ASX RELEASE                                           26 AUGUST 2008

 

Encouraging Kunche Metallurgical Results

 

Overall Gold Recovery Expected To Exceed 90%

With Up To 40% Recoverable By Gravity

 

West African gold explorer Azumah Resources Limited (ASX: AZM) is pleased to announce results from the first stage of metallurgical test work being conducted on samples of primary (unoxidised) mineralisation from the Kunche resource at the Company's 100% owned Wa-Lawra Gold Project in Ghana.

 

Initial metallurgical results indicate that recoveries of over 90% should be obtained on typical resource-grade Kunche mineralisation using conventional gold processing technology comprising gravity separation followed by carbon-in-leach ("CIL").

 

Importantly, between 25% and 40% of the gold is likely to be recoverable using a preliminary gravity separation phase, which should impact favourably on bottom line operating costs.

 

The first stage of this laboratory scale test work was undertaken in Perth by independent metallurgical laboratory, AMDEL Ltd, on a blend of ore and marginal grade material grading approximately 1.0g/t gold.  The test results returned a total gold recovery of 86.5% (grind size of 80% passing 75�m, final solid tail of 0.12 g/t Au), of which approximately 40% was recovered by gravity separation (Table 1).

 

"Whilst a number of gold operations in Ghana are burdened with refractory ores requiring expensive specialist treatment regimes, it is particularly encouraging that Kunche mineralisation can be treated using conventional gold processing technology - especially as 72% of the total 516,000 ounce indicated and inferred gold resource at Kunche is comprised of primary, unoxidised mineralisation," commented Azumah Executive Chairman, Mr Stephen Stone.

 

"The next phase of test work is already underway focused on Kunche mineralisation grading closer to the average combined indicated and inferred resource grade of 1.9g/t gold," Mr Stone continued.  "Metallurgical test work will also be conducted on samples of primary mineralisation from the recently discovered Bepkong deposit, for which we expect to release a maiden JORC compliant resource estimate shortly."

Notes:

1.        Kunche sample prepared from � core by combining marginal and ore grade intervals from drill holes KRCD018 and KRDC136.

2.        Gravity separation conducted in a laboratory scale Knelson concentrator with the tail collected for CIL testing and the concentrate amalgamated with mercury and assayed.

3.        CIL tests conducted in Perth tap water for 48 hours at 40% solids (w/w), a carbon concentration of approximately 15g/l and an initial cyanide concentration of 500mg/l. The pH was maintained at 10 and dissolved oxygen levels ranged between 8 and 10mg/l.
