The deposits located on the Garrison and Golden Highway Properties are interpreted to be structurally- controlled orogenic gold deposits in an Archean greenstone belt setting. This deposit type is a significant source of gold mined in the Superior and Slave provinces of the Canadian Shield. These deposits are typically quartz-carbonate vein hosted and are distributed along crustal-scale fault zones that mark convergent margins between major lithological boundaries such as those between volcano-plutonic and sedimentary domains. The greenstone- and sediment-hosted quartz-carbonate vein deposits are structurally controlled, epigenetic deposits characterized by simple to complex networks of gold-bearing, laminated quartzcarbonate structure-fill veins. These veins are hosted by moderately to steeply dipping, compressional, brittle-ductile shear zones and faults with locally associated extensional veins and hydrothermal breccias.

The Tower Gold Project to date hosts nine gold deposits: six on the Golden Highway property, and three on the Garrison property. Most of the gold occurrences are found within a corridor parallel to the DPFZ. This corridor contains two highly prospective geological settings: a North Corridor with sheared mafic and ultramafic volcanic units and syenitic intrusive complexes, and a South Corridor defined by Timiskaming sediments containing banded iron formation (BIF).

The Tower Gold project consists of seven mineral deposits (Southwest, Westaway, 55, Windjammer, Garrcon, 903 and Jonpol). The overall steady state production rate is 7.0 Mt/a at 0.94 g/t over the 24-year Life of Mine (LOM). Extraction of the economic mineable inventory is proposed through a combination of open pit and underground mining as this presented the best case from an economic, environmental, and sustainable development perspective, with open pit mining occurring over two phases.

For the first 11 years of the project, the open pit mine will be responsible for a steady state production of 6.1Mt/a at an average grade of 1.03 g/t. Once the underground mine is complete, the open pit will be responsible for a steady state production of 7Mt/a at an average grade of 0.75g/t until pit depletion in Year 20, followed by 4 years of low-grade stockpile feed at an average grade of 0.38g/t. The Tower Gold project will employ a conventional truck shovel open pit mining method comprising separate waste and mineralized material equipment fleets to improve on selectivity and reduce waste removal costs. The mineralized material fleet consists of 12 m³ excavators and 92 tonne trucks while the waste fleet consists of 29 m³ excavators and 227 tonne trucks.

Underground Mine Design
The Tower Gold Project will be extracted with a combination of open pit mining for mineralization closer to surface, and underground mining for mineralization at depth. The combined out ........
