Overview Top
The Sleepy property is located on the eastern end of the Cadillac Break Property package, approximately 25 km east of Orenada, and hosts a disseminated pyrite-gold zone in the Vicour Gabbro Sill. The Company began exploration drilling in 2007 and completed a NI 43-101 Compliant Resource in the Fall of 2009. This initial resource estimate outlined a near surface inferred resource of 150,400 oz. Au (1,500,000 tonnes grading 3.0 g/t Au ). Recent exploration drilling in January 2011 has expanded gold mineralization at depth. Alexandria plans to continue exploration drilling on the property with the intent of defining a sizeable gold deposit.
 

Geology Top
The Sleepy property is located north of the Cadillac Tectonic Zone (CTZ) and is underlain by the volcanic rocks of the Malartic Group. Local geology consists of intermediate to felsic agglomerates, tuffs and flows, and a sequence of intermediate spherulitic flows, intruded by dioritic to gabbroic sills. The largest of these gabbro sills, the Vicour Sill, 100-350 m in width, is the host for gold mineralization on the property.

The Sleepy Gold Zone is a disseminated gold-pyrite mineral deposit hosted in a distinctive blue quartz tonalite layer within the differentiated Vicour Sill. This tonalite layer is laterally extensive, having been intersected at various places over much of the length of the Vicour Sill, most notably at the Sigma II gold deposit located 4.5 km to the northwest within the same Vicour Sill. The Sigma II mine produced 1.8 Mt of ore grading 1.7 g/t Au from an open pit, and has a current reserve of 1.2 Mt grading 2.8 g/t Au.

Gold mineralization in the Sleepy Zone is associated with 2% to 10% pyrite as disseminated grains and veinlets, minor chalcopyrite and local sphalerite. Principal alteration mineralogy consists of albite, blue quartz grains ("eyes") and quartz veinlets, and chlorite. Assay intervals of holes drilled to-date reveal a relatively uniform distribution of gold within the Sleepy Zone: in hole SAX-11-01, completed in January 2011, for instance, the average grade of the zone was reported as 3.81 g/t over 9.0 m, where all values ranged between 2 g/t and 8 g/t Au.
 

Historical Exploration Top
Historically there have been 206 holes, totaling more than 4,000m, of drilling on the Sleepy property. This active exploration began in the late 1970's when Soquem initiated a 20-drill hole program after positive glacial tills and geophysical signatures were discovered. In 1999, Cambior completed an in-house resource estimate on Sleepy defining a total of 152,471 tonnes grading 5.1 g/t Au.

Alexandria Exploration 2007 - 2009
Since Spring 2007 Alexandria has completed 15 drill holes on the Sleepy property totaling more than 5,600m. Exploration drilling has focused on defining gold mineralization within the Vicour Sill and expanding this gold zone west along strike and at depth. In addition to significant gold intersections within the Vicour Sill, Alexandria also discovered a stringer copper zone located 1 km east of the Sleepy deposit that intersected 0.34% Cu over 35.8 m. This new bornite and chalcopyrite copper discovery is hosted in dacitic and andesitic volcanic rocks south of the Vicour sill.

In the Fall of 2009 Alexandria commissioned Geopointcom of Val d'Or, Quebec to complete a NI 43-101 Compliant Resource. Geopointcom outlined a resource of 1,557,000 tonnes grading 3.0 g/t Au totaling 150,400 ounces of gold. Gold mineralization was defined from surface to 350 metres vertical depth, with a total width of 300 metres within the Vicour Sill and remains open along strike and at depth.

Current Exploration Top
In January of 2011, a small, 3 hole 1,500m, step-out drill programme tested gold mineralization west along strike and below the current zone of mineralization. Initial results from this campaign have been very encouraging with the first of three drill holes (SAX-11-01) intersecting 3.81 g/t gold over 14.00 metres (9.00 metres true-width). Assays are still pending for the remaining two drill holes however, these positive results continue to show the growth potential of the Sleepy deposit at depth and along strike.

A follow-up drill program of 7-8 holes began in April 2011, that will test 1) the down-plunge extension of the Sleepy deposit, and 2) for gold in the Sleepy Zone intersected about 1 km east of the deposit
