CNWE's drills new intervals grading up to 70.1 g/t gold and 6.2 % copper

LONDON, UK / ACCESSWIRE / October 19, 2022 / Meridian Mining UK S (TSX:MNO)(Frankfurt/Tradegate:2MM)(OTCQB:MRRDF), ("Meridian" or the "Company") is pleased to report further assays from the Cabaçal gold-copper VMS deposit ("Table 1"). Down-dip resource drilling has intercepted new strong gold-copper trends within the CNWE area, while infill drilling has continued to confirm the high-grade near-surface gold trend within the Indicated Resource envelope, designed to enhance its level of confidence in the evaluation of high-grade starter pits. Today's results include a new copper enriched trend within Cabaçal's Northwest Extension ("CNWE") located outside of the current Cabaçal Resource¹ model ("Figure 1") with one of the new gold-copper zones also overprinted by a new high-grade open gold structure. Further assay results are pending.

      • Intervals of 6.0% Cu over 0.4m, 4.4% Cu over 0.35m and 3.8% Cu over 0.8m; and
• Assays results to be included in the 2023 Resource update. True widths are approximately 80-90% of downhole lengths

The separate gold-dominant and copper-enriched trends confirm the zonal aspect of the 1.9km Cabaçal VMS deposit. Consistent strong copper zones are generally concentrated in the south-east sector of the deposit, however new copper enriched lenses are emerging within the CNWE. The entire deposit is overprinted by a later stage high grade gold event.

Dr Adrian McArthur, CEO and President comments : "Today's results have identified new VMS high-grade gold rich zones and copper-gold layers and are very encouraging as these and future results will contribute to the 2023 resource update. These results have also opened the CNWE for another two corridors where the high-grade gold overprint is present. Having continual strong results at shallow depths support our views that the Cabaçal gold-copper deposit offers strong optionality in its early years for high-grade feed for rapid capital payback, backed by a larger resource. The Company plans to update the resource early in the second quarter of 2023, and in parallel continues with data compilation and evaluation of targets to prepare for expanded exploration programs targeting and unlocking the potential of the broader belt."

Cabaçal's Infill and Extensional Drill Program

The infill program of angled holes has been critical in defining high-grade gold trends plunging gently to the south that were previously not detected in the historical program. Whilst much of the CNWE is gold-dominant, the recent detection of higher-grade copper-dominant copper-gold mineralization in CD-193 and CD-171 suggests potential to yet define further higher-grade shoots of stringer copper sulphide mineralization plunging through this part of the VMS system.

The Company is focusing its future studies on the resource's higher-grade zone that is hosted within a coherent trend along the deposit's 1.9km strike length. Ongoing drilling has focussed on continuing the closure of the broad-spaced 100m historical drill sections and preparing the project for a full feasibility study. The Company intends to update the mineral resource estimate early in the second quarter of 2023.

The Company froze assay results for the Cabaçal database in mid-August, to commission a mineral resource estimate which was reported on September 26, 2022 . The Company's inaugural mineral resource estimate for Cabaçal delivered Indicated Resources hosting 1.1M ounces gold, 168.0 Kt of copper and 2.4M ounces of silver, and Inferred Resources hosting 0.2M ounces gold, 24.5 Kt of copper and 0.4M ounces of silver. The inaugural resource reflected the discovery of significant additional gold-dominant mineralization in the north-west extension during the infill and extensional drilling program, which resulted in a significant increase in known mineralization from historic estimates.

The objectives of the ongoing program are:

1. To complete an angled drilling pattern on a 50 x 50m grid to define the ultimate limits of economic mineralization and convert inferred resources to indicated resources;
2. To conduct further closure to a 25 x 25m pattern in select areas to increase confidence in shallow mineralization representing potential targets for higher-grade starter pits in development studies; and
3. To target select drilling into shallow resource areas where prior sampling was limited or absent and verify copper recovery in the oxide zone (currently set to zero).

Work continues on compilation and validation of the data for the shallow and high-grade Zn-Cu-Au-Ag Santa Helena deposit which will be targeted as the next resource development project following statutory approvals by the environmental agencies, along with evaluation of a range of high priority gold and copper exploration targets within the Cabaçal belt's C2 Trend³.

About Cabaçal

In November 2020, Meridian signed a Purchase Agreement to acquire 100% ownership certain tenements covering the historical Cabaçal and Santa Helena mines and the along strike tenements from two, private, Brazilian companies ("Vendors"). Subsequently, Meridian expanded its land tenure to today's 55km of strike length. Cabaçal had two historical, shallow, high-grade selectively mined underground mines that cumulatively produced ~34 million pounds of copper, ~170,108 ounces of gold, ~1,033,532 ounces of silver and ~103 million pounds of zinc via conventional flotation and gravity metallurgical processes.

Meridian has defined an open trend of shallow copper-gold mineralization centred on the Cabaçal Mine. This mineralization trends Northwest-Southeast, sub-crops along its Northeast limits and dips to the southwest at 26° and is up 90m thick; presenting excellent open-pit geometry and mineral endowment. Meridian is currently focused on infilling drilling along a 2,000m corridor along this trend.

Cabaçal's base and precious metal-rich mineralization is hosted by volcanogenic type, massive, semi-massive, stringer, and disseminated sulphides within units of deformed metavolcanic-sedimentary rocks ("VMS"). A later stage sub-vertical gold overprint event has emplaced high-grade gold mineralization truncating the dipping VMS layers. It was explored and developed by BP Minerals/Rio-Tinto from 1983 to 1991 and then by the Vendors in the mid 2000's. This historical exploration database includes over 83,000 metres of drilling, extensive regional mapping, soil surveys, metallurgy from production reports and both surface and airborne geophysics. The majority of Cabaçal's prospects remain to be tested.

Cabaçal has excellent infrastructure with access by all-weather road, industrial electricity provided by the adjacent hydroelectric power station supplying this clean energy grid, and local communities provide a large population to draw employees from. Cabaçal consists of 1 mining license, 1 mining lease application and 7 exploration claims which total 44,265 hectares. The September 2022 Cabaçal mineral resource estimate consists of Indicated resources of 52.9Mt @ 0.6g/t Au, 0.3% Cu and 1.4g/t Ag and Inferred resources of 9.0Mt @ 0.7g/t Au, 0.2% Cu & 1.1g/t Ag (0.3 g/t AuEq cut-off grade), with strong optionality for targeting higher grade mineralization using a 0.5 AuEq cut-off for the future development studies.

Drill holes have been 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 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. 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, supplementing laboratory quality control procedures. True widths are approximately 80-90% of downhole lengths and assay figures and intervals rounded to 1 decimal place.
