Gold Mineralisation Identified within Block 4, Semail Ophiolite Belt, Oman
Savannah Resources plc (AIM: SAV) ('Savannah' or the 'Company') is pleased to announce that it has identified areas of gold mineralisation with associated copper mineralisation at Block 4 in Oman. The results follow a recently completed rock chipping and geological mapping programme at Block 4. To view the press release with the illustrative maps and diagrams please use the following link:

HIGHLIGHTS:
· Reconnaissance mapping and rock chip sampling within Block 4 has identified a series of anomalies with high levels of gold mineralisation associated with copper mineralisation
· Rock chip sampling produced results up to 5.7% copper and 3.7g/t gold (not from same rock sample) with a large number of the anomalous samples being returned from the Gaddamah prospect in Block 4
· Prospectivity of Gaddamah prospect in Block 4 also highlighted by historical drill intercept of 15.9m @1.91 g/t gold and 1.2% copper from BEC23
· Diamond drilling is underway at both the Sarami (Block 5) and Ghayth (Block 4) prospects with five of the planned 10 hole diamond drill programme completed to date. A further update on the programme will be provided in coming weeks once it has been completed.
· Semail Ophiolite belt is proven to host clusters of relatively high grade copper deposits with gold credits and metallurgically simple ores
Savannah's CEO, David Archer said, "Work is progressing well on our Blocks 4, 5 and 6 projects with the primary focus being on VMS style copper deposits. Recent results demonstrate there are also high levels of gold anomalism present, which is highly exciting and can often be found with copper mineralisation in addition to being prospective in its own right. We see these unexplained gold anomalies, especially Gaddamah, which is located close to the old Lasail (9.2Mt at 1.6% copper) and Lasail West (0.4Mt at 1.0% copper) copper mines, as significant opportunities and we intend to analyse and evaluate these prospects further over the coming months.
"Our review and analysis of the historical database has highlighted many gold occurrences throughout the Semail Ophiolite belt, many of which have not been followed up or their significance fully understood."
Geological Mapping and Rock Chip Sampling Programme
Initial work has focused on the Gaddamah, Zuha and Ghayth prospects in Block 4 with reconnaissance mapping and sampling completed over each prospect with a total of 22 rock chip samples collected (Table 1).
Results from these 22 rock chip samples returned some encouraging results with some particularly elevated gold results obtained, especially from the Gaddamah Prospect.
Samples collected at Gaddamah returned encouraging anomalous results with a maximum copper result of 5.7% and a maximum gold result of 3.7g/t gold (not from same rock sample). Of particular interest at Gaddamah was the concentration of gold rich values within the western area of the prospect.
Rock chip samples from the Zuha prospect around the main gossan have returned a number of elevated results ranging between 0.5% copper to a maximum value of 2.9% copper, confirming past work, together with elevated gold up to 0.59 g/t Au also returned.
Sampling at the Ghayth prospect failed to return any significant results.

Table 1. Summary of Results from Rock Chipping Programme
Rock chips were assayed via the following method
· The tested samples were dried at 85°C, crushed and pulverized to 75 μm.
· The method for gold analysis was using was fire assay (using 30g samples) with an atomic absorption spectrometry (AAS) finish, which detected gold in the range of 5ppb - 10ppm. A re-assay with gravimetric finish was used when the initial assay detected >10ppm gold (and silver) using a further 30g sample.
· The method for copper analysis was a 24 element inductively coupled plasma optical emission spectrometry (ICP-OES) analysis of an Aqua Regia digest.

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. On 31 December 2014 Savannah announced maiden, 65Mt Inferred Mineral Resource @4.2% total heavy minerals ("THM") at a 2.5% cut-off grade for Jangamo The project is located 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% THM (published in 2008).
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 @ 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.
