Updated Mineral Reserves at Fruta del Norte of 5.02 million ounces
VANCOUVER, BC, Feb. 27, 2023 /CNW/ - Lundin Gold Inc. (TSX: LUG) (Nasdaq Stockholm: LUG) (OTCQX: LUGDF) ("Lundin Gold" or the "Company") is pleased to announce its updated estimates of Mineral Resources ("Resources") and Mineral Reserves ("Reserves") as at December 31, 2022 for its Fruta del Norte gold mine ("FDN") in Ecuador. The updated estimate builds from the Company's previously reported estimates of Resources and Reserves as at April 30, 2016 ("2016 estimate")1. The tables of the updated Resources and Reserves can be found at the end of this release. All amounts are in U.S. dollars unless otherwise indicated. View PDF version.
Highlights
- Measured and Indicated ("M&I") Resources are reported at 23.0 million tonnes ("Mt") with an average grade of 9.20 grams per tonne ("g/t") containing 6.8 million ounces ("Moz") of gold.
- A total of 9.3 Mt with an average grade of 12.09 g/t containing 3.6 Moz of gold are now categorized as Measured Resources as a result of an improved understanding of the deposit geology. The Company reported no estimates of Measured Resources in the 2016 estimate.
- Proven and Probable Reserves for FDN are reported at 18.0 Mt with an average grade of 8.68 g/t containing 5.0 Moz of gold.
- With this update, Lundin Gold has replaced all Reserves mined from the beginning of operations in late 2019 and added additional Reserves.

1 For details of the 2016 estimate, please refer to the technical report entitled "Fruta del Norte Project Ecuador NI 43-101 Technical Report on Feasibility Study", dated June 2016 with an effective date of April 30, 2016, filed on SEDAR under the Company's profile at www.sedar.com. |
- In addition, the new estimate includes Reserves in the Proven category which demonstrates greater confidence in the updated Reserves.
- Expansion of Proven and Probable Reserves into the southern portion of the deposit underlines the significant potential for further Reserve replacement from additional drilling in this sector.
Ron Hochstein, President and CEO, commented, "I am pleased to announce that the Company has successfully replaced all mined Reserves since the beginning of operations and added additional Reserves, a significant achievement for a large scale producing asset like FDN. These results demonstrate the exceptional value we have added through our conversion drilling program. Importantly, there are still 1.7 Moz of Inferred Resources at FDN, which we believe will play a significant role in continuing to replace production in the future. We expect that this updated Resource and Reserve estimate is only the first step in continuing to expand the total minable ounces of gold, allowing Fruta del Norte to continue production for many years to come."
A technical report for FDN, prepared in accordance with NI 43-101, will be filed under the Company's profile on SEDAR at www.sedar.com on or before March 31, 2023.
Mineral Resources Update
Advancing Lundin Gold's strategy of replacing production, M&I Resources are reported at 23.0 Mt with an average grade of 9.20 g/t containing 6.8 Moz of gold, including a total of 9.3 Mt with an average grade of 12.09 g/t containing 3.6 Moz of gold now categorized as Measured Resources, the result of improved confidence of the deposit geology, in part due to the operational maturity of FDN (see Figure 2).
The Company's estimate of Inferred Resources totals 9.2 Mt with an average grade of 5.64 g/t containing 1.7 Moz of gold. The Company is planning to carry out additional conversion drilling in 2023 and 2024 targeting the remaining 1.7 Moz of Inferred Resources. Through this drilling, the Company will endeavour to recategorize these Resources and eventually add to Mineral Reserves. These Inferred Resources are located primarily in the Southern area as well as some to the North.

Mineral Reserves Update
With this updated estimate, Lundin Gold has more than replaced depletion of approximating 1.38 Moz of gold from mining activities since the beginning of operations at FDN two and a half years ago. Results from the conversion drilling program have contributed to an improved understanding of the strong geological and grade continuity at FDN allowing for the inclusion of 3.4 Moz in the Proven Reserve category. Proven and Probable Reserves for FDN are reported at 18.0 Mt with an average grade of 8.68 g/t containing 5.0 Moz of gold, an increase of approximately 4.2% from the 2016 estimate.
