Lydian Reports Positive Metallurgical Test Results From the Amulsar Gold Project, Armenia

TORONTO, ONTARIO--(Marketwired - Oct 22, 2013) - Lydian International Ltd. (TSX:LYD) ("Lydian" or "the Company"), a gold-focused mineral exploration and development company, announces the results of cyanide bottle roll tests and column leach tests on sample composites from the Erato pit at its Amulsar gold project in Armenia. The results returned gold recoveries ranging from 88% to 95% in this phase of work. In addition, the results from a cold climate test showed only a minor reduction in the rate of recovery and that overall gold recovery was not affected by a cold temperature.

The tests consisted of further confirmation testing for the Amulsar gold project, and were conducted on sample metallurgical composites from four drill holes from the Erato deposit at the Company's Amulsar gold project (see Figure 1 in appendix). The samples were used for test work that included head analyses, head screen analyses with assays by size fraction (crushed to 100% passing 12.5 millimeters), bottle roll leach test work, cyanide soluble analyses, and column leach test work. In addition to these samples, portions of previously tested core material from the Tigranes/Artavasdes deposits were combined to generate a single composite, which was used to test the metallurgical effects of "cold climate" leach kinetics. All of the test work referenced herein was performed by Kappes, Cassidy & Associates (KCA) at its metallurgical laboratory located in Reno, Nevada.

As part of the test work requirements for Erato, KCA carried out a metallurgical test work program consisting of fine cyanidation bottle roll leach (simulating conventional CIL), and column leach tests (simulating heap leaching). The program was conducted on master composites prepared from selected intervals taken from half core, representing Erato drill holes located within the starter and final pit shells.

The fine bottle roll cyanidation leach tests were conducted at 80% passing 75µm. Cyanide bottle roll tests were completed on crushed portions of each sample. Each leach test was run for a period of ninety-six hours with solution sampling performed at 2, 4, 8, 24, 48, 72 and 96 hours.

Results of the fine bottle roll cyanidation leach tests are summarized in Table 1.

Table 1: Fine Cyanidation Leach Tests

Table 1 shows the bottle roll leach test work with gold extractions ranging from 94% to 97% based on calculated heads which ranged from 0.710 to 1.241 grams per metric tonne. Consumption of both sodium cyanide and the blended hydrated lime were low throughout.

The results from the column leach test work are summarized in Table 2.

Table 2: KCA - Column Leach Tests

Table 2 shows results for the column leach test work, gold extraction ranged from 88% to 95% (see Figure 2 in appendix). When refrigerated at a temperature of 3°C, sample number 62544A had an average extraction time of 73 days, 14 days longer than the similar column tests conducted at ambient temperature. However, although the colder temperature resulted in slower leach kinetics, the final gold leach recovery was eventually the same for columns conducted at 3°C as those conducted at ambient temperature. Management of the Company believes that this result provides further support for its determination that a heap leach recovery method is appropriate for the Amulsar gold project.

These results are consistent with previous work conducted by the company and demonstrate that, although the leach performance at Amulsar will vary depending on the climatic conditions, ultimate recovery appears to be independent of temperature. The tests suggest that leach kinetics would slow in winter and then rise in the spring as the temperature increases, providing a "slug" of gold from the heap in the spring, ultimately resulting in approximately the same leach recovery point as determined by column leach tests conducted at constant ambient temperature.

Marc Leduc, Chief Operating Officer of the Company, commented "The latest metallurgical results reinforce the suitability of the Company's current Amulsar project model, including the use of heap leach technology. We are now focused on incorporating these latest results and lower reagent consumption rates in an updated feasibility study that is targeted for completion in the second quarter of 2014."
