Fresh water supply is sourced from dewatering wells. Early in the mine life, dewatering well WW-01 will
provide this demand, as it has a proven yield well above the required demands. Fresh water will be stored
in a fresh water tank for u. A future deep bore has been allowed in the mining costs, should the
dewatering well WW-01 draw down early in the mine life.

State Well Logs show that area like a pin cusion.

 Groundwater Hydrology/Dewatering
Groundwater management capital costs are related directly to dewatering of the underground mine. Primary
components of the dewatering system entail dewatering wells with associated pumps and appurtenances,
and sump pumping systems. The pumping systems will discharge water to pipelines for consumption within
the mill or re-infiltration to the aquifer within water management basins.
Initial costs for development of the underground dewatering system are included in mining costs
(Table 21-4).

water is King !

Longyear drilled a 2000 footer in Oct of 2019....


se on site  !!!!

we can only find 18 ac Feet of water owned by NCI..  i another subsction..  it was pointed out that the water quality from the DW Well would be bed into their potable water supply and all of the buildings requiring...

that DW well is from the Underground..  water quality must B pretty pristine 2 not require polishing or chlorination
