Notice the Teck anomaly defined a strong induced polarization measuring 500x500 meters. AAX's is the same but measures at least 500m x 1000m and is still open to the north and south. Both hit sulphide mineralisation and both hit at similar depth of just over 200m. So AAX might have just hit a grand slam homerun at the bottom of the 9th to win the World Series with this.
Keep in mind VMS deposits are often found in clusters and Teck's was the only one in this area until maybe now.
BACKGROUND
The San Nicolas Project is located 65 kilometers north of the city of Zacatecas, Mexico. The Project is a 55/45% joint venture between Teck Corporation and Western Copper Holdings Limited. The partners commenced exploration in mid-1996 within an area typified by gently rolling topography at an altitude of 2100 meters. Initial work focused on previously known copper mineralisation at the El Salvador prospect. Expansion of exploration activities identified the San Nicolas area as prospective based on limited exposures of favorable altered volcanics.
An initial drill target was identified by a follow-up geophysical survey that defined a strong induced polarization (IP) chargeability anomaly measuring 500X500meters. The first hole into the anomaly was drilled in November 1997 intersected 175 meters of massive sulphide mineralisation starting at a depth of 205meters below the surface. To date in excess of 50 drill holes have intersected the massive sulphide mineralisation. The San Nicolas “VMS” deposit contains a zinc rich zone at the top and a copper rich zone at the base. The zinc zone contains 34 million tonnes of 4.28% Zn and 0.76% Cu; while the Cu zone has 38 million tonnes grading 1.89%Cu. A preliminary minable open pit reserve of 72 million tonnes grading 1.35-%Cu, 2.27%Zn, 0.53g/tAu and 30g/tAg has been defined.
