It think it seems quite important to know permafrost distribution and groundwater physical hydrology between the pit and the tailings. Permafrost is also very warm at the site, so I think closure/remediation plans need to consider how the physical hydrology will react to disappearance of permafrost. https://padlet.com/humiliatingpressurestores/iv1unt9jlr8st15p/wish/2976844499 2024-05-01 17:40:37 UTC https://padlet.com/humiliatingpressurestores/iv1unt9jlr8st15p/wish/2976844499 Review in drilling methods used for logging permafrost/excess ice content kmalowany https://padlet.com/humiliatingpressurestores/iv1unt9jlr8st15p/wish/2976845327 2024-05-01 17:41:29 UTC https://padlet.com/humiliatingpressurestores/iv1unt9jlr8st15p/wish/2976845327 I wouldn't recommend application of regional permafrost models to a site-specific scale. The regional model answers different questions than what is needed for a site-specific plan. https://padlet.com/humiliatingpressurestores/iv1unt9jlr8st15p/wish/2976845942 2024-05-01 17:42:07 UTC https://padlet.com/humiliatingpressurestores/iv1unt9jlr8st15p/wish/2976845942 Potential additional characterization on both sides of the Pit kmalowany https://padlet.com/humiliatingpressurestores/iv1unt9jlr8st15p/wish/2976848968 2024-05-01 17:44:51 UTC https://padlet.com/humiliatingpressurestores/iv1unt9jlr8st15p/wish/2976848968 Geochemical stability of mine wastes after backfilling the pit? https://padlet.com/humiliatingpressurestores/iv1unt9jlr8st15p/wish/2976864476 Pit remediation plan: use of low-K vs high-K materials at the base of the bit?

(Cover material, lined vs unlined pit)? I heard sand was proposed in Dome Creek valley. How does sand support revegetation, or might a better growing substrate be more suitable? Sand has high K and low residual water content, and is a poorer material for promoting permafrost formation than finer-grained substrate.
