ON MEXICO ISSUES

  • Endeavour Silver Corp., reported the best drilling intercepts in Mexico on the first week of June 2025. Details are shown in the table below:

ON EXPLORATION

  • Pinnacle Silver and Gold Corp., presented underground sampling results from the Pinos Cuates mine at its Potrero project in Durango. The systematic channel sampling of the underground workings has defined lens of high-grade gold and silver mineralization, with individual samples returning up to 37.3 g/t Au and 346 g/t Ag. Composite channel sampling at Pinos Cuates mine returned assays up to 19.4 g/t Au and 266 g/T Ag over 4.1m, including 37.3 g/t Au and 346 g/t Ag over 0.6m, and 31.2 g/t Au and 395 g/t Ag over 0.5m. Underground mapping on the Dos de mayo vein revealed that the vein-breccia system is wide and strong with exposed widths of 10.46m and 8.5m on the upper and lower level respectively, but it still needs to drill to find the full extent. Surface mapping on the Dos de mayo vein system extended the mineralized zone over 1.6km, with grab samples strikingly high gold and silver results like one spot with 13.2 g/t Au and 2,280 g/t Ag, and 5.2 g/t Au and 745 g/t Ag. Visible gold and ginguro textures were observed during the mapping field work. These results demonstrate strong exploration potential and the possibility for near-term development of the high-grade mineralization.
  • Mithril Silver and Gold Limited released high-grade mineralization surface and underground sampling results from target 5 along a 1.6km vein corridor within its Copalquin project in Durango, with grades exceeding 1% copper, lead, and zinc, along with significant Au and Ag in a large area. Highlights channel samples results include 2.84 g/t Au and 777 g/t Ag over 0.8m (Mina Apomal); 5.36 g/t Au and 706 g/t Ag over 0.5m (Apomal Norte); 2.58 g/t Au and 716 g/t Ag over 0.8m (Dulces Nombres); 1.48 g/t Au, 236 g/t Ag, 0.17% Cu, 1.7% Pb, and 0.06% Zn over 1m (Veta Azul); 0.04 g/t Au, 8 g/t Ag, 0.03% Cu, 0.1% Pb, and 1.3% Zn over 1m (Veta Azul); 0.07 g/t Au, 41 g/t Ag, 1.6% Cu, 19 ppm Pb, and 61 ppm Zn over 1m (Apomal); and 0.06 g/t Au, 145 g/t Ag, 0.1% Cu, 1.1% Pb, and 0.05% Zn over 0.85m (Duraznito). These findings reinforce the district’s potential for multiple high-grade deposits and support ongoing resource development efforts Drilling at this target area is set for next quarter after finishing up work in the main resource zone and updating their geological model.

ON MINING

  • Orogen Royalties Inc., presented Q1, 2025 production and financial results. A total of 270,203 tonnes were processed at Ermitaño Mine by First Majestic Silver Corp., with grades of 58 g/t Ag and 2.59 g/t Au and metallurgical recoveries of 68% and 95% respectively. The company reported a net income from operations of CAD $1.8M; royalty revenue of CAD $2.1M from 497 Gold Equivalent Ounces (GEO´s) on average price of USD $2,820 per ounce as a result of the 2% NSR that Orogen holds at Ermitaño; revenue from prospect generation activities of CAD $0.5M; G&A expenses of CAD $1-7M; cash flow of CAD $1.2M; and working capital of CAD $28M at March 31, 2025.

ON FINANCING

  • Defiance Silver Corp., announces brokered  Listed Issuer Financing Exemption (LIFE) offering for gross proceeds of up to CAD $8M for the sale of up to 32,000,000 units at a price of CAD $0.25 per unit.

Later on, the company upsized the offering to 52,000,000 units at a price of CAD $0.25 per unit for gross proceeds of up to CAD $13M. Concurrent with the brokered offering, the company plans to complete a non-brokered private placement of up to 6,000,000 units of the Company (the “NB Units”, and collectively with the Units, the “Offered Securities”) at a price of CAD $0.25 per NB Unit for additional gross proceeds of up to CAD $1.5M. Defiance plans to use the gross proceeds to complete a Mineral Resource Estimate at its San Acacio project in Zacatecas, to make periodic cash option payments on its Tepal project in Michoacan, and to provide general working capital to support operations.
  • Vizsla Royalties Corp., entered into a bought deal agreement with CIBS Capital Market to sell 27,400,000 common shares at a price of CAD $2 per common share for gross proceeds of CAD $54.8M. Gross proceeds will be used to repurchase 50% of the 3.0% NSR for USD $1.95M and will purchase the remaining 50% of the 3.0% NSR for USD $38.05M, for a total cash consideration of USD $40M subject to potential adjustment in customary circumstances (Panuco project, Sinaloa).

With the first tranche closing of CAD $3,930,711, this brings the total oversubscribed financing to CAD $5,206,031. Impact Silver plans to use the net proceeds to accelerate exploration activity at its Plomosas high-grade zinc-lead-silver property in Chihuahua, further develop its prolific silver assets at its legacy Royal Mines of Zacualpan district in Estado de Mexico, as well as invest in operational improvements to improve productivity and throughput. Exploration activities include sampling, target definition, and drilling with the intention of expanding the existing JORC mineral resource at Plomosas mine where exploration potential is exceptional along a 6 km-long structure.  
  • Silver Storm Mining Ltd., announced that it closed the first tranche of its previously announced brokered LIFE financing for gross proceeds of CAD $10,541,050 from the sale of 81,085,000 units at a price of CAD $0.13 per unit, including a CAD $1M investment by Eric Sprott.

ON RESOURCES AND DEVELOPMENT

  • Endeavour Silver Corp., reported positive results from its drilling exploration program at Pitarrilla project, Durango. Drilling from surface and underground has been successful in intersecting high-grade silver, zinc and lead mineralization and provides additional confidence required to upgrade existing mineral resources. Drilling highlights are shown in the table below:
  • Orla Mining Ltd., delivered initial underground Mineral Resource Estimate (MRE) for its Camino Rojo property in Zacatecas. Measured and indicated mineral resources are 50.1M tonnes of 2.45 g/t Au, 10.6 g/t Ag, and 0.25% Zn (2.58 g/t AuEq), totaling 3.95M Oz Au, 17.05M Oz Ag, and 278M Lb Zn (4.16M Oz AuEq). Inferred mineral resources are 5.6M tonnes of 2.21 g/t Au, 10.9 g/t Ag, and 0.21% Zn (2.33 g/t AuEq), totaling 0.4M Oz Au, 1.95M Oz Ag, and 26M Lb Zn (0.42M Oz AuEq). Orla´s strategy is “to advance the initial underground MRE towards possible future construction decision. This include additional exploration, development planning for an exploration drift to allow for tighter spaced underground drilling, flowsheet design, further metallurgical testing, engineering studies, and permitting activities”.
