BONFORTEL PROPERTY (CU, ZN, AU, AG)
Location:
135 km north of Amos (Abitibi, Quebec) in the Poirier Township.
Access: Accessible by road in all seasons
Land: 14 mining claims covering 389 ha. The property is located to the southwest of Poirier Mine, a former copper producing mine, and is adjacent to the west of Cancor’s Kistabiche and Poirier properties.
Interests:
Cancor has a 100% controlling interest subject to a 2% net smelter return royalty in favour of Teck Cominco.
Previous Work:
Between 1960 and 1990 mining exploration companies such as Rio Tinto and Noranda drilled 15 holes as well as conducted ground magnetic, electromagnetic and IP-resistivity surveys. Aur Resources (“Aur”) acquired the property in April 1991 and carried out exploration work comprising geological surveys, trenching, IP/Resistivity and magnetic surveys as well as drilling 25 holes totalling 7218 meters.
Cancor acquired the property in 2004 and has carried out exploration work on the entire property using magnetic, gravimetric, InfiniTEM® and Titan-24 surveys. The company has also drilled five new holes totalling 3843 meters.
Geology:
The Bonfortel property is entirely underlain by felsic volcanic rocks in the Joutel Volcanic Complex, east of the Mistaouac tonalitic pluton in the Archean greenstone belt of the Abitibi Subprovince. These felsic rocks belong mainly to the Poirier Member of the Joutel Formation of the Joutel-Raymond Group. Pillow mafic volcanites of the Vanier-Dalet-Poirier Group overlie them to the South East. Gabbro masses, sills and dykes of variable dimensions intrude them.
Structurally, the felsic volcanites appear to be grouped within a caldera measuring 4 to 5 kilometres in diameter and crossed by an orthogonal network of synvolcanic faults trending NE-SW and NW-SE. The polymetallic massive sulphide deposits belonging to the Poirier Mines, Joutel Copper, and Explo-Zinc are all located on the rim of this caldera as well as the Fourth Corner prospects (zinc-rich massive sulphides) discovered by Aur in the south part of the property.
Results:
Hole BON–05-01 and its wedge BON-05-01A intersected at depth between 906.6 meters and 1,187.8 meters in the volcanic felsic horizon hosting the south-eastern extension of the South zone of the Poirier Mine. Up to 15% disseminated pyrite with subordinate amounts of sphalerite and chalcopyrite are present in several metric intervals. The best results were 2.36% Zn, 0.11% Cu and 1.3 g/t Ag over 1.42 meters at a depth of 1,126.4 meters along the core. The zone extends to the southeast.
The three holes drilled to test the extension of the South zone in the Fourth Corner area intersected the mineralized zone that is located in felsic volcanites at the contact with sediments and mafic volcanites. Although analytical results are weak, the chloritic alteration in rhyolitic rocks containing the mineralization is strong. The mineralized zone continues at depth and to the SW. The best result was obtained in hole BON-05-03 that cut 1.14% Zn and 2.7 g/t Ag over 6.0 meters at a depth of 346 meters along the core.
In 2008, a Titan-24 surveys conducted by Quantec Geoscience Ltd detected numerous anomalous zones which are considered high priority targets. Quantec recommended a drilling program to verify their findings. According to Quantec the anomalies are “interpreted as representing potential sulphide mineralization and/or alteration zones at depth”. The depth of these anomalies are approximately 300 meters below surface.
Conclusion
The geological environment of the Bonfortel property is strongly favourable for finding volcanogenic massive sulphide bodies. The best target is the extension of the Poirier South zone that extends to the southeast over a strike-length of more than 700 meters commencing at a depth of more than 300 meters along the northwest border of the property. |
