Northern Shield Resources (NSHR.F) Update Summary Company Overview - **Company**: Northern Shield Resources (NSHR.F) - **Date of Update**: July 21, 2025 Key Points Industry and Company Focus - The update primarily discusses the exploration activities and drilling results in the **conquest zone** and surrounding areas, focusing on mineralization and geological features relevant to precious metals and copper targets [1][2][3][4][5][6][7][8][9]. Drilling Results and Geological Findings - Drilling in the conquest zone revealed **Iolite alteration** in rhyolite, indicating potential for further exploration despite not yielding satisfactory results initially [2][4]. - A significant **hydrothermal breccia** was discovered, similar to findings in the Discovery Trench area, suggesting a broader hydrothermal system than previously understood [4][5]. - The presence of **ganguro banding** was noted, which is indicative of epithermal systems and suggests potential for high-value precious metals [10][15][34]. - **Visible gold** was observed in multiple drill holes, particularly in hole 26, which also showed signs of hydrothermal mineralization [11][21][22]. - The discovery of **tellurides** and **collaborate crystals** in the drilling samples indicates the presence of gold tellurides, which are significant for precious metal exploration [17][21]. Assay Results and Future Plans - The timeline for assay results is expected to be between **four to eight weeks**, with initial results anticipated in August 2025 [31][32][33]. - The company plans to conduct **downhole structural surveys** to guide future drilling programs, focusing on the orientation of mineralized structures [27][28][29][30]. Additional Insights - The geological features observed, such as **manganese carbonate alteration**, are classic indicators of proximity to epithermal systems, suggesting that the area may host significant mineralization [25][26]. - The update emphasizes the importance of **structural orientation** in drilling, as slight variations can lead to significant differences in mineralization outcomes [34][35][36]. - The exploration team is optimistic about the potential for discovering new mineralized zones, particularly in areas previously drilled that may have been overlooked [34][36]. Conclusion - Northern Shield Resources is actively exploring the conquest zone with promising geological findings that suggest potential for high-value mineralization. The upcoming assay results and structural surveys will be critical in determining the next steps for the company's exploration strategy [30][34].

The Promontorio Sur vein zone can be traced on surface for 1.5 km as quartz-carbonate veinlets hosted in andesitic agglomerate. The veinlets are interpreted as representing high levels of the epithermal system, with potential for high-grade mineralization at depth. Outcrop geochemical sampling shows anomalous values of silver, gold, and base metals along the structure. Minaurum drilling shows that the andesite overlies altered and mineralized limestone, with mineralization occurring at a fault contact betwe ...
