A Poor Man& 39;s Method of Smelting Gold Sciencing
You can remove the most common metals found in gold ore copper zinc and lead using elements that bond with oxygen at lower temperatures than gold. This oxidation process will make copper oxide zinc oxide and lead oxide — all of which are less dense than pure gold and will float to the top of your crucible allowing the slag to be sloughed off.

Shrinkage stoping - QueensMineDesignWiki
Shrinkage stoping is a mining method used for steeply dipping narrower ore bodies with self supporting walls and ore. It is an overhand mining method that relies on broken ore being left in the stope to be used as the “working floor” and to support the walls.

Waste and Ore Pass Design Underground Transfer Points
Ore passes are simply vertical or inclined openings for transfer of broken ore to the haulage system. They may be raises in the ore or in the walls of the deposit or timbered openings through filled stopes and as previously stated usually terminate at the bottom in some form of loading chute. They must be steep enough to insure that the ore will run freely and usually are inclined at angles
