Timmins West Mine

Key Facts

Lake Shore Gold


The Timmins West mine is located approximately 18 kilometres west of Timmins, Ontario, one of the world’s most prolific gold camps. Mineralization is associated with the Porcupine-Destor fault system within the Abitibi greenstone belt. The Timmins West mine is comprised of the Timmins deposit, which has been in commercial production since January 2011, and the Thunder Creek deposit, which achieved commercial production in January 2012. The newly discovered 144 Gap deposit, located approximately 600 metres from the Thunder Creek deposit, is currently under development with commercial production expected in 2017. All three deposits are interconnected by underground drifts.

Tahoe produces ore from the mine via a 5.5 metre diameter shaft with a 6,000 tonne per day hoisting capacity. Ore is accessed using mobile equipment via internal ramps both from surface and the main shaft. Primary mining methods include longitudinal and transverse longhole mining. Timmins West currently produces 2,700 tonnes per day of ore, which is trucked approximately 42 kilometres to the Company’s Bell Creek mill for processing.

As of January 1, 2016, Mineral Resources for Timmins West totaled 5.8 million tonnes with an average gold grade of 4.87 g/t containing 903,000 ounces of gold in the Indicated category and 2.7 million tonnes with an average gold grade of 5.0 g/t containing 429,000 ounces of gold in the Inferred category.
