B2Gold Corp. (TSX:BTO)(NYSE MKT:BTG)(NAMIBIAN:B2G) announce further positive drilling results from the exploration program at the Otjikoto gold project in Namibia.
These positive drill results, as detailed below, indicate the potential to outline additional higher grade resources that could lead to the expansion of production and an increased mine life at the Otjikoto gold project. The project, currently in construction, is on schedule and on budget to commence production in the fourth quarter of 2014.
Exploration Drill Results
An additional 60 diamond drill holes have been drilled on the Otjikoto project since the last update (see news release dated April 10, 2013) bringing the year to date drill holes completed to 107 for a total of 22,194 metres. The majority of the new holes were drilled on the Wolfshag zone discovery, situated immediately to the east and northeast of the planned open pit on the main Otjikoto deposit. Recent drilling on the Wolfshag zone has concentrated on infill drilling of the northern portion of the zone, from 7800N to 8800N, with 100 metres spaced sections and 25 metres hole spacing on section.
Significant new results from the Wolfshag drilling include, from north to south:
- WH13-073 with 18.85 metres at 5.84 grams per tonne (g/t) gold, including 13.75 metres at 7.00 g/t gold;
- WH13-083 with 24.60 metres at 5.35 g/t gold, including 8.80 metres at 11.26 g/t gold;
- WH13-095 with 13.55 metres at 6.83 g/t gold, including 5.30 metres at 16.74 g/t gold;
- WH13-078 with 18.65 metres at 7.11 g/t gold, including 5.60 metres at 15.51 g/t gold;
- OT13-355 with 13.65 metres at 6.13 g/t gold, including 4.85 metres at 13.61 g/t gold; and 6.35 metres at 7.10 g/t gold;
- OT13-362 with 15.00 metres at 6.64 g/t gold, including 3.90 metres at 10.83 g/t gold;
- OT13-361 with 23.80 metres at 3.15 g/t gold and 20.75 metres at 3.18 g/t gold, including 6.20 metres at 9.00 g/t gold, and 9.00 metres at 2.66 g/t gold, including 3.00 metres at 6.83 g/t gold;
- OT13-365 with 11.40 metres at 3.92 g/t gold, including 5.10 metres at 7.34 g/t gold;
- OT13-366B with 5.40 metres at 5.60 g/t gold and 11.00 metres at 6.04 g/t gold, including 4.20 metres at 12.19 g/t gold.
(A table of selected results is at the end of this release)
The current phase of infill drilling will upgrade the Wolfshag zone to an inferred resource and will be completed in the next two weeks. The initial inferred resource estimate for the zone is expected by year end. The Otjikoto exploration budget for 2013 is $8.0 million. More drill results will be released as they are available. The Wolfshag zone has been defined over 1,600 metres and the mineralized system remains open down plunge to the south and extends up to the base of the calcrete, at about 10 to 15 metres below surface, to the north.
It is important to note that the average mineable grade of the adjacent main Otjikoto deposit is 1.42 g/t gold as stated in the feasibility study. Based on the proximity of the Wolfshag zone to the planned Otjikoto open pit, the Company believes a significant amount of the Wolfshag mineralization could be included in an expanded pit, subject to further drilling and final mine plan. The Company intends to update the mine plan to incorporate the Wolfshag zone once infill drilling has upgraded the resource to indicated next year.
The Otjikoto gold project is located approximately 300 kilometres north of Windhoek, the capital of Namibia, and is owned 90% by B2Gold and 10% by EVI Gold (Pty) Ltd ("EVI Gold"), a Namibian empowerment group. The Otjikoto deposit has probable open pit mineral reserves of 29.4 million tonnes at a grade of 1.42 g/t gold containing 1.34 million ounces of gold (based on the Company's feasibility study released January 10, 2013).
The life of the open pit mine, based on the probable reserves, is estimated to be 12 years, with annual forecast gold production of approximately 141,000 ounces gold per year for the first five years at an average operating cash cost of $524 per ounce of gold and for the life of mine approximately 112,000 ounces of gold per year at an average operating cash cost of $689 per ounce.
Construction of the Otjikoto Gold Mine is ongoing, on schedule and on budget. Construction commenced January 2013 and will continue into the fourth quarter of 2014. It is anticipated that gold will be produced during the fourth quarter of 2014 with a ramp up to full production in early 2015.
The necessary bush clearing has been completed and all necessary internal roads have been roughed in. All mining equipment for the initial stages of mine development has arrived at site and mining has commenced. Development of Pushback 1 has been on-going since the beginning of June and the equipment workshop is almost complete. Work at the mill is focusing on development of the necessary infrastructure needed to complete the mill erection and stockpiling of the necessary sand and aggregate for concrete and engineered fill material. This includes erection of the construction shop and office complex. More than 95% of the topsoil has been removed from the tailings basin and liner installation will commence in the third quarter of 2013. The mancamp (capable of housing up to 600 persons) is nearing completion and is expected to be commissioned in July, 2013. Currently, B2Gold Namibia employs more than 150 persons and expects to increase to more than 600 persons in the third quarter (based on the Company's feasibility study released January 10, 2013).
Update on the Otjikoto Joint Venture Structure
The Company has completed a transaction with its partner EVI Gold on the Otjikoto project in Namibia in which, among other things, EVI Gold exercised its right to increase its ownership interest in the Otjikoto project from 8% to 10% for consideration of US$5 million. In addition, as partial consideration for the issuance to EVI Gold of common shares of the Company, EVI Gold has transferred its rights to acquire an additional 5% interest in the Otjikoto project to the Company. Accordingly, the Company and EVI Gold now hold a 90% and 10% interest, respectively, in the Otjikoto project.
Wolfshag Zone Geology
The Wolfshag zone consists of a series of en-echelon stacked, shallow easterly dipping and south-southeast plunging mineralized shoots hosted within albitite + calcite + clay altered metasediments and marble lenses. The Wolfshag mineralized zone is bounded by folded, recrystallized and sheared marbles, the West and East marbles, within a thrust ramp complex. Mineralization consists of pyrite-magnetite-calcite in veins, steep tension gashes and replacement zones. Visible gold is common in the southern portion of the Wolfshag zone, but less abundant than in the Otjikoto deposit mineralization. The main, upper, WA shoot at Wolfshag ranges in thickness from 5 to 35 metres and width from 50 to 100 metres. The lower zones are not as well defined as the WA shoot. Wolfshag mineralization is situated below the OTB and footwall marble marker horizons and the main Otjikoto deposit ore shoots.
Results to date for the Wolfshag zone confirm the continuity of the various stacked mineralized shoots within the zone with the most consistent high gold grades occurring within the central portion of the WA shoot. Furthermore, infill drilling confirms the continuation of higher gold grades originally intersected at deeper levels of the zone, e.g. OTG10D with 20.0 metres at 7.55 g/t gold (see news release dated December 11, 2012), to shallower depths. For example hole WH13-073 intersected 18.85 metres at 5.84 g/t gold starting at 74.0 metres downhole and hole WH13-083 intersected 24.60 metres at 5.35 g/t gold, including 8.80 metres at 11.26 g/t gold, starting at 106.90 metres downhole. Hole OT13-366B, drilled on section 7200N between deepened holes OT219D and OT228D (see news release date April 10, 2013), also confirms the extension of higher grade shoots to depth with 11.00 metres at 6.04 g/t gold intersected starting at 489 metres downhole.
A summary of selected recent Wolfshag zone results is tabulated below:
*The geometry of the lower, eastern shoots is not fully understood at this time. True widths are believed to be 85-90% of intersected widths.
