Dispelling Myths on New Frontiers in Historic Mining Camps – The West Ansil Cu-Zn-Ag-Au Discovery, Rouyn-Noranda, Quebec

CIM Vancouver 2006
Gino Roger, David Rigg,
Abstract Alexis Minerals is leading exploration activities in the Southern Abitibi Belt of Quebec using an aggressive drilling program to re-evaluate the mineral potential in two significant mining districts. Targets are generated from several new advanced technologies including advanced MegaTEM II and Titan-24 geophysical methods and 3-D modeling of extensive proprietary databases using commercially available GOCAD software. Alexis conducts exploration for gold and base metals in the Val d’Or Camp and works in joint venture with Falconbridge Ltd. in the Rouyn Noranda Camp.

Rouyn-Noranda Camp
Falconbridge Limited and Alexis Minerals Corporation signed an agreement in June 2004 wherein Alexis can earn a 50% interest in all of Falconbridge’s properties in the prospective Rouyn-Noranda Base Metal and Gold Camp, Quebec. The properties cover over 75% of the central area of the Rouyn-Noranda Camp with significant interests in surrounding extensions of prospective Blake River Group stratigraphy. The exploration strategy is to apply new technologies such as MEGATEM, Gocad and Titan-24 towards the discovery of new ore deposits. Successes in the program include:

3D Gocad Model: West Ansil Discovery
In March 2005, a new zone of massive sulphides was discovered in the Central Camp area only 1.8 kilometres from the former Ansil Mine. The initial massive sulphide intersection returned 1.07% Cu over 18.75 metres and was followed by a stringer zone grading 1.80% Cu and 0.70% Zn over 7.40 metres within the Rusty Ridge Formation. Several significant results followed as drilling continued on the West Ansil deposit, including 3.35% Cu, 1.30% Zn, 1.86 g/t Au and 12.3 g/t Ag over 45.70 metres(hole WAN-05-04) and 14.34 % Cu over 6.30 metres (hole WAN-05-10). To date, three mineralized lens have been outlined within the basalt-andesite ensemble of the Rusty Ridge Formation. Mineralization occurs at a vertical depth ranging between 175m and 550m between the Lewis Exhalite and the Beecham Breccia. The new massive sulphide deposit is the first base metal discovery in the central camp since the discovery of the Ansil deposit in 1981. Success is directly derived from testing a target area generated within the Gocad common earth model of the Rouyn-Noranda central camp.
