Meridian Drills 46.0m @ 1.0% CuEq and Provides Cabaçal Exploration Update
(firmenpresse) -
Multiple high grade layers of Cu-Au mineralisation including 9.9m (at) 3.3% CuEq assayed
LONDON, United Kingdom, June 28, 2021 / CNW / Meridian Mining UK S (TSXV: MNO) (Frankfurt: 2MM) (Meridian or the Company) is pleased to report further assays from its ongoing 10,000m drill program at its Cabaçal Copper-Gold camp-scale VMS project (Cabaçal) in Mato Grosso, Brazil. Further wide zones of significant and extensive Copper (Cu), Gold (Au) and Silver (Ag) mineralisation starting at 9m, and with individual aggregated mineralisation intercepts exceeding 110m, are reported for holes CD-014 to CD-019 (Table 1), within and extending out from the Cabaçal Mine (Figure 1). Encouragingly, several results such as CD-017 returned broader than expected envelopes of mineralization, providing potential upside to future resource calculations where historic holes have been selectively sampled down hole. Meridian is also announcing the field deployment of its modern and deep penetrating Electromagnetic (EM) equipment with surveys in progress over the priority 1,000m long VTEM conductors of Cabaçal West and then progressing to Cabaçal Souths conductive corridor, extending out from the Cabaçal mines historical limits.
Highlights of todays results:
- Meridian drills multiple zones of high grade copper gold mineralisation at Cabaçal;
- 30.0m, 40.0m and 60.0m wide intervals of strong Cu-Au mineralisation drilled at Cabaçal;
- CD-017 returned 46.0m (at) 1.0% CuEq from 29.0m, including:
o 9.6m (at) 3.3% CuEq from 56.0m;
- CD-019 returned 62.5m (at) 0.6% CuEq from 12.0m, including:
o 2.5m (at) 3.1% CuEq from 20.7m;
o 2.2m (at) 3.5% CuEq from 53.5m;
- 17.2m (at) 1.2% CuEq from 130m;
- Total aggregate mineralisation was 110.7m (at) 0.6% CuEq from 12.0m;
- CD-015 returned an aggregate 46.0m (at) 0.8% CuEq from 40.7m, including:
o 6.1m (at) 1.0% CuEq from 67.2m; and
o 4.5m (at) 3.0% CuEq from 77.9m
- CD-016 returned 26.0m (at) 0.5% CuEq from 42.5m.
- CD-014* returned 20.5m (at) 0.8% CuEq from 54.0m; including:
o 6.8m (at) 1.2% CuEq from 55.6m;
o 3.3m (at) 1.0% CuEq from 69.2m; and
- CD-018* returned 14.2m (at) 0.4% CuEq from 9m.
Further results from Cabaçal will be released throughout 2021 supported by the Companys strong cash-on-hand position of CAD ~5.0M.
1 Note: True widths are CD-014 to 018 are approximately 90% of downhole lengths and assay figures and intervals rounded to 1 decimal place; the true width for CD-019 is approximately 75% of downhole lengths. 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.
Todays high grade drill results starting at shallow depths are important in highlighting the excellent open-pit geometry that Cabaçal presents. commented Dr Adrian McArthur, CEO and President. These results also really surprised us by defining thick shallow layers of Cu-Au-Ag mineralisation next to BPs drill results, but at intervals they didnt assay. A common occurrence in the 1980s when full sampling of core wasnt the norm. Our ongoing drilling is including a proportion of verification targets but is also carefully targeting positions where data is sparse; outside of the mines limits. We have also launched the exciting next stage of geophysical surveys using our own modern IP & EM equipment, that now is in the field. EM surveys have been initiated to map the down plunge cluster of Cabaçal West VTEM conductors interpreted to be the potential massive sulphide pile of Cabaçal. Then the EM surveys will continue SE, out from CD-004 that returned 15.9m (at) 4.0% CuEq.
The Companys program is advancing, with a combination of twin and infill Diamond Drill Holes (DDH) straddling the Eastern-Copper Zone (ECZ), Central-Copper-Zone (CCZ) and Southern-Copper-Zone (SCZ). Over 4,800m of drilling has been completed to date.
Central Copper Zone Results
CD-014 was designed to test Cu-Au mineralisation (and collared) proximal to BP Minerals historical DDH (BP) JUSPD048 that returned 20.1m (at) 0.3% Cu, 0.0g/t Au from 22m, 17.6m (at) 0.3% Cu, 0.1g/t Au from 47.4m; 40.9m (at) 0.7% Cu, 0.6g/t Au from 68.4m).

CD-014 struck a void from 75.1m-78.5m; and was terminated without replicating the lower results of JUSPD048.
CD-015 was designed to twin to BPs JUSPD068, which historically returned 42.7m (at) 0.7% Cu, 0.5% Au from 43.8m in the CCZ. CD015 traversed a mining void between 52. 7 - 56.4m, and assays returned 20m (at) 0.2% Cu, 0.1g;t Au, 0.7g/t Ag from 12m, and an aggregate 46m (at) 0.4% Cu, 0.6g/t Au, 1.2g/t Ag from 37m Assigning mining void null grade and zero width.

Table 1 Highlighted assay results for CD-014 through to CD-019.
The mineralisation reported today is a consistent copper dominant sulphide assemblage, present as disseminated, stringer, brecciated zones with local semi-massive sulphides. The confirmation of broad intact mine sequence stratigraphy returning strong grades and presence of mineralization extending beyond the limits of historically sampled core is a positive development. This will further review of the database as further results emerge and possibly additional drilling targeted are areas where drill density and/or sample coverage are sparse. It will be important that all mineralization is represented, including copper-dominant mineralization of higher or lower grades that may been peripheral to the focus of BP-Minerals/Rio Tintos surface and underground drilling programs.

Notes
Holes have been drilled HQ through the saprolite and upper bedrock and reduced to NQ - mineralized intervals represent half NQ drill core. Samples 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). Silver is repeated by method AAS12E. Samples are held in the companys secure facilities until dispatch 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 controls samples, including blanks and gold and polymetallic standards supplied by ITAK, supplementing laboratory quality control procedures.
