Colorado Mineral Belt
The 250 mile long Colorado Mineral Belt cuts diagonally across central and southwestern Colorado, in the heart of the Rocky Mountains. Mt. Elbert (14,431 feet) is the highest of many high peaks in the belt, all of which were glaciated during the Ice Age. The region has heavy snowfall in the winter, with mild, pleasant summers.

Placers can be found downstream from many of the mining districts in the Colorado Mineral Belt. The best known placers are those on North Clear Creek west of Denver, at Breckenridge, at Alma and Fairplay, and at Leadville, all of which have been extensively worked. The richest gravels were at Breckenridge, where some 800,000 ounces of placer gold were recovered between 1859 and 1972. Placers in the Leadville area yielded over 350,000 ounces, and North Clear Creek yielded over 300,000 ounces of gold. The Alma-Fairplay placers also yielded around 300,000 ounces of gold. The richest and most productive placer gravels are in the Front Range (northeast) portion of the Colorado Mineral Belt. The bucketline dredge used at Fairplay was the largest in Colorado, and was in service until 1951.

Fairplay
The Fairplay district produced 202,000 ounces of placer gold, mostly along the South Platte River in the snowstorm and Fairplay Placers. Along Sacramento and Beaver Creek is excellent placer ground. The area Southeast of town in glacial out wash gravels contains placer gold. At the head of Fourmile Creek is the Horseshoe Mine and it was a good producer. North of Fourmile Creek and south of Mosquito Creek is the Sacramento Mine that produced a by product of gold.

Alma
The Alma district is located east of Leadville and had a total production of 1,320,00 ounces of lode gold and 28,000 ounces of placer gold between 1859-1959. Northeast of Alma about a 1/2 mile, along the east side of the South Platte River, the placers produced great. Coarse gold nuggets to several ounces have been found. All the area tributary creeks and gulches, in gravel deposits contain placer gold. On Mount Lincoln and Mount Bross, rich area lode mines, especially the London Mine (richest producer in the county, closed in 1942) produced most of the gold and silver. Near the head waters of the South Platte River, along the Continental Divide, on North Star Mountain, all area gulches contain placer gold. Northwest of Alma, 2~6 miles, many small mines produced lode gold. North of Alma 5~10 miles is the Consolidated Montgomery Mine. This mine is at an altitude of around 11,000 feet and produced a by product of gold. In Buckskin Gulch, the Sweethome Mine was a good producer. Around Mosquito creek, all streams produce placer gold.

BRECKENRIDGE
In the Breckenridge or Blue River district, including the tipper valley of the Blue River between the Front Range on the East and the Tenmile Range on the West had a total production of 1,000,000 gold ounces of which 735,000 ounces came from placer deposits. In all regional stream channels, gulches, benches, etc. you can find placers. East and northeast of town, in area of about 5 square miles, there are many lead-silver mines that produced a by-product gold. In Georgia Gulch, on North side of Farncomb Hill, rich area placers discovered in 1859, area lode mines, discovered in 1880, especially the Wellington Mine, chief producer, it was so rich in native gold that pockets supplied collectors and museums throughout the world with specimens of wire and leaf gold. Along the Swan and Blue rivers, many deep placers worked by dredges after 1900.

FRISCO
Frisco is located 4 miles southwest of Dillon and in the Tenmile district. It includes old camps of Kokomo and Robinson in the Tenmile Valley on the West Side of the Tenmile Range and had a total production from 1861-1959, of 52,000 gold ounces, mostly as by-product of base-metal ores. Area old mine dumps contains gold, with galena and pyrite. Various local small creek placers are around like Kokomo, in McNulty Gulch, rich placers discovered in 1861, and many mines along valley of Tenmile creek for 2-3 miles northeast and 5 miles southwest to Robinson. On East Side of valley, in the Tenmile Range, on West, slopes, many base-metal mines produced lode gold.
 

Strasburg

The best areas to prospect in Elbert County are: Platte River, Gold Run Creek and Ronk Gulch.

Platte River
All Platte River bars and terrace gravels contain placer gold.

Elizabeth

Grand Lake
East of Grand Lake 7 miles on route 278, the area lead silver mines had a by product of gold.

Kauffman Creek
Reported by: Tom Peden
Kaufman Creek is one of the five creeks that drains from the top of Gravel Mountain. Gravel Mountain, as its name implies is covered with gravel. Similar to that of Independence Mountain. All five of these creeks contain gold, but I've only prospected on Kaufman Creek. The heavy gravels in the bottom of the pan is just like those found on Independence Mountain. Leads one to think that these gravels are the result of glacial activity. On my last trip to the area, I found a false bed rock of conglomerate. With good gold at the contact zone. Have not found any nuggets, over 1/8", yet. But the area is worth prospecting.

Parshall
South of Parshall, to the head of Williams Fork, is the La Plata district. It extends a few miles southeast across Jones Pass on the Continental Divide in the headwaters of the West Fork of Clear Creek. The lode gold there is often associated with pyrite.

