| ABSTRACT: | GALENA MINING LTD. ("Galena" or the “Company”) (ASX: G1A) announces completion of an updated JORC Code compliant Mineral Resource estimate (“December 2018 Resource”) for its wholly-owned Abra Base Metals Project (“Abra” or the “Project”) located in the Gascoyne region of Western Australia, which has been independently prepared by Optiro Pty Ltd (“Optiro”). In addition, Galena has prepared an updated JORC Code compliant Ore Reserve estimate (“December 2018 Reserve”) and a revised mining inventory assessed on the new Resource. Managing Director, Alex Molyneux commented, “It’s really pleasing to continue Abra’s development with updated resources, reserves and the new mining inventory model. We’re very excited about the extra grade and metal over the reduced lateral development and their combined potential for material enhancement to the economics of Abra.” Abra lies within sediments of the Proterozoic Edmund Group. Abra is a base metal replacementstyle deposit hosted by sediments. The primary economic metal is lead. Silver, copper, zinc and gold are also present but are of lower tenor. The deposit can be divided into two main parts. The upper “Apron Zone” comprises stratiform massive and disseminated lead sulphides (galena) and minor copper sulphides (chalcopyrite) within a highly altered sequence of clastic and dolomitic sediments. Alteration products include jaspilitic rich sediments (the “Red Zone”) and a distinctive stratiform zone of hematite-magnetite alteration (the “Black Zone”). The Apron Zone extends for 1,000 metres along strike, 800 metres down dip and dips gently south. The “Core Zone” underlies the Apron Zone and comprises an elongate funnel shaped body of hydrothermal breccias, veining and intense alteration overprinting gently south dipping sediments. The veining and breccia zones in the Core Zone form a feeder style flower shaped geometry in cross section. Hydrothermal veining dips moderately south on the northern flank, sub-vertically in the central parts and gently to the north on the southern margins. High-grade lead sulphide mineralisation is predominantly hosted in intensely veined zones. High-grade zinc sulphide mineralisation (sphalerite) is found in the central parts of the Core Zone. Copper (chalcopyrite) and gold mineralisation is sporadically found throughout the upper parts of the Core Zone but forms a semi-coherent body at the base of Core Zone. The Core Zone extends from 300 metres to 750 metres below surface and can be traced for 400 metres along strike | |
