YAUTEPEC PROJECT

WKN: A2QQ1X
Vancouver, BC, Canada - Madoro Metals Corp. (“Madoro” or t he “Company”), 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 Company’s press release of April 22, 2021,
Madoro added three new mining concessions covering th e southern extension of its project based on
the Company’s 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 are a 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’ Explora tion 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 bel t hosting both Fortuna Silver’s (NYSE: F SM) 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 Madoro’s exploration model for bonanza grade
Au-Ag-polymetallic epithermal systems in Oaxaca.
