The oxidized mineral range penetrates up to 70 m deep at a range between 1m and 10 m breadth. Drilling could conceivably reveal a very rich gold deposit. The company operates two large bucket dredges for excavation and a large suction dredge for stripping of the overburden at sediments. Gravel is screened by trommel and reported to Yuba jigs for concentration in two stages. Diamond and gold are trucked to headquarters for attrition grinding in bell mills.
Final recovery is done by hand or grease tables.
Gold concentrates are upgraded by wiffley shaking table, with refined to gold bars. The quarrying area, including safety areas, is limited to 60 Ha. The rest of the land can be developed for real estate as the premises have access to electricity, water and telephone. Conservative estimates suggest that the real estate profits could pay for the purchase of the quarry, which will remain the sole granite quarrying area within 50 Km. The gravel quarry lies within city limits of another fast-growing metropolitan region with 6 million inhabitants.
