Comments on the workings information

  • Underground workings included an inclined shaft from which the deposit was worked laterally for 125 feet and more than 1700 feet down dip.

Comments on other economic factors

  • From 1918 to 1970, the combined Delano and Cleveland mine deposits produced 46.7 tonnes of silver, 10 kilotonnes of lead, and 0.6 kilotonnes of zinc from an unknown tonnage of ore.
    In 1980, the combined Delano and Cleveland mine deposits were estimated to contain reservesof 240 kilotonnes of ore grading 6.43 opt Ag, 5.6% Pb, 3.8% Zn, with minor Cu and Au.
    In 1989, the combined Delano and Cleveland mine deposits were estimated to contain a remaining resource of 218 kilotonnes of ore containing 48 tonnes of silver, 12 kilotonnes of lead, and 8 kilotonnes of zinc (Long and others, 1998).

Comments on development

  • The first activity in the area was an ore discovery by an indian who showed it to Thomas J. & Brown in spring of 1872. The district was organized as the Goose Creek district at this time. Supposedly some 90 locations were made, with the main properties being Cotton Thomas, Anna Carroll, and Providence. (Whitehill, 1875, 1877). The Servia and Slavonia Mining Co. Waw incorporated to work the mines. Activity then waned with decline in silver price. About 1905, Craig Chambers mined and shipped ore from the Gold Note other mines until the lead-silver declined and he abandoned the effort. It was inactive until about 1917 when Roy Woods, and C.B. Whinery & Associates began work on the Delano claim. They shipped ore to Salt Lake City 1917-20. The Delno mine was a steady shipper for 10 years through 1926 with 30-50 car loads a year. In 1925 a 20-ton concentrator was erected on Rock Spring Creek 7 miles west of the mine. (Hunt), later this was enlarged. Panther Mines Co. incorporated with stock to lease and option the Delno Mine and Milling Co. but ran into financial problems. Next the Net or Delno Co. worked the property successfully for about 15 years. The replacement deposits in limestone averaged 20-25% Pb & 30-35 oz. Ag per ton. Shipping ore ran 50% Pb, 60 oz. Ag.; Mill ore averaged 15% Pb and 20 oz Ag per ton. The main ore shoot (1937) was 300 ft long on a 30 incline, and 13 ft wide and uniform. The property was developed by a 1,200 ft incline shaft (at this date). One half the tonnage was milled at the company mill at nearest water source (Rock Springs Creek). Haulage charges were high-ore hauled out and water hauled in. Production reported to be about $300,000 for the 15-year period. Granger, 1957 reported the mine to have 5,900 ft of underground workings (sans stopes)-laterally to 125 ft and 1,700 ft down dip of ore zone. Ore is off-set with several faults. Deterrents to profitable operation were poor ventilation, ore handling, and poor condition of incline shafts. The Delno or Delano mine continued to work through the WWII years up until 1960s with a steady production. It was owned and operated by the Delno Mining Company in the 1960s. At that time the workings included 6,200 ft, with a down dip distance of 1750 ft. Noranda Exploration, Inc. was exploring the property in 1990.

Deposit The deposit is a replacement of favorable limestone beds, controlled by faults. The ore rakes 65 NW, strikes N, and dip 25-43W. The most productive bed has been the "upperbed". High angle faults terminate the ore body both on the north and south .
