The analysis of Sample No. 2 shows that the copper was almost without any deliberate alloying. The presence of iron, tin, lead and aluminium is evidently on account of impurities coming from the ore. No arsenic or antimony could be detected. On the other hand, Sample No. 1 showed the inclusions of tin to the extent of 11.68 per cent and lead and zinc 9.00 per cent and 6.28 per cent respectively.
