Avrupa Drills 5.5 Meters of Massive Sulfides, 650 Meters From Initial VMS Intercept at Sesmarias, Alvalade JV Project, Portugal

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.
