Multiple layers of high-grade Cu-Au-Ag up to 5.7% CuEq assayed at Cabaçal.
Meridian Mining UK S (TSX-V: MNO) (FSE: 2MM) is pleased to report further strong results from its ongoing 10,000m resource delineation program at its Cabaçal Copper-Gold camp scale VMS project in Mato Grosso, Brazil. Significant near-surface zones of Copper, Gold and Silver mineralization (Table 1) have been again assayed within and outside of the limits of the historical Cabaçal Mine, by holes CD-020 through to CD-025 (Figure 1). Multiple high-grade intervals continue to be intercepted from near surface to depths greater than 150m by the program to date; further results pending.
Highlights of today’s results:
|1 Note: True widths are approximately 90% of downhole lengths and assay figures and intervals rounded to 1 decimal place. 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 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 & Silver 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. Calculation of composites for CD-021, CD-022, CD-023, CD-025 assigns zero width and zero grade to mining voids intersected between 52.4 to 55.9m, 83.8 to 87.8m, 122.9 to 126.1m, and 123.2 to 124.6m respectively.|
“Meridian’s drill results continue to confirm the grades, prospectivity and excellent geometry of Cabaçal’s Cu-Au-Ag mineralization”, commented Dr Adrian McArthur, CEO and President. “The past selective mining of BP Minerals/Rio Tinto, left behind extensive tonnages and Meridian is now launching the first technical and infrastructure review via the Ausenco study, evaluating requirements for a future open pit operation. At the same time, Cabaçal’s camp scale blue-sky upside is now being defined via the evaluation of the historical exploration results in conjunction with the rollout of the Company’s Electromagnetic surface surveys. Meridian’s first geophysical results, like Cabaçal West, are highlighting multiple VMS targets. This mirrors the evolution of similar VMS camps like Canada’s Flin Flon field, where such targets drove discoveries that sustained production for decades. We look forward to additional results from the ongoing geophysical and drilling programs.
CD-020 and CD-021 were drilled in the ECZ where historical sampling results commenced within the mineralization envelope. Both encountered a broader halo of mineralization extending into areas previously unsampled areas (Figure 1 Bottom).
The wide interval of mineralization in CD-022 (76.4m @ 0.7% CuEq from 11.1m; CCZ) is a positive result – confirming a thick package of mineralization extending from near-surface to the west of the previously reported results of CD-013 and CD-019.
CD-023 to CD-025 were drilled as infill holes on an extension of the section on which CD-003 was drilled early in the program (Figure 2). Results confirm encouraging widths and grades of mineralization extending up-dip from CD-003’s intersection.
Dr. Adrian McArthur, B.Sc. Hons, PhD. FAusIMM., CEO and President of Meridian Mining as well as a Qualified Person as defined by National Instrument 43-101, has supervised the preparation of the technical information in this news release.
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). 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 controls samples, including blanks and gold and polymetallic standards supplied by ITAK, supplementing laboratory quality control procedures.
Meridian Mining UK S is focused on the acquisition, exploration and development activities in Brazil. The Company is currently focused on resource development of the Cabaçal VMS Copper-Gold project, exploration in the Jaurú & Araputanga Greenstone belts located in the state of Mato Grosso; exploring the Espigão polymetallic project and the Mirante da Serra manganese project in the State of Rondônia Brazil.
