NWT Diamonds Project Preface

This is a Summary of the Environmental Impact Statement (EIS) for the NWT Diamonds Project, a

joint venture between BHP Diamonds Inc. and its Canadian partners the Blackwater Group. The joint

venture partners believe that this project, the culmination of more than ten years of prospecting in the

North, will become Canada’s first diamond mine.

The Proponent of the NWT Diamonds Project is a joint venture of BHP Diamonds Inc. (51%) and the

Blackwater Group (49%). The Blackwater Group is composed of Dia Met Minerals Limited, Charles

Fipke, the Canadian geologist who originally discovered diamonds and his prospecting partner,

geologist Dr. Stewart Blusson. BHP Diamonds Inc. is part of BHP Minerals. BHP Minerals employs

15,000 people in 30 countries. BHP Minerals is a business group of The Broken Hill Proprietary

Company Limited (BHP). BHP is Australia’s largest industrial and natural resources company. BHP

Diamonds Inc. is the Operator of the project on behalf of the project Proponent.

This EIS Summary and its four supporting volumes are being submitted to the Federal Environmental

Assessment Review Panel in compliance with project specific guidelines issued by the Panel on May

23, 1995. This report represents three and one half years of intensive sampling and exploration, more

than two years of environmental baseline work, more than three years of extensive community consul-

tation and more than two years of detailed engineering design. Detailed information and analysis is

provided in the four accompanying volumes of the EIS plus a number of appendices. These volumes

are titled Project Description, Environmental Setting, Environmental Management and Environmental

Impacts and Mitigation. These volumes outline the details of the project, the nature of the potential

impacts of the project and methodsthat the Proponent will use to address and mitigate these impacts.

“The Dogribs seek greater control over development in our traditional territory because we are the ones who will suffer if there are any negative impacts. Unlike the developers, we and our descendants are not going anywhere.”
