TORONTO, ONTARIO - Tsodilo Resources Limited ("Tsodilo" or the "Company") (TSX-V: TSD) (OTCQB: TSDRF) (FSE: TZO) is pleased to provide an update on its wholly owned Xaudum Iron Project. The Company has initiated geochemical analysis for grade determination and geotechnical test-work for Rock Mass Rating ("RMR") evaluation for the Preliminary Economic Assessment ("PEA") of its Xaudum Iron Formation ("XIF") project.

The following analysis and test works will be conducted:

• 755 samples from 10 drill holes within the XIF Block 2 area have been sent to ALS Chemex for analysis by:
• Element analysis by X-ray fluorescence ("XRF") using borate fusion beads; and
• LOI by muffle furnace (Table 1);
• 34 samples from 7 drill holes representing the main XIF geological domains (Table 2) have been sent for geotechnical laboratory test-work assessment to the Department of Mining and Geological Engineering at the Botswana International University of Science and Technology (BIUST), where:
• 18 samples will undergo Unconfined Compressive Strength ("UCS") testing;
• 8 samples will undergo Brazilian Tensile Strength (Brazilian Test) testing; and�
• 8 samples will undergo Direct Shear Strength tests on a selection of common discontinuities.

Overview
Metallurgical results show that the XIF magnetite product is expected to be a premium product containing 67% Fe which is preferable over lower grade iron ores (See, Press Release of 12/17/2013 on the Company's website). These high-grade ores and products currently command larger price premiums over standard ores (62% Fe) resulting in higher margins for suppliers of high-grade products.� Further to this, "cleaner" iron ores with a Fe content equal to or greater than 65% use less coal per unit of steel and as such produce lower emissions. The current global drive for lower emission steel production results in steel producers dramatically increasing their demand for these high-grade green ores. As this shift towards green steel and emission reduction continues the high grade XIF is uniquely placed to meet this emerging market.

Preliminary work on the Xaudum Iron project has defined a CIM compliant Inferred Mineral Resource Estimate of 441 million tonnes (Mt) with an average grade of 29.4% Fe, 41.0% SiO2, 6.1% Al2O3 and 0.3% P for the Block 1 magnetite XIF. Block 1 is a fraction of the potential XIF magnetite resource. An extrapolated exploration target has defined the XIF to be in the order of 5 to 7 billion tonnes at 15-40% Fe. This exploration target was generated by inversion modelling of ground magnetic geophysical data which was compared and moderated to volumes from drilling data within Block 1 and its potential quantity and grade is conceptual in nature. To date, there has been insufficient exploration to define a mineral resource other than in Block 1 and it is uncertain if further exploration will result in the target being delineated as a mineral resource.

Tsodilo's Chairman and CEO, James M. Bruchs, commented "These results will be important to the technical evaluation and economic understanding of the project and will be included in the PEA. The iron ore market is entering a new "Super Cycle" based on improving fundamentals and a healthy market and has recently recorded the highest price on record. This encouraging market outlook coupled with the gathering pace of the green steel revolution means that we are confident that the PEA will bring strong added value to the Company as we develop this project towards mining."

Iron Analysis
755 samples have been consigned for XRF chemical assay to the ALS Chemex Minerals Division Geochemistry laboratory (ALS) in Johannesburg, South Africa for Fe analysis by industry standard XRF borate fusion beads and LOI by muffle furnace. These samples represent 1,230 meters of high grade XIF mineralization within the Block 2a area, see Table 1 for the details of these samples sent for assay.

Geotechnical Test-Works
34 samples from the main XIF geological domains that will comprise the majority of the envisioned pit walls have been sent for geotechnical test-work to the Department of Mining and Geological Engineering at BIUST.
Laboratory tests to be conducted:

• 18 samples will undergo Unconfined Compressive Strength ("UCS") testing. UCS tests the maximum axial compressive stress that a specimen can bear under zero confining stress. USC testing is a common test to understand the rock strength of a sample, and is widely used in geotechnical design for establishing an overall RMR for pit design;
• 8 samples will undergo Brazilian Tensile Strength testing. The Brazilian Test is a common laboratory test to indirectly determine a rock's tensile strength and is an important parameter in establishing a robust RMR for pit design. The Brazilian Test is the most widely used tensile strength test as the sample preparation and the testing procedure are efficient compared to other tensile strength tests;
• 8 samples will undergo Direct Shear Strength tests on a selection of common discontinuities to aid in the establishment of a robust RMR for pit design.

and the test works to be performed

Density and Magnetic Susceptibility
The samples sent for iron assay have been measured for density using the Archimedean method of weighing dry and then weighing submerged in water. The average density for the Fe mineralization in these holes can be seen in Table 1.

Magnetic susceptibility readings (Table 1) have been recorded on these samples providing an instant first-order understanding of the mineralogy of the iron bearing rocks being drilled. �Any magnetic susceptibility readings over 100 (x10-3) are considered high and indicate a high proportion of magnetite where magnetite is the dominant magnetitic and iron bearing component within the XIF.

About the XIF Project

• the project is located in the North-West District of Botswana and is proximate to the Namibian boarder and lies thirty (30) miles from the town of Divundu in Namibia. The Trans Caprivi Railway (TCR) line linking Zambia and Namibia is planned to pass through Divundu providing access to Walvis Bay, Namibia's deep-sea port. The project is also located within forty-three (43) miles of the proposed Mucusso line to Angola's Namibe Port;
• preliminary work on the Xaudum Iron project has defined a CIM compliant Inferred Mineral Resource Estimate of 441 million tonnes (Mt) with an average grade of 29.4% Fe, 41.0% SiO2, 6.1% Al2O3 and 0.3% P for the Block 1 magnetite XIF;
• Block 1 is a fraction of the potential XIF magnetite resource. An extrapolated exploration target has defined the XIF to be in the order of 5 to 7 billion tonnes at 15- 40% Fe. This exploration target was generated by inversion modelling of ground magnetic geophysical data which was compared and moderated to volumes from drilling data within Block 1 and its potential quantity and grade is conceptual in nature. To date, there has been insufficient exploration to define a mineral resource other than in Block 1 and it is uncertain if further exploration will result in the target being delineated as a mineral resource.� See, Press Release of 9/14/2014 on the Company's website for further details;
• metallurgical magnetic separation results (Davis Tube Recovery) show an average concentrate of 67.2% Fe, 4.2% SiO2, 0.5% Al2O3, 0.07% P is obtained at P80 grind size of 80 microns, although higher grades are possible at finer P80's. See, Press Release of 12/17/2013 on the Company's website;
• further exploration will be focused on Block 2 where the Company expects an increase in the resource;
• the XIF Project is a potential large and long-life Tier 1 mining project;
• the PEA will evaluate a number of options for development of the project at a variety of scales including:
• non-traditional but potentially profitable small-scale startup mining production options such as Ferrosilicon (FeSi) production from a magnetite concentrate,
• mid-size scenarios, whereby magnetite concentrate would be processed through a concentrator and transported to railhead and onto port facilities;
• large-scale mining options where full-scale mining would produce a magnetite concentrate processed by a concentrator plant with further potential modification to a pellet which would then be transported to port facilities;
• Botswana has significant coal reserves which can be a major advantage for the Xaudum Iron project, allowing for coal to be used in the beneficiation process to generate iron products such as iron pellets, sponge iron, pig iron, and also steel; and,
• the project would represent the first iron deposit to be considered for development in Botswana.� Gcwihaba has identified the project as having the potential to positively impact the future economy of Botswana as the country looks to diversify its economy, and help Botswana to reach its goal of moving away from a dependence on diamond revenues.
