Channel sampling at Tesoro Resources’ (ASX: TSO) El Zorro project in Chile has confirmed the presence of surface gold mineralisation across 750m of strike at the Coquetas prospect – boosting the company’s confidence a large-scale deposit may be present.
The channel sampling program was carried out last year to give Tesoro a better understanding of the gold mineralisation’s distribution.
More than 1,050 samples were taken from 77 channels and produced a peak grade of 30.3 grams per tonne gold within a 1m interval.
Other notable results were 11m at 6.03g/t gold, including 3m at 20.95g/t gold; 123m at 0.37g/t gold, including 18m at 1.71g/t gold; and 19m at 1.01g/t gold.
Tesoro managing director Zeff Reeves said the results “further enhance” El Zorro’s potential to host a “significant” gold deposit.
“With the benefit of having excellent exposures of fresh rock, the Tesoro team has been able to collect detailed channel samples from across the Coquetas prospect, which have returned some excellent results.”
“The results further support the company’s geological model, with several of the already identified mineralised zones being significantly increased in size and additional previously unknown areas of gold mineralisation having been identified.”
Mr Reeves added the company had only drilled about 350m of the identified mineralisation which extends across 785m – providing “considerable scope” to boost the scale of the project.
Advancing El Zorro
A 10-hole drilling program at El Zorro is almost complete with nine holes for 2,232m now drilled.
Assays from this campaign are “imminent” and Tesoro will collate all the data it has at hand to firm up a follow up program.
These will build on previous drill results which were 98.3m at 1.58g/t gold, including 30.3m at 3.03g/t gold; 84.3m at 1.3g/t gold, including 4m at 8.5g.t gold; and 58.8m at 1.7g/t gold, including 20.3m at 4.5g/t gold.
