The first members of the staff sailed for Northern Nigeria on October 6,

and were followed a month later by Mr. Charles G. Lush, the well-known

expert on the working of alluvial tin deposits. Mr. Lush was to advise

as to the best method of developing the company’s property, which was

then stated to be 13 square miles in extent. Parenthetically it may be

mentioned that other suitable areas were afterwards taken up and several

handed over to subsidiary concerns. Mr. Lush first went to the Juga and

Sub-Juga properties, and the first communication received from him was

the following cable, dated Bauchi, December 17: “Have visited Juga, am

very favourably impressed. Up to the present time proved alluvial extends

over 200 acres and averages 9 feet; alluvial contains 4s. per cubic yard;

the value of stream tin, £600,000. I will visit Sub-Juga this week.” On

December 22 he again cabled as follows: “Sub-Juga—Have visited, am very

favourably impressed. I consider admirably adapted for the Australian

method of working. It will be necessary to erect a dam; will make survey

and report upon. Alluvial extends over 500 acres and averages 9 feet.

Estimated value of stream tin, 2s. 6d. per cubic yard.” From these and

other communications subsequently received it was evident that Mr. Lush

had been most favourably impressed with the field generally, and with the

value of the Champion Gold Reefs property in particular.

Four subsidiary companies have been formed to date, viz.:

Naraguta (Nigeria) Tin Mines, Ltd.

Lucky Chance Mines, Ltd.

Juga (Nigeria) Tin and Power Company, Ltd.

Tin Fields of Northern Nigeria, Ltd.

The Naraguta (Nigeria) Tin Mines is not only a productive concern, but

one that has already entered the dividend list, 1s. per share having been

distributed. The property was originally five square miles in extent, but

the area has since been extended. It was held under option by Champion

Gold Reefs, who transferred their option to the present company. The

purchase consideration paid to the Niger Company was £50,000, payable

as to £30,000 in cash and £20,000 in fully-paid shares. The Government

and the Niger Company are together entitled to a royalty of 10 per cent.

on the profits. Before the present company was formed the Niger Company

obtained from the Naraguta property over 1,000 tons of tin concentrates,

and it is stated that in one square mile of the property, which has

been systematically tested by pits, there are 10,000 tons of black tin

awaiting extraction. Up to the present time, the ground treated has

produced tin to the value of £3,000 per acre, whereas in other countries,

such as Australia and the Malay Peninsula, £1,000 per acre is considered

phenomenal. Some of the ground gives fully 5 lbs. of tin to the cubic

yard. There can be no doubt that Naraguta is going to be one of the

“gems” of the district.

The Lucky Chance Mines, Ltd., was originally formed in May, 1905, to

acquire property in New Zealand, but at the end of 1908 only seven shares

had been issued, and the paid-up capital was £5 5s., the company having

no assets or liabilities. Towards the end of last year, however, it was

placed on its financial legs by the Champion Gold Reefs of West Africa.

The latter company sold certain of its tin areas to the Lucky Chance

Company for 200,000 shares, and agreed to procure the subscription of

8,000 further shares. To-day the Lucky Chance Company is a robust and

ably-controlled enterprise, with excellent prospects of development.

Its properties comprise nearly 12,000 acres. The South Juga property

has recently been sold to the Juga (Nigeria) Tin and Power Company for

£10,000.

The Juga (Nigeria) Tin and Power Company owns what is known as the Juga

property, which is situated on a plateau 3,280 feet above sea-level,

having a total area of 1,600 acres, and the Sub-Juga property, which

lies upon the lower plateau immediately below Juga, the area in this

case being 6,720 acres. As already remarked, the South Juga property

has recently been added. Mr. Lush estimates that 200 acres of the Juga

property will be highly payable. For the purposes of his estimate, he

took the average depth as 9 feet, which, extending over 200 acres, equals

2,904,000 cubic yards, each cubic yard containing 6 lbs. “In valuing the

ground at 6 lbs. per cubic yard,” Mr. Lush said, “I am not taking into

account only the high results obtained from some of the bottom wash, but

am reckoning it as a whole. I do this because working results may prove

that the wash does not extend over the whole 200 acres, but the gravel

does, and I feel confident will average what I state.” In a similar way

he estimated that the Sub-Juga property would yield 3 lbs. per cubic yard

over 5,808,000 cubic yards.

