Austral Gold provides Update on Exploration Activities
Austral Gold Limited (the “Company” or “Austral” ) (ASX: AGD; TSX-V: AGLD) is pleased to provide an update on its on-going exploration programs in Chile and Argentina.
Highlights:
- At Amancaya , three of six drill holes in the Sur vein confirmed the continuity of DAM003 as previously announced on 27 January 2021 and two of the five follow-up drillholes in the Oeste vein confirmed the continuity of the structure at depth. The most significant results obtained were:
DAM-028 0.60 meters @ 84.25 g/t gold and 7.0 g/t silver (Sur Vein) DAM-029 0.81 meters @ 24.70 g/t gold and 1.9 g/t silver (Sur Vein) DAM-032 2.26 meters @ 5.72 g/t gold and 5.3 g/t silver (Sur Vein) DAM-035 1.50 meters @ 20.06 g/t gold and 4.8 g/t silver (Oeste Vein) DAM-036 2.82 meters @ 6.13 g/t gold and 2.5 g/t silver (Oeste Vein)
- At Sierra Inesperada , the latest drilling results confirmed silver mineralisation vectoring to potential blind gold mineralisation in the Purisima breccia complex. The most significant results obtained were:
DIN-018B 98.50 meters @ 19.2 g/t silver
(Include 24.0 meters @ 51.5 g/t silver and sub-include 8.20 meters @ 0.25 g/t gold) DAM-027 129.00 meters @ 34.0 g/t silver
(Include 55.0 meters @ 63.6 g/t silver and sub-include 4.00 meters @ 0.27 g/t gold)
- At Casposo – Manantiales district, the first phase of drilling was completed in five vein targets. At Manantiales vein , a blind ore-shoot was intercepted opening the upside to the south. The most significant results obtained were:
MDH-021-56 1.44 meters @ 6.88 g/t gold and 10.6 g/t silver
MDH-021-57 1.50 meters @ 5.05 g/t gold and 10.3 g/t silver
- At Sierra Blanca , the first tranche to acquire 51% of the project was completed. To date the Company has incurred exploration expenses of US$145,000 and is focused on acquiring the next 29% interest, which requires an additional US$555,000 in exploration expenses be incurred over the next two years.
The exploration activities are designed with a focus on the Company´s growth strategy as follows:
-
Expand the resource at the Guanaco/Amancaya mine complex,
-
Explore Tier I or Tier II high sulfide (“HS”) projects (Sierra Inesperada, Cerro Buenos Aires, Cerro Blanco, and Morros Blancos),
-
Restart the Casposo-Manantiales mine complex, and
-
Increase the mineral resources inventory at the Pinguino-Sierra Blanca cluster

Chief Executive Officer, Stabro Kasaneva commented: "We have seen excellent results on exploration activities in Argentina and Chile. Of particular interest are the high-grades and shallower depths that have been intersected in the Oeste structure at Amancaya, with more drilling to follow. At Sierra Inesperada, we are vectoring into a potential gold source at the complex, having intersected a silver halo surrounding the potential feeder. In addition, we look forward to receiving our updated mineral resource and mineral reserve estimates at our GuanacoAmancaya mine complex during Q1 2022.”
Amancaya Mine Exploration
During Q3 2021, follow-up and categorisation programs at Amancaya were completed with 14 drill holes (DAM-027 to DAM-040). The most significant results were obtained in the Oeste Vein, where two follow-up drill holes confirmed 100 meters of vertical continuity of the structure in the previous drilled sections, while a third drill hole (DAM-040) in a section in between, cut the structure in depth where a narrow structure with a low grade was observed.
At Veta Este, the continuity of the structure on the proposed strike was not confirmed, as the follow-up program intercepted only narrow veins with drillholes DAM-33 and DAM-034. The interpretation suggests that it is a gently east dipping splay structure between the North and South veins.
Paleocene HS Districts Exploration
At Sierra Inesperada , four targets were tested with 20 diamond drillholes in two phases, confirming HS hydrothermal activity controlled by phreatomagmatic complexes and associated with silver mineralisation. Integration of geological, geophysical, and geochemical interpretations suggest potential blind gold mineralisation which we plan to test during Q4 2021.
At Cerro Buenos Aires , three drilling targets were defined with delineation activities that included detailed geological mapping, CSAMT geophysical survey and systematic rock geochemistry. A first phase of five drillholes was initiated and preliminary geological drilling results provide evidence of multi-event phreatomagmatic breccias, greater than 300 meters of oxidized HS alteration column including greater than 100 meters of strong silicification and relict vuggy silica.
At Morros Blancos , the targeting process defined three prospective HS areas. Delineation began in Rosario del Alto, which we ranked as having the greatest potential. Initial geological mapping recognized four maar – diatreme complexes with favorable alteration at the right level preservation. Systematic rock geochemistry and CSAMT survey was initiated and we plan to commence a drilling program in Q4 2021 if positive results are received.

