“ Laws, the mining industry has slowly forged ahead, until the rush came along this year. Year in, year out, I have been urging companies and encouraging prospectors to come along until I almost despaired of success; but now, given a railway to the tin field, the industry cannot but prosper if the Government do not hamper it with too many restrictions. ”

“ We know that there are considerable areas there which in some cases are very rich in alluvial tin. There are also tin lodes there; but that for the present is another story, because alluvial tin is a thing which is easily and comparatively inexpensively worked, whereas to work a lode mine requires good means of transport, and to be able to get up to the mines easily expensive and heavy machinery. We have a good climate, we have a sufficiency of water, and so far as we can ascertain, we have a sufficiency of native labour. ”

“ Climate.—Northern Nigeria is far different to any part of West Africa. You are at an elevation of some 500 feet. The nights are quite cool, and any man who takes ordinary care of himself and lives well ought to have good health. It is, in my opinion, by far and away the healthiest part of West Africa, and I say this after sixteen years spent in different parts of it.
“In conclusion, the results obtained prove conclusively [142] that there is immense alluvial wealth which can be cheaply won, and I believe in this property you have one which will prove an astonishing success. ”

“ There is not the slightest doubt that before very long many of the deep alluvial flats that are some distance from the shallow and more easily worked tin ground will be worked. The values may turn out to be poorer than the shallow ground, but the natural facilities are better owing to the water supply being sufficient for continuous working without the expense of erection of dams. On the other hand, when you get out of the [24] granite country, the further you are away from the source of the tin the greater are the impurities mixed with it. ”

“ There is a great deal of pioneering work to be done, and what we have still to look forward to is steady systematic organisation for the next year or two. We do not want to make the mistakes that have been made in the opening up of many new countries—some of them not very far from Nigeria—but we do want to settle down to steady systematic development. As far as the railway is concerned, there seems no doubt that we shall have a line into the tin fields, which is going to simplify the question of transport, and reduce the costs very materially. ”

“ I can form no idea as to the depths of the tin-bearing soil, as on the western boundary I have reached 35 feet in depth without getting to the end, on the eastern boundary about 30 feet in depth. You have over the whole of your area alluvial deposits existing on a very large scale. These deposits yield cassiterite (tin oxide) containing on an average 62 per cent. metallic tin, which proves the alluvial to be as rich or even richer than you find in any other part of the world.
“I estimate the yield at 7 lbs. per cubic yard—equal to, say, 5 s. per cubic yard, with tin oxide at £85 per ton. ”

“ 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. ”

“ The markets and trading stations of the Niger Company were within its boundaries, the fertility of the soil was proved, its richness in rubber, tobacco, and coal was established, and its wealth of other vegetable products was well known. It is not at all surprising, then, that British pioneers and capitalists saw the splendid commercial future that was before Southern Nigeria, and were somewhat neglectful of the distant, isolated, and inaccessible Northern territories. ”

“ The Niger Company have practically controlled the country, and have perfected arrangements by which they can supply large numbers of natives for carrying goods from the river to the tin field, but on several occasions their organisation has been interfered with by persons offering the natives three or four times their usual pay in order to get them through quickly to the fields. This, of course, as will be seen, is a dangerous policy, for if a scale is not strictly adhered to, the time will come when the natives will start attempting to dictate their own terms. ”

“ As would be expected from the nature of the ground, the top gravels do not carry payable values, but it seems to me almost impossible for the bottom to be other than rich when it is remembered that tin will not travel far without easy outlet and good grades, and that for a long period tin-bearing dirt has been emptying itself into this basin from so many channels. We have been unable to reach bottom in ordinary trial pits owing to heavy water and the running nature of the alluvial, and it will now have to be tested by boring. ”

“ The concensus of opinions held by men who understand the amount and nature of the work entailed in this particular form of mining, and are, at the same time, personally familiar with the material that the country has to offer for the purpose, shows that the supply of labour in Northern Nigeria is entirely adequate, and although the development of West Africa depends almost entirely upon the labour question, there is no prospect of any difficulty on this account. ”

“ There is always something to go away with. Mr. Lush, in a report which he gave us at the time of the flotation of this mine, estimated that we could reckon upon having 500 acres containing 2 lbs. of tin per cubic yard, and if that estimate is realised—and I have no reason to anticipate that it will not be realised—and the profits are made that he foreshadowed might be made, you have a very handsome property, and one containing apparently something over half a million sterling worth of tin. ”

“ C. G. Lush states that thirty men and one plant will be able to produce as much and even more tin than is now being obtained with three hundred men. “If we put only one plant on the property,” he says, “it will take us, perhaps, a hundred years to work it out, but there is no reason why we should not have four or five plants, and work it out in a lifetime!” In Australia, Tasmania, and the Straits Settlements [80] 11⁄2 lbs. of tin per cubic yard is considered very good, but Mr. Lush is of opinion that in Naraguta the ground will give fully 5 lbs. of tin per cubic yard ”

