June 08, 2017 8:40 AM EDT | Source: Austral Gold Limited

Vancouver, British Columbia--(Newsfile Corp. - June 8, 2017) - Austral Gold Limited (ASX: AGD) (TSXV: AGLD) ("Austral" or the "Company") is pleased to announce that Roscoe Postle Associates Inc. ("RPA") has completed a new independent resource and reserve estimate in accordance with CIM Definition Standards, 2014 as incorporated in National Instrument ("NI") 43-101 and Joint Ore Reserves Committee Code, 2012 (JORC12) for the Company's 100% owned Amancaya project and Guanaco Mine, Chile. The Amancaya reserve estimate is the first in that project's existence.

Highlights:

Amancaya*:

●   

Total Indicated resource at Amancaya of 804,690 tonnes at 9.64 g/t gold and 80.7 g/t silver for 277,352 Gold Equivalent ("AuEq") ounces, including;

o   

A maiden probable reserve of 948,053 tonnes grading 6.77 g/t gold and 63.2 g/t silver for 232,074 AuEq ounces, including;

o   

A maiden open pit probable reserves of 254,596 tonnes grading 7.56 g/t gold and 119.5 g/t silver for 74,993 AuEq ounces

●   

Total inferred resource at Amancaya of 959,554 tonnes at 6.79 g/t gold and 36.1 g/t Ag for 220,000 AuEq ounces.

Guanaco*:

●   

Measured and Indicated resource of 2,193,000 tonnes grading 2.9 g/t gold and 13.0 g/t silver for 217,000 AuEq ounces, including;

●   

Total reserves of 489,635 tonnes grading 2.99 g/t gold and 3.6 g/t silver for 47,907 AuEq ounces, including;

o   

Proven reserve of 189,613 tonnes grading 3.41 g/t gold and 4.1 g/t silver for 21,106 AuEq ounces, and,

o   

Probable reserve of 300,022 tonnes grading 2.73 g/t gold and 3.4 g/t silver for 26,801 AuEq ounces.

●   

Inferred resource: 1,200,000 tonnes grading 2.6 g/t gold and 12.9 g/t silver for 110,000 AuEq ounces.

*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/m3.
9. Numbers may not add due to rounding.

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/m3.
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.
