The Plan supports the viability of moving to small scale underground mining methods and optimisation of the process plant. The positive results put us in a position to re-commence full operations. We look forward to continuing the operation of Casposo and working with the community to the benefit of all stakeholders."

"The results present an exciting opportunity for the Company and its shareholders, and it is a very significant moment for the company, representing our first operation in Argentina," remarked Austral Gold Chairman, Eduardo Elsztain. "The results confirm our expectations for Casposo, validating the original commitment of the Board of Directors, management, our investors and Argentina's stakeholders to push forward with recommissioning the operation and growing our precious metal production in Argentina and Chile."

CASH FLOW ANALYSIS

Project economics at an average gold price of $1,329/ounce and a silver price of $19/ounce, based on a consensus of independent forecasts for annual prices, resulted in Table 1.

The cash flow to be generated over the LOM are shown in Table 2;

COST SUMMARY

Average cost per ounce metrics for LOM are shown in Table 4;

CASH FLOW SENSITIVITY ANALYSIS

Economic risk analysis was examined by running cash flow sensitivities on Gold and Silver Price, head grade, recovery, operating costs and capital costs. The pre-tax NPV @ 5% was calculated for reasonable variations of each input.

The cash flow is most sensitive to metal prices and head grades as shown in Table 5. It is least sensitive to recoveries and capital costs (which are low given that Casposo is being recommissioned).

Austral is currently consolidating exploration and mining geology databases and is expecting to define and prioritise brownfield targets for future drilling.

By way of background, Austral acquired a 51% interest in Casposo from a subsidiary of Troy Resources Ltd. (Troy) on March 4, 2016 for $1,000,000, with a reciprocal purchase and sale obligation for an additional 19% interest for the sum of $1,000,000 to be transferred and paid on March 4, 2017. In addition, Austral and Troy have agreed that Casposo will pay Troy $2,000,000 within 12 months as from March 4, 2016, out of which $1,000,000 has been already paid. In turn, Austral has options to acquire: (i) an additional ten percent (10%) for $1,500,000 within the period commencing on December 31, 2018, and ending on January 15, 2019, (ii) an additional ten percent (10%) for $2,500,000 within the period commencing on December 31, 2019, and January 15, 2020, and (iii) the last ten percent (10%) for $3,000,000 within the period commencing on December 31, 2020, and ending on January 15, 2021. These purchase price options may be subject to an adjustment based on an increase in the price of silver during such period. Pursuant to the Troy Agreement, Austral agreed to obtain from other sources or provide to Casposo funding or financing of up to US $10,000,000 towards developing and implement a re-engineering plan to recommission Casposo.

Life of Mine Plan Details

RPA reviewed and validated the Mineral Resource, Mineral Reserve, production schedule, and cost estimates for the Casposo operations as received from Austral.

For information with respect to the key assumptions, parameters and risks associated with the estimates included therein and other technical information, please refer to the Technical Report on the Casposo Gold-Silver mine to be filed on SEDAR within the next 45 days.

A summary of areas described in the Technical Report is included below:

Mineral Resources

The Mineral Resources for Casposo are contained in the Kamila (including Aztec, B-Vein Inca and Mercado zones), Julieta and Casposo Norte deposits and are summarised in Table 6.

In RPA's opinion, sampling and assaying have been carried out using industry-standard quality assurance/quality control (QA/QC) practices, and the resulting database is appropriate for use in Mineral Resource estimation.

In RPA's opinion, interpretations of the geology and the three-dimensional (3D) wireframes of the estimation domains are reasonable, and the resource estimates have been prepared using appropriate methodology and assumptions including: treatment of high assays, composite length, search parameters, bulk density, interpolation, cut-off grade and classification.

The Mineral Resources are classified and reported in accordance with Canadian Institute of Mining, Metallurgy and Petroleum Definition Standards for Mineral Resources and Mineral Reserves dated May 10, 2014 (CIM definitions) as incorporated in NI 43-101, as well as JORC 2012.

Notes:

1. Mineral Resources were estimated in compliance with both CIM and JORC definitions.
2. Mineral Resources are estimated using an average long-term silver price of $15 per ounce, and a gold price of $1,200 per ounce.
3. Mineral Resources are estimated at a cut-off grade of 2 g/t Au Eq.
4. Gold equivalents (Au Eq) are calculated using a factor of 1 g Au = 81 g Ag, based on metal prices, and metallurgical recoveries (92% for gold, 87% for silver).
5. A minimum wireframe width of 0.5 m was used.
6. Bulk density is 2.6 t/m³.
7. Mineral Resources are inclusive of Mineral Reserves.
8. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability.
9. Numbers may not add due to rounding.
10. The Qualified Person (QP) is Chester Moore, P.Eng., an employee of Roscoe Postle Associates ("RPA").

The Kamila deposit remains open down plunge to the southeast of the Inca 3 zone. The Casposo Norte and Julieta zones are not completely delineated and many smaller targets on the property remain to be fully explored.

Mineral Reserves and Mining

The estimated Mineral Reserves are shown in Table 7.

