Mining study shows potential of Abenab V-Pb-Zn project in Namibia
(Kitco News) - Golden Deeps today announced the completion of a positive mining study on the Abenab high-grade vanadium-lead-zinc project in the Otavi Mountain Land of Namibia.
The company said that the mining study has established that there is potential for a viable underground mining operation focused on the higher-grade portions of the current mineral resource at a targeted production rate of 14,500 tonnes per month (tpm) or 174,000 tonnes per annum (tpa) of high-grade vanadium ore.
Mining costs based on mechanised cut and fill methodology are estimated to be in the order of US$44/t at the above production rate and, with high-level processing cost assumptions, leads to an effective run of mine (ROM) break-even cut-off grade of 1% V2O5 equivalent (approximately 0.7% V2O5).
The mineral resource available to mine at the above ROM cut-off grade is 873,000 tonnes at an average grade of 1.6% EqV (approximately 1% V2O5). Mining recovery assuming planned ore-loss in the production cycle is in the order of 724,000 tonnes at 1.5% EqV (approximately 1% V2O5).
Meanwhile, the company said that a Phase 2 processing study is now underway examining potential for production of vanadium pentoxide (V2O5) as well as lead, zinc and potentially copper.
Additionally, the company noted that further exploration success, delineating additional resources, would increase the mineable resource inventory and extend mine-life as well as provide an opportunity for increased mining.
The Abenab V-Pb-Zn project covers a 35km strike-length of the prospective Abenab mineralised trend. The region is a globally significant base metal province with major historical production from several mines including the now closed Tsumeb, Kombat and Berg Aukas deposits.
The Abenab project contains an Inferred Mineral Resource of 2.80Mt @ 0.66% V2O5 (vanadium pentoxide), 2.35% Pb (lead), 0.94% Zn (zinc) at a 0.2% V2O5 cut-off. The project comprises three key areas – the surface mineralisation and tailings (from previous production), the existing previously producing open cut mine and potential underground workings.
