Abstract
[Resumen] En 1985, se trató una muestra tomada a mano y con casiterita visible, de un peso
de 1.028 Kg, procedente de una antigua labor abandonada a pocos metros del lavadero del grupo Minero «Boliches». Fue clasificada «de visu» como pegmatita, pero un estudio petrográfico posterior, la define como greisen, lo que, en principio, eleva el valor del indicio.
Por otra parte, el tratamiento de 90 t de zafras ha confirmado que la ley en estaño es alta.
[Abstract] In 1985, a sample weighing 1.029 Kg and with visible cassiterite, was obtained manually from an old abandoned work, few meters away from the buddle of «The Boliches Group», and it was treated. This sample was c1assified «de visu» as a pegmatite, but a later petrographic study defined it to be a greissen, that raises the value of this trace. On the other hand, the treatement of 90 tons of ores, has confumed that the content in tin is high.