Tin Fields of Northern Nigeria, Ltd., is a company owning eight square

miles at Federri and nine square miles near Dila River, both in the

Bauchi Province.

In addition to having floated these companies—in which, of course,

Champion Gold Reefs retains a large interest—the company has also large

holdings in the following concerns:

Northern Nigeria (Bauchi) Tin Mines.

Anglo-Continental Mines, Ltd.

Anchor Diamond Mines.

It also still owns a lease over five square miles in Ashanti.

NARAGUTA (NIGERIA) TIN MINES, LTD.

_Capital._—£175,000, divided into 175,000 shares of £1 each, of

which 158,500 are issued and fully paid.

_Directors._—Frank N. Best (Chairman), H. C. Godfray, Herbert

Moir, John Waddington, H. Bousquet, H. S. Reitlinger.

_Secretary._—Newman Ogle.

_Offices._—Friars House, New Broad Street, E.C.

This company owns an area of 3,200 acres at Naraguta, and two further

blocks known as the “C” and “Q” areas of eight square miles. It was

formerly worked by the Niger Company, who won from the alluvial beds

its 1,000 tons of tin concentrates. The company was registered on 15th

January, and the property was taken over on 4th February. Mr. C. G. Lush,

the company’s consulting engineer, has inspected the property, and has

stated that on the Naraguta property they had ground which would give

fully 5 lbs. of tin to the cubic yard. He further reported that ten

acres had already been treated and given that result, which could be

taken as a very fair prospecting whole.

The returns up to and including the month of October 1910 amounted to a

total of 350 tons of tin oxide made up as follows:

Good profits can be, and are being, made under the present primitive

methods in use, but the greatly increased profits to which the management

is looking forward can only be secured by adopting the most up-to-date

machinery, such as is used in Tasmania and other countries. In order to

assure success experienced men are being brought from Tasmania by the

Champion Gold Reefs group, and the Naraguta Company will have the benefit

of their advice.

At the statutory meeting in April last the chairman stated: “We have

the proud distinction of owning the property from which the first

shipments of tin were made—not only that, but one of the richest out

there, and I am quite confident this company can look forward to a very

successful career. The extent of our property is four square miles, one

mile only of which has been thoroughly prospected, and calculated to

contain 10,000 tons of tin oxide. At the present market price of tin

this should yield over £500,000 profit. Our engineer tells me that up to

the present time every acre of ground so far treated has produced tin to

the value of £3,000, whereas in other countries, such as Australia and

Malay, £1,000 per acre is considered phenomenal: therefore, I consider

we can congratulate ourselves upon being interested in such a unique

proposition.”

As an indication of what may be expected when improved working methods

have been introduced, Mr. 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 1½ 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; in fact, 10 acres have already been treated, and

have given that result, which can be taken as “a very fair prospecting

whole.” All that is necessary is to get the plant there as soon as

possible.

In Mr. Frank D. Bourke the company has an excellent and indefatigable

manager, and recently the directors engaged the services of Mr. A. F.

Kitto, who left on October 12 to assist Mr. Bourke in the management.

LUCKY CHANCE MINES, LTD.

_Capital._—£75,000 in 300,000 shares of 5s. each, all issued

and fully paid.

_Directors._—Mr. S. R. Bastard (Chairman), Mr. F. N. Best, and

Mr. Oliver Wethered.

_Secretary._—Mr. Newman Ogle.

_Offices._—Friars House, New Broad Street, E.C.

This company owns the following properties:—

(1) _Dubbo._—A property in Bauchi, Northern Nigeria, consisting of 632

acres. This property is under the charge of two engineers.

(2) _Rafinsiroma._—This is a small rich property of 33 acres adjoining

Dubbo to the south, and capable of immediately producing tin by ground

sluicing and calabashing.

(3) _Bengalili._—A property of about 320 acres on the river Bukeru,

situated about one mile to the north of Dubbo, and capable of producing

tin by handworking at once.

(4) _Bengalili North._—This is an area of about 120 acres adjoining and

to the north of the Bengalili property, also capable of producing tin by

sluicing and calabashing. The river runs through this property.

(5) _Polchi._—A property of 84 acres adjoining South Juga, and situated

on the main road from Toro to Bauchi. The property is now being worked

and is producing tin.

