The antimony recovery results also have minimal to no impact on gold recoveries, and are a key development in unlocking the substantial gold-antimony potential\n \n of Limo Butte.\n \n\n\n\n Key Highlights\n \n\n\n\n\n Positive Phase II antimony acid leaching results on\n \n antimony grades ranging from 0.1% Sb to 8.5% Sb\n \n including (Table 2):\n \n\n\n\n\n\n\n\n 0.13% Sb Sample achieved up to 85% recovery\n \n\n\n\n\n\n 0.17% Sb Sample achieved up to 71% recovery\n \n\n\n\n\n\n 0.59% Sb Sample achieved up to 66% recovery\n \n\n\n\n\n\n 2.09% Sb Sample achieved up to 71% recovery\n \n\n\n\n\n\n 4.67% Sb Sample achieved up to 92% recovery*\n \n\n\n\n\n\n 8.41% Sb Sample achieved up to 75% recovery*\n \n\n\n\n\n\n\n\n *Phase 1 results\n \n\n\n\n\n\n\n\n\n\n Acid Leaching is being reviewed as the preferred metallurgical process for antimony as there is currently\n \n no reliance on\n \n\n downstream processing at third-party smelters or refineries; the acid leaching scenario would produce antimony metal at site through a conventional leaching scenario\n \n\n\n\n\n\n\n Antimony leaching has many similarities to Solvent Extraction-Electrowinning (SX/EW) used for oxide copper in the copper industry\n \n\n\n\n\n\n Antimony recovery has\n \n minimal to no impact on the gold recovery\n \n in a potential combined gold-antimony mine scenario\n \n\n\n\n\n Drill program continues with 13 holes completed;\n \n the current phase of drilling is focused on advancing Limo Butte to a ...
