Drilling commences targeting high grade Cu-Au: Southern Copper Zone and Eastern Copper Zone
LONDON , March 16, 2021 /CNW/ - Meridian Mining UK S (TSXV: MNO) ("Meridian" or the "Company") today announces that the diamond drill and surface geophysical programs have commenced at its Cabaal Copper-Gold project in Mato Grosso Brazil (the "Project"). The first diamond drill hole ("DDH") CD-001, being drilled by Rig One, is adjacent to the historical BP Minerals hole of JUSPD 596 that intercepted extensive high grade copper gold mineralisation Figure 1. Rig Two is now collared adjacent to JUSPD 228 targeting an eastern extension to the high grade copper and gold zone of the shallower Easter Copper Zone .
Highlights of the exploration program's rollout
- Two diamond drill rigs turning
- First phase of the DDH program is to twin historical DDHs completed by BP Minerals/Rio Tinto;
- Rig One targeting JUSP 596 historical intersection of 13.4m @ 5.2% Cu, 2.7g/t Au, 9.5g/t Ag and 0.5% Zn 1 ;
- Rig Two targeting shallow high grade copper gold mineralisation of the Eastern Copper Zone with a target interval from 50 metres;
- Surface Electromagnetic ("EM") Surveys
- First surveys commenced on the zone south east of the Cabaal mine;
- Project first Bore-hole EM surveys on the Cabaal project to commence shortly;
- Company plans to upload to its website additional geological data from the 1990 Mason and Kerr report to provide additional technical information about the Project; and
- Meridian's balance sheet improved by $806,701 with the recent conversion of 7,447,120 Warrants.
The first phase of the drill programs has a pre-set selection of 15 drill targets. The first EM survey lines were undertaken last week in a zone to the South of the historic Cabaal mine workings. This program is targeting both high conductive mineralisation as well as more selective lower conductive anomalies associated with the disseminated sulphide type mineralisation typical of the Cabaal mine. The location and identification of the historical BP Minerals / Rio Tinto drill hole platforms and collars is ongoing and will play an important role in the validation of the geological database.
Rigs One and Two will be using HQ Core size barrels. The recovered DDH core is being logged and cut on-site at the Cabaal core shed located in the former now rehabilitated buildings of the former mine. Drill core analyses will be done by ALS, with preparation at their facilities at either Goinia or Belo Horizonte . Pulps will be sent to the ALS laboratory in Lima, Peru . Analytical methods will involve Cu-Ag-Zn-Pb analysis as part of a 33-element package ME-ICP61a, with over range elements by method (+)-OG62, involving four-acid digest and ICP-AES finish. Gold analysis will be conducted by method Au-AA23 involving fire assay and AAS finish, and over-range / high-grade values by Au-GRA21 (gold by fire assay and gravimetric finish). From time to time, SGS Laboratories Belo Horizonte (Vespasiano), Brazil , will be used as an alternate or umpire laboratory, with base metal analysis by four acid digest and ICPOES finish (ICP40B/ ICP40BS), and gold by fire assay with AAS finish (FAA505 / FAA525).

A representative selection of coarse rejects from the sampling program will be sent for QEMSCAN analysis (Quantitative Evaluation of Minerals by Scanning Electron Microscopy) as part of a first phase of metallurgical studies. With a view to validate Cabaal's historical metallurgical performance of producing, via high recoveries, Copper-Gold plus Silver concentrates with negligible impurities.
Geophysical surveys are being conducted by GeoMag, using a TEM57-MK2 Transmitter and PROTEM receiver for surface surveys and BH43-3 borehole three-dimensional time domain (TDEM) probe for sub-surface work. Quality control is performed daily by the geophysical representative of the Wellfield Group, before and data sent to the Company's independent consultant, Core Geophysics. Modelling of conductivity responses is undertaken using industry-standard Maxwell software.

Dr Adrian McArthur , CEO, states, "the Company has successfully started its drill program and surface EM surveys at Cabaal. We have been able to manage this in a short time since acquiring Cabaal and it shows the depth of experience of our Brazilian management team's field experience and also the positive pro-work and pro-investment focus of the Brazilian regulatory authorities. This program is being conducted under the strictest of preventative health and safety systems put in place and expanded during the Covid pandemic. The rigs are both drilling down towards Cabaal's mineralised geological horizons."
