Silverco Mining Intersects High-Grade Silver at Cusi, Including 1,100 g/t Ag over 10.3 Metres
Silverco’s Promontorio infill hole returned 11,330 g*m Ag, a world-class grade-width metric near known stopes.
Silverco Mining Ltd. (SICO) has released new underground drill results from the Promontorio zone of its 100%-owned Cusi silver-lead-zinc-gold project in Chihuahua, Mexico. The data is part of the company’s 2026 30,000 m drilling program.
Key intercepts from the program include:
- Hole UGCU26-08: 1,100 g/t Ag (1,080 g/t AgEq) over 10.3 m, including 6,350 g/t Ag (6,452 g/t AgEq) over 0.7 m.
- Hole UGCU26-07: 198 g/t Ag (217 g/t AgEq) over 7.7 m, including 1,002 g/t AgEq over 0.9 m.
- Hole UGCU26-08 (second interval): 234 g/t Ag (260 g/t AgEq) over 5.5 m.
- Hole UGCU26-05: 247 g/t Ag (236 g/t AgEq) over 5.4 m.
- Hole UGCU26-06: 134 g/t Ag (148 g/t AgEq) over 8.2 m, including 611 g/t AgEq over 0.3 m.
The company noted that the high-grade zone identified in UGCU26-08 lies 25 m below existing development and supports the Preliminary Economic Assessment (PEA) mine plan. AgEq calculations utilized metal prices of $30/oz Ag, $2,400/oz Au, $1.00/lb Pb, and $1.35/lb Zn, with recoveries set at 90% for Ag, 50% for Au, 90% for Pb, and 60% for Zn.
Silverco Mining Ltd. (SICO) is currently a producer at its La Negra mine, which is operating at 55% capacity, with a restart of the Cusi mine targeted for late 2026. The company’s market capitalization of approximately C$411 million already embeds significant value for both assets. A single infill hole at Cusi, even if it yields world-class grade-thickness, does not materially change the estimated resource or mine economics. The Preliminary Economic Assessment (PEA) already contemplates high-grade veins; while this hole may improve early cash flows slightly, the company’s value drivers remain production ramping at La Negra and the execution of the Cusi restart.
The stock has been in a persistent downtrend from its February high of $14.65 to $7.55. This news is unlikely to reverse that trend because the market already expects high-grade hits at Cusi and is more concerned about financing dilution, restart delays, and silver price volatility.
Silverco Mining Ltd. (SICO) owns the producing La Negra silver mine, which it acquired in May 2026, as well as the Cusi project, a past-producing, fully-permitted silver restart. The Cusi project’s preliminary economic assessment outlines a nine-year mine life with an annual production of 2.5 million ounces of silver equivalent at an all-in sustaining cost of US$26.75 per ounce, providing strong leverage to silver prices. The company aims to become a 10 million ounce per year producer within three years.
