Project History

• Concession hosts the historic open-pit Santa Rita copper-gold-silver deposit

– Historic production of 245 million lbs Cu, 160,000 oz Au and 2.61 million oz Ag1

– Reported mill recoveries of 60 – 80%

• Early mining focused on high grade ore (5.37 million tonnes of ore mined grading 2.06% Cu, 0.93 g/t Au and 15.08 g/t Ag) with 2% copper stockpiled in early days1

• First gold recovery during the last five years of production

• Mine closed in 1975 due to low copper prices

• Management believes that a substantial amount of Cu-Au-Ag mineralization lies both below and adjacent to the Santa Rita pit

Notes on Mineral Resource Estimation1. The mineral resource estimate base case is reported at a 0.15% copper equivalent cut-off grade; this cut-off incorporates consideration of mining and processing cost,

recoveries, commodity prices and selling cost.2. The mineral resource estimate is reported on an undiluted basis.3. The mineral resource estimate assumes a long term copper price of US$2.90/lb, a gold price of US$1,200/oz and a silver price of US$24/oz.4. Rounding as required by NI 43-101 reporting guidelines may result in apparent summation differences between tonnes, grade and contained metal content.5. Tonnage and grade measurements are in metric units. Contained gold and silver ounces are reported as troy ounces, contained copper pounds as imperial pounds.6. Mineral resources that are not mineral reserves do not have demonstrated economic viability. The estimate of mineral resources may be materially affected by

environmental, permitting, legal, title, taxation, sociopolitical, marketing, or other relevant issues.7. The quantity and grade of reported inferred mineral resources in this estimation are uncertain in nature and there has been insufficient exploration to define these inferred

mineral resources as indicated or measured mineral resources and it is uncertain if further exploration will result in upgrading them to indicated or measured mineral resources.

Santa Rita and R-13 Deposits

• 18 diamond drill holes totaling 5,500 m completed

• Wide intercept of 65 m grading 1.48 g/t Au including 8 m grading 6.9 g/t Au and 15 m grading 0.57% Cu, 1.52 g/t Au and 5.93 g/t Ag in hole D9101

• Hole D914 intercepted 8 m grading 29.54 g/t Au from 240 m, including 2 m grading 110.68 g/t Au2

– Visible gold noted locally in the drill core

– Results demonstrate the presence of bonanza grade gold values along a northwest-trending gold-bearing corridor

• Hole D915 returned 10 m grading 1.42% Cu, 0.18 g/t Au and 20.45 g/t Ag3 within a wider intercept approximately 120 m below the base of the Rosita pit

• Drill program has been successful in identifying skarn-hosted Cu-Au-Ag mineralization along a 1.1 km long and 200 m deep corridor below and adjacent to the Santa Rita pit

Potential to add additional tonnage to an already robust stockpile resource
