The Nemegosenda Project
// Property Background
The Nemegosenda Property (the “Property”) hosts a disseminated-type niobium deposit within approximately 3,478 hectares on the Chewett-Collins township boundary, 30km northeast of Chapleau, Ontario. With the inclusion of over 750 hectares of grandfathered patented claims (e.g. established before the 1985 Patent Act) over primary mineral zones, advanced exploration work can be initiated with lower regulatory hurdles. First documented for it's unusual red syenite in the 18th century, the Property was first explored in the early 1950s by Dominion Gulf Company, an exploration arm of Gulf Oil, and has been extensively delineated over the course of further decades of exploration.
The Nemegosenda Complex is an uncommonly large carbonatite intrusion isolated within an igneous province of gabbroic anorthosite. The containment of this magmatic intrusion is reflected by the large scale, indications of significant high pressure somatization and brecciation, as well as the extensive fenitization zone. These near-surface niobium-hosted zones offer several additional unique targets easily accessible on-site for further exploration.
// Mineral Estimates & Ongoing Exploration
In 1956, Dominion Gulf initially estimated that the D Zone within the Nemegosenda Property contained 20,000,000 t (imperial tons) grading 0.47% Nb2O5. This is an “historic” non-NI 43-101 compliant resource as this estimate predates existing regulatory standards. Using additional drilling performed by Niostar, in 2009, an updated resource estimate of 45,000,000mt (metric tonnes) at a grade of 0.43% Nb2O5 within the D Zone was calculated (again, non-43-101 compliant). Also at this time, a preliminary exploration target of 110,000,000mt at 0.35% Nb2O5 for the SE Zone was produced.
An additional zone of of interest, the CML Zone, is essentially unexplored due to thicker glacial sediment cover. As a preliminary investigation, NioShield has recently performed an MMI orientation soil survey over the target with assay results. In addition, four other geophysical anomalies, similar to those that host known mineralized zones have been identified for preliminary drill testing in 2025.
At various points of exploration, insight into the viability of mining and on-site processing has been investigated at great length. Reports on the property have been completed by Colorado School of Mines Research Foundation Inc. in 1961, by Dominion Gulf in 1988, SGS in 2009, as well as further research efforts from several other companies over the years. Dates of significant research on exploration, drilling, metallurgy and processing have occurred during the periods of 1956, 1988, 1999, 2009, 2014, and 2024. We highly regard and honor all of the work that has occurred over the years at the Property.
