Disclaimer

This Presentation contains certain "forward-looking statements" including, without limitation, expectations, beliefs, plans and objectives regarding the timing and nature of estimated future exploration, success of exploration activities, and potential transactions and ventures discussed. Among the important factors that could cause actual results to differ materially from those indicated by such forward-looking statements are the risks inherent in mineral exploration, the need to

  • btain additional financing, environmental permits, the availability of needed personnel and equipment for exploration and

development, fluctuations in the price of minerals, and general economic conditions. Wade A. Hodges, CEO of Nevada Exploration Inc., is the Qualified Person, as defined in National Instrument 43-101, and has prepared the technical and scientific information contained in this Presentation.

PHASE 1 DRILLING PROGRAM

South fence North fence Middle fence

Objectives of Phase 1 drill program:

  • 1. Widespread CTGD architecture

(favourable lower-plate + structures)

  • 2. Large CTGD footprint

(alteration + thick intervals of pathfinders) To test:

  • Three fences of DH locations, approx. 1 km

apart, with holes every 400 m

  • Plan to drill average of 2 holes per fence
  • Total approx. 4,500 metres (US$1.5M)

What’s next at South Grass Valley

  • 1. Update geologic model
  • Good spread of data from three fences
  • Regional stratigraphic section
  • Within section, what are best units
  • Within the best units, highest

pathfinders – provide vectors (E or W)

  • 2. Define the edges of the system
  • Additional wide step out drill holes
  • Identify best places for infill drilling

NEXT STEPS

Test north along strike (soil mercury + groundwater) Based on updated exploration model, vector towards source of mineralized fluids Objectives

  • 1. Establish where best host rocks intersect

best fluid pathways (mineralizing controls)

  • 2. Guide targeted Phase 3 in-fill drilling
