> Chebistuan Overview
The Chebistuan Project is an ~120,000 Ha district scale exploration opportunity within the prolific, Abitibi Greenstone Belt. The Chebistuan Property is one of the largest contiguous land packages in the Abitibi (120,000 ha) that covers ~95 km of a series of crustal scale deformation zones and 140km of highly prospective sedimentary-volcanic rock contacts.
> Location and Access
The project is located 30 km west of the town of Chibougamau, Quebec: the largest town in Nord-du-Quebec, which provides excellent infrastructure and an experienced local workforce for exploration and mining activities. Project access is excellent via provincial highways flanking the southern border of the property with an extensive logging road network and high-voltage power transmission lines from James Bay reservoirs crossing the property.
> Geology and Mineralization
The Chebistuan Property is located in the Abitibi Greenstone Belt, which is comprised of highly deformed packages of Archean volcanic rocks, siliciclastic sedimentary basins and coeval intrusive rocks. Deformation along major corridors began in the northern Abitibi with the docking of the Opatica terrane and progressively verged southward forming major gold deposits between 2700 Ma at Detour Lake in the north to < 2670 Ma along the Cadillac – Larder Lake & Porcupine – Destor deposits in the south. The property covers a major deformation zone which juxtaposes two volcanic assemblages similar to the Detour Lake deposit geology. 1st order Au-controlling structures are often located on the margins of clastic sedimentary basins in close proximity to volcanic rocks. The Chebistuan property contains 140km of such contacts highlighting the Au-perspectivity of the area.
The property is located 30km west of the Chibougamau mining camp and 5km west of the Chapais mining camp (6.5 Moz Au; 2.7 Blbs Cu of historic production). The Chibougamau camp has historically been mined and explored for Cu-Au mineralization but the recent discovery of the Nelligan deposit (IAMGOLD – Vanstar Resources) highlights the regional potential for orogenic gold mineralization which has been overlooked in the past.
> Exploration History
Through spatial analysis of historic exploration Kenorland Minerals identified the Chebistuan project area as having very low exploration maturity when compared to the other areas within the Abitibi Greenstone belt. Within the project area a total of 372 historic drill holes have been drilled predominantly targeting geophysical anomalies for Cu-Au targets similar to those of the historic Chibougamau Au-Cu Mining Camp. Very little regional systematic exploration has been conducted. Additionally, pre-competitive government geochemical sampling was dominated by O-Ah horizon soil sampling during the 1980’s which lacked adequate detection limits to target low levels of Au in glacial sediment. Stream sediment sampling during the 1980’s was restricted to the eastern portion of the property with a focus on base metal exploration lacking analysis for Au or other precious metals.
