Lane Xang Minerals Limited (LXML) is proposing to recommence and expand gold mining and processing at the Sepon Mine site in Vilabouly District, Savannakhet Province, Lao PDR (Figure I).LXML is the registered name of the company which operates the Sepon Mine, in which Chifeng Gold own a 90% interest and the Government of the Lao PDR (GoL) owns 10%.LXML has been operating the Sepon Project since initial approval was granted by the GoL in 2002.


The Mineral Exploration and Production Agreement (MEPA) was signed in 1993 and covers an area of 1,250km2 in Vilabouly District, Savannakhet Province.The Greater Project Development Area (GPDA) lies within the MEPA and was characterized in an ESIA approved by the GoL in 2006 (as part of the approval for the Western Tailings Storage Facility WTSF).The GPDA, in which the Project is situated, lies in a lowland area between the Annamite Ranges to the east and the sandstone range of the Phou Xang He to the south and south west.Elevation within the GPDA ranges from 200m to 700m above sea level.The region is within the Mekong River catchment, with the major river of the area being the Nam Kok, which flows into the Xe Bang Hiang; a significant tributary of the Mekong.


Based on the current mine plan, Sepon’s copper production will finish towards the end of 2020, with transition to the gold operations expected to extend the Sepon mine life to 2028.The gold plant is designed to treat 2.5Mtpa of gold ore (both primary – 1.5Mtpa and oxide – 1.0Mtpa). Any shortfall in primary ore will be made up with oxide ore.
