Lincoln’s twelfth drill hole was the first to intersect the MBX Zone in 1987. Tyler Buckingham, P.Eng.

Milligan Property - Northern BC - Prepared for Terrane Metals Corp. April 2008 www.terranemetals.com). Minor post-mineral carbonate alteration is also present.

The WBX zone and its downfaulted western extension, the DWBX zone, form the northwest portion of the deposit. Houle completed the job under extreme conditions and scheduling delays. Phase 3 mining of the MBX pit continued with some modification such that mining in the gold-rich 66 zone began earlier than previously scheduled, and Phase 4 was to start by year end. The trachytic rocks are porous and intensely potassically altered. Placer Dome Inc. purchased the property in 1990, did extensive infill and step-out drilling, and completed a pre-feasibility study in 1991. In 2007, the company reported an estimated 213.8 million tonnes grading 0.228 per cent copper and 0.472 gram per tonne gold. The veins contain mostly pyrite with lesser chalcopyrite, sphalerite, galena, molybdenite, arsenopyrite and tetrahedrite-tennantite, and minor quartz, potassium feldspar and carbonate. BC Region* SelectVancouver & Lower MainlandVictoria & South IslandNanaimo & North IslandKamloops & Nicola ValleyKelowna & Okanagan ValleyPrince George & BC NorthKitimat It includes sphene-bearing monzonite, with gabbro and hornblende granite end members; and porphyritic granite. Extensive geological, geochemical, lithogeochemical, magnetic, IP and trenching work was done by BP until 1986, when Lincoln Resources Inc. optioned the property.

In the Mount Milligan area, the Takla Group has recently been divided into four informal units: the Upper Triassic Rainbow Creek, Inzana Lake and Witch Lake formations and the Lower Jurassic Chuchi Lake Formation (Fieldwork 1990, page 93). Supergene alteration in the deposit is recognized in the MBX, WBX and Southern Star zones. David Banks. The carbonate-quartz rich veins, which contain sphalerite, galena and pyrite, occur in propylitically altered latitic volcanics northwest and northeast of the MBX stock. Prominent east-northeast striking crossfaults are the latest episode of faulting in the area.

Between 2006 and 2007, Terrane completed 18,507 metres of drilling in 60 holes with the purpose of upgrading the mineral resources. Having a crew from all regions of Canada posed transportation challenges as well. The mine is a conventional truck-shovel open-pit gold copper mine. Mill throughput then averaged about 52,800 tonnes-per-day over the first three quarters of the year. Its wallrocks and numerous pendants include regionally metamorphosed amphibolites and granulites as well as contact hornfelses. The area was prospected as early as 1937, but no serious work was done until 1972 when Pechiney Development Ltd. conducted induced polarization (IP), geochemistry and a five-hole drill program. Contact Name* Milligan Project, Stage 1 Report, Volume 1 - Development Plan (Mine Development Review Process), April 1991, Placer Dome Inc., Table 3.4, page 3-12). In 2016, Mount Milligan mine saw its third full-year of operations. This email address is being protected from spambots. The Mount Milligan mine is located 8.75 kilometres south-southeast from the summit of Mount Milligan and 7.75 kilometres west from Philip Lakes, approximately 157 kilometres north-northwest of Prince George. In 2017, Proven reserves stood at 256.8 million tonnes at 0.187 per cent copper and 0.424 gram per tonne gold; Probable reserves at 239.4 million tonnes at 0.188 per cent copper and 0.293 gram per tonne gold. Mount Milligan is a copper-gold mine located 155km northwest of Prince George. The company also reported a combined Measured and Indicated mineral resource of 590.8 million tonnes grading 0.193 per cent copper and 0.352 gram per tonne gold (Feasibility Study - Technical Report Mt. The crew also had to work around a mine site that posed some hazardous conditions. Canada. The Mt. Mount Milligan mine is located 90 km North of Fort St. James. The Mount Milligan deposits are made up of the Main and Southern Star (093N 191) deposits. Twenty core specimens were collected for polished thin section examination and 26 samples were analyzed. The Mount Milligan deposit has a measured and indicated resource of 445 million tonnes of ore grading 0.415 gram per tonne gold and 0.215 per cent copper. Challenges A pre-feasibility study in 1991 estimated the mineable reserve at 298,400,000 tonnes of ore grading 0.45 gram per tonne gold and 0.22 per cent copper (Information Circular 1995-1, page 14). document.getElementById('cloak6154').innerHTML += ''+addy_text6154+'<\/a>'; We build each detailed map individually with regard to the characteristics of the map area and the chosen graphic style. The MBX stock is a moderately west dipping monzonite body approximately 400 metres in diameter. It is the first major new metals mine built in British Columbia in the last ten years.

