High Grade Copper Mineralisation Identified at the Aarja Prospect

Block 4, Semail Ophiolite Belt, Oman

Savannah Resources (LSE:SAV) has identified new high grade copper mineralisation on at the Aarja Prospect at its Block 4 permit following a detailed collation of historical data. The copper mineralisation is located along strike and under the previously mined Aarja pit.

Savannah is earning a 65% shareholding in the Omani company, Al Thuraya LLC, the owner of the Block 4 Project. To view the press release with the illustrative maps and diagrams please use the following link:

HIGHLIGHTS:

· New copper mineralisation model produced for the Aarja Main, Dogs Bone and Aarja South Zones demonstrating high grade copper mineralisation under the Aarja pit and along strike
· Newly identified, historic high grade results (Appendix 1) include:

o Aarja Main – 18.58m at 4.7% copper from 143m (hole 10-23)

– 24m at 3% copper from 143.5m (hole 10-82)
– 20m at 2.5% copper from 144m (hole 10-80)

o Dog’s Bone – 33.8m at 3.35% copper from 153.1m (hole AEX-39)

– 10m at 4.17% copper and 2.43% zinc from 100.5m (hole AEX-31)
– 7.8m at 6.77% copper from 116.1m (hole AEX-11)
– 5.05m at 8.49% copper and 2.86% zinc from 130.9m (hole AEX-42)

o Aarja South – 9.8m at 3.86% copper from 224m (hole AEX-36)

· A trench previously completed by Savannah over an outcropping gossan to the immediate south of the main Aarja pit (14.5m at 8.03g/t gold and 0.9% copper) suggest the potential to expand the pit to the south (Appendix 2)
· A series of holes will be drilled to confirm the historic results prior to the calculation of a JORC compliant mineral resource estimate, targeted during Q4 2015
· The existing open pit and underground development allows access to the copper mineralisation

Savannah’s CEO, David Archer said, “Savannah, together with our partners Al Thuraya, are very encouraged by these results from the compilation of the historic data at the Aarja Prospect at Block 4. Whilst work is still continuing in finalising this model, the early signs point towards a significant zone of copper mineralisation being present under the Aarja pit and along strike. Following completion of the data compilation and interpretation, we will look to complete some confirmatory drilling to verify the historical data as much of the previous drilling was undertaken in the 1980’s. Should our drilling verify the historical data, we plan to complete a maiden JORC compliant mineral resource estimate before the end of the 2015 calendar year.

“The existing open pit and underground development which access the copper mineralisation may allow for a rapid, low cost mine development, but further work is required to confirm this. These results continue to support Savannah’s view that Oman is a first class destination for copper VMS mineralisation, with excellent infrastructure coupled with a low cost setting, making Oman a compelling investment location.”

Historic Data Compilation

An outline of copper mineralisation has been completed for the Aarja Prospect based on historical drill data collected between 1975 and 1994. A total of 84 holes are known to have been drilled into the Aarja Prospect. To date assay and lithological data for 64 holes has been located and digitised. All the historic holes were completed using diamond coring with samples collected based on geological intervals and assayed for copper by AAS in laboratories in Canada and Oman.

Three dimensional wireframes of the mineralisation were constructed based on geological logging and a nominal 0.5% Cu cut-off grade. The next steps will be to undertake some confirmatory drilling to verify the copper mineralisation model and subsequently generate a maiden JORC compliant mineral resource estimate.

Trench Sampling

Trench sampling was recently undertaken by Savannah across a large gossan at the southern end of the Aarja pit to test for copper and gold mineralisation. The results have demonstrated a broad zone of high grade gold and copper mineralisation, returning 14.5m at 8.03g/t gold and 0.9% copper. Further sampling is now required to assess the extent and tenor of the mineralisation.
