Growth for New Opportunities

new truck delivery to GMC

More than 95% of GMC collections are in-kind donations from energy and mining companies, government agencies, universities, native corporations, and engineering firms.

The GMC collections volume has steadily increased since 1984 and expanded more than 50% over the last three years. Our 90,000 square-foot repository houses more than 680,000 detailed samples. See the most recent additions to the collections.

Continuing Donations

The GMC depends on new donations to ensure a robust collection of Alaska samples. Many times, companies may face discarding or abandoning samples to minimize storage costs, but donating to the GMC is a great alternative.

The GMC Curator, in collaboration with affiliated geologists, will review all donations pending determination of geologic significance and human safety.
