About IronOne Inc.

The assets of IronOne include the Lac Virot Iron Project located in Labrador and the Maguse River Iron Project located in Nunavut.

Lac Virot Iron Project

IronOne has an option to earn a 100% interest in the Lac Virot Iron Project, subject to a 2% net smelter return royalty. The Lac Virot Iron Project is comprised of approximately 114 square kilometres of map staked mineral licenses located in the southern Labrador Trough, Canada’s foremost iron ore mining region. Four major mines (Mont-Wright, Carol, Scully and Lac Bloom) are located within 20km of the project.

IronOne has completed a 2,271 line-kilometres airborne magnetic survey, as well as a reconnaissance mapping and surface sampling program on the project. The program was conducted to ground check historically mapped iron occurrences, as well as previously identified magnetic anomalies. Analytical results from thirty-three (33) grab and chip samples collected from exposed iron formation outcrops ranged from 16.57 to 60.5% Fe as Total Iron, with an average for all samples collected of 30.59% Fe. Exploration activities completed last year confirmed the presence of outcropping iron formation along three magnetic trends at Neal Lake, Emma Lake, and Sunday Lake which exhibit apparent strike lengths ranging from 1 km to over 5 kms.

This program was supervised by senior field geologists from MPH Consulting Limited, of Toronto, Ontario, who were contracted to provide exploration services to IronOne. The surface grab and chip samples described above were selective by nature and limited by the extent of outcrop exposure at the locality sampled. The resultant assay data may not be representative of the iron formation units occurring on the property.
