Galena Mining Ltd. publicizes the excellent end result from drill-hole AB195, drilled as a part of the not too long ago accomplished 2020 Abra Drilling Program and because the first ever gap drilled particularly targetting the interpreted copper- gold zone on the Abra Base Metals Mission.
HIGHLIGHTS:
- Excellent success from the primary ever gap at Abra drilled particularly to focus on the interpreted copper-gold zone (AB195) adjoining to and beneath present lead-silver mineralisation
- Vital copper-gold intersections from AB195 embrace:
• 3.0m at 4.2g/t gold and 1.1% copper from 670.7m,
• 2.0m at 6.9% copper from 698.1m, and
• 26.9m at 1.4% copper from 763.8m, together with:
▪ 8.9m at 2.3% copper from 773.0m - Vital copper and gold mineralisation in AB195 occurred throughout the potential copper-gold channel zone interpreted by the Firm’s geological and geophysical overview in 2020
- Downhole electromagnetic survey is deliberate to be carried out on AB195 throughout the second quarter of 2021 for the definition of conductive plates inside its neighborhood
Galena Mining Ltd. (“Galena” or the “Firm”) (ASX: G1A) publicizes the excellent end result from drill-hole AB195, drilled as a part of the not too long ago accomplished 2020 Abra Drilling Program and because the first ever gap drilled particularly targetting the interpreted copper- gold zone on the Abra Base Metals Mission (“Abra” or the “Mission”).
Managing Director, Alex Molyneux commented, “We’re astounded on the success of drill- gap AB195 in intersecting vital mineralisation the place we interpreted the gold and copper zone to be! We’re planning a follow-up downhole electromagnetic survey to happen in Q2 this 12 months to think about additional copper-gold focused drilling thereafter.”
DRILL-HOLE AB195 AND THE 2020 ABRA DRILLING PROGRAM
Drill-hole AB195, was drilled as a part of the 2020 Abra Drilling Program, which concluded in late-December with 57 diamond core drill-holes being efficiently accomplished for twenty-four,832 cumulative linear metres. It’s the primary ever drill-hole at Abra drilled to particularly goal the interpreted zone of gold and copper mineralisation mendacity instantly adjoining to and beneath the closely explored lead and silver mineralised zones.
AB195 was an excellent success, intersecting 3.0 metres at 4.2g/t gold and 1.1% copper from 670.7 metres, 2.0 metres at 6.9% copper from 698.1 metres, and 26.9 metres at 1.4% copper from 763.8 metres, together with 8.9 metres at 2.3% copper from 773.0m .
Previous to intersecting the copper-gold zone, drill-hole AB195 handed by way of the Abra lead- silver zones, with the next vital intersections:
- 8.0 metres at 8.0% lead and 17g/t silver from 406.8 metres
- 5.5 metres at 12.1% lead and 12g/t silver from 541.3 metres
- 11.3 metres at 6.6% lead and 10g/t silver from 559.8 metres
The success of AB195 is borne out by the very fact the numerous copper and gold mineralisation was intersected the place potential for gold-copper channels had been interpreted to be, primarily based on a significant geological and geophysical interpretation train carried out by the Firm in 2020 (see Galena ASX announcement of 26 June 2020) and Determine 1 (beneath). Moreover, grade and thickness parameters from sub-sections throughout the broarder intersection (ie, 8.9 metres at 2.3% copper) line up favourably in worth phrases with the lead-silver reserve grades.

The broader vital copper intersection in drill-hole AB195 occurred inside a forty five metre zone of visible intermittent large and disseminated copper-bearing chalcopyrite mineralisation from a down-hole depth of 752 metres (see pattern drill-core pictures in Determine 2 beneath).

Given time constraints and the opposite aims of the 2020 Abra Drilling Program, AB195 was the one gap drilled particularly to focus on the interpreted copper-gold zone. Nonetheless, its success bodes nicely for added follow-up work.
COPPER AND GOLD AT ABRA
The Abra deposit mineralisation system is characterised by a stratiform high-grade lead-silver mineralisation zone forming a number of layers of mineralisation over the complete deposit following preferable sedimentary horizons. This stratiform mineralisation overlays a funnel-shaped chlorite breccia with sub-vertical vein-stringer zones (“feeding constructions”) fashioned by quartz- barite-dolomite-galena bearing veins carrying high-grade mineralisation of galena and different sulphide minerals. This vein-stringer zone progressively adjustments with depth from lead-silver wealthy to copper-gold wealthy. The copper-gold mineralisation happens extra ceaselessly at sure depths within the Abra deposit as a result of steel zoning with lead-silver deposited on the high and copper-gold idenfitied additional down within the mineralisation system.