EVERGREEN
Half mile above town, on Cub Creek, small mines produced lode gold. South 1.5 miles on Route 73 is the Augusta Mine that produced a by-product gold. Southwest .75 miles on Northwest side of Cub Creek, along Route 334, and .25 miles Northwest of Route 74, mine with gold, with fluorite and silver. The Malachite Mine, notable copper producer by-product gold.

GOLDEN
West, along Clear Creek, to East, many good placers. Area sand and gravel pits are a source of most gold in recent years.
 
 

LAKE COUNTY, COLORADO
by: Tom Ashworth
Two of Colorado’s most important mining areas are in Lake County, Climax and Leadville. Only Leadville is important in gold production and accounts for most of its nearly 3,000,000 ounces. Since almost all of Leadville’s production was a by product of silver, weekend prospectors have overlooked both Climax and Leadville in favor of the Arkansas River placers.

Arkansas River
The entire Arkansas River Valley in southern Lake County has had productive placer locations with some of the better locations being Box and Lake Creeks and California Gulch. Most of the tributaries can be counted on to turn in small amounts of placer gold.

Reported By: Greg Ferris
The confluence of the Arkansas River and Lake Creek area was the general site of some the most extensive and successful placer mining operations in Colorado. Within a short distance are placer areas from numerous sources. Some 4 miles upstream from Lake Creek the Arkansas River is joined by Box Creek and several smaller outlets which provided source gold from the eastern slopes of Mount Elbert (Colorado's tallest mountain). This area was extensively worked for a considerable time period and is generally known as the Derry Ranch Placers. Lake Creek was a principal contributor of placer gold now found in the Arkansas River, draining water courses from the southern and southeastern slopes of Mount. Elbert and adjoining peaks. The majority of the gold originally was accumulated in moraine deposits, a short (6 mile) drive west on Hwy. 82 into the Twin Lakes area will quickly demonstrate the glacial valley. These lakes are now used for the production of hydroelectric power and the saving of fresh water. Originally the lakes (actually 1 lake) were created by two separate glacial flows with the end moraines providing the base dam and the upper/lower lake division. Needless to say with man's "damn" interference, gold no longer is sorted and fed down into Lake Creek from the glacial gravels. Just below the dam for a distance of about 3 miles Lake Creek again flows unimpeded. Dennis O'neil of Balltown, Colo. (a little collection of locals at the junction of Lake Creek and the Arkansas River) owns numerous claims on both Lake Creek and the Arkansas River which are open to daily fee users. Each of the various available claims areas is restricted to different prospecting methods. The most common activities are high-banking and panning. Dredging is allowed, by permit from BLM, on the Arkansas River. I have found that there are some virgin gravels on the Eastside of Lake Creek in the designated high-banking area but it is tough work as these are packed gravels. It should be noted that of the gold that is found, like most Colorado placer gold, it is of the "fine" variety and your prospecting technique requires care to maximize efforts. Occasionally small pickers and some minor flakes are found. Black sands are abundant and are filled with microscopic particles of gold. In this area water must be pumped almost 200' and considerably uphill. Fortunately you can drive to within 25-50' of the work area. Other areas are designated "panning only" along Lake Creek banks. On the Arkansas River, just 100-200 yards downstream from Lake Creek are some good high-banking areas. These most of these gravels are actually tailings piles from hydralicking and fluming operations of the late 1800's. The old miners must have only been interested in the big pieces because there are considerable fines and flakes to be found. Access is also easy by parking by State Hwy. 24 and crossing over railroad tracks to work area. Water access is also easier here although attention must be paid to fluctuating water levels as the hydroelectric operations on Twin Lakes can allow or stop large volumes of water in very short periods. I have discovered no real secret tips for working the tailings area, just make sure you aren't reworking the tailings of a "modern" prospector. The previously mentioned high-banker area on Lake Creek however does have distinct layers to be worked and better finds can be had for the gambler. As with most of the upper Arkansas River drainage no matter where you work you will find some success as I have never been able to run a single pan between the Pan Ark Lodge (Derry Ranch Placers) all the way down to Salida (50+ miles) without at least finding some color.

Box Creek
Along Box Creek, there was a large dredge operations for placer gold. Along lower Box Creek there was a most productive dredging operation.

Climax
Southeast of Climax 1 mile, in the Arkansas River Valley, 10 to 12 miles northeast of Leadville, is the Alicante Mine. It produced lode gold in pyrite ore. Four miles farther south, is the Birdseye Mine on the East side of the valley. It was a base metal mine, with a by product of gold.

Leadville
Leadville district had a total production of 2,970,000 ounces of gold. In the area there were many great mines. I read a few weeks ago that the last mine shut down in Leadville though (Feb. 1999 California Mining Journal). In Iowa and California gulches, there were some very rich placer mines. The old placer camp of Oro City, is now a ghost town. You couldn't tell that it once has over 10,000 residents. There are many placers that have to be worked using high bankers or trommels in the area.
