Core Viewpoint - Pinnacle Silver and Gold Corp. has confirmed strong gold-silver mineralization in the Estrella Vein at the El Potrero project in Mexico, indicating significant potential for further exploration and development [1][3]. Group 1: Estrella Vein Findings - Surface and underground sampling of the Estrella Vein revealed two mineralized zones with grades of 5.49 g/t Au and 48 g/t Ag over 0.72 metres, and 1.87 g/t Au and 51 g/t Ag over 1.1 metres [1]. - Individual samples from the Estrella Vein assayed up to 17.7 g/t Au and 24 g/t Ag over 0.5 metres, and 3.51 g/t Au and 196 g/t Ag over 0.8 metres [1]. - The vein has been traced for nearly 150 metres along strike and is open in both directions, with a maximum width of 6.0 metres at the northern end [1]. Group 2: La Dura 2 Mine Developments - Surface sampling at the La Dura 2 mine has extended the known mineralization to approximately 45 metres, with notable assays including 6.89 g/t Au and 208 g/t Ag over 1.4 metres [2]. - The identification of higher-grade mineralization at La Dura 2 has more than tripled the known strike length of this mineralized zone [4]. Group 3: Geological Context and Exploration Potential - The Estrella vein is located approximately 500 metres southwest of the main Dos de Mayo structure, suggesting significant vertical continuity of the epithermal system [3]. - The geological characteristics of the vein, including brecciated textures and the presence of clay minerals, indicate it is part of a low-sulphidation epithermal system [3]. - The intersection of the Estrella vein with the Dos de Mayo structure could be a significant locus for mineralization, extending the Estrella structure by 600-800 metres [5]. Group 4: Sampling and Quality Assurance - A total of 62 underground channel samples were taken, with 35% of gold assays exceeding 1.0 g/t Au and 27% of silver assays exceeding 31 g/t Ag [6]. - Systematic chip channel sampling was conducted to ensure accurate representation of the mineralized structures [8]. Group 5: Project Overview - The El Potrero project is located in the Sierra Madre Occidental region of Mexico, near several operating mines, indicating a favorable mining environment [13]. - The property has significant exploration potential due to its history of limited systematic exploration [14]. - A previously operational 100 tpd plant can be refurbished for near-term production once permits are secured [15].
Pinnacle Identifies Gold-Silver Mineralization at Historic La Dura Mine, Extending Mineralized Horizon to Almost 500 Metres

Core Insights - Pinnacle Silver and Gold Corp. has reported significant sampling results from the historic La Dura mine at the El Potrero gold-silver project in Durango, Mexico, indicating an extension of the mineralized strike length along the Dos de Mayo vein structure to nearly 500 metres, with untested gaps between principal mines [1][3] Group 1: Sampling Results - The La Dura mine features a main adit extending approximately 60 metres along the vein, with two smaller adits collectively known as La Dura 2, which have shown consistent mineralization [2] - Channel sampling has revealed an average grade of 1.98 g/t Au and 98 g/t Ag over a 12 metre strike length, with individual grades reaching up to 4.51 g/t Au and 269 g/t Ag over 0.5 metres [2] - The mineralized zone is only partially exposed, suggesting significant potential for expansion through further mine development and drilling [2][3] Group 2: Exploration Potential - There is approximately 150 metres between La Dura and the Pinos Cuates mine, where previous sampling returned grades of up to 85 g/t Au and 520 g/t Ag over 0.5 metres, indicating further drill testing is warranted [3] - An additional 120 metres of untested strike potential exists between Pinos Cuates and the Dos de Mayo mine, along with over 1,000 metres to the northwest of La Dura, all of which are planned for drill-testing once surface permits are secured [3] Group 3: Geological Context - Surface and underground mapping is currently focused on a north-south trending vein called La Estrella, located approximately 500 metres southwest of the Dos de Mayo trend, which may indicate significant mineralization potential due to the intersection of structural trends [4] - The El Potrero project is situated in the Sierra Madre Occidental, an area known for high-grade gold-silver mineralization within a low sulphidation epithermal breccia vein system [11][12] Group 4: Project Development - The property has a previously operational 100 tpd plant that can be refurbished for near-term production, with the site being road accessible and within three kilometres of a power line [13] - Pinnacle aims to earn an initial 50% interest upon commencing production, with plans to generate cash flow for further project development and increase ownership to 100% subject to a 2% NSR [14] Group 5: Company Overview - Pinnacle Silver and Gold Corp. is focused on developing precious metals projects in the Americas, with a commitment to building long-term, sustainable value for shareholders [15]
Pinnacle Delineates New Vein at El Potrero as Robust Epithermal System Takes Shape
Thenewswire· 2025-09-24 12:30
Core Viewpoint - Pinnacle Silver and Gold Corp. has identified a robust low sulphidation epithermal system at the Potrero project in Durango, Mexico, with significant gold-silver mineralization extending from underground to surface, particularly at the El Capulin vein, which is approximately 200 meters southwest of the Dos de Mayo vein [1][2][3]. Group 1: Mineralization and Sampling Results - Surface mapping and sampling have revealed high-grade gold-silver mineralization over a vertical distance of up to 80 meters, with notable grades of 2,280 g/t Ag and 1,444 g/t Ag at surface [2][3]. - The El Capulin vein has been traced for approximately 375 meters along strike, with grades reaching up to 6.27 g/t Au and 99 g/t Ag, indicating strong continuity of mineralization [3][6]. - The vertical extension of mineralization suggests potential for further discoveries, with mineralization possibly extending downwards to the 1500 masl level seen at Dos de Mayo [6][7]. Group 2: Project Potential and Infrastructure - The Potrero project is located in the Sierra Madre Occidental, near several operating mines, enhancing its strategic value [15][16]. - The property has significant exploration potential as it has not been systematically explored by modern methods for nearly 40 years [16]. - A previously operational 100 tpd plant on site can be refurbished for near-term production, with existing infrastructure such as road access and power lines within proximity [17][18]. Group 3: Company Strategy and Ownership - Pinnacle aims to earn an initial 50% interest in the project upon commencing production, with plans to generate cash flow for further development and increase ownership to 100% [18][20]. - The company is focused on developing precious metals projects in the Americas, with a commitment to building long-term, sustainable value for shareholders [20].
