More than half of the copper in the ore was recovered by jigging in each test. Relatively large pieces of native copper were not present in this ore, as jig concentrates contained only 0.2% by weight plus 5/8-inch material. The Mineral jig yielded a concentrate assaying 74.6% Cu in test B and a concentrate assaying 65.5% Cu in test A.
