Corporate Presentation

1. Serra Pelada
Building Brazil’s Next Gold Mine

2. 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.

11. Underground Drilling
DEFINING AND DELINEATING THE CMZ
• Exploration and definition underground
drilling commenced in Dec 2011
• Bulk sample, being extracted from
CMZ, will be processed at site
• An initial NI 43-101 resource statement
will follow which will outline the initial
resource estimate for approximately
one year, allowing the Company to
more accurately predict future earnings
• The drill spacing for this resource
statement will be as tight as possible (5
to 10 metre centres)
• As decline and underground
development advances, so will the pace
of drilling

42. Cutia Project
DRILLING COMMENCES IN 2013
September 10, 2013 42
• Initially believed that Cutia
showings were orogenic
gold type deposit
• Once drilling began, became
clear that system shares
more characteristics with an
IOCG type deposit than with
an orogenic gold type
deposit.

43. Serra Pelada
A COMPELLING INVESTMENT
• Gold & PGM grades at Serra Pelada are among the highest on record
• High grade, potential low cost emerging producer
