Ground geophysical surveys, which will underpin Desoto Resources’ maiden drill program, are progressing well at its Fenton gold project in the NT, with strong EM and IP anomalies identified.

Ground electrical geophysics is key to unlocking exploration potential at the project, where observations on historic drill cores demonstrate the correlation of elevated gold intervals with intensely sheared pyrrhotite rich zones, confirming the potential to host gold mineralisation along the Fenton Shear Zone (FSZ).

The target ore zones are predicted to have a high conductivity response to Electrical Magnetic (EM) surveys and a high resistivity/chargeability response to an Induced Polarization (IP) geophysical survey.

To date, the survey focus has been on determining if there is a geophysical response from the known mineralisation intercepted by historic drilling whilst testing for new mineralisation target zones between, and along strike from FEND14 and FEND18.

Early results have successfully identified chargeable/conductive responses along the FSZ including:

  • A strong late-time conductor in Fixed Loop EM proximal to FEND14 intercept (17m at 0.71/g/t Au); and
  • Moderate amplitude chargeability and resistivity anomaly in Pole Dipole 2D IP survey, proximal to FEND18 intercept (55m at 0.89g/t Au).

Desoto Resources (ASX:DES) has also detected additional anomalies that warrant follow-up infill lines as they may be the response of disseminated sulphide mineralisation along the structure – and observations on drill core indicates that these increased zones of sulphides can be related to gold mineralisation.

Ground geophysical survey is expected to be completed mid-July with the company’s maiden drill program to commence shortly thereafter.

The survey is now around 60% complete, and additional EM loops and IP lines will now be collected to follow-up on these anomalies detected to date.

Following completion of the remaining geophysical program all results will be reviewed and drill targeting finalised.
