Summary of Mineral Reserve and Mineral Resource Estimates
On February 4, 2015, the Company reported consolidated Mineral Reserve and Mineral Resource estimates for its mines and development projects as at December 31, 2014. A consolidated summary of total gold, silver and copper contained within New Gold’s global Mineral Reserves and Mineral Resources is set out in the table below. New Gold’s Mineral Reserve and Mineral Resource estimate as at December 31, 2013, which was included in New Gold’s annual information form for the year ended December 31, 2013, had included Mineral Reserves in Mineral Resources, as permitted by NI 43-101. New Gold has revised its approach to the reporting of Measured and Indicated Mineral Resources. Measured and Indicated Mineral Resources are now reported exclusive of Mineral Reserves. As a result, in the Mineral Reserve and Mineral Resource estimates presented below, Mineral Resources do not include Mineral Reserves.
New Gold’s Mineral Reserve and Mineral Resource estimates have been reviewed and approved by Mr. Mark A. Petersen, a Qualified Person as defined under NI 43-101.
