There are four main mining methods: underground, open surface (pit), placer, and in-situ mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits. Placer mining is used to sift out valuable metals from sediments in river channels, beach sands, or other environments.
The Chirano gold mine started production in October 2005 with a surface mining operation from three open pits. Surface operations stopped at the end of the second quarter of 2017. Since then, gold production is conducted from three underground mining operations.

(Coakley, 1999). Despite the economic potential of the mining industry in Ghana, mining output had decreased significantly since the late 1950‟s with gold experiencing the most dramatic decline in production. As Aryee (2001) puts it “For four decades up to the 1980‟s no new mine was opened in Ghana due to a myriad of problems

Summary. Historically, the majority of gold was mined from "placer deposits", where gold has settled out of an existing or ancient waterway downstream of where nuggets had eroded out of rock outcrops.Some early miners also used an early form of hardrock mining, digging solid veins of gold out of rock, where mineralized water had deposited it over thousands of years.
