SKULL ISLAND PROJECT

Gold-Silver Epithermal System in Newfoundland

The Skull Island Project is a district-scale gold-silver system located on the Burin Peninsula, Newfoundland. The project combines historical resource scale, high-grade precious metal intervals, and strong geological and geophysical indicators of a coherent mineralized system.

SKULL ISLAND PROJECT

Project Overview

The Skull Island Project covers approximately 145 km² and consists of 580 mineral claims within the Avalonian Epithermal Belt. This geological setting is known for hosting gold-silver systems, including the past-producing Hope Brook gold mine.

Exploration completed to date includes over 100 drill holes, trenching, soil geochemistry, and both ground and airborne geophysical surveys. These programs have defined a large mineralized system with multiple zones and strong structural controls.

The project has evolved from an early-stage discovery into an advanced exploration asset, supported by a strong historical dataset and clear opportunities for expansion.

FLAGSHIP PROJECT

Eagle Zone

The Eagle Zone represents the most advanced area of the project, where drilling and geophysics define a coherent mineralized corridor. Historical work outlines approximately 1.08 million tonnes grading 2.19 g/t AuEq.

Mineralization extends over approximately 600 metres and remains open along strike and at depth. High-grade intervals occur within broader mineralized zones, indicating the presence of higher-grade shoots typical of epithermal systems.

SKULL ISLAND PROJECT

Geology & Mineralization

The project is interpreted as a low-sulphidation epithermal system characterized by structurally controlled mineralization hosted in volcanic rocks. Gold and silver occur within vein systems associated with faulting and hydrothermal alteration.

Geological observations include boiling-related textures such as adularia, colloform banding, and quartz after bladed calcite. These features are strong indicators of a productive epithermal environment.

High-grade silver mineralization is associated with silver sulfosalts, suggesting the potential for bonanza-style mineralization within the system.

Location & Infrastructure

The project is located in Newfoundland and Labrador, one of Canada’s most attractive mining jurisdictions. The property benefits from excellent road access and proximity to infrastructure, supporting efficient exploration and development.
