PolyMet Updates Technical Disclosure

01.11.2012  |  Marketwired

ST. PAUL, MINNESOTA -- (Marketwire) -- 11/01/12 -- PolyMet Mining Corp. (TSX: POM)(NYSE MKT: PLM)(NYSE Amex: PLM) ("PolyMet" or the "Company") has filed an updated Technical Report under National Instrument 43-101 ("NI 43-101") on its NorthMet copper-nickel-precious metals project located in the established Mesabi Iron Range mining district in northeastern Minnesota. The 43-101, dated October 12, 2012 has been filed on SEDAR and EDGAR and is on the Company's website at www.polymetmining.com.


Pierre Desautels, P.Geo and Gordon Zurowski, P.Eng of AGP Mining Consultants Inc. are Qualified Persons for the purposes of National Instrument 43-101 and has reviewed and approved the information of a scientific nature contained in this news release.


PolyMet News Release 2012-6 (June 14, 2012) reported that, in response to a routine review by the British Columbia Securities Commission ("BCSC") of the Company's continuous disclosure, PolyMet would update the NI 43-101 to incorporate the Definitive Feasibility Study ("DFS") prepared by Bateman Engineers in 2006, subsequent expansion of mineral resources and mineral reserves, modifications to the process flow sheet, and enhanced plans for protecting the environment.


Project Development Overview


With publication of the DFS in September 2006, PolyMet established SEC-standard mineral reserves. In September 2007, PolyMet reported an expansion in these proven and probable mineral reserves to 274.7 million short tons grading 0.28% copper, 0.08% nickel and 0.01 opt of precious metals (palladium, platinum and gold). These expanded reserves had not been described in a NI 43-101 compliant Technical Report, which has now been addressed in the October 2012 Technical Report.


At a Net Metal Value (NMV) cut-off of US$7.42, the reserves lie within measured and indicated mineral resources of 694 million tons grading 0.27% copper, 0.08% nickel and 0.01 opt of precious metals. In addition, inferred mineral resources total 230 million tons grading 0.27% copper, 0.08% nickel and 0.01 opt of precious metals.


The NMV is calculated using copper price at $1.25 per pound, nickel at $5.60 per pound, and precious metal prices of $210, $800, and $400 per ounce respectively for palladium, platinum and gold with refining, insurance and transport cost, recovery ore to concentrate and recovery concentrate to metal taken into account.

2008 DFS Update


On May 20, 2008 PolyMet reported revised processing plans and cost estimates for construction and operating costs that improve the economics and reduce the operating risks. The mine reserves were unaffected by these changes. The revised plans include:



-- the sale of concentrate during the construction and commissioning of new
metallurgical facilities resulting in a shorter pre-production
construction period (12-15 months) and reduced capital costs prior to
first revenues ($312 million versus $380 million) despite the inclusion
of an estimated $65 million of additional measures to protect the
environment;
-- the new metallurgical facilities to be constructed during initial
production and sales of concentrate. PolyMet anticipates that much of
the additional $290 million of capital costs (for total project capital
of $602 million) will be largely funded from cash flow from initial
operations;
-- mine plans (based on copper at $1.25 per pound) reflect the increase in
reserves and decrease in stripping ratio reported on September 26, 2007,
the use of 240-ton trucks, and owner versus contract mine operations,
and
-- $77 million of mining equipment, which was assumed to be provided by a
mining contractor in the DFS, has been incorporated as an operating
lease in updated operating costs.


Project Improvements


On February 2, 2011 the Company announced that it had further simplified the proposed metallurgical process, again with no change to the mine plan, and now plans to build the project in two phases:



-- Phase I: produce and market concentrates containing copper, nickel,
cobalt and precious metals, and
-- Phase II: process the nickel concentrate through a single autoclave,
resulting in production and sale of high grade copper concentrate, value
added nickel-cobalt hydroxide, and precious metals precipitate products.


Previous plans included a second autoclave and a copper solvent extraction/electro-winning ("SX-EW") circuit to produce copper metal along with value added nickel-cobalt hydroxide and precious metals precipitate products. The changes reflect continued metallurgical process and other project improvements as well as improved environmental controls that are being incorporated into the environmental review process. The advantages, compared with the earlier plan, include a better return on capital investment, reduced financial risk, lower energy consumption, and reduced waste disposal and emissions at site. Approximately $127 million of the total $602 million capital costs estimated in the May 2008 DFS Update will not be incurred in this revised plan.


Both the DFS Update and the 2011 Project Improvements are described in the October 2012 Technical Report.


Future Technical Report Updates


PolyMet intends to complete a full project update, incorporating the 2011 Project Improvements and final environmental engineering design controls as well as capital and operating costs, once detailed engineering design has been finalized. These environmental engineering designs include modular reverse osmosis (RO) water treatment facilities and other engineering controls that demonstrate NorthMet meets state and federal standards, including Minnesota's stringent water quality standards. PolyMet will incorporate these changes into a new Technical Report under 43-101, which it expects to publish in early 2013.
