3. Phase I Project Objectives • Determine and engage stakeholders • Identify existing guides • Develop GARD Guide framework • Define GARD Guide content • Determine position on INAP website • Develop action plan to develop GARD Guide • Develop terms of reference for consultants for next phase as appropriate • Estimate costs and timeframe to produce the GARD Guide

4. Phase I Activities • Established a Steering Committee • Produced components of development plan for review • Conducted 3 Steering Committee calls, several individual calls and many e-mail communications • Completed draft Phase I project report • Collected and responded to Steering Committee Comments on draft report • Prepared INAP and GA presentations

5. GARD Guide Business Case In comparison to existing ARD Guides, the GARD Guide would be: • Current with available scientific and engineering understanding • Comprehensive by covering all aspects of ARD formation and management • Global by considering geographic differences in climate and environmental setting • User friendly with web based access and search capability • Updatable via the web • Accessible to a broad range of readers from those with a lower technical knowledge to experts

6. GARD Guide Characteristics • Flexible to accommodate site-specific issues • Avoid duplication and build on existing guidelines and compendiums • Be consistent and promote a systematic approach • Founded on a risk based approach • Endorse a pro-active approach and encourage reduction and control at the source • Be a “how to” guide and not a regulatory tool or a design manual • Be globally targeted and avoid a NA bias • Be based on proven, field tested technologies • Cater to the life cycle of a mine (cradle to cradle)

7. Scope of GARD Guide • Acid rock drainage, neutral mine drainage and saline drainage where contaminants are released from solid to liquid phase by sulphide mineral oxidation • Includes: tailing, waste rock, underground mine and pit walls, pit lakes, spent ore heaps and low grade stockpiles • Applies to all commodities including base metals, gold, coal and uranium • Does NOT include: • Acid sulphate soils • Dissolution of sulphate salts produced by pyrometallugical or complex hydrometallurgical processes (eg. roasters and autoclaves)

8. Definitions, Nomenclature and Accessibility

9. Target Audience • Companies, governments, consultants, researchers, educators, communities, communities of interest, bankers and NGO’s • Primary target audience is a scientist or engineer with a reasonable background in chemistry and the basics of civil engineering but not necessarily specifically related to acidic drainage.

16. Options to Develop GARD Guide

17. Steps in GARD Production • Select and set up web based document management system • Select method to obtain Guide technical input • Identify/confirm roles and individuals to fill the roles • Issue RFP for technical input and select technical contributor(s) • Finalize Table of Contents and knowledge maps • Develop style guide • Assemble first draft of chapters • Review chapters with Steering Committee and peer reviewers • Distribute draft chapters and post on web site for review • Test chapters with selected users in industry/government/NGO’s • Consolidate comments and produce second draft of chapters • Engage technical writer to edit chapters • Engage web author to assemble chapters for the web • Test web based Guide with selected users • Revise and “go live” • Establish Guide usage monitoring and maintenance system

18. Technical Contributor Options • Single consultant • Multiple consultants by chapters (including authors of previous guides) • Multiple consultants/authors work on chapters (including authors of previous guides in global working group) • Donations for chapters • Company contributions • Government research arms • Steering committee contributions • Mining associations manage chapters • Global Alliance manage chapters

19. Technical Contributor “strawman” • The GARD Guide – ed/LTC with input from INAP, Global Alliance and Steering Committee • The ARD Process – selected consultant, possibly from academia, chosen through RFP • Corporate, Regulatory and Community Framework – selected consultant, possibly from academia, chosen through RFP • Defining the Problem – Characterization – selected consultant chosen through RFP • Prediction – selected consultant chosen through RFP • Prevention and Control – selected consultant chosen through RFP • Drainage Treatment – selected consultant chosen through RFP • Monitoring – selected consultant chosen through RFP • Management and Performance Assessment – selected consultant chosen through RFP • ARD Communication and Consultation – ed/LTC with input from INAP, Global Alliance and Steering Committee • ARD Management and Sustainability Framework – ed/LTC with input from INAP, Global Alliance and Steering Committee ed - editor LTC – lead technical consultant

20. Document Management

22. Position on INAP website

23. Challenges • Engaging a very busy industry and consulting community • Synthesizing the vast body of information • Resolving differences in opinion • Making complex topics understandable and useful • Ensuring broad acceptance • Funding

24. Time and Cost Estimate • 2 years • $250,000 US Doable but aggressive!!

25. Unresolved Issues • scope of the Guide - special metallurgical process wastes (eg. roasters and autoclaves) and ancient oxide caps • use of the term "ARD"  and other nomenclature.  • organizational structure to produce the Guide. • Technical contributors: • splitting chapters • selected contributors • single or multiple RFP’s to consultants • picking and choosing members of consultant teams • engaging past guide authors • Steering Committee drafting • use of workshops • simple, useable vs comprehensive knowledge maps • possible phased approach/trial run chapter • use of literature reviews and past Guides  • role of the GA • GARD Guide roll-out step added to development plan • when to test the Guide with potential users • timeline (and cost)

26. Recommendations INAP should: • Proceed with the GARD Guide development • Address acidic, neutral and saline drainage • Target scientist or engineer reader • Produce a Guide that is: • “how to” - not a literature summary • web-based with extensive search capability • less than 350 pages + appendix • Use technical editor or lead consultant approach • Issue a RFP for at least some chapters • Develop a style guide • Establish an external peer and stakeholder review process • Consider a phased approach to Guide development

27. Next Steps • Provide guidance on unresolved issues • Review, modify and finalize GARD Guide development report • Decide on a phased approach • Identify and secure funding • Select an option for Guide development organization • Select editor or lead technical consultant to manage development of the Guide • Fill the roles in the organization chart

28. Phase I work to complete • INAP presentation • GA presentation • Final steering committee calls • Finalize phase I report Expected completion – December 20, 2006

29. Phase I Project Budget Status • $28,500 CDN + GST budget (included $5,500 for optional travel/presentation) • $15,000 CDN* spent to date • $18,500 CDN* forecast to complete (assuming no significant new items) • $10,000 CDN* forecast under budget * Includes GST
