Spectrum Resources Incorporated (SRI) is a mineral exploration company based in Fairbanks, Alaska, whose goal is to provide quality, professional exploration services to the mineral industry in Alaska and beyond. We have been exploring Alaska since 1977.  We have completed numerous projects in almost every corner of the state, and have been involved with numerous discoveries. Our success is a direct result of our diligent ‘boots-on-the-ground’ approach and our belief that nothing replaces good solid field work.
