Depletion
Location, Access, Description
The Depletion property is located west of the Berry village (Abitibi, Qc), around 35 km northwest of Amos (Abitibi, Qc). The property consists of 22 claims totalling 1,133 Ha in both Guyenne and Berry townships (NTS 32D16). The claims are wholly owned by Globex and are not subject to any underlying royalties or third party interests. One can easily access to the property by road by taking the Lac Chicobi road and the 4 and 5 Range gravel road.
This area is characterized by low relief with elevations comprised between 300 and 330 meters above sea level. Most of the property is covered with Boreal type vegetation but numerous lots belong to private owners whose permission is required before applying for exploration permits.
Geology and Mineralization
The Depletion property is located in the Abitibi Archean Greenstone Belt, within the Superior Province of the Canadian Shield. Rocks of this area are composed of a bimodal series of felsic to mafic volcanics of Lac Arthur and Bearn Groups. An extensive EW trending sedimentary belt (Chicobi Belt) crosses the northern part of the region. The Archean Berry and Guyenne Batholiths are respectively located east and west of the Guyenne property.
All these rocks are oriented NW-SE and were verticalized and metamorphosed to the greenschists facies after successive tectonic events during Archean and Paleoproterozoic. Numerous mineralized occurrences are listed in the area of the property, including gold (Au), silver (Ag), zinc (Zn) and copper (Cu). Most of these showings are located along a NW thrust fault that crosses the entire Depletion property from northwest to southeast corners.
DDH CH87-07 intersected 1.7 g/t Au over 1.5m in auriferous quartz veins within a QFP dyke intruding the Lac Arthur felsic volcanics on the Depletion property (GM53452). An outcrop located around 80 meters southeast of CH87-07 is believed to correspond to the surface extension of that anomaly. Grab samples taken off that outcrop returned up to 3.73 g/t Au, 48 g/t Ag and 0.66% Cu (GM53452). Orogenic gold mineralization consisting of quartz ±tourmaline veins mineralized with 1 to 15% pyrite within ankeritized schists is known right to the NW of the Depletion property, grading up to 5.27 g/t Au / 3.00m and 4.91 g/t Au / 4.65m (CGL1, CGL2 and Golden Rock showings). A small VMS lense has also been defined by historical works within the Lac Arthur rhyolites less than 1km west of the Depletion property, grading up to 1.96% Zn / 7.5 m (CH88-09) and 1.34 g/t Au, 1.88% Zn / 4.0m (CH94-05).
History
Before the 80’s, SOQUEM conducted an I.P survey on the Depletion property followed by limited DDH (GM26013, GM27744).
During the late 80’s, Lake Minerals Ltd. undertook a large exploration program in the area of the property including data compilation, geological mapping, stripping, geophysics, lithogeochemistry, overburden drilling and diamond drilling (GM44008, GM45190, GM46767, GM48229). The CH87-07 gold showing (1.7 g/t Au over 1.5m) was discovered on the Depletion property by drilling an I.P anomaly associated with a geochemical anomaly in overburden. The Projet Chicobi synvolcanic fault system was also discovered during that drilling program.
During the early 90’s, Lake North America Ltd. conducted a thorough compilation then executed new geophysical surveys followed by DDH on the Projet Chicobi showing area (GM51201, GM53452). A magnetic and I.P survey was conducted southeast of the Depletion property (GM52901)
In 2020, Globex realised a surface compilation of historical data which highlighted several untested geophysical anomalies and numerous DDH intersections open laterally and/or at depth (GM72271).
Resources and Potential
No resource has ever been calculated on the Depletion property. Economic potential of the CH87-07 showing seems to be limited. The Lac Arthur felsic horizon though is a fertile unit for the exploration of volcanogenic sulfides mineralization as proven by the Projet Chicobi showing. Several I.P anomalies associated with EM axis in felsic volcanics are still untested by drilling in the south and west parts of the property.
