January 10 1897: “W. H Shin who has lately established a law office at Randsburg, in speaking of the remarkable mines of that district said yesterday.
“I recently bought for $19,000 the Monkey Wrench, Big Wedge, and J. I. C. claims which lie over the mother lode. The Kenyon people are working within fifty feet of the boundary ling of the J. I C. and the Little Wedge within seventy feet.” – Los Angeles Daily Times
January 17, 1897: “The J I C claim, lying contiguous to the Butte mine, is attracting a good deal of attention from mining men who are investigating the district, and presents a most promising opportunity to the investor because of its location. — San Francisco Call
March 6, 1897: “LAST EVENING THE CAMP was busily engaged discussing the sale of the Excelsior, J.I.C., and the “Big Wedge” claims, the Barton brothers, Ragsdale, Frigard and others interested were the recipients of many a heartfelt handshake and congratulation from well-wishers. It was a little premature, but as every one of the eight men and one lady who held an interest, had arrived at an amicable agreement to be on hand today and carry out their part of the agreement to the transfer of the three claims, the wall wishes were not out of order.
J. J. Brown and J. A. Shinn of Colorado, were the purchasers and the price paid was $30,000 cash. A force of men will be put to work at once. Two shafts will be sunk, one on the Excelsior and the other on the J.I. C. From time to time additional men will be put on, and machinery will be added, as soon as necessity requires it. Messrs. Shinn and Brown arrived her about three months ago and soon purchased several prospects, thereby identifying themselves with the camp and district. Next their attention was attracted to the above-named group situated east of the Rand, near the Kenyon, Little Wedge, and Butte, the leading paying mines of the district.
While there is not pay ore on the surface at present, they expect to open the chute of ore now existing in the Little Wedge, (the mine lately incorporated by Pepper, Rodgers and Allen) and possibly other ore chutes, as the Excelsior and J.I. C. embrace over 1200 feet of the same vein. Probably this will be one of the greatest enterprises started in the camp for some time, and will be of the greatest benefit, not only to the district, but to all the desert mines, for both men are well known as practical miners.” – Los Angeles Daily Times
March 14, 1897: “J. J. BROWN AND J. A. SHINN, the Colorado men who have been here all winter, leave today for Los Angeles and Denver. These are the parties who have bonded the J.I.C., Excelsior, and Big Wedge claims for $31,000. They expect to return in three weeks. While they are gone a force of men will sink shafts on the Excelsior and the J.I.C. these are valuable mines, located in a rich neighborhood near other producing mines and may prove even more valuable. R. R. Ripley of Leadville, will have charge of the work in the absence of Messrs. Brown and Shinn.” – Los Angeles Daily Times
April 22, 1897: “MR. RIPLEY, who has charge of Brown & Shinn’s business in their absence, is pushing the work of sinking on both the J. I. C., and the Excelsior. They are down 75 feet on one and 90 feet on the other, with good indications on both. These mines lie on the hillside just north of the Kenyon, Wedge, and Butte. They are employing fifteen men, and have a hoist on the Excelsior, and are putting one on the J. I. C.” – Los Angeles Daily Times
July 11, 1897: “.EXCELSIOR AND J. I. C. — The above two named claims, together with the Big Wedge, which adjoins the J. I. C. on its north line, form a group of mines extending from the Monkey Wrench on the west to the Butte on the east, and lie just north of the Butte. They belong to J. J. Brown of Denver, and Col. James A. Shinn of leadville. The former is one of the principal owners of the famous Little Johnnie mine at Leadville, one of the biggest paying mining propositions ever unearthed in Colorado and which is still paying enormous profits. Col. Shinn, who is one of the best known mining men of Colorado, came here with Mr. Brown last December, an after having made a pretty thorough examination of the district they purchased a number of claims which besides the three mentioned above, include The Tom, White Hills, White House, Philadelphia, Serpent of the Desert, and the Rattlesnake. After some deliberation they finally selected the Excelsior, the J. I. C. and the Big Wedge, which adjoin each other, as the particular ones for extensive operations. They began work early March by sinking a four by eight double compartment shaft of the J. I. C. This shaft if now down 192 feet, timbered and partitioned all the way, with a ladder in place and a roomy hoisting compartment. They have put in a good whim and all other appliances necessary to good mining. A drift started at 178 feet is now in over sixty feet, and drifting and sinking go along together. A shaft has also been sunk over ninety feet on the Excelsior and it is the intention to start one on the Big Wedge. The idea of the owners is to thoroughly prospect these three claims and the character of the work being done is an assurance that the development of this particular property will be of permanent value to the camp. The shaft being sunk on the J. I. C. is through country rock, no attempt being made to take out any ore until the 300 foot level has been reached, when they will start in and work up. This way of developing a mine is more expensive at the start and takes some capital to do it, but it is the cheapest way in the end, as all quartz miners know. They will also be able to work the Excelsior from the J. I. C. shaft. R. R. Ripley is the business manager for Mr. Brown in California and F. K. Klinefelter is the superintendent of the mines. Speaking with the latter about the prospects for the camp, he said he had every confidence in the district, that the surface indications were, the best he had ever seen and that capital could be used to good advantage” –Los Angeles Daily Times.
September 11, 1897: “THESE TWO CLAIMS (J.I.C. and Excelsior) along with the Big Wedge, form a group of mines lying just north of the Butte, Wedge, and Kinyon mines. They are the property of T. T. Brown of Denver, and Col. James A. Shinn of Leadville, both of whom are largely interested in mining in Colorado. On the J. I. C. they have sunk a double compartment shaft, four by eight feet, and are now down nearly two hundred and fifty feet. Instead of sinking on the vein they went through country rock and as soon as they reach the 300 foot level they will start in and work up, when they will be able to mine more ore a day and at considerably less expense than if they were digging out the ore as they went down. They have also put down a shaft on the Excelsior mine which, when they get down to the required depth, they will work from the J. I. C. shaft. The owners of these mines are to be congratulated on the methods they have adopted in developing them, for the results will show, unless all signs fail, that the mines of this district can, in the end, can be more economically and more satisfactorily worked then by going down on the vein.
In addition to the three mines mentioned above, Messrs. Brown and Shinn own a number of other claims in the district, among which are the Tom, White House, White Hills, Philadelphia, Serpent of the Desert and the Rattlesnake,” – Los Angeles Daily Times
October 31, 1897: “THE J. I. C, EXCELSIOR AND BIG WEDGE These are a group situated north of the Butte, Wedge and Kinyon mines. An incline double-compartment shaft has been sunk to a depth of 320 feet on the J. I. C, 175 feet to first level and 90 feet to second level; thence to the bottom, all varying in degree of incline. A shaft in the Excelsior will be connected with that of the J. I. C. There are cross-cuts at different points aggregating 300 feet. Eleven men are constantly employed and there are indications of a good ledge being close by. J. J. Brown, Denver, one of the owners of the famous “Little Johnnie” mine, Leadville, Colo., and Col. James A. Shinn, Leadville, are the owners. They are also owners of the Tom, White House, White Hills, Philadelphia, Serpent of the Desert and Rattlesnake.” – The Herald
June, 1904: “DEVELOPMENT ON THE EXCELSIOR, owned by Barton Filleld & Tonson is being pushed steadily. The showing from the tunnel which is now in something like one hundred and fifty feet, indicate a “good thing”. While the owners are well pleased with the prospect, they are not, as is the usual case, overly enthusiastic, but are showing their faith by their work and surely “getting there.” — Randsburg Miner
