Tesoro Resources Limited (ASX:TSO) has announced that drilling at its El Zorro Gold Project has expanded the Ternera Gold System by 500m to the east, with the first drill hole at Ternera East returning multiple zones of gold mineralisation.
Results from hole ZDDH0149 include:
- 21.28m @ 0.34g/t Au from 97.50m including:
- 4.50m @ 1.14g/t Au from 105.00m;
- 36.00m @ 0.40g/t Au from 243.00m including:
- 4.00m @ 1.69g/t Au from 249.00m;
- 1.05m @ 1.77g/t Au from 272.95m;
Drilling intercepted multiple mineralised El Zorro Tonalite (EZT) bodies, which occur within the hanging wall of the main Ternera Gold Deposit.
The increased mineralised footprint has “significantly enhanced” potential for open pit mining at the project, according to the company.
Current activity at El Zorro
Tesoro reports that assays are pending from a second hole at Ternera East, which has intercepted altered EZT up to 100m thick.
A total of 190 diamond drill holes have been completed at the project, for a total of 58,555 meters, with assays pending for 57 holes.
Gold mineralisation at Ternera remains open in all directions, with six drill rigs operating on a permanent basis.
Ternera Gold System
Tesoro has drilled over 45,000m at the Ternera Gold System, which is ~1km in length running north to south, and ~550m east to west. Gold mineralisation at the system is associate with multiple, parallel elongate tonalite intrusions, with outcropping at surface to >400m in depth.
The system hosts multiple continuous mineralised zones which have returned multiple drill results of >100m @ >1.00g/t Au. Three north-trending high-grade zones between 30m to 70m in thickness sit between 2.00g/t to 4.00g/t Au.
El Zorro Gold Project
The El Zorro Gold Project covers an area in excess of 500km² in northern Chile, approximately 140km by road from the regional city Copiapo and only 15km inland from the Pan American Highway. The project is 50 minutes by road to the port of Caldera.
Tesoro’s 95% owned Chilean subsidiary holds 85% of the El Zorro Gold Project.
“This is an exceptional result for the first hole into the new Ternera East Target and indicates the presence of significant gold mineralisation”
Management comments
Tesoro Resources Managing Director Zeff Reeves said: “This result is a significant development for the El Zorro Gold Project and 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. 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.”
