Papua New Guinea (PNG) is a culturally diverse, environmentally rich country with over five million inhabitants, the majority of whom live on the eastern half of the rugged and mountainous island of New Guinea, the rest scattered among tropical archipelagos in the Bismark and Solomon seas. PNG's natural beauty hides a legacy of poverty and dependence on natural resources, especially mining operations: there are currently six working mines in PNG, five on the main island in rural, mountainous, and unimaginably remote locations. The sixth operating mine, and the only closed mine in the country, are situated on the small islands of Lihir and Misima.
