The summer season drilling program was once designed to seek for extensions to the Lion Zone, in particular ill plunge from recognized mineralization, and to infill drill at the Lion reserve to outline the zone geometry to a self belief stage that may permit a life mineral useful resource estimate to be performed to an Indicated Useful resource classification.

Lion Useful resource Drilling (Desk 1, Determine 1)
Drilling has effectively outlined mineralization extending down-plunge one of the crucial high-grade shoots which might be inner to the Lion zone for life MRE modelling. Drilling reported right here intersected mineralization under the central high-grade zone of Lion, together with Prime-grade sulphide intersections of four.40m @ 14.34% CuEqRec¹ in gap PML-25-029b integrated inside of 20.40m of three.58% CuEqRec¹), and 1.59m @ 27.92% CuEqRec¹ in gap PML-25-025, integrated in 19.8m of two.71% CuEqRec¹). Extensional intersection at the west facet of Lion integrated 2.65m @ 17.79% CuEqRec¹ in gap PML-25-31 integrated inside of 8.10m of seven.13% CuEqRec¹). Those holes have in large part showed the grade of the Lion zone in addition to expanding the scale of the interpreted lofty grade lodes.

¹Copper Similar Rec Calculation (CuEqRec¹)
CuEqRec represents CuEq calculated in accordance with refer to steel costs (USD): 2,360.15 $/oz. Au, 27.98 $/oz. Ag, 1,215.00 $/oz. Pd, 1000.00 $/oz. Pt, 4.00 $/lb Cu, 10.00 $/lb Ni and 22.50 $/lb Co., and a fix grade of 80% for all commodities, in line with similar friends.

Terry Lynch, CEO of Energy Steel states “another good round of results showing very solid increases in the known mineralized area in the Lion Zone. At the moment even as we continue to test the extension of Lion and grow its mineralized area we have three strategic target areas supported by geology and borehole EM that look promising to deliver our next big breakthrough. Hole 64 which we talk about below and the very promising large off hole anomaly that sits in our interpreted fold hinge will be targeted by a series of holes as soon as drilling commences in 2026. This delay is to enable the heavier land rigs to be mobilized for this deep drill target. Tiger Deep the anomaly we discussed in our last release is being targeted prior to the Christmas break as are initial holes on the Hydro Lands.

Our integrated geophysical and geochemical toolkit has delivered for us in the past, and our exploration team has never been more optimistic than it is today. We are well funded for our 2025–2026 work programs and have announced our plan to list on the NYSE to access deeper U.S. capital markets. As we move into the upcoming winter and summer 2026 drill campaigns across the district, we’ve asked the team to systematically pursue the highest–priority targets, and while we haven’t yet defined a second Lion or Nisk–style zone, we believe this is one of the most target–rich exploration opportunities over the next 12 months.”

Nisk East Drilling (Desk 1)
Drilling on the Nisk East goal contains holes PMN-25-005 via PMN-25-011. Little intersections of Ni-Cu-Pd mineralization was once intersected in holes PMN-25-005, 008 and 011, together with 4.00m of two.34% CuEqRec¹ in gap PMN-25-005. The Nisk East department is now being re-assessed with the hot land acquisition to the west (see information drop November 4, 2025) which now permits Energy Steel to successfully goal the extension of the geology that hosts this Ni-Cu device (Determine 2) and is on accident with the Lion and just lately intersected Lion West zone (assays pending).

Energy Steel has additionally gained assay effects from the primary 7 holes at the fresh Li-FT acquisition (PMX-25-001 via PMX-25-007). All holes had been concentrated on airborne EM anomalies, and all holes intersected semi-massive to larger sulphides explaining the EM conductors. Incorrect important steel values had been intersected. These days the PMX program is specializing in the just lately received ‘Hydro Lands’ which is interpreted to be the folded extension of the Nisk-Lion device (see information drop November 4, 2025). Drill allows have now been granted for this department permitting drilling to start in this impressive goal department.

Lion-Tiger Deep Goal
‘Deep Tiger’ is a goal this is in accordance with reinterpretation of earlier Tiger drilling that means Tiger is made up of ‘rip-up’ blocks of larger Ni-Cu sulphides carried in a tonalitic intrusion from a deeper greater reserve (Determine 3). That is supported by way of the truth that Tiger larger sulphides are hosted in a past due tonalitic intrusion, and that fresh floor mapping within the department came upon alike ‘rip-up’ blocks in outcrop (Determine 4) of each larger sulphides, and ultra-mafic in tonalite intrusions. The use of numerous vectoring tactics Energy Steel believes it’s directing exploration proximal to the supply of this mineralization.

As reported on November 4, 2025, 3 holes (PML-25-021, 026a, 030) had been drilled under the intensity answer of the hot 2025 airborne VTEM survey finished by way of Energy Steel. Those holes had been trying out the department between Lion and Tiger to intersect the mineralized horizon and serve drill holes for BHEM surveys.

As prior to now reported gap PML-25-026, drilled closest to Lion returned incorrect important assays, week the BHEM survey off-hole conductors had been pointing to the presence of the Lion reserve. Hollow PML-25-021 intersected Lion taste mineralization (3.70m @ 1.48% CuEqRec¹) and indicated an off-hole anomaly (Determine 2) east of the Lion reserve. Next drilling of this BHEM off-hole goal (PML-25-038) intersected extra Lion taste mineralization (assays pending) and BHEM surveys are these days being performed in this gap.

Essentially the most easterly gap, PML-25-030 (assays pending) didn’t intersect important eye mineralization, however the BHEM survey produced a massive, most likely thick bodied anomaly deeper and to the east of the opening. This BHEM panel was once examined by way of gap PML-25-035 (assays pending), which intersected sulphide mineralization in ultra-mafic host rock. This higher delicate the off-hole BHEM anomalies (Determine 2) which might be these days being examined with drilling.

Lion-Tiger Deep Goal – Hollow PN-24-064
All through drilling in 2024 at the Lion reserve, one gap, PN-24-064 was once prolonged way past the Lion Zone and the opening ended at 1046 meters. Next BHEM surveys indicated an overly massive off-hole anomaly, however the complete anomaly couldn’t be modelled because the conductor was once under and in entrance of the tip of the opening. This gap was once due to this fact prolonged 300 meters (finish at 1347 meters) and resurveyed with BHEM. This has resulted within the greatest off-hole conductor to hour at the challenge.

This conductor stretches in entrance of the mineralization and conductors advanced in holes PML-25-021, 030, 035 and 038 (Determine 1). It sits on each our fresh Nisk lands and the Li-FT acquisition claims which Energy Steel personal 100% (Determine 2). The BHEM panel is on accident with the newly received ‘Hydro Lands’. It happens within the interpreted location of a line hinge which has advanced into a concern goal department for Energy Steel to seek out extra Cu-Ni mineralization.

The positioning of the ambiguity, its massive dimension, its proximity to subsidiary BHEM anomalies, and indications of mineralization (Holes PML-25-021, 035, and 038) are all sure supporting proof for advancing this goal. Energy Steel is these days assessing the logistically choices for drilling into this anomaly, with the extension of PML-25-021, that sits at roughly 700m intensity already, as a major candidate for extension and trying out of the BHEM panel. Energy Steel will replace this goal’s development within the coming weeks.