Notes:

1. Mineral Reserves were estimated in compliance with both CIM and JORC definitions.
2. Mineral Reserves were estimated at a cut-off grade of 2.8 g/t Au Eq. Development was evaluated at an incremental cut-off grade of 1.3 g/t Au Eq.
3. Gold equivalents (AuEq) were calculated using a factor of 1 g Au = 81 g Ag, based on metal prices and metallurgical recoveries (92% for gold, 87% for silver).
4. Mineral Reserves were estimated using an average long-term silver price of $15 per ounce and gold price of $1,200 per ounce.
5. A minimum mining width 2 m was used.
6. Bulk density is 2.6 t/m³.
7. Numbers may not add due to rounding.
8. The Qualified Person (QP) is Jason Cox, P.Eng., an employee of Roscoe Postle Associates ("RPA").

There are no known mining, metallurgical, infrastructure, permitting, or other relevant factors that could materially affect the Mineral Reserve estimate.

Planned and unplanned dilution, minimum mining width, and extraction were included in the resource to reserve conversion at the stope optimization and design stage. The design shapes were drawn to represent final mined out volumes. An extraction factor of 95% is applied to both stopes and drifts. Dilution included in the design averages 33% across all veins (stopes and development).

MINING METHODS

The Casposo Mine consists of a number of narrow steeply dipping orebodies known as Aztec, B-Vein, B-Vein1, Inca0, Inca1, Inca2A, Inca2B, Mercado, and Julieta. Open pit mining in Kamila and Mercado pits was completed in 2013, and all mining is currently planned as underground, although there is potential for open pit mining at Julieta. The main production from the underground mine to date has been from Inca1, Aztec, and Inca2A.

The mining method at the Casposo Mine is expected to be Longitudinal Longhole Retreat, which was the historical method used at the mine. Mine production is expected to be made up of a combination of ore development through sill drifts (34%) and stope production (66%).

Austral is modifying previous operating practices in a number of ways to better control dilution:

• Reduced stope heights from 20 m to 15 m.
• Smaller drift size (4.5 m by 4.5 m)
• Installation of cable bolts on the hangingwall.
• Revised blasting practices.

The veins are to be accessed by sub-level footwall drives, driven from the main ramp at 15 m intervals, except where pre-existing drives at 20 m intervals will be used. Stopes are designed using a minimum mining width of 2 m and are 10.5 m high, while sill drifts are designed at 4.5 m high and on average 4.0 m to 5.0 m wide. Stope lengths vary depending on the ore body, however, are limited to a maximum of 15 m due to geotechnical constraints.

Mining is planned to progress in a bottom up fashion. Stopes on each level are to be accessed in the middle and developed along strike, at both the top and bottom elevations. Once sill development is completed, the stopes are drilled and blasted. Drilling and blasting start at the end of the stoping blocks and mucked in retreating vertical slices.

PRODUCTION SCHEDULE

The production schedule covers a mine life of four years based on the Mineral Reserves outlined in the Casposo Technical Report. Austral has been engaged in the development and rehabilitation work at the Casposo mine since April 2016, and production is expected to begin by the end of Q3 2016 at Aztec, Inca1, Inca2A, and Inca2B, which are all accessible with current existing development. The production schedule is summarized in Table 8.

PROCESS

The processing and recovery method is whole ore cyanide leaching for extraction of the precious metal from the ore and Merrill-Crowe counter-current decantation (CCD) and filtration for recovery of the metal from the leach circuit. The Casposo Mine recovers gold and silver doré which is to be transported to a refining facility in Brampton, Ontario Canada for further processing into high purity gold and silver.

The Casposo processing plant has a nameplate throughput of 400,000 tpa of ore. The current underground mine plan delivers approximately 300,000 tpa of ore, and Austral plans to operate the plant on an intermittent basis to retain the nominal plant throughput.

Austral's plant modifications are expected to increase operational efficiency in the crushing and grinding circuits, and in tailings filtration and water management.

CAPITAL & OPERATING COST ESTIMATES

Austral has been carrying out a program of mine development, process improvements, and operational readiness since April 2016. The estimated capital costs (expressed in US dollars) from June 30, 2016 forward are summarised in Table 9.

Mine development is based on the LOM plan requirements, and a unit rate of $2,200/m, based on actual costs incurred at the mine.

Sustaining capital includes budgeted plant improvements, such as changes to the belt filter and cyanide detoxification circuit to improve efficiency and reduce costs, some mobile equipment purchases, and general site maintenance costs. Mountain Pass Consulting estimated reclamation and closure costs of $4.2 million.

Operating costs for the LOM plan are shown below in Table 10.

Operating cost estimates include mining, processing, and general and administration (G&A) expenses. Operating costs were budgeted based on costs incurred during previous mining activities and have been compiled by area based on estimated labour requirements, consumables, and other expenditures according to the updated mine plan and process design.

The power requirements will be met by the existing power line to site that has the capacity to transmit 18 MW of power, which is well in excess of the requirements of the operation.

SOCIAL & ENVIRONMENTAL

All required studies were completed and the Environmental Impact Assessment (EIA) for Casposo was submitted in 2007. It was reviewed by a multi-disciplinary commission, approved in 2009, and renewed every two years subsequently. The fourth update was presented recently, with approval due in March 2018.

Austral reports that it has all required permits to carry out operations. Calingasta is a mining town and the town is home to a Mining Technology school. As a result, in the view of RPA, the mine enjoys better than average local support. The social and community relations are reported to be excellent.

A Mine closure plan was prepared by Mountain Pass LLC (Mountain Pass) in December 2014.
