Vancouver, BC TheNewswire February 21, 2024 - Avrupa Minerals Ltd. (AVU:TSXV) is pleased to report on its progress during 2023 on programs in Portugal, Kosovo, and Finland, as well as comment on expected programs for 2024. The Company's projects in Kosovo and Portugal are fully-funded by Joint Venture partners. The Company is seeking a potential joint venture entity for its program(s) in the Vihanti-Pyhäsalmi VMS District, Central Finland.
Paul W. Kuhn, President and CEO of Avrupa Minerals ("AVU" or "Company"), noted, "Strong progress in deposit definition work at the Sesmarias copper-zinc-lead Project in Portugal during 2023 will be the underpinning for an aggressive drilling program in the SES Central Zone starting in Q2 2024.
After a successful PEA and Mineral Resource Estimate upgrade at the Slivova Project in Kosovo during 2023, we are looking forward to further upgrade of the precious metal inventory in and around the deposit, itself, as well as continued progress in the ESG aspects of the Project.
In Finland, we acquired new massive sulfide licenses in a well-endowed mining district, defined new drilling targets at one former producer, discussed the potential of acquiring several other VMS base metal targets, and commenced search for viable joint venture partners to advance the program there."
Portugal
Drilling continued throughout the year around the Alvalade pre-exploitation license in several target areas, including Caveira South, Casas Novas, Lousal Northwest, Brejo, and Sesmarias. The Company drilled 14 holes totaling 6,530 meters in 2023: two at Caveira South, one at Casas Novas, four in the Lousal Northwest area, one at Brejo, and six in the Sesmarias massive sulfide VMS deposit area.

The highlight of the 2023 drilling program was the re-discovery of the high-grade copper-zinc-lead-silver mineralization at Sesmarias in SES23-047 (see AVU news release June 12, 2023 ). Follow-up drilling at Sesmarias confirmed potential for more high-grade massive sulfide and stockwork mineralization in the Central Zone at Sesmarias (see AVU news release November 28, 2023 ). The success of the Sesmarias drilling underlies potential for the next phase of drilling there, tentatively commencing in Q2 of 2024. This phase will be aimed at defining the high-grade mineralization located in/around the hinge of the Sesmarias Syncline, particularly along strike between the 250 South and 800 South section lines, noted in the figures below. Plans for the next phase are underway.
To enhance targeting at Sesmarias, The Company performed an IP-Resistivity survey at the end of 2023 covering Sesmarias Central and Northern Zones and the Brejo target area just north of Sesmarias. Results are presently under evaluation, particularly for the North area and for the Brejo area where we have less historic drilling information. The level of success in the coming phase of drilling will determine how best to move towards a mining license application which will be necessary in the first half of 2025.

Figure 3. Known massive sulfide mineralization at Sesmarias, open both north and south. Drilling in the upcoming phase will target potential high-grade mineralization in the Central Zone between 250 South and 800 South sections. Modeling and interpretation of accumulated data suggests that strong, polymetallic VMS mineralization is hosted in and close to the hinge of the Sesmarias Syncline. UTM Zone 29 (ED50).
Drilling in the northern target areas of the Alvalade license was less successful than at Sesmarias. Drilling intersected narrow lenses of polymetallic sulfide mineralization in both Caveira South drill holes and wispy, distal facies, replacement sulfide mineralization in the Casas Novas drill hole. We hope to do follow-up drilling in both areas at some point in the future, but there are no plans for this in the up-coming drilling phase. Drilling at Lousal Northwest intercepted the mineral horizon black shales, but no significant sulfide mineralization.
The Alvalade project is a joint venture between Avrupa Minerals and Minas de Aguas Teñidas, S.A. ("Sandfire MATSA" or "MATSA"). Avrupa continues to operate the project through the JV entity PorMining Lda., and MATSA continues to fund the exploration work.
Kosovo
Work continued at the Slivova gold-silver project in Kosovo during 2023, undertaken by partner Western Tethyan Resources, and supported by 70%-owner Ariana Resources. Highlights of the work included the completion of a NI 43-101 Preliminary Economic Assessment (PEA) study that included a significant mineral resources' upgrade (see AVU news releases July 17, 2023 and September 6, 2023 for further, detailed information and notes concerning QP sign-off).
Western Tethyan also commenced environmental and social baseline studies in the project area, committing to a strong and positive social relationship with the communities around the project area, and performed exploration rock and soil sampling around the license to help identify satellite deposits. The government issued trenching and drilling permits for this year, and Western Tethyan is in the midst of planning and budgeting for the 2024 program. Work planned, in addition to continued environmental and social licensing, includes trenching over several untested targets and exploration drilling outside of the main deposit in efforts to increase the mineral resources. Eventually, there may be some infill drilling completed in 2024, as well. We anticipate that Western Tethyan will perform the necessary work to reach the 51% ownership level of the license during 2024, as required by the JV agreement (see news release of May 9, 2023 ).
Finland
During 2023, Avrupa's 49%-held Akkerman Finland Oy (AFOy) continued to advance the exploration program in the Vihanti-Pyhäsalmi VMS District of central Finland. The joint venture now holds two exploration permits covering known massive sulfide deposits (Kangasjärvi and Hallaperä), an application over a massive sulfide deposit (Rauhala), and an exploration permit covering a massive sulfide target (Kolima) that has been approved by the mining bureau, but not yet issued due to appeals court handling of the process.
Basic exploration work, continued review of historic core and geophysical data, and modeling of SkyTEM data from the Kangasjärvi license suggest an outstanding un-drilled target close to the old Kangasjärvi Mine. The joint venture is making plans for drilling at the target in 2024. There are further SkyTEM anomalies that may rate drilling after planned exploration work during the up-coming field season.

AFOy officially acquired the Hallaperä exploration license in the past year. The license covers a known massive sulfide deposit discovered by Outokumpu in 1967. The deposit is 1,500 meters long and ranges from two to 18 meters thick. It remains open at depth below 200 meters from the surface. The most recent drilling, in 1990, cut 1.85 meters @ 1.72% Cu, 1.7 g/t Au, and 44 g/t Ag, with no further work completed since that time.

The Finnish mining bureau recently awarded an exploration permit to AFOy for another license covering a massive sulfide deposit near the historic Vihanti Mine. The Rauhala deposit was discovered in 1985 by the Finnish Geological Survey (GTK), and later worked by Outokumpu Oy. It measures nearly 600 meters long and 350 meters wide and averages about 2 meters thick, as presently known. Virtually no work on the deposit has been completed in the past 20-25 years.
