Utah-based Gold Standard (GSTD-Q) has discovered a mile-long gold-bearing structure in the Cachimbo gold district of Mato Grosso state in southwestern Brazil.
Company geologists located the structure on the Domingos gold prospect earlier in the year. Mapping and sampling confirmed the presence of high-grade values along a length of 1,100 ft.
Highlights from channel sampling include: 7.2 ft. grading 0.63 oz. gold per ton; 5.4 ft. of 0.16 oz.; and 20 ft. of 0.06 oz.
The structure is a silicified, brecciated shear zone ranging up to 50 ft.
wide. Alteration extends outward into the wallrock.
The company has a geophysical program of induced-polarization, magnetic and radiometric surveys. Trenching along the rest of the mile-long structure is ongoing.
Gold Standard is negotiating for permits to drill at Domingos, as well as at a second project area, Silvio, which is 40 miles away.
At the latter, where intrusive dykes and sills intrude altered granitic rocks, channel sampling has returned 0.07 oz. gold over 10 ft. and 0.03 oz.
over 30 ft., among other values.
