Name: Prestea mine.

Location: The mine is adjacent to the town of Prestea, in western Ghana.

Mine Owner/s: Golden Star Resources (90%) and the Ghana government (10%).

Brief Description: Prestea comprises the Prestea mine, the Prestea openpits, which ceased operations in the second quarter of 2020, and associated support facilities.

Brief History: The Prestea underground mine was operated from the 1870s until 2002, when mining ceased following an extended period of low gold prices in the late 1990s and early 2000s.

Previously, production was being delivered from the Prestea openpits and the Prestea underground gold mine. In the second half of 2018, Prestea became an underground-focused operation.

Primary Metals/Minerals: Gold.

Secondary Metals/Minerals: Not stated.

Geology/Mineralisation: Banded quartz vein associated with abundant free gold, pyrite and minor arsenopyrite.

Reserves: Total proven and probable reserves as at December 31, 2019, were estimated at 856 000 t grading at 11 g/t of gold.

Resources: Total measured and indicated resources as at December 31, 2020, were estimated at 1.14-million tonnes grading at 17.15 g/t of gold. Inferred resources have been estimated at 2.49-million tonnes grading at 1.5 g/t of gold.

Mining Method: Mechanised shrinkage mining (Alimak) is being used on the mine’s 24 Level. Golden Star is expected to introduce longhole stoping on 17 Level of the operation from the fourth quarter of 2020.

Major Infrastructure and Equipment: Prestea has a carbon-in-leach processing facility, with a capacity of up to 1.5-million tonnes a year, located 14 km away at Bogoso, which is suitable for treating nonrefractory gold ore.

Prospects: The Prestea underground mine has exploration upside through the extension and definition of the West reef orebody, with the objective of increasing the supply of high-grade ore to the processing plant in the near term.

Other focuses of the exploration programme include the initial testing of the Main reef and South Gap areas, which have the potential to add ore to the mine plan in the medium to long term.
