From the website:

"The British Columbia MEND ML/ARD Workshop was created to address the limited long-term operating experience for most ML/ARD prediction and mitigation measures and the need for a cost-effective technical forum where challenges and field-scale results can be presented and discussed. Each year the workshop invites leading practitioners and researchers from British Columbia, Canada and abroad to share their knowledge and provide fresh insight into how the tool box of technologies and practices to address ML/ARD issues can be improved. The workshop also endeavours to enable the sharing or experiences and productive dialogue between people from similar and differing communities of interest.
