NEWS RELEASE

LUNDIN GOLD ANNOUNCES 2021 PRODUCTION GUIDANCE OF

380,000 TO 420,000 OUNCES OF GOLD AT FRUTA DEL NORTE

Mine and mill throughput expansion from 3,500 to 4,200 tonnes per day to be

completed in 2021 and Mineral Reserves increase to 5.4 million ounces

December 8, 2020 (Vancouver, Canada) Lundin Gold Inc. ("Lundin Gold" or the "Company")

(TSX: LUG ) (Nasdaq Stockholm: LUG) is pleased to announce its 2021 guidance , a 20%

expansion of the mine and mill throughput and an 8% increase in Mineral Reserves estimates

at its Fruta del Norte gold mine (“Fruta del Norte”) in Ecuador. All amounts are in U.S. dollars

unless otherwise indicated.

Highlights:

• 2021 production is estimated between 380,000 to 420,000 ounces (“oz”) based on an

average head grade of 10.4 grams per tonne (“g/t”) and an average gold recovery of

90%

• At a cost of $18.6 million, throughput expansion capital is projected to result in a 20%

increase in mine and mill production from 3,500 to 4,200 tonnes per day (“tpd”)

• Probable Mineral Reserves increase by 8% to 5.41 million oz at 8.1 g/t primarily as a

result of a change in mining method from Drift and Fill to Long Hole Stoping

“Less than one year after reaching commercial production, we are embarking on an expansion

of the mine and mill at Fruta del Norte. With this added gold production coming online in the

last quarter of 2021, we will increase the average annual gold production from 325,000 oz per

year to 340,000 oz per year over the life of mine,” said Ron Hochstein, President and CEO of

Lundin Gold. “Our increase in probable reserves demonstrates the further upside potential we

see in the ore body, and we anticipate adding even more to these estimates upon completion

of an underground drilling program which began last month. Fruta del Norte continues to be

one of the few multi-million ounce, high-grade gold assets in production.”

2021 Guidance

Gold production at Fruta del Norte for 202 1 is estimated to be between 380,000 to 420,000

ozs. Mill production is estimated at an average rate of 3,500 tpd until the fourth quarter when

production is planned to ramp up to 4,200 tpd following completion of the planned mill

expansion. The head grade is estimated to average 10.4 g/t, with variations expected during

the year as different sections of the ore body are mined. Average mill recovery for the year is

estimated at 90%.

All-in-Sustaining-Costs ("AISC")1 for 2021 are expected to range between $770 and $830 per

oz of gold sold. AISC for 202 1 reflects continuing COVID-19 costs, reaching steady -state

maintenance programs and high sustaining capital resulting from the comple tion of the first

and second raises of the tailings dam for the increased throughput and from other one-time

improvements at the mine site some of which had to be deferred this year due to COVID-19.

The Company has assumed that COVID-19 protocols at Fruta del Norte will remain in place

for the full year; which represents a cost of approximately $27 per oz.

Total sustaining capital is estimated at $32.6 million, of which $14.6 million is for tailings dam

construction, $5.4 million for a resource expansion drilling program, and $5.5 million for surface

infrastructure. The remainder is for underground infrastructure and technology and other

efficiency improvements and additional small projects in the plant and on surface.

In addition, the Company is planning to complete the South Ventilation Raise near the end of

the first quarter of next year, which is critical to achieving expansion mining rates. Lundin Gold

also expects to complete construction of the Zamora River bridge, the only remaining scope

of work under the original Project. These two projects have a combined cost of $9.5 million.

In 2021, Lundin Gold will also embark on a $1 1 million, 9,000 metre drilling program on two

high priority exploration targets in its portfolio of concessions, Barbasco and Puente-Princesa,

which are located along the Suarez Pull-Apart Basin approximately seven kilometres from

Fruta del Norte.

Throughput Expansion Study

The results of a recently completed internal expansion study confirm that a throughput rate of

4,200 tpd can be achieved at an estimated capital cost of $18.6 million. Based on these

positive results, the Company plans to commence c onstruction in the first quarter of 2021 ,

followed by the mine ramping production to 4,200 tpd in the third quarter and the mill in the

fourth quarter of 2021. It is anticipated that the expansion can be completed with minimal

disruption to operations and be funded by cash flow from operations.

The project entails the purchase of two 45 tonne mine haul trucks, one in 2021 and one in

2022, additional rougher flotation capacity, the installation of a third gravity concentrator, a

second concentrate filter press and a second tailings paste pump . Detailed engineering has

commenced and orders for the key pieces of equipment have been placed.

The throughput expansion modifications are expected to improve mill recoveries through the

addition of retention time in the flotation process of the plant.

The throughput expansion project is not expected to impact any of the undisturbed area around

the site and is within the scope of the Environmental and Social Impact Assessment for Fruta

del Norte approved by the Ecuadorian Government. The Company intends to notify the

Ecuadorian Ministry of Environment and Water this month in relation to the expansion plans.

Increase in Mineral Reserves

Due to chan ges in planned mining method , the Company has updated it s estimates of

Probable Mineral Reserves for Fruta del Norte (“2020 Reserve”) to 5.41 million oz, an increase

of 427,000 ozs compared to the 2019 year end reconcilation of Probabl e Mineral Reserves

presented in the Company’s Annual Information Form (the “AIF”), dated March 24, 2020. The

2020 Reserve, which is effective as of July 31, 2020, is as follows:

Table 1. Probable Mineral Reserves(1)

AIF(2)(3)(4)(5)(6) 2020 Reserve(2)(3)(4)(5)(6)

Mt 17.6 20.8

Au (g/t) 8.74 8.1

Au (Moz) 4.99 5.41

Ag (g/t) 12.1 11.8

Ag (Moz) 6.92 7.68

See “Additional Technical Information” below for further information on the 2020 Reserve.

The increase in the 2020 Reserve is primarily due to the conversion of a significant portion of

the sections of the ore body originally mined by Drift and Fill to Long Hole Stoping, based on

the good ground conditions experienced in the mine to date, which resulted in a slight increase

in dilution and decrease in average grade . There was no increase in estimates of Mineral

Resources for Fruta del Norte.

The new Life of Mine Plan , which is based on the 2020 Reserve and throughput expansion,

provides for a total of 4.8 million oz of gold production over a 14 year mine life to 2034. The

annual average gold production over the first five years (2021 – 2025) is estimated at 390,000

oz, and for the life of mine (2021 - 2034) is estimated at 340,000 oz.
