LME Laurion Mineral Exploration Inc

Laurion Mineral Exploration Inc. (TSX VENTURE: LME)(OTCBB: LMEFF) ("Laurion") announces the drill results from the Marge Vein, Sturgeon River Property, Beardmore, Ontario.

"Drilling of the Marge vein is geared to defining a Sturgeon River style gold deposit. The Marge vein is outcropping on surface and thus is available for quick mine development. There is great potential for wider zones of mineralization as there are 10 other veins subparallel or obliquely crossing the Marge vein and, the adjacent host rock is mineralized," reported Cynthia Le Sueur-Aquin, Laurion's President and CEO.

Highlights of Marge Vein

1.  Five holes were drilled in June 2010 over a 150 m strike length of the
    Marge vein and were designed to intersect an area of the vein that had
    indications of high grade gold from historical trenching and channel
    sampling.
2.  Drill Hole LME10-01 reported a high grade gold intercept of 20.20 g/t
    over 0.36 m on Marge Vein.
3.  Drill Hole LME10-03 reported 1.30 g/t Au over 0.23 m from 24.08-24.31 m,
    contained within a 7.5 m shear zones which returned 0.18g/t Au over 7.5
    m.
4.  Drill Hole LME10-04 reported 0.65 g/t Au over 1.00 m from 22.00-23.00 m
    (Marge Vein) and a second zone of 0.63 g/t Au over 1.00 m from 43.50-
    44.50 m (Sulphide Zone).
5.  Drill Hole LME10-05 reported 3.34 g/t Au over 1.03 m from 48.47-49.50 m
    (Marge Vein). This intersection has a lower grade halo mineralization,
    averaging 1.03 g/t Au over 3.78 m. LME10-05 also contained a second zone
    of gold mineralization grading 0.49 g/t Au over 3.00 m from 22.00-25.00
    m (Shear Zone).
6.  155 m of Marge vein is exposed by trenching and has been channel
    sampled. Accumulated channel samples averaged 25 g/t gold over an
    average of 0.36 m of vein width (1984).
7.  47 m of the Marge vein was exposed by trenching in 2008 and achieved an
    average grade of 17 g/t over 0.47 m in channel sampling.
8.  Drill results from LME10-01 and channel sample results confirm the
    historical high grade for this vein.

The Marge vein is contained within a sheared diorite and hosted minor pyrite. The drill holes were designed to intersect the vein at right angles. The Marge vein contacts were normal to core axis and is believed to be true thickness. The Marge vein the drilling width ranged from 10 cm to 45 cm and the altered sheared wallrock extended for a few meters on both the footwall and hangingwall contacts of the vein.

In 2008, Laurion collected six samples of host rock adjacent to the Marge vein which ranged up to 1.06 g/t gold and averaged 0.40 g/t gold, indicating the potential for the host rock between veins to carry gold grade. This is important as there are reports of at least ten other veins subparallel or obliquely crossing the Marge vein, creating the opportunity for wider zones of mineralization. Recent sampling of the Marge vein host rock (granodiorite) by GeoVector (two samples) averaged 0.26 g/t gold, supporting the historic reports of anomalous host rock. Comprehensive sampling of the wallrock could indicate a better overall grade over a mining width.

The entire drill core from the 2010 first phase drill program was logged, split and sampled at a secure core facility in Jellicoe, Ontario. Samples were delivered by GeoVector personnel to the Activation Laboratories ("Actlabs") facility in Thunder Bay. Actlabs is an ISO/IEC 17025 accredited analytical laboratory. Analysis was by fire assay with AA finish. Analytical accuracy and precision are monitored at the laboratory by the analysis of reagent blanks, reference material and replicate samples. Quality control is further assured by the use of international and in-house standards. GeoVector routinely inserted blanks and certified standards into the sample stream in order to independently assess analytical accuracy.
