FOR IMMEDIATE RELEASE

YORBEAU ANNOUNCES RECEIPT OF SCHEDULED OPTION PAYMENT OF $750,000 FROM

IAMGOLD IN ORDER TO MAINTAIN ITS OPTION ON THE ROUYN PROPERTY

Montreal, December 15, 2021 – Yorbeau Resources Inc. (TSX: YRB) ( “Yorbeau” or the “Company”) is

pleased to announce that in order to maintain its option to purchase a 100% interest in the Rouyn property,

IAMGOLD Corporation (“IAMGOLD”) has made the next option cash payment to Yorbeau in the amount of

$750,000 corresponding to the fourth in a series of scheduled cash payments to be made to Yorbeau during

an Expenditure Period of 48 months.

The terms of the definitive option agreement were announced in the Company ’s press release dated

December 17, 2018 . Among other commitments, IAMGOLD must make scheduled cash payments in an

aggregate amount of C$4 million during the Expenditure Period. In the first three years, IAMGOLD has met

and exceeded its expenditure obligation of C$6.5 million in exploration on the property. In 2022, IAMGOLD

plans to continue the evaluation of the resource potential on the project and will complete an additional

6,000 metres of diamond drilling on selected zones of mineralization to support a future Mineral Resource

Estimate. In 2022, IAMGOLD plans to continue the evaluation of the resource potential on the project and

will complete an additional 6,000 metres of diamond drilling on selected zones of mineralization to support

a future Mineral Resource Estimate.

G. Bodnar Jr., President of the Company, commented: “We are very pleased to continue to work with our

exceptional partner IAMGOLD. This fourth payment reflects the satisfaction of our partner in the results

obtained to date from infill and evaluation drilling programs. We are looking forward to resum ing drilling

activities in the coming year.”

About the Rouyn Gold Project

The Rouyn Gold Property is located about 4 km south of Rouyn- Noranda, Quebec. With a long history of

mining, the city of Rouyn- Noranda offers many advantages for mining and exploration, including political

and social stability, good access and infrastructure, skilled mining personnel, and one of the most mining-

friendly jurisdictions in the world.

The property covers a 12-kilometre stretch of the Cadillac-Larder Lake Break and contains four known gold

deposits along the 6- km Augmitto-Astoria corridor situated on the western portion of the property. Two of

the four deposits, Astoria and Augmitto, benefit from established underground infrastructure and have been

the subject of technical reports that include resource estimates that were previously filed in acc ordance

with Regulation 43-101.

The Lac Gamble zone is located between the Augmit to and the Astoria deposits. The exploration target

potential at Lac Gamble is interpreted to be between 400,000 and 600,000 ounces of gold at a grade

between 7.0 and 8.5 g/t Au. The potential quantity and grade of the exploration targets referred to are

conceptual in nature and insufficient exploration work has been completed to define a mineral resource.

The property may require significant future exploration to advance to a resource stage and there can be no

certainty that the exploration target will result in a mineral resource being delineated. The exploration targets

are consistent with similar deposits in the area, deposit models or derived from initial drilling results.

IAMGOLD signed a definitive option agreement in December 2018, whereby IAMGOLD has the option to

acquire a 100% interest in the Project by making scheduled cash payments total ling C$4 million and

completing exploration expenditures total ling C$9 million over a four -year period. Exploration programs

must include the completion of a minimum of 20,000 metres of diamond drilling within the first two years of

the option. By the end of the expenditure period, IAMGOLD must complete a NI 43-101 compliant resource

estimate, after which IAMGOLD, at its election, can purchase a 100% interest in the Project, subject to a

2% net smelter returns production royalty, by paying Yorbeau the lesser of C$15 per resource ounce or

C$30 million. IAMGOLD is in the third year of the option agreement.
