TORONTO - May 4, 2011 - Laurion Mineral Exploration Inc. (TSX.V: LME; OTCQX: LMEFF) ("Laurion") advised that the Technical Report supporting the recently released initial Mineral Resource Estimate completed on its Bell Mountain Project locatedin Churchill County, Nevada (Press Release April 6, 2011), has been filed with SEDAR.

The report details an initial Measured and Indicated Mineral Resource estimate at Bell Mountain's Varga, Spurr and Sphinx Zones of 9,761,000 tonnes at an average grade of 0.526 g/t gold and 17.63 g/t silver hosting 165,018 ounces gold and 5,533,907 ounces silver and and initial Inferred Mineral Resource estimate of 2,046,000 tonnes of material at an average grade of 0.449 g/t gold and 13.26 g/t silver hosting 29,550 ounces gold and 872,411 ounces silver. This Mineral Resource Estimate assumed a gold price of $1,149.89 per ounce and a silver price of $20.92 per ounce. Preliminary estimates for operating costs were $11.43 per ton (mining, processing and G&A) and for recoveries were 80% for gold and 51% for silver.

The NI 43-101 Mineral Resource estimate was completed by Telesto Nevada Inc. ("Telesto"). It incorporates data obtained from 54,692 feet (16,671 meters) of 244 reverse circulation ("RC") drill holes completed on the Varga, Spurr and Sphinx zones.

Highlights of the Bell Mountain Property:

The estimated equivalent ounces of gold contained in the Measured and Indicated Mineral Resource is 265,635 ounces, and estimated Inferred Mineral Resource is 45,412 ounces. The resource estimate is comprised of mineralization found on the Varga, Spurr and Sphinx zones.
The mineralized zones remain open to depth and laterally.
The gold-silver mineralized structurally controlled Spurr-Varga fault can be traced for more than 1.8 kilometers (6,000 feet) on surface. On the fault, approximately 1.5 kilometers on strike to the east of the Varga zone, a further mineralized zone, the East Ridge CC zone, has excellent potential for resource addition. The zone had a total of 481 meters in 13 RC drill holes spaced over a strike length of approximately 300 meters, completed in 2003 by NDT ventures, which confirmed mineralization. The Mike Zone, located between the Varga the East Ridge CC Zone, displays similar widths and characteristics, and appears open to adding to the Bell Mountain Resources by further drill programs.
The Sphinx Vein system can be traced for more than 900 metres along strike by prospect pits, vein quartz float and trenching and is available to resource expansion in further drill programs.
A Preliminary Feasibility study contemplating a conventional open pit heap leach configuration and assessment for potential production is in progress.
Environmental permitting requirements to include development of baseline needs and mine plan of operations is in progress.

Metric	Tonnage ('000 Tonnes)	Average Gold Grade (g/Tonne)	Gold (grams)	Gold (ozs)	Average Silver Grade (g/Tonne)	Silver (grams)	Silver (ozs)	Total Equivalent Ounces Of Gold

Notes:

Rounding of tons as required by Form 43-101F1 reporting guidelines (Item 19) results in apparent differences between tons, grade and contained ounces in the mineral resource.
Mineral Resources are estimated at a pit discard cutoff Grade at 0.192 g/t AuEq
The assumed parameters used for Bell Mountain used establishing a cut-off grade is identified as follows:
- Gold Price - $1,149.89/oz (US) - 60% 3-year previous average/40% 2-year forward (Dec. 31, 2010)
- Silver Price - $20.92/oz US - 60% 3-year previous average/40% 2-year forward (Dec. 31, 2010)
- Recovery - Gold 80%, Silver 51%
- Total Operating Costs - $11.43/ton (mining, processing and G&A)
- Gold Equivalent Ratio - 55 to 1

Parameters used to estimate the in-situ resource are based on information supplied by Bell Mountain Group. Assumptions were made for items like strip ratio, mining costs, processing costs and recovery percentages. These assumptions were based on published and previously calculated rates for other mining operations having similar parameters, and on testwork performed on Bell Mountain samples. The operation parameters assume open pit mining and cyanide heap leaching. A conceptual open pit mining method was used for the purpose of delineating the mineralization with a reasonable prospect of economic extraction. Tonnage estimates were based on a 2.6 grams/cubic centimeter density factor. Inverse distance square method was used to interpolate grade in the resource model (geostatistical methods of calculating resources) using the database based on the RC and core drilling.
