Consolidated Nevada Goldfields Corporation announces fiscal 1997 first quarter results and details Mexican acquisition.DENVER--(BUSINESS WIRE)--Nov. 8, 1996--The first quarter of fiscal 1997 culminated in significant advances for the Company. On October 10, 1996, four operating silver, gold, copper and barite barite (bâr`īt), barytes (bərī`tēz) [New Lat., from barium], or heavy spar, a white, yellow, blue, red, or colorless mineral. mines in Mexico were acquired from former owner Grupo Real del Monte Real del Monte (officially Mineral del Monte) is a small town and municipality in Hidalgo state in central Mexico, lying at an altitude of 2700 metres (8,800 ft). for more about Real del Monte visit [1] History S.A. de C.V. Simultaneous with the closing of this acquisition, a related US$20 million special warrants financing was completed. With the completion of these transactions, the Company moves confidently into the international mining arena. Now, with six producing mines and over 1,500 employees, the Company counts among its resources proven and probable reserves of approximately 600,000 ounces of gold, 47 million ounces of silver, 28 million pounds of copper and 4 million tons of barite. Total gold equivalent geologic resources are 4.8 million ounces. The combined Company is projected by independent engineers to double its productive capacity as a result of the Mexican acquisition. It represents an impressive beginning to fiscal 1997. Here is a brief overview of each of the mines acquired: -- Pachuca - a gold and silver mine which has been in continuous operation for over 465 years producing over 1.2 billion ounces of silver and 6 million ounces of gold. Pachuca is currently operating at less than half capacity and the Company is planning on restoring the mine to its full potential and exploring the 116,000 acre Pachuca district which the Company now owns virtually in its entirety. -- El Baztan - a 500-ton-per-day operating copper and gold mine which currently has average grades of 1.8% copper and over 43,000 acres of exploration land. -- Magistral mag·is·tral adj. Prepared as specified by a physician's prescription. Used of medicine. del Oro - currently reprocessing Reprocessing may refer to:
-- Barita de Sonora - a barite mine which sells high-quality barite to the petroleum industry which currently has in excess of 10 years of reserves. During the quarter, at its U.S. mines, the Company sold 10,172 ounces of gold compared to 4,860 ounces of gold sold during the comparable quarter of 1996. The Company reported a net loss of $2,543,000 on revenues of $3,565,000 compared to a net loss of $227,000 on revenues of $1,697,000 for the comparable quarter of the prior year. Included in the quarter's net loss are non-cash charges of $1,425,600 in depreciation, depletion and amortization and $242,000 in the continuing write-off of a hedging agreement terminated in a prior period. Also included were $474,000 in finance charges. The increase in the loss was primarily a result of temporary mining sequencing delays and equipment downtime due to major overhaul programs at the Nixon Fork mine in Alaska. General and administrative costs administrative costs, n.pl the overhead expenses incurred in the operation of a dental benefits program, excluding costs of dental services provided. continued to be high due because of activities related to the Grupo Real del Monte acquisition. PACHUCA In acquiring the Pachuca mine, the Company inherits half a millennium of extraordinary mining history. The Company now owns 100% of the Pachuca underground mine complex, mill, refinery, considerable real estate holdings in the city of Pachuca and the mining concessions covering the entire Pachuca mining district, including over 116,000 acres of highly prospective exploration ground. The mine is in operation and employs 1,043 people. Last year Pachuca produced 1.6 million ounces of silver, 7,100 ounces of gold, 223 tons of zinc and 29 tons of lead from its 3,000-ton-per-day flotation/cyanidation mill. Pachuca owns and operates the only precious metals Precious Metals Valuable metals such as gold, iridium, palladium, platinum, and silver. Notes: Investing in precious metals can be done either by purchasing the physical asset, or by purchasing futures contracts for the particular metal. refinery in Mexico, producing 99.99% pure gold and silver with a Comex fair delivery silver grade stamp. All of the silver and gold mined at Pachuca is refined on site through this facility. Pachuca is currently producing at less than half capacity. In concert with Denver-based engineering company, Pincock, Allen & Holt, a comprehensive investment plan has been designed to restore the mine to its full capacity of six million ounces of silver and 30,000 ounces of gold per year. The majority of this plan is to be implemented over the next two years at a total estimated capital cost of $27.7 million, the bulk of which is to be spent in shaft sinking shaft sinking, excavation from the surface of an opening in the earth.

