@pustayo It certainly does take time my friend... it certainly does.

El Zorro Exploration History
From 1990 to 1993 Coeur d’Alene Mines Corporation undertook detailed geological mapping, geochemical sampling (419 samples), drilling of 68 holes (7,601m), excavation of exploratory adits, sampling and mapping of underground workings as part of its exploration and assessment program. However, the sampling method and recoveries on the drilling were not reported, in addition the drill core was destroyed. Therefore, the drilling results are indicative only and cannot be used under modern reporting standards. However, what this substantial amount of information does, is provide TSO with a head start in exploration of the project.

From 2014 until 2017 the current vendor of the project undertook additional mapping and compilation of the
historic datasets.

Since acquiring the project in 2017 Tesoro has undertaken: geological mapping, rock chip sampling, channel sampling (trenching) and most importantly diamond drilling of 16 holes (for 3,085m) with the following significant drill results reported:
• 84.3m @ 1.30g/t gold (inc. 4.0m @ 8.50g/t)
• 98.3m @ 1.58g/t gold (inc. 30.3m @ 3.03 g/t and 11.0m @ 4.70g/t)
• 58.8m @ 1.70g/t gold (inc 20.3m @ 4.50g/t and 6.70m @ 12.21 g/t Au)

El Zorro Geology
Within Chile, the dominant copper-gold mineralisation can be domained based on the geological setting, namely: Late Jurassic and Early Cretaceous volcanic-hosted Cu-Ag manto-type deposits, mesothermal Cu-Au-Ag veins and iron oxide copper gold (IOCG) deposits. Although the El Zorro project is located within an IOCG-type domain, the mineralisation is more typical of an intrusive related gold deposit type. The El Zorro project is located in an early Cretaceous volcanic arc containing structurally controlled batholitic intrusions. At El Zorro both the host sediments and the granodiorite have been intruded by a mineralised tonalite to diorite sill and referred to as the El Zorro Tonalite (EZT).

The mineralisation appears to be structurally controlled by NW-SE faults which crosscut the EZT. Multiple mineralisation events have been identified, including the formation of narrow high grade veins which have been exploited by artisanal mining. A larger mineralising event, resulted in gold being hosted in a dense array of dominantly vertical thin fractures (1–10 mm) representing a sheeted vein array within the EZT and hornfelsed
sediments in the contact zone. The fracturing is preferentially developed in the more brittle lithologies of the EZT, black fine-grained hornfels and quartzite.

And for the Noobtrader

The mineralisation model is reported as to be of the intrusive related gold system (IGRS) type and not thought to be a porphyry or epithermal. "This is an important differentiator for TSO in defining a new geological model for the region".

Call it speculation if you will, but old 8tey's just putting the pieces of the puzzle together... ;-)
