Have you even come to Chile? You should either come or read more, because even though the mining industry is huge, by no means everything IT is related to mining. There's a very healthy and continuously growing startup/entrepreneurship community, with big organizations pushing to help them along, including the government, with programs like Startup Chile. BTW, GoaP is coming to Chile next week: http://geeksonaplane.com/destinations/santiago/ (I'll be participating in some of those activities).
I spent 2 week-end there (Valparaiso and Santiago), so I'm not really informed. But all my friends who emigrated from Argentina to Chile (that's 5 people) are now working at service companies related to the mining industry.
Many of my Argentine friends in the IT field moved to Chile too. But almost everything IT is connected copper mining there (at various degrees), and I'm not sure it that interesting.
