MINING PROSPECTS IN COLORADO FOR 1882. 49 



From all sections of the State, reports received indicate that the coming season 

 will be the liveliest in mining operations ever recorded in the history of Colorado. 

 Not only are the Leadville and other mining districts flourishing, but, through- 

 out the State, innumerable small camps are springing up, many of which, it is 

 expected, will be heard from before the end of the year. Of course, active 

 mining operations, in many places, will be retarded for a time yet by snow ; but 

 preparations are making to resume work as soon as the weather will permit, on 

 claims that have long lain idle. 



CLEAR CREEK COUNTY. 



At Dumont, the Albro mine is shipping ore to the smelting- works at Golden. 

 The Unadilla Company is taking the average quantity of ore from the Eagle 

 mine, and is actively engaged in developing the mine by running levels and 

 cross-cuts, and in sinking the main shaft. A drift running on the vein from the 

 cross-cut in the Syndicate mine is in 124 feet, and exposes a vein about eighteen 

 inches thick of soHd ore upon the hanging-wall. 



At Montezuma, the Silver King concentrator is running steadily, working 

 about five tons per day. The Silver King mine is reported as looking excellent, 

 and is employing a force of twenty men. Connection was recently made be- 

 tween the first and second levels, by a winze. The Little Helen Mining Com- 

 pany is driving a cross-cut tunnel to the Hidden Treasure lode. The various 

 mines of less importance in the vicinity of Montezuma are reported as looking 

 very well. 



According to the census reports, this county produced during the year end- 

 ing May 31, 1880, $376,041 in gold and $1,954,547 in silver, assay value. 



GILPIN COUNTY. 



The mill of the California Mining Company at Black Hawk will start up in a 

 short time on ore from the California mine. The mine is yielding a fair amount 

 of mill-dirt and smelting ore. A good body of ore was recently encountered in 

 driving the 150-foot level of the Mountain City, west from the working-shaft. 

 Twenty-five stamps of the New York mill are dropping on ore from the United 

 Gregory lode. The other fifty stamps are working ore from the Cotton and other 

 lodes. The Quartz Hill Company is meeting with fair success in the develop- 

 ment of its mine, and expects in a short time to have the mill running. 



The more prominent mines in the vicinity of Central City continue as at last 

 report, and the mills are kept busy crushing the product. The California Con- 

 solidated Mining Company, which recently purchased the Standley-California 

 mine, has begun work on the mine, and expects to have the fifty-stamp mill in 

 operation in a few weeks. 



Production for the census year $2,012,134 in gold, $674,727 in silver. 



THE SAN JUAN REGION. 



The San Juan region has always been understood to comprise Ouray, Do- 

 lores, Hinsdale, La Plata, San Juan and Rio Grande, and in it are the well-
