PRESS RELEASE

FOR IMMEDIATE RELEASE

Yorbeau Resources Begins Exploration Program on its Beschefer, Selbaie West and

Allard Properties in Northwestern Québec

Montreal, Québec, February 19, 202 6 – Yorbeau Resources Inc. (TSX: YRB) ( “Yorbeau” or the

“Company”) commenced an exploration drilling program in January on its Beschefer and Selbaie West

properties near the former Selbaie mine, as well as on the Allard property located southwest of the town

of Matagami. The programs consist of approximately 2,545 meters of drilling on the Beschefer property,

2,100 metres on the Selbaie West property and 1,000 meters on the Allard property.

Beschefer Property

The Beschefer property is located 9 km southeast of the former Selbaie producer (historical production of

56.9 Mt @ 0.87% Cu, 1.85% Zn, 39 g/t Ag) 1 and immediately east of the B -26 Zone currently being

developed by Abitibi Metals Corp. and SOQUEM (13.0 Mt Indicated at 2.1% Cu Eq and 12.3 Mt Inferred

at 2.2% Cu Eq)2,3 (Figure 1). The 2026 program aims to trace the B -26 Zone near surface and to test a

series of induced polarization anomalies along the extension of the B -14 gold zone located approximately

2 km to the east. Drilling is currently underway, and results will be released as soon as they become

available.

Selbaie West Property

Drilling on this property will begin once all required permits have been obtained. The objective of this

campaign is to test the continuity of newly identified copper, zinc, gold and silver zones discovered over

the past two years by SOQUEM (Figure 1) on the adjacent Wagosic property. The Selbaie West property

is located less than 3 km west of Soquem’s recent discoveries on the Wagosic property (Hole 1338-25-

087 cut a mineralized zone of 296.9 meters at 1.47% Zn, 0.20% Cu, 0.06 g/t Au and 18.3 g/t Ag) 3,4 within

the Selbaie horizon.

This horizon extends onto Yorbeau’s property for more than 9 km (see Figure 1). In 2008, Yorbeau

completed a series of drill holes near the eastern boundary of the Yorbeau- SOQUEM properties and

identified the Selbaie horizon, which returned several copper and zinc values. Additional results were

obtained in the southwest portion of the property, possibly within the B -26 horizon. Furthermore, a 2012

drill hole (SW-12A) intersected a zone of more than 20 meters of disseminated mineralization containing

copper and nickel values within a gabbro. The 2026 program includes drilling in this sector to assess the

significance of this copper and nickel intersection.

Over the past 24 months, the area surrounding the former Selbaie Mine north of La Sarre has seen

significant developments including the advancement of the B -26 Zone and the discovery of significant

copper and zinc mineralization northwest of the Selbaie Mine by SOQUEM . Major exploration work ,

including more than 56,000 meters of drilling, is ongoing in the area.

Yorbeau holds a strategic land position neighboring these two projects. Based on Yorbeau’s geological

interpretation, the host rocks of these deposits could logically extend for several kilometers within the

boundaries of the Beschefer and Selbaie West properties (Figure 1). The Company plans to conduct

additional work over the next 12 months on both properties.

Allard Property

The Allard property is located 30 km southwest of the town of Matagami within the western extension of

the Casa Berardi corridor. Three drill holes were completed in January 2026 to test an induced

polarization anomaly in the eastern sector and to follow up on drilling completed by Canamax in 1988 in

the central sector.

The drill holes intersected multiple multi-meter sections of quartz veins containing pyrite and traces of

arsenopyrite. Approximately one hundred gold assays are currently pending, and results will be released

as soon as they become available.

The scientific and technical content of this press release has been reviewed, prepared and approved by

About Yorbeau Resources Inc.

Yorbeau Resources is a Canadian public company (TSX: YRB) active in gold and base metal exploration

in Quebec, Canada. The Company is focused on securing a partner to further explore and advance its

zinc and copper deposit at Scott Lake, near Chibougamau, Quebec (see Yorbeau’s National Instrument

43-101 compliant technical report dated December 6, 2017, titled “ Technical Report on the Preliminary

Economic Assessment for the Scott Lake Project, Northwestern Québec, Canada ,” available on the

Company’s SEDAR+ profile at www.sedarplus.ca). Yorbeau also has the necessary funds to explore its

properties located in the Détour, Joutel and Selbaie areas of northwestern Quebec. These properties

include the Beschefer property, which is adjacent to the B-26 base metal deposit currently being explored

by Abitibi Metals Corp. and the Selbaie West property adjacent to SOQUEM’s Wagosic property, where

base metal values are currently being intersected along the Selbaie mine horizon.
