  • San Marco Resources Inc. announced it was awarded the Espiritu 2,712 ha SMR concession in the recent mineral concession lottery by the Mexican government. The property is less than 30 km SE from San Marco’s Chunibas and 1068 projects in the Sahuaripa district. “Espiritu SMR overlies a window of pre-mineral cretaceous volcanic and sedimentary rocks intruded by Laramide age granitoids”. Previous operator in the area, Kootenay Silver Inc. stated: “An extensive area of polymetallic vein, stockwork, breccia and gold-copper porphyry mineralization”. A porphyry copper setting and a vein and stockwork zone of precious and base metal mineralization are separated by a major fault. Selected drill hole intercepts include 48.0 m @ 0.19 g/t Au, 0.1% Cu; 220.5 m @ 0.14 g/t Au, 0.15% Cu. San Marco is preparing to do a first-pass ground validation and prospecting.

The strongest anomalies occur in folded, faulted metasedimentary rocks of Jurassic age, in close proximity to diorite and monzonite dikes. An induced polarization survey has identified low angle structures conducive of orogenic gold deposits. A 1.4 km of trenching on 16 trenches has been completed, with multiple intervals of anomalous gold, like 18.0 m @ 0.56 g/t Au, 24.9 m @ 0.32 g/t Au, 18.2 m @ 0.20 g/t Au, 10.9 m @ 0.38 g/t Au.
