Property location and description:

The Matachewan property is located in the southwest portion of Cairo Township in the Mining District of Timiskaming, Province of Ontario, NTS sheet 41P/15. The centre of the property is located on 80°37’ W and 7°55’ N at 1.5km east of the town of Matachewan, Ontario.

The property consists of thirty-five (35) Mining Titles owned by Alexandria. All the claims are in good standing (Figure 1) and verified on the web site of the Ministry of Northern Development and Mine.

The Alexandria (50%) – Carmax Option Property consists of nine (9) Mining Titles owned by Carmax Exploration Ltd.  Alexandria Minerals Corp. has entered into an option agreement to explore and earn 100% ownership in the mineral rights of the property.

The infrastructure and accessibility is excellent as it is located on the east side of Matachewan, a community with a long mining tradition, and is bisected by Highway 66.

Regional setting:

Rocks occuring on the Matachewan Property are Archean metavolcanics including ultramafic rocks, komatiitic basalt, andesite, rhyolite, dacite and massive and banded mafic to felsic tuffaceous units. The Archean metavolcanics and metasediments are intruded by granodioritic to syenitic intrusions. Diabase dykes cut the previous units as north striking swarms. The younger Proterozoic sediments of the Cobalt Group overly the above units.

Two principal types of gold mineralization have been exploited in the Matachewan Camp (Figure 2). At the former Matachewan Consolidated Mine, 3km west of the Property, early production was from a system of irregular orebodies consisting of a series of flat-dipping quartz stringers and adjacent altered, mineralized volcanics and/or tuffs. Two types of gold mineralization are described in the area. The first one consists of free gold within quartz stringers and pyrite in the same stringers and wall rocks. The second type consists of mineralized porphyric syenites with quartz filling fractures and most of the gold occurring in the pyrite. The porpyric syenite is metasomatised. The Young Davidson Mine hosts this second type of mineralization.

Economic geology:

The Matachewan Property has a favorable geological environment for gold potential. Classical Archean environments include structural deformation like fault and shear zones, like the Larder Lake – Cadillac break and related faults, pre to syntectonic intrusive rocks and low to moderate metamorphic grades. Furthermore, regional-specific geological characteristics, such as the presence of quartz poor intrusive rocks, like syenite, and the Archean volcanic-sedimentary boundary, both of which are related to gold deposits in the Matachewan to Kirkland Lake region, indicate a positive environment.

Exploration data, geologic and geophysical evidence on the Matachewan property include the location along strike with the 5.3 million ounce Young Davidson gold deposit; anomalous to high grade gold values in drill core and at the surface; strong IP anomalies; widespread alteration similar to that at Young Davidson. All those evidences support the conclusion that the property environment is favourable for gold desposit discoveries.

Significant results:

In 1995, WMC carried out a drilling program to confirm the presence of the LLCB structure. Three (3) holes were drilled and one (1) of the holes (95-3) intersected a 21 meters wide, highly altered, carbonatized and fuchsite altered section of the break with more than 5% fine pyrite. A mineralized quartz vein of 0.05 meter with pyrite, chalcopyrite and galena assayed 9.70 g/t Au. Shortly after, WMC dropped the ground.

In 2005, between October 6 and October 16, Alexandria carried out, a diamond drilling program of 754.4 meters with five (5) drill holes. The holes were located on five (5) separate IP geophysical targets and associated shear zones. A number of weak anomalous gold and silver values were obtained along some of these shear structures and weak signatures of VMS type mineralization was observed at a basalt and rhyolite contact.

In 2008, Alexandria drilling campaign intersected 2.25 g/t Au over 6m, 4.14 g/t Au over 1.5m, 5.34 g/t Au over 1.5m and 0.12 g/t Au over 10.5m east of the Webb Lake. In 2009 a grab sample pick up on an old stripped outcrop returned a gold value of 64.8 g/t Au and 5.9 g/t Au over 2.0m.

The area east of the Webb Lake and across to the northeast of Moyneur Lake carries the best indications of economic gold mineralization on the Property. This area covers a strike length of over two (2) kilometers. The host lithology is primarily variously sheared and altered metasediments intruded by numerous small syenitic bodies. Gold mineralization accompanies pyrite and chalcopyrite. Appreciable thicknesses of low-grade gold mineralization were intersected in Minorex drilling near Webb Lake (0.50 g/t Au over 9.9m). The RC drilling by Pamour in 1983, northeast of Moyneur Lake, may indicate higher grades of similar type gold mineralization (figure: 3).

The area from line 5000E eastward across the St. Paul Lake area and to the eastern Property boundary is prospective for syenite-mobilized gold mineralization in shears hosted by metavolcanics and metasediments. This East End Area features several subsidiary shears of the CLLB and, in combination with syenitic intrusives; these may form favourable loci for gold mineralization.

It is recommended to further follow up some of the anomalous gold mineralization values especially obtained in the previous drill holes MAT05-1,2,3,4, MAT08-6, and 9 along sheared sediments, volcanics and syenites and at the sediment.

– syenite sheared contacts. Further to the east, drill holes MAT05-5 and MAT-08-08 penetrated highly sheared
– mylonitized volcanics in contact with syenites and this may be a favorable gold mineralizing environment.
