What We Do

INAP’s objective is to reduce the liability associated with sulphide mine materials. This is pursued in three ways:

  • Networking and Information-sharing
  • Technology Transfer
  • Gap-driven Research

Networking and Information-sharing
The INAP network brings together the most recent acid drainage experience and knowledge and allows us to:

  • Build on existing research and avoid duplication
  • Learn from the achievements and challenges of others
  • Benefit from expert peer review on key acid drainage issues

Technology Transfer
INAP supports and organizes technical transfer activities at different levels. Workshops bring together management and operations personnel from companies around the world, and are instrumental in promoting the implementation of good practice. INAP has also published an internet-based global best practice guide (GARD Guide) for the prevention and mitigation of ARD, which is found at (www.gardguide.com). Capacity building activities for governments and regulatory bodies are also supported by the network. In addition, INAP plays a key role at international events that involve various stakeholder groups, and is a key supporter of the International Conference on Acid Rock Drainage (ICARD).

INAP is increasingly being acknowledged as the leading international acid drainage research group. Research projects are member driven and address the most significant information gaps in the prediction, prevention, management, measurement and treatment of acid drainage. As a network involving a number of companies, INAP also facilitates projects that can only be developed through co-operative efforts.

INAP also partners with key regional Global Alliance AMD organizations:

INAP History

At the International Conference on Acid Rock Drainage (ICARD) in Vancouver in 1997, informal meetings were held among industry, government, consultants and university representatives to discuss initial ideas on an acid drainage initiative similar to the Canadian Mine Environment Neutral Drainage (MEND) Program – but on a global scale.

An industry committee with representatives from Canada, Australia and the United States was formed to explore possibilities. At a meeting in early 1998 attended by representatives from 18 companies,14 universities, consultants and government experts, the need for the creation of a new group - the International Network on Acid Prevention (INAP) - was strongly endorsed. Conclusions from the discussions were that:

  • It would be useful to develop a knowledge-base covering collective experience from around the world, rather than focus exclusively on research.
  • The need to share industry information on past successes and failures would be a good basis upon which to build the network.

In April 1998, six companies agreed to formalize the International Network for Acid Prevention (INAP) and the network was officially launched in October, 1998.

The founding companies were: BHP Copper, Cyrus Climax, INCO, Noranda, Placer Dome and Rio Tinto.
