Madoro Metals Samples up to 12.35 g/t Gold and 1,250 g/t Silver from Newly Discovered Vein Complex at Yautepec Project
(firmenpresse) -
July 6, 2021, Vancouver, BC, Canada - Madoro Metals Corp. (Madoro or the Company) (TSXV: MDM, OTC: MSTXF, WKN: A2QQ1X) a mineral exploration company focused on Oaxaca, Mexico, is pleased to provide an update on recent exploration results from its Yautepec project. As per the Companys press release of April 22, 2021, Madoro added three new mining concessions covering the southern extension of its project based on the Companys exploration model for bonanza-grade Au-Ag polymetallic epithermal systems in Oaxaca. Madoro had since followed up by dispatching its exploration team to map and sample the southern portion of its concessions and encountered a previously unknown 7-km trend of epithermal alteration and veining along the trace of the southern project of the Yautepec project supervolcano (caldera). Specific high-potential exploration targets in this area include the Tecolote, Tortuga-Guiluna, and Southern Dike-Tepeztate vein systems as illustrated below.
Highlights of assays recently received from these areas include:
- 12.35 g/t Au and 1,250 g/t Ag from a 0.10 meter quartz vein grab sample within a 400 by 200 meter stockwork vein complex (Tecolote zone)
- 0.54 g/t Ag, 1630 ppm Cu, and 1.26 wt% Zn from a 0.10 meter vein within a 1.1 km dike and vein system; samples along this zone (Southern Dike) contain up to 0.30 g/t Au
(Summary geochemical tables for each area appended after text)
Our recent push into unexplored areas at Yautepec has yielded solid and very positive results, uncovering multiple new mineralized centers, demonstrating proof of concept for our exploration model, said David Jones, Madoro Metals Exploration Manager and Director. A general characteristic of districts with a good potential for hosting economic ore bodies is that they look consistently better with work over time; this is certainly the case at Yautepec, and we look forward to continued good news from the field.
Of particular interest is that samples from the Tecolote and Southern Dike areas are at or near the level of fossil surface hot springs (i.e., a paleosurface), meaning the entire vertical run of potential bonanza epithermal grades is conserved at depth. Metal anomalies are characteristically weak to absent in rocks from paleosurface environments, and thus any anomalies are considered highly favorable as an exploration guide.

The Madoro team has since focused its exploration efforts along the continued western projection of this mineralized trend, the results from which will be in a subsequent news release.
The Yautepec project is associated with a large supervolcano (caldera) that lies within a larger 120-kilometer volcanic belt hosting both Fortuna Silvers (NYSE: FSM) San Jose mine and Gold Resources Corp. (AMEX: GORO) Arista-Switchback mine. The areas discussed in this release were recently discovered through systematic application of Madoros exploration model for bonanza grade Au-Ag-polymetallic epithermal systems in Oaxaca.
