Here is the excerpt from the first release about drilling, it tells you where we were drilling.
"The initial series of drill holes will test the “Zona Central IP Anomaly” in the A4, A5, A7 and A8 vein areas of Zona Central. The drill holes will test high-priority drill targets identified by Titan 24 geophysical surveys and the down-dip extensions of known gold mineralization."

If you look at the diagram below, you will see that A-6 is more on top of the anomaly and that the other A-4 to A-8 veins would roughly fall at the edges /flanks of the anomaly.
