Prior to 1926 Wells went into the Barkerville area on a prospecting trip. He was attracted to it by the knowledge that immense sums had been won from the creeks of that region in placer gold. His reasoning followed along the logical lines that since much of this gold was sharp-edged and contained fragments of quartz, without signs of having tray ‘elled far, it must originally have been deposited in veins which were once or still remained in the vieinity of the placer gold. The theory generally accepted at that time and which is only now being dis- pelled was that the gold of the Barkerville area had not travelled far, but that the veins in which it originally had been contained had eroded under elacial and weather action and that only the barren roots of these veins remained. Very wide quartz veins striking with the formation seemed to attest the truth of this theory, since they contained very low gold values despite their impressive widths and lateral strength. Several efforts had been made to mine them, but without success. Some of these failures may have been due to the less efficient metallurgical processes of other years, but in the main they were creditable to the fact that the wide ‘‘strike’’ veins, as they have since been described, were practically barren of gold values where explored. Where the cross fissure veins were opened ore was found but gold could not then be recovered from the sulphides. Wells was invited to look over the property on Cow Mountain where the Low- hee Creek company was placering in Lowhee Gulch and where Al Sanders and asso6ci- ates had done a small amount of surface work on some promising lode showings. On the mountain was a huge boulder of float quartz which was heavily impreg- nated with sulphides and which, sampled, returned good gold values. It was, even at that time, in the nature of a local landmark. Geologists expressed the opinion that it had been left there by a glacier. Wells left the Cariboo to carry on his prospecting elsewhere, but there was al- ways with him the continuing memory of that boulder of ore. Was it not reasonable, he argued, to presume that somew here in that vicinity there might be the vein from which the boulder came and that when it was found it would prove to be at least as wide as the narrowest width of the boulder? Good prospector that he was, Fred Wells could not rest easily until he had made another reconnaisance trip over that famous gold region and had followed that up with a detailed study of certain of the most interesting showings. It is to the everlasting credit of this rugged pioneer that he made discoveries which skilled engineers and geologists, with only one or two exceptions, had complete- ly overlooked and that he was not satisfied merely to make these observations and pass on. He remained to do something about his conclusions. Friends in Vancouver who had confidence in his judgment backed him financially to the limit of their ability and the Cariboo Gold Quartz Mining Company was formed to develop ground which he collected into a compact group on Cow, Island and Barkerville mountains. Briefly, the secret of Wells’ discovery, made coincidentally with, but without the assistance of the late Dr. W. L. Uglow, geologist, was that the wide and conspicu- ous strike veins running with the formation were not the probable sourees of Cariboo’s placer gold but rather the narrow and numerous cross fissure veins which struck across the formation and whose existence could seldom be detected on the surface, owing to erosion of the heavily-sulphided vein matter. He located them by panning on the hill- sides and then surface stripping. These obscure veins returned assays which were high enough to remove all doubt in Fred Wells’ mind that he had unlocked the seeret ‘of the Cariboo’ s lodes,
