Globenewswire· 2025-09-16 10:59
Core Insights - Mirasol Resources Ltd. has identified the 46 South target as a high-priority drill target within its 100%-owned Sobek Copper-Gold-Silver Project in Chile, supported by geochemical soil surveys and IP ground geophysics [1][3][12] Group 1: Project Overview - The Sobek Project is located in the Vicuña District of Chile, near significant deposits such as Filo del Sol and Lunahuasi, with the 46 South target situated at the southern end of a 3-km N-S trending corridor [2][14] - The 46 South target is characterized by a large copper-gold-molybdenum geochemical anomaly measuring approximately 1.0 × 0.7 km, with maximum soil values of 275 ppm copper, 37 ppm molybdenum, and 88 ppb gold [6][9] Group 2: Geophysical and Geological Data - Airborne surveys have completed 2,700 line kilometers of magnetics and over 500 line kilometers of MT, revealing a district-scale magnetic high and an MT anomaly at depth beneath the 46 South target [4][5] - The geophysical data indicates a strong cylindrical magnetic susceptibility anomaly and a sharp resistivity contrast starting at elevations of approximately 4,600–4,500 masl, suggesting the presence of a porphyry system [7][10] Group 3: Exploration Strategy - An innovative Deep Vector IP and MT geophysical survey will be deployed to refine the geometry of the targets ahead of the anticipated drill program launch in early November [11][12] - The integration of various geophysical and geochemical datasets establishes 46 South as a compelling undrilled target, with plans for the first drill hole to test the overlapping soil anomaly and underlying mineralized systems [12][14]
Large Scale Epithermal System and Porphyry Potential Highlighted by MobileMT Survey at Great Pacific Gold's Wild Dog Project

Core Insights - Great Pacific Gold Corp. has reported significant findings from its Wild Dog Project in Papua New Guinea, highlighting both an extensive epithermal system and the potential for a major porphyry system nearby [1][3][5]. Group 1: Project Overview - The Wild Dog Project is located on New Britain Island, Papua New Guinea, and features a large-scale epithermal target with a strike length of over 15 kilometers and a depth extension exceeding 1,000 meters [1][5][32]. - A diamond drill program is currently in progress, targeting high-priority areas within a 1.5 km strike length of the epithermal vein structural corridor [2][5]. Group 2: Drilling Results - Drilling results from the Phase 1 program have shown high-grade mineralization, with hole WDG-02 intercepting 7.0 meters at 11.2 g/t AuEq, which includes 5.5 g/t Au, 68.8 g/t Ag, and 3.1% Cu [2][5][32]. - The current drilling program is only testing about 10% of the overall structure, indicating significant potential for further discoveries [5]. Group 3: Geophysical Survey Insights - The MobileMT geophysical survey has revealed the scale of the epithermal system and indicated the presence of a substantial porphyry system adjacent to the epithermal vein structure, similar to the Wafi-Golpu project [3][11]. - The processed MobileMT data has identified a large resistivity and magnetic anomaly at the Magiabe target, interpreted as a potassic-altered intrusive body measuring approximately 1,000 meters in diameter and extending to over 2,000 meters in depth [11][20]. Group 4: Future Exploration Plans - The Magiabe target is expected to be a priority for exploration, with plans to advance it towards drill-readiness by 2026, including detailed mapping and additional geochemical sampling [19][20]. - Great Pacific Gold anticipates initiating the first drill testing of the Magiabe porphyry system by 2026, leveraging its strong geophysical and geochemical signatures [20][32].
American Pacific Drills 10.2 g/t Gold over 7.6 Metres Including 44.1 g/t Gold over 1.5 Metres and Demonstrates Link Between Historic Broadway and Madison Mine Areas

Core Insights - American Pacific Mining Corp. has reported significant drilling results from its Madison Project, demonstrating a structural and stratigraphic link between the historic Broadway and Madison mines, which could indicate a larger mineralized system at depth [1][4][7]. Drilling Results - The final six reverse circulation drill holes from Phase I 2025 revealed an upper zone in hole APMMAD25-08 with 44.1 g/t Au over 1.5 m within a broader interval averaging 10.2 g/t Au over 7.6 m [5][13]. - Additional significant results include 0.5% Cu over 27.4 m and 0.7 g/t Au over 16.8 m in hole APMMAD25-05, and notable pathfinder mineralization in APMMAD25-06 [5][6]. Geological Insights - The drilling results validate the geological model, confirming that the Broadway and Madison mines are part of a broader mineralized corridor, which was not identified in past exploration efforts [6][8]. - The presence of elevated bismuth tellurides and other pathfinder minerals supports the interpretation of a robust mineralizing system at depth, indicating potential for a deeper porphyry system [6][13]. Future Exploration Plans - The next phase of drilling is set to commence in the second half of 2025, utilizing data from Phase I to refine drill targets aimed at delineating a potentially substantial buried porphyry [4][13]. Historical Context - Historical mining at the Broadway mine yielded gold grades averaging 9.9 g/t Au for 144,000 ounces from 1870 to 1942, indicating a rich mining history that enhances the current exploration potential [8][20]. Economic Potential - Select drill holes testing historic material returned significant values, with APMMAD25-03 showing 0.7 g/t Au, 20.8 g/t Ag, and 0.3% Cu over 10.7 m, suggesting that previously considered waste material may provide future cash flow opportunities [14][20].
