VANCOUVER, BRITISH COLUMBIA--(Marketwired - May 12, 2014) -
Avrupa Minerals Ltd. (TSX-VENTURE:AVU)(FRANKFURT:8AM) is pleased to
announce results for the recently-completed drilling phase at the
Sesmarias location on the Alvalade Joint Venture project in the
Iberian Pyrite Belt of Portugal. The Alvalade project is operated
by Avrupa and funded by a wholly-owned subsidiary of Antofagasta
plc ("Antofagasta").
Avrupa and Antofagasta drilled eight holes in the Sesmarias
area, including seven in the immediate vicinity of the initial
Sesmarias massive sulfide intersection, for a total of 1,961 meters
in the general target area. Results of JV drilling clearly indicate
the potential for a large-scale mineralized system.
Ongoing review of historic drilling around the peripheries of
the present program supports this idea, and suggests an immediate
target area of over 2,500 meters in strike length for the next
phase of drilling. The following figures outline the Sesmarias
massive sulfide system target area. Key points to take from the
figures include:
- The large scale of the Sesmarias system, with
previously-documented sulfide mineralization around the peripheries
of the present target area;
- Comparison of the size of the potential Sesmarias system to the
size of the giant Neves-Corvo system, located 50 kilometers
southeast of Sesmarias and presently mined by Lundin Mining
Company;
- Historic drilling completely missed the actual target rock
package, leaving
- A 2,500-meter strike length of never-before-been drilled
target area at Sesmarias.

Important analytical results from sampling of massive,
semi-massive, and stockwork sulfide mineralization are summarized
in the table below. Four of the seven holes intersected massive
sulfide mineralization at variable depths below the surface.
Massive sulfide mineralization in three of those holes was sent to
the lab for geochemical analyses (SES002, SES006, and SES008). A
detailed in-house study of the SES003 massive sulfide
mineralization was completed using a hand-held XRF (x-ray
fluorescence) analytical tool, and XRF studies of SES004, SES005,
and SES007 are presently underway. The XRF results are considered
informative and scientifically supportive to the study and
interpretation of the Sesmarias system, but should not be confused
with analytical results obtained from an accredited assay
laboratory. The XRF study of SES003 indicated similar VMS
mineralization to that of SES002, which was approximately six
meters away at the intersection of mineralization at depth.
Geochemical and geological results from all the work, to date,
indicate that massive sulfide mineralization at Sesmarias is hosted
within a specific package of black shale rocks located within the
general volcanic-sedimentary rock sequence where mineralization in
the Pyrite Belt is typically found. The sulfide mineralization is
fault-bound at both the upper and lower boundaries, suggesting that
mineralization could be cut-off and moved laterally along strike,
and/or vertically along dip, making exploration and delineation of
a potential deposit difficult. However, successful identification
of the target host package in this phase of the drilling is a
significant and positive step forward for exploration in the
Sesmarias area, and for other target locations within the Alvalade
Joint Venture license.

Plans for the next phase of exploration include 2,700 to 3,000
meters of drilling, with the first part of the program planned for
potential extension of the Sesmarias system in both northwest and
southeast directions, as well as for in-fill drilling between the
SES006 and SES008 drill holes. This drilling program will commence
in early June and should be completed in August, 2014.
Paul W. Kuhn, President and CEO of Avrupa Minerals, commented:
"We are extremely excited about the Sesmarias potential. It appears
possible that the Sesmarias area can host a large mineralization
system, containing valuable concentrations of copper, zinc, lead,
and silver, and potentially local concentrations of gold, tin, and
cobalt. Further work is clearly justified, and Antofagasta has
stepped up to fund further progress for the exploration program at
Sesmarias, and on the Alvalade Project in general. We are looking
forward to the startup of the next phase of drilling, scheduled for
mid-June."
Notes on analytical methods and quality control. All samples
were sent to the ALS Minerals sample preparation facility in
Seville, Spain. ALS shipped the prepped material to their main
European analytical laboratory located in Loughrea, Ireland. In the
main massive sulfide zones, total copper, silver, lead, zinc, and
cobalt results were obtained using a metals' extraction method
developed specifically for analysis of massive sulfide
mineralization. This includes metals' digestion by strong oxidizing
agents, followed by analysis using the industry-standard technique
of inductively coupled plasma - atomic emission spectroscopy
(ICP-AES). Total tin results were obtained using a lithium borate
fusion with the addition of a strong oxidizing agent, and followed
by x-ray fluorescence (XRF) analysis, performed in the ALS Minerals
laboratory located in Vancouver, Canada. In the lower anomalous
zone of SES002, all metals' results were obtained using a four-acid
digestion, followed by ICP-AES analysis for near-total results in
all metals, with the exception of tin, which was not re-analyzed
due to low levels. In addition to ALS Minerals quality
assurance/quality control (QA/QC) of all work orders, the Joint
Venture conducted its own standard, internal QA/QC from results
generated by the systematic inclusion of certified reference
materials, blank samples, and field duplicate samples. The
analytical results from the quality control samples in the
Sesmarias work orders have been evaluated, and conform to industry
best-practice standards.
