RE:RE:RE:RE:Likely Very Little Sediment (better word choice)Ridgeback,
What I have stated was based on the current drilled results from the first 8 holes, where they found a lot of silver still remains in the sample (up to 330gpt) and Au (up to 8.68gpt) and SKE have computed the AuEq as reproted in their NR. Also, the info below came from reports prepared for the old operator (Barrick), including one pperaped by AMEC on the Closure of the AWF which was intended mainly as a waste rock facility (including some minor cemented rock fill along with most of the "low grade" Rhyolite, and minor tailings, mine fines and water treatment sluge). This facility was never intended as a leaching facility (perhaps, you were talking about a potential future option?), but I have not come any suggestion about leaching facility at AWF by Barrick (or SKE...SKE would perhaps want to put this through the same mill for procustion of concetrates rather than leaching using Mercury). The waste rock at AWF just grew and grew (and could contain quite a bit of gold at over 1800/oz) and the best way to control it from Barrick's point of view (from dust flying roud nd oxidation due to exposure to air is to keep it under a couple of m below water.

Gold equivalent (AuEq) is calculated via the formula: Au (g/t) plus (Ag (g/t) divided by 75). True widths equate to 100 per cent of reported sample lengths. Grade-capping of individual assays has not been applied to the Au and Ag assays informing the length-weighted AuEq composites. Metallurgical processing recoveries have not been applied to the AuEq calculation and are taken at 100 per cent. Samples below detection limit were nulled to a value of zero.
Historical waste facility demonstrates significant grade and potential
Situated west of the Eskay Creek mine site, the Albino waste facility was utilized by former operators as a subaqueous repository for mine waste management and included both mine waste rock as well as mill tailings.
During historical operations, the underground mine development was largely tunnelled in the often-mineralized footwall rhyolite sequences below the mined contact mudstone. Although these rocks possessed variable Au-Ag grades, former operators considered the rhyolite-hosted mineralization uneconomic due to the high cut-off grades required at the time. Hence, this development rock was transferred to the AWF for subaquedeposition.Leaching.
Leach Au. disolved in tailing easy stuff. Ag will be free and we have years of it. How much? Au will disolve in Mercury . How much yet to be known?
No more debate wait and see? I have worked in refineries that can suck out ounces. No matter 400 K or whatever reclaimaintion is all good.
