Hertz Energy Completes High-Resolution Airborne Magnetic And VLF-EM Survey Over Lake George Antimony-Tungsten-Gold Project

Hertz Energy Inc. has completed a high-resolution airborne magnetic and Very Low Frequency Electromagnetic (VLF-EM) survey over its 100%-owned Lake George Antimony-Tungsten-Gold Project in New Brunswick, Canada. The Tungmony Project comprises five mineral claims (4,392.4 hectares) surrounding the past-producing Lake George antimony mine on three sides over approximately 13 kilometers of prospective strike length. The survey was flown by Novatem Airborne Geophysics from June 21 to June 25, 2026, comprising 1,194 line-kilometers over 56.66 km² at 50-metre line spacing and an approximate 23-metre mean terrain clearance. Data was acquired using dual optically pumped magnetometers and a three-component VLF-EM receiver, providing substantially higher resolution than historical regional airborne geophysics datasets. The new airborne data is expected to greatly improve geological interpretation by identifying major structures, fault systems, buried intrusive bodies, and other geological features that may control antimony, tungsten, and gold mineralization at Lake George. This new data will also guide target generation for the Company's planned 2026 field program including prospecting and mapping, soil geochemistry, and induced polarization (IP) surveying, with up to 3,000 meters of diamond drilling planned contingent on the results of the field program. The historic Lake George Mine was North America's largest primary antimony producer, operating intermittently between 1876 and 1996. The airborne survey was completed by Novatem Airborne Geophysics between June 21 and June 25, 2026. The program covered a total area of 56.66 km² and consisted of 1,194 line-kilometres flown on 50-metre line spacing with 500-metre control lines. The helicopter flew at a median terrain clearance of approximately 23 metres, providing substantially detailed magnetic and electromagnetic data. The survey employed dual optically pumped magnetic sensors operating at 1,000 measurements per second together with a VLF-EM receiver measuring three orthogonal magnetic field components. This modern survey provides substantially higher resolution than historical regional datasets and will allow the Company to better define geological contacts, fault systems, structural breaks, and intrusive bodies that may host antimony, tungsten, and gold mineralization. The survey also provides a detailed geophysical framework across both the historic Lake George Mine and Hertz Energy's surrounding land package, highlighting several magnetic and structural features that extend onto the Company's claims and warrant additional exploration. Prospecting and mapping program will focus on known outcrop areas, as well as potentially favourable outcrop areas based on topographic and LiDAR surveys. This field work will include geological mapping, rock geochemistry, and a structural study. Soil geochemistry survey to evaluate the potential for blind antimony-tungsten mineralization by using dispersion of geochemical signals in surficial materials. The final sample selection sites will be based on local quaternary geology, satellite images, and LiDAR images. If quality exploration targets are developed from this preliminary work the Company envisions undertaking a program of ground IP surveying to firm up drill targets. Positive results would be potentially followed by up to 3,000 metres of diamond drilling later in the year. The Company's systematic exploration approach of combining geophysics, geochemistry, and drilling is designed to advance the project from target generation through discovery toward potential resource delineation and future development. The consolidated land position captures structural features interpreted to continue from the historic Lake George Mine, including a NE-trending fault, within what is understood to be a broader intrusion-related hydrothermal system hosting antimony, gold, tungsten, and molybdenum mineralization across the district. The Company believes these factors point to potential for the mineralized system to extend onto its claims, although this remains to be tested through exploration. Hertz Energy holds a total of five mineral claims comprising 577 claim cells and covering 4,392.4 hectares that surround the historic Lake George Mine on three sides. The claims were initially staked in September 2024 and April 2025 to secure prospective ground covering the contact between the Silurian Kingsclear Group metasedimentary rocks and the Devonian intrusive rocks of the Pokiok Plutonic Suite, the same geological setting that hosts the historic antimony mineralization. The Company's land package now covers approximately 13 kilometres of favourable strike length with multiple interpreted cross-cutting structures considered prospective for antimony, tungsten, and gold mineralization. Much of the property has seen little historical exploration despite favourable geology. While local outcrop provides excellent prospecting opportunities, large portions of the property are covered by thin glacial and lacustrine sediments that may conceal mineralization beneath shallow overburden. The completion of this high-resolution airborne survey marks an important step in advancing the Company's systematic exploration strategy. The new geophysical data will guide upcoming field programs designed to identify and prioritize high-quality exploration targets across the property.
