StockMarketWire.com - Savannah Resources has received the preliminary metallurgical results for the Mahab 4 deposit in Block 5, Oman.

The deposit has a Current Indicated and Inferred JORC Mineral Resource of 1.51Mt at 2.1% copper.

Savannah is a 65% shareholder in Al Fairuz Mining, the holder of the Block 5 licence.

METALLURGICAL HIGHLIGHTS:

- Chalcopyrite identified as the sole copper bearing mineral, which is likely to lead to a simple, quick and relatively low cost flotation process to concentrate the copper ('Cu')

- Test data indicates that any potential development should enjoy favourable processing costs as the resource at Mahab 4 appears to be relatively soft and requires relatively low primary milling power requirements

- Test work also indicates relatively low equipment liner and grinding media wear due to low abrasion rates

- Initial rougher flotation test work indicated potential recoveries of around 95% at moderate grind sizes

- Rougher cleaner flotation at 38microns indicated that a saleable copper concentrate of over 23% can be achieved with recoveries over 90% with additional gold and silver credits

- There is potential to also produce a zinc product but further work is required to confirm that this is possible without affecting the copper grades and recoveries

- Additional test work is now underway to refine the process and to try and further improve the recoveries and overall copper concentrate grades.