Being 155km away from Prince George meant figuring out how to transport crew members and materials three hours onto site via a logging road. By mid-October, nine shipments of approximately 12,500 dry tonnes of copper-gold concentrate had been made; with 150,000 dry tonnes expected to be shipped by year end. Both occur along the hangingwall of the MBX stock, and contains gold and copper. Due to the nature of the work performed, Houle acquired lots of new tools and equipment as a result of the project, tools and equipment that can be used for future projects of this magnitude. In areas of potassic alteration, mineralization is developed best in monzonitic and volcanic rocks adjacent the footwall and, to a lesser extent, the hangingwall contact of the stocks. Efforts to optimize mine and mill operations and increase recoveries continued, including blast fragmentation and movement monitoring and ongoing geometallurgical modelling.
Mineralization consists mostly of chalcopyrite, lesser magnetite and minor bornite in areas of potassic alteration, and pyrite in areas of propylitic alteration. Secondary copper minerals identified in these areas consist of the sulphides, covellite, chalcocite and djurleite; the oxides, cuprite and tenorite; the carbonates, malachite and azurite; and native copper. Rio Tinto Aluminum Smelter – Kitimat Modernization Project. Pyroxene phenocrysts, where present, are replaced by actinolite.

Minor augite porphyritic flows and heterolithic debris flows are interbedded with the fragmental rocks. Mill throughput then averaged about 52,800 tonnes-per-day over the first three quarters of the year. In 2006, after Placer Dome was acquired by Barrick Gold Corporation, Terrane Metals Corp. purchased the property. Mining in the 66 zone on the hangingwall side of the southeast dipping Rainbow fault has confirmed a modelled repetition in zoned alteration and mineralization sequence.

Secondary copper minerals commonly occur with goethite, magnetite, hematite and siderite. Overlying epiclastic sediments of the Inzana Lake Formation are in turn overlain by augite and other porphyritic volcanics and pyroclastics of the Witch Lake Formation. A geological resource (no economic considerations) for the MBX and Southern Star zones is reported to total 1,153,135,000 tonnes grading 0.254 gram per tonne gold and 0.126 per cent copper (Mt. During 2008, exploration on the Mount Milligan property was limited to geochemistry and a HeliGEOTEM magnetic-electromagnetic survey. Pyrite and chlorite occur in the rock as curvilinear partings in a massive rock type, and along bedding planes and disseminated throughout in a bedded type. *8, Nov.30, 2015, Jan.14, 2016, Feasibility Study - Technical Report Mt. var addy6154 = 'info' + '@'; Offering 24-hour emergency services through our ten offices located throughout British Columbia,  we are dedicated to ensuring that your facility has the resources it needs to operate. 341-347, EMPR INF CIRC 1993-13; 1994-19, p. 14; 1995-1, p. 14; 2011-1, pp. Annual Report 2014). About 25 kilometres west-northwest of the Mount Milligan deposit is the southern tip of the northwest-elongate Late Triassic to Early Cretaceous Hogem Intrusive Complex. This addition is expected to increase average mill throughput to 62,500 tonnes-per-day or higher. The Rainbow Creek Formation is a basinal layer of slate, and lesser siltstone and epiclastic interbeds. In areas of propylitic alteration, mineralization generally decreases away from the stock.
