This belt buckle is a custom-made commemorative item from Ok Tedi Mining Limited (OTML) in Papua New Guinea.
The front is engraved with “OK TEDI MINING,” referring to Ok Tedi Mining Limited (OTML), a large copper-gold mining company in Papua New Guinea’s Western Province. Established in 1981, it is now a state-owned mining company primarily engaged in open-pit copper-gold mining and processing.
“NURUMI” likely represents a specific person’s name (or the name of a mine/equipment), and “CRUSHER” means “crusher,” indicating that this belt buckle is a custom-made souvenir for employees operating crushers or related positions in the mine.
The sides are decorated with Papua New Guinean-style totems and bird reliefs, blending mining industry elements with local cultural characteristics, making it a professional commemorative accessory customized by the company for its employees.
