Tesoro Resources extends El Zorro gold mineralisation with more wide intercepts

Tesoro Resources gold ASX TSO El Zorro drill results Chile
Tesoro has returned further wide, high-grade gold results at its Chilean project with a phase two drilling campaign in planning stages.

Tesoro Resources (ASX: TSO) has announced further assay results from the Ternera prospect at its El Zorro gold project in Chile, with the recovery of wide high-grade intercepts continuing to extend the gold mineralisation.

Results from a further three holes drilled at the prospect, previously known as Coquetas, have returned wide gold zones and confirmed mineralisation of multiple CC faults from surface to more than 150m downhole.

One significant deep intersection returned 4.3m at 7.25 grams per tonne of gold from 146.7m, including 2.3m at 13.3g/t gold from 146.7m and 2m at 1.86g/t gold from 275m.

Other notable assays included a wide intercept grading 1.32g/t gold over 121.55m, including up to 10.69g/t gold over 4.7m; and a 14m intersection grading at 3.06g/t gold from 155m that included 1.7m at 19.72g/t gold from a depth of 162.2m.

Meanwhile, a preliminary independent review by Cube Consulting has confirmed Tesoro’s geological model that higher-grade gold mineralisation is associated with the CC structures.

Ternera (formerly Coquetas) prospect

Tesoro commenced a phase one drilling program in February to follow up on large-scale channel sampling undertaken late last year at what was named the Coquetas prospect.

Drilling has continued to return high-grade gold assay results including wide intercepts measuring up to 98.3m and earlier this month, channel sampling results expanded known mineralisation to 1.5km.

The company has recently decided to change the names of its targets Coquetas and Coquetas South to Ternera and Toro Gordo, respectively.

It said the change was made to reflect the distinct differences between each prospect’s mineralisation styles and intends to relieve potential confusion between the target names and the concession of the same name.

Phase two drilling

Tesoro’s first drilling phase has now been completed with 11 holes drilled for 2,855.3m.

Assays are still outstanding for two holes and planning is already underway for a phase two program.

Tesoro said this second phase of drilling is scheduled to begin in July. The program will focus on infill and extensional drilling at Ternera to advance the project towards a maiden resource estimate.

Geological data review

As part of Tesoro’s work programs at El Zorro, it engaged Cube Consulting to manage the company’s geological database and provide consulting services.

Cube recently conducted a geological data review of Tesoro’s work completed at El Zorro to date and evaluated the gold mineralisation exploration model proposed by the company with a particular focus on the Ternera prospect.

Following a preliminary review of Tesoro’s diamond drilling results, Cube confirmed the company’s interpretation of higher-grade mineralisation being associated with El Zorro’s CC structures.
