International Nickel Ventures Corporation: US $2 Million Exploration Program Underway on INV’s 100%-Owned Brazilian Nickel Claims

TORONTO, ONTARIO – (CCNMatthews – May 31, 2006) – International Nickel Ventures Corporation (“INV”) (TSX:NVC) is pleased to report on the status of exploration work on its 100%-owned properties in Brazil.

INV’s 100%-owned land position now encompasses over 120,000 hectares among Brazil’s major nickel camps. The three main areas cover:

1) The vicinity of the Santa Fe/Ipora properties in Goias State;

2) Northeast towards Votorantim’s producing Niquelandia nickel laterite mine and Anglo American’s developing Barro Alto nickel laterite mine; and

3) In Para and Tocantins States near Falconbridge’s Araguaia nickel laterite discovery first announced in September, 2005.

INV is conducting exploration work through Amazonia Mineracao, a Brazilian based exploration and mining company with an exceptional team including Marco Tulio, Exploration Manager and Joao Antonio da Silva, Nickel Exploration Project Manager formerly in charge of the development drilling program at Onca Puma for Canico. The overall exploration program is supervised by INV’s consultant Roberto Pereira, based in Rio de Janeiro, who brings extensive geological and geophysical experience from BHP.

Although limited exploration work was carried out prior to INV having gone public, the full exploration program began in mid-April, 2006. Exploration is focused on aeromagnetic anomalies located in similar favourable ultramafic rocks known to host all of the major nickel laterite deposits in Brazil. To date, INV has identified 24 such targets. Follow-up is being conducted via ground magnetometer surveys, geological mapping, auger drilling and reverse circulation (RC) drilling. While total expenditures will depend on results, INV expects to spend over US$2 million this year on overall exploration on its 100%-owned claims.
