Tesoro Resources (ASX: TSO) has hit gold grading up to 69.7 grams per tonne in the first hole of the Toro Gordo target within the flagship El Zorro project in Chile.
The company has now received assays from seven diamond holes at El Zorro with four from the new Toro Gordo target and a further three from Ternera.
At Toro Gordo, notable intersections were 1m at 69.7g/t from 180m, 4m at 8.04g/t from 36m, and 2m at 3.3g/t gold 151m.
All four of the first holes drilled at Toro Gordo returned positive gold assays.
Tesoro managing director Zeff Reeves said the results from Toro Gordo were “exceptional” and demonstrated “the large quantities of gold within the El Zorro mineralising system”.
“To achieve drilling success with the first holes into a new target is a testament to our technical team and the diligent work they are undertaking to execute our work programs as well as what is now becoming a proven, extensive gold system at El Zorro.”
“The Toro Gordo mineralisation appears to be a different style for El Zorro with gold being hosted within an extensive high-grade vein system,” Mr Reeves added.
Over at Ternera, where Tesoro is focused on defining the extend of the mineralised footprint, highlight results were 45m at 1.57g/t gold from 86m, including 17m at 3.62g/t gold from 90m; and 18m at 1.05g/t gold from 60m.
These latest assays were from infill holes drilled along the north-east extension of Ternera and confirm continuity of this mineralised zone.
Four rigs are operating around the clock at Ternera.
The Ternera mineralised zone has been confirmed over more than 950m of strike and is 550m wide and more than 400m deep.
Mineralisation remains open in all directions.
A maiden resource is scheduled for later this year.
In parallel, metallurgical test work, and various studies are underway to underpin scoping and pre-feasibility studies.
