Core Viewpoint - Kobrea Exploration Corp. has received approval for mineral exploration activities across all its projects in the Western Malargüe Mining District, following the ratification of Environmental Impact Statements by the Mendoza provincial legislature [1][2][3] Group 1: Project Approvals - The Senate and Chamber of Deputies of Mendoza Province ratified Environmental Impact Statements for 27 exploration projects, allowing Kobrea to proceed with drilling and other exploration activities [1][3] - The approval process included extensive public hearings and technical analysis, demonstrating governmental support for mining in the region [3] Group 2: Company Overview - Kobrea Exploration Corp. focuses on the acquisition and exploration of base metal projects, holding rights to 7 projects covering over 733 square kilometers in southwestern Mendoza Province, Argentina [4] - The company is particularly focused on porphyry copper and copper-gold deposits, with multiple targets identified showing significant geological features [4] Group 3: Future Developments - Construction of access roads and an exploration camp is ongoing at the El Perdido Project, with a maiden diamond drilling program expected to commence shortly [1][2] - The approval of the San Jorge Project, located outside the Western Malargüe Mining District, is seen as a significant advancement for mineral exploration in Mendoza [2]
Hercules Metals Provides Update on 2025 Drilling at the Leviathan Porphyry System
Newsfile· 2025-10-08 11:10
Core Viewpoint - Hercules Metals Corp. is making significant progress in its 2025 drilling campaign at the Leviathan porphyry copper discovery, with a focus on both definition and exploration drilling to enhance shareholder value [2][3][4]. Drilling Progress - The company has completed sixteen drill holes and has one hole in progress at Leviathan, with two additional holes being drilled in the Southern Flats Zone, totaling over 13,000 metres drilled to date [2][4]. - Nine holes are currently awaiting assay results at the lab, indicating ongoing evaluation of the drilling outcomes [4]. Exploration Targets - The "Donut" Anomaly, a new target in the Southern Flats Zone, is being tested, showing a strong conductivity signature that is over three times the width of the Leviathan deposit [3][4]. - The Footwall Zone is demonstrating continuity in mineralization, potentially extending upwards of 1 km, with specific drill holes designed to test this trend [3][5]. Drilling Campaign Expansion - The 2025 drilling campaign has been expanded beyond the initial target of 12,000 metres, with expectations to continue drilling into November 2025, contingent on weather conditions [4]. - The company is employing a fence-based drilling approach to systematically expand the deposit and validate its geological model [3][4]. Technical Performance - The drilling contractors, including Dorado Drilling USA, have performed well, completing deep holes on schedule and achieving cost savings, with plans to enhance productivity with additional rigs [12].
Large Target Zone Confirmed at Aurania's Awacha Porphyry Copper Target
Newsfile· 2025-07-30 11:00
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]
New Inversion Data Reveals Six Anomalies at Aurania's Awacha Target
Newsfile· 2025-06-27 11:00
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].
