The Sihayo Gold Project lies in the prolific Trans Sumatra Fault Zone (TSFZ), which is host to several gold projects with significant reserves and resources. The project lies within the 66,200ha Sihayo Pungkut JV 7th generation Contract of Work (CoW), of which Sihayo Gold Limited has a 75% interest in. The CoW exhibits significant potential for gold mineralisation and SIH has delineated several targets on the CoW to explore and upgrade its resource potential.

While the Company progresses development of its Sihayo Gold Project, Sihayo has formulated and progressed a 3-tier exploration strategy across the CoW. The main essence of the strategy includes:

  • Targeting additional resources within trucking distance of the Sihayo Gold Project
  • Identifying and exploring targets on the Hutabargot Julu Prospect
  • Regional exploration strategy to increase mineral resources and reserves of the project.
