This report, written by a very experienced consultant mining engineer (later the manager of the Broken Hill South Silver Mining Co.), addresses the known geology and mining history of the Kapunda copper mine from its opening in January 1844 until its economically enforced closure in February 1879 (after which time the only workings on the lodes were carried out by tributers, mining underground in haphazard fashion down to the ~80 foot depth of the water table). The author has examined in great detail available information on the nature and degree of exploitation of the identified lodes, and has formed the conclusion that the mine property is quite worthy of re-opening, since all indications are that these lodes and certain others recently discovered by his client's scout diamond drilling will persist for some appreciable depth below the lowest point reached by the previous underground mining. This opinion echoes that given by the SADM Chief Inspector of Mines, Captain W.H. Matthews, in his review made in 1905. Based on that former recommendation, the option holder undertook exploratory percussion drilling over the period 7/12/1906 to 31/5/1907, to investigate the viability of doing open cut mining below the water table, if the ground there could be dewatered by means of modern pumping equipment. At the Kapunda mine proper, 8 vertical holes were completed for a total penetration of ~1527 feet, the deepest hole being taken to a depth of 231 feet. At the Hillside mine, 2 further holes were completed for 337 and >264 feet respectively. Also at the Kapunda mine, 3 diamond drillholes were attempted to probe deeper beneath the historic underground workings, but due to frequent loss of drilling fluid circulation, and the mostly unsuitable nature of the country rock for cutting and retrieving intact cores, the sampling aspect of this drilling proved unsatisfactory. DDH 1 was taken vertically to a total depth of 750 feet; DDH 2 inclined at 65 degrees to the ESE also reached 750 feet; while DDH 3 inclined at 60 degrees towards near east was taken to 500 feet. Mr Wainwright has stated that un-mined lodes definitely exist at the Kapunda mine between the 420 foot and 480 foot level (3 lodes known from former miners' anecdotal evidence) and are expected to continue at depth, possibly running at a grade of 4% Cu or more, which is higher than the average grade of copper ore currently being mined profitably at Wallaroo-Moonta. Furthermore, based on the recent drilling work, un-mined lodes are known to exist below 155 foot depth at the abandoned Hillside mine, and are likely to run at 5% Cu or more. His expert advice regarding how to appraise these un-mined lodes is that initial underground development at Kapunda should be achieved by sinking a new, 600 foot deep shaft between the now collapsed-inward Harris and Stockyard shafts, while underground exploration at Hillside would require a new 400 foot deep shaft. From specified depths within these shafts several exploratory cross-cuts should be driven to access and sample the lodes. The optimal manner and estimated cost of achieving these goals are described in sufficient detail to enable the company to organise finance and procurement of equipment and personnel that will allow an immediate start on the work envisaged.
