NLR News Release (August 31, 2026)
Northern Lights Completes Integrated 3D Geological Model at Horetzky
Copper Project, BC
Vancouver, BC – August 31, 2026 – Northern Lights Resources Corp. (CSE: NLR) (OTC:
NLRCF) (FSE: 0ZH0) (“Northern Lights” or the “Company”) is pleased to announce the
completion of a comprehensive geological model, the most advanced and integrated geological
interpretation ever completed at the Horetzky Copper Project in British Columbia’s Babine
Porphyry Belt. Modern inversion of the historical IP/resistivity data identified anomalies that were
not tested by the historical drill program. These results have been evaluated alongside the 2026
MobileMT data and the previously reported 3D aeromagnetic model, providing a stronger
technical basis for refining and prioritizing future exploration targets.
Highlights:
• The MobileMT AFMAG survey has confirmed the deep structure of the Horetzky
porphyry system. The MobileMT survey, comprising approximately 120 line-
kilometres, produced resistivity-depth sections that image the Project’s large-scale
subsurface resistivity architecture to more than 1,000 metres depth.
• Historical drilling, focused on near-surface targets and missed the strongest IP
response. Modern inversion now provides a more accurate picture of the location
and geometry of the strongest IP and resistivity responses.
• A 2km x 2.5km anomalous copper-in-soil area sits directly over the strongly
magnetic porphyry intrusion.
• Coincident geochemical & geophysical anomalies in a favourable geological
setting, with strong magnetic, IP, and resistivity features.
• The new results have been evaluated alongside the previously reported 3D
aeromagnetic model, which images a large, multi-phase intrusive complex
extending to more than 2,500 metres from surface.
Luka Capin, Interim CEO of Northern Lights, commented “This is the most important technical
milestone in Horetzky’s history. The integrated 3D model has fundamentally changed how we
understand the project, we believe we have one of the most compelling untested porphyry copper
targets in British Columbia. The big picture view of the plumbing system below the historic
drilling is beyond what we had originally envisioned, and it reinforces our conviction that Horetzky
1403-4395-2417, v. 1
has the potential to evolve into a much larger mineral system. We are more excited than ever to
accelerate our efforts to fully explore what this project can become.”
2026 Work Program:
The 2026 geophysical work comprised two principal components: modern 2D inversion of
historical IP/resistivity data acquired in 1972 by McPhar Geophysics on behalf of Hecla Operating
Company, and interpretation of the MobileMT survey completed by Expert Ge ophysics Limited
in May 2026.
The historical IP/resistivity results and the 2026 MobileMT data have been evaluated alongside
surface geochemistry, historical drilling and the previously reported 3D inversion of aeromagnetic
data collected by Precision GeoSurveys in 2021.
The main elements of the program include 2D inversion of historical IP/Resistivity data acquired
in 1972 on behalf of Hecla Operating Company. The reinterpretation of the historical IP/Resistivity
survey using Res2Dinv software has identified anomalies not previously drilled by Hecla, in
addition the re-flying the project area with state-of-the-art MobileMT airborne geophysics survey
by Expert Geophysics of Newmarket, Ontario. The datasets provide complementary information
at different depths. The historical IP/resistivity survey provides information on near -surface
responses to an estimated depth of approximately 100 metres, while the MobileMT data show
resistivity variations to more than 1,000 metres depth. The previously reported aeromagnetic
model images the interpreted intrusive complex to more than 2,500 metres from surface.
The inversion of the detailed aeromagnetic survey flown by Precision GeoSurveys for Volatus
Capital Corp in 2021 with the AFMAG inversion is now possible. The historic magnetic and recent
AFMAG datasets have been integrated into one 3D Inversion Model. Management believes that
the integration of advanced 3D modeling with deep- penetrating 3D geophysics will materially
reduce geological risk and sharpen drill targeting.
2D IP/Resistivity Inversion
A 1972 galvanic IP/resistivity survey by McPhar Geophysics for Hecla collected frequency-
domain data along NE -SW lines spaced ~150m apart, using a Dipole -Dipole electrode array.
Without modern inversion software available at the time , interpretation relied on pseudo- depth
sections, a method prone to distortion from the electrode array and topography, which can
1403-4395-2417, v. 1
misrepresent anomaly location and shape. Historical drill targets were selected from these raw
pseudosections combined with surface geochemistry.
The Company's 2026 re-inversion of this data, using Res2Dinv software (Loke and Barker, 1996),
has identified IP and resistivity targets not tested by the historical drill program. Effective
exploration depth is approximately 100m.
IP Section L2000S: DH73-4 did not optimally test high IP, anomalies at approximately 200W and 800W not drilled
MobileMT
MobileMT is a commercial AFMAG electromagnetic survey using natural audio-frequency fields
from distant lightning activity, offering deep penetration and adaptability to rugged terrain. Flown
in May 2026 along 200m -spaced east-west lines, the data w ere inverted (2.5D) into resistivity-
depth sections and integrated into a 3D VOXI model. As no physical property measurements have
been taken on-site, interpretation remains inferred.
Results of the inversion of the EM data are impressive, and clearly shows the macro scale
geological structure of the Horetzky intrusion and overlying lithocap to more tha n 1000m depth.
High resistivity responses generally indicate silica alteration or fresh rock, whereas low resistivity
responses indicate possible local concentration of mineralization.

Overview of the Horetzky Project
The Horetzky Copper Project covers 5,057 hectares in British Columbia’s Babine Porphyry Belt.
The Project has a five- year Multi -Year Area Based exploration permit authorizing exploration
activities including geophysical surveying, trenching and the drilling of up to 100 holes.
The Babine porphyry belt in an arc volcanic - and sedimentary belt which has been intruded by
Eocene age diorite to granodiorite porphyries. The Babine belt is well -endowed with porphyry-
style and related Cu -Ag and Mo mineralization, including the past -producing Bell and Granisle
copper mines, and advanced exploration projects including Nak operated by American Eagle Gold
Corp., (American Eagle) and the Duke district, operated by Amarc Resources Ltd. (Amarc).
The Horetzky project covers T he Mt. Horetzky Porphyry, which was first explored in 1965 by
Falconbridge using modern exploration methods. The Hecla Operating Company followed
Falconbridge, and drilled 8 diamond drill holes based on surface geochemistry and geophysics,
and encountered typical porphyry-style Cu mineralization. A series of small exploration
programmes was conducted by several operators (Rio Algom, CJL Enterprises, Volatus Capital)
with encouraging results.
