Andean Precious Metals Provides Update on San Bartolome Expansion Study
Andean Precious Metals Provides Update on
San Bartolome Expansion Study
Toronto, Ontario--(Newsfile Corp. - April 21, 2022) - Andean Precious Metals Corp. (TSXV: APM)
(OTCQB: ANPMF) ("
Andean
" or the "
Company
") today provided an update on the progress of the
Company's scoping level study (the "
Expansion Study
") at the San Bartolomé Mine in Bolivia.
The Expansion Study is evaluating options to extend the life of mine at San Bartolomé through the
extraction of silver and tin contained in a stockpile of fine material at the fines disposal facility ("
FDF
")
adjacent to the tailings facility. Information pertaining to the FDF was included in a National Instrument
43-101 Standards of Disclosure for Mineral Projects technical report dated March 25, 2022, titled "NI
43-101 Technical Report San Bartolomé Mine Bolivia". As disclosed in this technical report, the FDF
contains 16.2 million silver ounces and 11,930 tonnes of tin within 10.15 million tonnes of indicated
mineral resources and 2.3 million ounces of silver and 1,330 tonnes of tin within 1.51 million tonnes of
inferred mineral resources. The Expansion Study will inform the Company's decision to move forward
with a feasibility study related to the FDF.
Golder Associates Inc. have completed preliminary engineering work on hydraulic mining and SGS
Canada Inc. are currently undertaking metallurgical test-work on the first batch of 23 samples recovered
in the resource definition drill program. This will be followed by similar testing on composite samples
from the remaining 59 drill holes currently in storage at the laboratory. Initial testing suggests that tin and
silver-bearing ore can be pre-concentrated by discarding very fine material ahead of a recovery circuit.
Heavy liquid test-work and mineralogy is in progress and will guide the gravity concentration flowsheet
design.
Progress Update
Initial capital estimates for the hydraulic mining and tin recovery circuit are lower than expected,
ranging from US$20M to US$25M versus previous guidance of US$30M to US$50M;
Estimated hydraulic mining costs range from US$0.80 to $0.95 per tonne;
Estimated operating costs for gravity tin recovery range from US$4.50 to US$5.50 per tonne
based on the initial flowsheet, exclusive of silver processing costs of approximately US$18 per
tonne;
Silver recoveries are expected to be consistent with current process plant performance subject to
continued test-work confirmation;
Initial analysis supports the utilization of pre-concentration to upgrade the metal content of material
being delivered to the proposed gravity and existing leach circuit.
The Company has experienced significant delays on the metallurgical test program due to
transportation, customs and Covid-19 impacts, along with backlogs at SGS Canada's testing facility in
Lakefield. These delays may impact the Company's ability to complete the Expansion Study by the end
of the second quarter as previously guided.
"Initial estimates for capital costs, operating costs and silver recoveries are positive, and we continue to
advance our understanding of tin processing options while managing test-work delays," said Simon
Griffiths, President and CEO. "While initial results support our thesis on pre-concentration and gravity
recovery of tin, we need to work through our backlog of metallurgical testing before we make a decision
to move forward with the next phase." Mr. Griffiths went on to say, "we continue to believe that the
materials in the FDF represents substantial value for Andean stakeholders - which we will develop in a
methodical fashion, ensuring that a decision to invest shareholder capital is fully supported by the data. I
am confident that we will work through the current delays and look forward to updating the market on our
progress before the end of this quarter."
Additional Information - Dry Stack Tailings
As previously disclosed, the Company has also undertaken a drill program at the dry-stack tailings
facility ("
DSF
") with the objective of defining both silver and tin mineral resources. This drill program is
now complete, with roughly one-half of assays received. The Company expects to release these results
in full once the remainder of the assays have been received. The DSF contains an estimated 20 million
tonnes of material, from which silver, but not tin, have been recovered since production began in 2008.
The Company expects to undertake a similar evaluation of processing options for both silver and tin in
the DSF once the complete data-set is available.

statements are often identified by the words "may", "would", "could", "should", "will", "intend", "plan",
"anticipate", "believe", "estimate", "expect" or similar expressions. Forward-looking statements in this
news release include statements relating to Andean's decision to move forward with a feasibility study
related to the FDF and the basis therefor, the work to be completed with respect to the preliminary
engineering study and metallurgical test-work, the estimates relating to the capital estimates for the
hydraulic mining and tin recovery circuit, hydraulic mining costs and operating costs for gravity tin
recovery, expected silver recoveries, the utilization of pre-concentration of material being delivered to the
proposed gravity and existing leach circuit and the timing of an initial resource estimate.
Investors are cautioned that forward-looking statements are not based on historical facts but instead
reflect Andean's expectations, estimates or projections concerning future results or events based on the
opinions, assumptions and estimates of management considered reasonable at the date the statements
are made. Although Andean believes that the expectations reflected in such forward-looking statements
are reasonable, such statements involve risks and uncertainties, and undue reliance should not be
placed thereon, as unknown or unpredictable factors could have material adverse effects on future
results, performance or achievements of Andean. Among the key factors that could cause actual results
to differ materially from those projected in the forward-looking statements are the following: changes in
commodity and power prices; risks inherent in exploration estimates; results, timing and success;
inaccurate metallurgical assumptions (including with respect to the grade and recoverability of mineral
resources); changes in development or mining plans due to changes in logistical, technical or other
factors; unanticipated operational difficulties (including failure of plant, equipment or processes to
operate in accordance with specifications, cost escalation, unavailability of materials, equipment and
third party contractors, delays in the receipt of government approvals, industrial disturbances or other job
action, and unanticipated events related to health, safety, and environmental matters); changes in
general economic, business and political conditions, including changes in the financial markets; changes
in applicable laws and regulations both locally and in foreign jurisdictions; compliance with extensive
government regulation; the risks and uncertainties associated with foreign markets. These forward-

Should one or more of these risks or uncertainties materialize, or should assumptions underlying the
forward-looking statements prove incorrect, actual results may vary materially from those described
herein as intended, planned, anticipated, believed, estimated or expected. Although Andean has
attempted to identify important risks, uncertainties and factors which could cause actual results to differ
materially, there may be others that cause results not to be as anticipated, estimated or intended and
such changes could be material. Andean does not intend, and does not assume any obligation, to
update the forward-looking statements except as otherwise required by applicable law.
