Yorbeau Announces Receipt of Scheduled Cash Payment From IAMGOLD in Order to Maintain its Option on the Rouyn Property

MONTREAL, June 11, 2020 - 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 a cash payment to Yorbeau in the amount of $500,000 corresponding to the second 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 year, IAMGOLD has met its expenditure obligation to incur a minimum of C$2 million exploration expenditures on the property. Moreover, IAMGOLD has already exceeded their minimum drilling commitment (completion of a minimum of 20,000 metres of diamond drilling within the first two-years) by drilling to date more than 30,000 metres on the Rouyn property.

G. Bodnar Jr., Company president commented: "We continue to be extremely pleased by our business relationship with IAMGOLD. This payment reflects the satisfaction of our partner in the results obtained to date from infill and evaluation drilling programs. We are looking forward to resuming drilling activities on Astoria in the coming weeks."

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 accordance with Regulation NI 43-101.

The Lac Gamble zone is located between the Augmitto 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 totaling C$4 million and completing exploration expenditures totaling 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 return production royalty, by paying Yorbeau the lesser of C$15 per resource ounce or C$30 million. IAMGOLD is in the second year of the option agreement.
