Tiomin Explores Brazilian Opportunities, Signs Agreement
======================================================================

Toronto, Canada, July 3rd, 2007: Tiomin Resources Inc. ('Tiomin' or the
'Company') is pleased to announce that it has entered into a mineral
exploration and development agreement with Amaz�nia Minera��o Ltda.
('AMZ'), a privately owned Brazilian company.

Under the terms of the agreement, Tiomin earns a minimum 50% vested
interest in a mineral sands or base metal project procured by AMZ by
spending US$5 million on exploration and development within a four year
period. Tiomin can then earn an additional 20% by completing a final
feasibility study within a further three years. Upon completion of the
final feasibility study, AMZ has the option to either fund its share of
continuing expenses, sell its interest to Tiomin on pre-agreed terms or
dilute down to a minimum 10% equity interest, which is convertible to a
2% Net Smelter Return.

AMZ is a respected and successful privately owned Brazilian mineral
exploration and development company. It is owned and managed by well
known Brazilian professionals, and includes internationally renowned
Canadian experts as shareholders and directors. AMZ focuses on
identifying and advancing high quality mineral projects, bringing in
capable partners to jointly develop them to production. Main
partnerships include Sert�o Minera��o, a JV company with Troy Resources
of Australia, which acquired and developed the Sert�o gold project,
producing more than 240,000 ounces gold in the last 4 years. AMZ has
strategic alliances with International Nickel Ventures of Canada,
Minera��o Marina of Brazil, and now Tiomin. Consequently, in the last
3 years, AMZ has become one of the most active exploration groups in
Brazil, managing annual budgets of US$5 million to US$7 million, and
employing more than 20 geologists.

Mr. Robert Jackson, President and CEO of Tiomin commented "We are
delighted to partner with AMZ, which has an extremely experienced team
of geologists and technicians in Brazil that fits well with Tiomin.
AMZ has a portfolio of interesting mineral sand and base metal
opportunities that we will jointly evaluate. We like Brazil for its
low political risk and because it is relatively under-explored. It has
clearly defined mining laws, an experienced bureaucracy and a
supportive government. Given our strong cash position, we are actively
seeking opportunities with experienced and well-connected local
partners in countries with good geology and manageable political risk.
This deal meets those criteria exactly."
