This wall may be a continuation of the Akankon formation; both are rich in
a highly crystalline quartz of livid blue, apparently the best colour
throughout the Gold Region. The surface-ground, of yellowish marl with
quartz-pebbles, is evidently auriferous, and below it lies a harder red
earth rusty with iron. From the southern boundary of the Inyoko
concession, and the village of that name, runs a strong outcrop of a
kindly white quartz, which, when occurring in conjunction with the blue,
usually denotes that both are richer than when a single colour is found.
Such at least is Cameron's experience.
Mr. Walker, who secured this concession also, notes that the native pits
were very shallow and superficial. He was pressed for time, and sunk his
trial-shaft but little more than three fathoms: here free gold was visible
in the blue quartz, which yielded upwards of one ounce per ton.
My companion found the shaft still open, and observed that the valley
contained many holes and washing-pits. One was pointed out to him by Mr.
