The underground mining methods we use include room and pillar, narrow vein stoping and large-scale mechanised mining. Room and pillar mining is a style of mining where tunnels are driven in a chess board pattern with massive square pillars between them which are gradually cut away as the work proceeds. We use this for mining coal.

Gold is found in the Yanacocha Mine in microscopic bits. One hundred tons of earth need to be removed for every ounce of gold extracted. The large volumes of material are dumped onto a lined leach pad, and cyanide solution is sprayed over it. The cyanide binds with the gold and causes a solution enriched with gold to settle at the bottom.
