The bonanza mines are situated in the northeast part of Virginia City, and many buildings stand on the ground under which they lie. Small bodies of paying ore were found in some of the mines composing the California mine in the early days, but they were soon worked out, and for a number of years the ground lay idle. In the Dick Sides and White & Murphy, the two mines from which was formed the Consolidated Virginia, very little ore of any kind was found on the surface or even at the depth of three or[or] four hundred feet, and these claims had also lain idle several years before they were purchased by Messrs Mackey & Fair and their associates Messrs Flood & O’Brien, of San Francisco. However, on what is now the Consolidated Virginia ground, a shaft had been sunk to the depth of six or seven hundred feet from the bottom of which had been run a drift of considerable length.

Ore was first found in the Consolidated Virginia, in March, 1873 at the time when Captain S. T. Curtis (in 1875 superintendent of the Ophir) was in charge. The ore then found was a body about twelve feet in width, which was encountered at the depth of 1,167 feet below the surface in a drift run from the corresponding level of the Gould & Curry mine. At the same time two other bodies of ore—the largest seven feet in width—were found, which yielded assays averaging $60 per ton. At this time their present main shaft was down 710 feet, and was being sunk at the rate of three feet per day.

In October, 1873, the main shaft had reached the 1,167-foot level and in drifting southeasterly a distance of 250 feet a very rich deposit of ore was reached—the top of the big bonanza, in[in] fact. The work of breasting out and regularly extracting ore from this body was commenced October 16, and by the 29th a chamber had been opened in it from six to nine sets of timbers in width (the sets are five feet apart each way) and four floors or sets in height, with solid masses of ore in sight on all sides. A drift had then been run lengthwise through the ore a distance of one hundred and forty feet, while the nine sets of timbers showed it to be fifty-four feet in width. Although all this wealth was in sight in the mine, the people of the town, walking over and around the mine knew nothing of it. What was in the mine was only known to those at work there, and to the officers of the company. I had the satisfaction of being the first “outsider” to descend into the mine and inspect the deposit in regard to which—the mine being closed to visitors—there had been a thousand surmises, favorable and unfavorable. I took samples from all parts of the ore-body and had them assayed. The highest assay obtained was $632,63 per ton, and the lowest, $93,67,—seven samples being tested. Thus it will be seen that even the top of the bonanza was wonderfully rich.

The company continued to explore this body of ore in all directions, running drifts and cross-cuts through it, sinking winzes upon it and making upraises. They followed it down to the 1200, the 1300, 1400 and to the 1500-foot levels, with the same rich ore everywhere. Although people knew in a general way that there was an abundance of rich ore in the mine, they did not get excited about it, nor did they trouble themselves much about it in any way, further, perhaps, than to say: “Well, I am glad to hear that the Consolidated folks have a big body of ore; it will be a good thing for the town.” The mine did not attract more attention than many others, until in October 1874, when the work of opening out on the 1500-foot level was begun. The ore then found was of such extraordinary richness, and the ore-body appeared to be of such unprecedented extent that people began to talk about it, and then some few began to visit and examine it, all coming to the surface greatly astonished at what they had seen. The reports in regard to the great wealth in sight in the mine, brought to the people of the upper world by scores of reliable men and capable mining experts, soon caused not a little excitement, and everywhere in the streets persons were to be heard talking of the wonderful wealth that was being developed in the Consolidated Virginia mine. Day after day the excitement grew as the reports came from the visitors to the mine that the cross-cuts had been advanced fifty feet, seventy-five, then one hundred feet into the big bonanza and still no signs of getting through it were seen. The cross-cuts still contained in a solid mass of ore of the richest description and each day found them advancing in the same, even after they had gone one hundred and fifty and two hundred feet.

At this time no cross-cuts had been made into the California ground, but the most northerly cross-cut in the Consolidated Virginia was but a few feet from the California south line, therefore this would serve very well to test that portion of both mines. All who comprehended the situation being now confident that the great body of ore which was slowly being explored in the Consolidated Virginia must extend far northward into the ground of the California Company, the stock of said company was soon in brisk demand. As drifts extended southward from the Ophir mine into the California and they encountered rich ore in two or three places, it was considered certain that a mass of ore extended all the way from the Consolidated Virginia to the mine first named, a distance of six hundred feet. Although the stock of the California was but $30 or $40 per share in the beginning, it finally reached $750, for the old shares—afterwards increased five for one.

At this time, although there were no cross-cuts in the California section of the bonanza, there was a main north and south drift extending from the Consolidated Virginia mine to the Ophir, through the west-country rock, and, from this, cross-cuts had been started, and at no distant day reached the ore.

As the progress of these cross-cuts in the rich ore of the bonanza was made known from time to time the excitement gradually increased until it reached fever heat, both in Virginia City and San Francisco. Never were the people more fairly treated on the occasion of any big strike on the Comstock lode than they were by the Consolidated Virginia and California Companies during the time the big bonanza was being opened and explored. All who desired to do so were allowed to descend into the mines and see for themselves what was being done. Often there were such crowds of visitors as to very seriously interfere with all underground operations. There were times when for days together the miners did not do more than two or three hours work on a shift, so frequent were the interruptions caused by persons visiting the drifts and cross-cuts that had penetrated the ore-body. One party had no sooner been shown through the two mines than another arrived. All were allowed to dig into and examine the ore, to carry away samples for assays, and, in short, to try whatever experiments they chose in order to satisfy themselves in regard to the value of the deposit.

The men who visited the lower levels and made themselves most familiar with the developments thereon, were the men who purchased more freely, and those who were experts in mining matters were those who were most astounded at the great richness and vast extent of the body of ore opened into. These men bought on their judgement while the mercurial masses bought at random, and under the influence of contact with persons as much and as blindly excited as they themselves were.[were.]
