Just to put this issue to rest, I did some looking into the historical records of that domain. Shortly after registration the records looked like this :

Domain Name.......... rinconlithium.com
Creation Date........ 2007-09-07
Registration Date.... 2007-09-07
Expiry Date.......... 2012-09-07
Organisation Name.... ADMIRALTY RESOURCES NL
Organisation Address. Po Box 517
Organisation Address.
Organisation Address. Melbourne
Organisation Address. 3001
Organisation Address. VIC
Organisation Address. AUSTRALIA

Name Server.......... ns0.aussieinternet.com.au
Name Server.......... ns4.aussieinternet.com.au

Both the admin and tech contacts were PT. It stayed that way until 31 may 2009, when it changed to its current form

Domain Name.......... rinconlithium.com
Creation Date........ 2007-09-07
Registration Date.... 2007-09-07
Expiry Date.......... 2012-09-07
Organisation Name.... The Sentient Group
Organisation Address. Level 24, Australia Square,
Organisation Address. 264 George Street
Organisation Address. Sydney
Organisation Address. 2000
Organisation Address. NSW
Organisation Address. AUSTRALIA

Name Server.......... ns1.mydyndns.org
Name Server.......... ns2.mydyndns.org
Name Server.......... ns3.mydyndns.org

So... doesn't look like anything suss based on the domain records. They probably just forgot to change the tech contact. At the very least, PT's @ady email is incorrect on those records.
