133 Peru’s Emerging Copper Belt 3  Tintaya (120,000 tpy Cu in cathode and concentrates)  Antapaccay (1,470 mt 0.51% Cu)  Las Bambas (1,550 mt 0.61% Cu)  Haquira ( % Cu M&I plus % Inf.)  Constancia (480 mt 0.33% Cu, 0.04 g/t Au, plus Mo)

144 Company Profile  TSXV-listed mineral exploration company  Active solely in Peru since 2003  Three key projects:  Alicia (copper-gold), 55% interest with option to earn 100%, 5,000-metre drill program planned  Letra Rumi South (copper-silver), 100% owned, drill targets selected  Culebrilla (gold-silver), 100% owned 4

166 Strategy  Early stage exploration  Highest potential reward  Focus on Peru  Favourable geology, economy, mining culture  Develop pipeline of projects, adding value through exploration  Alicia Project top priority in

177 Project Locations  Alicia Project  Cusco Region  500 km SE of Lima  Letra Rumi South and Culebrilla  Ancash Region  250 km N of Lima 7

188 Peru’s Emerging Copper Belt 8  Tintaya (120,000 tpy Cu in cathode and concentrates)  Antapaccay (1,470 mt 0.51% Cu)  Las Bambas (1,550 mt 0.61% Cu)  Haquira ( % Cu M&I plus % Inf.)  Constancia (480 mt 0.33% Cu, 0.04 g/t Au, plus Mo)

199 Alicia Project  Community agreement in place  Environmental, sociological, archaeological baseline studies completed  Category 2 drill permit pending  Geophysical surveys completed – ground IP; airborne mag, radiometric and ZTEM  Detailed mapping and sampling ongoing  Drilling – 15-hole, 2,000-metre reconnaissance campaign completed; 5,000-metres planned 9

sq-km Concession 11 Area of Interest Good Access View of access road. Photo taken from Alicia property.  65 km south of city of Cusco  Existing road to the property Property boundary

112 Two key thresholds 12  Is the system mineralized? Drilling confirms robust values  Is there potential for size? Mapping and rock sampling identified an 800m long north-west south-east trending mineralized zone in porphyry Soil sampling to the west and northwest of this zone identified a copper anomaly defined by >500ppm Cu over 1,400 x 640 metres

113 Alicia Area of Interest, drilling drilling

114 Drill highlights, northern contact

115 Alicia Project, Drill Results 15  Hole ALC m (20.4m, TW) % Cu, 0.14 g/t Au  Hole ALC m (21.2m TW) % Cu, 0.13 g/t Au - ended in mineralization - bottom 5.1m returned 2.17% Cu, 0.21 g/t Au

116 Alicia Project, Drill Results 16  Hole ALC m (94.3m TW) % Cu, 0.04 g/t Au  Includes 50.5m (37.2m 0.64 Cu, 0.08 g/t Au

117 Alicia Project, Drill Results 17  Hole ALC Cu, 0.02 g/t Au - includes 1.20% Cu, 0.15 g/t Au  First hole drilled by Strait into the intrusive, indicates potential of the porphyry.

118 Plans for Alicia  5,000-metre drill program – Test geophysical anomaly on northern contact at depth – Test porphyry potential based on results of airborne geophysics  Mapping, sampling on balance of property 18

119 Other projects: Letra Rumi South and Culebrilla  Both projects ~250 km north of Lima:  Letra Rumi South (copper-silver)  Culebrilla (gold)  100%-owned by Strait Gold  Nominal holding costs  Letra Rumi South – ready to drill  Culebrilla – good surface showings, largely unexplored, followup required 19
