TORONTO, Feb. 10, 2022 /CNW/ - (TSX: LUN) (Nasdaq Stockholm: LUMI) Lundin Mining Corporation ("Lundin Mining" or the "Company") today announces the discovery of a new copper-gold mineralized system called Saúva, located approximately 15 kilometers north of the Chapada mine, in the State of Goiás, Brazil.
As part of Lundin Mining's ongoing exploration program aimed at increasing the Mineral Resource estimation at Chapada, diamond drilling was initiated at Saúva in the third quarter of 2021 within a recently acquired exploration concession (Figure 1). Initial drilling was designed to test for the source of a strong soil copper anomaly (>1,000 ppm Cu) that was located along strike from the previously identified Formiga prospect. The first two drill holes at Saúva confirmed the presence of shallow high-grade copper-gold mineralization. Further drilling was undertaken to evaluate the potential and to date a total of forty-seven (47) holes have been completed defining a mineralized area measuring approximately 750 meters by 650 meters, with assay results available for 29 holes (Table 1). The mineralization currently remains open in all directions.
Highlights from initial drilling include:
Hole FOR-113: 55.48 m at 0.88% Cu and 1.15 g/t Au or 1.72% CuEq1, from 6.52 m
including: 27.26 m at 1.30% Cu and 1.89 g/t Au or 2.68% CuEq, from 33.74 m
Hole FOR-115: 65.45 m at 0.61% Cu and 0.70 g/t Au or 1.12% CuEq, from 23.55 m
including: 18.41 m at 1.26% Cu and 1.92 g/t Au or 2.66% CuEq, from 50.43 m
Hole FOR-123: 64.25 m at 0.72% Cu and 1.10 g/t Au or 1.51% CuEq, from 158.45 m
including: 43.25 m at 0.90% Cu and 1.52 g/t Au or 2.01% CuEq, from 158.45 m
and: 70.40 m at 0.42% Cu and 0.11 g/t Au or 0.50% CuEq, from 248.70 m
including: 8.56 m at 1.04% Cu and 0.16 g/t Au or 1.16% CuEq, from 248.70 m
Hole FOR-135: 57.31 m at 0.79% Cu and 1.06 g/t Au or 1.56% CuEq, from 8.29 m
including: 17.95 m at 1.27% Cu and 1.98 g/t Au or 2.71% CuEq, from 32.05 m
and: 12.80 m at 0.44% Cu and 0.11 g/t Au or 0.52% CuEq, from 189.20 m
Hole FOR-148: 74.06 m at 0.81% Cu and 1.27 g/t Au or 1.74% CuEq, from 116.00 m
including: 19.39 m at 1.80% Cu and 3.61 g/t Au or 4.43% CuEq, from 149.61 m
Lundin Mining President and CEO, Peter Rockandel, commented "The shallow and high-grade copper-gold mineralization discovered at Saúva is a clear example of the growth optionality that stems from Lundin Mining's successful track record of aggressive near-mine and brownfields exploration at all of our operations. Implications that this new high-grade mineralized system may have for our on-going expansion studies of Chapada will be evaluated as this discovery evolves during the year."
Ciara Talbot, Vice President, Exploration, added "We are very pleased with this early-stage discovery within the exploration concessions identified and acquired as part of last year's federal auction process. This discovery supports our view that numerous opportunities exist to increase the size and quality of our Mineral Resource base at Chapada."

Saúva Discovery
In 2015, the Chapada exploration team identified the Formiga exploration target, approximately 15 km north of the mine, based on positive chip sampling and regional mapping. The first drill holes at Formiga intercepted skarn style alteration comprising hydrothermal assemblage of garnet-epidote-amphibole-diopside in metasedimentary rocks. Then, during soil sampling in the region in 2016, additional disseminated copper-gold targets in the Formiga sector were identified along strike in metadiorite with hydrothermal alteration similar to what is being mined at Chapada. This trend of mineralized occurrences appeared to extend off the exploration concession to the west.
Following the acquisition of Chapada by Lundin Mining in 2019, a Mineral Inventory Range Analysis study was undertaken to refine the exploration strategy, including the prioritization of potential mineral concession acquisitions ahead of the anticipated federal auction. In the first half of 2021, Lundin Mining acquired 37 new exploration concessions through the auction process, covering 58,048 hectares and increasing the total land position around the Chapada mine by over 120%. This included the concession immediately west of Formiga. Two initial drill holes, FOR-112 and FOR-113, were designed to test for the source of a strong soil copper anomaly (>1,000 ppm Cu) on this newly acquired concession along strike from Formiga. Both drill holes confirmed the presence of shallow high-grade copper-gold mineralization, which has become the Saúva prospect discovery.
