Mining Operations Red Lake

mining operations red lake

       Red Lake is located within one of the world’s most prolific gold camps, located approximately 230 kilometres northwest of Dryden, Ontario. Goldcorp’s active mining operations covers approximately 2,335 hectares and is accessible by Highway 105, which heads north from the Trans-Canada Highway. Daily commercial air services connect the numerous local communities to both Thunder Bay and Winnipeg. Red Lake, Canada. Located in one of the world’s most prolific gold districts, Red Lake is one of Goldcorp’s top producers, yielding 414,400 ounces in 2014. The High Grade Zone is the backbone of mining operations red lake , with an average grade of more than two ounces of gold per tonne. Recent investments in infrastructure and development have positioned this renowned mine for many more years of long-term sustainable production.
      Operations gold mining Red Lake and gold mining process are situated in the eastern part of the Red Lake Greenstone Belt in the Birch-Uchi Lake Subprovince of the Superior Province, within the core of the Canadian Shield. The Balmer Assemblage, which hosts the Red Lake Gold Mines, is part of the oldest sequence in the belt, consisting of a highly deformed Mesoarchean tholeiitic volcano-sedimentary complex, which locally plunges steeply to the southwest. This folded volcanic package is in contact with the main regional unconformity up against the Neoarchean sedimentary dominated Bruce Channel Assemblage.

operations underground mining at Red Lake     All operations underground mining at Red Lake is carried out by using three mining methods to maximum ore extraction: Overhand Cut and Fill (OCF), Underhand Cut and Fill (UFC), and Long Hole (LH). The high-grade zone mining operations red lake, which primarily consists of a narrow vein system, is mined at the rate of 450 tonnes per day with an average grade of over 45 grams per tonne (1.3 ounces per tonne). The high-grade mineralization and complex geometry of the ore body require specialized operations expertise.
Red lake gold ore
       Mineral ore types include silica replaced carbonate veins with free milling gold, siliceous replacement-type mineralization (rich with arsenopyrite) marginal to veins, broad disseminated sulphide mineralization along major shears, and some minor sulphidized chemical sediment-hosted ore.
gold leaching red lake      Innovative mining techniques and mining operations red lake have improved efficiency, such as a wet shotcrete system, the use of larger trucks, use of electric man carriers and a portable diamond drill mounted on a jumbo carrier. Mining operations red lake is supported by two mill processing facilities, providing a total milling capacity of 3,100 tonnes per day, including crushing, processing and pastefill plants. The processing plant’s operations consist of grinding, gravity concentrating, leaching, carbon-in-pulp (CIP), carbon elution and reactivation, electrowinning, bullion smelting/refining and cyanide destruction, flotation and concentrate handling—all of which are required to recover the gold in Red Lake’s ore types.
       The Cochenour/Bruce Channel deposit is key to plans for future consolidation. The work on enlarging and upgrading the existing Cochenour shaft is nearly complete. The development of a 6.0-kilometre haulage drift that will connect the existing Red Lake underground infrastructure with Cochenour is ~90% complete. The haulage drift will enable the efficient hauling of Cochenour/Bruce Channel ore to the Campbell mine for processing at the existing mill. The drift also opens up exploration of over six kilometers of untested ground in one of the world’s richest gold districts.
      Exploration in 2015 will continue to focus on the high-grade HG Young discovery. Rehabilitation of the 14-Level access in the Campbell Complex is completed underground drilling has commenced and will continue throughout 2015. Exploration drilling will also continue to focus on expansion of the R zone, NXT zone and the High Grade Zone (HGZ) up-plunge and at depth.
