In mining news, it is all about Western Copper and Gold. The Canadian company is in the midst of assessing a resource at its Casino project in the Yukon. It is hoping for a larger resource than expected.
An older feasibility study in 2013 planned for a mill and heap leaching to access the copper, gold, silver and molybdenum found at Casino. Now, with a PEA (preliminary economic assessment), Western Copper can more than double the size of the Casino deposit. A new feasibility study based on the PEA is at hand, slated for mid-2021.
Mining means statistics and here they are: Casino enjoys 2.17 billion metric tons of millable measured and indicated resources with an average of 0.16% (7.43 billion pounds) copper, 0.18 grams per metric ton (12.7 million ounces) gold, 1.4 g/t (100.2 million oz) silver, and 0.017% (811.6 million lbs.) molybdenum.
There is more. It hosts 1.43 billion metric tons of millable inferred resource averaging 0..1% (3.24 billion lb.) copper, 0.14 g/t (6.4 million oz) gold, 1.2 g/t (53.5 million oz) silver, and 0.01% (322.8 million lb.) molybdenum.
What this all indicates is a nice 106% increase in the millable measured and indicate tonnage over an original estimated 2010 resource.
The amount of copper and gold is now greater by 3.3 billion lbs. and 6.6 million oz, respectively.
Also going up from the 2010 estimate are the measured and indicated heap leach resources at Casino. Now it is assumed to be 217.4 million metric tons, averaging 0.03% (166.5 million lbs.) copper, 0.25 g/t (1.8 million oz) gold, and 1.9 g/t (13.3 million oz.) silver.
According to Western Copper and Gold President and CEO Paul West-Sells, by more than doubling the measured and indicated mill resource, the Casino project is clearly one of the largest copper-gold projects in the world.
“This resource and the results of this year’s drilling program
will be incorporated in an updated feasibility study in the future.”
The PEA is focusing on a large open-pit mine feeding sulfide ore to a mill and oxide ore to a heap leach facility in order to recover gold, silver, and copper. Positive outcomes are expected to enable Western Copper to start plans for engineering, field investigations, test work, permitting and community relations activities for the project.
“A PEA will allow the company to quickly assess changes to the
project and outline updated economic returns of the Casino
project before launching a full updated feasibility study.”
