Great Atlantic Resources Provides Update on Drills of Massive Sulphides at Optioned Pilley's Island Project

Executive Summary

• HM Exploration Corp. provided an update on the first five drill holes (1,088m) of its maiden diamond drilling program at Great Atlantic's Pilley's Island Project in Newfoundland.
• Three of the five holes successfully intersected massive, semi-massive, and disseminated sulphide mineralization, confirming the targeted copper-bearing VMS-style debris flow geological model.
• Visual observations reveal angular chalcopyrite-bearing clasts and alteration zones consistent with proximity to a hydrothermal vent environment; laboratory assay results are currently pending.

Key Details

• Drilling Program Scope: First 5 holes completed for 1,088 metres, representing the initial phase of a planned minimum 2,500m maiden diamond drilling program.
• Hole PI-26-001: Intersected 5.82m (10.74–16.56m) and 6.27m (51.48–57.75m) of visual sulphide mineralization.
• Hole PI-26-002: Intersected 8.00m (10.00–18.00m) of visual sulphide mineralization.
• Hole PI-26-005: Intersected 4.00m (14.00–18.00m) and 6.98m (34.04–41.02m) of visual sulphide mineralization.
• Mineralization Characteristics: Intersections consist of massive, semi-massive, and disseminated sulphide mineralization, successfully confirming the targeted copper-bearing debris flow model.
• Geological Observations: Angular chalcopyrite-bearing clasts observed across multiple holes, indicating limited transport from source and proximity to a hydrothermal vent environment.
• Core Description: Mineralization is characterized by clast-dominated and matrix-dominated debris flows featuring sub-angular to angular fragments of massive sulphide (~85% of intercept) composed of chalcopyrite (Cpy) + pyrite (Py) ± sphalerite (Sph) ± galena (Gn), suspended in fine-grained disseminated sulphides and milled felsic/mafic rock.
• Project Geology & Context: Located within the Ordovician Roberts Arm Group (Notre Dame Subzone), sharing geological characteristics with historic Newfoundland VMS districts including the Buchans, Ming, and Rambler Mines. The property has a mining history dating to the late 1800s.
• QA/QC & Laboratory Protocols: Core samples submitted to Eastern Analytical Ltd. (ISO/IEC 17025 accredited). Analytical methods include ICP-OES (34-element), Au Fire Assay (30g) with AA finish, and Ore Grade Assay with AA finish. Standard QA/QC procedures (standards, blanks, duplicates) are applied.
• Assay Status: Laboratory assay results are pending; HM Exploration will release updates as drilling continues.

Notable Quotes

• Christopher R. Anderson, CEO of Great Atlantic Resources Corp.: "We are very pleased to see HM Exploration advancing the Pilley's Island Project with a disciplined and well-executed maiden drill program... We appreciate the technical work, commitment and professionalism that HM Exploration is bringing to the project, and we look forward to the receipt of assay results and further updates as exploration progresses."
• Nick Rodway, CEO of HM Exploration Corp.: "The goal of our first drill program is to test the VMS-style debris flow mineralization visible at surface... The angular nature of the mineralized clasts may indicate relatively limited transport from their source and is consistent with proximity to a hydrothermal vent environment."
