Lundin Gold Reports 667.78 g/t over 7.50 Metres and 523.01 g/t Au over 8.25 Metres at FDNS

VANCOUVER, BC, May 5, 2026 /CNW/ - Lundin Gold Inc. (TSX: LUG) (Nasdaq Stockholm: LUG) (OTCQX: LUGDF) ("Lundin Gold" or the "Company") is pleased to report additional strong results from its ongoing conversion and near‑mine exploration drilling programs at the Fruta del Norte ("FDN") gold mine in southeast Ecuador. PDF Version 

The drilling programs delivered positive results across FDN, FDNS, and FDN East within the Company's mining property.  Notably, recent conversion drilling at FDNS delivered two of the highest grade‑thickness gold intercepts ever drilled at FDN, underscoring the growing importance of FDNS as a major source of high‑grade mineralization and supporting continued Mineral Resource and Mineral Reserve growth.

Highlights

Conversion Drilling

• FDNS: Recent drilling returned the highest‑grade intercepts ever recorded at FDNS, including two intervals that rank as the second and fourth highest grade-thickness gold intercepts drilled across the entire FDN mining property (Figure 1), reinforcing FDNS as a primary driver of recent and ongoing Mineral Resource and Mineral Reserve growth.

Exploration Drilling

• FDNS: Successfully confirmed mineralization continuity along the downdip extension of the deposit, outside the current Mineral Resource envelope, and highlighted areas with meaningful potential for further expansion.
• FDN East: Drilling confirmed northward continuity of the vein system beyond the inaugural Mineral Resource, returning the highest‑grade interval ever recorded at FDN East, and demonstrated continuity of newly discovered eastern veins, highlighting an expanding footprint and additional exploration upside.
• FDN: Drilling intercepted the upper continuity of the main FDN mineral envelope close to existing underground infrastructure, identifying additional near‑mine expansion opportunities.

Jamie Beck, President and CEO, commented, "Conversion drilling at FDNS has consistently delivered some of the best results at FDN since its discovery, and these results are no exception, including two of the highest grade-thickness gold intercepts ever drilled at Fruta del Norte.   Exceptional systems tend to surprise to the upside, and it is clear there remains significant potential for additional expansion.

At FDN East, the highest‑grade interval ever reported along the extension of the mineral envelope confirms meaningful exploration upside, while at FDN, positive results close to existing underground development highlight opportunities for further growth.  With 17 rigs currently operating at site between the epithermal gold deposits and copper gold porphyry targets, we remain confident in our ability to continue creating value through disciplined exploration across this remarkable mining district."

DRILLING PROGRAMS

Lundin Gold's near‑mine exploration strategy is focused on extending mine life through the discovery and delineation of new mineralized zones near existing infrastructure.  Since the start of commercial production, these efforts have contributed to significant Mineral Reserve growth.

2026 is set to be a landmark year for the Company, with the largest exploration program in its history, totaling approximately 133,000 metres of planned drilling.  Conversion and near‑mine exploration activities will account for approximately 125,000 metres, combining surface and underground drilling aimed at Mineral Resource conversion, the discovery and delineation of new mineralized zones, and the potential identification of new gold and copper‑gold resources across the Fruta del Norte mining property.

FDNS

The 2026 underground conversion drilling program continues to advance across several sectors of FDNS, where the Company declared an inaugural Mineral Reserve of 0.54 Moz (2.50 Mt at 6.66 g/t Au) approximately two years after the deposit's discovery.  This reserve declaration followed a succession of consistently strong conversion drilling results that have exceeded expectations.

Recent drilling has focused on the central and northern sectors of the deposit and continues to intercept mineralization consistently, further validating the geological model (Figures 2 and 3).  The program returned the highest‑grade intercepts ever recorded at FDNS, including FDN‑C25‑374 (667.78 g/t Au over 7.50 m; 60.19 g/t Au over 13.95 m) and FDN‑C26‑380 (523.01 g/t Au over 8.25 m; 32.94 g/t Au over 4.55 m) and highlighted additional high‑grade zones within the established mineral envelope.

Underground exploration drilling continues to extend the FDNS mineral envelope beyond the current Mineral Resource.  Hole UGE‑S‑26‑472 (22.97 g/t Au over 5.00 m) intercepted multiple mineralized veins at depth, indicating further expansion potential in the northern sector of the deposit (Figures 2 and 3).  Results received to date are summarized in Tables 1 and 4.

FDN EAST

FDN East is a buried epithermal system composed of multiple subparallel north‑south‑trending veins located approximately 100 metres east of FDN's existing underground infrastructure.  Drilling in 2025 defined a deposit footprint of 500‑metre strike length and supported an inaugural Inferred Mineral Resource of 0.42 Moz Au (2.17 Mt at 6.01 g/t Au).

The mineral envelope remains open, and underground exploration drilling is ongoing.  Along the northern extension, drilling returned the highest‑grade intercept ever recorded at FDN East, confirming mineral continuity and highlighting strong exploration potential along strike (Figure 4). In addition, drilling confirmed the continuity of newly identified veins beyond the initial Mineral Resource and the deposit footprint strike length is now 500 metres West to East and 800 metres North to South and open for further discovery to the North, East, and South.  Results received to date are presented in Tables 2 and 4.

FDN

At FDN, underground exploration drilling intercepted the upper extension of the deposit along the contact with the Suarez conglomerate sequence, close to existing underground infrastructure.  Highlights include UGE‑26‑479 (10.55 g/t Au over 23.55 m) and UGE‑26‑461 (8.32 g/t Au over 7.85 m), underscoring significant exploration potential in areas readily accessible from current mine development (Figure 5).  Results received to date are summarized in Tables 3 and 4.
