The Resource
Vault

Nearly five decades of exploration have consistently demonstrated high-purity silica mineralization across the Citadel property. The Mount Wilson Formation quartzite hosts some of western Canada's premier industrial silica resources.

Columbia Valley infrastructure with highway and rail corridor

Investment Thesis

A strategic industrial minerals opportunity distinguished by exceptional geological validation, infrastructure, and exposure to structural growth markets.

Tier-One Jurisdiction

British Columbia, Canada — one of the world's premier mining jurisdictions with mature legislation, secure tenure, and transparent permitting.

District-Scale Position

32,300 hectares controlling nearly the entire prospective Mount Wilson Formation quartzite trend across approximately 90 km of strike.

Proven Purity

Five decades of independent exploration campaigns consistently confirming 98.5–99.9% SiO₂ purity across multiple zones.

Adjacent Producers

Immediately adjacent to the producing Mount Moberly Silica Mine and the permitted Sinova Quartz Project (>99.6% SiO₂).

Exceptional Infrastructure

Direct Trans-Canada Highway and Canadian Pacific rail access. Proximity to Golden, BC with electrical grid and skilled workforce.

Simple Mining Concept

Open quarry extraction with crushing and off-site processing. No flotation, no cyanide, no conventional tailings impoundment required.

Exploration History

Nearly five decades of systematic exploration confirming consistent high-purity silica mineralization.

1975

Initial regional sampling. Samples returned up to 99.64% SiO₂.

1977

Regional mapping, systematic sampling, and one drill hole intersecting 152–153 m continuous quartzite from surface.

2014

Bulk sampling, metallurgical testing, frac sand testing. Average silica grade 98.6% SiO₂.

2017

51 systematic rock samples across ZIM Zone. Average grade 98.76% SiO₂.

2023

27 surface samples at Moberly East Zone. Average grade 98.94% SiO₂. Confirmation of historical interpretations.

Structural
Demand

Unlike precious metals driven by macroeconomic cycles, high-purity silica demand is propelled by long-term structural industrial growth across multiple sectors.

Solar Energy

Photovoltaic glass manufacturing requires ultra-high purity silica for panels and silicon production.

Semiconductors

Global semiconductor fabrication continues to expand, driving demand for ultra-high purity quartz.

Specialty Glass

Optical glass, low-iron glass, and technical glass applications demanding consistent purity.

Engineered Stone

Premium countertops and architectural surfaces requiring high-grade crystalline silica aggregate.

Advanced Materials

Silicon carbide, specialty ceramics, and advanced composites for industrial applications.

Foundry & Construction

Metallurgical-grade silica for foundry casting, high-performance concrete, and industrial abrasives.

Pristine British Columbia Rocky Mountain wilderness

Responsible Development

Citadel's proposed quarry development model significantly reduces environmental complexity compared to conventional hard-rock mining operations.

Simple Quarry Operation

Open quarry extraction with primary crushing — no flotation circuits, no cyanide processing, no conventional tailings impoundment.

Low Water Demand

Minimal process water requirements compared to conventional metallic mining. No wastewater treatment facilities anticipated on-site.

Reduced Carbon Profile

Absence of energy-intensive milling circuits, limited on-site processing, and proximity to existing infrastructure reduce the overall carbon footprint.

Community & Indigenous Engagement

Located within an established mining district with decades of industry familiarity. Committed to meaningful engagement with Indigenous Nations and local communities.
