Radiant(US:RLGT) Thenewswire·2026-01-20 13:30Core 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].