(6) _Boidun._—This property is situated on the road from Dubbo to Bri,

and is about one mile west of Dubbo. It extends for a distance of about a

mile along the river.

(7) _Bilidi River._—Three square miles, or 1,920 acres. Good tin was

found on this property, besides an appreciable amount of gold in the wash.

(8) _Kurdum._—Five square miles, or 3,200 acres. On the tests made the

overburden went 3 lbs. of tin for 7 feet, and the bottom wash went 60

lbs. of tin for 1 foot.

(9) _Kwall Falls._—The first application was made on behalf of this

company for this power, which would be of great value, as it gives 2,000

horse-power in the dry season, and commands several properties.

The _Dubbo_ property is situated near the village of Dubbo, on the Dubbo

River, and west of the Soli Hills. It is sometimes described as Topaz

Valley, so named on account of the large quantity of topaz found in the

wash. It is situated about six miles north of Juga. The Lireui natives

have done a lot of work on this property, sinking shafts in some cases a

hundred yards back from the Dubbo River. These shafts run from 8 to 10

feet in depth, proving that the bottom wash must have been very rich for,

as a rule, the Lireuis only mined shallow ground where the wash is easily

got. Mr. Lush said that he had not seen similar work in any other part of

the tin district.

Mr. Lush reported that the pannings from the river bed gave very high

values, and four shafts sunk to a depth of 8 feet averaged 6 lbs. of tin

to the cubic yard. One shaft, which bottomed at 5 feet, went 30 lbs. of

tin to the cubic yard. An open-cut on the river bank exposed 17 feet of

gravel, which went 6 lbs. to the cubic yard. The overburden thrown out at

the shafts sunk by the Lireuis, where tried, gave an average of 5 lbs. of

tin to the cubic yard. At the southern end of this property Mr. Lush says

the river comes down from a hill with a fall of some 350 feet through

a rocky gorge. By working a dam at the top of the rapids sufficient

water could be conserved to run a plant by electrical transmission. This

country is mostly granite sand, no stiff clay or pug. Mr. Lush states

that nearly the whole of the 632 acres are an alluvial deposit, and in

his estimates, in order to be well within the mark, he estimates that the

payable dirt extends over 300 acres and averages 6 feet in depth. The

manager reported on August 29 that he had 300 men employed, and for the

four weeks ending August 27 he had recovered 31½ tons of tin, and had cut

735 feet of water leads.

_Rafinsiroma_ adjoins Dubbo to the south, and the manager, reporting on

August 29, said he had just started work on this property. On September

4 the manager reported that he had already shipped 505 lbs., and a

cablegram received October 9 states that a further shipment is being

made.

Work has been started on Polchi, and on October 9 a cablegram was

received stating that the first shipment had been made.

On the _Bilidi River_ property Mr. Lush reported that he made several

tests from wash exposed on the river bank below the Kofai crossing, and

obtained payable tin results in all. He then followed up the river for

about three miles, and in one part he says he got gold as well as tin

in the concentrates. In five pannings he reports there were from six

to ten colours of gold in every dish, which in his opinion was highly

satisfactory. Two miles below the Kofai crossing he found some very

promising flats, where he also got eight colours of gold in one dish. At

the time of his visit he says there was sufficient water running in the

Bauchi River for centrifugal pump work.

As regards _Kurdum_ and _Dila Rivers_, at the lower end of the ground,

near the village of Bundas, Mr. Lush says he obtained very good prospects

of tin in gravel from the river bed. At Dawka, some eight miles upstream,

the wash taken out of the river went 80 lbs. to the cubic yard. Several

pits were sunk on the banks, but owing to soakage water only one

bottomed, the depth of which was 8 feet, and gave the following result:

Overburden 7 feet went 3 lbs. of tin to the cubic yard.

Bottom wash 1 foot went 60 lbs. of tin to the cubic yard.

The river between Dawka and Bundas falls 400 feet, and at the latter town

it is 30 feet by 2 feet deep, flowing at the rate of 60 feet per minute.

Even in the middle of the dry season Mr. Lush says a race cut from a

point about a mile upstream would give sufficient head to generate 500

h.p. by electricity.

Mr. L. H. L. Huddart, in his report on the Kurdum River concession, says

he feels justified in making a preliminary estimate in order to give an

idea of what the property may be proved to contain, and he bases it on

the following reasons:—

(_a_) The tin falls above the property.

(_b_) The river has its source in a country rich in tin.

(_c_) The good values obtained in the stream bed and samples

taken from the banks.

(_d_) The method of deposition of the alluvial which indicates

that “wash outs” are unlikely to be found. In fact some good

leads should have been left by the river in the older gravels.

Upon these grounds he is of opinion that there are about 300 acres of

alluvial ground that should prove to be about 2½ yards deep with values

of about 3 lbs. per cubic yard. Mr. Huddart adds that an output of about

30 tons per month, or 360 tons per year, should be reached without

difficulty. In conclusion, he says: “The property is a good one, and its

ample supply of water cannot be too strongly emphasised. Tin will be

produced quickly from the river bed, and systematic development should

bear out the above estimate, and enable the work to be laid out with a

view on ultimate production of about 40 tons per month.”

Application for the Kwall Falls for electric power has been made on

behalf of this company, and great importance is attached to them. They

are situated about 14 miles west of the Niger (Bauchi) Syndicate’s area,

and it is stated that in the driest months there is ample water flowing

with a drop of 400 feet to generate 2,000 h.p. without any expense of

damming.

TIN FIELDS OF NORTHERN NIGERIA, LTD.

This company owns alluvial tin property at Federri comprising an area of

5,120 acres, and a further property situated on the Dila River or Doss,

comprising an area of 5,760 acres.

On the Federri property a tin-bearing area of 300 acres has been proved

containing tin alluvial from 2½ to 3½ yards deep, going from 3 lbs. to 6

lbs. per cubic yard, and it is estimated that the property has a life of

twenty-six years.

The second property is the Dila River or Doss, which has a proved area

of tin alluvial deposit from 3 to 5 yards deep over 400 acres, with an

average value of 3 lbs. per cubic yard. The life of the property has been

estimated at twenty-three years. A fully qualified engineer is now in

charge of the properties, and production of tin is expected to commence

immediately. The consulting engineer is Mr. C. G. Lush.

JUGA (NIGERIA) TIN AND POWER COMPANY, LTD.

_Capital._—£275,000, in 275,000 £1 shares, of which all are

issued.

_Directors._—Sir J. West Ridgeway (Chairman), Mr. Segar Richard

Bastard, Mr. Frank Norman Best, Sir Horace G. Regnart, J.P.,

and Mr. Henry S. Reitlinger.

_Secretary._—Mr. Newman Ogle.

_Offices._—Friars House, New Broad Street, E.C.

This company owns three properties, as follows:—

Acres

(1) Juga 1600

(2) Sub-Juga 6720

(3) South Juga 1280

_South Juga._—Mr. C. G. Lush, in reporting on the South Juga property,

said: “On the northern end there are several native workings, in which

payable prospects can be got. It would be advisable to have shafts sunk

right along the lead from the Juga boundary to the Bauchi road, and

boring plant used if water hindered sinking to bed-rock.... Some of the

tin carried into Juga must have found its way into South Juga.” Mr. L.

H. L. Huddart, reporting on the property, said: “The elevation is about

3,000 feet above the sea-level, with precipitous granite hills rising at

least 1,500 feet above the valley on both sides.... The tin occurs in a

valley about four miles long, running north-east and south-west. Bed-rock

is granite with frequent outcrops of granite and granulite, which form

baths more or less at right angles to the valley. The average width is

about 2,000 feet.... The ground is friable and easy to work.... A water

course which rises on Juga runs right down to the valley. From December

to April there is practically no running water, but from May to November

the stream runs freely.... If the small tributaries are dammed, and skill

is used in saving the water, there should be sufficient for all purposes

for six or seven months in the year. Later on a portable pump elevating

plant would have sufficient water for at least nine months. There is a

considerable quantity of water held up between the granite baths, and the

water-locked ground provides natural reservoirs.... A thorough system

of prospecting should be inaugurated.... Pits should be put in right

across the valley at 100 feet intervals, and a property plan made out

showing the depth of ground valued. These will enable the mining work to

be laid out in a systematic manner, and will disclose the rich leads.”

