MADORO METALS RECEIVES POSITIVE RESULTS FROM ITS AGE-
DATING ROCK ANALYSIS IN OAXACA, MEXICO
Results to be presented at the upcoming October 5-7, 2021 Discoveries Mining Conference in
Hermosillo, Mexico
FOR RELEASE: SEPTEMBER 29, 2021 TSXV: MDM

Vancouver, BC, Canada - Madoro Metals Corp. (“Madoro” or the “ Company”), a mineral
exploration company focused on Mexico, is pleased to announce results from a limited program of
uranium-lead (“U-Pb”) age dating on selected caldera-system (supervolcano) rocks from the region of its
active exploration programs in the state of Oaxaca. The study was undertaken to better quantify the
relative ages of rocks associated with gold, silver, and base metal mineralization at the Company’s
projects and compare these to the ages of similar rocks from the areas of nearby producing mines (e.g.:
Gold Resource Corporation’s Arista -Switchback and Alta Gracia mines), which lie approximately 30
kilometers along trend from the Company’s property. It was previou sly speculated, based on our
understanding of local and regional geologic controls, that these mineralized systems are similar in
nature and with similar upside exploration potential for bonanza grade Au -Ag polymetallic epithermal
deposits.
“These age-date results are proof of our concept that our properties are part of a continuous belt of
caldera systems that have shown exceptional potential for hosting bonanza grade Au -Ag epithermal
deposits,” said David Jones, Exploration Manager and Director of Madoro Metals. “The calderas
associated with Gold Resource Corp.’s producing Arista -Switchback mine are indistinguishable in age
from the dates obtained from our Yautepec project. We are encouraged to have formally demonstrated
the contemporaneity of our Yautepe c project caldera with the ages of nearby producing mines along
this rapidly emerging Au-Ag belt.”
U-Pb ages obtained from 4 distinct calderas (D. Jones unpublished mapping, 2000 -present) are
presented in the following table:

The results indicate that:
• The 3 calderas associated with Gold Resource Corp .’s active Arista-Switchback mine and related
epithermal systems all developed between approximately 19-18 Ma (million years ago).
• The caldera system associated with the Company’s Yautepec project developed in a similar age
range of approximately 19-18 Ma.
• The similarities in ages indicate that the area of Gold Resource Corp .’s producing mines and
Madoro’s Yautepec entire project area is part of a singular magmatic -structural-hydrothermal
system spanning 60 -kilometers distance; the entire trend may be considered to have similar
potential for high-grade epithermal Au-Ag polymetallic deposits
Accompanying F igures 1 -3 show, respectively, the locations of identified caldera systems relative to
active mining and exploration efforts, the locations of samples for the age dates in Table 1, and our
inference of the significance of these results.

Mr. David Jones, Exploration Manager and Director of Madoro Metals, will be presenting these findings
at the Discoveries Mining Conference from October 5 -7, 2021 in the mining capital of Mexico
Hermosillo, Sonora, where he will be speaking ( https://www.discoveriesconference.com ). Mr. Jones’
presentation will incorporate what these findings mean for the emerging Au -Ag polymetallic belt of
Oaxaca, Mexico, and the potential for exploration success on Madoro Metals’ properties.
About Madoro Metals Corp.
Madoro Metals Corp . ( MDM | TSX Venture Exchange; MSTXF | OTC ) is a Mexico -focused precious
metals company actively engaged in exploration and development of three gold -silver projects in the
state of Oaxaca, Mexico. The Yautepec , Magdalena, and Rama de Oro projects each consist of large
epithermal systems that are highly prospective for precious metals in structural and geologic settings
like those of nearby producing mines. Systematic exploration has advanced two of the projects towards
drilling with the intention of discovering an economic mineral deposit.
