LUNDIN GOLD EXPANDS ITS 2023 NEAR-MINE EXPLORATION PROGRAM

Lundin Gold Inc. (TSX: LUG ) (Nasdaq Stockholm: LUG ) (OTCQX: LUGDF) ("Lundin Gold" or the

"Company") is pleased to announce that for the second time this year the Company is expanding its 2023

near-mine exploration progr am at its Fruta del Norte (“FDN”) operation in southeast Ecuador . The

Company plans to increase the 2023 near-mine drilling program by 7,500 metres to a minimum of 30,000

metres to accelerate delineation of new targets and continue to explore other sectors along FDN’s major

structures. The 2023 near-mine program was originally planned for 15,500 metres and increased to 23,000

meters in May. The regional exploration program continues unchanged.

As a result of improved productivities in the field, t he expanded program is expected to be completed

within the revised near-mine exploration budget of $12.9 million announced earlier this year. Six rigs (one

underground and five on surface) are currently operating on the near-mine program. Three additional rigs

are also turning on the Company’s other programs, including one underground on the conversion program

and two surface rigs on the regional program.

Ron Hochstein, President and CEO, commented, “I am pleased to announce further expansion of our near-

mine exploration program. Results from the near -mine program have improved our understanding of

many targets within this highly prospective district, leading to the current program now being almost

double what was originally planned for 2023. A minimum of 50,000 metres of drilling is planned across the

conversion, near-mine and regional programs in 2023. This represents the largest drill program in the

district since 2007.”
