Viszla Silver (TSXV:VZLA) has reported new results from 19 new drill holes at the Tajitos – Copala resource area at the Panuco silver-gold project in Mexico. The company’s intercepts are a part of the ongoing 2022 infill-expansionary drill program at the Copala and Cristiano structures in the western section of the district.
Infill results now support grade continuity in the south-central portion of the Copala structure. Continued resource expansion drilling to the north and southeast highlights that mineralization remains open.
Michael Konnert, President and CEO commented in a press release: “The Copala structure continues to impress with high precious metals grades over very broad width. Infill drilling within the Tajitos-Copala resource area continues to highlight exceptional mineral continuity marked by multiple intervals grading well over 1,000 grams per tonne, while expansionary drilling to the north and southeast demonstrate a growing high-grade footprint. Additionally, at Cristiano, drilling has now traced mineralization over 600 metres long by 300 metres deep. We note that Cristiano was not included in the maiden resource, however, given its near surface, high-grade continuity, we expect it will contribute materially to the pending resource update. We have had a phenomenal year of exploration success at Panuco and have expanded mineralization well beyond the March 2022 resource boundary at virtually every zone. Given the amount of new high grade drill results, inclusion of new mineralized structures, and the fast-approaching holiday season, we have elected to publish the resource update in early 2023. We are extremely pleased with the outcome of our 2022 programs and look forward to another outstanding year as we continue to grow and de-risk the Panuco Project in 2023.”
Highlights from the results are as follows:
- CS-22-205 returned 2,640 grams per tonne (g/t) silver equivalent (AgEq) over 5.30 metres true width (mTW) (2,101 g/t silver and 9.54 g/t gold)
- Including 4,563 g/t AgEq over 0.58 mTW (3,080 g/t silver and 23.60 g/t gold)
- CS-22-210 returned 561 g/t AgEq over 15.50 mTW (425 g/t silver and 2.31 g/t gold)
- And 2,044 g/t AgEq over 1.01 mTW (1,630 g/t silver and 7.34 g/t gold)
- CS-22-216 returned 905 g/t AgEq over 8.09 mTW (626 g/t silver and 4.48 g/t gold)
- CS-22-201 returned 3,340 g/t AgEq over 1.86 mTW (2,536 g/t silver and 13.65 g/t gold)
- CS-22-217 returned 1,862 g/t AgEq over 2.71 mTW (1,495 g/t silver and 6.56 g/t gold)
The Copala Structure is located in the western portion of the Panuco district at the northern extent of the Tajitos structure. Copala hosts high precious metals grades (up to 11,053 g/t silver and 33.50 g/t gold over 1.26 mTW) contained within a broader envelope of vein-breccia interlayered with host rock, up to 82 metres thick. Ongoing interpretations by Vizsla’s geologists suggest Copala has an average dip of ~46° to the east (~35° in its northern sector and steepening to ~52° in the southern sector).
Drilling at Copala has now traced mineralization along approximately 1,000 metres of strike length and approximately 400 metres down dip. High-grade silver-gold mineralization remains open to the north and southeast with ongoing detailed structural and geologic interpretations indicating the potential for mineralization to continue into the footwall side of the Tajitos Vein. The ongoing infill-drilling program, which consists of 25 holes drilled at 25 metre centers, was designed to assess grade continuity and to provide sample material for future metallurgical tests. To date, infill-holes CS-22-201, CS-22-205, CS-22-214, CS-22-216 and CS-22-218 have confirmed high-grade at tighter spacing. Additionally, step-out holes drilled to the east, particularly holes CS-22-202, CS-22-207 and CS-22-219, suggest an uplifted block of basement metasediments in fault-contact with andesites and diorite (see figures 2 and 4). Vizsla´s team is working on interpretations to determine the amount of displacement by the fault, to define a target elevation for Copala type mineralization on the footwall side (east) of the fault; i.e. an uplifted block on the east creates potential for Copala type mineralization at shallower elevation. Vizsla plans to test this hypothesis with drill-holes collared on the footwall side of the fault.
The Cristiano Vein is a precious metals rich structure located at the southwestern margin of the Copala structure. Cristiano is marked by a quartz-carbonate epithermal-vein striking N25°W that dips sub-vertical (85°) to the NE. Drill-holes intersecting Cristiano to date, highlight a high-grade zone plunging to the NW, with vertical extent of 300 metres and approximate strike length of 600 metres. The Cristiano Vein ranges in thickness from 0.7 mTW to 3.5 mTW, with a weighted average grade of 542 g/t silver equivalent.
The Cristiano Vein was initially discovered while targeting the Tajitos-Copala veins, where drilling intercepted the well-mineralized, NW-SE trending fault. Ongoing drilling has now led to new observations and interpretations allowing Vizsla geologists to plan drill holes specifically designed to explore Cristiano along strike and to depth. To the northwest, Cristiano intersects and offsets the Tajitos Vein, suggesting Cristiano post-dates Tajitos mineralization, thus creating a drill target on the footwall of Tajitos (Figure 3). Additionally, open ended intercepts to the southeast suggest mineralization continues in this direction.

Table 1: Downhole drill intersections from the holes reported for the new splay vein at the foot wall of Copala. Note: AgEq = Ag g/t x Ag rec. + (Au g/t x Au Rec x Au price/gram)/Ag price/gram. Metal price assumptions are $20.70/oz silver and $1,655/oz gold and metallurgical recoveries assumed are 93% for silver and 90% for gold. Gold and silver metallurgical recoveries used in this release are from metallurgical test results of the Napoleon vein (see press release dated February 17, 2022).
