Discovery of New Vein Extension & Exploration Update

 Trans-Siberian Gold plc (TSG.LN), a low cost, high grade gold producer in Russia, is pleased to announce the discovery of a new vein extension at its Asacha Gold Mine and to provide an exploration update. The newly discovered zone, Vein 25 North, is located approximately 400 metres north of Vein 25, within the East zone of the Asacha Gold Mine and has delivered encouraging drilling results.


  • Discovery of an extension of Vein 25, Vein 25 North, some 400 metres to the north
  • Initial drilling results have provided some high-grade intersections, including:
    • C1915: 133 g/t Au, 57 g/t Ag over 4 m
    • C1918: 22 g/t Au, 69 g/t Ag over 1 m
    • C2002: 89 g/t Au, 109 g/t Ag over 0.5 m
    • C2006: 10 g/t Au, 244 g/t Ag over 2.5 m
    • C2009A : 13 g/t Au, 194 g/t Ag over 2.3 m
    • C2010 : 59 g/t Au, 99 g/t Ag over 1.8 m
  • 400m area between Vein 25 North and Vein 25 remains undrilled except for one hole, SRK-001 that gave 22 g/t Au, 56 g/t Ag over 0.8 m
  • Discovery of a new vein system about 150 meters east of Vein 25 North
    • C2006: 28 g/t Au, 42 g/t Ag over 3.4 m
  • New geological interpretation identified 6 high priority targets, including Vein 25 North
  • Total of 8,200 m drilled in 2019 on Vein 25 and Vein 25 North
  • Total of 25,000 m planned for the 2019-2020 drill campaign over the Asacha licence area
  • Capital expenditure of up to $7.9 million allocated for development and exploration
  • Updated Mineral Resource Estimate for Rodnikova expected in first quarter of 2020
  • Senior consultant with significant experience of epithermal vein deposits retained to oversee the new in-country exploration team & work programme


Alexander Dorogov, CEO of Trans-Siberian Gold commented:

“We are very pleased with the strong operational performance delivered in 2019 and are accelerating our investment in the exploration and development of the Asacha Gold Mine. The recently conducted drilling programme has yielded some exciting, high grade mineralisation results at Vein 25; this is an important development target for the extension of resource mineralisation. We have an ambitious exploration programme planned in 2020 and with drilling continuing we look forward to updating the market on our progress.”


2020 Exploration Priorities

The Company has established the following priorities for 2020:

Main Zone Asacha


East Zone Asacha



· North Extension

· South Extension Deep

· Vein 18

· Vein K2

·   V25N & V25 infill drilling

·   Resource base verification

·   Pre-mining technical studies

·   JORC Mineral Resource publication

·   Exploration drilling

·   Internal Scoping Study

·   Selected M&A opportunities 

·   Judicious investments or JVs

 The low sulfidation epithermal style of mineralisation found at the Asacha Gold Mine is favourable for high-grade deposits. The Asacha licence area and more widely, the regional district, remain under-explored which the Company believes presents an opportunity to increase gold resources. As such, the Company has ramped up the scope and scale of its exploration activities. A recent data compilation and new geological interpretation produced 6 high priority targets (see Figure 1)
