AVPMF - Avrupa Minerals Intersects 26.95 Meters @ 2.18% Copper 2.58% Lead 5.60% Zinc and 88.2 ppm Silver at Sesmarias Portugal
(TheNewswire)
-
Total mineralized drill intercept is43.40 meters at approximately 400 meters depth (see table below),though the true thickness is not known at this early stage;
-
Sesmarias discovery hole in 2014,SES002, intersected 7.95 meters of 2.21% copper, 3.05% lead, 4.82%zinc, and 89.8 g/t silver at approximately 150 meters depth, butsubsequent shallow follow-up drilling at that time failed to intersectfurther shallow mineralization;
-
Follow-up drilling, funded by earn-inpartner Sandfire MATSA, is underway, with 6 additional holesplanned.
Vancouver, BC – TheNewswire - June 12, 2023 – Avrupa Minerals Ltd. (TSXV:AVU) is pleased to provide new assay results from the Sesmariasmassive sulfide target area, Alvalade JV Project, Portugal. Theprogram is a joint venture between Avrupa Minerals (“AVU” or“Company”) and Minas de Aguas Teñidas, S.A. (“Sandfire MATSA”or “MATSA”). Avrupa continues to operate the project through theJV entity PorMining Lda., and MATSA continues to fund the explorationwork. Previously, through the JV, during 2020-2021, the Companydrilled 17 diamond drill holes, totaling 8,900 meters, on sixdifferent fences along a strike length of 400 meters in the SesmariasNorth Zone.
The JV returned to drilling at Sesmarias in mid-April,targeting the Central Zone, where Avrupa drilled the high-gradediscovery hole, SES002, in 2014 (see February 27, 2014 NewsRelease ). Follow-up drilling in theimmediate discovery area at that time unsuccessfully targeted shallowextensions of the mineralization seen in SES002 at a depth of about150 meters. Armed with a significantly upgraded targeting modelconstructed after a total of 46 holes and nearly 20,000 meters ofdrilling at Sesmarias since 2014, the JV geological team aimed deeperto 400 meters depth to attempt to locate further high-grademineralization.
Results from SES23-047 are:
-
26.95 meters of 2.18% copper; 2.58%lead; 5.60% zinc; and 88.2 g/t silver from 393.80 to 420.75 metersdepth, within a wider interval of:
-
43.40 meters of 1.51% copper; 2.15%lead; 4.78% zinc; and 64.1 g/t silver from 392.80 to 436.20 metersdepth.
At this time, with only one drill hole in the new zone,the true thickness of the massive sulfide mineralization is unknown. The drill hole intercepted at least part of the eastern limb of thetarget mineralized syncline, and possibly part of the hinge of thesyncline. Further drilling is clearly necessary to search for bothextension and shape of the mineral body. We are currently drilling afollow-up hole, collared approximately 150 meters southeast ofSES23-047, with five more holes planned, also funded by the JVpartner.
Paul W. Kuhn, President and CEO of Avrupa Mineralscommented, “We are truly excited about the SES23-047 results. Theentire team effort putting together a coherent targeting model led tothis initial success in the Sesmarias Central Zone, which we hope willcontinue with follow-up drilling. Previous JV drilling demonstratedthe potential for significant thicknesses of massive sulfidemineralization, and we recognized the potentialfor higher grade mineralization as we moved south towards the CentralZone, perhaps the center of the mineral system. We now recognizethat the SES002 lens should be part of the new discovery lens,separated by faulting. Perseverance, continued creative thinking,and strong financial support led to a real success that showspossibilities for further follow-up success.”
The following summary cross section demonstrates thepotential for further mineralization on this section line, in themiddle of the Central Zone.
Figure 1. SES23-047 cross section showing previous drilling anddiscovery hole SES002. The mineralized syncline seen here is acontinuation from the previously-reported, more northerly sectionsthat show development of an eastern overturned limb, a western normallimb, and development of a robust hinge zone. Further drilling iswarranted to develop a potential high grade central zone to thedeveloping system.
Potential for further higher-grade mineralization liesfrom the present 650S section to the 350S section, north of thepresent drilling, and possibly for another 300 to 400 meters to thesouth of the 650S section. We are presently drilling at SES23-048,collared approximately 150 SE of SES23-047, on the 800Ssection.

Note that the Central Zone appears to be open and untested for atleast 300 meters in either direction from the 650S section. Presently drilling on the 800S section line at SES23-048.
Results and information for SES21-044, Section 350S,may be found in the January 25, 2022 NewsRelease . Results and informationfor SES026, located approximately 350 meters SE of SES23-047 on the1000S section, may be found in the March 11, 2019 NewsRelease .
Notes on analytical methods andquality control. The JV analyzed themineralized material at two different laboratories, as the table belowdemonstrates. For certified, NI43-101 – acceptable assay results,we selected the ME-MS61 method performed by ALS Global at theirSeville sample preparation facility and Loughrea, Ireland analytical laboratory. For in-house reasons and desire tohave overnight results, we authorized preliminary analyticalprocedures at the non-certified, MATSA laboratory facilities at theAguas Teñidas Mine.

For technical reasons, at the depth of the Sesmariasmineral intersection, drillers had reduced core size to NQ (47.6 mmdiameter). Project personnel collected oriented drill core twicedaily from the drill rig and delivered the boxes directly to theProject core storage facilities in Grândola, Portugal. Here, aftergeological and geotechnical review of the core, a Project geologistmeasured and marked the core for sampling, with sample lengthaveraging one meter depending on visual factors such as change intexture, style of mineralization, and/or host rock type. Projectemployees systematically and methodically halvedthe core, utilizing an electric core saw, and then placed one half ofthe split material for each sample length into separate, numbered,plastic sample bags. In order to get fast, first-hand results,Project personnel transported the core samples to partner SandfireMATSA’s Aguas Teñidas Mine laboratory in Almonaster la Real, Spainfor preliminary, non-certified analytical information.
After acquiring the preliminary results, Projectpersonnel carried the sample pulps (-80 mesh material used formetals’ digestion) to the ALS Global (“ALS”) sample preparationfacility in Seville, Spain. ALS directly shipped the pulp materialto their main European analytical laboratory located in Loughrea,Ireland. At the analytical laboratory, we requested the samples tobe analyzed via the lab’s ME-MS61 technique which uses a four-acid,near-total metals’ extraction method, followed by analysis using theindustry-standard technique of inductively coupled plasma – atomicemission spectroscopy (ICP-AES).
At all times, prior to submission of the samples to ALSGlobal, Project or Sandfire MATSA personnel maintained supervision,oversight, and custody of the samples.
In addition to ALS Global in-house qualityassurance/quality control (QA/QC) for all work orders, the Projectconducted its own normal, internal QA/QC from results generated by thesystematic inclusion of certified reference materials, blank samplesand field duplicate samples. Project personnel reviewed and evaluatedthe analytical results from the quality control samples in theSES23-047 work orders, and confirmed that these results conform toindustry best practice standards.
