The DSO Concentrate Model for QWN Open pits
Technology advances are transforming gold production options.
Imagine the capex savings by not needing a mill nor tailings facilities nor any of those asssociated infrastructure .
The example below coukd make such an option realistic for HD open pit mining.
All you need is a three stage crusher to reduce particle size and an XRAY Sorter.
Results from several trials shows that feed grades can be doubled, and 90% or more of the gold can be recoverid into a gold concentrade in the form of DSO ( Direct Shipped Ore ) directly to the smelter.
the mined out pit will be used for waste ore , eliminating the need for expensive tailings ponds ..
An example is shown in the link below...
Such a model would produce very high grade gold concentrate almost double the feed grade ,while the three stage crusher will be installed in H2.
Subsequently, once ramp up is settled away , the ore sorter is planned to be installed.
This will radically transform MAE and the HD deposits complex into a 100,000 ounce gold producer at total costs well less than $900 per ounce .
Quite likely, NFG will also this DSO model for its QWN pits.
