Marketwired Canada
DOT Resources Ltd. (TSX VENTURE:DOT) ("DOT" or the "Corporation") is pleased to
announce the results of an updated National Instrument ("NI") 43-101 compliant
mineral resource estimation ("Mineral Resource") in respect of its 100% owned
property (the "Property") in Central British Columbia, Canada.
Compared to the Mineral Estimation report dated June 22, 2009, the current
mineral resources as of November 30, 2010, at a 0.20% copper cut-off, have
increased as follows:
-- Inferred resources up 79% to 4.28 million tonnes at a copper equivalent
grade of 0.49%.
-- Indicated resources up 19% to 5.33 million tonnes at a copper equivalent
grade of 0.54%,
"We are very pleased of the success of our 2009 winter drilling program and of
the increase in resources," as stated by John J. Komarnicki, Chairman and CEO of
DOT, "This updated resource report illustrates the potential of the Property.
The recommendations for further work contained in the Aurora Report will be
considered as we formalize the details of the next exploration phase which we
anticipate will begin in the first half of 2011."
MINERAL RESOURCE REPORT
The updated independent Mineral Resource Estimate ("Mineral Resource") report
titled "Technical Report on a Diamond Drill Program and Mineral Resource
Estimate For DOT Resources Ltd's Dot Property (the "Aurora Report") was prepared
by Aurora Geosciences Limited ("Aurora") is dated November 30, 2010 and is in
accordance with NI 43-101 and the Canadian Institute of Mining ("CIM") standards
for reporting mineral resources. It is anticipated that the NI 43-101 Technical
Report will be filed on SEDAR within 45 days in accordance with NI 43-101.
The current Mineral Resource incorporates all diamond drilling results from the
Property including the assay results from 15 diamond drill core holes completed
in late 2009 and early 2010 totaling 4,355.6 m.
Current Mineral Resource categories over a range of copper cut-off grades are
summarized in Tables 1 and 2.

Notes:
(1) Mineral resources that are not mineral reserves do not have
demonstrated economic viability. See "Cautionary Note Concerning
Reserve and Resource Estimates".
(2) Rounding differences may occur from those numbers presented in the
Aurora Report following "best practice" principals.
(3) The Mineral Resource set out above for the Property is based on a 3D
geologic model and wireframe restricted block model that integrated
the exploration work on the Property up to the end of January, 2010.
The block model used a cell size of 10 m by 10 m by 10 m and Ordinary
Kriging interpolation technique was performed at various search radii
and ellipsoid orientations.
(4) A composite value of greater than 0.10% copper was used as the lower
limit for the definition of mineralization.
(5) The Indicated and Inferred mineral resource categories for the
Property set out in Tables 1 and 2 comply with the resource
definitions of the CIM and NI 43-101: Standards of Disclosure for
Mineral Projects.
(6) Copper equivalent grades are calculated using the following average
metal prices: US$3.00/lb copper, US$18.00/oz silver, US$14.00/lb
molybdenum, US$1,200/oz gold and assumes 100% recovery of all metals.
Note: the copper equivalency determined is essentially a semi-
quantitative number in that it is not based on metallurgical studies
and does not address metal recovery and a host of other production
considerations.
BASIS OF RESOURCE ESTIMATE
The current resource estimate was prepared by Mr. Ronald James Robinson, BSc.,
P.Geol., a consulting geologist from Aurora, who is an independent qualified
person within the meaning of NI 43-101. Mr. Robinson has reviewed and verified
the technical information that forms the basis of and has been used in the
preparation of the current mineral resource estimate and this news release. Mr.
Robinson reviewed all analytical data, diamond drill hole logs, QA/QC data,
density measurements, and sampling, diamond drilling and analytical techniques.
Aurora used Gemcom's Surpac geology and mine modeling design and analysis
software and an Ordinary Kriging wireframe restricted linear block model to
estimate the current mineral resources contained in five of the mineralized
zones on the Property. Classification methodology used to assign a level of
confidence to the mineral resources conforms to the CIM mineral resource
definitions referred to in NI 43-101. The analytical results and other technical
information included in the current resource estimate have been previously
announced by way of news releases over the past year and are available on
www.sedar.com.
Top cut analyses were not performed on the input data set prior to block model
estimation. Using these analyses, the assay values for the drill holes used in
the resource estimate were composited and composite values greater than 0.10%
copper were used for the definition of mineralization.
All samples contained within the mineralized wireframe were composited to a
standard length of 2.0 m for geostatistical analysis and interpolation.
Variography was performed on the assay data within the mineralized wireframe to
generate a series of semi-variograms. These variograms were incorporated into
the search ellipsoid parameters used in the interpolation process.
Based on the geological model, exploration grid, search ellipsoid ranges and
composite sizes and, the data used in the resource estimate was block modeled
with a block size of 10 m by 10 m by 10 m for the purposes of the resource
estimate.
CAUTIONARY NOTE CONCERNING RESERVE AND RESOURCE ESTIMATES
This press release and other information released by DOT uses the terms
"resources", "indicated resources" and "inferred resources". United States
investors are advised that, while such terms are recognized and required by
Canadian securities laws, the United States Securities and Exchange Commission
(the "SEC") does not recognize them. Under United States standards,
mineralization may not be classified as a "reserve" unless the determination has
been made that the mineralization could be economically and legally produced or
extracted at the time a reserve determination is made. Mineral resources that
are not mineral reserves do not have demonstrated economic viability.
United States investors are cautioned not to assume that all or any part of
Indicated resources will ever be converted into reserves. Inferred resources are
in addition to Indicated resources. Inferred resources have a great amount of
uncertainty as to their existence and as to whether they can be mined legally or
economically. It cannot be assumed that all or any part of an inferred resource
will ever be upgraded to a higher category. United States investors are
cautioned not to assume that all or any part of an inferred resource exist, or
that it can be mined economically.
NI 43-101 is a national instrument developed by the Canadian Securities
Administrators, which established standards for all public disclosure an issuer
makes of scientific and technical information concerning mineral projects.
Unless otherwise indicated, all resource estimates contained in this press
release or released by DOT in the future, have been or will be prepared in
accordance with NI 43-101 and the CIM and Petroleum Classification System. The
requirements of NI 43-101 are not the same as those of the SEC.
QUALITY CONTROL
The drilling program and sampling protocol was completed under the supervision
of Aurora Geosciences Ltd. A rigorous quality control and quality assurance
protocol was used during the drilling program, including blank, duplicate and
reference samples with each batch of assays. All drill core samples were
analyzed by atomic absorption and fire assay at Eco Tech Laboratory Ltd. in
Kamloops British Columbia. Eco Tech Laboratory Ltd. is registered for
International Standards Organization ("ISO") rating 9001-2000 and is independent
of DOT. Mr. Robinson has verified the data that forms the basis for the mineral
resource estimate and the technical information contained in this press release.
Elmer B. Stewart, MSc., P. Geol., DOT's Qualified Person as defined by NI 43-101
has reviewed the technical information contained in this release.
