The Journey
The Southern Peru district is one the premium
locations in the world for World Class
Porphyry Cu-Mo type deposits. 3 World-Class
deposits and 2 emerging projects were visited
during the 2nd version of the SEG student
dedicated field trip of 2012.
16 students from 8 countries across the world
were benefited by SEG and field trip sponsors
to visit the Southern Peru Porphyry Cu-Mo
district.
The participants would like to sincerely
express gratitude and appreciation to all the
people who ‘behind curtains’ made this field
trip possible.

The Outcome
Student participants had the ‘hands-on’ opportunity to observe,
hence recognize, a classic Porphyry Cu-Mo type deposit.
Features such as textures, mineralization style, alteration
assemblages, ore assemblages and supergene enrichment were
widely discussed and identified.
The Outcome
Student participants had the chance to be exposed to three world
class deposits, their footprints and striking features. Also, they
were exposed to discussions with experienced professionals and
academics who hugely contributed to the understanding of the
processes involved in the formation of such systems.
The Outcome
Student participants had the opportunity of visiting two emerging projects
and learning about the early stages of exploration and consequent
geologic/economic factors related to the development of such projects.
Student participants had the chance to interact with colleagues from other
institutions across the world, to share ideas and perspectives. For sure,
some of the people who just met in this trip will work together helping to
discover or develop a new world class porphyry type deposit in the future.
The Outcome
Thank you SEG and sponsors for making this trip happen!
