yorbeau’s news releases dated January 20, 2021).

The Lemoine Mine is located 25 k ilometres south of Chibougamau (Figure. 1) and produced

758,000 tons of high-grade massive sulphide ore from 1975 to 1983. 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 s of grade).

This drilling program was a follow-up of the deepest hole drilled from underground in this sector,

hole 12L-27 (drilled in 1980) which returned a high-grade massive sulphide intersection of 43 cm

grading 4.3% Cu, 6.3% Zn and 1.1 g/t Au.

Hole LEM-66W3 intersected 0.6 metres of semi-massive pyrite and pyrrhotite with some traces

of sphalerite and chalcopyrite along the Lemoine horizon. This quantity and texture of sulfides,

especially pyrrhotite, explain the strong conductor previously modelled (target #1). The company

has decided to suspend drilling activities for now in order to evaluate other alternative options.

Other promising targets remain untested on the property especially target #2 area (Figure 2)

where the geophysical modelled plate is less conductive than target #1 (90 siemens Vs. 400

siemens). I n the light of current results , data suggest that target #2 could be explained by a

different type of mineralization. Moreover, hole L91-01 (drilled in 1991) located at the edge of this

modelled plate seems to support this hypothesis by returning 3.3 % Zn over 0.3 metres.

Another area with a strong discovery potential is located in the west part of the property at

relatively shallow depth. This area shows the largest hydrothermal alteration system observed at

Lemoine that covers 4 kilometres by 600 metres (Figure 3). This system that was delineated using

lithogeochimical data from outcrops and drilling , clearly cross -cut the Lemoine stratigraphy.

Further work s in this area should include borehole geophysical survey of historical holes,

especially in LEM-64 drilled by Cogitore Resources in 2008.

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 under way. 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 C ompany 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.
