Kirkland Lake Gold Inc.

Environment

As a society we must balance the creation of goods and services that supply our needs, wants and economic growth with the resulting use or consumption of the earth’s resources. Kirkland Lake Gold Inc. recognizes that mining activity impacts the natural and human environment as well as the economic environment. Responsible mining must involve environmental consideration in all phases of our operation. We conduct our business at Kirkland Lake Gold Inc. responsibly and in a manner designed to protect our employees, public health and the environment in accordance with the principles outlined below.

Management Commitment

Management commits the necessary resources and designates appropriate accountabilities to attain operational performance consistent with this Statement of Environmental Policy and Principles.
