A Highly Prospective Copper Discovery The Los Azules copper discovery is emerging as a very large copper porphyry system.
The presence of a high-grade, near-surface core is important in that it may benefit the economics of the Los Azules project. If the decision is made to develop a mine at Los Azules, near-surface high-grade deposits could be produced which may help recapture capital costs sooner. Other positive economics include favorable metallurgy, simple processing technology and a large mineral resource with good potential to grow. Since the discovery of Los Azules about four years ago, Minera Andes has engaged in successive drill programs which have located new mineralization. Some 83 drill holes have produced 19,680 meters of drill core samples. Including the inferred mineral resource estimate, four years of field work are now included in an economic scoping study for Los Azules. A preliminary engineering report has also been compiled.
Since discovery, subsequent exploration at Los Azules has encountered features associated with many copper porphyry systems. Programs have been conducted to test the grade and continuity of known leachable (chalcocite) copper mineralization. In the discovery zone, strongly leached cap rock extends from the subcrop to as much as 161 meters beneath the surface followed by an enriched zone of secondary mineralization (chalcocite) over a zone of secondary and primary (chalcopyrite) copper mineralization.
