The gold results keep coming for Tesoro Resources (ASX: TSO) at its El Zorro project in Chile, with the first hole drilled at Ternera East hitting gold in two zones.
According to the company, assays from this eastern prospect have returned 21.28m at 0.34 grams per tonne gold from a depth of 97.5m, including 4.5m at 1.14g/t from 105m, and 36m at 0.4g/t from 243m including 4m at 1.69g/t from 249m and 1.05m at 1.77g/t from 273m.
The gold mineralisation came from two zones of the El Zorro Tonalite (EZT), the favourable gold host rock at the project.
As a result, the drilled Ternera gold system has been expanded by about 500m to the east.
These latest assays follow other recent successes at the project. In June, Tesoro reported high-grade results from extensional and infill drilling at Ternera that extended mineralisation 150m to the east, and ‘bonanza’ gold grades were returned from continuously mineralised north-south fault zones at the prospect.
In today’s update, Tesoro managing director Zeff Reeves said this “significant development” at Ternera East highlights the potential for the Ternera gold deposit to continue to expand with additional exploration and drilling.
“This is an exceptional result for the first hole into the new Ternera East target and indicates the presence of significant gold mineralisation with the EZT in the hanging wall of the Ternera gold deposit,” he added.
Further drilling planned
Tesoro currently has six rigs in operation at the El Zorro project and to date, it has completed 190 diamond drill holes for 58,555m. Assays remain outstanding for 57 holes.
The company said a second hole drilled at the Ternera East prospect has intercept altered EZT up to 100m thick with assays pending.
Additional drilling is being planned to delineate gold resources at Ternera East.
“The Tesoro team is prioritising additional drilling at Ternera East to rapidly delineate what is emerging as a major extension to the expanding Ternera gold deposit,” Mr Reeves said.
