Introduction

Neoterrex has undertaken two comprehensive surface prospecting programs following the discovery of heavy rare earths (HREO) in the area during a 2023 government regional survey. NeoTerrex discovered syenite with rare earths mineralization outcropping at surface at several locations on the Revolver project with values ranging from to 12.87% TREO (Total Rare Earth Oxides)

Location and Infrastructure

The Revolver project is located 40 km northeast of the town of Saguenay, Quebec which is equipped with a deep-sea port and is fed by a main facility 735 kV hydroelectric power line. Mining development in the region is ongoing with Niobec’s world-class Niobium mine in operation since 1976, located 25 km northwest of Saguenay and First Phosphates proposed 10,000 t/y iron phosphate plant in the town of Saguenay.

The project is approximately a one-hour drive from Saguenay via highway 172. The property contains a network of gravel roads with smaller ATV trails that provide access to more remote portions of the project.

Geology

The property consists primarily of gneiss assemblages: fine- to medium-grained paragneiss, foliated and unbanded or sparsely banded, and a granular gneiss, strongly banded, which locally shows strong isoclinal folds. The vast majority of the numerous syenites and granitoids encountered are concordant with the the banding of the gneiss, but occasionally intersecting it. The intersecting syenites seem to be more interesting in terms of mineralization observed. These are mostly coarse to very coarse-grained, locally pegmatitic syenite, and appear to concentrate the bulk of REE mineralization. Carbonatite injections have been identified and, although they do not appear to contain mineralization, they are often sparingly associated with mineralization-bearing syenites. More work is necessary to determine the control of mineralization, however mineralized syenite appeared to be strongest in occurrences discordant to the regional north-northeast foliation.

Historical Work

A geological survey by the Ministère Bulletin géologique was conducted in the summer of 2023 with the aim of improving geologic knowledge and assessing mineral potential. This survey discovered the “Jalobert Sud-Est” showing, which sits within a section of claims encompassed by the Neoterrex claim block but not owned by Neoterrex. The showing contains 0.94% rare earth elements, with 0.38% Cerium and 0.26% Yttrium. It is also associated with pegmatitic intrusions. Prior to Neoterrex’s acquisition, the project had never been explored for its rare earths potential.

NeoTerrex Exploration and Results

NeoTerrex initiated exploration in 2024 for the project with a broad reconnaissance and prospecting program over the entire project resulting in the discovery of several mineral occurrences throughout the project area. Follow-up work was conducted in 2025 on the western portion of the project were dysprosium, a heavy rare earth, were higher. Best results for the project are listed in table below.

NeoTerrex has undertaken mineralogical and metallurgical test work to characterize the REE mineralization and assess processing potential. Planning is underway for the next phase of exploration, which will include targeted geophysical surveys, mechanical stripping, trenching, and initial drilling over the most prospective areas delineated in 2024–2025
