Below the letterhead is "Mines located at Rock Cut, Washington" and the agent was located in Ritzville, WA. Incorporated in Washington. The letters do not offer the type of ore being mined, but does mention that a tunnel was being driven and ore ran at $14 to $70 a ton. This would suggest a gold deposit or a very rich copper rich. The envelope is addressed to a man who lived in Ritzville. The town of Ritzville today is hardly a gas stop located in the southern portion of the Palouse (dry wheat farming region) in eastern Washington. Not listed in the Mines Handbooks. Very fine. $35

949. Washington. Colville Reservation. Moses. Multnomah Mining, Milling & Development Co, 1902. Prospectus and market letters. Incorporated in Washington. Promoted from Michigan, but this office moved around the country through time (Copper & Mines Handbooks). The company owned 8 claims on the Colville Indian Reservation in east central Washington, near the town of Nespelem in the Moses district. Ore carried copper and gold values running between $6 and $40 per ton. The 1910 Copper Handbook, lists that the company had expanded its holdings to 600 acres including very favorable placer deposits and was employing 6 men. A dam was built in 1907 on the Nespelem River for power and 5 buildings had been erected. A tunnel had been driven from less than 10 feet in 1902 (prospectus) to over 1000 feet by 1910 with high grade copper and bold ore being encountered (p.1243). The company was idle by 1916. This is one of the few companies that we have seen that ran a somewhat successful business on an Indian Reservation. Typically, non Native American mining companies were forced off the reservation property. Includes several letterhead correspondences dated 1902 mostly sent to stockholders. Prospectus has one photograph on the first page. 16 pages, original gray cover with dark gray print, 4.5 x 9". Prospectus Xf, Letters Vf. $50

The reverse side of this is a sales pitch for investors to buy stock at 5 cents before the price goes up to 10 cents in just a few weeks. 8.5 x 12", with tears along the fold creases. The second item is a postcard sized mailer soliciting potential investors to purchase stock of the Great Standard Copper MC before the price jumps to 10 cents a share on August 18, 1903.

The first item is a prospectus entitled "Ground Floor Ideas, Montezuma Mining Co, 1900" that covers justifications for investing in mining companies early on prior to full mine development. Original brown cover, 3.5 x 9", 4 pages. The second item is a true company prospectus. Property was located in 2 different districts, Carbon River and Tahoma. Real property owned outright was the Dakota, Ellis, Ellis Ext, Emma, Chicago and Nevada. But these properties were not development and were not the main focus of the company's plan. Rather, the leased Blue Star claim group was being actively tunneled claiming to be in a 4 foot wide pure chalcopyrite assaying at 32% copper. In the prospectus, the Blue Star property was leased from the Blue Star MC, which in the Copper Handbook, was listed as having property in Stevens County with no mention to the Blue Star group.

Also wanted to build smaller, 50-100 ton smelters, in each of the following mining districts in Pierce County: Carbon River, Summit, Glacier Basin, Mowich, Mashel and Mineral Creek. An advertisement cut out from a publication is attached at the upper left corner. Company not listed in the Copper Handbook suggesting that it never got off the ground. Discolored from contact with acid paper. Very fine. $50

967. Washington. Pierce. Summit. Medina Gold Mining Co, 1905. Lot of 2 different prospectuses and a market letter. Incorporated in Washington. The company owned property in Washington, California and Ontario. The Washington property was located on the west side of Crystal Mountain (now one of the West Coast's best ski resorts) in the Summit district. According the 1905 prospectus, the tunnel had driven nearly 600 feet, assaying at $30-$40 gold, silver and copper per ton. The California property was at Oro Fino, Siskiyou County. This property was under lease at a $1 royalty per ton ore retaining any profit on ore that ran $7. Ore that was more than $7, was to be split evenly to the leasers (doesn't sound like a great contract to me - vp). Finally, the property in Ontario was located in Hastings County was known as the El Dorado mine. Initially, this mine was developed for the rich hematite found at the surface. Below the iron zone, was copper mineralization being considered the only viable copper play in western Canada. There are 2 prospectuses in this lot. One is from 1901, 6 x 8.5" and has a newspaper advertisement attached on the last page, total of 12 pages. The second prospectus is from 1905, measures 8.5 x 11" with 4 pages. This prospectus has been through a little more rough handling with the front and rear pages detached, chips and small tears along edges and dirt stains along fold creases. The Copper Handbook, 1908, p.928, shows that the Medina Gold MC was succeeded by the Medina Copper MC in 1907 being operated by the same management and Syracuse, New York promoter. Medina Copper MC was only operating the El Dorado copper property in Ontario, Canada. Under the listing for this company (same page in Copper Handbook), is "practically as successor of the Medina gold Mining Co, which went out of business suddenly, after paying several dividends, presumably, unearned. Apparently has disposed somehow of its lands at El Dorado, to the Ontario Copper Co, which is practically under the same management. Is not regarded favorably." In the Copper Handbook, 1910, p.1346, lists the Ontario Copper Co as "Dead. Was a bad egg." $100

