The Lindsay project was acquired by staking due to the presence of a large radiometric anomaly detected by a 2020 government regional survey. The anomaly is similar in strength and shape to well-known rare earths deposits like Kipawa and Niobec and currently unexplained due to the lack of any exploration work.

The property is located in the southern portion of the Abitibi-Temiscamingue region of the Province of Quebec, approximately 32 kilometres east-northeast from the town of Mattawa, Ontario. The property is accessible by gravel roads and small lodges are available in several locations nearby.

The property is located within The Grenville Geological Province, a vast geological region that spans portions of Southeastern Ontario and Southwestern Quebec in Canada, as well as parts of the Northeastern United States. This geological province is known to have significant mineral potential due to its diverse geological history and complex tectonic evolution. This province hosts a wide variety of mineral deposits, many of which have economic importance.

Historical work for the area is limited to a 1973 government regional mapping program which included stream sediment sampling.  Only six outcrops were identified on the property and were described as being gneiss or muscovite schist. The report (RP580) describes that the weak radioactivity within these schists was due to the presence of monazite, a primary rare earths mineral.

The regional survey also identified a coincidental major north by northeast fault crossing the property and beyond which warrants exploration, as it could explain the anomaly and could identify mineralization that may be associated with it.

In 2022, NeoTerrex conducted an airborne radiometric and magnetic survey over the property which allowed the company to further define the geophysical anomaly and local structural features. An initial surface reconnaissance work, consisting of prospecting and geological mapping, was initiated in August 2023.
