Orosur Mining Inc. - Q3 2018 Results

MONTEVIDEO, Uruguay, April 16, 2018. Orosur Mining Inc. (“Orosur” or “the Company”) (TSX/AIM: OMI), a

South American-focused gold producer , developer and explorer announces its unaudited results for its third

quarter ended February 28, 2018 (“Q3 18” or the “Quarter”) . All dollar figures are stated in US$’000 unless

otherwise noted.

HIGHIGHTS

• In Colombia, high grade drilling continued at APTA during the Quarter with results from the current

diamond drilling campaign including 4.89 g/t Au over 13.9m, 4.86 g/t Au over 25.0m, 9.42 g/t Au over

7.0m, 9.62 g/t Au over 6.0m and 5.28 g/t Au over 12.0m.

• This campaign has already extended the known mineralization at APTA down dip, up dip and along

strike with early indications at the present drilling at Charrascala appearing promising.

• In Uruguay, following definition of a weaker mineralized structure at S an Gregorio (SG) UG at depth

and to the East in Q2 18 , the mine plan and sequencing was redesigned with SRK to optimise

economics, including the cancellation of development of deeper stopes from the previous mine plan

and incorporation of marginal stopes from current levels at SGW into Q3 18.

• As a result, Q3 18 production grades declined and production in the Quarter was 6,859 oz of gold,

which is below original expectations, and compares to 7,820 oz in Q3 17.

• In the current quarter, the Company expects an improvement in grades and lower capital expenditure.

However, as a result of the lower grades processed in Q2 18 and Q3 18, and with an increased focus

on profitability and not purely ounces produced, the Company’s production guidance has been

reduced to 27,000 – 30,000 oz Au from 30,000 oz , as well as an increase in the operating cash cost

guidance to US$900 - US$1,000/oz from US$800 – US$900/oz.

• Development work in Q3 18 focused on the shift of mining activities f rom SGW to SG Central and

included the completion of a 230m tunnel to provide access to the first planned stope at SGC towards

the end of the Quarter. The Company also finalised the pre -stripping of the Sobresaliente open pit

which is planned to be mined in Q4 18 as well as finalised the fourth phase of the tailings dam which

is planned to provide tailings storage for the next 36 months.

• During the Quarter, and in large part due to the performance of the SG UG, the Company commenced

the implementation of a strategic initiative to reduce costs and corporate structure aimed at improving

profitability and preserving cash. The Company continuously considers strategic options and is

currently in discussions regarding several alternatives to bolster capital resources available for its suite

of projects.

COLOMBIA EXPLORATION HIGHLIGHTS

On February 20 th and April 4 th, the Company reported high grade drilling and assay results from its current

step-out drilling campaign at APTA in Colombia from 18 holes drilled to date (MAP_054 to MAP_071) totaling

6,314 metres, including 4.89 g/t Au over 13.9m, 4.86 g/t Au over 25.0m, 9.42 g/t Au over 7 .0m, 9.62 g/t Au

over 6.0m and 5.28 g/t Au over 12.0m. Recent drilling in this campaign has extended the known mineralization

at APTA down dip, up dip and along strike. Mineralization remains open along strike and at depth at APTA.

Of the 18 holes drilled to date in this exploration campaign, 6 holes (33%) have intercepted mineralised

intervals grading in excess of 10 g/t Au.

Orosur is presently finalising the last phase of this exploration campaign focusing on maiden scout drilling at

Charrascala, the highest priority untested target, located 1.5 km to the west of the APTA discovery. Preliminary

indications at Charrascala appear positive, with drilling of the first hole having encountered sulphide

polymetallic mineralization (pyrite, chalcopyrite and sphalerite) associated with a set of structures with intense

silicification. Assay results of the five planned drill holes at Charrascala are expected to be received during

May 2018 and announced shortly thereafter.

OPERATIONS IN URUGUAY AND FY18 OUTLOOK

The broader San Gregorio underground mine (SG UG) is a continuation of the San Gregorio open pit deposit

at depth. The historic open pit produced approximately 536,000 oz of gold at an average grade of 2.12 g/t Au.

Since November 2016, the SG UG West (SGW) has been the primary source of ore feed to the plant. Mining

in the SGW sector is forecast to be complete in H2 18 when development and initial production of SG UG

Central (SGC) commences. SGC is planned to be the main source of underground ore feed to the plant during

the remainder of H2 18 and H1 19. The current mine plan then assumes continuation of ore production shifting

from SGC to SG UG East, followed by the Veta A underground project.

