Modification 3 (MD03)
Dear Mr. Cazier,
RECEIVED
DIMSION OF RECLAMATION
MINING AND SAFETY
Attached is a modification to Black Range Minerals (BLR) existing DRMS NOI File No. P -2009-
025. The modification is to collect a one -time prospective bulk sample of up to 200 tons from the
Hansen Uranium Deposit via hydraulically jet- cutting a cavern of rock from within a drill hole.
Modifications to the subject permit form are as follows:
- III. Project Description parts 2, 4, 5, and 6
- IV. Operation and Reclamation Measures parts 4 and 5
Prospecting types and methods are modified to include a shaft (the vertical drill hole access) and a
cut (the hydraulically jet -cut cavern) within the Hansen Uranium Deposit for the collection of a one-
time bulk sample. Surface disturbance associated with the bulk sample will be slightly larger than
the current average disturbance. The bulk sample operation will require more area primarily for
storage tanks and additional mobile infrastructure (see Attachment 4). Surface disturbance for this
operation will be within our currently approved and bonded amount.
Prior to the bulk sample, a groundwater monitoring well will be installed directly down gradient from
and within the same formation and hydro - geologic horizon as the bulk sample zone. A drill rig will
complete a drill hole shaft and then lower a hydraulic jet cutting tool through the drill hole to the
sample zone. The jet tool will cut sample material from the wall of the drill hole via pressurized
water stream and the material will be lifted through the drill pipe to the surface via air lift suction. At
the surface, material will be directed onto a gravel shaker where the sample stream will be split.
The coarser material from the shaker will be directed into a mobile storage bin and the finer
material and water will be directed into mobile upright tanks. Decanted water from the upright tanks
will be circulated as needed for cutting additional sample and a vacuum truck will remove the
settled solids. Cutting and extraction of sample material for the one -time prospective bulk sample
duration will be limited to no more than 200 tons of dry material equivalent.
