Orosur Mining Inc. - Colombia Anzá Gold Project Exploration Update
SANTIAGO, Chile, January 19, 2017. Orosur Mining Inc. (“Orosur” or “the Company”) (TSX/AIM: OMI), the
South American-focused gold producer, developer and explorer is pleased to announce an update of its
exploration activities at its wholly -owned, high grade Anzá gold project (“Anza”) located in the Mid Cauca
Belt in Colombia.
Completion of preliminary geological model
Orosur has completed a preliminary geological model for the Aragon-Pastorera Trend Area (“APTA”) of the
Anzá project, based predominantly on 17,408m of existing diamond core drilling data from 53 holes
previously drilled . 3,000m of this core has been re-logged, with special attention given to the lithology,
alteration suites, structural trends and grade distribution.
Based on this information, a geological estimate of an exploratory gold potential of a portion of the APTA
has been prepared with the assistance of Mine Development Associates (“MDA”) of Reno, Nevada. The
resulting potential ranges between 1.6 M - 2.3 M tonnes averaging between 3.2 - 3.7g/t Au. This estimate
is based on current drilling and is expected to grow as future exploration drilling is conducted.
The Company believes that the mineralized zones in the APTA continue, both at depth and at the surface,
to the north and south of the limited area which has been analysed to date and included in the preliminary
model. As such, there is the potential for a much larger resource base to be identified.
The APTA extends 2 km along st rike of the vein -like deposit; but only accounts for a small portion of the
total Anzá project, which covers approximately 105 km² in total.
Previous drilling of Anzá has shown consistent high grade gold intercepts over significant widths as well as
coincident zinc mineralization. Anzá is situated in a well -known geological setting in Colombia already
hosting a number of substantial gold proje cts. The Anzá project has existing mine and environmental
permitting, and its existing infrastructure, including camps, roads, power and water, are in good standing.
Next steps in Colombia
During 2017, the Company plans to undertake a 15,000m - 30,000m drilling campaign to:
Delineate maiden resources;
Further define and expand the potential mineralization for APTA;
Test mineralization in undrilled areas of the deposit where strong indications of economic gold
occurrences exist; and
Commence initial drilling of nearby untested and highly prospective targets.
Upon completion of this drilling campaign, the Company intends to prepare and publish a maiden N.I. 43 -
101 compliant resource report for the Anzá project.
The Company will update the market once the upcoming exploration programme has been designed and
validated and a drilling contractor has been engaged.

Ignacio Salazar, CEO of Orosur, said:
“Orosur acquired Anzá in July 2014, through its nil premium all share acquisition of Waymar Resources, at
a time when little to no value was being given to exploration projects. Our ambition at that time is now being
rewarded with the encouraging initial exploration potential estimate for the drilled area. We look forward to
finalizing plans for progressing the Anzá project with significant drilling activities during 2017.
“The Company believes that Anzá has significant upside and we expect the project to take a more
prominent standing in our suite of South American gold assets in the months to come.”
About Anzá
Anzá is located in the Western Cordillera, 50 km west of the city of Medellín, 50 km south, along the Cauca
lineament, of Continental Gold’s high grade Buriticá gold project (4.7 Moz measured and indicated (“M&I”)
resource, grading 11.4 g/t Au) and 70 km from Red Eagle’s San Ramón project (479Koz M&I resource,
grading 3.5 g/t Au) which is a vein like gold deposit in a shear zone with a similar mineralization style as
the APTA in a different geological environment.
As previously announced in October 2016, initial preliminary metallurgy and density test work were
completed utilising a combination of gravity concentration, flotation and cyanidation processing , with
average gold recoveries rangi ng from 95.9 – 96.1%. This is in line with the metallurgical recoveries of
development projects and producing mines in the region.
The site has environmental permits enabling both underground and open -pit mining operations. The Anzá
project includes two small underground gypsum mines, each of which also have environmental and mining
permits granted by the Colombian authorities. Historically, the gypsum mines have been operated by a
third-party contractor; Orosur is currently in the process of taking over operatorship. The gypsum permits
can be readily expanded, enabling Orosur the ability to fast -track permitting for future gold mining
operations.
Access to the project is via a paved road to the town of Anzá and a 17 km gravel road operable all year
round. The gypsum mine has been in operation at the site since 1991. It has excellent infrastructure, with
power grid, abundant water and mine facilities on site. The elevation ranges from 700 m to 2,000 m above
sea level.
The APTA deposit is up to 200 m wide and at least 2.5 km long , with soil geochem showing gold content
along the entire 7km Aragón fault. The deposit is open on strike, at surface and down-dip. Significant drill
hole intercepts include:

The Anzá land package, which is wholly owned by Orosur, includes multiple additional highly prospective
potential gold targets. In addition to the APTA, there is an extensive area of more than 100 km² open to
exploration. Charrascala and Guaimarala are two of the most highly promising additional gold targets. At
Charrascala, there are existing outcrops with gold and copper mineralization. Favourable topography,
existing infrastructure and the existence of a wide low-grade gold envelope in the Anzá land package
provide further exploration, development and mining upside, all with strong indications of the potential for
significant by-product mineralization.
