Gold explorer Tesoro Resources (ASX: TSO) has announced a new gold discovery at the Drone Hill prospect within its flagship El Zorro gold project in Chile.
First pass assay results from initial surface mapping and rock chip sampling programs over the Drone Hill target and to the north-west have identified a new gold trend measuring 1.5 kilometres long and up to 450 metres wide.
Surface rock chip samples include 3m grading at 101.5 grams per tonne gold, 1m at 12.75g/t, 1.2m at 12.7g/t, and 6m at 1.63g/t gold.
The Drone Hill target area is located west north-west of the Ternera, El Zorro’s main discovery.
Tesoro managing director Zeff Reeves said these latest results highlight the prospectivity of the project to host additional gold mineralisation outside of the Ternera gold resource.
“We are excited by the potential shown to the north-west of Ternera with extensive outcrops of El Zorro tonalite having been mapped over 4km from Ternera and some very strong zones of outcropping gold mineralisation,” he said.
Further mapping and sampling
The sampling program comprised 309 surface rock chip samples taken from the western margin of the Ternera gold deposit, through the Drone Hill prospect and open to the north-west.
The gold mineralisation identified and the mapped El Zorro Tonalite (EZT, the main gold host rock at El Zorro) is open to the west and north, Tesoro reported.
The company said it is currently undertaking additional mapping and sampling programs to define further drill targets.
Drone Hill discovery follows strong drilling results
In parallel to this mapping and sampling program, Tesoro is continuing to expand its Ternera gold deposit with infill and extensional drilling.
Earlier this month, the company reported drilling results from Ternera East, Drone Hill and Toro Blanco with highlights including a broad 71m intersection and gold grades of up to 7.58g/t.
The drilling is aimed at expanding the 660,000-ounce gold resource at Ternera.
