Mining scrip

Mining enterprises, by their very nature, were often located in isolated mountainous areas with low population densities significantly distant from commercial centres. Mining entrepreneurs, therefore, had unique problems to contend with in organizing their enterprises. Their common problem was a lack of infrastructure—no streets, no churches, no schools, no residences, no utilities, and no banks or financial intermediaries. The specialised industries that might otherwise have provided these services were dissuaded from doing so by the high start-up costs and the enduring uncertainties of dealing with low-income communities that might be there today and gone tomorrow. Mining companies, therefore, built residences, churches, schools, and water works, and opened company stores or commissaries. In so doing, they became both buyers of labour from, and sellers of commodities to, the miners and their households. This kind of organization invited the use of scrip in lieu of ordinary money.

Scrip in the very beginning was little more than credit advanced against wages. Given the fact that most employees were earning merely enough to survive (or less) there would be little left at payday except the reckoning of accounts. If the company operated its own store (tienda de raya) the worker would draw goods against a personal account: this need not have involved anything more than book-keeping but sometimes more elaborate arrangements were used.

For instance, scrip coupon books ‘eliminated the tedious bookkeeping chores that were incident to over-the-counter credit (day book or journal entries followed by ledger entries)’. When a coupon book was issued to an employee ‘he signs for it on the form provided on the first leaf of the book, which the storekeeper tears out and retains for the company time-keeper, who deducts the amount from the man’s next time-check.’ Then, when the employee buys goods from the company store, ‘he pays in coupons, just as he would pay in cash, and the coupons are kept and counted the same as cash . . . . The coupon book is a medium of exchange between the company employees and the company store’Richard H. Timberlake, Free Market Money in Coal-Mining Communities, in Journal of Money, Credit, and Banking, vol. 19, no. 4 (November 1987).

Such scrip could also be used, usually at a discount, at other local establishments (run in the main by Chinese immigrantsWithin Sonora, a clear division developed between Mexican and European merchants on the one hand and Chinese retailers on the other. Established Sonoran retailers and agents, representing Mexican companies, (such as Seldner and Company, García and Bringas, and Anibal Mancini of Guaymas) opened stores and franchises at the mines. These major establishments catered to foreigners and Mexicans with economic resources, selling both luxury goods as well as basic necessities such as underwear, shirts, trousers, boots, sugar, and coffee. Unlike their Mexican counterparts, Chinese merchants usually sold inexpensive items, such as low-cost apparel, which miners could afford. More importantly, many Chinese also sold goods on credit, a practice frowned on by Europeans and other larger Mexican merchants. Stores such as those operated by Sam Lee at Minas Prietas and Fong Hong at La Colorada maintained copious credit records for their clients. On the wall of the store, small boxes with the names of the clients recorded a person’s debts. In this capacity the Chinese prospered and quickly established a monopoly over the lower spectrum of the consumer market.), provided these in turn had some arrangement for cashing in the scrip. As the company store did not sell alcohol – for the obvious reason that its sale would encourage absenteeism and worker inefficiency – workers also had to find ways to sell scrip for conventional currency in order to buy drink.

Besides overcoming the difficulty and danger of importing specie, another advantage of scrip was that the company could pay almost its entire payroll in scrip, disturbing only a few pesos of actual working capital, though it needed working capital for store goods.

