Owners

CompanyInterestOwnership
Yorbeau Resources Inc. 100 % Direct
The property is 100% owned by Yorbeau, although parts of it are subject to certain cash payments upon reaching commercial production. It covers about 18 kilometres of the same favourable felsic rocks (Waconichi Formation) that hosts the past-producing high grade Lemoine mine located about 40 kilometres to the southeast (now part of Yorbeau's Lemoine Property).

Deposit Type

  • VMS


Summary:

The Project consists of a number of mineralized zones that have all the characteristics of volcanogenic massive sulphide (VMS) mineralization. VMS-style mineralization at Scott Lake comprises distinct stratabound massive sulphide lenses located mainly along or close to rhyolite-andesite/basalt contacts. In addition to the massive sulphides, separate zones of VMS style disseminated and stringer sulphides, which may or may not be connected with massive sulphide lenses, have been found over a strike length of at least two kilometres.

The Property is located on the north limb of the Chibougamau Anticline. From south to north, the Property stratigraphy consists of a monoclinal sequence extending from the upper units of the Lake Doré Complex and the Chibougamau Pluton to basalts of the Gilman Formation, with remnants of felsic rocks of the Waconichi Formation caught in between. All units are metamorphosed to the greenschist facies. The Property consists of a number of mineralized zones that have all the features of VMS mineralization. VMS style mineralization at Scott Lake comprises distinct stratabound massive sulphide zones located mainly along or close to rhyolite-andesite/basalt contacts and adjacent stringer sulphide zones within altered rhyolite units.

At Scott Lake, the Waconichi Formation is represented at surface by a 600 m thick dome of quartz-phyric rhyolite that pinches out quickly to the west and seems to disappear more gradually to the east. This ........


Mining Methods

  • Longitudinal stoping


Summary:

The preproduction mine development is carried out by a mining contractor and turned over to the mine crews in year one. Contractor rates were used for the preproduction period while manpower estimates were made for the owner operators commencing in year one of the mine production. Although a shaft scenario was considered, an all ramp system was selected as the most appropriate and the mineralized zones are therefore accessed via a ramp system. The Scott Project will take approximately two to three years of initial development to prepare the mine for production. Mining during the LOM will include 50% mineralized material from Longitudinal LH stopes, 26% from Transverse LH stopes, 11% from Cut and Fill stopes, and 13% from development. The Stringer type mineralization will be mined using the Longitudinal stoping method and thus represents a large portion of the production profile.
