Avanti Mining Further Optimizes Kitsault Feasibility Study
(firmenpresse) - VANCOUVER, BRITISH COLUMBIA -- (Marketwired) -- 11/14/13 -- Avanti Mining Inc. (TSX VENTURE: AVT)(PINKSHEETS: AVNMF) ("Avanti") is pleased to provide the results of the most recent study to further optimize the February 2013 Feasibility Study Update ("FSU") prepared by AMEC on its 100% owned Kitsault Molybdenum-Silver property in northwest British Columbia, Canada. The optimization started with a new mine plan including new capital and operating cost estimates intended to bring cash flow forward thereby improving the project economics. This optimized FSU will become the basis for discussions with financial institutions regarding the projects debt and equity financing needs.
"We are pleased to present an optimized version of our 2013 Feasibility Study Update by AMEC and other contributors on the Kitsault Molybdenum Project," stated Mark G. Premo, Avanti's President and CEO. "Kitsault's projected cash costs are in the lowest quartile of primary molybdenum producers worldwide."
Because there were no material changes to mineral reserves or mineral resources, the technical report summarizing this update will be filed with Avanti's Annual Information Form on SEDAR and Avanti's web site, in the second quarter of 2014. All economic figures contained in this press release are expressed in Canadian dollars except where noted (USD exchange rate varies in the model between 0.95 to 0.93 per CAD$, details are provided in table 4).
Highlights of the project include:
Optimization approach
Early in 2013 Avanti engaged a group of engineering and consultancy firms including Whittle Consulting, Ausenco, AMEC and Knight Piesold to further optimize the Kitsault Molybdenum Project. The optimization initiative is aimed to rationalize the initial capital expenditure while providing higher returns in early stages of the project as well as the maximization of metal recovery at the later stages. The main aspects incorporated into the project as part of the optimization include:
Project Description
The Kitsault property is located about 140 km north of Prince Rupert, British Columbia, and south of the head of Alice Arm, an inlet of the Pacific Ocean. The property includes three known molybdenum deposits: Kitsault, Bell Moly, and Roundy Creek. The Kitsault mine was a producer of molybdenum between 1967 and 1972 and from 1981 to 1982 with total production on the property during both periods being approximately 31 million pounds of molybdenum.
Kitsault has road access to the mine site and is serviced by the BC Hydro transmission grid. The November 2013 FS update estimates that the Kitsault Mine would operate at an annual mill throughput rate of 16.6 million tonnes, or 45,500 tpd, with an average strip ratio of 1:1 for a mine life of 14 years. The ore mined by conventional truck and shovel open pit methods will be crushed in a gyratory primary crusher, then ground using a SAG-ball mill configuration. Conventional flotation and five stages of cleaning will produce molybdenum concentrate that will be dried and packaged into bags for shipment. The life-of-mine molybdenum production is estimated at 367 million pounds of molybdenum contained in approximately 343 thousand wet tonnes of molybdenum concentrate produced from the processing of 226 million tonnes of ore grading 0.083% Mo. Total molybdenum recovery varies depending on mill head grade but is estimated to average 89% over the life of the mine. During the de-sulfidization of the tailings for environmental considerations, a process was developed to recover by-product silver that averages 5.3 g/t in the mill feed. Silver production of 15.2 million ounces is indicated at a metallurgical recovery of approximately 39%.
Mineral Reserves Statement
The Kitsault mine Mineral Reserves have been prepared by the consultants in accordance with NI 43-101 standards and CIM Definition Standards (2010). This statement was prepared by Mr. Ramon Mendoza Reyes (P.Eng.) of AMEC, a Qualified Person (QP) as defined in NI 43-101. These reserves are sufficient for 14 years of operation at a nominal production rate of 45,500 t/d. Mineral Reserves are summarized by category in Table 1. The notes accompanying Table 1 are an integral part of the Mineral Reserves and should be read in conjunction with the Mineral Reserve statement.
Notes:
Capital Costs
Initial capital costs are estimated at $812 million compared with $938 million in the February 2013 update to the FS for a reduction of approximately 14%. Life-of-Mine sustaining capital (including reclamation bonding) was estimated to be $166 million, which is comprised mainly of mobile mine equipment replacement, ongoing Tailings Management Facility ("TMF") embankment construction. This compares with $106 million in the 2013 update for an increase of about 56%. All capital costs are (+/-15%) accuracy in this estimate.
The capital costs for the mine, plant and TMF and comparison with the February 2013 FSU are given in Table 2 below.
Operating Costs
LOM cash mine site operating costs are estimated at $6.58 per pound of Mo (+/-15% accuracy). Total cash cost are $7.07 per pound of Mo, this includes a silver credit of $0.98 and transportation and smelter charges of $1.47. These costs are about 3% higher than the February 2013 FS Update. The LOM unit cash operating costs are also summarized in Table 3 below:
Project Economics
The Feasibility Study economic results utilized assumptions summarized in the Table 4 below:
The economic model for the base case in this study update assumes a long-term average molybdenum price of $14.50/lb for revenue purposes.
The after-tax NPV at an 8% discount rate over the estimated mine life is $417 million. The after-tax IRR is 17.3%. Payback of the initial capital investment is estimated to occur in 4.4 years after the start of production.
Sensitivity
Sensitivity analysis for key economic parameters is shown in Table 5. This analysis suggests that the project is most sensitive to exchange rates followed by Mo prices. The project is least sensitive to operating and capital costs.

The financial model also examines the primary financial outputs at various LOM realized Mo prices and various discount rates. These results are displayed in Table 6.
Financing and Environmental Assessment Update
Avanti continues to advance its strategy to finance the development of the Kitsault Mine. Toward that end it has signed an off-take agreement with ThyssenKrupp Metallurgical Products, a German steel maker, for 50% of the production of Kitsault for the life of the mine. Contract volumes will be established annually based upon the mine plan and reference a market based monthly price for molybdenum. Based upon the strength of this off-take agreement and an application made by KfW IPEX-Bank GmbH (KfW), a member of Avanti's mandated banking syndicate, the project has received approval in principle for German government debt guarantee for up to US$300 million.
Avanti also continues discussions with a potential strategic partner that will assist in providing the equity component of the project financing.
The Project received the BC Environmental Assessment Certificate in March 2013 and subsequently applied for the British Columbia permits for construction in April 2013. The permitting process is well advanced and the permits are expected by the end of this year. The Kitsault Project went through a comprehensive study as required by the Comprehensive Studies Regulation of the Canadian Environmental Assessment Act (CEAA), with key triggers being the requirement for a Fisheries Act permit and explosive permit under the Explosives Act. The federal review of Avanti's Environmental Impact Statement (EIS) was completed on September 22, 2013. The federal Minister of Environment will render a decision on the EIS before the end of 2013.
