MANDALAY RESOURCES CORPORATION RECEIVES MINING PERMIT ON EASTERN EXTENSION ZONE, BJÖRKDAL MINE, SWEDEN

TORONTO, July 20, 2023 /PRNewswire/ -- Mandalay Resources Corporation ("Mandalay" or the "Company") (TSX: MND) (OTCQB: MNDJF) is pleased to receive the mining concession permit to produce in the Eastern Extension Zone at its Björkdal operation from Bergsstaten (Mining Inspectorate of Sweden).

Frazer Bourchier, President and CEO of Mandalay commented:

"I am very pleased to announce that we have successfully obtained the mining concession for the newly designed Eastern Extension of our Björkdal mine. This significant development grants us the extension of the mining envelope by an additional 350 metres, effectively encompassing the entire resource base that has been drilled and defined over the past two years.

"The inclusion of the Eastern Extension area aligns with our strategic objective of incorporating higher gold grade and margin ounces into our near-term production profile at Björkdal. By integrating this addition into our mine schedule, we believe that it will further contribute to our intended growth and success at Björkdal."

Exploration to Date

In 2021, the Company discovered the Eastern Extension of the Main Zone and Central Zone. Following the recognition of the mineralized potential, a series of drilling programs were dedicated to defining this enriched veining, with each program yielding exceptional grades and furthering our understanding of this domain. For further details, please refer to the news releases dated: July 18, 2023; February 22, 2023; June 21, 2022; and January 24, 2022.
