Orosur Mining Inc: 2017 Year End Operations Update

SANTIAGO, Chile, June 20, 2017. Orosur Mining Inc. (“Orosur” or the “Company”) (TSX/AIM: OMI), a South

America-focused gold producer, developer and explorer, is pleased to announce an operations and exploration

update for its year ending 31 May 2017 (“FY 2017”).

Highlights:

Operations

• Successfully built and developed the San Gregorio West underground mine in Uruguay (“SGW UG”)

from internal funds

• FY 2017 production of 35,371 oz (within stated guidance of 35-40 koz) following a significant increase

in production in Q4 (10,748 oz)

• Operating cash cost guidance of US$800 - 900/oz expected to be confirmed when full year 2017

results are announced in mid-August

• Cash balance at the end of May 2017 was US$3.3M (Q3 US$2.4M and FY 2016 US$4.3M) with debt

of just US$0.4.

Exploration

• In Uruguay, the Company is extending its mine life with a particular focus into the Central and East

areas of SG UG. SRK Consulting has been engaged to prepare a scoping study covering an expanded

SG UG project which will include not only the extensions to Central, East and Deeps, but also the

neighbouring deposits of Veta Sur, Ombú and Veta A.

• The deadline for Asset Chile (“AC”) to make its decision to finance Phase 2 in Anillo (which is

strategically located between Yamana`s El Peñon and Pampa Augusta Victoria) has been extended

to December 2017

- AC is expected to cover Anillo Spa corporate and ongoing costs until then, which are estimated

at approximately US$150k

- the first US$85k was received from AC on June 14, 2017

- under the extension agreement, Orosur is now able to have open discussions with alternative

partners to progress Anillo in the event AC does not elect to fund Phase 2

• The Company plans to commence a 15,000m - 30,000m drilling campaign in 2017 in Colombia ,

culminating in the preparation and publishing of a maiden N.I. 43 - 101 compliant resource report for

the APTA project. The Company will update the market once the exploration programme has been

designed and validated, and a drilling contractor engaged. Timing and scope of the drilling programme

will be driven by a combination of exploration results, funding requirements of the C ompany and

prevailing equity and gold market conditions.

Ignacio Salazar, CEO of Orosur, commented:

“We are delighted to have delivered in line with production targets for the fourth consecutive year. Exploration

and development work has been running in parallel with production at SGW UG this year allowing us not only

to open a new underground mine but also to expand it solely with internal funding from operations. While

2

emphasis on cost management, operational excellence and delivery remains an overriding priority for us, we

expect our focus on growth to deliver further results this next fiscal year initially centered on resource definition

in Colombia, tapping the potential of the 100km greenstone belt controlled by OMI in Uruguay and advancing

Anillo in Chile.”
