Temex:Silver Tailings Project Update Gowganda Silver Project
======================================================================
NEWS RELEASE NR02-2007
TORONTO, ONTARIO: Temex Resources Corp. (TSX Venture Exchange:TME,
Frankfurt:TQ1) ("Temex" or "the Company") is pleased to report results
from sampling of the tailings deposits and subsequent metallurgical
test work on the silver recoveries at the Gowganda Silver Project (the
"Project or the "Property"). The tailings deposits were generated from
the Miller Lake O'Brien Silver Mine, the largest past-producing
Cobalt-style silver mine outside of Cobalt, Ontario with historical
production of 40.7 million ounces of silver at an average grade of 22
ounces per ton silver (DMBW, 1990) between 1910 and 1972. The project
is located 3 kilometres northeast of Gowganda, Ontario and has
excellent access and infrastructure. Temex holds a 100% interest in
the Property with no underlying royalties.
The sampling and test work reported today is being conducted under the
guidance of Metals Finance, utilizing Metsolve Laboratories
("Metsolve") in Burnaby, British Columbia. Metsolve is a 50:50 joint
venture between Metals Finance Corp. and Falcon Concentrators Inc.
Temex has a consulting agreement with Metals Finance to provide
processing, engineering and silver recovery expertise on the Project.
Sampling Results
Preliminary auger samples of the tailings were taken in June 2006 in
order to verify previous results and to initiate metallurgical test
work on silver recoveries. Follow-up sampling at the same sites in
November 2006 was taken to replenish the metallurgical samples being
tested at Metsolve. The test batches of samples have demonstrated
excellent repeatability and have confirmed silver grades ranging from
140-150 grams per tonne (up to 4.4 ounces per ton) at Site #1, 60-70
grams per tonne (up to 2.1 ounces per ton) at Site #2 and 130-140 grams
per tonne (up to 4.1 ounces per ton) at Site #3. The sample sites
occur within 220 metres of each other. The results from Site #1 showed
the highest variability with sub samples ranging from 122.4 grams per
tonne to 185.8 grams per tonne. The larger variability in the higher
grade sample is attributable to the presence of coarse native silver
which creates a nugget effect. This was noted in a 2000 report by
Overburden Drilling Management which identified coarse silver from
several samples taken during a confirmation sampling program. That
report suggested that larger samples would reduce the nugget effect and
that the probability of collecting coarse silver would increase with
larger sample sizes in certain areas of the tailings.
Independent historical studies by several industry experts (including
WGM and Kilborn Engineering,) on the silver content of the tailings
established a resource of 1.827 million short tons grading 1.43 ounces
per ton silver (1.66 million tonnes grading 44.5 grams per tonne
silver). This was estimated on the basis of 545 auger holes and an
additional 152 sonic drill holes between 1980 and 1987. These mineral
resource estimates are pre-National Instrument 43-101 and a Qualified
Person has not done sufficient work to classify the historical
estimates as current mineral resources. However, based on the results
of this sampling reported today, Temex considers the estimates reliable
and relevant based on the verification of the results from historical
sampling as well as the repeatability of its own samples.
Preliminary Metallurgical Results
In addition to the sampling, Metsolve, under the guidance of Ish
Grewal, P.Eng., a Qualified Person pursuant to National Instrument
43-101, are developing a proprietary leach process specific to the
tailings material on the Temex Gowganda Silver Project. Preliminary
key results to date show silver recoveries ranging from 60% to 70% from
a bulk sample using agitated leaching at ambient pressures and
temperatures. Work is on-going to further optimize this process.
Furthermore, and of particular significance, the test work is showing
that a saleable silver product can be produced on-site with minimal
leaching of the non-commercial metals contained in the sample.
Commented Ian Campbell, President and CEO of Temex, "We are highly
encouraged by the results of the confirmation samples as well as the
preliminary test work being conducted by Metsolve; we see that an
environmentally-friendly solution to recover silver from the tailings
and rehabilitate this historic mining site can be realized. Even more
encouraging is that we see the potential to develop a saleable product
on site without the need for further upgrading." In addition, recent
diamond drill results have shown that the property contains several
high grade silver veins located beneath the tailings deposits, typical
of what was mined from the property during its history. These results
(News Release: February 1, 2007) reported intersections ranging up to
6,066 grams per tonne silver over 0.70 metres including 12,541 grams
per tonne silver over 0.30 metres (hole TGS-06-04) and 4,560 grams per
tonne silver over 0.75 metres, including 8,314 grams per tonne silver
(242.54 ounces per ton) over 0.40 metres. Additional veins not tested
but reported by the previous operator include up to 348.50 ounces per
ton silver (11,947 grams per tonne) over 1.1 metres, including 1039.10
ounces per ton silver (35,622 grams per tonne) over 0.30 metres.
Advanced Exploration Update
In conjunction with this test work, environmental and related studies
required for permitting of the project are on-going under the direction
of Knight Piesold. This work is being conducted in order to facilitate
a planned Advanced Exploration program designed to re-process up to a
maximum of 50,000 tonnes of the tailings deposits during the upcoming
field season. This bulk sample being planned will include
re-processing a particularly high grade area which contains an
estimated 28,500 tons grading 4.38 ounces per ton based on 33 auger
holes. The mineral resource estimate is pre-National Instrument 43-101
and a Qualified Person has not done sufficient work to classify the
historical estimates as current mineral resources. However Temex
believes them to be reliable and relevant based on Temex's sample
results reported today. Application for the initial closure plan and
related permits is well underway and it is anticipated that the related
public meetings will be held beginning in mid March. The Company will
also be required to submit a closure plan for the full production or
re-processing of all the tailings deposits on the Property.
Temex, focused on advancing its silver, gold, and diamond projects in
northeastern Ontario, is well funded with $3.5 million in the treasury
and has no debt. Please visit Temex at the 75th Diamond Anniversary of
the Prospectors & Developers Association of Canada at the Metro Toronto
Convention Centre March 4-5, 2007 at Booth 2635. For further

Sampling and QA/QC Procedures
Sample material was taken from the field locations by a soil auger and
collected into 5 gallon plastic pails. Sample pails were shipped to
Vancouver on commercial bonded freight carriers to selected
laboratories for metallurgical testing. The material from each of the
sample sites was dried and homogenized. A representative split of the
material from each sample site was bagged and sent for analytical work
to Assayers Canada, Vancouver, BC. according to the procedure described
below.
Silver Assay with 4-acid digestion: A 0.500 gram sub-sample is weighed
from the pulp bag for analysis. Each batch of 30 assays has three
duplicates, one natural standard and a reagent blank included. The
samples are digested with HNO3, HF, HCl and HClO4 and taken to dryness.
Samples are then dissolved in 100 ml solution with 30% HCl. This is
to prevent precipitation of lead and silver chloride. The resulting
solutions are analyzed on an atomic absorption spectrometer (AAS),
using appropriate calibration standard sets. Detection limit: 0.1
grams per tonne
The natural standard digested along with this set must be within 2
standard deviations of the known or the whole set is re-assayed. If
any of the samples assay over the concentration range of the
calibration curve, the sample is re-assayed using a smaller sample
weight. At least 10% of samples are assayed in duplicate.
Notes: 1 ppm = 1 gram per metric tonne. 1 gram per metric tonne 0.2917 troy ounces per short ton.