In 1898 the Guaymas newspaper El Correo de Sonora reported that the district judge has instituted an investigation into the practice of several local mining companies paying their workers in 'boletas' payable only at the company storesThe Two Republics, Mexico, 3 June 1898. A good descripton of boletas comes from Charles D. Poston's account of the Santa Rita Mining Company, in Tubac, Arizona, 80 kilometres north of Nogales, which, but for Manifest Destiny, would have been in Mexico. Believing debt peonage to be the norm, this company paid Mexicans twelve to fifteen dollars monthly versus thirty to seventy dollars a month plus board for Anglos, and it even lowered these costs by paying Mexicans with marked-up items from the company store. It paid Mexican workers with boletas, or coupons, which Poston claimed were used “among the merchants in the country and in Mexico.” Thirty-two percent of these Mexican “wages”, noted a colleague, returned to the company as profits at the company store. "Silver bars form rather an inconvenient currency, and necessity required some more convenient medium. We therefore adopted the Mexican system of "boletas". Engravings were made in New York, and paper money printed on pasteboard about two inches by three in small denominations, twelve and one half cents, twenty-five cents, fifty cents, one dollar, five dollars, ten dollars. Each boleta had a picture, by which the illiterate could ascertain its denomination, viz: twelve and a half cents, a pig; twenty-five cents, a calf; fifty cents, a rooster; one dollar, a horse; five dollars, a bull; ten dollars, a lion. With these "boletas" the hands were paid off every Saturday, and they were currency at the stores, and among the merchants of the country and in Mexico. When a run of silver was made, anyone holding tickets could have them redeemed in silver bars, or in exchange on San Francisco. This primitive system of greenbacks worked very well,—everybody holding boletas was interested in the success of the mines; and the whole community was dependent on the prosperity of the company. They were all redeemed" (Charles D. Poston, Building a State In Apache Land, 1894, pp 81-82).

Another system of boletas was described by James Wyatt Oates, in his "A Trip Into Sonora", published in The Californian magazine in 1880The Californian, vol. II, August 1880 .

 Foreign mining investors

At the end of the nineteenth century there was a surge of foreign investment in mining in northern Sonora, with some foreign corporations establishing company towns. The largest were those of the Cananea Consolidated Copper Company, the Moctezuma Copper Company, El Tigre Mining Company and the Creston Mining Company. The owners controlled everything in these towns: food, housing, schools (where available), the police, and local government.

The tiendas mixtas of the mining companies had a far greater turnover than the average shopkeepers in the area and competition from local independent merchants was discouraged because it endangered the profits of company stores. The tienda of the Cananea Consolidated Copper Company in Cananea had annual sales of 145,000 pesos, compared with 12,000 and 20,000 respectively of its nearest competitor, the grocery store of Hofman y Claud. The tiendas of the Moctezuma Copper Company in Placeritos and Pilares, both in Nacozari, had combined sales of 30,000 pesos per year compared with the 8,000 pesos of Juan Manuel, their nearest competitor in the municipio: whilst the tienda of The Lucky Tiger Mining Company in the mining town of El Tigre sold 25,000 pesos compared to the 2,100 pesos of its nearest rival, Francisco H. Langston.

Santa Rosalia Mining Company, Arizpe

The rich gold mine of Santa Rosalía, fifteen miles west of Arizpe was worked by the early Spaniards but abandoned when the water levels were reached. In 1880 George F. Beveridge, the Superintendent of the El Gascher mine in Sonora, located the abandoned mine, but for ten or twelve years he could do nothing with it and held it merely by relocation. Finally in December 1894, Beveridge gave a deed of the property to a company organized by a group of San Francisco businessmen, with Beveridge to take his pay for the mine in stockSacramento Daily Union, Volume 95, Number 26, 19 March 1898. Beveridge and Augustus A. Abbott took personal charge with Antonio Acuña, of Arizpe, as foreman. At first results were not very satisfactory but one day Acuña found at one place, against the side of an arroyo. a lot of rubbish which he cleared away, uncovering the entrance to an old tunnel, closed with a heavy wooden door and locked. The door was soon opened and the tunnel traversed a distance of 300 feet, when another door was encountered. Passing that they entered the old Spanish workings. There they found a two foot streak of ore so rich that the first carload shipped netted $22,000 in gold, and the first three carloads averaged more than $20,000 eachThe Oasis, Nogales, 3 August 1901.

