DOT Resources Ltd. (TSX VENTURE:DOT) ("DOT" or the "Corporation") is pleased to announce that it has received the results of the first independent Mineral Resource Estimate ("Mineral Resource") at its 4,800 acre, 100% owned DOT porphyry copper +/- molybdenum, gold, silver property (the "Property") located 17 kilometres south of the Highland Valley Mining District, in central British Columbia. The report titled "Technical Report on a Mineral Resource Estimate For DOT Resources Ltd's Dot Property (the "Aurora Report") was prepared by Aurora Geosciences Limited ("Aurora") and complies with National Instrument ("NI") 43-101 and the Canadian Institute of Mining ("CIM") standards for reporting mineral resources. The NI 43-101 Technical Report will be filed on SEDAR within 45 days. Highlights of the Aurora Report include: - at a 0.20% copper cut-off, an indicated resource of 4.47 million tonnes at a copper equivalent grade of 0.56% copper in the Southeast Zone, - at a 0.20% copper cut-off, an inferred resource of 2.39 million tonnes at a copper equivalent grade of 0.51% copper in the Southeast Zone, the Copper Zone and the East Zone, - the three zones of mineralization included in the resource estimate are open along strike and down dip, and - the copper mineralization outlined in the Northwest Zone has not been included in the resource estimate (see Historical Resource Estimate). As stated by John J. Komarnicki, Chairman and CEO of DOT, "This resource report is an important milestone for the Property as it is our first NI 43-101 compliant report and it establishes a mineral resource for 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 including diamond drilling and geophysical programs. The Property is strategically located with regard to available infrastructure and we are anxious to continue with the exploration and ultimate exploitation of the Property." The current Mineral Resource incorporates all diamond drilling results from the Property since 1996 including the drilling programs completed in 2007 and 2008. The Property drill hole database contains assay results from 27 core holes totaling 6,248 m. As a portion of the assay data used in the resource estimate was collected prior to the implementation of NI 43-101 and modern quality assurance-quality control ("QA/QC") protocols, a series of studies were conducted to validate the historic assay results, including: re-sampling of historic drill core, closest sample comparisons with 2007/2008 drill holes, and database validation with historic assay records. Aurora has reviewed the validation program conducted by DOT and has determined that the historic assays are reliable and suitable for resource estimation. Current Mineral Resource categories over a range of copper cut-off grades are summarized in Tables 1 and 2. TABLE 1 - Indicated Mineral Resource Estimate (1) The indicated resources for the Property over a range of copper cut-off grades are listed below: ---------------------------------------------------------------------------- copper copper copper silver gold molybdenum equivalent cut-off (%) tonnes (%) (g/t) (g/t) (%) (%) ---------------------------------------------------------------------------- ---------------------------------------------------------------------------- 0.1 5,352,400 0.36 2.52 0.04 0.010 0.49 ---------------------------------------------------------------------------- 0.2 4,468,500 0.42 2.91 0.04 0.010 0.56 ---------------------------------------------------------------------------- 0.3 3,539,300 0.47 3.38 0.05 0.010 0.64 ---------------------------------------------------------------------------- 0.4 2,443,300 0.57 4.22 0.05 0.010 0.76 ---------------------------------------------------------------------------- ---------------------------------------------------------------------------- TABLE 2 - Inferred Mineral Resource Estimate The inferred resources for the Property over a range of copper cut-off grades are listed below: ---------------------------------------------------------------------------- copper copper copper silver gold molybdenum equivalent cut-off (%) tonnes (%) (g/t) (g/t) (%) (%) ---------------------------------------------------------------------------- ---------------------------------------------------------------------------- 0.1 2,873,300 0.35 2.51 0.03 0.003 0.44 ---------------------------------------------------------------------------- 0.2 2,386,900 0.4 2.89 0.03 0.004 0.51 ---------------------------------------------------------------------------- 0.3 1,863,300 0.46 3.41 0.04 0.004 0.63 ---------------------------------------------------------------------------- 0.4 1,105,000 0.58 5.00 0.05 0.004 0.73 ---------------------------------------------------------------------------- ---------------------------------------------------------------------------- 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 (see Figure 1) and wireframe restricted block model that integrated the exploration work on the Property up to June, 2008. The block model used a cell size of 10 m by 10 m by 10 m and Ordinary Kriging interpolation technique was performed at different search radii and ellipsoid orientations. (4) A composite value of greater than 0.20% 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$1.50/lb copper, US$14.00/oz silver, US$13.50/lb molybdenum, US$975/oz gold and assumes 100% recovery of all metals. Commodity prices are constantly fluctuating and will be corrected by the Corporation from time to time. 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 three 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 input data for the current mineral resource estimate of the Property included all diamond drill hole results on the Southeast, Copper and East Zones of mineralization collected from the Property since 1996. 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 three years 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 0.20% 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. Ordinary Kriged method of interpolation technique was used at different search radii for the Southeast and Copper Zones and the application of Inverse Distance Squared estimation was used for the East Zone due to the limited number of drill holes completed into this zone. HISTORICAL RESOURCE ESTIMATE Prior to completion of the current mineral resource estimate, an historical estimate which is not compliant with NI 43-101 was completed on the Property. The historical estimate which included the Southeast Zone and the Northwest Zone did not conform to the CIM standards of reporting pursuant to requirements under NI 43-101. It should be noted that a "qualified person" has not done sufficient work to classify the historical estimate as a current resource or mineral reserve. DOT is not treating the historical estimate as current mineral resources or mineral reserves as defined by NI 43-101 and historical estimates should not be relied upon. The drilling completed in 2007 and 2008 did not verify the historical results of the Northwest Zone, therefore, additional drilling is required to verify the historical results. Based on the historical estimate, the Northwest Zone was estimated to contain 1.29 million metric tonnes grading 0.56% copper. This zone has a minimum strike length of 270 m, a width of 55 m and has been drilled to a depth of 200 m. The mineralization in this zone is open long strike and at depth. 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 rule 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 programs and sampling protocol was completed under the supervision of Elmer B. Stewart, MSc., P. Geol., DOT's Qualified Person as defined by NI 43-101. 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.
