The vegetation test plot on the excavated pond -nods was not <br /> constructed as planned and mentioned in the last annual report. <br /> The reasons for this are: (I ) the Division was not receptive to <br /> the idea; and (2) the pond muds were removed to Tailings Pond <br /> No. 3 , <br /> A new lime reagent feed system was gozcbased for the Terry <br /> �unoel . It was not installed because manufacturing delays caused <br /> it to be received after snowfall and it could not be installed . <br /> It is to be installed upon opening of the road in May I989 , <br /> The old waste dump mentioned in the last annual report and <br /> A,zeodmeot 3 was removed and used to cover the toe of the Terry <br /> Tunnel mine bench as stated in the plan . <br /> Planned activities for I989 include installing the reagent feed <br /> system as mentioned above, cleaning the settling ponds and <br /> sealing Dnod No. 2 , and improving the pond bypass and decant <br /> system to make pond cleaning operations less disruptive to water <br /> treatment. <br /> Sunnysidei k - Plate No. 2 <br /> open pit mining was conducted in Suuoyside Basin as covered in <br /> Amendment 3 . The pits were on tne Washington Vein and the <br /> Sunnyoide Vein. The scale of the pits was much smaller than <br /> submitted in Amendment 3 because of actual conditions found at <br /> the site versus the original plan . The topsoil stripped from the <br /> pit areas was stockpiled and seeded . The overburden and waste <br /> rook were stockpiled for later use in reclaiming the Lake Emma <br /> nnle as approved in the Technical Revision addressing acid <br /> mitigation plans for the temporary waste storage piles. The <br /> waste rock stockpiles were treated with 2zoMac during October <br /> 1988 as per this same Technical Revision . <br /> The zevegetatioo test plots in the lake sediments were <br /> constructed as per the report and layout map submitted . <br /> Evaluation of initial success has not been determined because of <br /> snow cover. <br /> During open pit mining on the 3000yside Vein, a raise was <br /> encountered that was riot anticipated. The raise opens into a <br /> large otoDe , so baokfilliog is not feaaible , rhe bole was <br /> temporarily timbered over and fenced for safety. D Permanent <br /> cover will be constructed to seal the hoIe . A Technical Revision <br /> will address the propose,.-] construction before commenceoeot. <br /> A surface subsidence occurred in toe water diversioo trench south <br /> of the Lake Emma hole. An nodezqzoond atope exists in that <br /> location approximately 200 feet unCergrouod. It is not normal <br /> for piping or caving like what must have occurred to bap'pen at <br /> this mine . The subsidence was filled and a half-culvert was <br /> suspended over the site to keep the water from entering the <br /> subsidence. After settling stops , tbe subsidence will be <br /> peznoaoeotly repaired . <br /> - 3 - <br />
