Critical One Energy Inc.
Howells Lake Antimony Gold Project
The project is located in Ontario’s prolific Thunder Bay Mining Division, representing one of the largest and most significant antimony-gold assets in North America.
Overview
The Howells Lake Antimony Gold Project represents a pivotal advancement in critical minerals exploration within Ontario’s Thunder Bay Mining Division, offering substantial geological potential and economic promise.
Spanning 13,990.90 hectares across 697 claims, the project is one of Ontario’s largest and most significant antimony-gold asset, strategically positioned to address global supply gaps in these critical minerals.
A historic mineral resource estimate reported 1.7 million tons grading 1.7% antimony, equivalent to approximately 51 million pounds of contained antimony (non-NI 43-101 compliant). Additionally, gold mineralization has been documented, with grades reaching up to 2.3 ounces per ton.
Building on decades of underexplored potential, Critical One Energy aims to capitalize on the project’s 20 kilometers of favorable geology, which remains largely untapped. Bruce Durham, renowned for drilling the discovery hole at the Hemlo Gold Deposit, brings his exceptional expertise to unlock the full potential of Howells Lake. The inclusion of Howells Lake amplifies Madison’s portfolio and positions the company favorably in this critical minerals space.

Antimony and Gold Exploration
Project Highlights
- Historic Resource Estimate:
• 1.7 million tons grading 1.7% antimony, equivalent to approximately 51 million pounds of contained antimony (non-NI 43-101 compliant).
• Gold mineralization reported up to 2.3 ounces per ton.
High-Grade Mineralization:
•Mineralization extends from surface to 0 meters depth.
• Remains open laterally and at depth. •
Favorable Geological Setting:
• Shares similarities with the legendary Hemlo Gold Deposit (25+ million ounces of gold).
• Features deformation zones, quartz-sericite alteration, green mica, and felsic dikes, indicative of high potential mineralization.
Strategic Market Position:
• Antimony designated a critical mineral by Canada, the United States, and the European Union.
• Global supply disrupted by China’s export restrictions in 2024.
Key Benefits & Opportunities
- Economic Potential:
• The combination of soaring gold prices (over $2,600 per ounce) and antimony prices (above $16 per pound) enhances the project’s value.
Underexplored Land:
• Only 3 drill holes in the northwestern trend of the project area, offering substantial potential for new discoveries.
• Historic exploration spending exceeded $2 million in the 1970s and 1980s.
Strategic Scale:
• Covers over 20 kilometers of favorable geology, with high-grade stibnite (antimony mineral) reported over 5 kilometers.
Antimony:
A Critical Mineral
Antimony’s unique properties make it indispensable in:
Bullet hardening, shell casings, and high-tech military screens.
Fire retardants, semiconductors, and solar panel manufacturing.
With China producing 48% of global supply but ceasing exports in September 2024, new sources like Howells Lake are critical to stabilizing Western markets.
