Altona Mining Limited (“Altona”) is pleased to announce the results of the first four drillholes of the programme designed to test for extensions to the Kylylahti mine. The drilling has extended resources by 50-100 metres vertically to 850 metres deep and demonstrates that high grades continue at depth. • Intercept of 108 metres at 2.4% copper including 58 metres at 4.2% copper • Best drillhole result at Kylylahti deposit since discovery in 1984 Prior drilling at the bottom of the deposit is sparse and resource and reserve tonnes decline quickly below a vertical depth of 650 metres. This drilling not only extends mineralisation at depth but will increase the grade, width and confidence in the poorly defined resource model below 650 metres depth. Highlights of the drilling include: KU 902 108 metres at 2.4% copper, 1.0g/t gold, 0.8% zinc Including 58 metres at 4.2% copper, 1.2g/t gold, 1.0% zinc KU 901 107 metres at 1.0% copper, 1.4g/t gold, 0.4% zinc Including 34 metres at 2.0% copper, 0.7g/t gold, 0.6% zinc KU 900 87 metres at 1.1% copper, 0.8g/t gold, 0.6% zinc Including 15 metres at 1.8% copper, 0.4g/t gold, 1.0% zinc KE 1 102 metres at 0.8% copper, 1.0g/t gold, 0.2% zinc Including 12 metres at 2.0% copper, 2.6g/t gold, 0.7% zinc True width of intercepts ranges from 20 to 60 metres (see Figures 2 and 3). Notable are elevated gold grades well above the usual 0.5-0.7g/t range usually reported. Full results are appended in Table 1 and JORC requirements in Table 3. High grade semi-massive sulphide drill core averaging 8.1% copper and 2g/t gold. Dr Alistair Cowden, Managing Director of Altona said, “Kylylahti is a great orebody and it is a delight to report the best drillhole yet from the deposit since its discovery by Outokumpu in 1984. The drilling is spectacular providing a clear demonstration of high grades persisting at depth. These results provide the support to consider expanding production to 700,000 tonnes per annum, some 27% higher than the Feasibility Study design. Revised guidance will be issued when mine planning is completed and upon receipt of a revised resource and reserve estimate which will be released in conjunction with half year reporting early in 2014.” The deposit is structurally complex, however, knowledge from mining the deposit and detailed underground drilling has given a better understanding of structure and permits a reasonable interpretation of geometry at depth. The type example deposit in the Outokumpu copper field, Keretti, is some 4 kilometres long, up to 300 metres across plunge and up to 40 metres thick. Consistent high grades and elevated gold are characteristics of the better parts of Keretti, a deposit which produced over 1 million tonnes of copper and 1 million ounces of gold. Kylylahti is some 1.3 kilometres long from surface to the limit of drilling. At surface mineralisation is thin and weak and the deposit increases in grade and size with depth. The deposit remains open and there is a crude trend of improving grades and metal content with depth. Further drilling will be planned to test the deposit to 1 kilometre vertical depth. Given the analogy with Keretti and other deposits, there is no reason to expect the deposit will not extend further and that mining will only be limited by economics and ground conditions. Excellent Infill Definition Drilling In addition to the extensional drilling at depth, extensive definition drilling has taken place in the Wombat zone from depths between 410 metres and 470 metres below surface. This has further clarified structure, confirmed continuity of high grade zones and defined gold-rich zones in the hangingwall. Full results are appended in table 2. Highlights are 33 metres at 3.2% copper and 1.0g/t gold and 35 metres at 2.1% copper and 1.1g/t gold.
