Hudbay Highlights Proven Track Record, Successful Execution and Strong Corporate Governance

Hudbay Minerals Inc. (“Hudbay” or the “company”) (TSX, NYSE:HBM) highlights its proven track record, successful execution and strong corporate governance following Waterton Global Resource Management’s (“Waterton”) news release naming its nominees for election to the company’s Board of Directors at its next annual shareholders’ meeting.

Proven Growth Strategy and World-Class Asset Base

Hudbay’s Board and management remain committed to the company’s disciplined approach to driving long-term and sustainable value creation. Over the last several years, Hudbay has grown beyond its Manitoba base through acquisition and exploration into a leading mid-tier copper producer with low-cost, long-life assets in Canada, Peru, Arizona, and most recently in Nevada with the acquisition of the Ann Mason project.

History of Successful Execution

Hudbay’s management team has a proven track record of successful new mine development and expertise in both open pit and underground mining. In 2015, Hudbay completed the best in-class development and ramp-up of the Constancia mine in Peru, which is now the lowest cost open-pit copper mine in South America*. Constancia was a greenfield project in a new jurisdiction for Hudbay and the strong community relationships the company has built provides it with the social license to continue to grow its Peruvian business.

During this time, Hudbay also completed the construction of its Lalor underground mine in Manitoba, a deposit that was discovered by Hudbay’s exploration team in 2007 and achieved commercial production only seven years after its discovery. In the first quarter of 2019, Hudbay expects to release a new reserve and resource estimate at Lalor incorporating the gold-rich zones, along with detailed plans relating to the refurbishment of the New Britannia gold mill, which has significant upside potential from nearby satellite deposits. This is one of the many near-term catalysts that could materially increase the value of the company.

Strong Governance Track Record

Hudbay has an independent, diverse and highly-qualified Board that has been consistently recognized for its strong corporate governance practices:

• Hudbay is ranked in the top 20% for overall governance quality by proxy advisor Institutional Shareholders Service (ISS)**;
• ISS has recommended for all directors over the last ten annual meetings (2009 – 2018); and
• The company was ranked in the top 50 by The Globe and Mail’s 2018 Board Games Corporate Governance Ranking, the only base metal miner to be ranked in the top 100***.

Hudbay’s strong corporate governance is complemented by its ongoing commitment to board renewal as evidenced by an average Board tenure of five years and the fact that 60% of Hudbay’s current directors have joined the Board in the last six years.

The company remains open to constructive engagement with all shareholders. To that end, Hudbay previously met with Waterton and invited it to privately share the names and biographies of individuals it thought could potentially add value to the Board. Rather than engaging with the Board through our normal course process, Waterton has repeatedly changed its demands and now has nominated directors to replace the vast majority (80%) of the Board. Waterton, a relatively recent shareholder, is a mining private equity firm that competes with Hudbay for mining assets and may not have interests aligned with other shareholders.

Hudbay will set a date for its annual meeting and file a proxy circular, including a fulsome response to Waterton and voting recommendation for shareholders, in due course.
