Results confirm the strong alteration and significant zinc mineralisation intersected at Nhill requires follow-up drillingAustpac (ASX code: APG) is encouraged by the additional results from Nhill and is pleased to advise that:
The analyses of the second batch of samples confirm and extend the zinc plus accessory copper- gold mineralised zone intersected in GG-01, the company's first diamond drillhole within EL 5291 Nhill.
The strong pervasive alteration of the basement volcanics and the highly anomalous zinc mineralisation (up to 3.6% Zn and 0.44g/t Au) are typical of the outer halo of a nearby porphyry- style hydrothermal system.
Step out drilling is required to locate the source in this unexplored region of western Victoria.
In May 2017, Austpac completed one exploration drill hole to test the basement rocks for copper-lead-zinc mineralisation under a thick cover of much younger Murray Basin sediments. The program is being co- funded by the Victorian Government under the TARGET Minerals Exploration Initiative. The drill target was developed using recently acquired magnetic and gravity data and the innovative geological concepts developed by the Geological Survey of Victoria. The vertical hole, DH GG-01, passed through the cover sediments using mud rotary equipment and encountered competent basement at 248.9m. Diamond core drilling was then used to continue the hole for a further 75.6m and the hole was terminated at 324.5m.
The basement consists primarily of basaltic volcanics which, apart from two very narrow sections in the hole, have been strongly to intensely altered by hydrothermal fluids. The alteration is accompanied by sulphide mineralisation, which was deposited primarily as pyrite (iron sulphide) in fractures, along breccia boundaries and in vughs/amygdales (voids). The pyrite is often accompanied by significant amounts of sphalerite (zinc sulphide) and minor amounts of finely disseminated chalcopyrite (copper sulphide) and anomalous gold.
The results from initial 38 core samples submitted for analysis were very encouraging, as described in the Company's recent Quarterly Report to the ASX dated 30 July 2017.
Two intervals contain abundant visible sphalerite and pyrite mineralisation:
0.5m at 3.6% Zn with 0.44 g/t Au (intercept downhole from 308.0m to 308.5m). This included an 8cm section containing 15% sphalerite and 8% pyrite together with silica flooding (see photo).
0.5m at 1.2% Zn with 0.20 g/t Au (intercept downhole from 324.0m to 324.5m; end of the hole).

In July 2017, an additional 31 drill core samples were analysed to fill in the gaps in the initial batch of samples. The results show that the zone of strongly anomalous base metals and gold extends over a broader interval within hole GG-01 than previously known. The additional results are highlighted in light grey in the table below, and anomalous results are marked in bold and an asterisk*.
The basaltic volcanics encountered at the base of drill hole GG-01 at Nhill are considered analogous to parts of the Cambrian Mount Stavely Volcanic Complex, ~170km to the southeast, where results of recent drilling intersected porphyry-style copper-gold mineralisation. Exploration in the Mallee region of western Victoria has been hampered by the thick cover of Murray Basin sediments. The mineralisation encountered in GG-01 is highly encouraging considering it is the first hole drilled in this previously untested terrain.
The strong alteration and mineralisation encountered in GG-01 is the result of the introduction of mineral- rich fluids into permeable fractures and breccia zones. The mineral assemblage observed is typical of the outer halo of a hydrothermal system, the source of which is offset from present drill hole. However, the distance and direction of its source cannot be assessed with a single drill hole and step-out drilling is required to fully test this hitherto unexplored region.
Below is a photograph of a 6cm section of core from 308.0m from the upper breccia zone:
