LONDON
,
May 11, 2022
/CNW/ - Meridian Mining UK S (TSX: MNO) (
Frankfurt
/Tradegate: 2MM)
(OTCQB: MRRDF), ("Meridian" or the "Company") is pleased to announce it has intersected the
strongest zone of layered gold mineralization with CD-128 returning multiple visible gold occurrences
between 70.2 to
73.3m
(Photo 1), within the Southern Copper Zone ("SCZ") hosted by a broad
package of copper-gold VMS mineralization. The Cabaçal Mine's historical data indicates, that some
of the copper-gold VMS layers included garnet-rich bands hosting visible gold which reported some
of the highest gold grades. Meridian is also reporting further results from the Cabaçal Northwest
Extension ("CNWE"). CD-110's gold only layer has assayed
31.3 m
@ 1.0g/t Au, 0.1% Cu from
20.2m
with a high-grade zone of
10.4m
@ 2.3g/t Au from
32.5m
. The CNWE's drilling continues
along and across strike, where further visible gold has been intersected by CD-127; assays are
pending (Figure 1). These results show good continuity of the western extensions to the CNWE's
newly defined gold trend. Drilling is ongoing with further results pending.
Highlights of today's announcement:
Meridian intersects strongest layer of visible gold within the Cabaçal Mine;
Infill drilling in the Cabaçal Mine returns new zone of abundant visible gold;
CD-128 returns strongest visible gold intersection from the Southern Copper Zone
("SCZ")
;
Multiple coarse gold intervals within copper-gold VMS layer between 70.2 to
73.3m
;
Garnet-host to mineralization historically noted to be one of the richest host rocks;
CNWE's western trend of gold overlaying copper-gold VMS mineralization extended further;
CD-110 assays confirm good continuity in new CNWE western structure;
CD-110 assays:

Dr
Adrian McArthur
, CEO and President of Meridian, comments: "Confirmation drilling has
delivered strong visual results from within the Cabaçal Mine's SCZ. CD-128 has cored a
particularly wide interval of abundant visible gold, which has been dispatched for priority analysis.
The visible gold's host unit included bands rich in the mineral garnet, which was historically noted
to be one of the richest units for hosting gold in the mine. The results continue to support our
expectation that significant high-grade copper-gold mineralization remains present in the mine
environment. The CNWE's resource drilling program continues to extend the footprint of the newly
defined western trend and its gold only layer. The
50m
spacing infill program of angled holes has
confirmed continuity in this trend, with CD-110's mineralization located between the robust
intersections of previously reported in CD-113 and CD-099. This gold only horizon again shows
signs of detachment from the flatter lying VMS host sequence which has local and more regional
implications in exploration for gold-dominant structures associated with the overprinting gold event.
With visible gold identified in CD-127 and assays pending, this trend is showing signs of growing
further along strike as infill drilling extends back towards the mine."

Cabaçal Drilling Update
Hole CD-128 drilled within the SCZ, an area with historical workings. Has intersected a strong zone
of mineralization with visible gold observed in multiple intervals between 70.2 to
73.3m
, within a
broader interval of stringer to disseminated sulphides above the basal felsic volcanic "TAC" unit
intersected at
109.5m
. The gold is in part of a different style than previously reported, being hosted
within a horizon with a marked concentration of the aluminous mineral garnet. This known garnet-
gold association has returned some of the highest historical gold assays from the Cabaçal Mine,
with peak grades of JUSPD111 (collared
115m
east-south-east of CD-128 returned) returning
1,182.4g/t Au over
1.04m
from
59.3m
. The lower part of the interval 70.2 to
73.3m
contained further
visible gold hosted by quartz-sulphide (chalcopyrite) veins and within the foliated mine sequence
units. This further confirms the Company's observations that within the Cabaçal Mine's limits,
significant high-grade copper-gold mineralization remained after mining ceased in 1991. Samples
have been dispatched with priority, with assays pending.

CNWE assay results
CD-110 reported today, is an infill hole located between the CD-099 and CD-113, and includes a
broad zone of gold mineralization, also hosted a sub-vertical overprinting structure. This gold interval
projects above the underlying VMS mineralization horizon. CD-110's results confirm good grade
continuity, returning:
31.3m
@ 0.7% CuEq (1.0g/t Au, 0.1% Cu & 0.2g/t Ag) from
20.2m
Including:
10.4m
@ 1.6% CuEq (2.3g/t Au & 0.1g/t Ag) from
32.5m
High grade-gold overprinting structure assays:
10.0g/t Au over
0.80m
from
34.2m
(sample: CBDS14660);
8.6g/t Au over
0.75m
from
37.65m
(sample: CBDS14665);
The results again confirm a wide footprint of mineralization extending beyond the narrow projection
previously modelled from the wide spaced vertical drilling. The lower VMS horizon reported
24.4m
@ 0.2% CuEq (0.1% Cu, 0.1g/t Au, 1g/t Ag, 0.4% Zn) from
53.7m
. There were signs of
strengthening zinc mineralization, with a peak assays of 4.2% Zn over
0.45m
(sample CBDS14688;
4.2% Zn, 0.1% Cu, 0.1g/t Au, 3.4g/t Ag, 0.4% Pb).
Results from ongoing resource definition drilling at Cabaçal continuing to extend upside potential for
the CNWE. The first results[1] from drill holes CD-113 and CD-099 in the western structure have
indicated potential for a strong new western trend and gold overprint. Infill drilling is continuing and
has already shown signs of further along strike extensions to this trend, with visible gold recorded in
the correlative sequence of CD-127 at a depth of
69.8m
within a broader package of altered mine-
sequence stratigraphy. CD-127 is collared
50m
south-east of CD-113, and
98m
southeast of CD-
110, and
147m
southeast of CD-099. The results show an expanding footprint to this second
structure with drilling remaining in progress.
CD108 – a CNWE cross-strike infill hole drilled further down-slope,
50m
to the southeast of CD-099.
This hole continued to intersect a mineralized copper-gold halo associated with the mineralized mine
sequence stratigraphy:
22.9m
@ 0.2% CuEq (0.2% Cu & 0.1g/t Ag) from
8.5m
; and
27.0m
@ 0.4% CuEq (0.2% Cu, 0.3g/t Au, 1.3g/t Ag & 0.1% Zn) from
36m
.
This position will also continue to be tested along strike. A peak assay of 1.5 g/t Au over
1m
from
40.0m
(CBDS14050) may be indicative of a structural position.

Notes
True widths are approximately 80-90% of downhole lengths and assay figures and intervals
rounded to 1 decimal place.
Holes are drilled HQ through the saprolite and upper bedrock and
then reduced to NQ – mineralized intervals represent half HQ or NQ drill core. Samples have been
analysed at the accredited ALS laboratory in
Lima
. Gold analyses have been conducted by Au-
AA23 (fire assay of a 30g charge with AAS finish). High-grade samples are repeated with a
gravimetric finish (Au-GRA21). Base metal analysis is by methods four-acid digestion and ICP-
AES finish (ME-ICP61a; Cu-OG62 for over-range samples). Samples are held in the Company's
secure facilities until dispatched and delivered by staff and commercial couriers to the laboratory.
The Company submits a range of quality control samples, including blanks and gold and
polymetallic standards supplied by ITAK and OREAS, supplementing laboratory quality control
procedures.
