Tesoro Resources (ASX: TSO) has announced assay results from two prospects at its El Zorro project in Chile show it is continuing to deliver “outstanding” results including one sample returning 2m at 19.98 grams per tonne gold.
The company has been carrying out channel and rock chip sampling at the Ternera and Drone Hill prospects within the El Zorro ground.
At Drone Hill, the company has identified strike extensive vein-hosted mineralisation while at Ternera, the surface gold footprint has been extended to 800m in length and is up to 300m wide.
Ternera’s assays include 8m at 5.56g/t (including 2m at 19.98g/t), 1m at 6.24g/t, 9m at 2.18g/t and 50m at 0.42g/t gold.
Drone Hill sampling returned 1.2m at 12.70g/t, 1m at 12.75g/t and 6m at 1.74g/t gold.
The El Zorro 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.
Two diamond rigs in continuous operation
The sampling has confirmed the continuation of mineralised faults from Ternera to Drone Hill, with the mineralised footprint now identified over more than 1km of strike.
Tesoro said this “significantly” increases the scale of the El Zorro surface mineralisation.
Drilling is progressing well, the company added, with 10 holes completed for 2,607m and, so far, core from three holes having been sent to the laboratory in Santiago.
Two diamond drill rigs are operating continuously at Ternera.
Tesoro managing director Zeff Reeves said El Zorro continues to produce some exciting results from the company’s surface mapping and sampling programs.
“Our team on the ground in Chile are doing a fantastic job with multiple activities under way,” he said.
Apart from the drilling, geophysical surveys have been completed and further surface work is helping delineate and expand the gold system.
“The project is continuing to deliver outstanding results,” Mr Reeves added.
Last week, Tesoro announced it had expanded its flagship El Zorro project by 360% with applications filed for 156 new prospects. These prospects host similar prospective geology to that at El Zorro.
