TheNewswire - September 21, 2021 - Avrupa Minerals Ltd. (TSXV:AVU) (OTC:  AVPMF) (FSE:8AM) is pleased to report that drilling continues to expand and upgrade polymetallic, massive sulfide mineralization at the Sesmarias Copper-Zinc Prospect within the Alvalade Project (Alentejo, Portugal).  The program is a joint venture between Avrupa Minerals and Minas de Aguas Teñidas, S.A. (MATSA) and is operated by Avrupa through the JV entity PorMining Lda.  To date, the Company has completed 11 diamond drill holes on six different fences, totaling 5,862 meters, and is drilling a 12th hole testing potential massive sulfide mineralization on Section 0350S.

Paul W. Kuhn, President and CEO of Avrupa Minerals, commented, "With continued drilling in the SES North sector, we have now intersected significant massive sulfide mineralization over 350 meters in strike length to the southeast from previously-reported intersections in SES21-033 and 036.  The SES21-039 intercept is the longest, to date, in the joint venture, and shows improving copper, zinc, and gold grades, as we move south along the strike of massive sulfide mineralization originally discovered in SES008.  The SES21-040 intercept contains the best copper results, to date, with 11 meters of 1.05% copper within a longer interval of polymetallic mineralization.  As we move south towards the SES Central (Discovery) sector, we look forward to the potential of continued improvement of grades."

SES North Results and Sections

To date, the Company completed ten drill holes in the SES North sector during this phase of drilling (SES20-031 through SES21-040), and one further hole in the SES Central sector (SES21-041), totaling 5,862 meters.  The Company reports results for SES21-037 through 040 in this release.

Drilling at SES21-042 is now underway on the 350 S section to test for possible mineralization above SES21-040.  Following the completion of SES21-042, the Company plans to drill further on the 350 S section to test for potential downdip massive sulfide mineralization below the SES21-040 intercept.  That hole will be collared approximately 40 meters northeast of the SES21-040 location.

Through all phases of drilling and exploration at Sesmarias, the Company has drilled copper-zinc massive sulfide mineralization in various lenses over a strike length of 1.7 kilometers.  Through interpretation of various programs of geophysical work and re-logging of historical drilling in the district, including holes with massive sulfide mineralization present, the strike length for possible massive sulfide mineralization may easily be extended to the north for a further 800-1000 meters.  All indications suggest that potential for further mineralization to the south is open, as well.  For now, the Company will continue to work on extending and upgrading the mineralization at SES North towards the SES Central sector, as well as defining massive sulfide occurrence in the Central sector.

Through detailed logging of the new core from this phase of drilling, as well as detailed re-logging of all the Sesmarias area historic core, we have established that the Sesmarias massive sulfide system is heavily folded and strongly modified by several phases of post-mineralization faulting.   However, through all this structural modification, the Company continues to intersect the target mineral horizon in all of the Sesmarias drilling.  The identification and separation of the different lenses of massive sulfide mineralization is strictly related to the location of mineralization on a specific limb of successive and adjacent folds (see sections below).  This supports the previous identification of the 2 Lens, the 8 Lens, the 10 Lens, and others at Sesmarias, as they are situated on different fold limbs and will project to the surface as separate lenses.  This geometry explains the historic situation of the numerous massive sulfide lenses that make up the Lousal deposit, just seven kilometers north of Sesmarias.  We expect a similar targeting story for Monte da Bela Vista, a further 2 kilometers beyond Lousal, as the complicated geology in all three target areas appears to be similar, if not directly related.

Surface expression of the 8 Lens Target Zone (red dashed lines) and projected surface expression of mineralization in the SES North sector.  Drilling is underway on the Section 350 S, where we have discovered a new lens (in purple) for the northern sector with significantly higher copper grade than previous holes in the northern sector.

Section 000 :  Simplified geological section, showing massive sulfides and stockwork zone in SES008, SES21-033, SES21-036, and SES21-037.   While the section shows the apparent bottom of the 8 Lens, further work to potentially open up the mineral horizon below SES21-037 and expand downdip will be contemplated in the future.  However, at this time, new drilling will be concentrated towards the south where copper and zinc grades appear to be rising and the size of the lens appears to be increasing.