“ 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. ”

“ Everybody believes the tin deposits to be very rich, and if only half the reports concerning them are true, there is more than enough to warrant the expenditure of making a branch to the tin fields of the Province of Bauchi. This would give direct access from the sea at Lagos to the tin fields. The reports show that the tin alluvial is similar to that of the Malay Peninsula, which produces more than half the tin of the world. ”

“ Lush, writing on the subject of the cost of living and provisions, says “living is cheap, there being plenty of beef, mutton, fowls, milk, eggs, &c. Any kind of vegetable grows well, especially English varieties; in fact very few mining fields that I have visited can be compared to Northern Nigeria in respect of the various sorts of wholesome fresh food that can be obtained. In fact all one requires is flour and a few groceries. ”

“ Even under existing conditions alluvial tin mining in Nigeria is a highly profitable business, but when the present railway system is completed, and the road made from the Government line to the tin field, the freight should be reduced by many pounds per ton, and the profit largely increased. The completion of the road would enable heavy machinery to be brought to the mines, when larger quantities of the rich alluvial ground would be handled in an economical way, and the work done at a cost much below what is possible under existing conditions. ”

“ The cultivation of food stuffs has increased; new markets have been established, and the present safety of the roads has greatly stimulated the internal trade of the country. A great improvement in the export trade has followed the extension of the Baro-Kano Railway. To the north of Minna there is a most extensive area of shea butter trees, but very little of the [68] produce of this area has so far been placed on the market, partly on account of the cost of transport, and partly owing to the reluctance of the pagans to have intercourse with markets outside their districts. ”

“ At first it was considered that the formation of a good road from Bauchi to strike the Baro-Kano line about Zaria would suffice for the needs of the field, but the extraordinary extent and richness of the deposits, and the phenomenal success achieved by the Naraguta (Nigeria) Tin Mines, Ltd., the Lucky Chance Mines, Ltd., and other companies at work there, emphasised the self-evident fact that nothing less than a branch railway would be [37] sufficient to adequately develop the new industry. ”

“ 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. ”

“ The Niger Company continued to win mineral, and the Mineral Survey persisted in their efforts to prove the extent of country over which the granites were tin bearing. It is possible that the remoteness and inaccessibility of the Protectorate operated unfavourably in the minds of mining adventurers, and the evil reputation which had been erroneously given to the country may have moved financiers to an excess of cautiousness. ”

“ During the last few years they have opened up the Bauchi tin field in Northern Nigeria, and their trading and transport facilities have made it possible for them to carry out an enormous amount of development under great difficulties. The directors have had the courage of their convictions. In forwarding their own interests they have benefited the Protectorate, and if they have profited by their enterprise they have made the country a source of profit for others. ”

“ Nature of the Wash.—In the upper end the wash is a fine whitish granite, containing no large pebbles or boulders, and is near the original source of some of the Juga tin. The surface is slightly cemented with iron oxides in which cassiterite often grows. The whole wash very easily breaks down with water. The ground further down the property is similar except that [25] the alluvial has travelled further, and consequently has been sorted to a greater extent. ”

“ The actual value and life of only the area I have reported upon would, in my opinion, quite justify your proceeding with vigorous development work at once. The probable values of the remaining 30 square miles may possibly turn out equal to the southern; there is no reason why they should not, as the whole of the property is within a rich alluvial [110] and lode tin district that has hardly as yet been scratched. ”

“ Reporting on a property at Juga in the tin district, Mr. Huddart says:
“The properties are very favourably situated to obtain labour. The men from Bauchi and the east come along the main caravan route looking for work to enable them to earn money to pay the taxes, &c. As this particular property is near the market, and the men usually halt at the market, they can easily be recruited. The cost of ordinary labour is 1d. per hour, and is easily trained. The Bornu and Eastern Kanuri are, in my opinion, the best workers available. ”

“ In any case where tailings or any other products whatever from the operations of mining or metallurgy are being discharged, or about to be discharged, in such a manner as to hinder or injuriously affect any other person in the execution of his legal mining rights, or the future development of mining, it shall be lawful for the Government Inspector of Mines to order the disposal of such products or tailings in some other manner not detrimental to present or future mining. ”

“ Parkinson states that in the Oban Hills, Southern Nigeria, there are tourmaline pegmatites, and Schmeisser has recorded that since the discovery of an apparently rich tin deposit near Banyo, there has been much prospecting for that mineral in the Cameroons. Surface tin is found in Northern Nigeria by the natives, and sold, chiefly to the Niger Company, but mines on a large scale have not as yet been worked. The geological surveyors sent out by the Imperial Institute have detected the presence of alluvial tin in many sand and river gravels. ”
