Serra Pelada Building Brazil’s Next Gold Mine

Forward Looking Statements

Forward-looking statements in this presentation include statements regarding the timing and nature of future exploration and development

programs that are dependent on projections that may change as drilling continues, or if unexpected ground conditions are encountered. The

Company does not currently have any mineral properties that are in production or that contain a reserve as defined by National Instrument 43-

101. In addition, areas of exploration potential are identified which will require additional drilling to determine whether or not they contain

similar mineralization to areas that have been explored in more detail. Significant additional drilling is required at Serra Pelada to fully

understand system size.

Certain information contained in this presentation, including any information relating to Colossus Minerals Inc.’s (“Colossus” or the “Company”)

future financial or operating performance may be deemed “forward-looking”. All statements in this presentation, other than statements of

historical fact, that address events or developments that Colossus expects to occur, are “forward- looking statements”. Forward-looking

statements are statements that are not historical facts and are generally, but not always, identified by the words “expects”, “does not expect”,

“plans”, “anticipates”, “does not anticipate”, “believes”, “intends”, “estimates”, “projects”, “potential”, “scheduled”, “forecast”, “budget” and

similar expressions or their negative connotations, or that events or conditions “will”, “would”, “may”, “could”, “should” or “might” occur. All such

forward-looking statements are based on the opinions and estimates of management as of the date such statements are made and are

subject to important risk factors and uncertainties, many of which are beyond the Company’s ability to control or predict. Forward-looking

statements are necessarily based on estimates and assumptions that are inherently subject to known and unknown risks, uncertainties and

other factors that may cause Colossus’ actual results, level of activity, performance or achievements to be materially different from those

expressed or implied by such forward-looking statements. Such factors include, without limitation: price levels and volatility in the spot and

forward markets for commodities; the uncertainties inherent to current and future legal challenges Colossus is or may become a party to;

controls, regulations and political or economic developments in the countries in which the Company does or may carry on business; changes

in national and local government legislation in Canada, Brazil or any other country in which Colossus currently does or may in the future carry

on business; the lack of certainty with respect to foreign legal systems, which may not be immune from the influence of political pressure,

corruption or other factors that are inconsistent with the rule of law; the speculative nature of mineral exploration and development, including

the risks of obtaining and maintaining the validity and enforceability of the necessary licenses and permits and complying with the permitting

requirements of each jurisdiction that Colossus operates; fluctuations in the international currency markets and in the rates of exchange of the

currencies of Canada, the United States and Brazil; significant capital requirements; impact of any hedging activities; taxation; additional

funding requirements; loss of key employees; changes in project parameters as plans continue to be refined; accidents; labour disputes;

defective title to mineral claims or property or contests over claims to mineral properties; and competition. In addition, there are risks and

hazards associated with the business of mineral exploration, development and mining, including environmental hazards, industrial accidents,

unusual or unexpected formations, pressures, cave-ins, flooding as well as other risks discussed under the heading “Risks Factors” included

in Colossus’ latest Annual Information Form filed at www.sedar.com. Forward-looking statements are not guarantees of future performance,

and actual results and future events could materially differ from those anticipated in such statements. All of the forward-looking statements

contained in this presentation are qualified by these cautionary statements. Colossus expressly disclaims any intention or obligation to update

or revise any forward-looking statements whether as a result of new information, events or otherwise, except in accordance with applicable

securities laws.

The technical information in this presentation has been reviewed by Graham Long, VP of Exploration of Colossus Minerals Inc. and Qualified Person for the project.

Underground Drilling DEFINING AND DELINEATING THE CMZ

• Exploration and definition underground

drilling commenced in Dec 2011

• Bulk sample currently being extracted

from CMZ

• An initial NI 43-101 resource and

reserve statement will be produced

which will outline the initial resource

and reserve estimate for approximately

one year, allowing the Company to

predict future earnings

• The drill spacing for this resource and

reserve statement will be as tight as

possible (5 to 10 metre centres)

• As decline and underground

development advances, so will the pace

of reserve drilling
