88 | ASIA Miner | September/October 2014 Exploration ARCHER Exploration has announced a combined JORC 2012 graphite resource at its Eyre Peninsula project in South Australia of 8.55 mil- lion tonnes @ 9.0% graphitic carbon for 770,800 tonnes of contained graphite. This is the largest JORC 2012 graphite resource in Australia. The Eyre Peninsular project encompasses the Campoona and Sug- arloaf deposits as well as the recently acquired Wilclo South area. The estimate is based on a 5% cut-off grade and utilizes the JORC 2012 defnition of 'reasonable prospects of eventual recovery'. Archer's managing director Gerard Anderson says, "With exposure to large fake graphite at Wilclo South and high purity graphite at Cam- poona, we now have a range of fake sizes across our tenements that allows us to target a wide spread of end graphite users." "Our access to infrastructure and location in a safe and reliable mining jurisdiction provides us with a competitive position as the project is developed further." At Campoona Shaft there are 320,000 measured tonnes @ 12.7% for 40,600 tonnes of contained graphite, 780,000 indicated tonnes @ 8.2% for 64,000 tonnes and 550,000 inferred tonnes @ 8.5% for 46,800 tonnes. At Central Campoona there are 220,000 indicated tonnes @ 12.3% for 27,100 tonnes and 300,000 inferred tonnes @ 10.3% for 30,900 tonnes. At Wilclo South there are 6.38 million inferred tonnes @ 8.8% for 561,000 tonnes. The Wilclo South resource estimate represents only a very small strike length, 1.4km, of the more than 10km of strong linear EM conductors. There is signifcant potential for further resource growth. In addition to the Wilclo trend there are fve other graphite prospects corresponding to strong linear EM conductors aggregating an additional 10km of po- tential strike that has been the subject of only limited drilling. Gerard Anderson says, "Given our strong fnancial position, our im- mediate next step will be to drill test our additional graphite prospects to further build on our resource base and enable a ranking of deposits based on deposit size, graphite size distribution and purity of graphite in concentrates." The company is also undertaking a re-design of the process fow sheet for the proposed Sugarloaf processing plant in order to accom- modate the large fake graphite product and the high purity graphite ex- pected to be produced from Wilclo South and Campoona respectively. The expanded graphite resource and the new process fow sheet will underpin a scoping study which will assess the potential viability of the Eyre Peninsula project. All reported resources are within a 30km radius of the proposed graphite processing facility at Sugarloaf. TRENCHING by White Cliff Minerals at the Aucu copper-gold prospect in the Kyrgyz Republic has extended previously identifed mineralized zones and uncovered new zones. The Aucu prospect is northwest of the company's Chanach copper-gold deposit. Trench results include: 2 metres @ 3.23% copper and 4.5 grams/ tonne, including visible gold in the last sample with the trench now being extended; 5 metres @ 3.2 grams/tonne gold and 2 metres @ 2 grams/tonne; and 3 metres @ 2.4 grams/tonne gold and 0.67% copper. Trench 2A has extended the high grade copper-gold zone to the east while trenches 15 and 21 extend the confrmed strike length of the lower gold zone to 120 metres in a west-north-west orientation. The lower zone has also been exposed in a recent bulldozer cutting. In addition, rock chip sampling on an adjacent ridge 300 metres east has identifed a new zone of copper mineralization with initial results of 2.4% and 1.4% copper. These results confrm and extend the original trench results of 10 metres @ 2.94% copper and 8 grams/tonne gold, including 3 metres @ 7.7% copper and 19.8 grams/tonne gold, and 22 metres @ 2.5 grams/tonne, including 4 metres @ 4.5 grams/tonne and 5 metres @ 5.5 grams/tonne. Five mineralized zones have been identifed to date – the high grade copper-gold zone, the lower gold zone, north copper zone, east cop- per zone and lower copper-gold zone. While multiple trenches have been completed the trenches on the steep slopes either side of the ridges have gravel and soil up to 2 me- tres thick covering the bedrock making manual trenching by hand very diffcult. The company has adapted the trenching program to include more bulldozer cuts in these areas to expose bedrock and enable ef- fective sampling. There have been eight trenches completed to date with mineralization identifed in fve trenches. White Cliff has completed bulldozer access tracks up to 2900 me- tres elevation and is cutting trenches to expose mineralized zones on the fanks of the ridges. Further sampling will be conducted along the trenches prior to commencing a drilling program. The company expect- ed to start drilling in late August to test the potential for mineralization at depth. The Chanach project covers 83sqkm and is 350km west-southwest of the Kyrgyz capital of Bishkek. It is in the western part of the Tien Shan Belt, a highly mineralized zone that extends for more than 2500km from western Uzbekistan, through Tajikistan, the Kyrgyz Republic and south- ern Kazakhstan to western China.
