Alexis Updates Lac Herbin Mine Resource

TORONTO, ONTARIO--(Marketwire - March 22, 2011) - ALEXIS MINERALS CORPORATION (TSX:AMC)(OTCQX:AXSMF) ("Alexis" or the "Company") announces the completion of its annual review of mineral resources and mineral reserves at its Lac Herbin Mine, Val d'Or, Quebec. The review incorporates new information obtained from on-going at the deposit. The following table summarizes the Mineral Resources as of December 31st, 2010.

Mineral Resources at Lac Herbin Mine, December 31 2010:
December 2010 Tonnes g Au/t oz. Au
Measured 67,000 9.2 19,900
Indicated 117,600 7.6 28,800
Measured and Indicated 184,600 8.2 48,700
Inferred 283,500 7.4 67,300

The 2010 mineral resource estimation was calculated using a minimum width of 1.5 meters (m) and a cut-off grade of 5.0 grams gold per tonne (g Au/t). Resources locally contain resource blocks grading 3.1 g/t to 4.9 g/t where lower grade material is included to generate acceptable mining blocks. Mineral Resource blocks were extended to mid-distance between holes on longitudinal sections and for a maximum of 20 metres where blocks are unconstrained. The review process also resulted in an updated estimation of Mineral Reserves, as summarized in the following table.

Mineral Reserves at Lac Herbin Mine, December 31 2010:
December 2010 Tonnes g Au/t oz. Au
Proven 43,000 7.45 10,300
Probable 96,000 6.45 19,900
Proven and probable 138,000 6.81 30,200

Mineral Reserves were estimated using a gold price of US$1,350 per ounce and a US$/C$ exchange rate of 1:1. A mill recovery of 92 % and royalties' of 4.5 % were considered in the calculations. A minimum cut-off grade of 5.6 g Au/t was applied. The mineral reserve estimations were based on 2D polygons. Different stope dilution factors have been applied based on mining experience and mining method used, resulting in an average dilution of 28%. Extraction was estimated at 82%. Higher operating costs were applied due to the mining of several small ore lenses. The lower production rate results in a higher cut-off grade compared to 2009, where a cut-off grade of 5.2 g Au/t was employed.

Francois Perron, Alexis President and CEO, comments: "The review of the mineral resource has underscored the need to continue exploration around our operations and we are aggressively pursuing new discovery. As we go through this challenging period at Lac Herbin our focus remains on our operations and to extend the mine life by following up nearby targets and infill drilling around the inferred resources of the mine. The Lac Herbin mine has completed its second full year of operation and our understanding of the complexities of the deposit has improved tremendously. As we transition into narrower parts of the system our team is adapting to these new operating constraints. We are reviewing our operating plan at the mine to take into account this resource update. Alexis does not intend to provide production guidance for 2011 until a full review of our operating plan has been completed."

Mineral Resources at Lac Herbin, December 31 2009:
December 2009 Tonnes g Au/t oz. Au
Measured 185,700 8.4 50,300
Indicated 572,800 6.7 123,500
Measured and Indicated 758,500 7.1 173,800
Inferred 537,200 6.0 103,500

The 2009 Mineral Resource was estimated using a minimum width of 1.5m and a cut-off grade of 2.5 g Au/t for Measured and Indicated Resources and 1.8 g Au/t for Inferred Resources. 

The significant reduction in Mineral Resources and Mineral Reserves is attributable to many factors, which include:

  • the mining of 133,000 tonnes at an average grade of 5.04g Au/t for 21,600 ounces of gold in 2010;
  • the use of higher cut-off grades (5.0 g Au/t versus 2.5 g Au/t in 2009);
  • reduced limits for the area of influence of each drill hole. These are now supported from mining experience gained in several zones outside of the principal S1 and S3 ore zones in 2010;
  • for drill intercepts where ore widths are greater than average composite widths for the zone, widths have been reduced to average ore widths; and,
  • all pillars in mining areas have been removed from Mineral Resources and Mineral Reserves and are considered non-recoverable in light of ground conditions encountered in 2010 [See News Releases: January 25, 2011].

The Mineral Resources and Mineral Reserve estimates contained in this press release were completed by the Lac Herbin Mine technical staff under the supervision of Austin Hitchins, P.Geo and Patrick Sevigny, Ing., "Qualified Persons" as defined under NI 43-101 guidelines. A NI 43-101 qualifying report will be filed in due course.
