 District exploration advances at El Zorro
Key Points
  • Completion of high-resolution helicopter magnetic and radiometric survey
  • Identification of a >40km long, north-south structural corridor associated with gold anomalism
  • Multiple new intrusive bodies and structural features identified
Full Summary

Tesoro Gold Limited has completed a high-sensitivity, helicopter-borne magnetic and gamma-ray spectrometric geophysical survey over the entirety of the El Zorro Gold Project area, covering approximately 610km2. The survey data has identified several structural trends that may be associated with gold mineralisation along the El Zorro Corridor, as well as multiple intrusive occurrences that remain unexplored. In addition, three orientation programmes of systematic gridded soil sampling have been completed over the La Brea, Drone Hill and Pena Blanca Targets, successfully defining geochemical anomalies at all three targets and further enhancing their gold prospectivity. The soil geochemistry aligns well with mapped mineralised fault zones and favourable host lithologies, validating the method to effectively identify new gold targets and alteration systems associated with gold mineralisation at the El Zorro Gold Project. Tesoro plans to accelerate district-scale drilling across a number of these newly defined targets following the completion of the current Ternera infill drilling programme.

Outlook

Tesoro remains on schedule to complete the current Ternera infill drilling programme within the next six to eight weeks, after which the company expects to accelerate district-scale drilling across a number of the newly defined targets.