In September 1897 he accepted a similar position with the Santa Rosalia Mining CompanyThe Oasis, Nogales, 4 September 1897 but resigned after a couple of months, supposedly in order to look after the interests of his own properties near the La Mexicana mine. He was replaced by a W. J. Coleman, an experienced mining man from CaliforniaThe Border Vidette, Nogales, 11 December 1897. However, it seems that Lindsay was always merely a stop-gap, standing in between Augustus Abbott and Coleman. And by July 1898 E. J, Murray of San Francisco, at one time manager of the Trinidad mine, of Sonora, was the new superintendent (The Oasis, 16 July 1898). sig Lindsay


Moctezuma Copper Company

The mines at Pilares de Nacozari, six miles from Nacozari, were established around 1867 by U. B. Treaner as the Moctezuma Concentrating Company. The mines passed to the Guggenheims, and in 1896, as the Moctezuma Copper Company, were acquired by the American Phelps, Dodge and Co.

Because of their Quaker convictions Phelps, Dodge built a model town at Pilares: instead of adobe huts, the miners lived in one-room cottages fifteen-foot square and the company supplied clubrooms, libraries, billiard parlours, dance halls and shower baths. In Nacozari, the company had a smelting plant and a generating plant, operated the railway to Agua Prieta and Douglas and provided stores, a public library, hospital and school. By 1910 the company controlled a town of 4,000 inhabitants: it paid the salaries of the comisario, the schoolmasters and the police.

The Moctezuma Copper Company paid with boletas to be used only in the company store. One such boleta was of yellow cardboard. On the face it read

At the end of the month the company paid any outstanding salary with a cheque drawn on a distant bank. It was willing to encash these cheques on condition that 10% of the value was spent on merchandise in the company store, but the worker then just received another cheque for a smaller amountRegeneración, 11 March 1905.

There was a Banco de Moctezuma in Moctezuma, 80 kilometres south of Nacozari, with the Compañía Mercantil, bank and hotel all housed in the same brick building on the main squareMr. Hunter was the manager (Manuel Guerrero, Album Descriptivo del Distrito de Moctezuma, Cumpas 1909).

In Cumpas, midway between Nacozari and Moctezuma, El Tigre Mining Company gained its concession in exchange for maintaining a school and paying for the police.

El Tajo Mining Company

El Tajo Mining company operated the San Gerónimo mine, located 18 miles east of Poza, a station on the Sonora railroad, in the district of Ures. In July 1912 the Comisario de Policía at San Gerónimo reported to the state government that company was breaking the law by issuing vales or ‘tikets’ in its tienda de rayaEl Estado de Sonora, 6 August 1912. However a report of 31 July stated that the company was paying with cheques, which people had difficulty changing, because of a lack of coinageAGHES, Fondo Oficialidad Mayor, tomo 2913.

La Trinidad

The La Trinidad mines at Sahuaripa, 165 kilometres east of Hermosillo, had been owned and operated by the Matias Alzua family for many years, but in 1884 were sold to James Thomas Browne of England. Browne sold the property on to La Trinidad Limited of London for a handsome profitAGHES, tomo [ ], caja 547: La Constitución, 5 October 1883. La Trinidad Limited, incorporated in 1884, issued 100,000 shares of stock at five pounds each.

The new owners of the La Trinidad mines immediately encountered several problems which hampered their operations and also suffered from poor working relations with the miners and the local townspeople, especially the merchants. Discontent erupted into a strike in February 1888. The labourers demanded more pay, claiming that one peso a day for work outside of the mines and one and a half pesos for work inside was too low. On the grounds that the miners were receiving the highest pay in any mining area, the company authorities refused to meet the demands, and attempted to break the strike by bringing in Yaqui miners plus other workers from outside the district. Although the strikers refrained from any violent actions, they cursed the strikebreakers who arrived on 15 February and hindered the operations of the companyAGHES, tomo 185, caja 606 letter District Prefect Loreto Trujillo to Governor Ramon Corral, 17 February 1888. Because the mine could operate at only partial capacity, the General Manager, Edmund Harvey, requested help from the presidente municipal, Antonio Encinas distinguish between Antonio Encinas and senior alderman (Primer Regidor) Manuel Pablos Encinas, who encouraged the workers. Encinas relayed the message to the prefect of the district, Loreto Trujillo, who rode all night from Sahuaripa to arrive at La Trinidad on 16 February. Trujillo immediately posted a guard of twentyfive men to protect the mining properties and personally informed the general manager that his operations would not be harmed. After conferring with Harvey and Encinas, Trujillo arrested three of the leaders of the strikeAGHES, tomo 185, caja 606 letter Trujillo to Corral, 17 February 1888: letter Trujillo to Corral, 25 February 1888, and the following month they were sentenced to two months imprisonment for crimes against industry and commerceRamón Corral, Memoria de la Administración Pública del Estado, Hermosillo, 1891.