Saúva Exploration Results
Following the initial discovery of the Saúva in September 2021, an aggressive exploration drilling campaign was commenced with five drill rigs to better define the potential size of the discovery. Forty-three (43) drill holes, totaling 12,850 meters, had been completed at Saúva as of December 2021. Almost all drill holes intercepted the mineralized layer containing high chalcopyrite with (±) bornite content and with the majority returning intersections with grades above 1.0% CuEq, confirming the potential for significant, shallow and high-grade copper-gold mineralization. The location of the drill hole collars are shown in Figures 2 and 3, along with an approximate outline of where mineralized horizons have been intersected. The mineralization continues to remain open in all directions.
Mineralization at Saúva is comprised of disseminated and vein-hosted bornite and chalcopyrite hosted by biotitic and quartz-feldspar altered rocks. The high-grade mineralization (>1.0% CuEq) is associated with bornite greater than chalcopyrite, or chalcopyrite greater than bornite sulfide zones. Lower grade mineralization (>0.3% CuEq) is associated with chalcopyrite and pyrite + chalcopyrite sulfide zones. A representative cross section of the mineralized horizons is presented in Figure 4. The hydrothermal alteration zone is currently interpreted to generally follow a northeast trend, but individual high-grade orientations vary and detailed modeling remains in progress.
2022 Exploration Program
Lundin Mining is evaluating and interpreting the results reported in Table 1 and continues to explore for extensions to the mineralization. There are presently three rigs drilling in the Saúva sector testing areas to the northeast and west of the discovery area. Aggressive and methodical exploration of the sector is planned for 2022 as part of the $10 million exploration program at Chapada. Additional drill rigs and approximately fifty (50) holes are planned to test northeast along strike to towards the Formiga sector, as well as step out in other directions, as seen in Figure 2.
Technical Information and Quality Assurance
The drill holes were collared at HQ diameter from soil to altered rock and changed to NQ when fresh rock was encountered. The drill rods were three meters long and the wireline core drilling method was employed. The majority of holes were drilled at an azimuth of 120° and a 70° dip, perpendicular to interpreted strike and the mineralized horizon. However, some holes were drilled at other orientations where ideal surface access was not possible at the time. Downhole surveys were taken by the drilling contractor upon completion of the drill hole. All drill holes were surveyed every three (3) meters downhole using a Reflex GYRO SPRINT-IQ™ electronic surveying instrument. Generally, the deviation was below 5%, and no significant deviation issues were found to date. Collar surveys were taken by GPS with CenterPoint RTX in UTM coordinates, SAD 69 Brazil datum, 22 South Zone. Drill hole collars were cased and protected at the surface with a cement block affixed with a metal tag stamped with the drill hole number, final depth, inclination, azimuth, and start and finish dates.
All Lundin Mining assay results from drilling have been independently monitored through a quality assurance/quality control ("QA/QC") program, including the insertion of blind standards, duplicates, blanks, and pulp and reject duplicate samples. The soil, saprolite, and altered rock were drilled from HQ size core and the fresh rock from NQ size core. Half of the core was collected, and the sample interval was around one (1) meter for mineralized zones and two (2) meters for non-mineralized zones. Quarter core samples were collected for duplicate analysis. The samples were securely transported by a locally based transport company from our core preparation facility at the Chapada Mine, Brazil to the ALS Chemex sample preparation facility in Goiania, Brazil. Sample pulps were sent for analysis to the same lab in Lima, Peru, which is independent of Lundin Mining. The samples were analyzed by fire assay/atomic absorption spectroscopy (AAS) (gold) and four acid digestion/ICP-MS (copper). The analysis was conducted by ALS Chemex Lima, Peru, accredited by the Standards Council of Canada ISO 17025:2005, and the secondary laboratory SGS GEOSOL, Vespasiano, Brazil accredited by ISO 9001:2008, both independent laboratories.

Notes:
| 1.
| Reported intercepts are not true thicknesses as there is currently insufficient data to calculate true orientation.
| 2.
| Copper equivalent grades (CuEq) are for comparative purposes only. Calculations are uncut and recovery is assumed to be 100% as metallurgical data is insufficient to allow for estimation of metal recoveries. Copper equivalence (CuEq %) is calculated as: CuEq % = Cu % + (Au g/t x 0.7292), employing metal prices of Cu – US$3.00/lb, Au – US$1,500/oz.
