The Golden Eagle vein is roughly parallel to the Comet and from 1,000 to 1,500 feet to the west. In the gulch an irregular quartz vein has been developed to some extent.
The Golden Eagle mine was inaccessible at the time of visit. The vein, known as the Golden Arrow, follows a fault of comparatively small throw and strikes about N. 20° W. at the mine but swings to the northwest a short distance to the north. The dip is 67° E. at the mine but is steeper a short distance to the north, on the ridge. At the mine both walls are in the Last Chance andesite, but in the gulch a few feet to the north the Cooney quartz latite comes in on the footwall. A short distance to the south the Fanney rhyolite occurs on the hanging-wall side. Scott says that the mine is interesting chiefly on account of the predominance of gold, which constitutes 70 per cent of the total value, the ratio of silver to gold being only 9 to 1 by weight. If this statement refers to oxidized ore it might point to the possibility of silver enrichment in depth. The material on the dump shows quartz with numerous andesite fragments, here carrying considerable pyrite, in part oxidized to limonite. Along the gulch the vein is concealed, and on the ridge it shows only as a shear zone in andesitic agglomerate with very little quartz. The dump of the closed tunnel on the north side of the ridge shows vein material consisting of small veinlets of porcelain-like and drusy quartz, cutting and to a slight extent replacing the Cooney quartz latite. No vein was seen on the surface northward from this point.
