Consolidated Thompson Iron Mines Limited (TSX:CLM) ("Consolidated Thompson") and
Quinto Mining Corporation (TSX VENTURE:QU) ("Quinto") are pleased to announce
that they have signed a letter of agreement whereby Consolidated Thompson will
acquire all of the outstanding common shares of Quinto in exchange for common
shares of Consolidated Thompson (the "Transaction"). As a result of the business
combination, Consolidated Thompson will acquire neighbouring iron ore deposits,
and significantly increase its mineral resources and exploration growth
potential. This acquisition will further establish Consolidated Thompson as a
significant player in the Labrador Trough iron ore camp, while positioning
itself well to participate in further consolidation in the iron ore industry.
Pursuant to the Transaction, Quinto shareholders will receive one Consolidated
Thompson common share for every five Quinto common shares held.


Upon completion of the Transaction, Quinto shareholders will hold approximately
13.6% of the issued and outstanding Consolidated Thompson common shares.


The Boards of Directors of both Consolidated Thompson and Quinto support the
proposed business combination.

Highlights of the Transaction

Upon completion of the Transaction, the combined company will have:

- An estimated measured and indicated mineral resource totaling 940 million
tonnes grading 29.33% Fe of which the measured resource totals 488.5 million
tonnes grading 29.91% Total Fe and the indicated resource totals 451.5 million
tonnes grading 28.71% Total Fe (NI 43-101 review carried out by Watts, Griffis
and McOuat Limited); 


- Potential production growth through the integration of Peppler Lake and
Lamelee deposits, located within 40 km of Consolidated Thompson's Bloom Lake
deposit, which is currently being developed by Consolidated Thompson and is
expected to be in production in Q2 2009 at 7 million tonnes of iron ore
concentrate per year with a 34-year mine life;


- Significant exploration potential at both Bloom Lake and the Lamelee and
Peppler Lake deposits (exploration programs are in progress at Bloom Lake and
Lamelee projects);


- Approximately $365 million in cash and cash equivalents;

- Proven management and board of directors with experience in financing,
developing and operating mines; and


- Significant strategic advantages in the largest iron ore camp in Canada,
located in Quebec and Labrador, which includes major industry participants such
as Rio Tinto plc and ArcelorMittal.


Upon completion of the Transaction, Consolidated Thompson will have
approximately 131.8 million common shares outstanding on a fully diluted basis,
with former Quinto shareholders holding approximately 13.6% of the fully diluted
combined company's common shares.


Richard Quesnel, President and Chief Executive Officer of Consolidated Thompson,
said, "Combining the Peppler Lake and Lamelee iron ore deposits with the
neighboring Bloom Lake deposit dramatically increases Consolidated Thompson's
potential iron ore resources on an absolute and per share basis. A 'tip of the
iceberg' acquisition of these deposits could propel Consolidated Thompson into
the heart of continued consolidation in the Labrador Trough. Some of the many
opportunities expected to be realized from this transaction include: purchasing
the resources at an attractive cost, significant scope for eventually increasing
production, and significant synergies to be expected through rail, port and
G&A."


Tyrone Docherty, President and Chief Executive Officer of Quinto, commented
"From the perspective of a Quinto shareholder, the transaction provides an
attractive immediate premium while still maintaining significant upside exposure
from our share ownership in Consolidated Thompson."


Compelling Combination

The combination will bring significant benefits to each of the companies and
their shareholders. The board of directors of both Consolidated Thompson and
Quinto support the proposed combination. 


Benefits to Quinto Shareholders: 

- Values Quinto at approximately $150 million on a fully-diluted basis
(including the Quinto common shares currently held by Consolidated Thompson) at
the exchange ratio of one common share of Consolidated Thompson for every five
Quinto common shares held. This represents a premium of 39% based on the 20-day
volume weighted average price of Quinto and Consolidated Thompson shares to
April 18, 2008, the trading day prior to the announcement, and 16% based on the
respective closing prices on April 18, 2008;


- Provides exposure to production at Bloom Lake; 

- Facilitates development of Quinto's iron ore projects, as the Peppler Lake and
Lamelee deposits are located within close proximity of Consolidated Thompson's
Bloom Lake property;


- Provides financial strength and near term cash flow for continued development
of Peppler Lake and Lamelee deposits;


- Leverages the knowledge and experience gained by management of Consolidated
Thompson in connection with the development of the Bloom Lake property including
experience with operations in the Camp and in negotiations with local
communities and governments; and


- Provides shareholders with a significant stake in the combined company.

Benefits to Consolidated Thompson Shareholders: 

- Adds high quality assets to Consolidated Thompson's long-term growth plan;

- Significantly increases estimated mineral resources and offers substantial
growth potential;


- Provides an opportunity to significantly leverage the investments being made
to develop the Bloom Lake property;


- Increases exposure to strong iron ore cycle; and

- Positions Consolidated Thompson well to participate in expected future
consolidation in the iron ore industry.

purchase warrants that entitle it to acquire 2.5 million Quinto common shares,
representing 7.7% of Quinto's fully diluted shares outstanding.

for a transaction of this nature, including the right to match competing offers
made to Quinto. The letter agreement also provides for a break fee of $4 million
