Kingman Engages Burgex to Conduct Underground Sampling and Technical Reassessment at Rosebud Mine

Core Viewpoint - Kingman Minerals Ltd. has engaged Burgex Mining Consultants to conduct underground sampling and metallurgical testwork at the historic Rosebud Mine as part of a technical reassessment program aimed at refining geological interpretations and guiding future exploration decisions [1][2]. Group 1: Program Objectives and Scope - The program aims to document the underground geometry and vein exposures within the historic workings and collect material for laboratory testing [2]. - Key elements of the program include underground access and evaluation starting at the 100-foot level, with further access to be evaluated based on conditions [5][6]. - The program will also include a LiDAR survey for three-dimensional mapping of the mine [10]. Group 2: Historical Context and Previous Work - The Rosebud Mine has a history of intermittent gold and silver mining dating back over 140 years, with significant activity in the late 1920s and early 1930s [3]. - Previous reconnaissance phases in 2020 yielded high-grade assay results, including up to 252 g/t gold and 341 g/t silver from the 100-foot level, and up to 688 g/t gold and 468 g/t silver from the 200-foot level [7][8]. - These earlier sampling efforts have informed the design and sequencing of the current reassessment program [12]. Group 3: Management Commentary - The Interim CEO, Simon Studer, emphasized that recovering material from multiple underground exposures is crucial for understanding the historical mining operations and addressing uncertainties regarding mineral continuity and metallurgical response [4].
