The Discovery of Iron Ore at Conisborough
The boring operations which have been undertaken on Lord Conyers estate at Conisborough, with the object of ascertaining the extent and quality of the ironstone bed recently discovered there, have been seriously impeded in the past few days owing to the heavy rains.
As the question as to whether a valuable mineral lies under the surface and exercise the minds of local geologists and engineers for some time back. The discolouration of the stream that passes through their state was a circumstance which first suggested the presence of iron or in the locality. Three years ago the matter exciting a good deal of interest, but for some reason or other the investigations were not pursued. In the meantime, strong evidence of the existence of the your has been forthcoming, and the local engineer, Mr Warburton, as in his possession some good specimens that had been dug up.
In order, however, that the matter may be fully tested, Lord Conyers, has caused boring operations to be commenced. Two shafts have already been sunk and the third began, and though it is yet too early to form anything like an accurate opinion as to the value of the discovery, the results of the experiments, as far as they go, are regarded as promising.
