Highlights:

  • Intercepts from the Fortune Zone definition drill program confirming the internal continuity of gold mineralization
  • Multiple high-grade intercepts reported at the Fortune Zone including:
  • FOR-14-01 – 54.96 grams/tonne gold ("g/t Au") over 0.6m
  • FOR-14-09A – 20.73 g/t Au over 1.0m
  • FOR-14-12 – 14.53 g/t Au over 2.0m
  • FOR-14-15 – 19.07 g/t Au over 2.7m
  • FOR-14-16 – 24.11 g/t Au over 2.5m
  • Significant gold bearing intercepts reported at No. 5 Plug; drill spacing reduced to increase confidence in geological model to permit initial resource estimation
  • No. 5 Plug drilling returned multiple narrow but high-grade intercepts including:
  • P5-14-02 – 64.08 g/t Au over 0.5m
  • P5-14-06 – 22.41 g/t Au over 1.0m
  • P5-14-08 – 33.20 g/t Au over 0.8m
  • P5-14-16 – 17.87 g/t Au over 1.5m and 29.93 g/t Au over 1.0m

"The drill results announced at the Fortune Zone continue to improve our confidence in the Company’s geological model, while the drill results from the exploration program at No. 5 Plug demonstrate the ability for Integra to further grow the resource base and continue to discover new deposits on the property," noted Company President and CEO Stephen de Jong. "The No. 5 Plug in particular is within a few hundred meters of the proposed underground infrastructure for the Parallel zone in our existing mine plan meaning any potential resources we are able to define should be relatively simple to access."

Fortune Zone Definition Drill Program

The Company completed 5,771 m of drilling in 22 drill holes as part of the 2014 summer/fall drill program at the Fortune Zone. This program focused on reducing drill spacing in the core of the Fortune deposit while partially testing for extensions of gold mineralization laterally. The Fortune Zone, one of four deposits presently under economic evaluation at the PEA stage on the Lamaque South Project, is located in the northern part of the Lamaque South project.

Summary of Fortune Definition Drilling Program

The Company completed the infill definition drill program for this deposit in the fall of 2014. Drilling focused on decreasing drill spacing to between 25 to 40 m centers while confirming the continuity of gold mineralization within the deposit. The mineralization encountered at Fortune appears to be constrained within two major east-west vertical shear zones approximately 75 m apart. These geological structures are reminiscent of the gold mineralization setting present at the historic Sigma Mine, which produced more than 4.5 million ounces of gold and was recently acquired by Integra. At the neighboring Sigma Mine, located 500 meters from Lamaque, major flat to northerly dipping mineralized veins are present and are often constrained by sub-vertical shear zones.

No. 5 Plug Exploration Drill Program

The Company completed 4,338 m of drilling in 17 drill holes as part of the 2014 fall drill program at the No. 5 Plug. The goal of this program was to evaluate the lateral continuity of reported intercepts from the 2012 program on that plug and reduce drill spacing to between 50 to 75 m centers for near surface zones, defined as 0 to 300 m vertical. The No. 5 Plug is located in the northern part of the Lamaque South project, only a few hundred meters south of the recently acquired Sigma Mill.
