Description

Notice of IntentThis is a notice of intent to solicit from a single source for the US Geological Survey, Alaska Science Center.The US Geological Survey (USGS) intends to negotiate a purchase order with AERIE LLC 187Re/187Os analyses of sulfide minerals in mineralized rocks collected by geologists. AERIE LLC is the only known source that has the required capabilities that meets the government's minimum needs. Re-Os geochronology of sulfides is a sophisticated and specialized technique that very few labs globally are capable of conducting. There is only one technique for the analyses which requires solution chemistry followed by double spiking and analyses via negative TIMS. As a result, very few labs are capable of the analyses. Three previous contracts were awarded to AIRIE for ongoing project related work. A recently completed award for submitted samples has generated additional questions that need follow-up analyses to fully characterize the Re- Os analyses on sulfides from the Pogo mine and nearby occurrences in interior Alaska.Further, new sites have now been sampled that will broaden our ability to distribute internally consistent datasets across a broader part of Alaska. Samples analyzed during the last contract were variably successful due to the unknown Re and common Os concentrations. Components of these samples remain at the lab in various states of mineral separation, solution chemistry and analysis from the prior contract. These samples require additional work to fully characterize the ages, now that we have learned more about the chemistry and success from the previous contract. As a result, no other lab is capable of completing the analyses, and for internal consistence in the dataset, it is paramount that AIRE continue the analyses. Given the ongoing collaboration with the AIRIE lab, and the consistency sample, the location of samples, and ongoing sampling work by AIRIE, AIRIE is the only lab currently capable of completing the current...