Before returning to Sahuaripa, Trujillo left orders for Encinas to notify him if any further disturbance occurred. Moreover, he had Encinas post a decree stating that any citizen who lacked an income should present himself for work under penalty of vagrancy. Included in the decree also was a declaration that any person or persons who attempted to employ the use of violence, physical or moral, for the purpose of increasing or lowering the wages of workers, or to impede the free exercise of industry, would be immediately apprehendedAGHES, tomo 185, caja 606 Manifesto 19 February 1888. Trujillo returned to Sahuaripa where he drafted a detailed report of the incident for the secretary of state. Governor Corral ordered Trujillo to continue to protect the mining operations and the official state newspaper, La Constitución, printed one short statement condemning the strike, and agreed with Edmund Harvey that La Trinidad Ltd. paid the highest wages in any mining districtLa Constitución, 24 February 1888.

However, discontent continued and threatened to erupt into a violent clash between the workers and company officials. In addition to the complaint of low wages, the miners claimed that the company's established policy of payment in script, which could then be redeemed at local stores for goods, cheated them of their earnings. The company did not intentionally cheat the miners, but, unfortunately for the labourers, the English firm did not enjoy good relations with the local merchants, and only about half of them would accept the script. Those merchants who did accept the company's script discounted it as much as one-third of its value. Instead of seeking redress from the merchants, the miners blamed the company and demanded that they be paid silver each weekAGHES, tomo 185, caja 606 letter Trujillo to Corral, 22 February 1889. After the strike Harvey promised that he would reform the method of pay for the miners, but he delayed doing so for several months while tension mounted steadily among the workers. Finally, in a desperate attempt to alleviate the pressure which hampered the operations of the company, Harvey agreed to pay the workers each week, and he also established a company store where the labourers could purchase goods at cost price. Harvey's actions satisfied only one of the grievances and the majority of workers still demanded an increase in pay and now the local merchants became even more hostile because they resented the competition from the company store. The discontent affected the operations of the mines and production decreased considerablyAGHES, tomo 185, caja 606 letter Trujillo to Corral, 22 February 1889.

Instead of requesting help from either the district or the state level or even from the British ambassador in Mexico City, Harvey bombarded the London office with complaints. Steward Pixley, the Chairman of Board of La Trinidad Limited, requested help from the English Minister of Foreign Affairs, Lord Salisbury. Salisbury's office contacted the English Ambassador to Mexico, Sir Spenser St. John, who informed the Mexican Minister of Foreign Affairs, Ignacio Mariscal, who in turn called upon the Secretary of Fomento, Manuel Fernandez, who notified President Díaz about the problem confronting La Trinidad Limited. Díaz ordered that he wanted the labour disturbances to endAGHES, tomo 185, caja 606, Manuel Fernández, Secretario de Fomento, to Corral, 12 January 1889. At the same time that Corral replied that he was aware of only one strike against the company and that one had been settled to the satisfaction of the company, he also ordered Trujillo to check into the matter AGHES, tomo 185, caja 606. Trujillo, in turn, sent an inquiry to the local president municipal. About the time that Encinas replied with his report on conditions at La Trinidad, Harvey made his first report of the situation to the district prefect. Encinas informed Trujillo about the changes which the company had made in October and November concerning the pay of the workers and the company store which had been established for the miners and assured the prefect that the local authorities had and would protect the mining operation. According to Encinas, "the workers are much happier and only a small percent remain discontented but these are among the most ignorant and insignificant element ( )AGHES, tomo 185, caja 606 Encinas to Trujillo, 13 February 1889”. Contrary to the picture of tranquility which Encinas described, Harvey complained of a lack of guarantees by the presidente municipal and alleged that his company was the target of discontent within the community. Moreover, he complained that some of the leaders of the 1888 strike had returned to the area and were agitating those who work in the minesAGHES, tomo 185, caja 606 Trujillo to Corral, 22 February 1889.

