Looking way back at NR's (Feb 24, 2011) I read over this again (I did all the bolding & underlining):

Zona Central IP Anomaly

The chargeability anomaly below Zona Central measures >16 milliradians (pink). The anomaly is bowl-shaped and is approximately 1,800 metres by 1,700 metres and is 1,300 metres thick. There are northwest-southeast lineation’s (faults or structures) associated with this anomaly which are coincident with the known mineralized structural trends on the Tesoro property. Within the large IP anomaly there is an area of higher chargeability at >18.5 milliradians (red), which is oriented in a north-south trend. The centre of the southern end of the >18.5 milliradians chargeability anomaly is 600 metres below the surface.

The anomaly is located at the centre of a number of cross cutting structures and may be the source of the near-surface gold mineralization found in the Zona Canchete, Zona Este and Zona Central.

So, looking back @ the info on Hole #4, I'd sure be interested what they tested (assayed) below the last interval of 330.69 - 331.12 (where they got 9.4g/T over 0.43M) No info past that point, or was it less than the 1g/T cutoff? They drilled that hole 576.1M.

Hole #4 looks to be between L4250N & L4500N and to the east of the main corridor. The description from the NR from above would put a hole more around Line L4250N and right in the middle of the main corridor (IMO) Very close to where the Quantec recommended High Priority Hole # 19 was into T11

I've posted this before, but once again here's the general remarks on T11:

General remarks: A subvertical resistivity low and gradient zone is observed nearsurface on the western side of the anomaly where zone Z3 is documented. On L4250N, and L4500N the western part of anomaly is located over the south extent of mineralization (documented as““Zona Central””). At depth >500m the DC and MT resistivity show a sub horizontal resistivity low response with moderate increase of chargeability suggesting potential fo deep mineralization.
