- Resource drilling has defined broad packages of mineralisation at Tenge. Analytical results from the first 3 drill holes have been returned with a further 23 drill holes currently undergoing analysis.
- Significant drill intercepts include 115m at a head grade of 36% Fe and a DTR concentrate grade of 63% Fe, 0.9% V2O5 and 6.6% TiO2 at a mass recovery of 37% from 19.5m in TGDH0002A.
- Coffey Mining is on schedule to complete the Tenge resource estimate by March 2012 which has the potential to add substantially to the current 324Mt global inventory.
- Pre-Feasibility Study (PFS) management team finalised; contracts signed with international consulting groups Coffey Mining and SNC-Lavalin as well as respected industry specialist Dr. John Clout.
Commenting today, Ben James, Baobab's Managing Director, said: "The first round of drill results from Tenge are encouraging and show a strong correlation with the grade characteristics of the Ruoni North and Ruoni South resource blocks. The Tenge resource, due out in March, is expected to push the global resource base well beyond Baobab's targeted 300Mt which will allow scope for ramping up production.
"The Company has also drawn together an excellent team of industry specialists to complete the PFS in good order and looks forward to regularly updating investors on progress."
TENGE RESOURCE DRILLING
Tenge/Ruoni is the easternmost prospect area of the Massamba Group. Drilling at Tenge/Ruoni has intersected a heavily mineralised package varying in thickness from 60m to 150m. Mineralisation has been synformally folded with the fold hinge plunging gently to the west-northwest. Exploration campaigns in the prospect area have been divided into three resource blocks:
- - Ruoni North: representing 1km of strike along the northern limb of the fold. Thirty seven reverse circulation (RC) and diamond holes have been completed to date across seven traverses for an aggregate total of c.5,750m. Drilling has intersected a substantial package of mineralisation from surface dipping at 25° to 50° to the southwest.
On 31 October 2011, the Company announced the estimation of a 93Mt Inferred Resource at Ruoni North. Further drilling has subsequently been completed and the Company is confident that portions of the Inferred Resource will be elevated to Indicated once the analytical results have been returned.
- - Ruoni South: representing 1.2km of strike along the southern limb of the fold. Twenty seven RC and diamond holes have been completed for an aggregate total of 5,200m. Mineralisation in the Ruoni South area is generally steeper dipping (c.65° to the north).
On 7 December, the Company announced the estimation of a 56Mt Inferred Resource at Ruoni South. Of particular interest is the 0.9% V2O5 concentrate grade which is 12% higher than results reported from Ruoni North and some 28% higher than indicated concentrate grades from South Zone and Chitongue Grande resource areas.
- - Tenge: representing the hinge zone of the fold and covering a strike length of approximately 1.3km. A 4,800m programme of diamond and RC drilling (26 drill holes) has been completed.
Consultant, Coffey Mining Pty Ltd ('Coffey'), is currently developing a geological model for the Tenge block and expects to finalise a resource estimate during March 2012. All resource statements are completed in accordance with the Joint Ore Reserves Committee (JORC) guidelines.
Analytical results for diamond holes TGDH0002, 2A and 6 have been returned. Sample preparation at 0.5m to 1m composite intervals was completed by ACT-UIS laboratories in Tete, Mozambique, prior to despatch to ALS Chemex laboratories in Perth, Western Australia, for further compositing (maximum composite length of 6m), Davis Tube Recovery (DTR) and X-ray Fluorescence Spectrometry (XRF) analysis. Samples from all remaining Tenge diamond and RC drill holes are currently undergoing analysis at the Perth laboratory.
TETE PROJECT OVERVIEW
The project is located in the richly endowed Tete province of Mozambique. The province hosts some of the largest undeveloped coal reserves on the planet and, with estimates pointing towards the area producing up to 20% of the world's coking coal by 2015, is fast-tracking to become a mining and industrial hub of global significance.
Immediately south of Baobab's tenure, and sharing the Company's licence boundaries, are c.15Bt of coking and thermal coal resources being brought into production by two of the world's largest mining houses, Rio Tinto and Vale, along with premier steel producers, Tata Steel, Nippon Steel, Jindal Steel and Posco. Other operators in the area include AIM listed companies Beacon Hill Resources plc, Ncondezi Coal Company plc and Eurasian Natural Resources Corporation plc (ENRC).
Low tariff hydro-electric power is readily available from the 2,075 megawatt Cahora Bassa dam. Studies are underway to expand the dam's capacity by an additional 1,300 megawatts. A new 1,500 megawatt scheme at Mphanda N'kuwa, also on the Zambezi, is in advanced planning stages and due to commence production in 2015. The Company believes that it will be able to negotiate tariff rates at a third, if not a quarter, of typical power generation costs in Australia or west Africa which will have a significant impact on future operating costs.
The railway connecting Tete with the port of Beira is being refurbished, as is the port. The deep water port of Nacala and railway linking the port with the interior is also being refurbished under the auspices of a consortium including the Mozambique government, Vale and the World Bank. An order of magnitude study has been completed on a dedicated heavy haulage railway to a Greenfields port located within 500km of Tete.
The Project straddles the central portion of the Tete Mafic Complex and contains two areas of titano-magnetite / ilmenite mineralisation; the Singore area to the south and the Massamba Group in the north. The Massamba Group is composed of a series of three prospects (Chitongue Grande, Chimbala and South Zone) forming an 8km long trend and the 3.5km long Tenge / Ruoni prospect to the east.
Building on the successful exploration programmes of 2009 and 2010, Baobab accelerated activities in 2011 to achieve two key milestones; to define a minimum resource base of 300Mt on which a Scoping Study could be finalised. The Company completed an aggressive c.40,000m drilling campaign that resulted in the expansion of the global resource base to an interim 324Mt (please refer to RNS dated 7 December 2011 for details). An additional resource statement at Tenge, due for release during March 2012, is set to enlarge the inventory again, pushing it towards 500Mt.
The Scoping Study, completed by independent consultants and applying conventional beneficiation and smelting technologies, assessed two production scenarios:
- Scenario 'A': base-case production of 3Mtpa titano-magnetite concentrate and 0.5Mtpa ilmenite concentrate products for export. Initial capital expenditure (capex) estimate of US$448m.
- Scenario 'B': capitalising on the Project's access to low tariff hydro-electric power and strategic proximity to thermal coal reserves to add further value on site through the mine-mouth smelting of 1Mtpa pig iron. Initial capex estimate of US$690m.
While the base-case model for scenario 'A' demonstrated viable Project fundamentals, the optimisations and financial modelling of Scenario 'B' at a 10% discount rate provided compelling economics with pre-tax net present value (NPV10) and internal rate of return (IRR) figures of US$1.4b and 34% respectively. The estimated average annual net cash flow after capex over the modelled 25 year mine life is US$275m.
The Scoping Study results show very clearly the 'value add' from the plans for on-site smelting of pig iron and underlines the strategic advantages of the Project's unique geography with respect to infrastructure and complementary resources. Producing a higher value, high demand product will not only broaden the market base, but also mitigate the requirement to compete for rail and port access.
The vanadium potential remains to be modelled and could add further to the value of this project. Reduced input costs through long-term domestic coal contracts and on-site power co-generation also need to be assessed, while the expanding resource base at Tenge/Ruoni, underpinning a meaningful +30 year mine life, allows scope for ramping up production.
For a detailed summary of the Scoping Study, please refer to RNS dated 29 November 2011.
