March 7, 2022

/CNW/ - Meridian Mining UK S (TSXV: MNO), (

Frankfurt

/Tradegate:

2MM) (OTCQB: MRRDF), ("Meridian" or the "Company") is pleased to provide assay results from

CD-094

drilled at the Cabaçal copper-gold VMS project in

Mato Grosso, Brazil

("Cabaçal"). CD-

094 drilled through Cabaçal's mine sequence and intercepted some of the strongest intervals of

copper ("Cu") - gold ("Au") mineralization seen to date and is one of the few angled holes in the

central zone able to hit the over-printing sub vertical gold veins. The

64.3m

interval graded 1.9%

CuEq from

22.0m

and confirms that the vast majority of high-grade copper-gold mineralization

remained unmined at Cabaçal, and locally, the higher-grading gold overprint has been poorly defined

by historical drilling. Drilling is ongoing with assays pending.

* Note:

True widths are approximately 90% of downhole lengths and assay figures and intervals rounded to 1 decimal place. Copper Equivalents ("CuEq") have been calculated

using the formula CuEq = ((Cu%*Cu price 1% per tonne) + (Au ppm*Au price per g/t) + (Ag ppm*Ag price per g/t) + (Zn%*Zn price 1% per tonne)) / (Cu price 1 % per

tonne). Commodity Prices: Copper ("Cu") and Zinc ("Zn") prices from LME Official Settlement Price dated April 23, 2021 USD per Tonne: Cu = USD 9,545.50 and Zn = USD

2,802.50. Gold ("Au") & Silver ("Ag") prices from LBMA Precious Metal Prices USD per Troy ounce: Au = USD 1781.80 (PM) and Ag = USD 26.125 (Daily). The CuEq

values are for exploration purposes only and include no assumptions for metallurgical recovery.

Adrian McArthur

, CEO and President comments: "CD-094 is one of our best holes to date at

Cabaçal. It confirms that shallow high-grade copper-gold VMS-type mineralization extends out

from the historical workings, and that the historical "vertical" resource drilling poorly defined the

extent of the high-grade and sub-vertical gold overprint at Cabaçal. Today's and our previous

results, show that our "angled" drill program has been highly successful in intercepting the sub-

vertical high-grade gold veins overprinting the copper-gold VMS layers. These gold veins were not

included in the historical resource calculation

, being missed by the 1980's vertical drill programs.

CD-094 is part of Cabaçal's metallurgical drilling program, and all of its high-grade copper-gold

mineralization will be combined with Meridian's other drill results and the historical data in the

future resource calculation. Cabaçal's drill program has been extended by 15,000 metres to a total

of 25,000 metres and results will continue into the second and third quarter of 2022."

CD-094 was collared within the historical mine's limits (Figure 1) and followed the general pattern of

Cabaçal's VMS mineralization, with shallow copper-dominant layers passing down into deeper

copper-gold-silver bearing mineralization, locally overprinted by sub-vertical gold bearing structures.

Mineralization (Table 1) was encountered

22.0m

below CD-094's drill collar and assayed

64.3m

1.9% CuEq (0.7% Cu, 1.9g/t Au, 2.6g/t Ag), with the higher grade

19.9m

thick basal layer grading

5.5% CuEq (1.8% Cu, 6.0g/t Au & 7.7g/t Ag) from

66.5m

. CD-094 intersected disseminated to

stringer mineralization, included periodic breccia to semi-massive sulphide intervals and sub-vertical

auriferous structures.

The high-grade intersection is positioned beyond the historically mined areas and its underground

grade control "fan" drilling. Reports of the era note that limited platforms were available for localized

underground grade control, leaving potential for further multi-ounce gold extensions, like

CBDS11940's, to be defined with future infill drilling.

Further results reported today:

Hole CD-090 was collared in the ECZ and continued the success of shallow strong grading copper-

gold mineralization from shallow depths. Hole CD-086 was collared to the northwest of the mine's

limits and intercept the extension of the mine's copper-gold VMS layers. It also intercepted a

northwest trending high-grade gold structure that returned

Cabaçal Metallurgical Program

Meridian's metallurgical program is advancing and nearly completed. It has recovered mineralization

from Cabaçal's Northwest extension to the mine's Southeastern limits. The program has recovered

mineralization that represent the full range of Cabaçal's geological domains, of a copper-gold-silver

VMS mineralization overprinted by late-stage gold (including coarse gold) for the bench-scale

metallurgical test-work.

Results reported to date from the metallurgical program include:

CD-088:

66.1m

@ 1.0% CuEq (0.6% Cu, 0.6g/t Au & 1.2g/t Ag) from

14.1m

(CCZ)

;

CD-085:

86.2m

@ 0.5% CuEq (0.4% Cu, 0.1g/t Au & 0.9g/t Ag) from

21.0m

(CCZ)

;

CD-090:

25.2m

@ 0.9% CuEq (0.8% Cu, 0.2g/t Au & 2.4g/t Ag) from

29.2m

(ECZ); and

CD-094:

64.3m

@ 1.9% CuEq (0.7% Cu, 2.0g/t Au & 2.4g/t Ag) from

22.0m

(CCZ).

The Company is conducting additional tests with HQ core barrels providing larger diameter samples

in the Cabaçal environment, recognizing that larger diameter core may assist in better representing

the coarse high-grade gold population.

Espigão do Oeste Polymetallic Program

The Company will shortly commence gravity surveys across the Espigão do Oeste copper-gold

Polymetallic Project ("Espigão"), targeting Iron Oxide Copper Gold ("IOCG") type anomalies or

other geological domains. Extensive surficial copper and gold anomalies have been defined by the

Company's past programs. Espigão is a longer term target for the Company's copper-gold

programs.

Notes

Metallurgical holes CD-090 and CD-094 have been drilled HQ from surface. Samples represent

quarter HQ core, with a quarter left for reference and half maintained for metallurgical testwork.

CD-090 has been sampled as half NQ core. Results reported from CD-086 have been analysed at

the accredited SGS laboratory in

Belo Horizonte

. Gold analyses have been conducted by FAA505

(fire assay of a 50g charge), and base metal analysis by methods ICP40B and ICP40B_S (four

acid digest with ICP-OES finish). Visible gold intervals are sampled by metallic screen fire assay

method MET150-FAASCR. Results for CD-094 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. Pulps are retained for umpire

testwork, and ultimately returned to the Company for storage. The Company submits a range of

quality control samples, including blanks and gold and polymetallic standards supplied by ITAK

and OREAS. Quality control measures included the use of laboratory standards, blanks,

duplicates, and umpire laboratory checks.
