Reyna Silver Encounters Multiple High-Grade Sulphide Zones Within 54.9 Metres of Near-Source Style Skarn at Guigui
VANCOUVER, BC and HONG KONG, CHINA / ACCESSWIRE / October 28, 2021 / Reyna Silver Corp. (TSXV:RSLV; OTCQX:RSNVF; FRA: 4ZC) ("Reyna" or the "Company") is pleased to report initial results for its 13-hole Phase 1 drilling program on its 100% owned Guigui Project in central Chihuahua, Mexico. The program was designed to narrow down the location of the probable source intrusion for the Santa Eulalia District- Mexico's largest known Carbonate Replacement Deposit (CRD). Two holes have cut a previously unknown rhyolitic intrusion over 200 m thick that has extensive high-grade sulphide mineralization along its base. The most significant hole was GG21-28 which intersected 54.90 m (core length) of pervasive multi-stage epidote skarn alteration cut by at least 4 overprinted sulphide mineralization stages. Individual sulphide stages show distinctive silver, lead, zinc, and copper grades indicative of repeated pulses of mineralizing fluids (Figure 2 and Table 1). This combination of repeated sulphide mineralization overprinting pervasive high-temperature alteration ("skarn") within a highly felsic intrusion strongly suggests that Hole GG21-28 lies close to the undiscovered source of the Santa Eulalia CRD system.
"We are very pleased that our broadly-spaced systematic drilling program appears to have led us to the threshold of the source of this important historic district. Our main goal for Phase 1 was to locate high-grade mineralization associated with the right style of intrusion, and it turns out we have discovered not only the largest intrusive ever found in the district, but it's the first mineralized skarn ever seen in Guigui." stated Jorge Ramiro Monroy, Reyna Silver's CEO. "We are well funded and look forward to additional success from our aggressive follow-up Phase 2 drilling program".

The entire 54.90 m skarn zone in GG21-28 is mineralized, but there are 4 principal sulphide-rich stages starting 1300 m downhole (Table 1). The uppermost sulphide zone is silver-rich, averaging 184 g/t (5.9 oz/t) Silver over 2.3 m (core length), but this includes a 0.59 m interval of 523 g/t (16.8 oz/t) Silver. Beneath this is a higher Zinc (to 18.35% Zn) zone with distinctly lower Silver. Following a zone of weakly sulphidized skarn lies a narrow Copper-rich stage (to 1.58% Cu) with moderate Zinc. The lowest 15 m of the mineralized skarn is the most pervasively mineralized and shows consistently high Zinc (to 15.2% Zn) with relatively low Lead except for a discrete galena-rich band grading 10.5% Lead and 99 g/t Silver.
"This is exactly what our exploration model says you should expect to see when approaching the hub of a major CRD mineralization center", said Dr. Peter Megaw, Reyna Silver's Chief Exploration Advisor. "These successive sulphide stages provide strong evidence for the passage of repeated pulses of mineralizing fluids that emanated from a nearby, probably multiphase intrusive center that we are closing in on. This is a breakthrough that means we now have a starting point for exploring upwards into the thick overlying limestone package - where the sulphides should become higher grade, while simultaneously trying to pin down the source intrusion - where the skarn should become more extensive and better mineralized. We eagerly look forward to fleshing out both legs of our CRD model with our Phase 2 drilling".
Now that the general source area has been located, a fully funded and permitted, two-pronged 8,000 m Phase 2 drilling program has begun working upwards and outwards from Hole GG21-28. One focus will be to trace the mineralization upwards into limestones, where silver-rich mineralization like that seen at the top of the GG21-28 intercept may be both larger and extend closer to the surface. The other focus will be to trace the sulphide mineralization and related skarn alteration sourceward where the volume of mineralization can be expected to expand.
