· Land access and initial forestry permits in place for development, with new permit applications in process.
· Metallurgical testwork yields an average gold recovery of 88.5%.
· Approximately 16,000 tonnes of gold mineralised material are stockpiled, with future potential to truck to the Kiziltepe plant.

Three samples of clay altered andesite from Ivrindi were used for metallurgical testwork, at grades of 4.30, 3.50 and 0.47 g/t Au. These samples were pulverised to -75 micron and then subjected to similar leach conditions as utilised within the Kiziltepe processing plant. An NaCN concentration of 1,000 mg/lt was used for this testwork rather than a 2,200 mg/lt concentration currently used in the Kiziltepe processing plant. Gold recoveries were high and varied between 85.1% and 91.4%, with the lower recoveries associated with lower grade ore. Maximum recovery of gold was achieved for the samples after 72 hours.
Trial mining was conducted on the project area in recent years as specified in statutory submissions to the Turkish Government and in accordance with project reporting requirements. To date, approximately 16,000 tonnes of mineralised material was extracted from the trial mining area at an average grade of 1.2 g/t Au. Consideration is being given to trucking some of this material for processing at the Kiziltepe mine site in the future.
Details of the
At Ivrindi, mineralisation occurs at the Kinik prospect, which occurs within a 450m long zone of mineralised alteration within Miocene age andesitic volcanic rocks. Mineralisation extends from surface to 70m vertical depth and is developed in part along the normal faulted contact with Permo-Triassic age limestones. The gold mineralisation is most well developed in several intensely clay altered zones associated with haematite and limonite, in which quartz vein formation is virtually absent.

Trial mining commenced within the central part of the resource area during 2018. Further trial mining will be conducted in the 2020/21 period. The project is expected to be within economic trucking distance from the Kiziltepe operation and is accessible via asphalt road, which includes lengthy sections of dual carriageway. Consequently, any potentially open-pittable resources identified at Ivrindi are expected to be trucked efficiently to the plant site at Kiziltepe.

"Inferred resource" a part of a mineral resource for which tonnage, grade and mineral content can be estimated with a low level of confidence. It is inferred from geological evidence and has assumed, but not verified, geological and/or grade continuity. It is based on information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes that may be limited or of uncertain quality and reliability;
