 FENIX GOLD PROJECT
 
 The  Fenix Gold Project is one of the largest undeveloped gold oxide, heap  leach projects in the Americas, hosting a Measured and Indicated mineral  resource (as such term is defined in National Instrument 43-101  -Standards of Disclosure for Mineral Projects, “NI 43-101”) of 4.8  million ounces of gold which the Company believes will make a positive  contribution to the Atacama Region and Chile. The Project is an example  of modern gold mining where a full complement of technical,  environmental, and social considerations has been consulted and designed  from the outset. The Project represents a significant investment in the  gold mining business in Chile by a junior mining company of  approximately US$235M of initial and sustaining capital, generating  employment for at least 1,200 people during the construction phase and  800 people during the 17-year operations phase. The mine being  contemplated will be a run-of-mine heap leach operation; no crushing or  tailings storage facilities are required, thereby minimizing the overall  impact and footprint of the Project.
