• The Project’s first pit, Three Hills Mine, is fully permitted and is now at 100% construction

readiness, with a fully developed construction plan, a level -3 construction schedule, and

issued-for-construction drawings, and waiting for a much more favorable pricing environment

prior to making a construction decision.

• The Project’s second pit, Hasbrouck Mine, is scheduled to start producing two years after the

start of the first pit, and h as a federal permit and is close to being at 100% construction

readiness.

• The Company has conducted internal studies t o investigate reducing both greenhouse gas

emissions and operating costs, including switching to electric equipment from diesel mining

equipment, and has commissioned NV Energy to study the supply of the additional power

needed for this.

• The Company is also studying reducing greenhouse gas emissions and operating costs by

switching to grid power at Three Hills Mine instead of the currently planned and permitted LNG-

generator.