Isometric view of San Gregorio Pit & SG UG deposits at the end of Q3 18, including tunnel & development to SGC. Not to scale.

In Q2 18, a revised block model for SGC was finalized showing that the mineralized structure to be less

economically viable at depth and to the East of the sector with reductions in both ore grade and thickness. To

date, SG UG has produced 465,943 ton nes at 1.49 g/t Au (approximately 22Koz Au) , representing

approximately a 30% reduction in grade from historical SG open pit operations, which delivered an average of

2.12 g/t Au.

Following definition of this weaker mineralized structure at SG UG , the Company redesigned the mine plan

with SRK Argentina (“SRK”) and changed its sequencing for Q3 18. Development into deeper stopes was

removed from the mine plan and marginal stopes from current levels at SGW were incorporated into Q3 18 in

order to optimise economics based on development costs already incurred . As a consequence of these

initiatives, Q3 18 grades declined and production was approximately 2,000 oz below expectations. In an effort

to partially compensate for this production shortfall, additional rem nants from open pit reserves were mined

during the Quarter.

Primarily as a consequence of these lower grades, Q3 18 production was 6,859 oz of gold, compared to 7,820

oz in Q3 17 with average cash operating costs for the Quarter of $1,065/oz, compared to $858/oz in Q3 17.

During the Quarter, development work focused on the shift of mining activities from SGW to SGC completing

a 230m tunnel, which provided access to the first planned stope at SGC towards the end of the Quarter. In

addition, the Company finalised the pre-stripping of the Sobresaliente open pit which is planned t o be mined

in Q4 18 as well as finalised the fourth phase of the tailings dam which will provide tailings storage for the next

36 months, or until March 2021, on the basis of the current mine plan. All-In-Sustaining Costs (“AISC”) were

$1,395/oz compared to $1,289/oz in Q2 17, an increase of 8%.

The Company expects in Q4 an improvement in grades and lower capital expenditure. However, with the

lower grades processed in Q2 18 and Q3 18 and with an increased focus on profitability and not purely ounces

produced, the FY 18 production guidance has been reduced to 27,000 – 30,000 oz Au from 30,000 oz and the

Company’s operating cash cost guidance increased to US$900 – US$1,000/oz from US$800 – US$900/oz.

During the Quarter, and in large part due to the performance of the SG UG, th e Company commenced the

implementation of a strategic initiative to reduce costs in Uruguay and corporate structure aimed at improving

profitability and preserving cash. As part of this initiative, during Q3 18, greenfield exploration was suspended

and non -essential corporate and support costs have been drastically reduced , with Directors and officers

agreeing to reduce their fees and salaries by 20%. Further, the Company plans to discontinue mining from

marginal open pits during Q4 18. As a part of this initiative, a reduction of 1 20 staff members has occurred

from November 2017 to the end of March 2018.

The Company is currently accelerating its preparation of Veta A, a new underground project that is 1.2km from

the plant. In March 2018, the Company submitted a permit application to DINAMA, the environmental agency

in Uruguay. Initial work indicates Veta A is currently the highest-grade source of underground ore avail able

in the San Gregorio mine complex. Veta A was previously mined as an open pit, producing 29,000 oz with an

average grade of 3.1 g/t between September 2006 and March 2008. Reserves at the end of May 2017 we re

9,440 oz (122,328 tonnes at 2.40 g/t Au) and the Company is targeting a significant increase in reserves after

proving the continuity and extension of the ore body over 140 metres from the current defined reserves while

it remains still open at depth and along strike.

The Company continuously considers and analyses strategic options and potential partnerships to develop its

Uruguayan, Colombian and Chilean assets to create shareholder value and is currently in discussions on

several alternatives to bolster capital resources at its suite of projects.

Q3 18 FINANCIAL SUMMARY

• Operating profit was $1,168 compared to an operating profit of $1,848 in Q3 17.

• Loss after tax was $1,976 compared to a profit of $363 in Q3 17. This was mainly due to higher

depreciation and the recognition of a provision for staff retrenchments.

• Cash flow from operations before changes in working capital was $(155) compared to $1,674 in Q2

17.

• The Company invested $1,753 in capital expenditures and $1,236 in exploration compared to $3,218

and $449 respectively in Q2 17. The Company significantly increased its exploration as a result of the

current drilling campaign in Colombia.

• The Company’s cash balance at February 28, 2018 was $1,392 compared to $3,357 at May 31, 2017.

The Company has drawn on the Santander line of credit in the amount of $1,500 during Q3 18.
