Core Insights - Aurania Resources Ltd. has identified a significant zone of hydrothermal alteration at its Awacha project in Ecuador, following a detailed Anaconda-style mapping program conducted in 2024 [1][2][3] - The identified zone is associated with a magnetic high anomaly and elevated Mobile MagnetoTellurics (MobileMT) conductivity, indicating potential for further exploration and drilling [1][5] Data Interpretation and Expert Review - The data interpretation was completed in early June 2025, with porphyry copper expert Dr. Steve Garwin engaged to assess the mapping data and identify promising targets [2] - Dr. Garwin recommends detailed mapping at a scale of 1:1,000 to 1:2,000 to establish drill pad locations and suggests extending soil sampling coverage over identified MobileMT anomalies [2] Geological Characteristics - The hydrothermal alteration zone measures over 6 km by 4 km and affects Mesozoic hornblende-bearing intrusions within Jurassic siliciclastic rocks [3] - The alteration features an early-stage propylitic assemblage, with subsequent stages including potassic, phyllic, argillic, and advanced argillic alterations [3] Surface Sampling Results - Rock-chip sampling at the surface has yielded significant results, including up to 0.37% Cu, 0.20 g/t Au, and elevated levels of As, Bi, and Mo [4] - Elevated Cu:Zn ratios and the presence of chalcopyrite indicate proximity to the mineralized core, with a defined target zone of approximately 2 km in diameter located southwest of the central argillic zone [4][5] Target Zone Delineation - Dr. Garwin has delineated a target zone of 2,200 m x 1,200 m, supported by magnetic high anomalies and elevated MobileMT conductivity [5] - These anomalies suggest the presence of potassic alteration and electrically conductive sulphide minerals, which are indicative of mineralized porphyry systems [5]

Core Insights - Aurania Resources Ltd. has reported the discovery of six highly conductive anomalies at its Awacha porphyry copper target in Ecuador through the reprocessing of Mobile MagnetoTellurics (MobileMT) data using advanced 2D inversion technology [1][3]. Group 1: Technology and Methodology - In 2021, Aurania contracted Expert Geophysics Surveys Inc. to conduct a MobileMT airborne survey over the Awacha area, initially using a one-dimensional (1D) algorithm for electromagnetic (EM) data inversion [2]. - Recent advancements in EM inversion technology led Aurania to reprocess the existing MobileMT data with a more comprehensive 2.5D code, which accounts for the area's topography, resulting in improved lateral and vertical resolution [2]. Group 2: Findings and Implications - The new inversion data confirmed the presence of six high-conductivity anomalies starting approximately 250 meters from the surface, which are significant as they often correlate with porphyry copper deposits due to the presence of conductive sulphide minerals [3]. - The MobileMT 2.5D inversion results will be integrated with data from the Anaconda mapping program completed in 2024, with expert Dr. Steve Garwin reviewing the data to identify promising porphyry targets [4]. Group 3: Company Overview - Aurania is focused on the exploration of mineral properties, particularly precious metals and copper, in South America, with its flagship asset being The Lost Cities – Cutucu Project located in Ecuador [9].
