Savannah Resources Plc
Maiden 65 Million Tonne Inferred Mineral Resource - Jangamo Heavy Mineral Sands, Mozambique
Savannah Resources plc (AIM: SAV) announces that it has defined an initial, 65MT maiden Inferred Mineral Resource Estimate ("MRE") at its Jangamo Heavy Minerals Sand Project ("Jangamo") (Figure 1, Table 1). Jangamo is located in a world class heavy minerals sands province adjacent to Rio Tinto's major Mutamba mineral sands deposit in southern Mozambique.

Table 1: High Level Jangamo Mineral Resource Summary
· Initial resource drilling has successfully identified higher grade areas of THM mineralisation at or near surface
· A major Heavy Mineral Sands ("HMS") strandline system defined in the western part of the Jangamo tenement has excellent additional resource potential with intersections of up to 45m at 3.51% THM from 12m in JMRC133
· 2015 field programme in Mozambique is expected to start in March following the wet season with work to focus on expansion of the current resource base
Savannah's CEO, David Archer said, "We are delighted to announce a maiden Inferred Mineral Resource Estimate of 65Mt at 4.2% THM from a modest initial round of resource drilling over part of the eastern arm of the Jangamo tenement. The MRE provides us with a very solid resource base to build on with further resource drilling. The deposit we have identified is part of the very large Mutamba heavy mineral sands system with excellent potential to further expand the Mineral Resource in Savannah's tenement area. The Mineral Resource identified remains open along strike.
''We have also identified a major HMS system in the western part of the tenement with excellent intersections of up to 45m at 3.51%THM from 12m in JMRC133. The western system, which extends over at least 10km in strike, requires further exploration to be undertaken prior to resource drilling.
"Jangamo is part of a very large system and we are focused on defining a higher grade project that has superior economic characteristics for the development of a profitable mining operation with modest capital costs. Importantly, much of the Mineral Resource is from surface. This complements the favourable local infrastructure setting that benefits from nearby roads, power and port.
''We will now look to assess a number of promising commercial and strategic options for Jangamo following on from the definition of the maiden MRE. This is being done in parallel with the field programme in Mozambique which is expected to recommence in March following the wet season with work to focus on expansion of the current resource base."

Mineral Resource Estimate
Initial resource drilling was targeted at two areas within the eastern arm of the tenement to define the maiden MRE. The exploration target of the adjacent Mutamba deposit published in 2008 was 7-12Bn tonnes at 3-4.5% THM1. Savannah's strategy has been to target potential extensions of the Mutamba mineralisation into the Jangamo tenement, with a primary focus of defining mineralisation at the upper end of the grade range for the Mutamba deposit of over 4% THM.
The strategy has proved successful with a maiden Inferred MRE of 65Mt (52Mt net attributable to Savannah) at 4.2% THM at a cut-off grade of 2.5% THM being defined within the project area (Table 2, Figure 2). Details of the resource are contained in Appendix 1. The resource remains open along strike and there are a number of areas identified during the 2014 exploration programme which require follow up work and resource drilling.

Ongoing Resource Definition and Exploration Programme
Further work is now required to continue to build the current resource base and continue the ongoing exploration programme. The ongoing work programme will include:
· Metallurgical testwork to characterise the potential product from any project development
· Drilling around the newly defined Inferred Mineral Resource to further expand the resource base
· Further grid based resource drilling around anomalous exploration drill holes (Figure 3)
· Ongoing exploration work and resource drilling with a focus on the newly defined western dune system

Notes
Savannah Resources Plc (AIM: SAV) is a growth oriented, multi-commodity, exploration and development company. It has an 80% shareholding in Matilda Minerals Limitada which operates the Jangamo exploration project in a world class mineral sands province in Mozambique which borders Rio Tinto's Mutamba deposit, one of two major deposits Rio Tinto has defined in Mozambique, which collectively have an exploration target of 7-12Bn tonnes at 3-4.5% THM1 (published in 2008).
Savannah has interests in three copper projects in the highly prospective Semail Ophiolite Belt in Oman. The projects, which have an Indicated and Inferred Mineral Resource of 1.7Mt @ 2.2% copper and high grade intercepts of up to 56.35m at 6.21% Cu, provide Savannah with an excellent opportunity to potentially evolve into a mid-tier copper producer in a relatively short time frame. Together with its Omani partners, Savannah aims to outline further mineral resources to provide the critical mass for a central operating plant to develop the deposits.
In addition, Savannah owns a 19.7% strategic shareholding in Alecto Minerals Plc which provides Savannah with exposure to both the highly prospective Kossanto Gold Project in the prolific Kenieba inlier in Mali and also to the Wayu Boda and Aysid Meketel gold / base metal projects in Ethiopia for which Alecto has a joint venture with Centamin Plc. Under this joint venture, Centamin Plc is committing up to US$14m in exploration funding to earn up to 70% of each project.