In addition, minor equipment upgrades and replacements will be made in the mill. Exploration at Pachuca The Pachuca mine exploits two intersecting quartz vein systems trending west-northwest and north-south. These veins are generally steeply dipping with widths ranging from 0.3 meters up to 15 meters at some localities in the district. Despite its 465 years of operation, very significant potential exists for the discovery of new veins and deposits on extensions of the known veins. In addition, the El Chico/Zumate area to the north of the existing mine is truly a world class exploration target with an areal extent three times that of the historic workings at Pachuca. Fifteen hundred meters of underground exploration and approximately 200 diamond drill holes in this area have just begun to define the extent of its potential. In the process, drill-indicated and inferred resources of 3.6 million tons have been established at an average grade of 8.7 ounces of silver and 0.07 ounces of gold per ton for a total of 31 million ounces of silver and 250,000 ounces of gold. This significant area will have a high priority in future district exploration plans. MAGISTRAL DEL ORO At Magistral del Oro, the Company processes tailings from a mine which produced approximately 700,000 ounces of gold during its 100-year life. The gold-bearing tailings are "mined" then agglomerated agglomerated of particles, compacted together into a mass. agglomerated feeds particulated feeds compacted or extruded into pellets and similar forms. and stacked for heap leaching Heap leaching is an industrial mining process to extract precious metals and copper compounds from ore.

Gold recovery is achieved using conventional cyanide leaching of the heaps and ADR ADR - Astra Digital Radio technology (adsorption adsorption, adhesion of the molecules of liquids, gases, and dissolved substances to the surfaces of solids, as opposed to absorption, in which the molecules actually enter the absorbing medium (see adhesion and cohesion). using activated carbon, desorbtion by higher strength cyanide solutions, and recovery in electrolytic cells). Reserves remaining are 1.45 million tons at a grade of 0.066 ounces of gold per ton, sufficient to sustain the operation for 3.6 years at the current production rate. The Company is currently evaluating a 30% increase in the production rate which would reduce the operating life to 2.5 years. Exploration at Magistral del Oro Recent limited exploration at Magistral del Oro has identified a resource of 745,000 tons at a gold grade of 0.142 ounces of gold per ton (106,000 contained ounces), dominantly in quartz veins similar to that mined in the past. In addition, this work has identified two areas of disseminated gold mineralization Mineralization The process by which the body uses minerals to build bone structure. Mentioned in: Rickets mineralization, n the bioprecipitation of an inorganic substance. . The best explored of these has surface samples averaging 0.06 ounces of gold per ton in an area measuring 330 feet by 130 feet. The disseminated mineralization in both areas is associated with silica and iron oxides, suggesting pipe-like epithermal bodies with significant tonnage potential. BARITA DE SONORA At its Barita de Sonora operation, the Company manufactures two high density barite products: 1) granular barite for use in oil well drilling Well drilling is the process of drilling a hole in the ground for the extraction of a natural resource such as ground water, natural gas, or petroleum. Drilling for the exploration of the nature of the material underground (for instance in search of metallic ore) is best described additives; and, 2) on demand, small lots of fine-milled barite for various custom applications. Most of the granular barite is sold to PEMEX Pemex officially Petróleos Mexicanos Mexico's state-owned oil company. In 1938 Pres. Lázaro Cárdenas nationalized 17 foreign oil companies to create Pemex, the largest Latin American petroleum company and a major world exporter of fossil fuel. , Mexico's national petroleum company. The barite is mined from deposits in Paleozoic sedimentary rocks (Geol.)

Processing consists of crushing the ore, followed by jigging (gravity concentration) to ensure the minimum specific gravity specific gravity, ratio of the weight of a given volume of a substance to the weight of an equal volume of some reference substance, or, equivalently, the ratio of the masses of equal volumes of the two substances. required by the customer. Current reserves of 4.4 million tons are sufficient for a mine life in excess of 12 years at the current production rate. However, as mining moves away from the plant, increased haulage costs will impact the profitability of the operation. As a result, emphasis is being placed on exploration for deposits on trend in alluvium al·lu·vi·um n. pl. al·lu·vi·ums or al·lu·vi·a Sediment deposited by flowing water, as in a riverbed, flood plain, or delta.

At the Vista Hermosa Vista Hermosa means "beautiful view" in Spanish and may refer to:

