Drill Program Results Continue To Deliver For Project Advancement

ANCHORAGE, AK - Donlin Gold LLC reported on initial assay results for 18 completed drill holes, plus additional partial results for 11 holes from the 2021 drill program. The assay results have been received from approximately 7,500 meters of drilling. Significant new high-grade drill hole intercepts in ACMA and in areas between ACMA and Lewis deposits (Divide) point toward the potential feeder zones of this large system. Collected data supports the mineral resources, provides further information on local variability, and further increases confidence in recent geologic modeling concepts. The drill program, expanded by approximately 15 holes and 4,000 meters from the original 2021 plan, should provide important information on mineralization continuity that will support feasibility work.

The primary objective of the 2021 drill program is to complete the work necessary to validate and increase the confidence in recent geologic modeling concepts. Initial results indicate variable controls on mineralization in different deposit areas, with more continuous mineralization hosted in ACMA intrusives and more discrete intervals occurring in the sediments and intrusives in Lewis. The additional confirmation and extension drilling focuses on further testing of orebody continuity and structural control, and data collection for geotechnical and geometallurgical analysis. The drilling program was recently expanded to test an area of ACMA for mineralization continuity. The 2021 drill program is expected to encompass approximately 80 holes for a total of 24,000 meters drilled and should wrap-up in the fall. The logging and assay results will then be incorporated into a geologic model update, followed by a shift in focus to feasibility study work, subject to a formal decision by the Donlin Gold Board.
