Lewis Pilley's Project
Overview
The Lewis Pilley's Project hosts high-grade VMS mineralization with a rich mining history and strong exploration potential
2026 Drilling at the Clifford Jones Zone
Phase One drilling confirmed a multi-lens polymetallic system at Clifford Jones
HM’s 2026 Phase One drilling program was designed to evaluate the continuity and geometry of mineralization beneath known surface occurrences at the Clifford Jones Zone.
The program confirmed significant copper-zinc-silver-gold mineralization within both an upper and lower sulphide lens. The upper lens has been confirmed over a strike length of ~145 metres and the lower lens over ~40 metres.
Both mineralized horizons remain open along strike and down dip, providing targets for continued exploration.

Geology and Mineralization
Geology
- Lewis Pilley’s is located within the Notre Dame Subzone of the Dunnage Tectonostratigraphic Zone
- Most of the Project is underlain by Ordovician submarine volcanic rocks of the Roberts Arm Group which is regionally identified as part of a mature arc sequence referred to as the Buchans-Roberts Arm Belt that also hosts the historic Buchan’s mine.
- Mineralization occurs as low grade (Spencer’s Dock); medium grade (Old Mines); and high grade (3B-Zone/Clifford Jones).
- The deposits that are of both sub-seafloor replacement and exhalative varieties. The deposits are often flanked by extensive chlorite, sericite, silica, K-feldspar and epidote alteration often observed in bimodal-felsic VMS systems.
The Spencer’s Dock area displays sericite/silica alteration that generally increases in intensity near mineralized zones, while the 3B / Old Mine areas display sericite/silica alteration that is abundant but less widespread and is more intense when proximal to mineralized zones.
Mineralization
From north to south this Project is underlain by:
- Lushes Bight Group – Lower OrdovicianComposed of pillow basalts, pillow breccias, aquagene tuffs, massive basalt flows, flow breccias, and chlorite schist.
- Springdale Group – SilurianTerrestrial sequence of volcanics, pyroclastics, epiclastic to volcaniclastic sediments.
- Roberts Arm Group – Middle OrdovicianThe Roberts Arm Group, which hosts known mineralization, is complexly faulted and consists of an older tholeiitic terrane overlain by more calc-alkaline thrust slices. It is suggested that it represents an evolution from tholeiitic, back-arc basalts to calc-alkaline intermediate to felsic volcanics deposited at about the time of continental collision in a neritic to littoral environment.

Why VMS (Volcanogenic Massive Sulphide)?
VMS Deposits are Polymetallic, High-grade and Understood Geologically
Polymetallic Revenue Streams
• Copper, zinc, lead, gold, silver (± cobalt) in a single asset
• Diversified exposures reduces reliance on a single commodity and provides a natural hedge against price volatility
High Grades & Strong Economics
• VMS deposits are known for compact footprints with robust grades in copper/zinc
• By-products (gold/silver) lower effective cash costs
Geological Predictability & Camp Scale
• Well-understood geological model; exploration is de-risked
• VMS deposits occur in clusters - one discovery often leads to several
Strategic Alignment
• Supplies critical metals for electrification (copper, zinc, cobalt)
• Governments and majors increasingly prioritizing securing supply, VMS systems are
a priority given multiple commodities present
M&A & Exit Potential
• Juniors advance discoveries, natural acquisition targets for mid-tiers/majors
• Track record of premium takeouts in established VMS camps (Noranda, Kidd Creek, Flin Flon, Iberian Pyrite Belt)
