StrategX Intersects Multiple Sulphide-Rich Graphite Zones over 42.8 Metres, Confirming Critical Minerals Discovery at Nagvaak Project

Vancouver, British Columbia–(Newsfile Corp. – September 29, 2025) – StrategX Elements Corp. (CSE: STGX) (“StrategX” or the “Company“) is pleased to report the successful completion of its first diamond drill hole of the 2025 season at its 100%-owned Nagvaak Project, located on the Melville Peninsula in Nunavut. The drill hole intersected multiple sulphide-rich mineralized graphite zones over a 42.8-metre interval, significantly expanding the known mineralized footprint and validating the Company’s exploration thesis for a district-scale position.

Key Highlights:

• Drill hole NAG25-01 intersected four (4) distinct sulphide-rich mineralized graphite zones over a 42.8-metre interval.
• The hole targeted a high-priority geophysical anomaly and successfully intersected mineralization at the expected depth.
• The drilling intersected mineralized zones 580 metres west of historical drilling, confirming lateral continuity across the 6-kilometre mineralized corridor.
• Results validate StrategX’s Exploration Model, developed through ground magnetic and TDEM geophysical surveys, historical drill data, and surface sampling.
• The Nagvaak graphite-rich polymetallic mineralized corridor is 6,000 metres along strike and approximately 500 metres wide (see Figure 6), underscoring its scale and a potential Tier-1 critical minerals deposit discovery.
• Drill core samples have been submitted for laboratory analysis; assay results are pending.

2025 Drill Program

StrategX completed its 2025 summer drill program in August. The program successfully confirmed the exploration model for targeting future drill programs. The drill program also provided quality samples for further characterization of the high-purity jumbo flake graphite, along with critical metals identified in historical drill core (see press release March 7, 2023).

NAG25-01 intersected beds of meta-greywacke/’dirty’ arenites and interbedded arenite-mudstones. Sulphide banding was observed within these zones proximal to the sulphide-rich graphite horizons. Handheld magnetic susceptibility and conductivity readings confirmed the ground geophysical anomaly outlined by the Company and correlate strongly with the mineralization observed in the drill core (see Figure 1).

“This drill intercept validates our exploration model and highlights the scale potential of the Nagvaak mineralized system,” said Darren Bahrey, CEO of StrategX. “We are particularly encouraged by the width of the mineralization and the continuity of the graphite-rich zones, reinforcing Nagvaak Project’s potential to deliver a new Canadian source of critical minerals essential for the global energy transition supply chain.”

NAG25-01 intersected the mineralized graphite zones 580 metres west of historic drilling (see Figure 6). The 2025 program successfully confirmed that the exploration model outlined by ground geophysical, magnetic and TDEM surveys and further backed up by previous resampling of historical drill core and earlier surface sampling results. This mineralized corridor is outlined to be 6,000 metres along strike by approximately 500 metres wide, and it hosts significant volumes of high-grade, large flake graphite (see press release December 3, 2024).

Furthermore, StrategX previously identified polymetallic concentrations of critical metals, including nickel, vanadium, cobalt, molybdenum, zinc, copper, and precious metals (see press release March 21, 2024). With the successful completion of NAG25-01, StrategX is advancing toward defining a potential district-scale, multi-commodity critical minerals deposit in a new underexplored region of northern Canada.
