On one of the five elevations which I have said that the Ygolotes worked, namely, the said new one called Galan (it being the chief one, as I have said), I camped, and built the fort of Santiago, under whose advocacy [i.e., of Santiago or St. James] they say it was before.  Retaining with myself about two hundred natives from both provinces [i.e., Pampanga and Ilocos], with the Sangleys and prisoners whom I took with me, I sent back all the others with thirty soldiers on the twenty-eighth of the month of February, to get more provisions, ammunition, and other necessary things, at the village and storehouses of Arrimguey, although afterward some Ylocos Indians deserted in the one month and six days while I occupied that place, the natives having returned by a third path.  In all three months, their provisions amounted to two thousand and eighty-seven baskets of rice, each of fifteen gantas; and for the rations of all the men from January sixteen (when food began to be issued at my account) until March twenty-four following, were consumed two thousand and ninety-four baskets.  These rations were given to all the said natives, and to seven hundred and sixty others besides, who were brought from Ylocos by the said master-of-camp in order to exchange with the first, as has been said.  On the said day, March twenty-four, I mustered all the men, and paid and despatched them, except about one hundred and twenty from both provinces, thirty-one Sangleys, and about five adventurers [estravagantes] and substitutes who remained with me to aid and accompany us.

Having despatched the said men, I ordered the lieutenant of the province of Pagasinam not to advise me of anything unless it were a matter of great importance until the fifteenth of May, when he should send me four hundred other natives [from Pangasinan] and one hundred from the said province of Ylocos, all laden with beans and other things necessary for the sustenance of the men of the said presidio.  That was done in order that I might more freely attend to the investigation of the mines of the said Ygolotes and what substance they contained.  For that purpose I immediately ordered Martin de Vergara, my alferez, Rodrigo Lopez Orduna, Juan de Mugaburu, Graviel Molinero, and Diego de Tovar, soldiers of my company and all miners, and other persons who understood something [of mines] to investigate and reconnoiter the said new mines where the said Ygolotes were working.  The mouths of those mines are in the northern part [of the ridge], about a stone’s throw from the said fort, and the mine discovered extends from above downward in the manner of a horizontal vein or shell for the distance of a musket-shot from northwest to southeast, and then twists about for another equal distance to the direction that looks toward the northwest and west, until it disappears into the depths of a ravine or watercourse where there is but little sun.  That is not the case with the one that extends northwest and southeast, for it is flooded with sunlight most of the day.  When I reached that place the Ygolotes were working the said mines through many mouths or passages that they had opened, following the metal of one large vein, from which they were taking out the ore that was softest and easiest to dig, although it contained blue iron pyrites that contain antimony.
