“The width of the property (three-quarters of a mile) does not include the whole of the large alluvial flats that occur on either side of the river, but having secured the river and so much of the adjacent ground, these flats are protected, and, if necessary, may be taken up when the land for mining purposes is selected.
“Of the area staked, certainly more than two-thirds carries alluvial ground of the thickness given above. Except in the bed of the stream, I would not expect rich patches, but a fairly uniform value throughout.
Water.—There is a continuous flow of water for sluicing purposes all the year round.
Grades.—Cannot be determined without survey, but at the lower (Forum) end of the property there is sufficient fall to allow the tailings to be inexpensively dealt with.
Costs.—Will compare favourably with other mines in the district, i.e. with ground of moderate value the costs would amount to between £10 and £15 per ton of black tin, and present transport charges £27 10s. per ton inclusive.
“Final tests of the flats are capable of being cheaply and quickly carried out by means of trial pits; boring is unnecessary. The probability is that the workable ground will prove to be of too large an area to be included in one mining lease, and that it will be necessary to split the present area into two or more properties.”
New Mining Regulations for Northern Nigeria
[Note.—The Proclamation as enacted in the Protectorate differs from this copy in the addition of a clause suspending—as regards licences to mine issued under the previous Proclamation—the operation of Section 26 and Regulation 23 (relating to royalties) until 1st January 1911, to which date the provisions of the “Minerals Proclamation, 1902,” with regard to duty on profits, are kept in force.]
