TIGHTNER IS A GREAT MINE.
JUN. 22, 1911
Recent ore shipment brings large returns. Woodbury’s Red Star also is in the running. W.H. Bourns income is one thousand daily
Alleghany (cal.) Jun. 20, the recent rich shipment of ore, amounting to 1200 pounds, pulled from Tightner mine Yielded the owners $75,000 in fine gold and 400 ounces of concentrates valued at $12 per ounce, making a total of $79,000. This ore was extracted in the course of developing the main vein in the lower adit, and was not taken out with the purpose of showing the richness of the mine. At this rate a ton of Tightner ore would yield about $130,000. The ore was treated at the Red Star mill and the concentrates sent to Selby’s. More rich quartz is being stored and it is reported that a sound crushing will be made before spring sets in.
Developments in the lower adit are progressing with renewed vigor and the drift, which is being driven to intersect the rich shoot opened in the winze, is rapidly approaching its objective. As far as opened the vein shows high milling values. Manager H..L. Johnson states that a mill will be erected during the coming summer, and mining men familiar with the Tightner, expect the property to become one of the greatest gold producers in California. The developments of the past half-year have opened up extensive ore reserves, and the remarkable richness of the hulk of the ore insures splendid profits for the owners.
Johnson originally secured the Tightner for a few thousand dollars, and within a short time of taking charge uncovered ore that paid off all costs and left an excellent profit. Last summer a German syndicate made an offer of $2,500,000 for the property, but Johnson refused to consider negotiations unless a cash payment in full was made at once. The Germans desired an option, but this was refused.
The Tightner has been developed to its present state by means of hand drills, but within a short time, a compressor will be installed and power drills operated. The recent introduction of electricity into the district marks a new epoch in the famous old field.
The strike recently made at the Red Star continues to show up splendidly and manager Woodbury is confident that the property is destined to become one of the foremost producers of the district. The ore shows the same value that marks the Tightner vein, and appears to be an extension of the famous Tightner-Rainbow vein system. Little attention is being paid to ore production at this time; the company is concentrating every effort on developments.
The Rainbow, Plumbago, and Bear Creek mines are maintaining an excellent production, and the twenty-stamp mill at the Plumbago are treating excellent ore, coming mainly from no. 4 adit where splendid ore is being stopped. This property is the largest producer in the district, and is a consistent dividend disburser. The Rainbow has maintained a steady yield throughout the year and enters upon 1911 with every promise of a profitable season. The Bear Creek is rapidly coming to the front as one of the best properties in the district. It is estimated that the1910 yield of Alleghany will run about $300,000 and that in 1911 the yield will exceed the $1,500,000 mark. This increase is certain, if present plans of various companies are carried out.
It is reported that the South Fork Mining Company and the Rio Antigue Company of Los Angeles have locked horns over the South Yuba Placer Property in Forest. It is rumored that the South Yuba people seized the mine, which is under bond to the Angelenos. Information is difficult to obtain regarding the trouble, but it is expected that a compromise will be effected. The Angelenos have been conducting developments for several years, during which time they expended approximately $60,000 in extending adits and driving raises and crosscuts. It was reported some time ago that the company had struck the rich channel, and it is supposed that the friction developed from this source.
PLACER MINES ACTIVE
The recent bountiful rains and snow have started the placer companies at work throughout the northern counties, and the gulches of Siskyou and Trinity are re-echoing to the music of the giants. Several Los Angeles companies are operating in Siskyou, and in every way a profitable season is anticipated. The famous La Grange, Union, Douglas City and similar properties are operating at full capacity. In Plumas County the Neocene Mining Company of Los Angeles has its giants in action and is landing large quantities of rich gravel. In Oregon, just across the line from Siskyou County, Los Angeles companies are operating rich hydraulic mines. During the year of 1910 many of the best placer producers along the California-Oregon line passed into the hands of Angelenos, and the winters run promises to be unusually profitable to investors from the angel city.
EMPIRE CROWDS NORTH STAR.
According to excellent authority, the Empire mine at Grass Valley produced approximately $1,250,000 in 1910, placing it on a level with the noted North Star group. The Empire is a close corporation and withhold all information from the public, but those in a position to know assert that W.H. Bourn, the principal owner, is receiving an income of fully $1,000 per day from the great property. The company recently installed a cyanide plant at an approximate cost of $40,000 and is saving values from tailings formerly regarded as practically worthless.
THREE FURNACES AT MAMMOTH
The Mammoth Copper Company has blown in its third furnace, and the bag house is successfully handling the fumes. The Company plans to keep all three furnaces in commission during the cold weather, and it is understood that the capacity of the bag house will be augmented before warm weather sets in. The company is receiving large consignments of custom ore, in addition to the shipments from its own properties. Two furnaces still remain idle, and it is unlikely that these will be blown in until a marked change develops in the copper situation.
CALAVERAS COPPER SUSPENDS
The Calaveras Copper Company has suspended operations greatly to the surprise of the mining world. The company recently installed expensive equipment, largely augmented its smelting and concentrating facilities and prosecuted vigorous developments. Enormous quantities of ore were blocked out and announcement made that with the dawn of 1911 the smelter would commence a monthly-production of 1,500,000 pounds of mister copper. No reason has been given for the sudden closing of the mines, but the manager states that orders have been received to keep the pumps in action. This indicates that the company will probably resume in the near future.
It is reported at Jackson that he main ore body has been intersected on the 2600 level of the Central Eureka mine. It is said that the vein is large and runs $8 per ton in free milling gold ore. The mine adjoins the South Eureka and is expected to become an active producer at an early date, as the rich ore bodies of the South Eureka are supposed to extend through Central Eureka estates.
PROMISING RIVERSIDE MINE
The recent rich strike at the Calzona mine, in Riverside County, seventeen miles from Parker, Arizona, is attracting much attention. The vein is seven feet wide with samples running $200 per gold, with high copper contents. The Calzona is shipping ore to the Humboldt smelter. The Sanborn is also shipping ore, and the Steece is expected to make its first shipment by the end of the month. The mines are located on Riverside Mountain, and promise to become the most important in the Southern section of California. Developments are active at all three properties.
