New Drill Intercepts Show
Deeper Mining Potential at Taldybulak
· Assay results have been received from the first five drillholes in the current 2,500m diamond drilling programme at Taldybulak with significant gold and copper intersections in each drillhole.
· Drilling results also confirm that the Taldybulak deposit's gold and copper grades increase with depth.
· Diamond drill-hole TB0116 targeted deeper potential mineralisation of the highly prospective sheeted vein system, located in the gold-rich core of the Taldybulak deposit. TB0116:
o Ended in high-grade gold (2.84 g/t) and copper (0.5%) at 315.1m depth
o Intersected 53.1m @ 2.46 g/t Au and 0.31% Cu (2.97 g/t AuEq¹) from 262m to the end of the hole and includes an even higher grade zone:
§ 22.2m @ 3.52 g/t and 0.44% Cu (4.26 g/t AuEq¹) from 262m.
· This higher-grade gold mineralised zone remains open and shows increasing gold and copper grades with depth.
· Results expected to generate improved mineral resource classification and increased estimates of metal content.
Tengri Resources (AIM:TEN) the mining exploration and development Company focused on high quality low cost gold-copper projects in Central Asia, is pleased to announce assays results from its ongoing 2015 drilling campaign at its 100% owned Taldybulak gold and copper project.
All five drillholes assayed to date have intersected wide intervals of gold and copper mineralisation. Extensive higher-grade intervals are reported, including 22.2m @ 4.26 AuEq¹ in hole number TB0116.
Following the successful negotiation of a social license with local communities in 2014, Tengri has conducted two drilling campaigns (2014 and 2015) at the Taldybulak project, Kyrgyz Republic. This work has resulted in the delineation of a "sheeted vein system", located in the core of Taldybulak's large porphyry gold-copper deposit. The sheeted vein system hosts significantly higher gold and copper grades than the global Taldybulak resource average. Tengri's Phase 1 mining plan will consist of mining the upper part of the sheeted vein domain and Phase 2 will be the extension of Phase 1 incorporating both the ore at depth and ore supplied from the Andash Mine.
The results reported today have identified new higher-grade zones at moderate depths, which the technical team believes will have positive implications for extensions of the existing resource, and potential exploitation by a deeper Phase 2 open pit and/or by low-cost bulk underground mining methods.
In the current drill program, seven drill holes have now been completed totalling 1,739 metres. Assays of the first five drill holes (TB0112-TB0116) are now available and significant intersections of gold copper and molybdenum are shown in Table 1. Table 2 lists the position and target details for the five holes. Drilling continues at Taldybulak.

Executive Chairman Mr Gary Lewis said:
"The intersection of high-grade mineralisation at Taldybulak in our recent drilling provides further evidence of the effectiveness of our phased development program.
Our priority remains completing the Scoping Study for Taldybulak Phase 1 this calendar year. Phase 1's open pit and mid-level mine and mill throughput will aim to mitigate capital and operating risk, underpin infrastructure and community development and engagement and provide solid economic returns.
Thereafter we will be well placed to execute a seamless expansion to Phase 2. The mine plan currently incorporates an expanded open pit mine and increased mill throughput, and today's discovery of deeper higher-grade gold and copper mineralisation presents a potentially viable option for low cost underground bulk mining of Taldybulak to greater depth to access higher grade material identified by the deeper drilling. Indications are that Taldybulak ore, coupled with feed from satellite deposits such as Andash and Tengri's other highly prospective regional exploration targets, may become the focus of a long-life, world-class gold/copper mining and processing operation."
A supporting technical presentation for this RNS will be posted to the Tengri Resources website at: www.tengriresources.co.uk.
