Madoro Metals Corp.

VANCOUVER, BC / ACCESSWIRE / August 3, 2021 / Madoro Metals Corp. ("Madoro" or the "Company") is pleased to provide 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 (Figure 1). 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 discovery of well-mineralized polymetallic skarn along the western Yautepec caldera margin was realized through the disciplined application of Madoro's exploration model which, to date, has yielded remarkable success throughout the Yautepec project," said David Jones, Exploration Manager and Director of Madoro Metals. "These results indicate that we are dealing with a large mineralized epithermal and skarn complex which is integrated by the structurally-controlled magmatic-hydrothermal system of the Yautepec supervolcano. The geology is similar in nature to that seen at currently operating mines of the Oaxaca Ag-Au polymetallic belt. Discovery of these mineralized areas is a testament to the knowledge and dedication of our field team, all of whom have been involved with significant exploration successes throughout Mexico."

The following table summarizes rock chip geochemistry results from the western skarn-hornfels area:

Yautepec Project: Western Skarn Area Rock Chip Sampling Results (n = 20 -- ALS Labs)
	Element	Maximum value	Samples with Significant values	Lithology of highest value sample
Precious metals	Ag	1200 g/t	6 > 20 g/t; 12 > 1 g/t	Skarn zone of undetermined size/extent
	Au	n/a	n/a	Samples below detection
Base metals	Cu	3.97 wt%	10 > 100 ppm	Skarn zone of undetermined size/extent
	Pb	20.0 wt%	5 > 2.5 wt%; 19 > 100 ppm	Skarn zone of undetermined size/extent
	Zn	4.97 wt%	4 > 1.0 wt%; 15 > 300 ppm	Skarn zone of undetermined size/extent
	Mo	44.6 ppm	4 > 10 ppm	Massive oxide replacement of limestone
Pathfinder elements	As	2.74 wt%	14 > 0.50%; 26 > 1000 ppm	Skarn zone of undetermined size/extent
	Ba	1620 ppm	9 > 100 ppm	Skarn zone of undetermined size/extent
	Hg	1.37 ppm	2 > 1 ppm	Skarn zone of undetermined size/extent
	Sb	285 ppm	5 > 100 ppm	Skarn zone of undetermined size/extent
	Se	147.5 ppm	7 > 10 ppm	Skarn zone of undetermined size/extent
	Te	47.3 ppm	9 > 1.8 ppm	Skarn zone of undetermined size/extent
	Tl	4.83 ppm	4 > 0.50 ppm	Silicified hydrothermal breccia

The skarn-hornfels complex lies just outside of the recently mapped southwestern margin of the Yautepec caldera (Figure 2). 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' (i.e., 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.
