The El Zorro Gold Project is Tesoro’s main focus and covers over 500km2 and is located 140km by road from the city Copiapo in Region III, northern Chile.
The project site is well supported by established infrastructure and is only 50 minutes by road from the port of Caldera and approximately 15km inland from the Pan American Highway.
Tesoro has rights to acquire up 80% of the project by completion of a feasibility study by 2022.
El Zorro Project location showing proximity to established infrastructure
The oldest rocks in the El Zorro area are Palaeozoic sediments which have been intruded by a Jurassic diorite body of the Coastal Batholith Series which has thermally metamorphosed the sediments around the contact area.
Historical mining by artisanal workers at El Zorro is limited and has largely concentrated on early stage quartz veins in and around Ternera within the El Zorro Tonalite.
Since becoming involved in the project in mid 2017 Tesoro has carried out a number of exploration programs including drilling which has reported some promising results with a number of holes reporting over 100 g/m gold intercepts.

The Ternera prospect now has proven gold mineralisation for over 750m strike, 300m depth and varies between 40-100m wide. Mineralisation remains open in all directions.

Tesoro has classified the El Zorro Gold Project as being an Intrusive Related Gold (IRG) system and has affinities to the Tintina Province in North America. Since commencing exploration Tesoro has expanded the know occurrence of gold mineralisation and host rocks outside of the Ternera Prospect and delineated multiple targets prospective for gold mineralisation.

Tesoro has an aggressive exploration and development campaign planned and is focussed on delivering a maiden resource at El Zorro.
