The Ixtaca Zone is largely covered with altered volcanic ash. However, some narrow veins with epithermal textures come to surface in a small outcrop. Preliminary soil sampling of the area returned up to 1.0 g/t gold and 110 g/t silver.
In 2010, a drill program was designed to test a small outcrop. Due to the limited surface exposure of the Ixtaca vein system, three holes were fanned out in a small area, each in a different direction. In August , Almaden reported assay results from first hole ever drilled in the Ixtaca zone: TU-10-01 intersected 302.42 metres of 1.01g/t gold and 48g/t silver and multiple high grade intervals including 1.67 metres of 60.7g/t gold and 2122g/t silver.
Following Discovery Hole TU-10-01, drilling has traced mineralization over one kilometer in a northeasterly orientation and has shown the Main Ixtaca Zone to be a broad and robust vein system intersected by multiple high grade veinlets in a variety of orientations. Drilling has also identified two additional zones: the Ixtaca North Zone and the Northeast Extension.
