Arco de oro - location and traits
The Arco De Oro target is located in the SW corner of the Salvadora Property and has a history of artisanal mining on its epithermal gold-silver-copper vein systems. The target epithermal veins are well-defined.
Geochemical work conducted to date along with historical mining data - coupled with drilling conducted by San Lorenzo - suggests that the vein system extends for over 2 km in a NW/SE direction. The system remains open at depth due to limited drilling having been done to date.
Arco de oro - work to date
San Lorenzo conducted surface geological investigations based on artisanal mining visible at surface followed by detailed sampling of the surface workings and their extensions along strike followed by IP surveys and drilling. A total of 5 holes have been drilled by San Lorenzo in 3 drill programs completed in 2016, 2018 and 2022.
Results : Surface chip samples taken from old workings and outcrops along the vein systems range from 8.2 g/t Au and 15.5 g/t Ag over 0.9m to 154.5 g/t Au and 18.2 g/t Ag over 1.3m width.
Arco de oro drilling
San Lorenzo Gold has conducted 3 phases of drilling on the Arco deo Oro Target.
Drill intercepts range from 12m grading 1.74 g/t Au with 2.9 g/t Ag and 0.27% Cu (SAL-04-18) to 32m grading 1.66 g/t with 2.3 g/t Ag and 0.32% Cu.
The broad zones noted above centered on higher grade cores ranging from 4m grading 6.84 g/t Au with 6.0 g/t Ag and 0.57% Cu (SAL-04-18) as well as 6.5m grading 16.27 g/t Au with 9.9 g/t Ag and 0.39% Cu (SAL-04-22).
