Significant Upside Unlocked in High Grade Gold Trend at Cabaçal Northwest Extension
/NOT FOR DISTRIBUTION TO U.S. NEWS WIRE SERVICES OR FOR DISSEMINATION IN THE U.S./
LONDON, Sept. 7, 2021 /CNW/ - Meridian Mining UK S (TSXV: MNO) (Frankfurt: 2MM) (OTCQB: MRRDF) ("Meridian" or the "Company") is pleased to report a significant high grade gold intercept from the Cabaçal Northwest Extension ("CNWE"). CNWE is part of the Cabaçal Copper-Gold Project ("Cabaçal") in Mato Grosso, Brazil. CD-049 intercepted a high-grade gold structure that returned 26.7m @ 21.5g/t Au from 66m (Figure 1). CD-049 extends the strike of the high grade gold intercepts to 150m, being a 100m step out from CD-0461, that intercepted a high-grade gold zone of 11.7m @ 5.7 g/t Au including 0.3 @ 183.4 g/t Au, and a 150m step out from BP Minerals diamond drill hole JUSPD216 that reported2 3.2m @ 237.7g/t Au, including 0.45m @ 1672.1 g/t Au. These high grade gold intercepts, open to the Northwest and Southeast, are part of the open "750m gold in soil anomaly" that trends Northwest. These significant results also support the possibility that to the Northeast and to the Southwest of the CNWE's trending high grade gold zone (Figure 2), parallel repeat high grade gold structures may exist as they did in the Cabaçal gold mine. The Company considers these parallel areas to be open and highly prospective and will be the focus of follow up exploration work.
Highlights of today's update:
- Meridian assays significant gold mineralization of 26.7m @ 21.5 g/t Au at Cabaçal Northwest Extension;
- Peak assay in CD-049 returned 377.6 g/t Au over 0.65m from 87.35 (Sample CBDS06049).
This sample is one of four samples grading over 100g/t, with others being:
- 123.1 g/t Au over 0.7m from 83.0m (CBDS06043);
- 137.2 g/t Au over 1.0m from 85.0m (CBDS06046);
- 127.3 g/t Au over 0.5m from 86.0m (CBDS06047);
- Continuous high grade gold core zone in CD-049 graded 8.0m @ 71.3g/t Au from 83.0m;
- High grade structure is open to the Northwest and Southeast;
- Possibility of parallel gold hosting structures with comparable mineralization; and
- Peak copper and silver assays are 2.0% and 19.1g/t respectively3, part of a broad 53.7m interval that graded 10.8g/t Au, 0.3% Cu and 1.3g/t Ag from 39.0m (Table 1);
Including a higher grade copper zone of:
- 10.7m @ 0.7% Cu, 0.4g/t Au, 1.9g/t Ag from 50.0m.
"CD-049's 26.7m @ 21.5 g/t Au is an outstanding high grade gold result from the Cabaçal Northwest Extension delivered by Meridian's team in Brazil", commented Dr Adrian McArthur, CEO and President. "This 100m "along strike step-out" from CD-046's intersection of 11.7m @ 5.7 g/t Au, itself a 50m "along strike step-out" from JUSPD216's 3.2m @ 237.7g/t Au is defining a high-grade gold trend within the Cabaçal Northwest Extension that remains open. This is a major turning point for the project and the Company. My congratulations to the exploration and administrative team, and thanks to our supportive investors in achieving this result today".

Cabaçal Northwest Extension
The CNWE is a 750m corridor of Cu and Au in soil anomaly associated with a prominent Northwest-trending strike ridge extending along the trend of the Cabaçal mine workings. The areas to the Northwest, Northeast, Southeast and Southwest of this high-grade gold trend and associated gold soil anomaly were sparsely covered by previous drilling, with a broad 100m reconnaissance pattern that was never infilled by resource definition drilling by BP Minerals.
The vertical drill holes were designed to cut the shallow-dipping VMS Cu-Au-Ag stratigraphy at a high angle. These holes are now known to be poorly suited to intersect the high grade subvertical gold structures that were formerly mined, and that extend out from the Cabaçal mine. Meridian's drilling program in areas extending from the Cabaçal mine, has purposefully drilled angled holes to intersect these high grade gold structures; resulting in today's result.

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 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.
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 true width of the CD-049 intersection is approximately 80% of the downhole length and assay figures and intervals rounded to 1 decimal place.
