“As at the historic Pinos Cuates mine, the existing underground workings at Dos de Mayo are giving us an important understanding of the nature of the gold-silver mineralization at El Potrero,” stated Robert Archer, Pinnacle’s President & CEO. “What we are seeing is consistent with these low-sulphidation epithermal systems, where pockets of high-grade mineralization (called “clavos” in Mexico) occur within a defined horizon, likely consistent with the “boiling zone” of the hydrothermal fluids.

GR Silver Mining Ltd. is pleased to announce that it has received a key 5-year drill permit for the San Marcial Area authorizing additional step-out and exploration drilling in an extensive area surrounding the current NI 43-101 Resource Area. The five-year Informe Preventivo issued by the Secretaría de Medio Ambiente y Recursos Naturales Mexico will allow for the drilling of step-out and exploration holes at 46 new drill sites in the San Marcial Area.

Pacifica Silver Corp. (CSE: PSIL) announced a Fall 2025 exploration program at its Claudia Silver-Gold Project in Durango, Mexico. The program includes an 8,000-metre Phase I drill campaign starting late September, targeting high-grade silver-gold veins, alongside surface sampling, geological mapping, and a 27-line km geophysical survey to enhance understanding and identify new drill targets.

Chesapeake Gold Corp. updates on its sulphide leach technology and Lucy exploration. Metates PFS metallurgical testwork advances positively, with third-party testing on three projects underway and new patents filed. At Lucy, a new 200m gold corridor (up to 1.33 g/t Au over 15m) and copper anomalies (up to 2% Cu) identified; project may extend 3km. Drilling planned post-current surveys.

GoGold Resources Inc. (TSX: GGD) announces initial 2025 near-mine exploration results at Los Ricos South Project, Mexico. Highlights: LRSGT-23-001 (41,110 g/t AgEq over 1.42m, incl. 28,094 g/t Ag & 173.6 g/t Au); LRGG-24-318 (904 g/t AgEq over 0.75m); LRGG-25-324 (1,034 g/t AgEq over 1.39m); LRGG-25-337 (849 g/t AgEq over 1.50m). Drilling extends Abra Zone down-dip and south, targeting 3.5km strike.

Kootenay Silver Inc. has launched a 50,000-meter drilling program at its Columba Silver Project in Chihuahua, Mexico, with two rigs targeting D and I-Vein extensions. Five drillholes (2,500m) are complete, with results pending. The program aims to expand the maiden 54.1 Moz silver Inferred Resource (284 g/t Ag). Fully funded, it seeks to update the MRE and explore a PEA.

Luca Mining Corp. reported high-grade results from its 2025 drilling at Tahuehueto Gold-Silver Mine, Durango, Mexico. Surface drilling at Santiago Deposit yielded 14.0m at 6.68 g/t Au and 6.0m at 9.0 g/t Au, with high-grade intercepts up to 23.1 g/t AuEq. Underground drilling confirmed Creston and Perdido vein continuity, with new breccia zones indicating resource expansion potential.

Sierra Madre Gold and Silver Ltd. (TSXV: SM) plans a two-stage expansion at its La Guitarra silver-gold mine in Mexico, boosting capacity from 500 tpd to 750-800 tpd by Q2 2026 (via paste fill plant, fourth ball mill, second cone crusher) and 1,200-1,500 tpd by Q3 2027 (new dry stack TSF, second crushing circuit). Fully funded from treasury and cash flow; no new permits needed.
