Antimony Ores
Antimony Ores.
Carrick Range.
These samples from Carrick were forwarded by Mr. Buchan, and were found to contain 50 to 54 per cent. of antimony. The ore of this quality is too far in the interior of the country to be exported profitably. With good fuel, however, it might be freed from the earthy matters with which it is associated, and then conveyed to Dunedin for transmission to Melbourne, where there are, I believe, large works for the reduction of this ore (stibnite) to the metallic state.
Miller’s Flat.
This sample of stibnite was sent from Miller’s Flat by Mr. J. A. Grant in September, 1873. It was found to contain 58 per cent. of metallic antmony, but the sample examined was too small to be taken as an average of the bulk of ore.
Arrow.
This sample, forwarded through A. Willis, Esq., from Arrowtown. It contains 34 per cent. of metal, aud is therefore too poor to work profitably.
