June 09, 2017 8:00 AM EDT | Source: Austral Gold Limited

Vancouver, British Columbia--(Newsfile Corp. - June 9, 2017) - Austral Gold Limited (ASX: AGD) (TSXV: AGLD) ("Austral" or the "Company") is pleased to provide additional information to support positive and robust pre-feasibility results. This information is to supplement the mineral resource and reserve estimate for the Amancaya Project and Guanaco Mine, Chile, disclosed in the Company's announcement dated June 8, 2017.

Highlights:

  • After-Tax Net Present Value (NPV) at 7.5% discount rate is US$66.6 million for the Project.

  • All-In Sustaining Cost (AISC): US$831/oz Au.

  • The mine life is five years, based on Mineral Reserves.

  • Combined estimated annual average production of 53,000 ounces of gold and 370,000 ounces of silver.

  • Mine life capital totals $48.1 million, including reclamation and closure.

  • Average operating cost over the mine life is $112 per tonne milled.

  • Metallurgical recovery is estimated at 92% for gold and 80% for silver.

  • Gold and silver at refinery 99.9% and 99.0% payable, respectively.

  • Metal prices: Life of Mine ("LOM") average of US$18.88/oz silver and US$1,284/oz gold, based on consensus of independent forecasts for annual prices.

  • Net Smelter Return includes doré refining, transport, and insurance costs. Royalties of 3% for Guanaco and 2.25% for Amancaya are deducted.

  • Income taxes are 25% in 2017, 25.5% in 2018, and 27% for the remaining years in the LOM.

Stabro Kasaneva, CEO of Austral Gold stated, "We are very pleased that the results of the pre-feasibility study show robust project economics justifying the investments we have made in pushing forward with construction of the Amancaya operation and the investment in the new agitation leach processing plant. The combination of the two operations provides us with a very robust operation for the next five years. The very high conversion of the Amancaya resource to reserves underlies the consistent nature of the vein."

All Resources reported are inclusive of Reserves. A full description of assumptions shall be provided in a Technical Report in accordance with CIM Definitions 2014, National Instrument 43-101 and JORC code, to be filed under the Company's profile on SEDAR and ASX by July 24, 2017.

Summary of the Combined Operation

The Guanaco Project (the Project) comprises the operating Guanaco Underground Mine and the Amancaya Open Pit and Underground Project (open pit mining at Guanaco was completed in 2013). Amancaya is a satellite deposit with similar characteristics to Guanaco and will be processed at the Guanaco Mine and Mill Complex. The Mineral Reserves at Amancaya are based on the conversion of Mineral Resources using modifying factors (mining, economic, marketing, legal, environmental, social, and governmental) which were determined based on the current mining operations at Guanaco.  

The underground operations at Guanaco currently produce approximately 1,000 tpd. The open pit at Amancaya is expected to produce 400 tpd, followed by underground production of approximately 800 tpd. Each operation will overlap to produce an average mill feed of approximately 1,000 tpd during peak production in 2017 and 2018. Ore from Amancaya will be hauled by contractor via a 75 km road to the new mill located at the Guanaco mining complex. The mill, which was commissioned in March 2017, is designed to process up to 1,500 tpd using crushing, grinding, cyanide leaching, and Merrill Crowe to produce a doré. The Guanaco mine has produced approximately 50 koz per year for the last four years and the Company expects to continue at this rate for the remaining five years of the life of mine (LOM) plan. Guanaco is a mature operation with established infrastructure to support mining at Guanaco and Amancaya.

Capital costs for the new plant and most of the Amancaya infrastructure were incurred in 2016, and as such costs for combined operation of both projects are considered as sustaining capital, and included in the capital cost projection of $48.1m. As the Company has already built the Amancaya infrastructure there is no additional expected capital funding requirement. This, however, remains uncertain and the Company will assess any funding needs.

Environmental studies and environmental permits have been issued to support mining at Guanaco and Amancaya.
