DOT Resources Ltd. (TSX VENTURE:DOT) ("DOT" or the "Corporation") is pleased to
announce the results of 7 of 15 diamond drill holes ("DDH") from its recently
completed diamond drilling program on its 100% owned Dot porphyry copper
property (the "Property") located 17 kilometres south of the Highland Valley
Mining District, in central British Columbia (see Figure 1).
The main focus of the 2009 and 2010 diamond drilling program was to test the
extensions of the copper-gold-silver mineralization previously outlined in the
Southeast Zone, confirm the continuity of the copper mineralization in the
Northwest Zone and test several Induced Potential chargeability anomalies
previously outlined on the West Zone. Analytical results for the 8 DDH completed
on the West Zone are expected by the end of February, 2010.
Drilling Highlights:
- 0.71% copper, 0.92 g/t gold, and 7.24 g/t silver over 50.35 metres in the
Southeast Zone,
- Continuity of the copper-silver mineralization in the Northwest Zone established.
Northwest Zone
The drilling program on this zone was designed to test the continuity both along
strike and at depth of the copper mineralization intersected by diamond and
reverse circulation drilling programs completed prior to 2007. The weighted
average grade of the mineralized intervals in the Northwest Zone was estimated
using a 0.05% copper cut-off grade. The apparent length and weighted average
grades for the two DDH drilled on this zone are set out in Table 1.

The intervals set out in the above table are not true widths.
The two DDH completed on this zone have confirmed the down-dip continuity of the
copper mineralization intersected in the historical analytical drill holes.
In DDH DOT-09-NW-05 native copper occurs with thin quartz hematite veins and
veinlets in moderate potassic and argillic altered granodiorite.
In DDH DOT-09-NW-06, trace native copper, chalcopyrite and more abundant bornite
occur in thin quartz-hematite veinlets in granodiorite exhibiting moderate to
strong argillic and potassic alteration.
Southeast Zone
The 5 DDH completed in the Southeast Zone intersected the strike and down dip
extension of the previously reported mineralized intersection within this zone
(see Table 2). The diamond drilling has provided greater understanding of the
geometry of the mineralized zone.
DDH DOT-09-SE-09 and DDH DOT-09-SE-11 intersected significantly higher
concentration of copper-gold and silver than was previously intersected by the
diamond drilling completed on this zone. Copper mineralization occurs as
veinlets and disseminated chalcopyrite and bornite and in thin quartz veinlets
throughout the mineralized intervals in moderate argillic and potassic altered
granodiorite. The zone of copper mineralization is open along strike to the
southeast and at depth.

The intervals set out in the above table are not true widths.
The weighted average grade of the mineralized interval in DDH DOT-09-SE-11 is
influenced by two narrow intervals of higher grade copper-gold-silver
mineralization. The sample interval 99.55 to 99.82 metres ("m") assayed 2.43%
copper, 0.10 g/t gold and 15.9 g/t silver. The interval from 113.48 to 114.10 m
assayed 6.39% copper, 1.54 g/t gold and 54.0 g/t silver.
Diamond Drilling and Sampling Procedures
Diamond drilling is completed using a 76 mm diameter core barrel. The average
core recovery is estimated to be greater than 96% although recoveries of 50%
were recorded over narrow (less than5.0 m) intervals. The cores were split using
a manual splitter and one half of the core was collected for sample preparation
and analysis and the other half is retained for future reference. Sample
intervals were selected based on lithologies and intensity of alteration. The
sample intervals varied between one and two metres and sample weights ranged
from 2.0 to 4.0 kilograms respectively.
Sample preparation was completed by EcoTech Laboratories ("EcoTech") located in
Kamloops, British Columbia using the following procedure: Core samples are
prepared using a 2 stage crushing on a jaw crusher to 70% passing 10 mesh
screen. A 250 gram sub-sample of the crushed material is pulverized on a ring
mill to 95% passing minus 150 mesh screen. The sub sample is rolled and
homogenized.
After initially analyzing the samples on the ICP/MS all samples with greater
than 1,000 ppm copper are assayed using the Aqua Regia Assay method.
Gold analyses are completed on a 30 gram sample and a repeat sample is completed
for every 10 samples. The samples are fused along with proper fluxing materials
and the resulting bead is digested in Aqua Regia and analyzed by atomic
absorption. Over-range values are re-analyzed using gold assay methods.
(Detection limit 1-5 ppb AA). EcoTech has a 9001 International Standard
Organization ("ISO") rating and is independent of DOT.
