The Gold Ridge Mine, Guadalcanal, Solomon Islands
Gold Ridge hosts around 1.4 million ounces of epithermal volcanic-hosted gold. Ross Mining NL began the construction of Solomon Islands' first gold mine in 1997 and operated a highly successful gold mine between 1997 and 2000, when ethnic tensions (unrelated to the mine) closed the operations.Web

Mine Planning and the Crucial Role of Geology
Abstract. Mine planning is the process that determines the way in which an ore deposit will be mined over the life of a mining operation. It necessarily draws on everything that planning engineers believe will determine the ultimate success of the proposed mine and uses as its foundation all of the geology-related data on the deposit.Web
