Tesoro Resources Limited (ASX:TSO, OTCQB:TSORF ) has delineate high potential gold targets at the company’s El Zorro Gold Project in Chile.
Tesoro has identified widespread surface gold anomalism from first pass mapping and channel sampling programmes indicating the potential of the EL Zorro Gold Project to host additional gold mineralisation.
Gold mineralisation at El Zorro is closely associated with intrusive rocks that occur as dyke swarms (El Zorro Tonalite or EZT), such as the mineralisation at the Ternera Gold Deposit.
Recent first pass mapping and sampling programs have identified extensive dyke swarms of EZT to the north and west of Ternera, which are coincident with widespread elevated gold levels.
These areas are strike extensive and have the same characteristics commonly associated with gold mineralisation, including intense quartz veining, sheeted veining and alteration.
The EZT dyke swarm that hosts Ternera, outcrops at surface over approximately 1.4km of strike.
The largest new dyke swarm mapped to date, outcrops over a strike length of 3.6km with anomalous gold results returned along its entire length.
“Having just spent the week at El Zorro walking the ground with the team, I am excited about the sheer scale of the mineralising system at El Zorro and the substantial targets being delineated,” Managing Director, Zeff Reeves, said.
“It is astounding the amount of gold contained within the large scale El Zorro mineralising system, demonstrating the emergence of EL Zorro as a major gold district. Our team has successfully delineated multiple, large scale, prospective zones of the host EZT which have all the hallmarks of hosting significant gold mineralisation.
“These new targets are significantly more extensive than the footprint of the Ternera Gold Deposit. We are excited about the growing prospectivity of the district and are looking forward to drilling these areas in the coming months.”
Large Scale Gold System
Tesoro has recently carried out mapping and sampling programs over an approximate 7km by 6km area at the El Zorro Gold Project, with 1,795 samples having been collected to date.
The aim of the programme is to delineate occurrences of the main gold host rock at EL Zorro, the EZT and define additional drill targets.
To date, the work has identified large scale outcropping zones of EZT dykes, typically occurring in swarms that strike approximately north-northeast.
The most extensive of these areas extends from Drone Hill in the south to over 3.6km north and are up to 750m wide with over 12 separate EZT dykes occurring within the zone.
These areas are analogous to the Ternera Gold Deposit where gold mineralisation is primarily hosted within 6 EZT dykes along approximately 1.4km of strike and 750m wide.
The dyke swarms occur within discrete north-northeast trending corridors where multiple dykes occur and are spaced from between 10m to over 100m apart.
Low level gold anomalism is widespread along the dyke swarms with locally higher grades >1.00g/t Au associated with areas where northwest trending faults crosscut the EZT dykes.
Next Steps
Multiple high priority areas have been identified from the first pass programs and detailed channel sampling programs have commenced.
Drilling targets are expected to be defined from the detailed sampling programs in the next six to eight weeks with drilling to follow shortly thereafter.
The company is awaiting final results from the recently completed Ternera Gold Deposit drilling campaign and will announce results as soon as they come to hand.
It is expected that an updated Mineral Resource Estimate will be completed within two to three weeks following receipt of final drilling results.