On the basis of Encinas’ letter, Trujillo dismissed the complaints by Harvey and in his report to Corral, the district prefect wrote that Harvey and his attorney "yell strike at what has occurred since time immemorial in this mining area: that is, workers arrive for a week or more of work and when they have earned enough for their needs they return home for a number of days. Mr. Harvey calls this a strikeAGHES, tomo 185, caja 606 Trujillo to Corral, 22 February 1889”. Trujillo accompanied his letter with that of Encinas which reported that no major difficulty existed at La Trinidad. Corral seemed satisfied with the general report. He agreed with the district prefect that Harvey's complaints were too vague and too general to stand up in court. "It is important," Corral wrote, "that Mr. Harvey knows that if Manuel Pablos Encinas or another person is promoting disturbances that concrete evidence must be obtained in order to prosecute. These acts must be proved before the lawAGHES, tomo 185, caja 606 Corral to Trujillo, 1 March 1889

On 24 February 1889, just two days after Trujillo notified Corral that all was well at La Trinidad, a group of miners attacked several of the officials of the mining company. According to the company superintendent, Richard R. Hawkins, about eight o'clock at night while the mine superintendent, Mr. J. Fredenrick, sat on the front porch of his home talking with four or five other employees, a gang of half drunken natives appeared and began to insult the men in the grossest manner, calling them "gringos cabrones." When Fredenrick requested that they leave, the miners bombarded the house with rocks and drove the group inside. The superintendent and his friends barricaded the doors and "patiently awaiting succor stood the little band of pale determined men firmly grasping their revolvers determined to sell their lives dearly— They could have shot down scores and their self restraint is simply marvelous when you consider the ordeal through which they were passingAGHES, tomo 185, caja 606, Hawkins to Consul Alexander Willard, 25 February 1889. The noise attracted Hawkins and, with the cooperation of the local authorities, he organized a force to suppress the outbreak.

After this violent outburst, Harvey contacted Corral requesting that he induct the trouble makers into the militaryAGHES, tomo 185, caja 606 Harvey to Corral,26 February 1889. Corral replied that he could not grant this request but did apologize for the attack, stating that "it causes me much pain to see your business attacked and you can be assured that I shall see with the greatest interest that peace and guarantees are enjoyed by your company. I ordered Prefect Trujillo to see to it that those who attacked Fredenrick and his friends are punished with all the vigor of our lawsAGHES, tomo 185, caja 606 Corral to Trujillo,7 March 1889". At the same time Corral sent a stinging rebuke to Trujillo instructing him to protect the mining company as he previously had been ordered. "I now repeat those orders to you and that those guilty be punished with all the vigor of the law”. Corral added that the prefect was to make sure the local judge understood the situation, and received the proper instructions concerning the sentence AGHES, tomo 185, caja 606 Corral to Trujillo,7 March 1889.

Harvey wrote again to Corral explaining that the miners who continued to work for him could not enter town without being harassed by rock throwers, and that Encinas had done nothing to prevent the attacks. He further complained about the erratic work habits of the miners which caused the company. to run at half capacityAGHES, tomo 185, caja 606 Harvey to Corral, 16 March 1889. Even if Corral had demonstrated his willingness to protect the mine’s property, he realized the futility in trying to alter work habits which had developed over many decades. So he replied that he knew of no law which obligated a man to work for a determined number of days a week. In regard to Encinas, Corral suggested that the general manager use his influence in the municipal elections scheduled in AugustAGHES, tomo 185, caja 606 Corral to Harvey,26 March 1889.

