EMED Mining's exploration in Eastern Europe is currently focussed on exploring for gold deposits in Central Slovakia in the Company's 100%-owned Detva and Stiavnica-Hodrusa Licences. In October 2006, EMED Mining announced a gold discovery at Biely Vrch within the Detva Licence in Slovakia. Drilling at Biely Vrch during 2007 and 2008 culminated in an initial JORC Code-compliant Mineral Resource estimate of 1.1 million ounces of contained gold. Detva Licence Area The Detva licence area is located about 25 km to the east of the Stiavnica-Hodrusa district. The geology consists of a caldera-graben complex in the centre of a large stratovolcano. Widespread propylitic and localised advanced argillic alteration in the application area indicate substantial hydrothermal activity. This setting is analogous to of the Stiavnica-Hodrusa mineral field and is considered to be a classic geological setting for the formation of large porphyry and epithermal gold orebodies. By the end of 2008, EMED Mining had completed a diamond drilling programme of 34 holes has been completed on a 100m by 100m grid pattern at the Biely Vrch porphyry gold deposit. Gold mineralisation is contained in a broadly pipe-shaped quartz-veinlet stockwork zone associated with an andesitic porphyry intrusion. A number of drillholes are mineralised over their entire length from surface. Assay results have so far defined gold mineralisation in a vertical pipe-shaped structure to a depth of 300m below surface. The initial JORC-standard Mineral Resource for the Biely Vrch porphyry gold deposit totals 41.7 million tonnes at 0.79g/t gold, containing 1.1 million ounces of gold. The Mineral Resource measures approximately 350m north-south and 300m east-west and extends from surface to a depth of 250m. Mineralisation within a vertical pipe-shaped structure continues below this depth. Initial metallurgical testwork of Biely Vrch drill core samples indicates the gold mineralisation is not metallurgically complex and recoveries can be expected to be consistent with analogous porphyry gold projects in other parts of the world.
Porphyry gold deposits differ to the more common porphyry copper-gold deposits, and typically:
The recognition of Biely Vrch as a porphyry gold deposit has provided valuable insights which assist EMED Mining's plans for exploration of its Slovakian licences. Stiavnica-Hodrusa Licence Area The Company's granted licence covers a substantial portion of this world-class mineral district in Slovakia. Underground mines in this district have historically yielded an estimated total of 2.4 million ounces of gold, 120 million ounces of silver, 70,000 tonnes of zinc, 55,000 tonnes of lead and 8,000 tonnes of copper. This historical production has been sourced from narrow, high-grade epithermal veins. EMED will be the first company to test systematically for large bulk-mineable, near-surface disseminated styles of mineralisation in this prolific district. EMED Mining has recognised a variety of styles and the potential for porphyry, skarn and stockwork styles of gold mineralisation that have not been investigated by previous explorers. In addition, EMED has recognised areas of potential for high-sulphidation epithermal style of gold mineralisation. This style is commonly only weakly anomalous in gold at surface, but can host extensive high-grade gold deposits at depth. Of the areas prospective for porphyry style of gold mineralisation, the Zlatno and Sementlov prospects have been investigated during the Soviet era for copper but not gold. These two prospects both display alteration typically associated with deep porphyry stocks extending to the surface. At Zlatno, extensive drilling during the Soviet era has been reported by the State Geological Survey of Slovakia as having delineated a low-grade copper-porphyry/skarn deposit at a depth which is of no interest to EMED but does indicates the presence of mineralisation styles targeted by EMED. No testing for gold was done during the Soviet era, other than analysis in one hole which "the presence of gold". Several skarn bodies occur in the northwest portion of the licence area. These skarns have been investigated for industrial magnetite, but have not been tested for gold.
