-- Hukill Gulch Millsite, DRMS Permit #M-2009-076 --
1 Description of Mining Activities
Venture Resources has applied for a I I0(d) Limited Impact Hard Rock Metal Mining Permit from the Colorado
Division of Reclamation, Mining and Safety (DBMS) and has been assigned to M-2009-076. The name of the
project is "Hukill Gulch Millsite".
Operations will be conducted in Clear Creek County, just west of the Virginia Canyon vicinity near Idaho Springs.
Access to the property is found heading north from Idaho Springs 1.3 miles on Two Brothers Road. The property is
primarily situated in the SW '/4 of the SW I/4 of Section 26 of Township 3 south and Range 73 west. More specific
detail can be found in Section 3 - Site Maps of this SWMP (maps and drawings correspond to DRMS permit
drawings).
The proposed Venture Resources Hukill Gulch Millsite project will be involved in operating a mineral processing
mill and constructing a tailings impoundment to begin cleaning up and processing pre-existing abandoned mine
waste rock and/or ore for trace precious metal content and environmental remediation. Milling techniques used are
• two-stage crushing, ball mill grinding, concentrating table gravity separation, flotation concentration, and slurry
tailings disposal. Thule are no hydrometallurgical or other leaching extraction activities proposed. Concentrate
products are shipped to third-party refiners.
This project extracts nearly all of the acid-forming minerals in waste rock that are the source of acid-runoff that
plague this historic mining district. By doing nothing, these piles of pre-existing waste rock will continue to leach
acid and heavy metals for a very, very long time. By designing a carefully regulated and engineered program a
solution can be achieved. Along with the environmental benefits of this cleanup, new employment opportunities
and increased business within the local economy will develop.
Phase I of operations, the scope of this permit application, employs the use of a mobile mineral processing mill (40-
80 ton/day), construction of a tailings impoundment and processing approximately 8,000 tons of pre-existing
abandoned mine waste rock located within the affected area of the proposed Tailings Impoundment (see Section 3
for site maps and drawings).
Total affected area is 8.76 acres, divided as follows: 8.125 acres in Tailings Impoundment and 0.635 acres at the
Mobile Mill Site. This coincides with the DRMS permitted area, or more specifically affected area.
2 Area Subiect to Effluent Limitations Guidelines
There is ZERO process water discharged from this operation. All process water is regulated under DRMS
permitting and is within engineered liquid containment systems (ie HDPE lined tailings impoundment, double-
walled process piping, sheltered intermediate stockpiles, etc.). Process water is recycled. A CDPS industrial
discharge permit is not required.
. There are no equipment wash-down activities as part of this operation.
