Thio is widely regarded as the cradle of nickel mining in New Caledonia, marking the very beginning of the industry that now defines the territory's economy. Established around 1880, these mines were the primary operations of the SLN (Société Le Nickel) company, which has maintained a continuous presence here for over a century. The mining sites are located high in the mountains surrounding the town, utilizing spectacular open-cast methods that have reshaped the peaks into distinct orange-red terraces. This long-standing industrial activity has deeply influenced the social fabric of Thio, creating a town with a strong mining identity and a rich multicultural history tied to labor migrations. Visitors to the area can witness the sheer scale of the excavation and the complex logistics involved in transporting the nickel ore from the high plateaus down to the shipping ports on the coast.
