They hid all traces of emerald mining for 20 years, though in 1555 Luiz Lanchero founded the village of Muzo in their midst, incited, it seems, by the belief, based on rumor and more pointed information, that the nearby Itoco mountains had yielded the emerald in abundance.
In 1558 mining operations were begun by the Spaniards in these mountains and for a time actively prosecuted in the face of repeated attacks by the Indians.

This paper embodies the results of his observations, plus information personally communicated by Robert Scheibe, Professor of Geology in the Mining Academy of Berlin, who at the time of the visit was completing a detailed field investigation of nearly a year’s duration of the emerald deposits of Colombia.
D., Evanston, Illinois Transactions of the American Institute of Mining Engineers Vol. † Received June 28, 1916 The writer visited the Muzo emerald mines in July, 1915, and spent six days in their study.
The other localities indicated are prospects merely, though locally known as minas.
The total number of emerald localities in Boyaca has been stated to be 157, but this figure is probably a rough approximation.
The region in general is unhealthful; the natives suffer from tropical anaemia, malaria, dysentery, and other complaints incidental to the latitude.
The so-called Somondoco deposits (marked Chivor on the map) and those of Coscuez are important historically and enjoy the reputation of being very rich.Suffice to say that the Muzo mines were worked almost continuously during that period, but their development suffered from a lack of any sustained policy of administration as well as from the want of engineering and geological advice.In 1909, the Government closed a partnership contract with an English company, The Colombian Emerald Mining Co., Ltd., controlled by South African diamond interests,and the Government reassumed sole control of the mines.An elaborate account of this valuable work may be expected at a future date from the pen of Professor Scheibe. by trail west of the small village of Muzo in the Department of Boyaca, and embrace about eight great open cuts, closely grouped, occupying a portion of a steepwalled valley, that of the Itoco, also called Quebrada del Desaguadero, an affluent of Rio Minero which empties into the northward-flowing Magdalena, the great artery of commerce for central Colombia. from La Dorada, the head of steam navigation on the lower Magdalena, they are inaccessible from that point, and may be reached practicably only from Bogotá via rail to Cipaquira or Nemocon and thence by mule for 2 1/2 days over an execrable trail, nearly impassable in the rainy season (Fig. The region about the deposits is intensely tropical, characterized by excessive heat and high humidity, with a rank jungle growth that quickly obscures abandoned workings and makes exploration peculiarly difficult and costly.(60 miles ±) in a direct northwesterly line from Bogotá, the capital of Colombia (Fig. The region round about is sparsely inhabited by Indians who live in squalor and poverty — modified descendants of warlike aborigines, docile and peaceable, even servile, speaking a Spanish patois.

Work was later resumed but prosecuted only in a desultory fashion until the success of the War of Independence in 1819 transferred the holdings to the new-born Republic.
