Lac Marian Uranium

Property Overview

The Lac Marion Uranium Property consists of 49 mineral claims, totaling approximately 2,759.80 hectares, situated on NTS sheets 31J14 and 31J15, near Mont Laurier in southwestern Québec. The property is about 65 km northeast of Mont Laurier and approximately 250 km north-northeast of Ottawa, Ontario. Accessible via paved and gravel roads (routes QC 309N or 311N), the property can be reached by four-wheel drive vehicles and ATVs for field exploration.

Property Geology and Mineralization

The property lies within the Grenville Structural Province, specifically the Central Metasedimentary Belt (CMB), which is divided into several tectonic terranes. The claims are underlain by lithologies of the Baker Domain, a sub-domain of the Mont Laurier terrain, featuring complexly deformed metamorphic rocks such as quartzite, calc-silicates, marble, paragneiss, and pegmatites. Metamorphic pegmatites are a key host for uranium mineralization, with uraninite, uranothorite, and secondary uranophane identified in previous exploration.

The Mont Laurier Uranium Exploration Camp area is one of many radioactive districts scattered throughout the Grenville Structure Province. The many of the Grenville radioactive occurrences (chiefly related to intrusives of granitic composition) are found in the southwestern extent of the structural province, extending from southwest Quebec into eastern Ontario. The mineralization described in various showings located on the Property is summarized below.

Key historical uranium occurrences include:

1. JRB-4 Effiat Lake and Pond Zone: Discovered in the 1970s, uranium-bearing pegmatitic bands show grades of 0.076% to 0.48% U₃O₈. The 2024 work relocated the Pond Zone, recording scintillometer readings of 5,000 cps to 13,500 cps.
2. JRB-4 New: Discovered in 1975, this zone is hosted in pegmatite and biotite-rich shale. Historical uranium grades ranged from 0.029% to 0.18% U₃O₈, with scintillometer readings in 2024 reaching 10,000 cps to 57,000 cps.
3. Lac Lafargue: A 14-meter-long pegmatite band discovered in 1975, with uranium grades of 0.73% to 1.14% U₃O₈. The 2024 fieldwork confirmed high scintillometer readings between 12,000 and 23,000 cps.
4. Marielle Lake: Discovered in 2004, uranium mineralization is associated with coarse-grained pegmatites, with scintillometer readings from 4,000 cps to 34,000 cps recorded during the 2024 program.
5. Lac Marion: Discovered in 1968, uranium-bearing pegmatites returned grades up to 0.63% U₃O₈ in historical samples. During the 2024 exploration, a nearby outcrop showed scintillometer readings of 700 cps to 3,700 cps.

Exploration

During the 2024 exploration program, Linear Minerals completed geological mapping, prospecting, sampling, and a scintillometer survey. A total of 28 rock samples were collected, along with 70 scintillometer readings across the property. The Lac Marion Uranium Property shows potential for further discoveries of uranium and thorium mineralization, with favorable geology, historical drill data, and surface outcrop findings. Its excellent road access and proximity to exploration services make it a promising target for ongoing exploration.
