Significant Intervals In Resource Definition Programme In Brazil
Meridian Mining UK S (TSXV:MNO) has received another positive batch of assays from its ongoing 10,000m resource delineation programme at its Cabaçal Copper-Gold camp scale VMS project in Mato Grosso, Brazil.
CEO and President, Dr Adrian McArthur, said Holes CD-005 through to CD-009 have returned significant intervals and grades of Copper, Gold and Silver mineralisation across and outside of the limits of the historical Cabaçal Mine.
The Cabaçal mine was previously operated by BP Minerals/ Rio Tinto, using a high Au only 3.0g/t cut-off grade. The recurring presence of high-grade Au intercepts within the broad Cu-Au zones, confirm that the Cabaçal mine’s high-grade Au veins were mined to the limits of the resource data and not to the limit of the Cu-Au mineralisation – which remains open.
Drilling highlights include:
- CD-005 returned 30.7m @ 1.3% CuEq1 from 38.5m (0.9% Cu, 0.6/t Au, 4.9g/t Ag & 0.1% Zn);
- CD-006 returned 17.7m @ 2.4% CuEq from 113.0m (1.3% Cu, 1.5/t Au, 6.1g/t Ag & 0.3% Zn) Including a higher grade zone of: 11.5m @ 3.4% CuEq from 118.5m (1.9% Cu, 2.2g/t Au, 8.9g/t Ag & 0.3% Zn);
- CD-007 returned 35.1m @ 0.6% CuEq from 30.3m (0.5% Cu, 0.2g/t Au & 2.2g/t Ag); Including a higher-grade zone of: 9.5m @ 1.6% CuEq from 55.8m (1.3% Cu, 0.4g/t Au, 6.8g/t Ag, & 0.1% Zn);
- CD-008 returned 35.0m @ 0.5% CuEq from 30.0m (0.3% Cu, 0.2g/t Au, 1.0g/t Ag, & 0.2% Zn); Including a higher grade zone of: 12.2m @ 1.2% CuEq from 44.8m (0.8% Cu, 0.4g/t Au, 2.5g/t Ag & 0.4% Zn)
- CD-009 returned 66.1m @ 1.1% CuEq from 86.9m (0.6% Cu, 0.8g/t Au, 1.8g/t Ag); Including higher grade zones of: 2.7m @ 10.0% CuEq from 86.9m (1.5% Cu, 14.0g/t Au, 7.0g/t Ag & 0.1% Zn); and 12.8m @ 2.1% CuEq from 139.7m (1.7% Cu, 0.5g/t Au, 5.2g/t Ag & 0.1% Zn).
“Today’s drill results continue to deliver strong intervals of Copper and Gold, starting at shallow depths, from our Cabaçal project. Cabaçal’s drill results to date, featuring robust grades, wide intervals and excellent geometry combined with the known metallurgy of the Cabaçal mine, highlights the company’s potential to emerge as the next mid-tier copper-gold resource developer,” Dr McArthur said.
“Cabaçal was previously selectively mined within a series of gently dipping Copper-Gold sulphide layers using a high Gold-only cut-off grade of 3.0g/t within a much broader mineralised envelope.
“The current drilling has continued to intersect not only extensive copper mineralisation but also high-grade Gold (2.7m @ 14g/t Au), showing that high-grade trends remain open extending out from the limits of historical development. Also, it was noteworthy that the last 12.8m of CD-009 graded over 2.0% CuEq before being terminated by a mining void.
“As we continue to focus the first 8,000m of our inaugural 10,000m drill and trenching programme on the Cabaçal mine, we still have 2,000m budgeted to confirm the already defined near-mine and regional targets of our VMS camp. We expect that additional results will continue through the summer and autumn.”
Meridian’s drill results, mapping and Bore Hole Electro-Magnetic (“BHEM”) surveys completed to date have confirmed that significant thicknesses of Cu-Au mineralisation extend approximately 400m North-East South-West while the historical selective underground workings have a ~650m North-West South-East extent; the mineralisation is considered open. Cumulative Cu sulphide layers (+Au-Ag) intercepted have also exceed 60m in thickness.
