Northern Lights Resources Reports Positive 3D Inversion Modelling Results for Horetzky Copper Project
Vancouver, BC – June 11, 2026 – Leads & Copy – Northern Lights Resources Corp. (CSE: NLR) (OTC: NLRCF) (FSE: 0ZH0) has reported positive results from 3D inversion modelling of aeromagnetic survey data for its Mt Horetzky copper porphyry intrusion, part of the Horetzky Copper Project in British Columbia’s Babine Porphyry Belt. The findings support the company’s porphyry-style copper exploration model and aid in refining targets.
The 3D inversion provides a detailed model of the deep structure of the Mt. Horetzky intrusive complex. When combined with historical surface geochemistry, radiometrics, and digital elevation model data, these results reinforce the company’s exploration strategy. The Horetzky Copper Project, located in north-central BC, features Eocene intrusive stocks and dykes intruding Triassic to Early Cretaceous host rocks, with exploration focused on porphyry-style copper, molybdenum, gold, and silver mineralization.
The project encompasses 11 mineral claims covering 5057.29 hectares, with Northern Lights holding an exclusive earn-in option. The claims have assessment reports valid until December 22, 2028. The Babine Porphyry Belt has a history of copper mining, including the past-producing Bell and Granisle mines, and significant occurrences like Morrison, Hearne Hill, and Duke. The Horetzky project shares characteristics with established porphyry deposit models, such as the neighbouring NAK deposit operated by American Eagle Gold.
Initial exploration of Horetzky in the early 1900s focused on silver associated with base metal veins. Porphyry-style exploration resumed in the 1960s, leading to the discovery of the Bell and Granisle deposits. Subsequent exploration by various operators included soil and rock sampling, geophysical surveys, and a limited diamond drill program by Hecla Mining in 1973. Drill core analyses revealed widespread copper mineralization spatially coincident with the central porphyry intrusion.
The regional geology of the Babine Porphyry Belt is influenced by multiple tectonic events, including collisions, contraction, and crustal extension, resulting in varied geological structures and elevations. Copper mineralization in the belt is primarily linked to Babine Intrusions, composed of small plugs and dykes of porphyry and granodioritic rocks dated to the early Eocene. These intrusions are considered the subvolcanic roots of a calc-alkaline magmatic arc.
Project geology at Mt Horetzky is largely inferred due to sparse outcrop and significant overburden. The area is underlain by a diorite stock with later porphyry dykes. Pyrite, chalcopyrite, and molybdenite are present as disseminations and fracture fillings, with native copper and chalcocite also noted. The diorite shows weak chlorite alteration, while dykes exhibit localized clay and quartz-sericite alteration. Dykes and jointing typically trend northwest or northeast.
Historical surface geochemical sampling has identified an anomalous copper area of approximately 2×2.4 km, correlating with a strongly magnetic porphyry intrusive body. The CJL showing, discovered in 2014, yielded assays exceeding 1% copper and 277.7 ppb gold, indicating high-grade potential within the mineral system. Surface sampling has not fully covered the intrusive, suggesting potential for mineralization extension to the south and west.
A 1972 IP/Resistivity survey over the Mt Horetzky porphyry intrusion encountered historical drilling challenges due to data inversion limitations. However, recent interpretation of digital elevation models and radiometrics, including high potassium correlation over the core intrusive area, further supports the porphyry style mineralization model. Airborne magnetics surveys have consistently identified a strong magnetic signature for the Horetzky intrusive.
The 3D Voxel model reveals multiple intrusive phases, with the latest phase exhibiting stronger magnetic susceptibility. Radial dykes are present at shallow depths, and the intrusive root extends to over 2500 meters from the surface. Key findings supporting the exploration model include the strong magnetic signature of the porphyry intrusion, its depth extension, differentiation of intrusive phases, and the link between copper mineralization and intrusive-host rock contacts.