He studied rhetoric under Cassius Longinus and philosophy under Plotinus. . The El Arroyo area produces from a vein cutting the andesitic rocks. The ore from both deposits is processed by conventional flotation in a 500-ton-per-day plant to produce a copper concentrate with minor gold and silver credits. Total proven and probable mineable reserves for El Baztan are 734,000 tons averaging 1.92% copper (28.2 million contained pounds of copper). Of this total, 614,000 tons at 1.75% copper (21.5 million pounds of contained copper) are in the Vista Hermosa deposit, and 120,000 tons at 2.81% copper (6.7 million pounds of contained copper) are in the El Arroyo vein. During 1995, the El Baztan operations mined and processed 126,000 tons of ore. Exploration at El Baztan Underground diamond drilling Diamond Drilling is a highly specialized industry used for mineral exploration around the world. Most commonly using wireline and core bits with diamond encrusted matrix. To drill holes to max depths of twelve thousand feet, for the recovery of core used in verifying mineral has outlined an additional inferred resource of 507,000 tons at 1.50% copper. Indications are that there is a high probability that further drilling of this resource could nearly double the Vista Hermosa reserves. Analysis of historic production data has outlined a potential high grade ore shoot in the El Arroyo area at the intersection of several productive structures. This is the target of ongoing underground exploration. NIXON FORK MINE During the quarter, Nixon Fork sold 7,525 ounces of gold and experienced lower (1 oz/ton) grades. This is projected to be a temporary phenomenon caused by delays in underground development accessing higher grade orebodies in the mine. These delays were attributable to adverse ground conditions and equipment availability. These orebodies have now been accessed, are being developed for production, and are projected to increase the average grade, thereby increasing production and reducing operating cash cost. In addition, the operation experienced downtime caused by temporary cessations in production in the mill in order to perform equipment overhauls and to re-line the grinding mills. Exploration at Nixon Fork Nixon Fork Mine Site Exploration drilling at the Nixon Fork mine has very significantly extended the C3000 orebody and discovered two new potential orebodies: -- An underground drill hole (96U043) drilled down plunge to test the extent of the C3000 orebody at depth intersected two significant down plunge extensions: -- 82 feet at 1.846 ounces of gold per ton from 236 feet to 318 feet -- 92.5 feet at 1.139 ounces of gold per ton from 358.5 feet to 451 feet These intersections demonstrate an additional 280 vertical feet of new mineralization below the current level of mining (3000E stope stope n. An excavation in the form of steps made by the mining of ore from steeply inclined or vertical veins. tr.v. stoped, stop·ing, stopes To remove (ore) from or mine by means of a stope. ). Because the original vertical extent of the 3000 orebody was only 177 feet and has produced over 43,000 ounces of gold, we expect to add important new reserves in this area. -- Several drill holes in the C3300 deposit encountered higher grade intersections, including: -- 5.9 feet at 3.464 ounces of gold per ton -- 25.3 feet at 1.006 ounces of gold per ton -- 34.8 feet at 1.710 ounces of gold per ton These intercepts demonstrate that the new C3300 mineralized min·er·al·ize v. min·er·al·ized, min·er·al·iz·ing, min·er·al·iz·es v.tr. 1.

District Exploration District-wide exploration at Nixon Fork has identified several areas of gold mineralization which the Company believes may extend the geologic resources. -- Four drill holes in the intrusion demonstrate that previously defined gold-in-soil anomalies are associated with zones of extensive auriferous au·rif·er·ous adj. Containing gold; gold-bearing. [From Latin aurifer, gold-bearing : aurum, gold + -fer, -fer. alteration. The best drill hole (NR96-03) intersected mineralization averaging 0.03 ounces of gold per ton from 37 feet to 145 feet, including 0.19 ounces of gold per ton from 62.5 to 69.0 feet and 0.12 ounces of gold per ton from 138.5 to 145 feet. The drill hole penetrates a coincident magnetic and gold-in-soil geochemical anomaly 3,000 feet long and up to 1,000 feet wide, suggesting significant potential for the delineation of a large, bulk-mineable, intrusion-hosted gold deposit on the Company's property. -- A soil geochemical survey in the Eagle Creek Eagle Creek may refer to: A number of locations in Saskatchewan, Canada:
-- Analysis of airborne geophysical survey data indicates that ore-grade skarn mineralization has a unique combined magnetic-electromagnetic (EM) signature. Detailed evaluation of the data set, which covers all the Company's holdings in the area, for this signature should enhance the success rate of exploration drilling. AURORA MINE During the first quarter of fiscal 1997, Aurora sold 2,647 ounces of gold compared to 3,782 ounces of gold during the same period of fiscal 1996 as a result of low grade ore which as part of the mine plan was scheduled to be shipped to the mill. Despite a highwall failure earlier in the year, the mine experienced better than budget performance in tons milled, direct costs and recoveries. Work continued on the definition of the Martinez deposit discovered during 1995. The Company completed over 38,000 feet of drilling which has established a resource of 1.16 million tons at a grade of 0.092 ounces of gold per ton for a total of 104,000 ounces of gold. Better results from the ongoing drilling of the deeper portions of the Martinez deposit included true widths of: -- 30 feet at 0.20 ounces of gold per ton -- 82 feet at 0.26 ounces of gold per ton -- 10 feet at 0.49 ounces of gold per ton -- 45 feet at 0.15 ounces of gold per ton -- 36 feet at 0.33 ounces of gold per ton The Company plans on completing an internal feasibility study of the Martinez deposit during the second quarter of the fiscal year. BARITE HILL The reclamation of Barite Hill continued during the quarter with evaporation of the main pit water, and revegetation Revegetation is the process of replanting and rebuilding the soil of disturbed land. This may be a natural process produced by plant colonization and succession, or an artificial (manmade), accelerated process designed to repair damage to a landscape due to wildfire, mining, flood, of the completed clay caps of the main heap and waste areas. In addition, the Company began initial studies of on-site bioremediation bi·o·re·me·di·a·tion n.
