Anomalous Lithium Identified on Finland Projects
Savannah Resources plc (AIM: SAV) ('Savannah' or 'the Company'), the AIM quoted resource development company, announces that reconnaissance rockchip sampling over its new lithium projects in Finland, Somero and Erajarvi, has returned anomalous lithium results. To view the press release with the illustrative maps and diagrams please use the following link:
http://www.rns-pdf.londonstockexchange.com/rns/2224J_-2016-9-7.pdf
HIGHLIGHTS:
-- 4 weeks of an 8-10 week reconnaissance geological mapping and rockchip sampling programme has been completed
-- A total of 70 rockchip samples have been collected to date and submitted to the laboratory for analysis, with 3 assay results returned to date
-- Initial analysis, geological mapping and rock chip sampling has highlighted:
o Somero Project has prospective pegmatites up to 1,200m long and 50m wide with an initial rockchip assay of 4% lithium oxide ('Li(2) O')
o Erajarvi Project has prospective pegmatites up to 800m long and 30m wide with an initial rockchip assay of 1.29% Li(2) O
-- Key lithium minerals petalite, spodumene and lepidolite were all identified in hand specimens
-- The remaining assays are expected to be received over the next four to six weeks and the results will be announced as soon as practicable thereafter
-- Finland is one of the most prospective countries on mainland Europe for potential lithium discoveries. Both project areas have excellent access to high quality infrastructure and are located close to potential final customers
David Archer, Savannah's Chief Executive Officer said today, "We are very pleased that this early work is already confirming both encouraging grades and defining significant pegmatites at surface containing key lithium minerals. Finland is a lithium focus for a number of companies, both because of its excellent mining legislation and its infrastructure endowment. These initial results are promising and we keenly await the next set of results."

SOMERO LITHIUM PROJECT
Savannah's Somero Reservation (Figure 2) is located less than 2km south of TSX listed Nortec Minerals' Kietyonmaki and Hirvikalio lithium deposits, which were drilled by the GTK (Finnish Government Department). Historical geological mapping of the area has confirmed the presence of 56 pegmatites, some with the lithium minerals petalite and spodumene, but no geochemical sampling had been completed to date. Recent work completed by Savannah focusing on these pegmatites has highlighted a series of pegmatites up to 1.2km in length and 50m wide, with some of the pegmatites like the Torkkomaki prospect containing massive zones of petalite, which has returned a high-grade lithium assay result of 4% Li(2) O (Figure 3). A total of 70 rock chip samples were collected and submitted for analysis and to date three assays have been returned.

ERAJARVI LITHIUM PROJECT
The Erajarvi Project (Figure 4) reservation covers a swarm of at least 61 known pegmatites that have been mapped in the area, but to date no geochemical sampling has been conducted. Preliminary mapping indicates that the potential lithium bearing pegmatites are in the contacts of the granite plutons or in the schists close to the contacts, with larger pegmatites over 10m wide generally not encountered farther than 1.5km from the granites.
The larger pegmatites in the region include Niemelä pegmatite, which is up to 30m wide and at least 800m long) and Vitaniemi, which is at least 400m in strike, over 100m in width, 10m in thickness and open in all directions. The prospectivity of these pegmatites was confirmed in the recent mapping and sampling program with abundant lithium minerals spodumene, lepidolite, petalite identified in the Vitaniemi pegmatite and a sample collected from here assaying 1.29%Li(2) O (Figure 5).
Further detailed mapping and systematic sampling of the Erajarvi reservation is now underway, with this work expected to take at least four weeks.

Notes
Savannah Resources Plc (AIM: SAV) is a growth oriented, multi-commodity, development company:
Oman
Savannah has interests in three copper blocks in the highly prospective Semail Ophiolite Belt in Oman. The projects, which have an Indicated and Inferred Mineral Resource of 1.7Mt at a grade of 2.2% copper and high grade intercepts of up to 56.35m at a grade of 6.21% Cu, with additional gold upside potential, provide Savannah with an excellent opportunity to potentially evolve into a mid-tier copper and gold 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, and in December 2015 outlined exploration targets of between 10,700,000 and 29,250,000 tonnes grading between 1.4% and 2.4% copper.
Mozambique
Savannah has agreed to acquire 100% of Matilda Minerals Limitada which currently operates the Jangamo exploration project, and has agreed with Rio Tinto to form a joint venture in Mozambique to develop the combined Mutamba/Jangamo Project. Formation of the joint venture remains subject to approval by the Ministry of Mineral Resources and Energy of the Republic of Mozambique. Jangamo has a 65Mt Inferred Mineral Resource at a grade of 4.2% total heavy minerals ("THM") at a 2.5% cut-off grade. The Mutamba, Dongane and Chilubane deposits have a combined exploration target of 7-12Bn tonnes at a grade of 3-4.5% THM (published in 2008).
Finland
Savannah has registered applications over two new lithium projects, Somero and Erajarvi, covering an area of 159km(2) in Finland. Savannah holds a 100% interest in these projects through its Finnish subsidiary Finkallio Oy. Geological mapping by the Finnish Government within the project areas has highlighted the presence of lithium minerals spodumene, lepidolite and petalite with the Government also identifying Somero and Erajarvi as one of the most prospective areas to discover lithium deposits in Finland. Savannah plans to initiate an exploration programme including data compilation, geological mapping and surface sampling with the aim of generating drill ready targets during 2016.
