Madoro Metals Corp. provided an update on further exploration results from the southern portion of its Yautepec project. As described in a prior news release dated July 6, 2021, the Company recently discovered a 7-kilometer trend of previously unrecognized epithermal alteration and mineralization along the southern margin of the Yautepec supervolcano (caldera). Based on this success, Madoro's exploration team moved further west in search of the projected limit of the caldera. The anticipated western structural boundary of the supervolcano was found and a new area of skarn-hornfels alteration and mineralization was identified through field mapping. Preliminary rock chip sampling of mineralized skarn in this area yielded values up to 1.2 kilograms per ton Ag and 3.97 wt% Cu from a 0.10 meter grab sample. Skarn-hornfels alteration and variably present mineralization are found over an estimated area of at least a kilometer in outcrop, subcrop, and float, but the full extent of the complex has yet to be determined and remains open. The skarn-hornfels complex lies just outside of the recently mapped southwestern margin of the Yautepec caldera. The area lies 13 kilometers distant from similar polymetallic Ag-base metal mineralization found along the eastern caldera margin at the historically identified Las Minas area (under option by the Company per news release of October 16, 2019). These two mineralized skarn zones appear to be `mirror images' (that is, are symmetrical) across the 13-kilometer mapped east- west width of the supervolcano. The fact that similar styles of skarn mineralization occur at such a great distance demonstrates that the integrated Yautepec epithermal-skarn system is very large and has good potential to host a large and potentially economic deposit.
