Costa Fuego Project Overview
Costa Fuego is located 17 km south of the regional township of Vallenar (population approximately 52,000), approximately 600 km north of Santiago and 160 km north of the coastal city of La Serena, in the low-altitude, coastal range of the Atacama region of Chile.
The Project comprises three mineral resources situated within a 10 km radius: Productora, Cortadera and San Antonio. The resources are located along the Pan-American Highway with an average elevation of 740 m above sea level and in close proximity to existing infrastructure of the Huasco valley and the nearby Las Losas port facilities
Over the past decade, the Company has secured permits and access to establish critical infrastructure, including surface rights for the proposed central processing facilities and associated infrastructure at Productora, electrical connection to the Maitencillo power substation, maritime concession and coastal land access rights for sea water extraction, and easements for sea water pipelines and power infrastructure.

COSTA FUEGO VIRTUAL SITE TOUR
Site tours are usually only possible for the few owing to logistical and cost constraints. Hot Chili is now able to make this possible for anyone, providing the “whole picture” of Hot Chili’s uniquely positioned senior copper development in Chile.
Investors and shareholders can navigate simply though the virtual site tour by using the toggle forward and backward function at the bottom right of the viewing screen. As the tour is interactive, the 3D view is able to be rotated in any direction as well as zoom-in and zoom-out function using your mouse or touch-screen.
Note that at each site tour location, several sub-tour locations are also available to tour and additional photos are provided of various features of interest along with simple commentary.
We hope you enjoy the tour and take the time to review all aspects of our projects from our deposits, operational sites, people and regional infrastructure to local community in which we operate.
