Excerpt: ...ledges claiming to be silver-bearing of high grade ores were located during the past summer, but, like the gold prospects, have slipped away from the attention and have become completely eclipsed by the recent discoveries of tin, which gave rise to the next and more enduring excitement. Much has been claimed by the owners of the tin locations, the realization of one quarter of which would place it at the head of all the rich mineral discoveries made on this continent. That tin may be present to the amount of one, two or three per cent. is just possible, but there can be no doubt that the current reports of 70, 30, and even 15 per cent., are gross exaggerations. The actual presence of tin in most of the samples of so-called tin stone paraded about town is only presumptive, for assays and tests made by several of the most competent assayers of Salt Lake City show not even traces. _ It has been confidently affirmed by interested tin enthusiasts that specimens of mineral identical in character with those tested here, have yielded in the laboratories of able chemists in New York and Washington, as much as 30 and even 70 per cent. of tin. Such statements, however, cannot possibly deceive, as the simple test of gravity alone, will convince any one with ordinary experience in the handling of minerals, that but a low percentage of such a heavy metal as tin can possibly be contained in the vein stuff extracted from the claims in Weber district. It is further asserted that certain Cornishmen, professional adepts, have extracted from 15 to 18 per cent., by simply washing away the gangue, and fusing the concentrated stuff in the fire of a blacksmith's forge, while another expert of still more novel and inventive genius, reduces the ore and...
