TSXV: NCX 12

Project History

• 1967: Utah discovers Island Copper deposit

• 1968 to 1988: Utah acquires large package in area and discovers Hushamu deposit

• 1988: Moraga options properties from BHP / Utah

• 1988 to 2002:Moraga and Jordex carry out drilling and engineering studies of Hushamu

• 2002: Lumina buys Moraga from Jordex

• 2006: Lumina sells Moraga to Western Copper as part of larger asset purchase

– Hushamu property valued at approximately $ 12million.

• 2006- 2007: Western explores the NW Expo area, little work on Hushamu

• 2008 to 2009: IMA options property: further explores NW Expo area

• 2011: Western creates new company “Northisle” to explore and move project forward

Newly Identified IP Chargeability Anomalies

IP anomaly extends for 2km north west of deposit – untested by drilling

Two additional IP anomalies located in NW Expo area – one area un tested by drilling

Anomalies May Indicate Additional Areas of Porphyry Copper Mineralization

TSXV: NCX 16

Additional Targets

- NW Expo Area - Mo and Au mineralization demonstrated in drill holes over 600 metres strike - Two new IP chargeability anomalies may indicate new areas of porphyry

copper mineralization.

- Hep Showing - Copper soil anomaly not fully evaluated

- South MacIntosh - Broad area of alteration partially drill tested

- Pemberton Hills - High level alteration may indicate porphyry deposit at depth

- Rupert - Magnetic anomaly and two untested IP chargeability anomalies.

TSXV: NCX 17

2012 - 2013 Exploration Programs

- Complete an IP Survey over untested areas (Completed)

- Determine Rhenium and Molybdenum content of Hushamu by

resampling the core (Completed)

- Define limits of Hushamu deposit by drilling (Drilling Completed)

- Begin background environmental baseline studies (Started Sept 2011)

- Update the Hushamu resource calculation with 2012 drilling

(Completed)

- Preliminary Engineering studies (Underway)

TSXV: NCX 18

Business Plan

Increase company value through measured and systematic de-risking of the deposit Short term (next 4 months)

- Complete PEA

Mid term (Q2 2013 to 2014)

- Move Inferred Mineralization to Indicated and Measured

- Begin Pre feasibility Study

- Market project to potential buyers / partners

Long term (2014 to 2015)
