(\"ECR\") and Terramin Australia Limited (\"Terramin\" ASX: \"TZN\").\nFollowing the announcement of this information on the ASX, the trading halt has been ended and trading in the Company's securities has been restored on ASX.\nThor, as announced on 1 August 2017, is earning up to a 60% interest in ECR, which in turn is earning, from Terramin, up to a 75% interest in the mineral rights and claims over the portion of the historic Kapunda copper mine in South Australia recoverable by way of in situ recovery techniques. Subject to full earn in Thor would therefore hold an effective 45% interest in Kapunda.\nHighlights\n· An Inferred resource estimate of 47.4 million tonnes (MT) grading 0.25% Cu, containing 119,000 tonnes of contained copper;\n· Resource estimate is only for that part of the Kapunda deposit considered amenable to Insitu Recovery techniques;\n· Estimate includes mineralisation only from the top 100 metres of the deposit which host copper species (copper oxides and secondary copper sulphides) that are readily leachable;\n· The resource grade is well within the recommended ranges for In Situ recovery of copper and preliminary investigations of hydro geological parameters appear favourable;\n· Insitu recovery processes are not burdened by the normally high capital and operating cost activities of mining, crushing, grinding, and often flotation associated with conventional mining and processing operations. Subject to feasibility study outcomes at Kapunda, there is therefore an expectation that copper production from shallow deposits, amenable to ISR techniques may be at relatively low cost;\n· Further work is required to advance a range of areas prior to commercial development including ongo...
