TORONTO -- March 21, 2011 - Laurion Mineral Exploration Inc. (TSX.V: LME; OTCQX: LMEFF) ("Laurion") is pleased to announce assay results from drill holes LME10-09W and LME10-10, the fourth and fifth drill holes that complete the first phase of the Company's deep drilling program on the Sturgeon River Mine area. Both holes reported visible gold in the No. 3 vein. LME10-09W intersected the No. 3 Vein approximately 20 meters above and 15 meters north of the intersection in LME10-09, and it intersected 15.30 g/t gold over 0.55 metres. Hole LME10-10 intersected 3.02 g/t gold over 0.51 metres in the No. 3 Vein. There were multiple other zones of mineralization encountered in the hole with 1g/t to 9 g/t gold over narrow widths tabled below. Drill hole LME10-09W was designed to intersect the No. 3 Vein under the shaft location and is a wedge from drill hole LME10-09 which intersected 6.00 g/t gold over 1.73 metres in the targeted No. 3 Vein, in which visible gold was reported, including 14.30 g/t gold over 0.69 metres in the quartz portion of this zone. Hole LME10-10 was targeted to intersect the No. 3 Vein approximately 100 meters further north along the strike of the vein.

All significant gold intersections for LME10-09W are tabulated below.

All significant gold intersections for LME 10-10 are tabulated below.

Based on the azimuth and dip of the drill holes and the projected strike and dip of the veins from the underground workings it is estimated that the true width of the vein intersections is 70-85% of the drill hole intervals.

The Sturgeon River Mine historically reported production of 73,322 ounces of gold and 15,929 ounces of silver from 145,123 tons taken primarily from No. 3 Vein during 1936 to 1942, but also from the No. 10 Vein and the M Vein that were encountered at the lower depths of the mine in the later years of mine life.

The shaft was sunk to a depth of 2,100 ft. (640 m) with development to the 1,750 ft. level (530 m). Mining occurred mostly above the 1425 ft. level. These first phase drill holes were designed to intersect the No. 3 Vein at or below the level of the bottom of the shaft, and to intersect other known sub-parallel gold bearing structures.

The drill intersections received to date provide support for a down plunge extension of the No.3 mineralized shoot and indicate that additional mineralized zones on other veins and shear horizons are located close to the previous underground workings. Laurion's program is considered a first phase of delineating that mineralization for possible 43-101 resource estimation.

All sampling from the 2010 programs were delivered by GeoVector Management Inc. personnel to the Activation Laboratories ("Actlabs") facility in Thunder Bay and/or Geraldton. Actlabs is an ISO/IEC 17025 accredited analytical laboratory. Analysis for gold was by fire assay with AA finish, followed by fire assay with gravimetric finish for samples over 3 g/t Au. Samples were also treated with a multi-acid ICP process, and base metal values over detection limit were treated to ore grade base metal assays. 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 also routinely inserted blanks and certified standards into the sample stream in order to independently assess analytical accuracy. All certified standard assays were within acceptable limits.
