80 Acre Lode Claim — Republic District — Nye County, Nevada

Mining Claim Introduction

The Orizaba mining claim is a documented producing gold and silver mine located just north of the town of Tonopah in Nye County, Nevada. The mining claim is located in the Republic District, sometimes known as the Cloverdale District or the Orizaba District. The Mines are located on the eastern slope of the Royston Hills, an area that has a very short and spotty history. Gold and Silver are the primary commodities of the mines. Silver in abundant quantities.

The mine and camp have been referred to as the town of Republic but it is the assertion of Gold Rush Expeditions, Inc. that this is incorrect. The mine is the largest and most developed site in the general region for gold and silver extraction. There is a good, well documented history of the mine and the reported output, of which, much is likely unreported as to avoid taxation.

There are a number of workings that are contained on the claims and lumped into the Orizaba name. There are some workings west of the Orizaba shaft that have been known as the Cloverdale Ranch Mines. The mine was optioned and drilled in 1985-86 by INCO but there are no reports available of the findings.

The mine is located in a relatively dry region that will rarely see snow or heavy rains. The mine is in a remote area and any services required will need to come from Tonopah which is 39 miles to the south.

The Mine has consistantly reported values of 50 oz/T AG and .5 oz/T AU. Blocked reserves were reported at the 83’ level in sulphide ores.

Mining Claim Description

The Orizaba Mine was discovered in 1891 according to local oral reports. An outcropping of quartz and galena caught the eye of a prospector who filed claims on the property but did not develop it at all due to the low price of silver at the time. In or around 1901-2 a local prospector named Lou Miller purchased the property from the original locator.

Lou did minimal development work at the site but sent in several samples of ores which measured an average of 1 oz/T in gold and over 70 oz/T in silver. Lou Miller sold the property in an undeveloped state to John Conely probably around 1912. Mr. Conely proceeded to begin development of the property driving a shaft 100’ on the general strike of the outcrop and believed vein system. From 1913-1918 the mine produced a reported $127,980.00, this with silver at $0.70 per oz and gold at $20 per oz. With inflation accounted for to Feb. 2018, this is over $3.25 million dollars.

Work was done on a northwest-striking, southwest-dipping quartz vein in bleached limestone near an intrusive contact. The vein contains bunches of argentite, galena, and sphalerite in a gangue of quartz and calcite. Inclines at the Hyland property, east of the Orizaba, expose a N40°W, southwest-dipping shear zone in a bleached, altered volcanic rock near the contact with limestone of the Luning Formation.

Considerable drifting and stoping have been done on the upper level, and some high grade shipments are said to have been made. All of the work to date has been above the water level, but the present leasers are preparing to sink and develop the sulphide ore. A grab sample of the sulphide ores gave assay returns as follows: .45 oz/T Gold, 70.22 oz/T Silver.

The vein occurs along the contact of a light-colored limestone and granite .
In todays (2018) dollars, that same ore is worth $1700.00 per ton.

An excellent power line road leads from the main highway (not paved) to the mine and access is simple and direct. It is possible to drive a full size vehicle within ten (10) feet of any of the workings.

The Mine and camp are spread out over a wide expanse. A series of stone construction houses, workshops and other various buildings are strewn about the region. The most notable is an engine powered hoist at the main shaft. Boilers and remnants of the mining operation from 1913 to 1954 are visible.
The mine was last worked, according to records, in 1954, however, according to Norman Coombs, who began working the Orizaba in 1926 at age 12, the mine continued paying until the late 1970s when he was too old to go down the shaft any more. Coombs reported that the mine was rich in a strange “brassy” colored gold that formed like dice (cubes) but had no pyrite or iron. Mr. Coombs reported the sale of $1,000,000.00 in this “dice” gold to the US Mint in Denver in 1976.

The water level has not been confirmed, nor have the workings been mapped and recorded. The mine is noted as a gold mine in many publications, and a silver mine in others. Geological and Miners reports give conflicting information, but the validation of $1,000,000.00 in gold that was saved up and acquired from the Orizaba is an interesting idea.

In 1986, INCO was reportedly drilling the property for samples. These may be the core samples that were found lower in the mine buildings. There are no reports of the findings, and no INCO records to access. INCO was nearly bankrupt in the early 1990s and purchased by another company in early 2000

According to “Ghost Towns and Mining Camps of Nye County”

Ed Workman, who later discovered National, came across gold and silver ore in the western part of the Cloverdale District in 1909. He was soon shipping ore from the Orizaba mine to the town of Millers, in Esmeralda County. The property came under the control of the Diamondfield Black Butte Reorganized Mining Company based in Goldfield. The company was incorporated in 1905 and then reincorporated in 1910 with 2 million dollars in capital. The Diamondfield Company sold its claims to the Orizaba Mining and Development company but maintained a financial interest in the new company which was incorporated in 1915 with $1 million in capital.

In 1911 prospectors stake six claims covering 120 acres, the ore contained quantities of gold, silver, lead and copper. By October 1915 miners had uncovered over 1500 tons of rich ore in the Orizaba mine and processed another 1200 tons of lower grade ore in the tailings piles. During the next two years the Mines Selections Company gained control over all of the stock and assets of the Orizaba Company and became the property new owners. In 1917 the company moved mining equipment from the Golden to improve the Orizaba mine. Orizaba’s main disadvantage was the fact that 100,000 gallons of water were seeping into the mine every day.

By 1918 the holdings of the Mines Selection Company had expanded to 9 claims covering nearly 190 acres. It is interest to note that the Diamondfield Company owned most of the Mines Selection Company’s stock. The district production level continued to increase for a while, but by 1918 production had slowed due to water issues.

From 1913-1918 the mine produced ore valued at $122,000. In May of 1922, the Silver Mines Selection company, which was unrelated to the mines selection company, purchased all the holdings at Orizaba and began removing water from the mine. The Orizaba is documented to have produced over $128,000 in silver, which was only worth sixty cents an ounce at the peak of the mine activity.”
