Amulsar is a completely new gold discovery and was discovered in 2006. During 2006 and 2007 initial soil geochemical analyses identified an area of 3.5km by 0.5km which became the focus for future drilling. Further infil soil sampling was undertaken in 2010 and increased the area of gold mineralization to 3.6 km by at-least km. The soil data clearly identified the Tigranes, Artavasdes and Erato target areas as well as identifying further drilling targets and extensions.
Amulsar is a high-sulphidation, epithermal-type gold deposit. Lydian commenced drilling on Amulsar in 2007 and by March 2009 a maiden inferred resource of 1M ounces was released. This was increased in to 1.4M ounces of inferred resource in March 2010. In April 2011 the resource was increased further to 32.4 Mt at 1.1 g/t Au (1.1 million ounces) of Indicated Category resources and 48.3 Mt at 0.9 g/t Au (1.4 million ounces) of Inferred Category.
In 2007 five scout diamond drill holes totalling 593m were drilled. These were followed in 2008 by a further 18 diamond holes and 74 RC holes totalling 13,048m (2685m diamond, 10,363m RC). During 2009 Lydian drilled a further 8 diamond holes and 101 RC holes totalling 13,536m (1090m diamond, 12,446m RC). The 2010 drilling season proved to be very successful with 60 diamond holes and 129 RC holes being completed totalling 25,322m, which included metallurgical and water monitoring holes (8,286m diamond, 17,036m RC).
Lydian’s drilling campaigns since 2007 have now defined a robust resource area on Tigranes and Artavasdes which has the potential to form a large open pit mining operation. The drilling has also outlined a further area of mineralisation at Erato. The structural and geological trends identified from drilling and surface mapping, combined with the soil geochemistry, have outlined further significant exploration potential, particularly in the Tigranes North, Tigranes East, Artavasdes West, Artavasdes South and Arshak areas (see map). All of these areas were targeted as part of the 40,000 meter drilling program that was completed in 2011.
