Golden Minerals Reports Final Drill Results From Santa Maria 2017-2018 Drill Campaign
Golden Minerals Reports Final Drill Results From Santa Maria 2017-2018 Drill
Campaign
GOLDEN, Colo., April 30, 2018 -- Golden Minerals Company (“Golden Minerals”, “Golden” or “the Company”) (NYSE
American:AUMN) (TSX:AUMN) has released final results from the 22-hole 4800-meter drilling program conducted at its Santa
Maria property located in Santa Barbara, Chihuahua State, Mexico since August 2017.
Golden Minerals began an expansion drilling program in August 2017 at its Santa Maria gold and silver property located west
of Parral in Chihuahua State, Mexico. The Company recently expanded the claim package adding 77 hectares and more than
doubling the strike distance coverage on the Santa Maria vein to about one kilometer total. The current drill program was
initiated by the Company with the goal of expanding the existing resource to improve the overall economics reported in the
Preliminary Economic Assessment (“PEA”) published in March 2017. The Company has received assays for all 22 holes
drilled.
The recent drilling encountered oxidized vein material to much greater depths in the eastern part of the Santa Maria vein
system than in the western part. The oxidized portion of the eastern vein system is preserved due to normal faulting and post-
mineral basalt cover. In addition to the previously known Santa Maria vein and the hanging wall vein, Santa Maria 2, a breccia
vein labelled NE breccia was encountered in some of the drill holes (see table of results). Metallurgical test-work on the oxide
material is yet to be completed.
The Company plans to update the resource model and the PEA based on the new drill results and the new metallurgical
studies once those are available.
Golden’s President and Chief Executive Officer, Warren M. Rehn, notes, “The weighted average of silver grades of the intervals
reported here is higher than the previously reported silver grade of the mineral resource at Santa Maria. We expect an
improvement in the overall mineral resource and of the economics of the project because of this. We will update the resource
and the PEA as expeditiously as possible.”

*Less than 40% of core recovered. Reported grade may not be representative of actual vein grade.
**Interval previously reported in Oct. 25, 2017 news release.
Note: Some drill hole intervals have been composited from multiple adjacent samples and in some cases, may contain up to 1
meter of core with less than 100 g/t Ag if the overall interval weighted average is greater than 100 g/t Ag. Individual assay
intervals will be reported on the Golden Minerals website. “Significant Interval” is defined as at least 0.2 meters true width of at
least 100 g/t Ag or Ag equivalent based on Au times 70 plus Ag.
