Executive Summary
This NI 43-101 Technical Report details the Songxian Property in Henan Province, China, acquired by Silvercorp Metals Inc. in late 2011. The property includes two underground mines, XHP and XBG, with commodities including gold, silver, lead, and zinc. The XHP mine operates the Shi-Tong-Gou Mill Flotation Plant (Plant 1), which was modified in 2012 to process lead-zinc mineralization. The XBG mine operates the Xi-Bai-Gou Lead-Zinc Processing Plant (Plant 2), which was shut down in 2011.
Mining utilizes shrinkage stoping with underground access via adits and declines. The processing plant at XHP has a design capacity of 400 tonnes per day. Metallurgical testing highlights challenges with ore grade and liberation due to fine intergrowths of galena and sphalerite, impacting concentrate grades and recoveries. The report outlines exploration recommendations, infrastructure details including tailings management facilities, and safety considerations aligned with Chinese regulations.
