Augustus Minerals Ltd (ASX:AUG) has extended its Justinian copper-gold prospect over 3 kilometres, in addition to picking up gold assays of 5.3 grams per tonne of gold and 16% copper through rock chip sampling.

The company reviewed data from follow-up fieldwork done earlier in the year at its Ti-Tree project over a 3.3 and 1.1 kilometre area, picking up the high-grade rock chips and finding that their mineralisation backs up the results of anomalous soil sampling in a recent regional survey.

The Justinian prospect was also found to have anomalous values for lead and zinc, and Augustus intends to carry out more sampling there to define and delineate its mineralised structures in preparation for drilling work.

Soil sampling also enabled extensions and discoveries in other parts of the Ti-Tree project, including Crawford West, Coo Creek, Howell’s Gap and Moogooree, with copper-gold-zinc anomalies extended by 1.5 kilometres to the west of Crawford Bore, which had been subject to drilling last year.

Anomalous gold values (more than 5 parts per billion) were also discovered west of the Coo Creek Broken-Hill style massive sulphide target.

Ti-Tree is part of Augustus’ holdings in the Gasgoyne region of Western Australia, totalling an area of around 3,600 square kilometres.

Shares in the company rose on the news, and at 10:23 AEDT, they were trading at 5.4 cents – an increase of 12.5% since the market opened.
