The Kwanika claim group is 11,194 hectares in size and is held entirely by Kwanika Copper Corporation (KCC).
Kwanika is located in the northern Quesnel Trough, which hosts numerous porphyry copper-gold deposits and are accessible by road from the city of Fort St. James, British Columbia.
An advanced stage copper-gold project located near infrastructure in a politically stable jurisdiction. Kwanika's resource estimate includes a high-grade, well defined domain within the Central Zone on the property, which is currently undergoing a Pre-Feasibility Study fully-funded by strategic partner POSCO DAEWOO Corp. with scheduled completion Q2/2019.
Kwanika Copper Corporation is jointly held by Serengeti Resources Inc. (SIR; 65%) and POSCO DAEWOO Corporation (PDC; 35%).
Pre-Feasibility Study – Currently Ongoing
Kwanika is currently undergoing a Pre-Feasibility Study (“PFS”) fully funded by partner POSCO DAEWOO Corp. which will culminate in the publishing of an independent NI 43-101 compliant Technical Report, scheduled for Q2/2019. The study is being managed by an industry-leading consortium of engineering consultants including Merit Consultants International, Cementation USA, Klohn Crippen Berger and Tetra-Tech.
The PFS is investigating a new strategic mine plan in order to improve upon economics presented in the 2017 PEA. Notable areas of interest include exploring alternative mining options, staged development capital and focusing on higher-grades/margins. KCC completed a 7,400-metre drilling program in September 2018 which focussed on possible resource upgrade and expansion and investigation of high-grade zones, as well as detailed geotechnical data acquisition and hydrogeological testing to enable detailed engineering design.

An independent NI 43-101 Preliminary Economic Assessment (“PEA”) for the Kwanika copper-gold porphyry project located in the Quesnel Trough of North-Central British Columbia, Canada was completed in April 2017. The results of the PEA demonstrated the potential technical and economic viability of establishing a new copper-gold mine and mill complex on the property. The independent PEA was prepared by Moose Mountain Technical Services (see NR 2017-04, April 3rd, 2017 for full details).
Pre-tax NPV7% of CDN $324 million, 21.1% IRR, 15 year mine life.
Life of mine (LOM) metal production of 601 million pounds copper, 676,300 ounces gold, and 2.66 million ounces silver in concentrates.
Annual metal production of 50.4 million pounds of copper, 70,100 ounces of gold, and 181,100 ounces of silver in concentrates for the first eight years.
Initial capital cost of CDN $476 million plus LOM sustaining capital and closure cost of $83 million for a 15,000 tpd (5.4 million tpa) mill and combined open pit, underground mining operation.
Projected C1 (Direct cash cost of productionper pound of copper net of gold, silver credits) of US$0.70/lb/Cu for first eight years or US$1.20/lb LOM
2016 Kwanika Mineral Resources Estimate
The independent resource estimate was completed by SRK Consulting (Canada) Inc., of Vancouver British Columbia. (see NR16-13, November 14, 2016 for full details)

* Pit constrained mineral resources are reported in relation to a conceptual Whittle pit shell and underground resources are reported within the area for potential underground development. Mineral resources are not mineral reserves and do not have demonstrated economic viability. All figures are rounded to reflect the relative accuracy of the estimate. All composites have been capped where appropriate.
** Pit constrained mineral resources are reported at a copper equivalent cut-off of 0.13% and underground resources are reported at 0.27%. The cut-offs are based on prices of US$3.00 per lb of copper, US$1,300 per ounce of gold, US$20 per ounce of silver, US$9.00 per lb of molybdenum and assumed recoveries of 89% for copper, 70% for gold, 75% for silver, and 60% for molybdenum.
Plans moving forward
Following receipt of results from the 2018 drilling program an updated Mineral Resource Estimate will be produced which, along with results of metallurgical testing, will enable detailed engineering design work for the PFS. An independent NI 43-101 compliant Technical Report will be published Q2/2019.
Location and Infrastructure
Kwanika represents an advanced stage copper-gold project located near infrastructure in a politically stable jurisdiction. Kwanika is located in the northern Quesnel Trough, which hosts numerous porphyry copper-gold deposits. The Kwanika claims are 11,194 hectares in size and accessible by road from the city of Fort St. James, British Columbia.
A landmark access agreement was signed in August 2010 with the Takla Lake First Nation, and renewed in May 2018, which has facilitated First Nations' support for the project through the completion of the PFS.
David Moore and Myron Osatenko in 2010 H.H. "Spud" Huestis Awards
Copper mineralization was first recognized along Kwanika Creek in 1964.
Since 2006, Serengeti has drilled 82,650 meters at the Kwanika project. In 2010, Serengeti principals David Moore, President and CEO, and Myron Osatenko, former Chief Geologist, were awarded the Association of Mineral Exploration, British Columbia (AMEBC) H.H. "Spud" Huestis Award for Excellence in Prospecting and Mineral Exploration in recognition for their discovery of the Kwanika deposit.
The property is situated in the northern Quesnel Trough, which hosts numerous porphyry copper-gold deposits. The regional geology consists of Jurassic age andesitic volcanic rocks intruded by monzodiorites and monzonites with the Pinchi and Manson Creek faults on the west and east sides respectively. Kwanika is located between Northgate's former Kemess Mine, and the Mt. Milligan deposit, reported to contain mineable reserves of 6.0 million ounces of gold and 2.1 billion pounds of copper, currently being developed by Thompson Creek Metals.
The Kwanika project consists of two porphyry deposits, the Central copper-gold Zone and the South Zone, a copper-molybdenum-gold-silver zone located two kilometers to the South.
The Central Zone (copper-gold) deposit is characterized by the presence of two major and several minor intrusive bodies of the multi-phase Hogem Batholith intruding a succession of andesitic rocks of the Takla Volcanic Group. Hypogene mineralization consists of disseminated chalcopyrite, bornite, and pyrite in and around a potassically altered monzonite stock. Where strongly mineralized, the unit commonly displays quartz stock work and hydrothermal brecciation. The highest grades occur within zones of strong to intense, texture destructive albite-hematite alteration, commonly occurring at the top of the hypogene mineralized zone. A supergene enrichment blanket has been superimposed on the Central Zone and extends to depth beneath unconformably overlying post-mineral sedimentary rocks which have preserved the supergene zone. Thickness of the supergene profile ranges from 5 to 70 meters in thickness and extends laterally for up to 500 meters. Two distinct assemblages of supergene mineralization are observed in the Central Zone; minor, supergene oxide (native copper) and prevalent, supergene sulphide (chalcocite, covellite).
The South Zone (copper-molybdenum-gold-silver) deposit occurs within a fault bounded sequence of strongly altered intrusive rocks of alkalic to intermediate composition. This structural corridor is bounded by the 'West Fault' to the west and possibly by a similar fault interpreted to lie along the east boundary of the corridor. Coincident chargeability and resistivity anomalies form a geophysical domain that represents the fault bounded South Zone corridor. This variably mineralized domain is 2,900 meters long and up to 500 meters wide.
