Ron Hochstein, President and CEO, commented, "I am pleased to announce additional results from Lundin Gold's 2023 exploration programs. The conversion program has successfully defined zones of high-grade mineralization within the FDN deposit that we expect will continue converting resources to reserves. Results from the near-mine program confirm the continuity and expansion potential of recent discoveries, Bonza Sur and FDNS, and improve our understanding of their mineralization geometry. Nine rigs are currently turning on our conversion and exploration programs and a minimum of 43,000 metres of drilling are planned in 2023. This represents the largest drill program in the district since 2007."

CONVERSION PROGRAM

Lundin Gold has been advancing its conversion program at FDN, with the objective of converting Mineral Resources to Mineral Reserves. In the past months, conversion drilling has focused on the southern extension of FDN, where high-grade intercepts are associated mainly to vein and/or veinlet zones hosted in volcanic or porphyritic intrusive rocks. Drilling results from the program have significantly increased confidence in the geologic model of the southern extension of the deposit and have revealed a vein type higher grade mineralization within the mineral inferred envelope (Figure 1). The 2023 program is planned to comprise of approximately 7,600 metres of drilling and since January, a total of 4,612 metres across 30 drill holes have been completed. Assay results received to date are presented in Tables 1 and 3 at the end of this release.

NEAR-MINE EXPLORATION PROGRAM

The near-mine program focuses on exploring sectors located along trend of the FDN deposit and within extensions of its major controlling structures. Initial drill results published in January and May (see news releases published on January 26[th] and May 4[th], 2023) discovered two new mineralized zones to the south of the FDN deposit, FDNS and Bonza Sur. In recent months, results from the near-mine program have confirmed continuity of mineralization at both targets, and have improved our understanding of the geometry of these vein systems (see Figures 1 and 3). In 2023, a total of 12,363 metres across twenty-four holes, from surface and underground, have been completed. The most recent assay results are presented in Tables 1 and 3 at the end of this release. Results are still pending for some of the reported drill holes.

FDN South (FDNS)

At FDNS, progress was made in delineating this buried epithermal mineralization located immediately south of the current resource envelope of FDN and to the west of the East Fault. Six new drill holes were completed during the quarter and reveal the occurrence of a series of subparallel mineralized veins disposed in the northeastern to southwestern direction, showing similar hydrothermal alteration to that found at FDN. This vein system remains open along strike to the southwest, as well as along the downdip continuity, below the Suarez Basin cover. Importantly, improvements in understanding the veins' geometry has allowed for a redefinition of the drilling program. Drilling at FDNS is ongoing with one rig turning.

Bonza Sur

At Bonza Sur, drilling is enabling expansion of this target located one kilometre south of FDN. Five new drill holes have been completed and results included multiple exciting intersections associated with veins/veinlets of quartz and sulfides (mainly sphalerite and galena), minor chalcedony and manganoan-carbonate. Mineralization has been intercepted for 500 metres along strike from north to south and 300 metres along the downdip and remains open in all directions. Drilling at Bonza Sur is planned to continue to focus on the 1.2 kilometre long soil geochemical anomaly to the south and a systematic follow up will be initiated focused on the higher-grade intercepts returned from this target. Two rigs are currently turning at Bonza Sur (see Figures 2 and 3).

Exploring for new targets

The near-mine exploration program has also discovered new targets of interest through a detailed geological interpretation of exploration data and additional surface work. A drill program was initiated in the second quarter and aims to test the high potential targets near the FDN deposit. Five drill holes, four from underground and one from surface, were completed in the second quarter and intercepted zones of hydrothermal alteration hosted along the downdip extension and to the east of FDN. The program is ongoing with two rigs turning and is currently testing the FDN North and FDN East targets.

REGIONAL EXPLORATION PROGRAM

The 2023 regional exploration program continues to advance in the southern region of the Suarez Basin with a total of 2,796 metres completed to date. Targets of interest, such as Quebrada La Negra and Crisbel, located along the Basin's western border have been the primary focus. The 2023 regional drilling program comprises 12,500 metres of drilling and a second rig was recently added to the program to advance exploration at additional targets.
