First Quarter Highlights
• Net earnings were $67 million, or $0.08 per share, compared to net earnings of $170 million, or $0.20 per share, for the first quarter of 2017. Operating cash flows for the first quarter of 2018 were $271 million compared to $227 million for the first quarter of 2017. Adjusted operating cash flows(1) were $350 million for the first quarter of 2018 compared to $315 million for the first quarter of 2017.

• Gold production of 590,000 ounces at all-in sustaining costs(1) ("AISC") of $810 per ounce, compared to 655,000 ounces at AISC of $800 per ounce for the first quarter of 2017. Full year 2018 guidance reconfirmed for gold production of 2.5 million ounces (+/-5%) at AISC of $800 per ounce (+/-5%).

• Solid execution on project pipeline in support of the Company's 20/20/20 growth plan. The Peñasquito Pyrite Leach project advanced to 86% completion, ahead of schedule, the Musselwhite Materials Handling project advanced to 65% completion, on schedule and 10% below budget and the Borden project is on track for commercial production by the second half of 2019.

• Key milestone achieved with the completion of the pre-feasibility study at NuevaUnión and advancement to the feasibility stage. The pre-feasibility study outlines a combined and phased approach to the development of the Relincho and La Fortuna deposits at NuevaUnión with a project containing 8.9 million ounces of proven and probable gold mineral reserves and 17.9 billion pounds of proven and probable copper mineral reserves (100% basis) to be produced over a 36 year mine life. The NuevaUnión project is foundational to the Company's Beyond 20/20 program and its feasibility study is expected in 2019.

• Program to implement $250 million of sustainable annual efficiencies by the middle of 2018 is on track with $210 million achieved as at the end of the first quarter of 2018 across the Company's portfolio. More than 100% of the $250 million of efficiencies have been identified, with the program likely to be extended and the efficiency target increased, after the Company achieves its current target.

"Our operations again delivered on target quarterly results while we continue to execute very well on our robust pipeline of growth projects, which together with excellent exploration results from across our portfolio, continues to enhance confidence in our 20/20/20 plan of growing production and reserves by 20%, and reducing AISC by 20% by 2021," said David Garofalo, President and Chief Executive Officer of Goldcorp. "The completion of a solid pre-feasibility study at NuevaUnión and the acceleration of study work, exploration and engineering at Century and Norte Abierto underpin our Beyond 20/20 pipeline of potential new long-life, low-cost and large-scale mines."
