Orosur Mining Intercepts High Grade Gold, including 5.32m at 17.76g/t Au, in Colombia
Montevideo, Uruguay, November 14, 2017. Orosur Mining Inc. (“Orosur” or “the Company” ) (TSX /AIM:
OMI), a South America-focused gold producer, developer and explorer, is pleased to provide a preliminary
update from its current drilling programme at its APTA target in the Company’s wholly -owned high-grade
Anzá gold project located in the Mid Cauca Gold Belt in Colombia.
HIGHLIGHTS FROM MAP-54
• 5.47 g/t Au over 4.63m from 97.1m to 101.73m, including 771.3 ppm Cu and 1.44% Zn
• 1.68 g/t Au over 1.0m from 126.0m to 127.0m, including 193.2 ppm Cu and 1.22% Zn
• 17.76 g/t Au over 5.32m from 144.50m to 149.82m, including 4,724.7ppm Cu and 4.84 Zn
• 1.84 g/t Au over 9.28m from 149.82m to 159.1m, including 2,398.0 ppm Cu and 2.26% Zn
Since mid -October, Orosur has drilled 3 holes ( 962.5m) of its planned 15,000m diamond drilling
programme. Partial sampling, representing just 30% of the samples to be analyzed from the first 2 holes
(MAP 54 & MAP 55), was sent to SGS Laboratory in Medellin for assaying. Assay results include a number
of high grade gold intersect intervals as well as copper, zinc and other notable byproducts as summarized
in the table below:

The limited assays returned to date from Hole MAP-55 show interesting gold anomalies up to 0.26 g/t Au,
which matches up with the gold bearing units identified in the area.

Ignacio Salazar, CEO of Orosur, said:
“These initial results are extremely encouraging , supporting the presence of high gold mineralization over
significant intervals and increasing confidence in the mineral body beyond the 17,000m of previous drilling
prior to the acquisition of the project by OMI.
“These results are merely the beginning of Orosur’s first drilling campaign at APTA. APTA mineralization
remains open at depth and along strike.”
Quality Control and Reporting Protocols
This initial drill program recovered HQ core which was logged, split in half for sampling, with the remainder
stored for reference in the secure core facility at Finca El Vergel, Anzá, Antioquia, Colombia. Samples are
delivered to SGS lab, Medellín, Antioq uia, Colombia (ISO/IEC 17025) for analysis. At the Laboratory,
samples are analyzed for gold by traditional fire assay with atomic absorption finish, with those samples
returning >5 g/t gold repeated using a 30g aliquot and gravimetric finish. All samples are also analyzed for
multi-elements including silver, lead, copper and zinc by total digestion ICP.
Drill program design, Quality Assurance/Quality Control (“QA/QC”) and interpretation of results is
performed by qualified persons employing a QA/QC progra m consistent with NI 43 -101 and industry best
practices. Standards, duplicates, and blanks are added at the lab as well as standards, duplicates, and
blanks submitted as unknowns by the Company every 10 samples.
Assays are reported as composited intervals using weight averages, with highly enriched zones reported
separately. Assays are uncut at this time. Applicable true widths are determined by ongoing investigation
of the continuity and geometry of zones, and are typically expected to be 65% to 85% of th e reported
core lengths.
