"On behalf of the entire HDI team, I would like to congratulate Mark Rebagliati on being awarded the J.C. Sproule Northern Exploration Award by the CIM," said Robert Dickinson, Chairman, HDI. "Having known Mark since the 1970's and having had the pleasure of working directly with him since he joined HDI in 1988, I know first-hand that few modern-era geoscientists can match his prolific track record of discovery in Canada and abroad. Mining is a tough business but having Mark on the team makes it that little bit easier."

"In mining it's all about geology and the best approach is to start with the best geologists. Thanks Mark," said Ron Thiessen, CEO, HDI.

Mr. Rebagliati's remarkable ability to identify significant mineral deposits includes an unusually large number of major discovery and project advancements. He led exploration efforts or was part of a team that discovered and advanced the Red Chris, Mount Milligan, Southern Star, Kemess South and IKE deposits in British Columbia, the Pebble East zone in Alaska, the Xietongmen and Newtongmen deposits in China and several deposits at Campo Morado in Mexico. He was also involved in substantially expanding the resources at the Casino deposit in Yukon, and the Pebble West zone in Alaska.
