A key part of our plan to increase production by 20% by 2021, Borden will be Canada’s first all-electric underground mine.

Quick Facts
Location Chapleau, Ontario
District Porcupine
Ownership 100%
Type of Mine Underground, open pit and stockpiles

Located approximately 160 kilometres west of the Porcupine mine in Chapleau, Ontario, Borden has the potential to enhance the long-term economics of Porcupine, where its ore will be processed.

Borden is set to be Canada’s first all-electric underground gold mine, which will be safer for our employees and have a smaller environmental footprint.

We are negotiating with the First Nations communities in the area, and have signed agreements that reflect our commitment to ongoing consultations with local First Nations.

Borden is a key part of our plan to increase production by 20% by 2021, and is expected to comprise approximately one-third of Porcupine’s production in 2020. We expect to begin commercial production in the second half of 2019.

The Borden deposit is a new style of mineralization in the underexplored Borden Lake belt where our large consolidated claim package extends to a thousand square kilometres. With no mining history, there is very little geological data available about the region. Goldcorp’s primary exploration focus is to understand the geology of the area and identify a portfolio of targets.

Other exploration goals include:

  • Continuing to develop the geological model of the deposit
  • Testing the extensions of the deposit
  • Evaluating the 1,000 square kilometre land package to develop a portfolio of targets for ongoing evaluation.
