Repeat the process with the ramp with the other box. Now that the boxes are all on the upper floor, it's time to move them to where they belong. However, since we want the GOLDEN ARTEFACT, we will do things a bit differently.

Geology of Gold Mineralization & How Gold Deposits are Formed

Though scarce, gold is concentrated by geologic processes to form commercial deposits of two principal types: lode (primary) deposits and placer (secondary) deposits. Lode deposits are the targets for the “hardrock” prospector seeking gold at the site of its deposition from mineralizing solutions.

Gold plating - Wikipedia

Gold plating is a method of depositing a thin layer of gold onto the surface of another metal, most often copper or silver (to make silver-gilt), by chemical or electrochemical plating.This article covers plating methods used in the modern electronics industry; for more traditional methods, often used for much larger objects, see gilding.

Electroless Deposition - an overview | ScienceDirect Topics

Electroless deposition of metals is based on the deposition and reduction of metallic ions (reducing agents are formaldehyde, hydrazine, hydroxylamine) (155–158) from a solution to a surface without applying an electrical potential (159). The key feature of the electroless deposition process is that gold deposition begins at the pore wall.

What is PVD Gold Sputtering? - Thin Film Deposition

Gold Sputtering coatings are a thin film deposition process where gold or a gold alloy is bombarded with high energy ions in a vacuum chamber resulting in the gold atoms or molecules being “Sputtered” into the vapor and condensing on the substrate to be coated such as jewelry, circuit boards or medical implants.

Sputter deposition - Wikipedia

Sputter coating in scanning electron microscopy is a sputter deposition process to cover a specimen with a thin layer of conducting material, typically a metal, such as a gold/palladium (Au/Pd) alloy. A conductive coating is needed to prevent charging of a specimen with an electron beam in conventional SEM mode (high vacuum, high voltage).
