2014 Drilling Programme Results from Taldybulak Project, Kyrgyz Republic

 

2014 drilling programme completed with 13 drillholes totalling 2,029 metres,12 drillholes which intersected significant sheeted-vein style gold mineralisation at or near surface;

Results substantially improve the delineation of the near-surface and higher-grade gold sheeted-quartz vein system within the Taldybulak deposit and support the phased development strategy;

Final results reveal an average gold grade more than 3.6 times higher than the existing SAMREC resource: 1.66 g/t Au and 0.28 % Cu, using a 1 g/t AuEq cut-off, with excellent structural trend continuities;

Final Results include:

o 39 metres at 3.11 g/t Au, from 25 metres depth (TB0103)

o 23 metres at 1.58 g/t Au, from 113 metres depth (TB0103)

o 19 metres at 1.50 g/t Au, from 71 metres depth (TB0104)

o 11 metres at 2.25 g/t Au, from 137 metres depth (TB0104)

o 23 metres at 2.32 g/t Au, from 85 metres depth (TB0107)

o 26 metres at 1.91 g/t Au, from surface (TB0109)

o 34 metres at 1.76 g/t Au, from surface (TB0110)

o 16 metres at 1.82 g/t Au, from 132 metres depth (TB0110)

Phase 1 Feasibility Study underway, targeting medium-scale open pit mining and processing of the higher-grade, near-surface, gold-rich sheeted vein domain; and

2015 drilling programme developed to both expand the Taldybulak resource and further improve the resource classification of the identified Phase 1 area.

 

Tengri Resources (AIM: TEN) is pleased to announce the final results from its 2014 diamond drilling programme at its 100% owned Taldybulak Project, Kyrgyz Republic.

Taldybulak is large gold-copper porphyry deposit containing a mineral resource of 6.73 million ounces of gold and 1.67 billion pounds of copper. Detailed resource information is referenced in Table 3 below.

The 2014 drilling programme was completed comprising 13 drillholes and 2,029 metres. This programme was designed to test the near-surface portion of the sheeted-vein geological domain contained within the larger global 6.7Moz Au deposit. This strategy was not the primary focus of historic exploration conducted by previous owners, and therefore was not optimally drilled in the past.

Of the 13 drillholes, 12 intersected significant sheeted-vein style gold mineralisation from or near the surface. These drillholes returned a weighted average grade of 1.66 g/t Au and 0.28 % Cu, calculated using a 1 g/t AuEq(i) cut-off. This gold grade is more than 3.6 times higher than the average grade of the existing total global SAMREC resource. The gold intervals from this programme exhibit excellent continuity along structural trends established within the higher-grade sheeted-vein domain.

Phase 1 Feasibility Study and 2015 drilling programme

The delineation of the near-surface and higher-grade gold sheeted-quartz vein system has led the Company to begin the Feasibility Study for Phase 1; an open pit mine initially targeting the high-grade zone.

Early indications are that considerable gold will be recoverable through straightforward gravity concentration, with the remaining gold and copper extracted in a clean gold-copper concentrate. A programme of metallurgical tests will be conducted during 2015 as part of the Feasibility Study to confirm the process flowsheet, including the proportion of gold likely to be recovered by gravity concentration.

The drilling programme in 2015 will aim to both expand the Taldybulak global mineral resource and further define the resource within the identified Phase 1 area. At least two holes dedicated for metallurgical testing will be drilled to supplement information gathered by the previous operators. Additional geotechnical holes are to be drilled to support the open pit mine design.

An accompanying technical presentation will be made available on Tengri's website and 2014 drilling results are provided in tabled form below. http://www.tengriresources.co.uk/.

Table 1 shows collar details of all 13 drillholes drilled in 2014. Table 2 shows the significant intervals of Tengri's 2014 drilling programme.

 

John Levings, director of Tengri, said:

"The final 2014 drilling results today reported from Taldybulak represent a considerable achievement for Tengri and the culmination of our operational focus since joining AIM in July last year. The grades intersected and the consistency of higher grade gold mineralisation confirms that the deposit hosts a significantly higher-grade gold deposit than its existing resource outlines.

"The 2014 drilling results offer more confidence as we press on with the Feasibility Study for a Phase 1 open pit mine targeting the high grade zone. They also support our decision to prioritise the accelerated two-phased development of Taldybulak. We continue to anticipate and look forward to reporting the outcomes of both Phase 1 and Phase 2 in due course."

(i) Formula defining AuEq = Gold Equivalent = gold assay + (copper assay / 0.60) where the number 0.60 represents the ratio where 0.60 % Cu = 1.00 g/t Au. This ratio was calculated and rounded to the nearest two digit number from the average of past 24 months, from February 2013 to January 2015 taken from published World Bank Commodity Price Data http://siteresources.worldbank.org/INTPROSPECTS/Resources/334934-1304428586133/pink_data_m.xlsx
