Tesoro Resources (ASX: TSO) has further strengthened the story at its El Zorro project in Chile by hitting a long gold intersection at its first hole into the Drone Hill prospect.
Drone Hill is about 350m from the Ternera gold deposit that so far has been the star feature of results coming out of El Zorro.
Tesoro today reported its first hole drilled at Drone Hill intersected 11.5m at 1.13 grams per tonne of gold, including a 1.57m interval returning 7.37g/t.
That mineralised zone was intersected 212.5m down hole, but the work also intercepted two higher zones: one 106m down hole returning 2m at 0.62g/t and the other at 135.95m from surface assaying 0.55m at 1.52g/t gold.
All three zones of anomalous gold mineralisation were hosted within sedimentary rocks.
Gold hit points to ‘significant’ exploration potential at new site
Tesoro said this latest result indicates “significant” exploration potential to the Drone Hill area where extensive outcropping El Zorro tonalite, the dominant gold host rock at the Chilean project, has been mapped.
The company said this result at Drone Hill confirms the potential for finding additional gold outside the Ternera deposit and further drilling is now being planned.
This follow-up drilling will target mineralisation associated with a north-south master fault.
Tesoro managing director Zeff Reeves described the result from the first hole at Drone Hill as “exceptional” and demonstrating the extensive amount of gold in the El Zorro district.
“We are excited about what the ultimate potential for the project is, which now has multiple proven mineralised targets outside of Ternera.”
“We have a solid foundation at Ternera, where resource definition drilling is ongoing, but with additional targets such as Drone Hill and Toro Gordo returning such positive early results, it lays down the foundation for continued growth at El Zorro,” he added.
Exploration in region of multiple gold, copper mines
Meanwhile, drilling across El Zorro is proceeding seven days a week, 24 hours per day.
So far, the company has sunk 125 diamond drill holes at El Zorro for 38,063m.
Assays remain outstanding for 33 holes.
The project is located 140km by road from the city of Copiapo in northern Chile.
Tesoro has been focusing on the coastal Cordillera region in Chile, host to multiple large copper and gold mines.
The company has noted that large areas of the Coastal Cordillera remain unexplored due to the unconsolidated nature of mining concession ownership, but Tesoro has been able secure rights to a “district-scale” gold project.
Tesoro owns 70% of the El Zorro gold project.
