Tsodilo Resources Engages SRK Consulting (U.K.) Limited to Prepare an Initial 43-101 Resource Estimate and Technical Report on its Xaudum Iron Ore Project
Toronto, Ontario CANADA, December 30, 2013 /FSC/ – Tsodilo Resources Limited (TSD – TSX Venture), (“Tsodilo” or the “Company”) is pleased to announce it has engaged SRK Consulting (U.K.) Limited (“SRK”) to prepare an initial National Instrument 43-101 compliant Mineral Resource Estimate and Technical Report for the Company’s Botswana subsidiary, Gcwihaba Resources (Pty) Limited (“Gcwihaba”), on a portion of the Xaudum Iron Ore Project.
Xaudum Iron Ore Project
The Xaudum Iron Formation (XIF) is located in the northern portion of the Ngamiland region in the North-West District of Botswana. The XIF generally does not outcrop and is considered a buried prospect. The XIF is buried below the “Kalahari cover” (made up of sand and calcrete) and has been delineated for exploration drilling using detailed ground magnetic surveys conducted by the Company over the area. The ground magnetic survey comprises 18,000 line kilometers (“km”) on lines 50 meters apart with readings taken approximately every 5 meters and covers 1,600 km2.
Drilling to date has confirmed that the XIF is comprised of two units:
1. Magnetite Banded Iron Formation (BIF) unit, which can be weathered near surface (just below the Kalahari cover).
2. Magnetite Schist unit, which can also be weathered near surface.
These units are significantly magnetic, although the Magnetite BIF is more magnetic and can be considered a high grade magnetite unit, whereas the Magnetite Schist represents a less magnetic but potentially more widespread lower grade target unit.
Both units are believed to represents metamorphosed chemical sediments that have been highly deformed, resulting in strong and well-developed banding in the Magnetic BIF and a strong foliation within the Magnetic Schist. The magnetite mineralization is more disseminated within the Magnetite Schist and not as obviously partitioned into bands like the Magnetite BIF.
It is unclear whether these Magnetite BIF and Magnetite Schist units are comprised of single or multiple stratigraphic units. The intense deformation, folding and potential thrusting that these units have undergone, means defining stratigraphy and true thicknesses is difficult to determine, especially at this relatively early stage of resource drilling.
Recent metallurgical Davis Tube Recovery (DTR) test work (See press release, December 17, 2013) confirmed the premium grade magnetite product potential of the Xaudum Iron Ore Project, where all mineralized units are capable of producing premium grade magnetite product of >68 % Fe and very low deleterious elements. The DTR test work confirmed that the coarse grained nature of the mineralization allowed for good concentrate grades at relatively coarse grind sizes. Good mass recoveries were achieved for all mineralized units given the amount of magnetic minerals in the starting material. Further to this, the test work also confirms that partially oxidized (weathered) material can still be separated with higher than expected mass recoveries.
The two mineralized XIF units occur as smaller sub-units within a greater diamictite schist formation of glacial origin and are part of the Neoproterozoic age rocks in the region. The mineralized Magnetite Schist unit itself is a magnetic (high in magnetite) version of this greater diamictite schist formation which in the main is non-magnetic, and therefore the mineralized Magnetic Schist unit is also referred to as a magnetite diamictite or magnetic diamictite.
The XIF has been identified as a Rapitan style BIF of Neoproterozoic age. Neoproterozoic BIF formations have been proposed to have formed during or in the immediate aftermath of the so-called Neoproterozoic “Snowball Earth” state at that time (considered to be around 0.6-0.8 Ga in age). Other examples of this Neoproterozoic BIF include the Rapitan Group in northwest Canada (18.6 billion tonnes at 47% Fe); the Yudnamutara Subgroup, Braemar Iron Formation, Australia (1.4 billion tonnes at 15.5% Fe), the Chuos Formation (Namibia) and the Jacadigo Group (Brazil, Urucum district) ~30+ Billion tonnes at ~50% Fe).
RESOURCE ESTIMATE REPORT SCOPE OF WORK
The scope of work of the mineral resource report to be undertaken with SRK is detailed below. Mineral resource reporting will be consistent with CIM standards and will include but is not restricted to the following:
. Qualified person site visit to ALS Laboratory in Johannesburg and observe the geology and exploration protocols employed by Gcwihaba in Ngamiland;
. Quantity and quality review of all data collected by Gcwihaba to be used in the estimation process;
. Desktop structural study of the asset to support the geological interpretation and modelling being undertaken by Gcwihaba;
. Review of the geological interpretation and wireframes, providing feedback to Gcwihaba to allow amendments to the interpretation to be implemented;
. Statistical study on the sample data that have been coded using the wireframe geological / mineralization model and for all relevant elements and density measurements;
. Geostatistical Study on the same domains as for the statistical study, in order to determine a suitable block size and suitable estimation parameters for grade interpolation;
. Interpolation of the sample grades into the 3D block model using appropriate estimation parameters and based upon the results of the statistical and geostatistical studies;
. Validation of the interpolated sample grades in the block model through visual and statistical assessments;
. Mineral Resource classification in accordance with the CIM Code;
. A review of all metallurgical data collected on the asset to assist in defining appropriate metallurgical recovery parameters to be included in the pit optimization studies;
. Pit optimization studies in order to define the cut-off-grade and economically mineable portions of the Mineral Resources using parameters suitably optimistic that have been benchmarked against similar operations; and
. Preparation of a CIM compliant Mineral Resource statement and accompanying grade-tonnage curves and sensitivity analysis.
“Tsodilo is pleased to be working with SRK on its Xaudum Iron Ore Project” stated James M. Bruchs, Chairman and CEO, “SRK’s global experience and in-house expertise in similar magnetite Iron Ore projects to the Xaudum Iron Formation are second to none, and will provide the range of services we require to advance this project in a timely manner.”
