Chile Iron Oxide - Copper - Gold Belt
IOCG Belt of Chile
2
Chilean Metals (CMX) is a 100% owned
subsidiary of International PBX Ventures.
100% owned large land holdings in the
prolific Iron Oxide - Copper - Gold (IOCG)
Belt of Chile
IOCG belt hosts numerous copper-gold
deposits including Mantos Blancos, Manto
Verde and Candelaria.
The tremendous size, relatively simplemetallurgy and relatively high grade of IOCG
deposits can produce extremely profitable
mines.
CMX projects host drill ready large copper-gold porphyries
CMX plans to drill a large IOCG Porphyry
target on Tierra de Oro in the 2012 season

Chanchero Target: Airborne Magnetics
Magnetite content (Iron) of IOCG systems generate a strong magnetic response. Airborne magnetics shows a strong magnetic response
(IOCG) adjacent to the previously define porphyry system. IOCGs are clearly distinct in character and origin from magmatichydrothermal systems (e.g., porphyries).

IOCGs & PorphyriesAn Important Pair
IOCG & Porphyry Conceptual model (Barton and Johnson, 2000) that contrasts igneous-related mineral deposits dominated by: (1) magmatichydrothermal fluids (on right, = porphyry type) with (2) those dominated by non-magmatic (external) brines (on left, = IOCG type). In many IOCG
systems the predominant fluid source is a non-magmatic brine with Fe & base metals removed. Cu(-Au)-rich IOCG deposits will principally be afunction of the availability of sulfur from an additional external source ie. nearby porphyry system.

The Chanchero porphyry target is shown to be a strong multi coincident alteration,geochem & geophysical target. The Chanchero target area appears to containboth a sulphide rich porphyry (IP) with an adjacent large IOCG type intrusive body.

The Sierra Pintada property
covers a 15 kilometer strike
length of the north-south-
trending Atacama Fault
System that is known to
host many of the major
deposits in the Candelaria
IOCG belt.
The property is readilyaccessible from the town of
Vallenar 30 km to the east
and is nearby to rail, roads,
power, water and shipping
port.

Sierra Pintada ZTEM Survey
Artisianal Workings
ZTEM Airborne deep penetration survey identifies
Atacama fault system on Sierra Pintada.
Two primary copper and gold-bearing mineralised
structures,Via and Gloria, each at least 15
kilometres in length and 50 to 200 metres in width.
Wherever these structures emerge from beneath
overburden they are the centers of numerous
prospect pits, adits and shafts to depth of 50 metres
on high grade Cu-Au (Ag,+/-Co) and Au-Cu (Ag)
fissure veins from 1-5 metres in width.
