Nigeria and its tin fields

by Albert Frederick Calvert

THE FUTURE OF THE FIELD

The published opinions of Government officials, engineers of repute, capitalists, traders, and travellers, all tend to prove that in Northern Nigeria we have one of the largest, if not the very largest, of the tin-producing areas of the world. Other minerals are known to exist, and very big developments may be looked for in the near future, as the pioneering efforts of the Niger Company and the Champion Gold Reefs of West Africa are being followed by powerful financial houses, but alluvial tin stands out, and will always stand out, as the leading product of this remarkable mineral country.

Two such astute men and persons so well acquainted with the country as Sir Walter Egerton, the Governor of Southern Nigeria, and the late Sir Alfred Jones, have expressed the strongest views as to the extent and importance of these tin deposits, and the acting Governor of Northern Nigeria in his latest report asserted that “with the introduction of more capital and a good means of transport from the field to the railway a very large development is anticipated.”

Mr. Lush says the Bauchi tin deposits are richer than he has seen in any part of the world. It is, he says, a granite country, and although the existence of reefs has been proved in one part of the district, the alluvial deposits—which yield tin oxide containing about 72 per cent. of metallic tin—are of principal importance.

ALLUVIAL AND LODE MINING

Alluvial mining, has, of course, the demerit of being short-lived. There is no great depth in the deposits, and especially if they are worked economically—that is to say rapidly—they are exhausted in a comparatively short time. But the attention directed to the district in these alluvial workings will certainly lead to the discovery and opening-up of the tin lodes, which in course of time should prove a more lasting source of supply than the alluvials. Indeed, at two points, two tin lodes are already being opened up, and before long a good idea should be obtained of their value. The interests at work in the district will certainly see that every chance is given to this side of the business, but, of course, development upon a lode is very different work to that upon alluvial deposits, and progress may be slower in their case. It is very unlikely, with such an enormous area of stanniferous gravels, that lodes of importance should not be discovered as time goes on, and there appears to be no doubt that the tin production of Nigeria will become quite a factor in the markets of the world. Many things will have to happen before lode producing can be carried out upon a large scale, but as the alluvials are worked out, the labour employed upon them can be concentrated upon the most lasting deposits, and the operations of the alluvial miners should produce a working population which should be fitted to deal with the higher form of mining. Certain facilities will doubtless be given to the district, and some idea of the importance and the developments in this part of Nigeria can be gathered from the fact that the Bank of British West Africa has been earnestly invited to open an office in Bauchi. At present this matter is under consideration, since it is difficult to fix upon a spot which will be most suitable for such an institution to work, but before long it is probable that the tin-mining district will have the facilities offered by a bank.

THE GENERAL PROSPECTS

Mr. Oliver Wethered, whose name is so well known in connection with the tin industry, has described to a meeting of shareholders the peculiar advantages of the country which is now attracting the attention of the tin markets of the world, and in the course of his address he said:

“Now as to the country in which our interests are centred, judging by the information that I have received from all available quarters, I have no hesitation in stating that we are interested in one of the most important virgin alluvial tin fields the world has ever seen, and certainly the most important that capitalists have had an opportunity of working as a new field. In Tasmania, Australia, and other countries which have produced large quantities of alluvial tin, the prospectors have gone in by hundreds, and even thousands, and have washed out large quantities of tin greatly to their own individual benefit. Subsequently the ground has been worked over and over again, and in recent years again re-worked by means of modern appliances. I may say here, that in Cornwall some of the ground must have been worked eight or ten times, and big plants are now being erected for the purpose of working it again by modern methods. It will be obvious to every one that with a practically untouched field, and working in the most economical and thorough way from the start, the results cannot fail to be extremely satisfactory.