Casposo – Manantiales District Exploration
The first phase of drilling was completed in five vein targets including 14 holes in 2,800 meters. At the Manantiales vein, a blind ore-shoot was intercepted opening the upside to the south and the exploration potential to the north in the protected block related to the Vallecito reverse fault.
The holes drilled at Valentina, Julieta, Awada and Maya did not intercept significant mineralisation. However, the composition and textures of the intercepted veins suggest potential at depth. A second drill phase is under review and is expected to be completed during Q4 2021.
Pinguino – Sierra Blanca District Exploration
Preliminary targeting of the district, based on geological mapping, Aster interpretation, and geophysics resulted in a new target structurally protected. The follow-up activities on the new target confirmed favorable alteration related to Dome-Breccia complex. Our planned Q4 2021 activities are focused on relogging and reinterpretation of historical data.

Forward Looking Statements
Statements in this news release that are not historical facts are forward-looking statements. Forward- looking statements are statements that are not historical and consist primarily of projections - statements regarding future plans, expectations and developments. Words such as "expects", "intends", "plans", "may", "could", “potential”, "should", "anticipates", "likely", "believes" and words of similar import tend to identify forward-looking statements. Forwardlooking statements in this news release include our plans for more drilling at Amancaya, we plan to test during targets at Sierra Inesperada in Q4 2021, a second drill phase is expected to be completed during Q4 2021 at the Casposo - Manantiales District, our planned Q4 2021 activities at the Pinguino – Sierra Blanca District are focused on relogging and reinterpretation of historical data, and the expectation that we will receive updated mineral resource and mineral reserve estimates at our Guanaco-Amancaya mine complex during Q1 2022.
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 especially in light of the effects of the novel coronavirus, 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 the ASX and on SEDAR. You are cautioned that the foregoing list is not exhaustive of all factors and assumptions which may have been used. Austral cannot assure you that actual events, performance or results will be consistent with these forward-looking statements, and management’s assumptions may prove to be incorrect. Austral’s forward-looking statements reflect current expectations regarding future events and operating performance and speak only as of the date hereof and Austral does not assume any obligation to update forward-looking statements if circumstances or management’s beliefs, expectations or opinions should change other as required by applicable law. For the reasons set forth above, you should not place undue reliance on forward-looking statements.

The Amancaya project represents a | ||

deposit. The Amancaya vein system is |
|||
related to a phreatomagmatic breccia |
|||
| complex hosted in the Palaeocene | |||
| andesitic sequence and controlled by | |||
| NS and NW faults. The mineralisation | |||
| and alteration are focused along high- | |||
angle structures in an intra-mineral |
|||
| tuffaceous matrix breccia. The fault | |||
| system provided a pathway for rising | |||
| hydrothermal fluids. The Norte, Sur | |||
Central and Oeste Vein exhibits |
|||
| banded textures, with bands of grey | |||
chalcedonic quartz, clear crystalline |
|||
quartz, amethyst, and dark bands |
|||
| containing sphalerite, silver, and lead | |||
sulphosalts. Other textures include |
|||
| coloform texture, sinuous alternating | |||
bands of chalcedonic quartz and |

| amethyst, and crustiform quartz. |

| Interstices are filled with clays, |

| Geology | •Deposit type, geological setting and | Casposo | |
style of mineralisation. |
• | The mineralisation identified | |
| within the Casposo Property is an | |||
example of low sulphidation |
|||
| epithermal deposition of gold and | |||
| silver. | |||
| • | The gold–silver mineralisation at | ||
Casposo is structurally controlled |
|||
and occurs in crustiform- |
|||
| colloform quartz veins and | |||
| stockworks, | |||
| • | Native metal alloys of gold and | ||
silver are present as minute zoned |
|||
| grains that vary up to 100μm in | |||
| the longest dimension. These | |||
grains are enclosed by gauge |
|||
| minerals, along the contact with | |||
sulphosalts and as inclusions in |
|||
| sulphosalts. The alloys are | |||
| typically zoned with gold-rich cores | |||
and mantled by more silver-rich |
|||
| margins. | |||
| Manantiales | |||
| • | The style of mineralisation is | ||
essentially a gold-silver, quartz- |
|||
| adularia low sulphidation epithermal | |||
| system in the proximity of epizonal | |||
intrusives, with low pyrite (< 1%) |
|||
| and minor clay alteration. | |||
| • | The Manantiales project lies within |
||
| a variably dipping sequence of | |||
felsic pyroclastics and tuffaceous |
|||
volcaniclastics belonging to the |
|||
| Permo-Triassic Choiyoi Group. | |||
Locally, these rock units have been |
|||
| intruded by felsic subvolcanic | |||
porphyries and dykes. |
|||
| • | Gold mineralisation is structurally | ||
controlled and occurs in crustiform- |
|||
| colloform quartz veins and | |||
| brecciated quartz veins and | |||
| siliceous breccias mixed with | |||
| variable amounts of late-stage | |||
calcite. |
