Assay Values up to 32.0 g/t Gold Reported from Survey/Sampling Program of the Sturgeon River Mine Waste Rock Pile

Laurion Mineral Exploration Inc. (TSX VENTURE:LME)(OTCQX:LMEFF) ("Laurion") is
pleased to announce that assays have been received from a comprehensive sampling
program completed on the 132,000 ton waste rock pile at its Sturgeon River
Property ("Sturgeon") located near Beardmore, Ontario.

The above assay results and the survey data are currently being incorporated
into an ore resource estimate by GeoVector and this information will be used to
calculate and complete a NI 43-101 compliant resource estimate by the end of
Q1-2011.


On May 13, 2010 Laurion reported that grab sampling by the Corporation's
Consultants GeoVector Management Inc ("GeoVector") of the waste rock pile
returned a range of 0.06 g/t to 10.2 g/t gold for an average grade of 2.83 g/t
gold from eight random samples. It was also reported in 1984, that a bulk sample
extracted at that time by front end loader returned an average of 2.95 g/t gold
which suggested the potential for approximately 11-12,000 ounces of gold in the
132,000 tons of the waste rock pile. This estimate of contained metal is
historical and does not conform to the current National Instrument 43-101
standards, and should not be relied upon.


On the basis of these initial encouraging results, Laurion commissioned a
comprehensive program to accurately determine the location and volume of the
waste rock pile, and to sample the waste rock pile using an excavator to dig
pits to acquire representative samples throughout the pile. 


The survey of the waste rock pile was carried out by TBT Engineering Consulting
Group ("TBTE") of Thunder Bay, using a Trimble R8 RTK GPS, with an accuracy of
approximately 1 cm. The excavation was also carried out by TBTE with hole
location determined using the Trimble GPS. Depth of the excavated pits was
determined using a tape measure to 10 cm scale accuracy. A total of 30 pits were
excavated and 46 samples were collected, with deeper pits (maximum 5.2 meters
deep) providing 2 or 3 samples at successively deeper levels. 


Sampling of the excavated material was carried out by GeoVector to acquire
samples that were representative of rock type and broken rock size. Samples were
collected in 20 litre pails and delivered to Overburden Drilling Management
("ODM") in Ottawa, Ontario. Individual sample weight was between 20.8-30.7 kg
and total sample weight tested was 1.22 tonne. ODM sorted the individual samples
into 4 fractions of greater than 63mm, 63-16mm, 16-2mm and less than 2mm. This
separation was to test the assumption that the finer fraction material would
contain more gold as the Sturgeon River Mine during its 1936-1942 production
period had hand sorted coarse quartz vein material for milling at an average
grade of 15.71 g/t gold and remaining finer high grade material and host rock
would have been designated to the waste rock pile.


The size fractions from the samples were sent by ODM to Actlabs and they were
analyzed by fire assay with AA finish. Any high grade samples over 3000 ppb gold
were further treated to fire assay with gravimetric finish to determine a final
gold grade. 


As indicated by the above table the smallest size fraction (less than 2mm) had
the highest grade material (6.20 g/t gold average), and all samples in this size
fraction had assays greater than 1.75 g/t gold. The coarsest fraction (greater
than 63 mm) had highly erratic values, but also contained the highest grade
sample (32 g/t gold). 


The Sturgeon River Mine produced 73,322 ounces of gold and 15,929 ounces of
silver processed from 145,123 tons mined primarily from the No.3 Vein during
1936 to 1942. The gold price ranged from (i)$34.87 (1936) to (i)$ 33.85 (1942).

All samples from the 2010 waste pile program were delivered by GeoVector
Management Inc. personnel to the Activation Laboratories ("Actlabs") facility in
Geraldton. Actlabs is an ISO/IEC 17025 accredited analytical laboratory.
