ASX-listed aspiring Chile copper developer, Hot Chili, has been granted crucial water extraction rights for its overarching Costa Fuego porphyry copper-gold project located about 600km north of the country's capital, Santiago. The company says the maritime concession, which was granted following an exhaustive seven-year application process, represents a critical infrastructure requirement for Costa Fuego by securing sufficient water supply to support a large-scale copper-gold operation.
