Des Herbiers - Uranium
Des Herbiers Township, Quebec (NTS 12L/07)

Updated November 2021

Property Description and Location
The Des Herbiers property consists of 66 non contiguous claims totaling 3,624.88 hectares (8,957.2 acres) located in NTS 12L/07, Des Herbiers township, approximately 9 km NW of the Baie-Johan-Beetz municipality and 52.5 km ENE of the municipality of Havre St-Pierre, North Shore area of northern Quebec (Figure 1). Access to the property is easy along highway 138 from Montreal to Natashquan and then travelling on tractor roads. Topography is comprised of flat lying areas with bogs and low-lying hills.

The claims are wholly owned by Globex Mining Enterprises Inc. and are not subject to any underlying royalty or any third-party agreements.

History
Exploration on the Des Herbiers property dates back to 1952, when Gérald E. Cooper mapped the Des Herbiers township area for the Ministry of Mines of the Province of Québec (RP 286). He then detailed the geology of the same area in 1957 (RG 074).

The discovery of uraninite and pitchblende in pegmatites of the Turgeon Lake Intrusive Complex (now labelled Suite felsique de La Galissonnière) in 1967 precipitated a major staking rush by a large number of junior companies.

The first exploration work performed on the present property, was conducted in 1967, when Grandroy Mines Ltd drilled 19 holes for a total of 1,431 meters. The drill holes are located within the northeastern bloc of the property (Grandroy Zone – Figure 2). The best results from that drilling returned 0.5% U3O8 over a core length of 1.19 m (GM-22973). That same year, a consortium of nine companies executed an airborne radiometric survey covering the three northern most blocs of claims (claims 1 through 7 on figure 1). Still in 1967, Gulf Uranium Mines Ltd. along with St-Pierre Uranium Mines Ltd. conducted an airborne magnetic and radiometric survey covering the southern portion of the present property (main bloc of claims). Table 1 summarizes the exploration work done on or near the Des Herbiers Property.

Geological setting

Regional geology
The Des Herbiers Property is located in the Grenville Province of the Canadian Shield. The Grenville features complex, irregular folded structures, numerous gneiss domes and basins and variable intrusive rocks ranging from gabbro to alkali-rich rocks. The rocks underlying the immediate area of the property are comprised of biotite rich granitic rocks (Suite felsique de La Galissonnière), quartzites and quartzo-feldspathic gneisses that are derived from strongly metamorphosed sandstones and arkoses (Wackeham Group), amphibole rich (ouralite) gabbros and gneisses (Suite mafique de la Robe-Noire). Regional structures trend north to northwest, and display large-scale curvilinear folding (Figure 3).

Property geology
Rocks of the Des Herbiers property are almost exclusively comprised of biotite granite pertaining to the Suite felsique de La Galissonnière (Figure 3).

Mineralisation
The Des Herbiers Property area is underlain by geological units susceptible to contain significant uranium mineralization of economic interest, including uranium veins and disseminations linked to pegmatites, granitic gneisses and in meta-sedimentary rocks, which are mineralized in uranium and rare earth elements, as well as porphyritic granitoids carrying copper-gold and copper-molybdenum mineralization. The geological evidence points to both the Rössing (Namibia) and Olympic Dam (Australia) uranium models.


Mineralisation was noted as occurring predominantly in the pegmatites and granites bodies, often along the contacts between these units. Gneisses are generally noted as unmineralized bodies. Uncertainty in the results is related to the fact that all sampling was surface grab and channel sampling. By its nature, it is uncertain if the surface results are reflective of subsurface results. Potential exists for surface depletion or enrichment of various elements. Uranium is known to be a mobile element, and can variously be enriched or depleted, depending on the chemistry and ground water characteristics of the area. Considering the results between the channel sampling (Table 9) and the ones obtained from drilling (Tables 2 through 8), one can notice that the channel samples are generally of higher grade than the drill samples.

Conclusion
The exploration work conducted by Uracan Resources Ltd and the previous work done by namely Denison Mines and other companies has defined several priority targets within the Des Herbiers Property, as shown by the large number (17) of uranium occurrences (Figure 4). Several airborne and ground geophysical surveys were carried out on the property. These surveys consisted of magnetic and radiometric surveys. Following this work, 403 diamond drill holes were bored, totalling 57,663.4 meters of core. Recovery from the drilling is excellent, averaging well over 90%.

The field and geophysical observations suggest that the 225-km2 Suite felsique de La Galissonnière (formerly labelled the Turgeon Lake Intrusive Complex) remains the priority target. The focus should be on the: Lac Petit; Double S; Lac Turgeon and Lac Tanguay areas. These areas have outlined several airborne radiometric and ground scintillometer anomalous readings, along with uranium mineralization from grab-channel samples and drilling.

The Des Herbiers Property holds an excellent potential to further develop the known mineralized zones, as well as to discover new mineralization. The area is underlain by geological units susceptible to contain significant uranium mineralization of economic interest, including uranium veins and disseminations linked to pegmatites, granitic gneisses and in meta-sedimentary rocks, which are mineralized in uranium and rare earth elements, as well as porphyritic granitoids carrying copper-gold and copper-molybdenum mineralization. The geological evidence points to both the Rössing (Namibia) and Olympic Dam (Australia) mines.
