Marketwired Canada
Cream Minerals Ltd. (TSX VENTURE:CMA)(OTCBB:CRMXF)(FRANKFURT:DFL) ("Cream" or
the "Company") announces the completion of the updated mineral resource estimate
at the Company's 100% owned Nuevo Milenio Silver-Gold Project ("Nuevo Milenio")
in Nayarit State, Mexico. The Company also announces that the Board of Directors
has initiated a review of Cream's strategic alternatives intended to maximize
shareholder value. A Special Committee of independent directors ("the Special
Committee") has been appointed.
The 2012 Independent Mineral Resource Estimate replaces in entirety the 2008
Inferred Mineral Resource Estimate previously disclosed by the Company and the
Company advises that the 2008 Inferred Mineral Resource Estimate can no longer
be relied upon.
Independent Mineral Resource Estimate Summary
The updated Independent Mineral Resource Estimate was prepared by Dr. McBride
P.Eng, a qualified person independent of the company under National Instrument
43-101 - Standards of Disclosure for Mineral Projects.

Net Assumptions: The Independent Mineral Resource Estimate employed a cut-off
grade of 50 g/t silver for underground resources and 20 g/t for open pit
resources. Metal prices assumed were $30.00per ounce for silver and $1,500.00
for gold. Average true widths ranged from three metres to five metres.
The distance from a data point used to classify the resources is: 0 to 25 metres
for Measured, 25-50 for Indicated, and 50 to 75 metres for Inferred Mineral
Resource categories. Using a square pattern, the influence of each data point
is, as defined above, or less, depending on the actual distance between data
points. The mineralization is considered to be in vertical shoots so that true
widths are equal to horizontal widths. All data was presented on a spreadsheet
that automatically calculated the tonnages, grades and metal content.
The Company intends to file an updated NI-43-101 technical report within 45 days
of the date of this news release.
Sensitivity Analysis
A sensitivity analysis was conducted employing a cut-off grade of 160 g/t
silver. Performed on Dos Hornos 1, Dos Hornos 2 and Veta Tomas (underground
resources) a higher grade zone averaging 3 metres to 4 metres true width
containing 803,000 tonnes grading 1.03 g/t gold and 178.70 g/t silver averaging
229.98 g/t silver equivalent was identified. The sensitivity analysis confirms
the existence of higher grade mineralization contained within the wider three
metre to five metre veins.

Cream Minerals Limited Commentary
Dr. Derek McBride P.Eng, is convinced of the exploration potential at Nuevo
Milenio. Dr. McBride P.Eng, has noted "Nuevo Milenio is a property of merit".
The 2012 updated Independent Mineral Resource Estimate has identified 2,829,000
tonnes containing 9,660,000 ounces silver equivalent which is in the Measured
and Indicated categories and 3,554,000 tonnes containing 7,270,000 ounces silver
equivalent in the Inferred category. The property contains a minimum of seven
mineralized zones; previous drilling has provided resources on four zones and
indicated significant targets on all zones. The 2011 drill program identified a
resource on Once Bocas South which had not previously been drilled. All the
mineralized zones with significant data suggest that the best mineralization
occurs within 100 metres of surface and forms hills.
The 2011 drill program was based on a geological interpretation employing all
historical exploration data up to 2008 including widely spaced drill holes.
In-fill drilling and a portion of the step out drilling generated data which
upon review did not support the original geological interpretation which formed
the basis of the 2008 Inferred Mineral Resource Estimate. As a result the
in-fill drilling did not consistently generate assays to support the previously
estimated grades and as a result the average grade decreased. A review of the
data indicates that Dos Hornos-Veta Tomas is a near surface epithermal system
with mineralization occurring within 150 metres of surface.
Based on the results of the 2011 exploration program and reviewed by Dr. McBride
the following targets have been identified as warranting further exploration:
1. Once Bocas North and Once Bocas South are potential open pit targets
that can be expanded both at depth and on strike.
2. The transition zones identified on Dos Hornos 1 and Dos Hornos 2, in
particular the Southern Transition zone are potential exploration
targets based on intercepts of blind and semi-blind veins which returned
assays in excess of 300 g/t silver and 700 g/t silver both over one
metre. These veins appear to lie parallel to Dos Hornos 2 and Veta Tomas
possibly forming a parallel zone.
3. A structure identified through surface exploration work containing
colonial trenches and colonial shafts extends 500 metres to the south
east and is on strike with Veta Tomas. Preliminary exploration work
suggests this structure may be an extension of Veta Tomas. This would
open a potential exploration zone if the structure is a faulted segment
of Veta Tomas.
4. Chacuaco and Cafetal while earlier stage exploration targets warrant
drill testing based on exploration work which includes sampling of
trenches and Spanish workings and limited drilling having identified
several high priority drill targets.
5. Drilling to the east of Veta Tomas intersected a blind structure which
based on preliminary examination may be a fault block of Dos Hornos 2.
If this initial interpretation is correct a potential exploration zone
may be opened.
6. Earlier stage but important exploration targets include the silica cap
to the west of Once Bocas North, the northern extension of Once Bocas
North which has a surface mapped strike length of over 400 metres and
the Cafetal East zone. Each has the potential to be potential future
exploration targets.

Quality Control and Data Verification
Ferdinand Holcapek, director of Cream and director-general of Cream Minerals de
Mexico, is the Company's qualified person responsible for the Company's quality

Forward-Looking Information
Statements in this news release regarding mineral resource estimates in respect
of the Nuevo Milenio project and exploration potential of the project constitute
"forward-looking statements" within the meaning of the U.S. Securities
Litigation Reform Act of 1995 and "forward-looking information" under applicable
Canadian securities legislation. Some forward-looking information may be
identified by terms such as "believes", "anticipates", "intends" or "expects".
Forward-looking information is based on a number of assumptions believed by
management and the Company's independent qualified person to be reasonable based
on information and data currently available. However, such statements are
subject to a number of risks and uncertainties. There is significant uncertainty
inherent in any mineral resource estimate. Inferred mineral resources in
particular have a great amount of uncertainty as to their existence, as well as
to their economic and legal feasibility. It cannot be assumed that all or any
part of a mineral resource will ever be upgraded to a higher category, or to
mineral reserves, or that further exploration will confirm or validate such
estimates. Under Canadian securities rules, estimates of inferred mineral
resources may not form the basis of feasibility or other economic studies.
Actual results of further exploration may differ materially from estimates
disclosed by the Company or implied by estimates of mineral resources. The
estimating of mineral resources is a subjective process and the accuracy of
mineral resource estimates is a function of the quantity and quality of
available data, the accuracy of statistical computations, and the assumptions
used and judgments made in interpreting engineering and geological information.
Mineral resource estimates are based on many things, including assumed commodity
prices, continuity of mineralization, operating costs and exchange rates.
Changes in assumptions, including as a result of data gained through further
exploration including as to continuity and grade of mineralization, unexpected
geological formations, changes in commodity prices, and other factors may result
in a significant reduction in the reported mineral resources and could have a
material adverse effect on the Company's results of operations, financial
condition and its ability to raise additional capital.
