Lydian Reports Positive Results From Further Column Leach Metallurgical Tests; 93% Recoveries At 19mm Optimal Crush Size

Exceptionally rapid leaching reported with up to 80% of gold recovered after seven days

TORONTO, Ontario, January 17, 2011 – Lydian International Ltd. (TSX: LYD) (“Lydian” or “the Company”), a gold-focused mineral exploration and development company, today announced results of further metallurgical testing from its Amulsar gold discovery in Armenia. Amulsar is a high-sulfidation style gold project which currently hosts a CIM compliant Inferred Category Resource of 1.4 million ounces at 0.9g/t gold.

Lydian commissioned Wardell Armstrong International to undertake a further program of laboratory bottle roll and column leach test work on drill hole samples from the Amulsar project. Composite samples (samples A and B) originally tested by SGS Minerals Services UK Ltd (see press release 17th March 2010) were re-tested using a wider range of crush sizes and solvent concentrations. A representative head-grade sample was riffled from each composite and assayed for gold. Sample A assayed 1.26g/t gold and Sample B assayed 1.14g/t gold. The program of column test work was undertaken using solvent concentrations of 0.075, 0.050 and 0.025%. The crush sizes investigated were 38, 25, 19 and 12mm. The columns were irrigated at a rate of 10 litres/m2/h and the leach period was 68 days.

The test results concluded that the cost-optimized crush size for Amulsar gold mineralization is probably 19mm and the optimum solvent concentration is 0.05%. Using these parameters composite’s A and B recovered 93.5% and 93.1% gold respectively. Initial column leaching was exceptionally rapid for both samples with up to 80% gold being recovered after seven days of leaching (see Table and Figure in Appendix).

“Good metallurgical recoveries are of course a critical ingredient in the overall economics of a profitable gold mine” said Tim Coughlin Lydian’s President and CEO “By virtue of its deep oxidation the Amulsar project has always demonstrated very good gold recoveries. Also important, but often overlooked, is the time it takes to extract the gold and as with previous results, these tests imply exceptionally rapid recoveries for Amulsar. Further metallurgical tests are currently being conducted on fit for purpose wide diameter drill core with results expected early in Q2”
