Savannah Resources Plc

Metallurgical test work Confirms that High Quality Saleable Quartz and Feldspar Products can be Generated as a Co-product with Spodumene Lithium

Mina do Barroso Lithium Project

Savannah Resources plc (AIM: SAV, FWB: SAV and SWB: SAV) ('Savannah' or the 'Company'), the AIM quoted resource development company, which is focused on becoming Europe's most significant producer of lithium spodumene concentrates from its Portuguese Mina do Barroso Project ('Mina do Barroso', 'MdB' or 'the Project'), is pleased to announce that its ongoing metallurgical test work has successfully produced saleable quartz and feldspar products. To view the press release with the illustrative maps and diagrams please use the following link: http://www.rns-pdf.londonstockexchange.com/rns/3197K_1-2018-12-12.pdf

Highlights

· High quality, saleable quartz and feldspar co-products produced from ongoing metallurgical test work programme

· Co-products will be produced from further processing of the tail material from the spodumene concentration process

· Initial indications are that the following products can be produced and market studies by First Test Minerals have been completed to provide some indicative pricings for the products:

- Feldspar (Na2O+K2O+Li2O grades >12%) potential price range of US$65-100/tonne

- Quartz (99.6% pure) potential price range US$60-100/tonne

- Bulk Tail (Na2O+K2O+Li2O grades >7%) potential price range of US$40-45/tonne

- All products have low levels of potential impurities, below maximum limits specified by customers

· Importantly, the potential pricing of the products which can be produced have been identified as being significantly higher, by First Test Minerals, than those conservative values used in the recent Scoping Study of US$39/tonne for feldspar and US$33/tonne for quartz

· Test work for co-product and specifications independently evaluated and confirmed by ceramics industry expert, First Test Minerals Ltd

· Bulk co-products currently being generated for further evaluation by potential customers and preliminary offtake discussions are underway with a number of potential parties

· Significant environmental benefit from the sale of co-products, reducing the potential size of the footprint of any potential operation

· Sale of co-products to prove economically beneficial for the Company, through the diversification of asset products

Savannah's CEO, David Archer said: "The area in which we operate is a major quarrying region for ceramic materials which supply the vibrant ceramics industries in both Portugal and Spain. Importantly, having multiple product streams means we are maximising the value adding potential of the Project while also reducing the volume of non-saleable material that will need to be emplaced on site in contoured and vegetated landforms. I look forward to providing further updates as we progress our Feasibility Study towards delivery in 2019."

Environmental Advantages

The production of quartz and feldspar products for the ceramics industry will mean that the Company will reduce the volumes of non-saleable material that will need to be emplaced on site in contoured and vegetated landforms. This is a very positive outcome and is part of Savannah's ongoing commitment to design a project which minimises any potential environmental impacts.

Details of Metallurgical Test Work Programme

Savannah has completed a series of floatation tests on a bulk sample of pegmatite material from the Mina do Barroso project which has successfully generated saleable feldspar and quartz co-products in batch test work. Further bulk test work is planned to produce bulk mica, feldspar and quartz samples for evaluation by potential customers.

The test work was managed by Savannah's owners' team representatives, with the results evaluated by First Test Minerals ('First Test') which is an independent consultancy with significant experience in the ceramics and glass industry who deal with the raw products (such as feldspar and quartz) that are currently used in these industries. First Test conducted a review of the current market based on the product specifications to generate the pricing ranges for the various products generated.

Feldspar

The feldspar concentrate produced from the floatation test work contains Na2O+K2O+Li2O grades >12% (Table 1 and Figure 1) which First Test have advised has the potential to be used in tableware, glaze, sanitaryware and glass. Penalty elements in the feldspar concentrate, such as iron, were below the limits specified by customers. First Test's analysis shows this feldspar product has the potential to sell from US$65-100/tonne depending primarily on final grind size.

Quartz

The quartz concentrate produced has an SiO2 grade of 99.6% which First Test stated has the potential to be used in ceramics and glass (Table 2 and Figure 2). Penalty elements in the quartz concentrate, such as iron, were below the limits specified by customers for a number of applications. First Test's analysis shows this quartz product has the potential to sell from US$60-100 /tonne, depending primarily on final grind size, with further upside on increased grade product.

Combined Tailings Product

Savannah also has the option of selling its tailings (combined feldspar and quartz concentrate) without further upgrading or processing (Table 3) at a potential price of US$40-45 / tonne.

Table 3. Combined feldspar / quartz tailings chemical grades are shown below.

Potential Product Pricing

Conservative feldspar and quartz prices of US$39/tonne and US$33/tonne respectively were used by the Company during the Scoping Study, prior to Savannah generating saleable co-products and engaging First Test. This recent test work has highlighted the significant potential upside of the co-products with initial market reviews conducted by First Test of the product specifications indicating:

- Feldspar (Na2O+K2O+Li2O grades >12%) potential price range of US$65-100/tonne

- Quartz (99.6% pure) potential price range US$60-100/tonne

- Bulk Tail (Na2O+K2O+Li2O grades >7%) potential price range of US$40-45/tonne

Further Work

Work is continuing to further evaluate and develop the potential co-products from the production of the spodumene concentrate. This work programme includes:

· Bulk test work to generate samples of each of these co-products for customer evaluation

· Further evaluation on the potential for a mica co-product is underway to determine its suitability for its use as a building material like cements for plasterboard. Initial research by the Company suggests these products can be valued at over US$500/t

· A trade-off study to confirm potential sale quantities of the individual products along with expected capital and operating costs to generate the individual co-products is currently underway

· Preliminary discussions with potential offtake partners to better understand the size of the market and customer needs is also underway
