KIHABE – NXUU ZINC/LEAD/SILVER PROJECT, WESTERN NGAMILAND, BOTSWANA
Following the grant of a new Prospecting Licence PL 43/2016 on 26 January 2016, over the Kihabe – Nxuu Project, the Company has been involved in designing a proposed route to advance the project from hereon.
INDEPENDENT GEOLOGICAL REVIEW
CSA Global has been selected to complete an independent geological review of the project’s Mineral Resources and exploration potential. CSA Global’s preliminary assessment concluded that “It is obviously a huge system in a known productive basin and a system where it should be possible to develop an effective targeting model”.
The project has a Mineral Resource Estimate reported under the 2004 JORC Code of 25.3 million tonnes at 3% Zn equivalent which includes 3.577 million ozs silver (refer to Resource Statement attached). There is potential to further expand the resource base.
METALLURGICAL REVIEW
Mr Chris Campbell-Hicks, metallurgist and Director of the Company has been investigating potential metallurgical processing routes for the recovery of zinc, lead and silver from both the oxide and sulphide zones of the Kihabe and Nxuu resources. This has also included investigating the potential for recovering known credits within the resource base, such as copper, vanadium, gallium, germanium and indium.
With the provision of grid power the potential exists for the production of zinc metal on site from the oxide zones of the resources through acid leaching, solvent extraction and electrowinning (SX/EW). This process could also allow for the recovery of gallium and germanium.
Since the mineralisation contains both oxide and sulphide minerals, together with an anticipated transition zone, an improved metallurgical design flowsheet will be required. A test work program has also been designed to determine the ability to produce separate zinc/silver and lead/silver flotation concentrates from the oxide zones using control potential sulphidisation. The greatly reduced mass of the separate zinc concentrate can then be acid leached with a significant downsizing of the zinc acid leach circuit with a consequent reduction in initial capital cost, reagent consumption and mill power required for the finer grind requirements of the
leach feed. The lead/silver concentrate remains available for sale as with all other process pathway options.
The significant increase in the silver values in the leached zinc concentrate residue also provides a possibility for extracting much of the remaining silver by gravity techniques lifting overall silver recoveries from a typical 60 – 65% to 80 – 90%.
INITIAL ACCESS TO HIGH GRADE ZONES OF NEAR SURFACE MINERALISATION
The Company is also investigating a potential mining schedule to allow for initial access to higher grade zones of the near surface oxide resources, maximising project capital repayment within the shortest possible time frame.
CONFIRMATION OF HIGHER RESOURCE GRADES FROM DIAMOND CORE DRILLING VERSUS RC DRILLING
From drilling conducted to date by the Company, through twinning RC holes with diamond core (DD) holes there appears to be a grade increase of around 48% between the DD results versus RC results. Additional DD will have to be conducted to verify this increment which has the potential to increase the Kihabe and Nxuu resources grades.
POTENTIAL TO INCREASE THE PROJECTS RESOURCE BASE
The Kihabe – Nxuu project has previously been interpreted as stratabound SEDEX (“sedimentary-exhalative”) style of mineralisation within this Neoproterozoic sedimentary basin, contiguous with the Damaran in Namibia where a number of significant Zn-Pb deposits are known. Mineralisation in both the Kihabe and Nxuu resources is stratabound at a stratigraphic contact between a quartz wacke unit and a dolostone unit. The Company believes that there is potential to discover further similar zinc/lead/silver mineral deposits through testing additional geochemical anomalies at the same dolostone/quartz wacke contact, which is typically buried beneath 5m to 15m of Kalahari sand cover.
From geochemical soil sampling conducted to date, the Company has generated, six new zinc/lead anomalies and one copper/cobalt anomaly now ready for drill testing. Three of the zinc/lead anomalies and the copper/cobalt anomaly are interpreted to lie over the dolostone/quartz wacke stratigraphic contact. This has been verified by regional drilling where one hole has intersected dolostone and an adjacent hole has intersected quartz wacke, with subsequent geochemical soil sampling conducted between the two holes delineating a geochemical anomaly. The Target 52 anomaly, coincident with a fold closure, is some 5.4 Km long, suggesting potential for a large zone of mineralisation.
POWER
As reported by Mmegi Botswana on 9 March 2016, the Ministry of Minerals Energy and Water Resources, Botswana, confirmed the appointment of Marubeni of Japan and Posco of South Korea to construct two additional coal-fired power units to add an extra 300MW of electricity production from the Morupule B coal-fired power project. With all six units functioning the Morupule B power project should produce
900 MW of power to be integrated into Botswana’s grid power system. Another 300 MW greenfield power plant is currently out for tender and the refurbishment of the original 120 MW Morupule A power plant is currently being conducted by Doosan Heavy Industries of South Korea.
With this increased power production it is expected that Botswana will become a net exporter of power within three years.
The Company has also been in discussions with ECG Engineering of Western Australia, which company has been involved in projects in Africa generating gas from coal for power generation.
There are further plans for the construction of a main power line from the Morupule area in eastern Botswana through to Shakawe in north western Botswana, enabling projects in Western Ngamiland to access grid power.
