Summary:
The property is located within the Michipicoten greenstone belt of the Archean Superior Province. The Michipicoten greenstone belt is a structurally and stratigraphically complex assemblage of volcanic, sedimentary and intrusive rocks that were metamorphosed to greenschist and amphibolite facies. Several suites of plutonic rocks ranging in composition from gabbro to monzogranite and syenite occur in and around the Michipicoten greenstone belt. The property is situated in the Goudreau-Lochalsh gold district of the Wawa gold camp.
The Michipicoten Greenstone Belt area is part of the Wawa Sub-Province and hosts mainly precious metal deposits. Major breaks such as the Goudreau-Lochalsh Deformation Zone (GLDZ) host a number of gold deposits in the Wawa Sub-province.
There are two distinct styles of gold mineralization:
• Orogenic lode-gold greenstone hosted mesothermal gold;
• Intrusive-related ‘porphyry’ disseminated style.
Gold mineralization at Magino Project fits both the sub-volcanic ‘porphyry’ and orogenic style model. Gold associated with the ‘porphyry-style’ at Magino is characteristic of 1) Webb Lake/Lovell Lake Stock granodiorite-tonalite-trondhjemite (GTT) host, 2) widespread phyllic alteration with Nadepletion and K-enrichment, 3) weakly disseminated pyrite ± molybdenite mineralization, 4) weakly veined quartz stockwork network. The orogenic model at Magino involves steeply plunging intersecting lineation in high strain duct ........
Summary:
This Technical Report is based on a conventional open pit mine. Mine operations will consist of drilling small to medium diameter blast holes, ranging from 11.4 cm (4.5 in) to 20.3 cm (8.0 in) and blasting with explosive emulsions. Ore mining will be with two 7 cu m hydraulic excavators (backhoe configuration) to provide better selectivity and control of mining dilution. There will also be a 15 cu m hydraulic shovel for bulk mining of waste areas. A large wheel loader will also be available as a backup loading unit and also to rehandle ore stockpiled at the crusher. Most of the haulage will be with 140 mt class trucks. Ore will be delivered to the primary crusher north of the pit, and waste to the waste storage facility, the Mine Rock Management Facility (MRMF), west of the pit. A significant amount of the waste will also be used in the construction of the Tailings Management Facility (TMF), located west of the pit. There will also be a small low-grade stockpile facility to store marginally economic material for processing during the last few years of commercial pit operations.
A mine plan was developed to supply ore to a plant with the capacity to process 10,000 tpd (3,650 ktpy). The mine is scheduled to operate two 12-hour shifts per day for 365 days per year.
Mining operations commenced during the 1st quarter of 2021. The mining activity to date has been mining waste material from a borrow pit, north of the main mineral deposit, but within the final p ........