The company's total lack of knowledge of local customs became even more apparent when Harvey returned to England in late April 1889 One of Harvey's letters to the home office in London clearly demonstrated his inability to make judgments. According to the Englishman, "the present Governor has no love for foreigners (Gringos as we are called.). If a Mexican wants anything even if it is out of the common, he gets it at once but we get nothing . . . (FO, F. 0. 50, vol. 472, Edmund Harvey to Stewart Pixley,1 October 1888, quoted in Stewart Pixley to Sir T. V. Lister,26 February 1889). However, in reality Corral worked to attract foreign companies to Sonora and always cautioned the local authorities "to give all kinds of guarantees to the mining companies." (AGHES, tomo [ ], caja 651 Corral to the mayor of Minas Prietas, 12 December 1892: tomo 185, caja 606, Corral to Trujillo, 7 March 1889). The company’s attitude is also demonstrated by the superintendent, Richard R, Hawkins, who could write “The La Trinidad Limitada have always treated their native employees in an exceptionally kind and liberal manner. Not only do we pay higher wages than elsewhere in Mexico but we have opened a general store where all of our workmen can purchase supplies of every description at the cost price to us, an excess of liberality unparalleled in Mexican mining history. Our treatment of the men has been really patriarchal, and this outbreak is consequently inexcusable (AGHES, tomo 185, caja 606, letter to US consul, Guaymas 25 February 1889 my italics). The general manager reported that the problems which confronted the mining company in Sonora stemmed from the local authorities not carrying out the orders of the district prefect. Pixley, the chairman of the board, forwarded Harvey's comment to Lord Salisbury and requested that the minister of foreign affairs use his influence with the Mexican government to obtain a favorable appointment to the position of president municipal at La TrinidadFO, F. 0. 50, vol. 472 Stewart Pixley to Foreign Office, 29 April 1889. Ambassador St. John, who answered Pixley, informed the chairman that municipal positions were arranged at the state level and not the national level and the ambassador suggested that the company give pecuniary assistance to the local authorities to prevent further difficulties. "Mexican officials are so poorly paid, that they will always aid a foreign company that has no objection to making their position more endurableFO, F.0. 50, vol. 468 Spencer St. John to Sir T. H. Sanderson, 4 May 1889".

In spite of Corral's efforts to alleviate the problems of La Trinidad Limited, the mining operations folded in 1893 and the property reverted to the Alsua familySD papers, J. Alexander Forbes to secretary of state. May I, 1893, "Consular Despatches, Guaymas," roll 9.

La Quintera

On circumstantial evidence La Quintera Mining Company Limited is one of the best candidates for issuing paper. This mine was situated at La Aduana, just west of Alamos. It was discovered in colonial days and operated under various owners until 1909 when work on a large scale was suspended.

In 1898 Brigido Caro, editor of El Sonorense, a newspaper published in Alamos, revealed that the mining company was monopolising the public water supply at La Aduana, denuding the hills of wood and timber and illegally paying its workers with scrip (cacharpas). Caro’s articles aroused people to demand that the abuses be corrected and with the aid of the state governor the mining company was forced to reform and pay a large indemnity to the cityRachel French, Alamos Sonora’s Silver City, in The Smoke Signal, Spring 1962, Tucson.

It is known that the company issued metal tokens, manufactured by L. H. Moise of San Francisco, and appears to have also reused old stocks of tokens from Ocharan y Cia. of Palmarejo, ChihuahuaElwin C. Leslie, The Palmarejo Railroad Token, in Plus Ultra, 69, [ ] but it may also have used paper. Both the mining company in nearby Palmarejo, which did issue paper, and this Alamos company were British owned and both shared, as agent in Guaymas, Luis A. Martínez.

In his youth Ignacio Lorenzo Almada ran the accounts for La Quintera. Ignacio Lorenzo established a casa comercial in Alamos in 1893 and was the Alamos agent of the Banco Minero de ChihuahuaJ. R. Southworth, El Estado de Sonora. Sus Industrias, Comerciales, Mineras y Manufactureras, Nogales, Arizona, 1897, whilst another member of the family, Jesus G. Almada, signed the notes used in the tienda de raya in Palmarejo.

