Abenab Vanadium Project

PROJECT OVERVIEW

The Grootfontein Base Metal Project of the Abenab Vandium Project forms part, is located on licences in the Otavi Mountain Land (OML) of Northern Namibia, an area roughly bounded by a triangle linking the towns of Tsumeb, Grootfontein and Otavi. The region hosts several globally significant copper, zinc, lead, silver and vanadium mines, including the Tsumeb, Khusib Springs, Abenab, Berg Aukas & Kombat mines.

The region is well served by sealed roads, rail to port, high voltage power, telephone and water, and is close to major towns and mining processing facilities, including the Kombat copper concentrator and Tsumeb Smelter complex (one of only five operating smelters in Africa).

The Grootfontein Project has a number of significant prospects near historical production centres located on its licences. These prospects include the Askevold Copper trend, the Abenab Vandium-Lead-Zinc trend and the Khusib Springs Copper prospect.

Each base metal trend contains at least one high priority advanced project, such as a historically drilled mineral deposit or an abandoned mine with remnant resource potential. These advanced projects on the Abenab Trend will be the main focus of The Company’s immediate exploration efforts.

The Abenab Trend is marked by a series of V-Pb-Zn occurrences located near the contact between the Auros Shale and Maieberg Dolomites. The Abenab, Abenab West and Okurundu mines are located on this contact position and represent high priority vanadium targets. Approximately 40km strike extent of this highly prospective trend lies within The Company’s EPL3543.

 Abenab Vanadium

The mineralisation style at Abenab is rare with the main mineral being descloizite, a lead-zinc vanadate (PB,Zn)2(OH)VO4. The ore body is contained in a breccia pipe with the majority vanadium minerals contained within a red clay. The V-Pb-Zn minerals are descloisite (Pb,Zn(VO4)(OH)) and vanadinite (Pb5(VO4)3Cl) that are hosted within quartz-carbonate breccia, red clay breccia and also quartz veins.

The is situated on a long, narrow (730 m x 6 m) zone of deformation and associated bedding-parallel faulting. Solution cavities in the fault breccia are filled by unconsolidated, ferruginous “clay” containing descloizite and galena in the upper levels. A deposit of willemite [Zn2SiO4], found in outcrop at the eastern extremity of the mineralised zone, does not persist at depth. Cavities are in places filled by red layered clay containing vanadium minerals, and coarse gritty material consisting of quartz, cerussite, limonite and vanadates.

A JORC 2012 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, which equates to 18.5kt vanadium pentoxide, 65.8kt lead and 26.3kt zinc has been determined at Abenab.

Golden Deeps Limited holds over 40km of the Abenab mineralised trend that includes the Abenab West Mine, Okarundu Pipe Vanadium Mine and the Nosib Mine. In addition to the above, nine other vanadium occurrences have been identified along the trend as well as several base metal occurrences.

There has been very little if any modern exploration of the mines and targets. The Company has begun field reconnaissance and sampling of priority targets as part of it’s ongoing exploration strategy. Abenab West Mine, Nosib Mine and selected targets will be drill tested at the completion of the current drilling programme.

The Khusib Trend is an east west trending zone of copper anomalies and prospects associated with a contact zone between Maieberg dolomites and limestones. This is known as the T2/T3 contact position. The portion of the Khusib Trend located within The Company’s EPLs is bounded by the Pickaxe Prospect in the west and continues north east for over six kilometres, with the Khusib Springs copper mine located near the centre, 3km north east of Pickaxe. The Khusib Trend is located in a similar structural and stratigraphic position to the lead zinc Pavian Trend to the south.
 

The Askevold trend is defined by a series of copper occurrences and geochemical anomalies associated with a sheared contact between the Askevold Volcanics and the overlying Abenab Dolomites. Recent petrographic studies have shown that the mineralisation style is shear-hosted hydrothermal, more so than VMS, and have revealed a FeO-Cu-Au style mineral assemblage. The company has several EPL applications on and around this trend.
