MSTXF - Madoro Metals Receives Positive Results from its Age-Dating Rock Analysis in Oaxaca Mexico
(TheNewswire)
Results to be presented at theupcoming October 5-7, 2021 Discoveries Mining Conference inHermosillo, Mexico
September 29, 2021 - TheNewswire - Vancouver, BC, Canada - MadoroMetals Corp. (“ Madoro ” or the“ Company ”) (TSXV:MDM) (OTC:MSTXF)(WKN:A2QQ1X) , a mineral explorationcompany focused on Mexico, is pleased to announce results from alimited program of uranium-lead (“U-Pb”) age dating on selectedcaldera-system (supervolcano) rocks from the region of its activeexploration programs in the state of Oaxaca. The study was undertakento better quantify the relative ages of rocks associated with gold,silver, and base metal mineralization at the Company’s projects andcompare these to the ages of similar rocks from the areas of nearbyproducing mines (e.g.: Gold Resource Corporation’s Arista-Switchbackand Alta Gracia mines), which lie approximately 30 kilometers alongtrend from the Company’s property. It was previously speculated,based on our understanding of local and regional geologic controls,that these mineralized systems are similar in nature and with similarupside exploration potential for bonanza grade Au-Ag polymetallicepithermal deposits.
“These age-date results are proof of our concept that our propertiesare part of a continuous belt of caldera systems that have shownexceptional potential for hosting bonanza grade Au-Ag epithermaldeposits,” said David Jones, Exploration Manager and Director ofMadoro Metals. “The calderas associated with Gold Resource Corp.’sproducing Arista-Switchback mine are indistinguishable in age from thedates obtained from our Yautepec project. We are encouraged to haveformally demonstrated the contemporaneity of our Yautepec projectcaldera with the ages of nearby producing mines along this rapidlyemerging Au-Ag belt.”
U-Pb ages obtained from 4 distinct calderas (D. Jones unpublishedmapping, 2000-present) are presented in the following table:

The results indicate that:
-
- The 3 calderas associated with Gold Resource Corp.’s activeArista-Switchback mine and related epithermal systems all developedbetween approximately 19-18 Ma (million years ago).
- The caldera system associated with the Company’s Yautepec projectdeveloped in a similar age range of approximately 19-18 Ma.
- The similarities in ages indicate that the area of Gold ResourceCorp.’s producing mines and Madoro’s Yautepec entire project areais part of a singular magmatic-structural-hydrothermal system spanning60-kilometers distance; the entire trend may be considered to havesimilar potential for high-grade epithermal Au-Ag polymetallicdeposits
Accompanying Figures 1-3 show, respectively, thelocations of identified caldera systems relative to active mining andexploration efforts, the locations of samples for the age dates inTable 1, and our inference of the significance of theseresults.

Mr. David Jones, Exploration Manager and Director ofMadoro Metals, will be presenting these findings at the Discoveries Mining Conference from October 5-7, 2021 in the mining capital of MexicoHermosillo, Sonora, where he will be speaking ( https://www.discoveriesconference.com ). Mr. Jones’ presentation will incorporate what thesefindings 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 VentureExchange; MSTXF | OTC) is a Mexico-focused precious metals company activelyengaged in exploration and development of three gold-silver projectsin the state of Oaxaca, Mexico. The Yautepec, Magdalena, and Rama deOro projects each consist of large epithermal systems that are highlyprospective for precious metals in structural and geologic settingslike those of nearby producing mines. Systematic exploration hasadvanced two of the projects towards drilling with the intention ofdiscovering an economic mineral deposit.
