The fourth hill or mine is that of Antamog, which is perhaps more than two leguas from the said old fort and mine of Arisey, and five and one-half from our fort of Santiago, which faces south from a large hill whose peak extends east and west, the said elevation having been undermined by one of its springs, and traversed by very narrow small threads of white and yellow metal; while all the elevation is traversed by and filled with passages, which are found intermixed, opened sidewise from the vertical and inward, and dipping downward scarcely at all, as the threads of the metal are not deep. In order that these may not cave in, they are propped up with stakes and boards; for otherwise, inasmuch as the dirt is so loose, they would not remain at all secure, as has happened to those unpropped, since we saw some that were blocked up and caved in. The said works are very narrow, and all were examined without finding metal, because of the high level, or sides, or any kind of vein, except at the entrance of the openings whence they were drawn. From the said threads they obtained a kind of brass-colored and less dirty earth, in order to wash it in another large placer, that they had at one side of the said elevation, with a small stream that rises on top of the elevation, where they had a small settlement. They could, to all appearances, obtain but little profit, and with great difficulty, even with the community so near by. According to the signs, it was a long time since those workings and mines had been worked, and they were more neglected than the others; yet they produced the best (or the best-appearing) ore that could be found. Twenty baskets of it were obtained by the said miners to assay and investigate its nature, and determine what it might be. The fifth and last elevation, hill, or mine is that called Conog, which is about one-half legua from the preceding and located in the same chain. It is flooded by the sun all day long, as is the other. The said elevation, turning, extends toward the north. In it are to be seen five or six openings or passages, that differ but little from those of Antamog. No considerable or fundamental vein was found, but only brass-colored earth that contained some small bits of blue metal containing iron pyrites, all of them very soft. In one passage that was lower was found on the level a small stream of clear water which empties through another opening lower down than it, both of those openings having been made for one excavation. To all appearances those mines were abandoned long ago; and although they were not being worked, and were seen to be so neglected, they contained the best-appearing metal that was seen. The said miners got about ten small baskets of it to assay.
