Highlights

• At Borden, bulk sample extraction began in August 2018, two months ahead of schedule, with operating permits expected in the fourth quarter of 2018. The mine electrification process is underway, and commercial production remains on track for the second half of 2019.
  
  
• The Century prefeasibility study remains on schedule for completion in the fourth quarter of 2018, and the associated project description has been submitted and is currently undergoing a 20-day public comment period in order to move on to the next stage of permitting.
  
  
• The Coffee project completed the adequacy review phase of the permitting process with Yukon Environmental and Socio-economic Assessment Board (YESAB) in August, 2018 and has now entered a 30 to 60 day public comment period.  Production is still expected to commence in 2021.
  
  
• At Peñasquito, the Pyrite Leach Project has completed construction with commissioning further accelerated to the third quarter of 2018, two quarters ahead of schedule. First gold and commercial production are expected in the fourth quarter.

Borden Project Continues to Advance; Ramp Development on Schedule

At Borden (100% owned, Canada), all mine infrastructure to support production is in place. Ramp development has now reached approximately 1.6 km in length with a depth of 300 m, and is on schedule.

Figure 1: Visual Review of Annual Mine Plan (Mine-Wide).

The bulk sample extraction began in August, two months ahead of schedule, with a first zone of extraction on levels 225 and 240.  The continuation of the exploration ramp is leading toward level 420 m, which will be the final phase of the bulk sample program. In 2018, the bulk sample extraction will de-risk the project and allow for recovery of 4,000 ounces of gold, as well as learning and confirming the main characteristics of the ore body such as rock stability, geology and recoveries.

All operating permits are expected to be obtained by the fourth quarter of 2018, allowing an increased pace of development along with construction of the remaining critical mine infrastructure including ventilation raise and secondary egress for the operation. Permit applications for industrial sewage, air and water have been through the 30-day Environmental Registry phase and are currently being finalized. The next milestone will be receiving acceptance of the mine closure plan, expected 45 days after the August 22, 2018 submission.

The mine is expected to begin commercial production, as planned, in the second half of 2019. Borden is focused on using new technologies, including mine electrification and full connectivity, with the goal of increasing efficiency and enhancing safety. Currently, the exploration ramp is using mainly electric vehicles. The fleet is composed of state of the art mining equipment, automated battery/electric jumbos and battery bolters. All services vehicles are electrified, including a conventional grader which was converted into a battery-operated unit.

As a leader in mining innovation and adopter of clean technology, Goldcorp has sought partnerships with suppliers, Government, First Nations, associations and other mining companies. For example, the Government of Ontario has agreed to invest $5 million into the deployment of the all-electric fleet through its target greenhouse gas program.

With all-electric underground mine operations, Goldcorp estimates that operating costs will be reduced by over $9 million per year due to the elimination of approximately two million litres of diesel fuel, and with reduced ventilation needs, a decrease of approximately 32,000 MWh of electricity and a corresponding decrease in propane required to heat the ventilation. Importantly, we expect a reduction in annual green house gas emissions of more than 7,000 tons, or a seventy per cent reduction over a baseline mine.

On June 6, 2018, Goldcorp announced the signing of an Impacts and Benefits Agreement with three First Nation communities with respect to the development and operation of the Borden project. The formal signing of the agreement follows successful negotiations with Brunswick House First Nation, Chapleau Cree First Nation and Chapleau Ojibwe First Nation, and is a milestone marking the first time these three First Nation communities are involved with a mining project.

Century Prefeasibility Nears Completion and its Associated Project Description Has Been Submitted.  

The Century (100% owned, Canada) prefeasibility study is on schedule to be completed in the fourth quarter of 2018 and the feasibility study by the first quarter of 2020. The submitted Project Description has successfully met the criteria for the Prescribed Information for a Description of a Designated Project Regulation, in accordance with the Canadian Environmental Assessment Agency (CEAA) 2012 requirements and is now undergoing a 20-day public comment period. Baseline field studies and modelling are underway to support the permitting process.

A series of trade-off studies to improve mining and processing efficiencies were completed to present the single go forward option which then became the basis for the prefeasibility study. Trade-off studies completed included: truck and shovel capacity, co-mingling of tailings with waste rock (Eco-Tails), filtered tails, thickened tails, conveying of rock from the pit, autonomous haulage and optimized process plant design.

Coffee Gold Project Deemed 'Adequate' and Moving into Public Consultation followed by Screening

The Coffee Gold Project (100% Owned, Canada) has been deemed adequate by the Yukon Environmental and Socio-economic Assessment Board (YESAB) in August 2018. This is positive step forward though the first stage of the permitting process outlined within the Yukon Environmental and Socio-economic Assessment Act (YESAA). Public consultation begins immediately.

The Coffee Gold Project continues to advance engineering, exploration and permitting activities with production expected to commence in 2021.

On April 30, 2018, Goldcorp and Tr'ondëk Hwëch'in (TH) announced that the parties had entered into a Collaboration Agreement relating to the Coffee gold project. The Agreement represents a significant milestone towards building a long-term relationship and is a critical step towards delivering economic opportunities for TH and its citizens through the development of the Coffee Gold Project in the Yukon.

Pyrite Leach Project at Peñasquito Remains Ahead of Schedule and Under Budget

At Peñasquito (100% owned, Mexico), the Pyrite Leach Project is now fully constructed and is undergoing pre-commissioning together with area-based commissioning. First gold and commercial production are expected in the fourth quarter of 2018.

The Carbon Pre-flotation component of the project is now allowing Peñasquito to process ore which was previously considered uneconomic, including significant amounts already in stockpiles. The project was completed under budget in the second quarter of 2018 and has been operational since May 2018. With a focus on safety and reliability, PLP has been delivered with zero Lost Time Incidents and an All Injury Frequency Rate of 0.09.