Minas Prietas

Minas Prietas (now La Colorada) is situated 45 kilometres south east of Hermosillo. At the Creston mining companyIn the 1860s, Ricardo Johnson, with the financial backing of the wealthy Ortiz merchants of Hermosillo, acquired the rights to the Minas Prietas mines. For several years Johnson worked the site, but his presence did not lead to any formal settlement in the area. Like many Sonoran elites of the time, Johnson and his benefactors did not have any long-term interest in actually exploiting the mine but rather hoped to profit by selling it to foreign investors. In 1886 he sold his claims to several Americans (The Oasis, 28 December 1895). Other Sonoran notables, including Ramón Corral, Ignacio Bonillas, Pedro Negro, and Pedro Pinelli, also joined the early rush to claim mines at Minas Prietas ("History of Amarillas" The Oasis, 30 December 1899). Corral did not mind using public office to enrich himself and his close associates. In 1896 this group sold their interest to the Gran Central and made a handsome profit. The company retained the services of the governor as their consul and paid him $250 a month until 1906 (Biblioteca CRN-INAH, Libro de contabilidad “Crestón Colorado Co.”, Sep-Nov 1905).

Eventually two large concerns, the London Exploration Company, owner of the Grand Central Mining Company, and the Ohio-based Crestón Colorada Mining Company bought out a host of smaller operators and acquired a mining complex which extended over several miles between Minas Prietas and La Colorada. In the early 1900s, the Ohio group sold their interest in the mine for close to $5 million to a New York company headed by John W. Gates ("Rothchilds to buy mines. . . September 5, 1896 sale for $10,000,000," Arizona Silver Belt, 16 April 1896; "Rothchilds buy Amarillas, Gran Central, Crestón, Minas Prietas, La Colorada," The Oasis, 26 August 1896). Besides these large-scale operations, the areas around the mines also included over one hundred separate mining claims operated by Mexicans and foreigners. Firms like the Pan American Mining Company operated smaller diggings in nearby hills ("Pan American Mining Company," The Oasis, 31 August 1895), while others bought and reprocessed tailings from the Crestón Colorada. This arrangement allowed smaller, less capitalised enterprises to profit. workers received a combination of wages and coupons (boletas) which they redeemed for products at the two company-operated tiendas de raya, the Prietas Store and the Gran Central Stores. Despite charging inflated prices for most basic items, the availability of credit continued to attract many workers. To circumvent the tienda de raya, many labourers began falsifying the boletasAMLC, Presidencía, caja 1, Justicia, 1898-1904, March, 1897. Antonio Madrid arrested for false boletas: a lucrative black market in counterfeit boletas plagued the Gran Central StoreThe Oasis, November 13, 1897 and it abandoned the system after 1897 and paid its workers in cash.

In May 1900 a newspaper reported that the tienda de raya in Minas Prietas bought in the chits (fichas) with which workers were paid at a 25% discountEl Amigo de la Verdad, Puebla, 5 May 1900 whilst another newspaper stated that they had replaced the fichas with boletos “The Mexican government has notified the company store at La Colorada that the issue of "fichas," or tokens exchangeable for goods, is an act of government the same as coining money, and prohibited the practice. As a result the workmen who go to the store with their pay "boletos" take the goods directly, without using the "fichas," the rule being to punch from the "boleto" not less than one dollar in value and supplying goods to that amount. Under the old system the "fichas" were given when the “boleto” was presented, and the workman took the goods when he wanted them, exchanging the "fichas" therefor.” (The Oasis, Nogales, 9 June 1900).

La Dura

In 1912 the miners at La Dura went on strike because of the exhorbitant prices at the tienda de raya and the fact that they were paid monthly. They returned to work when the company agreed to fortnightly payments and to reduce the prices in the tienda de rayaLa Gaceta de Guadalajara, 7 April 1912. The newspaper article places La Dura in Cananea, but it is in fact in Rosario.
