The company is proposing 19 IP survey lines for about 27 line kilometres, employing conventional direct current induced-polarisation (DCIP) using a pole-dipole (P-DP) array. It believes that configuration – with a single transmitting electrode (the pole) and a pair of closely-spaced, oppositely-charged electrodes (the dipole) – will provide high-resolution resistivity and chargeability imaging to the company’s desired depth of investigation, which at this project is from surface to about 300m depth.

The survey will begin at the southern end of the Rosario East trend (RET) and continue northward on east-west lines spaced about 400m apart. The significance of the RET trend is that it hosts the old Salvadora and Royal Mines where research has unearthed many rock-chip samples carrying strong copper grades.

When the IP survey has been completed on the RET, it will progress to the Rosario Central (RCT) and Rosario West trends (RWT), before winding up in about a fortnight, with a final report expected soon afterwards.

Pan Asia has also kicked off geochemical exploration of the Rosario ground, with the company’s chief geologist David Hobby in the field.

Keen to begin its maiden reverse-circulation (RC) drilling at Rosario, management is also on the hunt for Chilean-based contractors, with a view to triggering its proposed program of about 2500m in November to test priority copper targets highlighted by the geophysics.
