TECHNICAL REVISION NO. 5—Plant Modification <br /> HUKILL GULCH MILLSITE (DRMS Permit No. M-2009-076) <br /> Venture Resources, Inc. <br /> Venture Resources, Inc. (Venture)hereby submits this application for Technical Revision No. 5 to Permit <br /> No. M-2009-076 in order to secure Division of Reclamation, Mining and Safety (DRMS) approval for a <br /> minor modification to the approved process plant configuration currently in place at the Hukill Gulch Mill <br /> site. Virtually all other aspects of the Permit, as approved, are to remain unchanged. The proposed <br /> modification to the process plant configuration, and resultant change to the process flow schematic, <br /> consists solely of the following: <br /> Proposed Plant Modification <br /> Removal(and offsite disposition) of two of the existing mobile trailer units which (as per the approved <br /> permit) comprise(a) the ball mill; and, (b) the combined froth flotation and gravity table gold recovery <br /> circuit unit operations, respectively. In place of the two separate mobile trailer units, Venture will <br /> construct a singular structure to accommodate both milling and gravity recovery circuits, thus <br /> eliminating the froth flotation and gravity table equipment from the proposed (new) process flow <br /> schematic (Venture will, however, retain the right to reintegrate froth flotation processes into the <br /> process flow schematic at a later date, if determined desirable). The proposed structure will be a pre- <br /> engineered, temperature-controlled enclosure that will be erected/assembled onsite atop a two-level, <br /> slab-on grade foundation. <br /> In conjunction with this new structure (which will accommodate both milling and gravity recovery <br /> circuits), Venture will modify the (as-approved)process flow schematic. As per the approved process <br /> flow schematic, the crushing circuit will remain unchanged,and minus 3/8--inch material will continue <br /> to be introduced to the(reinstalled) ball mill as before. However, ball mill discharge will now report to <br /> a gravity concentrator. Gravity concentrator underflow (concentrate) will be collected (as saleable <br /> product) and overflow (middling) will be routed to a cyclone unit. The cyclone underflow (plus 50 <br /> mesh) will be returned to the ball mill for regrind and overflow (minus 50 mesh) will be routed to a <br /> second gravity concentrator. Underflow (concentrate)from the second gravity concentrator will be <br /> collected (as saleable product) and overflow (tailing) will be routed via slurry pipeline (per the as- <br /> approved permit conditions)to the downgradient-located tailing storage facility. <br /> The proposed modification is to occur at, and affect only that permit sub-area that is currently associated <br /> with milling and processing activities. Inasmuch as the proposed modification only affects the gold <br /> recovery process (i.e., the comminution process remains unchanged), the produced tailing particle size, <br /> size distribution, and solids/liquids ratio will be virtually non-affected. Thus, there will be no measurable <br /> effect on the design and/or operation of the (as-approved) downgradient and associated tailing storage <br /> facility. <br /> Venture envisions that the proposed modification will, as a result of the addition of a new structure, <br /> introduce a(theoretical) incremental effect on site reclamation obligations at such time milling operations <br /> 1 <br />
