CD-054 assays 16.5m @ 7.2 g/t Au, 1.0% Cu, 4.1g/t Ag from 45.1m
LONDON, Sept. 13, 2021 /CNW/ - Meridian Mining UK S (TSXV: MNO) (Frankfurt: 2MM) (OTCQB: MRRDF) ("Meridian" or the "Company") is pleased to report further significant high grade gold mineralization from the Cabaçal Northwest Extension ("CNWE") as part of its maiden ongoing drill-program. The CNWE is part of the Cabaçal Copper-Gold Project ("Cabaçal") in Mato Grosso, Brazil
Within the CNWE, 410m to the Southeast of CD-049 (which intercepted 26.7m @ 21.5g/t Au), CD-054 has drilled a high-grade gold structure that returned 16.5m @ 7.2 g/t Au from 45.1m (Figure 1), part of a broader intersection of 54.4m @ 2.6g/t Au, 0.4% Cu, 1.7g/t Ag from 44.6m. CD-054 is an infill angled hole within the CNWE, located 200m from the Northwest limits of the Cabaçal Mine. Further drill results for the CNWE are pending and an expansion to the angled drill program along and beyond the CNWE is underway.
In addition, the Company today reports results from a preliminary inspection of CD-065, a 550m Southeast step-out from the Cabaçal Mine. A sulphide assemblage was intersected from 94.0m to 134.0m that included visual gold; XRF analysis confirms that a prospective sulphide assemblage is present.
Highlights of today's update:
- Meridian CD-054's assays significant gold mineralization of 16.5m @ 7.2 g/t Au at Cabaçal Northwest Extension;
- Meridian reports CD-054, returns 54.4m @ 2.6g/t Au, 0.4% Cu & 1.7g/t Ag from 44.6m;
- Peak assays include 102.6 g/t Au over 0.45m from 50.85m (Sample CBDS06272), and 70.7 g/t Au over 0.45m from 49.2m (CBDS06270);
- Cabaçal's 1,300m Copper-Gold-Silver trend confirmed - remains open;
- Multiple sub-vertical high grade gold structures intercepted within broad copper-gold-silver mineralization; and
- CD-065 intersects sulphide mineralization with visible gold 500m Southeast of Cabaçal.
"With CD-054's result and last weeks drill results, the CNWE trend joins with the Cabaçal mine area to form an open 1,300m trend that has unlocked huge potential for an open pit development scenario", commented Dr Adrian McArthur, CEO and President. Its high-grade core of 16.5m @ 7.2 g/t Au from 45.1m lies within a broader mineralized package of 54.4m @ 2.6g/t Au, 0.4% Cu & 1.7g/t Ag from 44.6m". This is very similar to CD-049's high grade gold core within a broad copper-gold-silver host, and similar to the high-grade structures exploited by BP Minerals ("BP") and Rio Tinto at the Cabaçal Mine within the broad VMS copper-gold envelope. Southeast of the mine the sulphides and visible gold from CD-065 is a great surprise and will be followed up. The program now is to drill out the CNWE and more results will be coming in the weeks ahead".

Cabaçal Northwest Extension
The CNWE is a 750m high-grade gold trend hosted within Cabaçal's now 1,300m VMS type Cu-Au-Ag mineralization, extending out from the Cabaçal mine. It is defined by an open Northwest trending gold soil anomaly and sparsely covered by BP's historical drilling. BP's drill holes were predominantly vertical and poorly suited to intersect the subvertical high-grade gold and Northwest trending structures mapped in the Cabaçal mine. CD-049 recently intersected multiple high-grade gold structures, more of these Northwest trending structures may be present to the Northeast and Southwest of CD-049.
CD-054 has now similarly intersected broad Cu-Au-Ag mineralization characteristic of the mine's Cu-Au-Ag +Zn stratigraphy, returning 54.4m @ 2.6g/t Au, 0.4% Cu, 1.7g/t Ag from 44.6m (Table 1). Within this, there is a higher grade Au zone of returning 16.5m @ 7.2 g/t Au from 45.1m. An angled infill drill program is planned for all of the CNWE to cover the open high-grade gold results of CD-049, CD-046 and beyond. The CNWE is up-dip to the Cabaçal West target currently being tested.
Cabaçal Southeast Extension
The Company stepped-out the drilling South-eastwards of the Cabaçal mine with CD-065, targeting an area where historical drilling indicated the presence of sulphide mineralization. Hole CD-065 is located 500m southeast of the Cabaçal mine. From 94.0m to 134.0m CD-065 intersected disseminated and locally stringer sulphide mineralization (pyrite-pyrrhotite-chalcopyrite) with visible gold at 132.0m (Figure 2). A Cabaçal type mineral assemblage was indicated by portable XRF2. The extent of the gold mineralization requires confirmation by assay, but the Company is encouraged to see the footprint of the Cabaçal system extending a significant distance to the Southeast.
Portable XRF readings are point-source readings, with width and grade to be confirmed by sample preparation and analysis at a certified laboratory.

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 are conducted by FAA505 and FAA525 (fire assay of a 50g charge), and base metal analysis by methods ICP40B and ICP40B_S (four acid digest with ICP-OES finish). Samples are held in the company's 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 control samples, including blanks and gold and polymetallic standards supplied by ITAK and OREAS, supplementing laboratory quality control procedures. True widths are interpreted to be ~80% of intersection widths. Assay figures and intervals rounded to 1 decimal place.
Samples for historical Cabaçal drill programs were analysed by for gold by 50g Fire Assay with AAS finish, copper three-acid-digest and AA finish, and silver by Aqua Regia by AA finish at BP Mineral's laboratory at Bonsucesso (Rio de Janeiro, Brazil), Samples were prepared at Caxias and the mine site itself. Half–core was dried, crushed to a quarter inch size through a jaw crusher, pulverised to 150 mesh in a ring mill, passed through a Jones Splitter to produce a 100–200g split, with one sample archived for reference and the other dispatched for analysis. BP Mineral's quality control program included duplicate analyses, and periodic checks using independent laboratories.
The "gold counts" referenced in the soil geochemistry figure is a measure of the number of gold grains visually counted in a pan concentrate from a set volume of material: a 5-litre bucket of soil from the B-horizon, providing a qualitative indicator of the presence of gold in a sample.
Meridian Mining UK S is focused on the acquisition, exploration, and development activities in Brazil.
