Challenger Gold announced the results of its latest metallurgical tests, which highlighted a promising method of upgrading gold and silver concentrate at the Hualilan Gold Project.
The test compared two different grind sizes of high intensity leaches.
The results indicate a clear and simple method of producing gold doré on-site, significantly improving existing transport and treatment costs while increasing the payability of the gold produced.
Initial tests are the first in a series targeting several potential opportunities to improve the Hualilan scoping study's economics further.