Mr. Huddart has formed a favourable opinion of the property, and gives

the following reasons for the estimates he has prepared: (1) Amount

of work previously done by natives who never touch anything but rich

wash; (2) sampling and inspection of native working and their tailings;

(3) the fact that this proposition is geographically a part of Juga on

which rich wash exists; (4) personal knowledge of the ground tested and

discoveries on every known part of this field, and general occurrence of

cassiterite on all parts of the property. Taking the property as a whole,

he estimates that there are 180 acres of alluvial ground, running 4 lbs.

per cubic yard, averaging two yards deep. In conclusion, Mr. Huddart says

this is an attractive property.... Importance is readily attached to the

fact that the property can be made an immediate producer.

_Juga Property._—This property is on a plateau 3,280 feet above the

sea-level, and Mr. Lush estimates that 200 acres will be highly payable.

He takes the average depth of ground as 9 feet, and this extending for

200 acres equals 2,904,000 cubic yards. The area is of exceedingly high

quality, and exceptionally free from impurities. In his report Mr. Lush

says: “Valuing the ground at 6 lbs. per cubic yard, I am not taking into

account only the high results obtained from some of the bottom wash, but

am reckoning it as a whole. I do this because working results may prove

that the wash does not extend over the whole 200 acres, but the gravel

does, and I feel confident will average what I state.”

_Sub-Juga._—This property, comprising an area of 6,720 acres, lies upon

the lower plateau, or plain, immediately below Juga. The natives have

done a great deal of work here, and their beds were extensively tried

by Mr. Lush, who got very rich prospects when panning. Some of the dish

concentrates went as high as 40 lbs. of tin oxide to the cubic yard,

and in no single instance did he get less than 3 lbs. He considers that

out of the 6,720 acres 400 are proved to be highly payable, but this

only includes the main lead, which runs right through the property for

6¼ miles, and does not include any of the runs coming in from east and

west. He takes the average depth of ground as 9 feet; this extending for

400 acres equals 5,808,000 cubic yards. Mr. Lush has recommended movable

plants for these properties. Transmission of electrical power to run

both the nozzle and the gravel pumps is, of course, the cheapest and

best method of working, but it will be some time, probably two years,

before the contemplated hydraulical scheme can be installed. Mr. Lush’s

recommendations have been accepted by the board, and two plants are

being constructed, and their cost when mounted and erected at the mine

will not exceed £10,000. In addition to the sluice boxes at present

on the property, there are now on the way a further sixty-nine sluice

boxes, with all exhausters complete, and these will enable sluicing and

calabashing to be carried on pending the arrival and erection of the

hydraulic plant.

Mr. Hooke has been appointed manager, with Mr. Grant as his assistant.

Besides sluicing, surveys have to be completed, dams constructed,

prospecting done, especially by means of boring, tools being supplied for

those parts where the water is too heavy for the pits to be sunk.

Mr. A. W. Hooke writes under date September 14, 1910, as follows:

“Attached hereto are my notes upon the leases of the company and the

dam site. In setting forth this general report several difficulties

have faced the writer—the absence of any systematic sampling record—the

flooded condition of the existing holes, and the short time in which to

cover the ground.

“At the same time also an effort had to be made to organise the labour

and increase the output under existing circumstances. I give the

following summary to show how the output has increased in the last four

weeks. From August 15 to September 10 the production stands thus:

Week ending. Calabashers. Crude Purchased at

Tin Won.

August 20 52 men 768 lbs. ¾d. per lb.

” 27 102 ” 3,319 ” ¾d. ”

Sept. 3 127 ” 3,327 ” ¾d. ”

” 10 133 ” 4,925 ” ½d. ”

“Some of this ore is being won on Juga, but by far the greater part comes

from Nafuta. It contains much iron impurity, and a streaming box has

already been made for its re-treatment at Juga. It will be understood

that the natives bring their weekly winnings from Nafuta to Juga on

Sundays, when it is weighed and purchased from them. The first three lots

shown above were purchased approximately at ¾d. per lb., and the last one

at ½d. The condition of the tin, &c., is a big factor in guiding one as

to the price, but as time goes on I hope to instruct the native into the

way of streaming his tin and bringing it to a better quality. If I can do

this, and keep the price down, it means a big advantage to us.

“Labour at 6d. per day is most satisfactory (9d. is the ruling rate

elsewhere except at Dubbo). This week my whole gang struck work and

demanded an increase from 6d. to 9d. I flatly refused, and to time of

writing have almost as many new men as I require. Some of the old hands

have since returned to work. I have despatched a headman to Gingim and

Polchi, who will doubtless secure all that I require.
