East Star Resources Plc announced the completion of the helicopter electromagnetic ("HEM") survey conducted over the Company's licences in the prolific Rudny Altai volcanogenic massive sulphide ("VMS") belt in Eastern Kazakhstan. Rudny Altai Region: Licences 847-EL and 914-EL (the "Licences") are located in the Rudny Altai region of Eastern Kazakhstan. Administratively, the Licences are within the Shemonaikha district and are well connected to infrastructure.

The regional centre of Ust-Kamenogorsk is located 45km, and its international airport is located 35km, southeast of the Licences. The railway connecting Ridder and Tomsk cities crosses the Licences from the south to the northwest with two railway stations located on the territory of the Licences. There is a network of dirt roads within the Licences that are suitable for driving all year round.

A hard-surfaced road from Ust-Kamenogorsk to Shemonaikha crosses the western part of the Licences. The area is characterised by moderately hilly terrain with elevations ranging between 270m and 630m above the mean sea level. The Rudny Altai region is one of the largest VMS provinces in the world, part of Central Asian Orogenic belt.

The region is an established mining district with a number of active and historical mines bordering the Company's licence area.  Historical mapping dating back to the 1960s identified more than 20 mineral occurrences (including Cu, Pb, Zn, Au, W) and a significant amount of soil and stream sediment anomalies within the licence area. Geologically, the area is composed of volcanic, volcanic-sedimentary, and sedimentary deposits of the Devonian. Extrusive-subvolcanic formations are generally represented by rocks of felsic, medium and mafic composition, with the predominance of felsic rock (albitophyres, potassium feldspar porphyry, rhyodacites, less often andesite and andesite-basalt porphyrites).

Intrusive formations include mainly granites. HEM Survey: A HEM survey was conducted over 614.3km2 to identify hidden or buried VMS ore bodies. HEM is the principal technology used in the Paterson province of Western Australia which was used to discover Rio Tinto's 'Winu' deposit and Greatland Gold/Newcrest's 'Havieron' deposit.VMS deposits produce significant electromagnetic responses and thus this technology is the best geophysical method available for detecting ore bodies of this type, under cover.

Geophysical responses become direct exploration vectors for the identification of drilling targets. Aurora and Xcalibur: Xcalibur Multiphysics ("Xcalibur") conducted the EM survey and is the world's leading company in Multiphysics. It owns 20 specialised aircraft and 85 geophysical systems and has executed more than 1,000 projects globally.

Throughout its over 40 years of experience, Xcalibur has established more than 50 million linear kilometers of collected data. Aurora Minerals Group, a leading service provider in Kazakhstan, led the logistics and execution of the EM programme. Aurora has conducted exploration programmes for Kazzinc, Rio Tinto, Fortescue Metals Group, Tau-Ken Samruk, and KAZ Minerals.
