GOLDEN MINERALS ANNOUNCES PRELIMINARY ECONOMIC ASSESSMENT FOR
SANTA MARIA PROJECT
Golden, Colorado ‐ /PRNewswire/– February 15, 2017 – Golden Minerals Company (NYSE MKT: AUMN;
TSX: AUM) (“Golden Minerals”, “Golden” or “the Company”) is pleased to announce positive results
of a Preliminary Economic Assessment (“PEA”) for its Santa Maria silver and gold project located
near Santa Barbara in Chihuahua State, Mexico.
The PEA presents a base case assessment of developing Santa Maria’s mineral resource and
incorporates the results of an updated National Instrument 43‐101 (“NI 43‐101”) compliant
mineral resource estimate dated as of February 15, 2017.
PEA Highlights
Post ‐tax net present value (“NPV”) of $6.4 million and pre ‐tax internal rate of return of
84 percent at an 8 percent discount rate
Total capital requirements of $1.2 million (initial capital $1.0 million, sustaining capital
$0.2 million)
Pre ‐production development time 10 to 11 months
Life of mine (“LOM”) 3.2 years
Payback in month 16
LOM free cash flow $8.5 million
LOM silver production 2.1 Moz; LOM gold production 7.2 koz
LOM average silver grade 332 grams per tonne (“gpt”); average gold grade 1.28 gpt
LOM cash cost of $12 per Ag oz (net of Au credits)
Note: PEA parameters assume prices of $1,222/oz gold, $17.30/oz silver and a discount rate
of eight percent. Values above are approximate. All $ values in $US.
Warren Rehn, President and Chief Executive Officer of Golden Minerals, commented, “We are pleased
with the results of this independently‐prepared PEA, as it presents a low cost and profitable operation at
current metals prices. If we go ahead with the project, production at Santa Maria would mark Golden’s
re‐emergence as a producer of close to one million silver equivalent ounces annually, with the potential
to move the company to positive net cash flow. We believe there is also excellent potential for expansion
of the project which could lead to continued production beyond the initial three‐year period considered
in the PEA.”

Next Steps
Golden will continue work related to optimizing operating plans for the project and obtaining permits for
the potential mining operation as considered in the current PEA. Permit applications have been submitted
and are pending comment and acceptance. Golden is also developing plans for additional exploration
work to expand the resource.
Mining Operations
The PEA contemplates a 38‐month underground mining operation initially utilizing pre‐existing
underground development at a mine production rate of 200 tons per day using a combination of cut and
fill, shrinkage and other mining techniques, and custom milling at a local third‐party flotation mill. As
Golden Minerals already owns the mining equipment required to complete this project, the out of pocket
capital costs for start‐up are expected to be low.
Key parameters of the PEA are as follows.

Santa Maria Mineral Resource Estimate Dated February 15, 2017
In conjunction with the PEA, the independent firm of Tetra Tech prepared an updated NI 43‐101
compliant mineral resource estimate. The new estimate incorporates results of 24 additional
underground drill holes and 460 channel samples from drifts and the trial mining face. The
underground drilling and channel sampling have allowed for a more than doubling of indicated
resources since the previous April 2015 mineral resource estimate.
Indicated and Inferred mineral resource estimates as of February 15, 2017 for Santa Maria are shown as
follows:
Initial Sustaining Total
Capital ($M) Capital ($M) Capital ($M)
Mining $0.4 $0.0 $0.4

Property Title and Ownership
Golden has the right to acquire the Santa Maria property under an option agreement that requires
approximately $0.9 million more in payments in order to acquire 100 percent of the property.
Minimum payments of $0.1 million are due every April and October, and Golden has already
advanced the minimum payments for 2017 to the property owner. In addition, until Golden has
paid the remaining $0.9 million due under the option agreement, the property owners have the
right to 50 percent of any net profits from mining activities at the property, after reimbursement
of all costs incurred by Golden since April 2015, to the extent that such net profit payments exceed
the minimum payments.

Instrument 43‐101 of the Canadian Securities Administrators. Tetra Tech is an independent engineering
firm that served as principal author of the PEA prepared on behalf of the Company. Geoff Elson, PG is the
independent Qualified Person from Tetra Tech who reviewed and approved the portions of this press
release regarding mineral resources. Mark Horan, P.Eng of Tetra Tech is the independent Qualified Person

The PEA is preliminary in nature and includes Inferred mineral resources that are considered too
speculative geologically to have the economic considerations applied to them that would enable them to
be categorized as mineral reserves. Standalone economics have not been undertaken for the indicated
resources and as such no reserves have been estimated for the Project. There is no certainty that the
economic results described in the PEA will be realized. Mineral resources that are not mineral reserves do
not have demonstrated economic viability.

Cautionary Note to U.S. Investors concerning Estimates of Mineral Resources
This press release uses the terms “mineral resources”, “indicated mineral resources” and “inferred
mineral resources” which are defined in, and required to be disclosed by NI 43‐101. We advise U.S.
investors that these terms are not recognized by the SEC. The estimation of measured resources and
indicated resources involves greater uncertainty as to their existence and economic feasibility than the
estimation of proven and probable reserves. Mineral resources are not mineral reserves, and U.S.
investors are cautioned not to assume that mineral resources will be converted into reserves. The
estimation of inferred resources involves far greater uncertainty as to their existence and economic
viability than the estimation of other categories of resources. U.S. investors are cautioned not to assume
that estimates of inferred mineral resources exist, are economically mineable, or will be upgraded into
measured or indicated mineral resources.
Cautionary Statement regarding Mineralized Material
“Mineralized material” as used in this press release, although permissible under the SEC’s Industry Guide
7, does not indicate “reserves” by SEC standards. We cannot be certain that any deposits at the Santa
Maria project will ever be confirmed or converted into SEC Industry Guide 7 compliant “reserves”.
Investors are cautioned not to assume that all or any part of the disclosed mineralized material estimates
will ever be confirmed or converted into reserves or that mineralized material can be economically or
legally extracted.
Forward‐Looking Statements
This press release contains forward‐looking statements within the meaning of Section 27A of the
Securities Act of 1933, as amended and Section 21E of the Securities Exchange Act of 1934, as amended,

and applicable Canadian securities legislation, including statements regarding the Santa Maria PEA results
(including cost estimates, development timing, expected cash flow and life of mine and production
expectations), estimates of mineral resources for the Santa Maria project, and other expectations
regarding the Santa Maria project, including operating and exploration plans, cost expectations and title
and ownership matters. These statements are subject to risks and uncertainties, including: the
reasonability of the economic assumptions at the basis of the PEA, changes in interpretations of
geological, geostatistical, metallurgical, mining or processing information and interpretations of the
information resulting from future exploration, analysis or mining and processing experience; new
information from drilling programs or other exploration or analysis; unexpected variations in mineral
grades, types and metallurgy; fluctuations in silver and gold metal prices; failure of mined material or
veins mined to meet expectations; increases in costs and declines in general economic conditions; and
changes in political conditions, in tax, royalty, environmental and other laws in Mexico, and financial
market conditions. Golden Minerals assumes no obligation to update this information. Additional risks
relating to Golden Minerals may be found in the periodic and current reports filed with the SEC by Golden
Minerals, including the Company’s Annual Report on Form 10‐K for the year ended December 31, 2015.
