The Ulaan Ovoo Coal Mine is an operating surface coal mine in Tüshig, Mongolia. The Ulaan Ovoo mine is an open-cut coal mine in Mongolia owned by Prophecy Coal Corp., a Canadian mining company.[4]

According to the website of mine owner Prophecy Coal, "Exploration drilling work was performed on the deposit during the late 1970s by the Mongolian Ministry of Geology and Energy and again from 1993-1997 by Erdenet, a Mongolian-Russian joint venture mining and processing company."[4]

In 2006, Red Hill (predecessor to Prophecy) estimated the mine area had 174 million tonnes of measured resources, 34 million tonnes of indicated category, and 36 million tonnes of inferred. Production began in 2010. The coal is trucked 120km to to the Sukhbaatar rail siding, which is then is transported by rail to Russian and Mongolian customers.[4][5]

Prophecy produced approximately 500,000 tons of coal between 2012 and 2014 from the mine before putting the mine on standby. The company made deliveries from the mine between 2016 and 2017 to select customers. An undisclosed lessee company entered a lease agreement with Prophecy in October 2018 to operate the mine, which is valid for three years. Mining activity was resumed at the site in March 2019, following the signing of the agreement.[8] However, operations at the mine briefly stopped in April and May due to the late approval of the environmental plan, which wasn't issued until June 2019.[9]

Mine ownership

The mine was owned by Mongolia Mid Asia International (MMAI) until 2005, followed by Red Hill until 2010. Prophecy Development Corporation assumed 100% ownership of the project in 2010.[8]

In March 2020, Prophecy Coal renamed itself Silver Elephant Mining Corp.[10][6]
