_Quicksilver_. 10. Wednesday, the twenty-fourth of the said month of
April, four libras of quicksilver were incorporated with four quintals
of ore, obtained from a passage or opening carefully concealed in
the bed of the streamlet, almost at the end of the said vein, and at
the end of the other openings in it on the northwest side, where it
obtains but very little sun and considerable dampness. It is an ore
that contains a quantity of antimony, and one can obtain much of it,
to judge from the works that the Ygolotes had, and those that we were
making, as it seemed an ore of fairly good appearance. Compounding
the assay of the said four quintals with salt and magistral, [60] the
compound was washed on the second of May following, and a grain of gold
of one-half real weight obtained. Two onzas of quicksilver were lost.
_Quicksilver_. 11. On the twenty-ninth of April, three libras of
quicksilver were incorporated with three quintals of ore obtained
from a washing-place made by the Ygolotes below the openings, and near
the preceding place. The compound was washed on the fifth of May, and
a grain of gold weighing one and one-half reals was obtained. Eight
onzas of quicksilver were lost.
_Quicksilver_. 12. On the third of the said month of May, one libra
of quicksilver was incorporated with one quintal of ore obtained from
the said hole and vein as the four preceding assays. Having been
crushed and burned in the openings before being incorporated with
the said quicksilver, it was washed on the sixth; a small grain of
gold, weighing less than one-half real, was obtained from that assay,
while three onzas of quicksilver were lost.
_Quicksilver_. 13. April twenty-nine, one libra of quicksilver was
incorporated with one quintal of ore obtained from the old mines,
of which I have made mention, called Baranaban. On May sixteen it
was washed, and a small grain of gold obtained of one-quarter real
weight. Three onzas of quicksilver were lost.
_Arisus. Quicksilver._ 14. Tuesday, April thirty, one libra of
quicksilver was incorporated with another quintal of ore obtained
from the said old mines called Arisey and Bugayona. On May seven
following it was washed, and a small grain of gold, weighing less
than one-quarter real, obtained. Two and one-half onzas of quicksilver
were lost.
_Quicksilver_. 15. The first of the said month of May, one libra of
quicksilver was incorporated with one quintal of ore obtained from
the said old mines and from those called Antamo. On the eighth of the
said month it was washed, and a small grain of gold about as large
as the head of a pin, which could not be weighed, obtained. Six onzas
of quicksilver were lost.