971. Washington. Snohomish. Index. Ethel Copper Mining Co, 1900. Lot of 5 different pcs. The Ethel mine was located about 5 miles from Index and, as typically found in prospectuses, was touted as the next great copper mine of the west. The mine was purchased in 1899 from the discoverers, Sam Fourtner and L. C. Engle, for $40,000. The Ethel Copper MC immediately put 27 men to work resulting in a 600 foot drift of which 270 feet were in ore assaying at $15 to $140 per ton copper. This information was gleaned from the first prospectus which is 12 pages, original green cover with gilt lettering and 3 x 6". A second prospectus offers similar information with more verbiage and detail as compared to the first just described. In the section about the metalliferous deposits it states that the ore in the region occurs with gold, silver, copper and lead and in most cases, "in rebellious combinations." (I wonder if the minerals were in their teenage years - vp). This prospectus is in a legal format layout with the last 4 pages, of 6 total, having copies of assay reports. Original green cover, 8 x 13". A third item included is a "Letter to the Stockholders, Nov. 1901."

A 4th item is a letter to stockholders announcing the initial run of the newly constructed concentrator on April 21, 1902. This letter goes on to solicit existing stockholders to help buyout the remaining 25,000 shares in the treasury to help finalize construction debt. In September, 1902, a letter was mailed to the stockholders of both the Ethel Copper MC and the John D. Copper MC (company with property immediately adjoining the Ethel) informing them that the two companies were to be merged with a stock exchange in the new company incorporated as Ethel Consolidated Mines (please see the lot above). The correspondence letters are 8.5 x 11" and have minor tears along fold creases. All are fine to very fine. $100

As reported in the Annual Report, 1902 (the 2nd item in this lot), a 350 foot tunnel had been pushed on the Lone Star claim with ore values returning at about 5% copper with minor silver and gold. The company was named after the town of the same name in Pennsylvania, where most of the directors were located. The Copper Handbook, 1905, p. 499., lists that the company is probably dead. The prospectus was printed by Mensing-Muchmore Press, Seattle, has 4 fold creases that unfolds to form 10 individual, attached, pages, 3.5 x 5.5".

The company owned the Captain Smith and American Girl claims in the Stillagaumish district near Granite Falls, Snohomish County. The prospectus claims that the Tillicum MC had done work previously on this same property reporting ore values at $6 to $71 a ton. According to the company, no work had yet begun and was also looking to purchase other properties. A lackluster sales pitch and the company probably never really got off the ground. Not listed in the Copper Handbooks. The last page has a map of the region showing the location of Everett (where the major smelter was located) relative to Granite Falls, where the property was located. 4 pages, original red cover with black print, 4.5 x 6".

Promoted from New York. $50

976. Washington. Stevens. Chewelah (New Era). Alice Gold Mining Co, c.1897-1900. The prospectus claims to own the Stella Mine in the New Era district, without offering the county or state. Headquarters were in Spokane. Interesting that the company has Gold in the title and the review of the property discusses the nature of the copper ore. The company is listed in the Copper Handbook, 1906, p.173, stating property as being 11 claims in the Chewelah district of Stevens County showing good values of gold and copper. Supposedly there were two 200 feet shafts and 2 short tunnels. Considered idle. The company was incorporated in 1896. 8 pages, 3.5 x 6". Extremely fine. $50

The company had extended a pre-existing tunnel to 215 feet at the bottom of a 158 foot shaft. Ore ran between 3 & 33% copper with varying amounts of silver. On the last page is a map that shows the company's property in relation to other companies and distances to Newport and other rail stops. As reported in the prospectus, the ore cost $14 to get one ton to the smelter. This would require an ore reserve of very rich assays. 10 pages, original gray cover with dark blue print. Cover is tri-folded, 3 x 5" that unfolds to 6 x 6". Printed by Mar-Har Printing Co, Chicago. Not listed in the Copper Handbooks. Minor dirt stains on front cover. Very fine. $75

This step was taken after an agreement was reached between the Wauconda and the Rossman Reduction Works to build a mill at the mine location in exchange for shares in the Wauconda. The company had a 215 foot tunnel that had to be completed to 500 feet in order to have a sufficient amount of ore to feed a mill. Neither of these companies are listed in the Copper Handbook. 4 x 7.5". Discoloration along left edge. Very fine. $50
