*See tables below for assumptions used in the estimates.
"We are very pleased with this maiden reserve and resource estimate at Amancaya. It confirms the high grade nature of the
Amancaya project and our expectation that Amancaya will play a significant part in our growth plans," stated Stabro Kasaneva,
CEO of Austral Gold. "The Amancaya project is a unique asset; high grade gold and silver vein outcropping at surface that is
fully permitted, pre-stripping has commenced and ore is being stock piled, pending the imminent commissioning of the new
processing plant. The pre-feasibility study that evaluates the combined production from the Amancaya project with the operating
Guanaco mine, including its new processing plant, is expected shortly. We are expecting that this study will reveal a financially
robust combined operation located in a very attractive jurisdiction."
Amancaya Reserve and Resource Estimate
RPA undertook the study based on company infill drilling and exploration activities completed in 2016 and previous work done
on the project by other companies. Full details and assumptions used will be available when the Technical Report summarizing
the Pre-Feasibility study is filed on SEDAR and ASX within 45 days.

Notes:
1.
Mineral Reserves followed CIM Definitions, 2014 and are compliant with the JORC Code, 2012.
2.
Underground Mineral Reserves are estimated at a break-even cut-off grade of 2.5 g/t AuEq for stopes and an incremental cut-
off grade of 1.5 g/t AuEq for drifts.
Open Pit Mineral Reserves are estimated at a cut-off grade of 1.53 g/t AuEq.
3.
Mineral Reserves are estimated using an average long-term gold price of US$1,300 per ounce and silver price of US$20 per
ounce.
4.
Gold Equivalents (AuEq) were calculated as AuEq = Au + 0.0134 x Ag, based on a Au and Ag price of $1,300/oz and $20/oz
and recoveries of Au and Ag of 92% and 80%, respectively.
5.
A minimum mining width of 1.5 m was used for stopes and 3.5 m for drifts.
6.
Stope dilution: 0.5 m in the hanging wall and 0.5 m in the footwall (1.0 m total).
7.
Drift dilution: 0.25 m in each of the side walls (0.5 m total).
8.
Bulk density is 2.5 t/m

Notes:
1.
Mineral Resources followed CIM definitions, 2014 and are compliant with the JORC Code.
2.
Mineral Resources are reported inclusive of Mineral Reserves.
3.
Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability.
4.
Open pit Mineral Resources are reported at a cut-off grade of 1.5 g/t AuEq.
Pit optimization shells were used to constrain the
resources.
Underground Mineral Resources are estimated at a cut-off grade of 2.5 g/t AuEq beneath the open pit shells.
5.
Mineral Resources are estimated using a long-term gold price of US$1,300 per ounce, and a silver price of US$20 per
ounce.
6.
Gold Equivalents (AuEq) were calculated as AuEq = Au + 0.0134 x Ag, based on a gold and silver price of $1,300/oz and
$20/oz and recoveries of gold and silver of 92% and 80%, respectively.
7.
Minimum width for the open pit resource is 1.0 m and 1.5 m for the underground resource.
8.
Bulk density is 2.50 t/m

.
9.
Numbers may not add due to rounding.
The very high conversion rate (approximately 87%) of the Indicated resource into reserves in the Amancaya maiden reserve
estimate is a result of the consistent form and grade of the deposit.

"believes" and words of similar import tend to identify forward-looking statements.
Forward-looking statements in this news
release include the Company's expectation that the project will play a significant part in its growth plans, its expectation the
commissioning of its new processing is imminent, its expectation that the complete pre-feasibility study the combined production
at Amancaya and Guanaco is expected shortly, as well as its expectation of what that study will reveal. All of these forward-
looking statements are subject to a variety of known and unknown risks, uncertainties and other factors that could cause actual
events or results to differ from those expressed or implied, including, without limitation, business integration risks; uncertainty of
production, development plans and cost estimates, commodity price fluctuations; political or economic instability and regulatory
changes; currency fluctuations, the state of the capital markets, uncertainty in the measurement of mineral reserves and resource
estimates, Austral's ability to attract and retain qualified personnel and management, potential labour unrest, reclamation and
closure requirements for mineral properties; unpredictable risks and hazards related to the development and operation of a mine
or mineral property that are beyond the Company's control, the availability of capital to fund all of the Company's projects and
other risks and uncertainties identified under the heading "Risk Factors" in the Company's continuous disclosure documents
filed on SEDAR.
You are cautioned that the foregoing list is not exhaustive of all factors and assumptions which may have been
