Drills have started turning at Mercado Minerals’ (CSE:MERC, OTCQB: MRMNF) Zamora Project in Sinaloa state, Mexico.
The Vancouver-based company has contracted HR Drilling S.A.S. de C.V. to perform the inaugural drill program which consists of 1,500 meters in approximately 12 holes.
Drilling will target the Campanillas-La Franca Vein and El Triunfo Vein segments — high-grade silver and gold veins that have never been drill tested.

“Commencing drilling at Zamora is an important milestone for Mercado. This is the first drill program ever conducted on the project. Our team has mapped and sampled high-grade silver-gold mineralization at surface along the Campanillas–La Franca and El Triunfo veins, and together with the historic high-grade underground workings, this makes Zamora an attractive area to drill,” CEO Daniel Rodriguez said in the Nov. 5 news release. He added:
“This program of approximately 12 holes will test those vein segments at depth for the first time. Our goal is to understand the structural controls on the strongest silver-gold mineralization, and what we learn will guide our follow-up drilling. HR Drilling did excellent work for us at Copalito, and we’re pleased to have them back on site at Zamora.”
The goal of the inaugural 1,500-meter diamond drill program is to test several high-priority segments along the Campanillas – La Franca Vein and El Triunfo Vein, which have been targeted based on compelling surface structural information, surface geochemical data as well as historical underground geochemical data.
Initial drilling will test vein segments that have returned high-grade results at surface such as 2.40 meters of 528 g/t silver and 0.75 g/t gold, including 1.00 meters of 828 g/t silver, at the Campanillas Vein, and 1.55 meters of 381 g/t silver and 0.85 g/t gold, including 0.60 meters of 815 g/t silver and 1.66 g/t gold, at the El Triunfo Vein.
Drilling at Campanillas will also test below underground workings where historical sampling reportedly returned 14,561 g/t silver and 15.53 g/t gold from a stockpile grab sample.
Mercado is focused on expanding known and new areas of mineralization along the Campanillas–La Franca and El Triunfo vein corridors. Continued exploration of the El Triunfo Vein returned 1.55 meters (true width or TW) of 381 g/t silver and 0.85 g/t gold, including 0.60 meters of 815 g/t silver and 1.66 g/t gold.
Continued sampling and mapping has more than doubled the strike length from 180 to over 370 meters, from which a surface chip sample returned 1.55m (TW) of 381 g/t silver and 0.85 g/t gold (413 g/t AgEq), including 0.60m of 815 g/t silver and 1.66 g/t gold (868 g/t AgEq).
Additional chip sampling along the El Triunfo Vein returned 0.60m of 128 g/t silver and 0.26 g/t gold (139 g/t AgEq).
A second historical mine working along the vein has been discovered, where a stockpile grab sample returned 674 g/t silver and 1.00 g/t gold (715 g/t AgEq).
The El Triunfo Vein consists of a grey-banded, colloform to crustiform quartz vein hosting disseminated pyrite, fine-grained dark sulfides and/or sulfosalts and likely acanthite, with iron oxide staining along fractures. The vein is north-striking and has a thickness that ranges between 0.40 to 1.55 meters.
“Our systematic exploration efforts at Zamora continue to be rewarded. Mapping and prospecting work at the El Triunfo Vein has more than doubled the total strike length of the vein to 370 metres, including discovering a second historic working,” Rodriguez stated in the Oct. 26 news release.
“The highlight result of 0.60 metres of 815 g/t silver and 1.66 g/t gold (868 g/t AgEq) continues to demonstrate the high-grade nature of the veins at Zamora. All of this confirms our belief that the Zamora Project is highly prospective for silver-gold vein mineralization and is extremely underexplored.”
