Vancouver, B.C., February 06, 2013: Serengeti Resources Inc. (SIR: TSX-V; 34S: FSE) is pleased to announce the completion of an independent NI 43-101 compliant Preliminary Economic Assessment (“PEA”) for its 100% owned Kwanika copper-gold porphyry project located in the Quesnel Trough of North-Central British Columbia, Canada. The results of the PEA demonstrate the potential technical and economic viability of establishing a new copper-gold mine and mill complex on the property.
- Pre-tax NPV5% of CDN $263 million, 13.4% IRR, 13.5 year mine life.
- Life of mine (LOM) payable production of 545 million pounds copper, 489,000 ounces gold, 2.45 million ounces silver and 5.25 million pounds molybdenum.
- Initial capital cost of CDN $364 million plus LOM sustaining capital of $144 million for a 15,000 tpd (5.5 million tpa) mill and combined open pit, underground mining operation.
“Serengeti is very pleased to have achieved this important milestone for the Kwanika project.” commented David W. Moore, President & CEO. “Kwanika represents an opportunity to develop a midsize greenfields copper-gold project in an excellent location and proven jurisdiction. The independent consultant has recommended selected optimization studies to refine certain engineering and costing elements, the results of which could be incorporated into an optimized PEA. We are currently funded to take this next step.”
The PEA prepared by Moose Mountain Technical Services (“MMTS”) is based on the resource model presented in the March 3, 2011 NI43-101 technical report titled “Technical Report on the Kwanika Project, Fort St. James British Columbia, Canada”, authored by David W. Rennie of RPA Inc formerly Roscoe Postle Associates Inc. RPA’s Technical Report used a large scale confining pit shell to define contiguous mineralization. The resource therein at US $7.50 and $20.00 / tonne cut-off grades is shown in the following table:
|Zone||Open Pit Resource Category||Tonnes and Grade||Total Contained Metal|
|At Cut-Off of $7.50/tonne|
|Includes at Cut-Off of $20.00/tonne|
1. CIM definitions were followed for Mineral Resources; 2. Mineral Resources are estimated at a cut-off grade of US$7.50/t. The dollar value cut-off was estimated using provisions for metallurgical recovery and off-site costs; 3. Mineral Resources are estimated using an average long-term price of US$1,200/oz Au, US$3.50/lb Cu, US$17.00/lb Mo and US$21.00/oz Ag; 4. A minimum mining width of 5 m was used; 5. Metallurgical recovery factors of 89% Cu, 70% Au, 60% Mo and 75% Ag were used to derive the dollar value cut-off.
The MMTS study focused on a higher grade core of the deposit and delineated pit designs on the Central and South zones as follows:
Note: NSR cut-off used is Cdn$11.90/tonne with a provision for mining loss of 5% and dilution of 2%
And an underground Delineated Resource on the Central zone as follows:
Note: Includes all material within the conceptual stope design with a provision for mining loss of 10% and dilution of 15%
The mine plan generates the following throughput over the project mine life.
|Mine Production /|
Total tonnes milled (Mt)
|Cu (%)||Au (g/t)||Ag (g/t)||Mo (%)|
*Note: Mo produced from South pit only.
All mineralized material classified as Indicated (65%) and Inferred (35%) Mineral Resources was considered in the mine plan. The PEA is preliminary in nature and it includes inferred mineral resources that are considered too speculative geologically to have the economic consideration applied to them that would enable them to be characterized as mineral reserves. Mineral resources that are not mineral reserves, do not have demonstrated economic viability and there is no certainty that the results of the PEA will be realized.
A Base Case economic evaluation was generated incorporating historical three-year-trailing averages for metal prices as at October 15, 2012 and a reasonable assumption for a US$/CDN$ exchange rate. Results are shown in the following table:
|NPV (at 5%)||CDN$ M||262.6|
|NPV (at 8%)||CDN$ M||143.3|
Project Development Plan
The proposed project is to develop a green-fields copper-gold-silver-molybdenum deposit with a combination of open pit and block cave underground mining for the Central Zone and open pit mining for the South Zone combined with conventional milling and flotation concentration methods. The production rate assumed was 15,000 tonnes per day with a forecast mine life of 13.5 years. Mineral concentrate would be trucked approximately 190 kilometers to a rail load-out facility in Fort St. James and power would be provided by connecting to the existing Kemess mine power line which is connected to the provincial grid. Forecast mine production statistics are summarized in the following table:
|Grade||%||Total Production||Annual Production|
|Copper (%)||0.377||89||(000s lbs)||544,892||40,512|
|Gold (g/t)||0.295||70||(000s oz)||489.0||36.4|
|Silver (g/t)||1.378||75||(000s oz)||2,448||182.0|
|Moly (%)||0.016*||60||(000s lbs)||5,251||390.0|
*Note: Mo produced from South pit only.
Assumed capital and operating costs for the operation are as follows (in CDN$):
- Initial capital of $363.6 million including open pit mining equipment and preproduction mining costs, underground equipment and initial development, processing plant, site infrastructure, access and power and a contingency of $58.5 million
- LOM sustaining capital cost of $143.9 million including open pit sustaining, underground equipment and mine development and reclamation
- Total weighted operating cost of $21.20 / tonne processed including: open pit mining $2.42 / tonne mined; LOM strip ratio of 3.5:1; underground block cave mining $7.50 / tonne; mill and tailings $10.87 / tonne; G&A $1.20 / tonne.
Opportunities to Enhance Value
Several opportunities exist to increase overall value of the project while simultaneously reducing total costs:
- Optimization of the current mining plan in the Central Zone to determine most economic recovery method.
- Additional economic underground resources are possible adjacent to the block cave stope outline used in this report.
- A large mineralized envelope exists adjacent to the resource used in the current mine plan and offers expansion potential after proposed operation achieves capital payback.
- Other properties in the local area may have the potential of using the Kwanika facilities on a commercial or joint venture basis.
- Consideration could be given to reducing capital costs through use of contract mining and / or equipment leasing.
