Confirms Continuous High-Grade Copper Mineralisation And Expansion Of Camp Scale Potential
Meridian Mining UK S (TSXV: MNO) has received promising additional results from its surface and borehole Electromagnetic (E”) surveys at its Cabaçal Copper-Gold VMS project in Mato Grosso. Brazil.
To date, strong Copper (Cu) dominant sulphides assemblages hosting Gold (Au) and Silver (Ag) mineralisation have been intercepted by the ongoing 10,000m Cabaçal drill programme adjacent and within to the historical mine’s underground workings.
Bore Hole EM surveys (BHEM) have now mapped multiple EM plates, confirming that extensive conductive layers of Cu sulphide (+Au-Ag) remain within and extend out from the old workings.
Additionally, the 2007 EM survey (VTEM) at Cabaçal has been reinterpreted using its now recently defined “Cabaçal” type EM response with promising results.
This has mapped north and south EM extensions out from the mine area, a 700m anomaly adjacent to the St Helena mine and a major new four km long EM anomaly 1.7km south-east of the St Helena mine and along strike from an open south-east trending polymetallic soil anomaly.
CEO, Dr Adrian McArthur, said these results validate Meridian’s belief that Cabaçal could host multiple deposits typical of a camp-scale VMS project.
“The growing dataset of bore hole conductivity measurements coupled with our ongoing drilling has validated the anecdotal reports that significant copper and lower grade gold mineralisation was not mined due to the high ‘gold’ only cut-off grade of 3g/t historically used,” Dr McArthur said.
“Our drilling of concentrated stringer and breccia mineralisation flanking historical mining voids shows the significant resource upside over both the footprint of the existing workings and the unmined extensions.
“The re-interpretation of the regional VTEM survey greatly supports the near mine and camp scale potential of the Cabaçal project. The EM trend heading out from the mine towards the down plunge bedrock late channel conductor of Cabaçal West is an exciting development for the project. Regional results including defining a new 4.0 km long Cabaçal type EM discovery south of the mine highlight the potential for future discoveries using EM surveys, the most common tool for discovering VMS deposits.
“With our own modern and more powerful surface and downhole EM equipment expected onsite in June we can hopefully report future exciting geophysical results to our shareholders in the months ahead. Our next batch of assays from the Cabaçal’s drill programme will be released shortly and will be reporting holes CD005 to CD009.”
