Meridian Announces Filing of its PEA Technical Report for Cabaçal Gold‐Copper
Project, Brazil
LONDON, United Kingdom, April 3, 2023 Meridian Mining UK S (TSX: MNO), (Frankfurt/Tradegate:
2MM) (OTCQB: MRRDF) (“Meridian” or the “Company”) is pleased to announce that the Company has
filed an independent Preliminary Economic Assessment (“PEA”) technical report (the “Technical Report”)
for the Cabaçal gold‐copper deposit in Brazil (“Cabaçal” or the “Project”), in support of the Company’s
news release dated March 6, 2023, entitled: “Meridian Delivers Strong Economics for Cabaçal’s PEA: After‐
Tax NPV5 of USD 573 million, 58.4% IRR & 10.6 Month Payback”. There are no material differences
between the Technical Report from those in the news release.
Cabaçal 2023 PEA Highlights, as announced on March 6, 2023 : (All amounts are in United States Dollars
unless otherwise stated)
Base case after‐tax NPV5 of $573M (CAD1 $778M) and 58.4% IRR using $1,650/oz gold, $3.59/lb
copper, and $21.35/oz silver;
Spot case after‐tax NPV5 of $745M (CAD1 $1.01B) and 69.7% IRR using3 $1,841/oz gold, $4.13/lb
copper, and $21.35/oz silver;
High‐grade year 1 mill feed of 2.3 g/t gold and 0.29% copper which generates high after‐tax first
year free cash flow of $204M, leading to capital repayment in 10.6 months;
Average grade of 0.64 g/t gold and 0.31% copper over the life of mine ‐ which demonstrates the
efficiency of the flowsheet in recovering the gold, copper and silver;
Average annual gold equivalent production of 131,100 ounces at AISC of $670.70/oz AuEq2 for
years 1‐5;Total LOM (22.3 years) production of 1.02M ounces gold, 353 Mlbs of copper and 1.76M
ounces of silver;
Pre‐production CAPEX of $179.6M (CAD1 $244.1M);
Low life‐of‐mine strip ratio of 2.1:1;
After tax NPV5:CAPEX Ratio of 3.2:1; and
Significant potential for future economic optimization and project upside remains through
engineering optimizations, increased throughput and additional resources that could be identified
through the ongoing drill programs.
1 Exchange Rate USD/CAD of 1.35889.
2 Gold equivalents are calculated a s: AuEq(g/t) = (Au(g/t) * %Rec o v e r y ) + ( 1 . 4 9 2 * ( C u % * % R e c o v e r y ) ) + ( 0 . 0 1 3 * ( A g ( g / t ) *
%Recovery)), where:
(a) Au_recovery_ppm = 5.4368ln(Au_Grade_ppm)+88.856
(b) Cu_recovery_pct = 2.0006ln(Cu_Grade_pct)+94.686
(c) Ag_recovery_ppm = 13.342ln(Ag_Grade_ppm)+71.037
3 Recoveries based on 2022 metallurgical testwork on core submitted to SGS Lakefield.
4 Spot prices on London close on 1st March, 2023.
The Technical Report dated March 30, 2023, with an effective da te of March 1, 2023, entitled “Cabaçal
Gold‐Copper Project NI 43‐101 Technical Report and Preliminary Economic Assessment, Mato Grosso,
Brazil” may be found under the Company’s profile on SEDAR at www.sedar.com and is also available for

Readers are cautioned that the PEA is preliminary in nature and i s i n t e n d e d t o p r o v i d e a n i n i t i a l
assessment of the Cabaçal’s econo mic potential and development options. The PEA mine schedule and
economic assessment includes nume rous assumptions and is based on inferred mineral resources.
Inferred resources are considered too speculative geologically to have the economic considerations
applied to them that would enable them to be categorized as min eral reserves, and there is no certainty
that the PEA results will be realized. Mineral resources are no t mineral reserves and do not have
demonstrated economic viability. Additional exploration will be required to potentially upgrade the
classification of the inferred mineral resources to be considered in future advanced studies.

ABOUT MERIDIAN
Meridian Mining UK S is focused on the development and exploration of the advanced stage Cabaçal VMS
gold‐copper project, on regional scale exploration of the Cabaçal VMS belt, on exploration in the Jaurú &
Araputanga Greenstone belts (all located in the State of Mato G rosso, Brazil) and exploring the Espigão
polymetallic project in the State of Rondônia, Brazil. Cabaçal is a gold‐copper‐silver rich VMS deposit with
the potential to be a standalone mine within the 50km VMS belt. Cabaçal’s base and precious metal‐rich
mineralization is hosted by volcanogenic type, massive, semi‐ma ssive, stringer, and disseminated
sulphides within deformed metavolcanic‐sedimentary rocks. A later‐stage sub‐vertical gold overprint
event has emplaced high‐grade gold mineralization cross‐cutting the dipping VMS layers. The Cabaçal
Mineral Resource estimate consists of Indicated resources of 52.9 million tonnes at 0.6g/t gold, 0.3%
copper and 1.4g/t silver and Inferred resources of 10.3 million tonnes at 0.7g/t gold, 0.2% copper & 1.1g/t
silver (at a 0.3 g/t gold equivalent cut‐off grade), including a higher‐grade near‐surface zone supporting a
starter pit. The Preliminary Ec onomic Assessment technical rep ort (the “PEA Technical Report”) dated
March 30, 2023, entitled: "Cabaçal Gold‐Copper Project NI 43‐101 Technical Report and Preliminary
Economic Assessment, Mato Grosso , Brazil” outlines a base case after‐tax NPV5 of USD 573 million and
58.4% IRR from a pre‐production capital cost of USD 180 million , leading to capital repayment in 10.6
months (assuming metals price scenario of USD 1,650 per ounces of gold, USD 3.59 per pound of copper,
and USD 21.35 per ounce of silver). Cabaçal has a low All‐in‐Su staining‐Cost of USD 671 per ounce gold
equivalent for the first five years, driven by high metallurgic al recovery, a low life‐of‐mine strip ratio of
2.1:1, and the low operating cost environment of Brazil (see press release dated March 6, 2023). Readers
are encouraged to read the PEA Technical Report in its entirety. The PEA Technical Report may be found
