Name of the Project
CK gold project.
Location
Laramie County, in Wyoming, in the US.
Project Owner/s
Nasdaq-listed exploration and development company US Gold Corp.
Project Description
A prefeasibility study (PFS) has delivered robust economics.
The project has measured and indicated resources of 1.58-million gold-equivalent ounces.
The PFS envisages an openpit mine, which will produce an average of 108 500 gold equivalent ounces a year over a ten-year mine life.
A contractor mining operating model is proposed for mine operations, tailings disposal and site support.
The project owner will operate the process plant, provide supervision for contractors, mine planning, ore control and general site administration. This hybrid owner/contractor model is used to leverage the regional mine contractor expertise and reduce initial project capital costs.
The current process flowsheet uses a one-stage crushing plant receiving run-of-mine ore and stacking crushed ore on a reclaim-feeder-equipped stockpile. The semiautogenous grinding mill is fed crushed ore at a nominal rate of 18 150 t/d and is in closed circuit with a ball mill, two pebble crushers and two banks of cyclones, which produces a product for flotation.
A flotation circuit, with regrind after rougher flotation, will produce a bulk flotation concentrate. Tailings will be thickened and dried using filter presses for dry stack disposal.
Opportunities exist to eliminate equipment and reduce capital cost through measures, such as the elimination of a pebble crusher and cyclone bank, as well as ball mills from the circuit, and the optimisation of the tailings preparation, resulting in less filtration.
